BACKGROUND
[0003] Home entryways are sensitive areas often associated with the
security and peace of mind of the home's occupants. Homeowners and
occupants have an interest in monitoring their entryways for
security and convenience. Some existing surveillance systems detect
persons in the field of view of a security camera, and some
initiate a general alert upon such detection. However, a single
type of alert is not appropriate for all detected persons; some
persons may be welcome guests, occupants, unwelcome visitors, or
merely persons passing by the entryway.
[0004] It is a challenge to accurately identify and categorize
visitors to a home. It is also a challenge to provide meaningful
options to occupants of the home for responding to such visitors.
Human-friendly techniques for discovering and categorizing
visitors, as well as providing relevant options to users for
responding to the visitors are in great need.
SUMMARY
[0005] Accordingly, there is a need for systems and/or devices with
more efficient, accurate, and intuitive methods for entity (e.g.,
person) and event identification, categorization, and presentation.
Such systems, devices, and methods optionally complement or replace
conventional systems, devices, and methods for entity and event
identification, categorization, and/or presentation. Further, there
is a need for systems and/or devices with more efficient and
intuitive methods for identification and presentation of actions
associated with responding to entities and events. Such systems,
devices, and methods optionally complement or replace conventional
systems, devices, and methods for action identification and
presentation.
[0006] Users of home monitoring systems can potentially be
bombarded with alerts and notifications about unimportant and
trivial events if the systems do not employ some
recognition/identification and categorization processes. The large
number of unnecessary or incomplete information places a larger
burden on the users and makes it more difficult to identify and
respond to important events. For example, a user who receives
entryway motion notifications every time a person walks in front of
a camera mounted at an entryway of the home may not be able to
distinguish between passersby and visitors. Thus, it is beneficial
to be able to recognize when a detection event is caused by a
visitor approaching the entryway. It is also beneficial to be able
to recognize contextual information regarding the person's actions
in distinguishing whether the person is a visitor approaching the
entryway. For example, rather than sending a notification stating
that "motion was detected," the system could send a notification
detailing that "an unknown person is approaching the front door,"
or "an unknown person has been waiting by the front door for the
past 30 seconds and has not yet rang the doorbell." The user can
see at a glance the nature of the event and request more details
(e.g., a clip of the event) and/or generate a response (e.g., alert
the authorities, or initiate a communication). Further, by
recognizing contextual information during the visitor's approach,
the home monitoring system can determine relevant information for
the user before the visitor reaches the entryway. Accordingly, by
the time the visitor has reached the entryway and rings the
doorbell or knocks on the door, the home monitoring system has
already recognized enough contextual information to send relevant
information to the user or take appropriate actions without having
to wait for the visitor to reach the entryway, thereby increasing
the efficiency of the system for both the user (e.g., can respond
more quickly to a detection event) and the visitor (e.g., can
interact with the home monitoring system with little to no
processing delay).
[0007] In addition, users of home monitoring systems often have
limited options available for responding to a detected visitor.
Further, if an arbitrary subset of available options is presented,
they may not be relevant to the situation at hand. Thus, it is
beneficial to have a wide range of options available for responding
to a visitor, such as alerting the authorities, initiating two-way
communication with the visitor, adjusting security settings in the
home, and the like. Moreover, it is beneficial to be able to
recognize contextual information regarding the visitor and present
an appropriate subset of the options that are relevant to the
specific situation. For example, if a known visitor approaches the
entryway, the system can provide a subset of actions that are
appropriate for a known visitor (e.g., a greeting, and/or an option
to unlock the door). On the other hand, if an unknown visitor
approaches the entryway, the system can provide a different subset
of actions that are appropriate for an unknown visitor (e.g., a
warning, an option to lock the door, and/or an option to call the
authorities).
[0008] In one aspect, some implementations include a method for
recognizing an approaching visitor and initiating a response based
on context information. In some implementations, the method
includes: (1) determining that a visitor is approaching an
entryway; (2) initiating a facial recognition operation while the
visitor is approaching the entryway; (3) initiating an observation
window in response to the determination that the visitor is
approaching the entryway; (4) obtaining context information from
one or more sensors of the smart home environment during the
observation window; and (5) at the end of the observation window,
initiating a response to the detected approach of the visitor based
on the context information and an outcome of the facial recognition
operation.
[0009] In some implementations, the observation window is initiated
before the visitor reaches a physical interaction area of the
entryway, the physical interaction area being defined a region in
which the visitor is close enough to the entryway to physically
interact with an element of the entryway, such as a door, a
doorbell, a paging system, or a component of the electronic
greeting system. For example, the observation window is initiated
and context information (for use as a basis for initiating a
response) is obtained before the visitor is close enough to ring
the doorbell or knock on the door.
[0010] In some implementations, the observation window is initiated
(and context information is obtained) at any time before the
visitor initiates an announcement, such as a door knock, a doorbell
button press, a verbal announcement, or a physical interaction with
a component of the electronic greeting system. For example, even if
the visitor is close enough to the entryway to ring the doorbell or
knock on the door, the observation window is initiated and context
information is obtained at any time before the visitor actually
rings the doorbell or knocks on the door (or makes any other kind
of announcement).
[0011] In some implementations, determining that a visitor is
approaching the entryway includes obtaining and analyzing presence
information indicative of an approaching visitor or a visitor in
proximity to the entryway. In some implementations, part or all of
the presence information is derived from motion data of one or more
motion sensors of the smart home environment, including, for
example, a passive infrared (PIR) sensor, an ultrasonic sensor, a
microwave sensor, and/or a tomographic sensor. In some
implementations, part or all of the presence information is derived
from video data of one or more cameras having a field of view
corresponding to the entryway. For example, presence information is
derived by determining that an amount of motion detected by a
camera or other type of motion sensor meets one or more motion
criteria, such as an amount of motion exceeding a threshold. As a
further example, presence information is derived by analyzing a
plurality of image frames to determine whether a difference in
position of an object (e.g., measured in pixels) in the plurality
of image frames exceeds a threshold. In some implementations, part
or all of the presence information is derived from an audio signal
obtained from an audio sensor. For example, an audio signal
capturing an audio event (such as a footstep, a verbal
announcement, a doorbell sound, or a door knock) is indicative of a
visitor's presence.
[0012] In some implementations, determining that a visitor is
approaching the entryway includes comparing a dimension of a
characteristic of the visitor over time. In some implementations,
determining that the visitor is approaching includes tracking one
or more dimensions of the visitor over time. For example,
determining that a visitor is approaching the entryway includes
obtaining a first measurement of a dimension of a characteristic of
the visitor (such as an initial height measurement of the visitor's
head), obtaining a subsequent measurement of the dimension of the
characteristic of the visitor (such as a second height measurement
of the visitor's head at a predetermined amount of time after the
initial height measurement), and determining whether a difference
between the first measurement and the subsequent measurement
exceeds a threshold. For example, if the visitor's head height
increases between the first and second measurements, the visitor is
likely approaching; otherwise, if the visitor's head height does
not increase, the visitor is likely not approaching or is standing
still.
[0013] In some implementations, determining that a visitor is
approaching the entryway comprises determining that the visitor is
within a threshold distance to the entryway. For example, if a
person is detected within a predetermined distance from the
entryway, the person is determined to be an approaching visitor.
For example, once the visitor is within 15 feet, 10 feet, or 5 feet
of the entryway, the observation window is initiated, and context
information is obtained. In some implementations, initiating the
observation window in response to the determination that the
visitor is approaching the entryway includes initiating the
observation window in response to the determination that the
visitor is on a track to the entryway (e.g., has entered a walkway,
hallway, or perimeter gate leading to the entryway).
[0014] In some implementations, determining that a visitor is
approaching the entryway includes deriving a motion stream. In some
implementations, the motion stream is a data stream derived from a
video stream of the camera, wherein the data stream serves as a
basis for motion analysis. In some implementations, the motion
stream is derived from the video stream by detecting information
regarding an amount of motion in a field of view of the camera, or
by comparing an amount of detected motion in a field of view of the
camera to a threshold. In some implementations, the motion stream
includes a motion mask for a motion event detected in the video
stream.
[0015] In some implementations, the method further includes
capturing from the motion stream a crop of a face of the visitor
when a size of the face exceeds a threshold proportion of a frame
of the motion stream. For example, once the visitor is within a
threshold distance to the camera (e.g., 10 feet, 5 feet, or 3 feet)
the camera generates a cropped image of the visitor's face.
[0016] In some implementations, determining that a visitor is
approaching the entryway includes obtaining position data from a
sensor of the smart home environment; identifying, based on
analysis of the position data, a position of the visitor with
respect to the entryway; and comparing the position of the visitor
to a threshold distance from the entryway, or to a previous
position of the visitor.
[0017] In some implementations, determining that a visitor is
approaching the entryway includes detecting the visitor entering or
occupying a user-defined activity zone. For example, if the visitor
enters a zone defined by a 3-foot radius around a delivered
package, the system determines that a visitor is approaching. This
information is also a useful basis for contextual information,
described below.
[0018] In some implementations, determining that a visitor is
approaching the entryway includes detecting at least one of a face,
height, shape, or movement characteristic (e.g., a particular
walking style such as limping) of the visitor. In some
implementations, a visitor profile for a particular visitor is set
(e.g., set manually by a user, or set via machine learning) to
associate a particular face, height, shape, or movement
characteristic with the visitor.
[0019] In some implementations, context information is obtained
only while the visitor is approaching and before reaching a
predetermined distance (e.g., in proximity) of the entryway. In
some implementations, context information is obtained both while
the visitor is approaching and while the visitor is in proximity to
the entryway. In some implementations, context information is
obtained only while the visitor is in proximity to the
entryway.
[0020] In some implementations, context information includes a
detected announcement event (e.g., a doorbell button press, a door
knock, or a verbal announcement), or an absence of detected
announcement events during a predetermined time threshold. For
example, a visitor who rings the doorbell within 5 seconds of
reaching the entryway may warrant a different response from the
electronic greeting system than a visitor who has reached the
entryway but has lingered for more than 30 seconds without ringing
the doorbell or knocking on the door. In some implementations, a
doorbell press, door knock, or verbal announcement is part of a
pre-assigned pattern of doorbell presses or door knocks associated
with, or is otherwise associated with, a known visitor. For
example, the smart home environment (e.g., a smart doorbell)
determines that a particular visitor always knocks at a particular
location on the door, in a particular pattern, and with a
particular amount of force. In this example, the smart home
environment associates such knock attributes with the particular
visitor. In another example, a visitor profile for a particular
visitor is set (e.g., set manually by a user, or set via machine
learning) to associate a particular knock pattern, a particular
doorbell ring pattern, or a particular verbal announcement with the
particular visitor.
[0021] In some implementations, context information is based on a
facial recognition analysis result, one or more behavior
characteristics of the visitor, one or more physical
characteristics of the visitor, one or more clothing and/or
accessory characteristics of the visitor, a time of day during
which the visitor approaches the entryway, a day of the week during
which the visitor approaches the entryway, audio data from the
smart home environment, proximity in time to a prescheduled event,
proximity in time to a prescheduled status of the smart home
environment, a known or unknown status of a user of the electronic
greeting system, an expected or unexpected status of a user of the
electronic greeting system, a location of a user of the electronic
greeting system, an identity of a user of the electronic greeting
system, and/or one or more detected visitor actions (e.g., a
doorbell activation, a door knock, an audio announcement, and/or
any other interaction between the visitor and the electronic
greeting system). In some implementations, the context information
is based on a timing of the one or more detected visitor actions
(e.g., how long it took for the visitor to press the doorbell or
knock on the door since the visitor was detected or was determined
to have been approaching or in proximity to the entryway, or how
long the visitor has been lingering without pressing the doorbell
or knocking on the door since the visitor was detected or was
determined to have been approaching or in proximity to the
entryway).
[0022] In some implementations, the context information includes
characteristics of the visitor, such as height, gender, age, and
the like. In some implementations, the context information includes
determined biometrics of the visitor. In some implementations, if a
group of visitors approach the entryway together, the context
information includes the number of visitors and/or identified
interactions between the visitors. In some implementations, the
context information includes information regarding whether the
visitor is holding any items and/or identification of such items
(e.g., a box, crowbar, or food items). In some implementations, the
context information includes information regarding any active or
recent (e.g., within the last hour, day, or week) security alerts
in the vicinity of the smart home (e.g., within a block, a mile, or
10 miles). In some implementations, the context information
includes information regarding previous visitors to the smart home
(e.g., whether previous visitors were criminals, salesmen, or
neighbors).
[0023] In some implementations, the observation window ends at the
earlier of: (1) a predetermined time threshold; and (2) a detected
visitor announcement. For example, if a responsive visitor rings a
doorbell or knocks on the door, the observation window ends
regardless of whether the predetermined time threshold is reached,
allowing for a prompt response by the electronic greeting system.
As another example, if a lingering visitor has not pressed a
doorbell button or knocked on the door by the time the
predetermined time threshold is reached, the observation window
ends even though the visitor has not yet made an announcement,
allowing for a prompt response by the electronic greeting
system.
[0024] In some implementations, responding to the visitor includes
conveying a communication to the visitor; initiating a security
action; and/or transmitting a notification to a user of the
electronic greeting system, to a preselected contact of the user,
and/or to public or private law enforcement personnel.
[0025] In some implementations, the communication includes at least
one of: a communication conveying a status of a user of the
electronic greeting system; a communication directing the visitor
to perform an action; a communication directing the visitor to
leave a message; a preprogrammed customized communication; a
user-composed text message for conversion to an audio message; an
audio communication conveyed by a synthesized voice; and/or a
visual communication presented on a display.
[0026] In some implementations, the security action includes at
least one of: activating a light or adjusting a lighting level of
the smart home environment; locking or unlocking a door of the
smart home environment; activating an alarm or adjusting an alarm
sensitivity of the smart home environment; activating a sprinkler
system of the smart home environment; activating a simulated dog
bark; activating a security system or adjusting a security status
of the smart home environment; transmitting a notification or an
alert to public or private law enforcement personnel; transmitting
a notification or an alert to a preselected contact of the user;
and/or recording an image or video of the visitor.
[0027] In some implementations, the notification includes at least
one of: information about the visitor; information about an outcome
of the facial recognition operation; information about a detected
visitor announcement event or lack thereof; and/or information
about the obtained context information.
[0028] In another aspect, some implementations include an
electronic greeting system of a smart home environment including:
(1) a camera; (2) one or more processors; and (3) memory coupled to
the one or more processors, the memory storing one or more programs
configured to be executed by the one or more processors. In some
implementations, the one or more programs include instructions for
implementing one or more of the above operations.
[0029] In another aspect, some implementations include a
non-transitory computer-readable storage medium storing one or more
programs. In some implementations, the one or more programs include
instructions, which when executed by a computing system, cause the
system to implement one or more of the above operations.
[0030] In another aspect, some implementations include a method of
providing appropriate actions for responding to or interacting with
a visitor to a smart home environment. In some implementations, the
method includes: (1) detecting a visitor of the smart home
environment; (2) obtaining context information from the smart home
environment regarding the visitor; (3) based on the context
information, identifying a plurality of appropriate actions
available to a user of a client device for interacting with the
visitor via the electronic greeting system; and (4) causing the
identified actions to be presented to the user of the client
device. For example, the smart home environment may detect a
deliveryman approaching with a box and send the smart home user
appropriate actions (sometimes referred to herein as "quick
actions") enabling the user to (1) instruct the deliveryman to
leave the box on the porch, (2) instruct the deliveryman to retry
delivery at a later time, or (3) ask the deliveryman if a signature
is required for delivery.
[0031] In some implementations, (1) detecting a visitor includes
determining that (a) a visitor is approaching an entryway of the
smart home environment, or (b) a visitor is in proximity to an
entryway of the smart home environment. In some implementations,
determining that the visitor is approaching or in proximity to an
entryway includes any of the previously described aspects and
implementations.
[0032] In some implementations, (1) detecting a visitor includes
(a) obtaining motion data from the sensor; and (b) identifying,
based on analysis of the motion data, a motion event involving a
visitor approaching an entryway of the smart home environment. In
some implementations, (a) obtaining motion data includes: (i)
analyzing a plurality of image frames to determine whether motion
between two or more frames of the plurality of frames satisfies
motion criteria; (ii) analyzing infrared data from an infrared
sensor to determine whether a difference in infrared data satisfies
motion criteria; and/or (iii) analyzing data from a motion sensor
to determine whether the data satisfies motion criteria. For
example, the smart home analyzes a video stream to determine
whether an amount of motion present exceeds a preset motion
threshold. As another example, the smart home utilizes a passive
infrared (PIR) sensor to determine whether a distance between the
user and the smart home entryway is shrinking. In some
implementations, (b) identifying the motion event includes: (i)
detecting the visitor entering an activity area in proximity to the
entryway; (ii) detecting a face of the visitor; and/or (iii)
detecting at least one of a height, shape, and movement
characteristic of the visitor.
[0033] In some implementations, (2) context information is obtained
based on any of the previously described aspects and
implementations.
[0034] In some implementations, (2) context information is obtained
based on: (i) a facial recognition analysis; (ii) on one or more
behavior characteristics of the visitor; (iii) on one or more
clothing characteristics of the visitor; (iv) a time of day during
which the visitor approaches the entryway; (v) audio data; (vi)
proximity in time to a prescheduled event; (vii) proximity in time
to a prescheduled status of the smart home environment; (viii) a
status or location of the user; (ix) a detected visitor action
(e.g., a doorbell push, a door knock, an audio or verbal
announcement, and/or an interaction between the visitor and the
electronic greeting system); and/or (x) on a timing of a detected
visitor action (e.g., comparing a timing of the detected visitor
action with a timing of the identification of the motion event
involving the visitor approaching the entryway). In some
implementations, the context information includes information
regarding a location and/or status of the smart home user.
[0035] In some implementations, the plurality of appropriate
actions includes any of the responses in previously described
aspects and implementations.
[0036] In some implementations, the plurality of appropriate
actions includes: (i) one or more communication-based actions; (ii)
one or more action-based actions; (iii) one or more person-specific
actions; (iv) one or more location-specific actions; (v) one or
more building-specific actions; and/or (vi) one or more user
disposition-specific actions.
[0037] In some implementations, (i) one or more communication-based
actions include: (a) sending a message regarding a status of the
user; (b) sending a message directing the visitor to perform an
action; (c) sending a message directing the visitor to leave a
message; (d) sending a preprogrammed customized message to the
visitor; (e) sending a user-composed text message to be converted
to an audio message for the visitor; (f) sending an audio message
spoken by a synthesized voice to the visitor; and/or (g) sending a
visual message displayed on a screen to the visitor. In some
implementations, a user selection of a communication-based action
is received during a contemporaneous audio communication between
the user and the visitor.
[0038] In some implementations, (ii) one or more action-based
actions include: (a) adjusting a security level of the smart home
environment; (b) locking or unlocking a door of the smart home
environment; (c) adjusting a brightness level of a light of the
smart home environment; (d) alerting law enforcement personnel; (e)
alerting a preselected contact of the user; (f) recording an image
or video of the visitor; and/or (g) turning on an alarm of the
smart home environment.
[0039] In some implementations, (iii) one or more person-specific
actions are selected based on: (a) a status of the visitor (e.g.,
known, unknown, expected, or unexpected); (b) a detected identity
of the visitor; and/or (c) whether a visitor is expected when the
motion event is identified.
[0040] In some implementations, (4) identifying the plurality of
appropriate actions available to the user includes ranking one or
more actions based on the context information, and ordering the one
or more actions based on the ranking. In some implementations, a
number of identified actions to be presented to the user of the
client device is based on an amount of screen space available in a
quick action area of a user interface of the client device. In some
implementations, the number of identified actions to be presented
to the user of the client device is based on dimensions of the
client device. In some implementations, the number of identified
actions to be presented to the user of the client device is based
on an orientation of the client device. In some implementations,
identifying the plurality of appropriate actions available to a
user includes selecting N appropriate actions from a superset of P
appropriate actions, where N and P are integers and P is greater
than N, and identifying the selected appropriate actions as the
plurality of appropriate actions. In other words, the number of
appropriate actions displayed to the user is a subset of a master
list of appropriate actions.
[0041] In some implementations, the method further includes: (5)
receiving a selection of an identified action from the user of the
client device, and (6) causing the action to be performed. For
example, a smart home user selects a quick action requesting that a
visitor state why she is visiting. In this example, the user
selection triggers audio output by a speaker near the entryway
(e.g., a speaker on a smart doorbell device) relaying the
request.
[0042] In some implementations, the method further includes: (7)
obtaining additional context information based on a visitor
response to the performed action; (8) based on the additional
context information, identifying a subsequent plurality of
appropriate actions available to the user of the client device for
interacting with the visitor via the electronic greeting system;
and (9) causing the identified subsequent actions to be presented
to the user of the client device. In some implementations, the
method further includes: (10) receiving a subsequent selection of
an identified subsequent action from the user of the client device,
(11) and causing the subsequent action to be performed. For
example, the visitor from the prior example states that she is
visiting because she had a study session schedule with Susan, one
of the smart home occupants. In this example, the smart home may
then send a new set of quick actions to the smart home user,
including (a) an action to unlock the door, (b) an action to alert
Susan of the visitor, (c) an action to request that the visitor
wait for someone to answer the door, and (d) an action notifying
the visitor that Susan is unavailable and the study session must be
canceled.
[0043] In some implementations, the method further includes: (12)
continuously obtaining context information; (13) based on the
continuously obtained context information, continuously identifying
successive pluralities of appropriate actions available to the user
of the client device for interacting with the visitor via the
electronic greeting system; and (14) continuously causing the
identified successive pluralities of actions to be presented to the
user of the client device. In some implementations, the method
further includes (15) successively receiving one or more selections
of the continuously identified successive pluralities of actions
from the user of the client device, and (16) causing the one or
more selected actions to be performed.
[0044] In another aspect, some implementations include an
electronic greeting system configured to perform any of the methods
described herein. In some implementations, the electronic greeting
system includes means for performing any of the operations
described herein. In some implementations, the electronic greeting
system includes one or more cameras and a server system. In some
implementations, the electronic greeting system includes a doorbell
device having one or more microphones, one or more speakers, one or
more cameras, and a user interface (e.g., a touch screen and/or an
affordance for triggering the device).
[0045] Thus, systems are provided with more efficient and effective
methods for monitoring and facilitating review of events and
persons in video streams, thereby increasing the accuracy,
effectiveness, efficiency, and user satisfaction with such systems.
In addition, systems are provided with more effective methods for
responding to or interacting with persons in video streams, thereby
increasing the accuracy, effectiveness, efficiency, and user
satisfaction with such systems. Such systems and methods may
complement or replace conventional systems and methods for event
and person monitoring, presentation, response, and interaction.

DETAILED DESCRIPTION
[0064] Due to the potentially large number of alerts and
notifications associated with home monitoring systems, it is
beneficial to employ some recognition/identification and
categorization processes. For example, rather than notifying a user
every time a person walks in front of a camera mounted at an
entryway of the home, it is beneficial to be able to recognize
whether the motion event is caused by a visitor approaching the
entryway or by a mere passerby, and inform the user of the type of
event that occurred and the persons/entities involved. This enables
the user to more quickly and efficiently make a determination as to
whether the event requires any action or further review by the
user. In this way, the user can more quickly and easily distinguish
important events (e.g., events requiring an immediate response or
more detailed review) from trivial ones that do not require further
review or response. Further, the user can see at a glance the
nature of the event and request more details (e.g., a clip of the
event) and/or generate a response (e.g., alert the authorities, or
initiate a communication).
[0065] In addition, due to the many different scenarios in which a
visitor may approach a user's home, it is beneficial to have a wide
range of options available for responding to a visitor in such
scenarios, such as alerting the authorities, initiating two-way
communication with the visitor, adjusting security settings in the
home, and the like. Moreover, it is beneficial to be able to
recognize contextual information regarding the visitor and present
an appropriate subset of the options that are relevant to the
specific situation. For example, if a known visitor approaches the
entryway, the system can provide a subset of actions that are
appropriate for a known visitor (e.g., a greeting, and/or an option
to unlock the door). On the other hand, if an unknown visitor
approaches the entryway, the system can provide a different subset
of actions that are appropriate for an unknown visitor (e.g., a
warning, an option to lock the door, and/or an option to call the
authorities).
[0066] Accordingly, some implementations include a
network-connected electronic greeting system including a camera
that recognizes contextual information related to detected
visitors. In some implementations, when a visitor presses a
doorbell (or knocks or makes a verbal announcement), the system
sends an indication to the user's device (also sometimes referred
to herein as a client device and a portable electronic device;
e.g., a smartphone) that there was a visitor announcement (e.g., a
doorbell button press or a knock), and the user's device displays
an alert (or other type of notification). In some implementations,
the alert includes a video clip (e.g., a gif) and/or a static image
of the visitor. In some implementations, if the system senses a
motion event involving an approaching visitor, and the visitor does
not make an announcement (e.g., does not press the doorbell or
knock on the door) within a threshold amount of time, the system
sends an indication to the user's device that there is a visitor
that has not yet made an announcement (sometimes referred to herein
as a lingering visitor).
[0067] In some implementations, a user interface of the user device
includes an option to ignore the alert, an option to initiate a
voice or text-to-speech communication with the visitor, and an
option to display a list of suggested actions (also sometimes
referred to herein as quick actions). In some implementations, the
option to display quick actions is available before and during a
voice or text-to-speech communication session. In some
implementations, selecting the option to display quick actions does
not open a microphone on the user device, which enables the user to
respond without transmitting live audio of the user. For example,
if the user is in a meeting, or otherwise unable or unwilling to
transmit live audio, the user is still able to respond via the
quick actions.
[0068] In some implementations, a user interface of the user device
includes an option to have the smart home system interact with the
visitor (e.g., via a virtual assistant). Use of the virtual
assistant to interact with the visitor is also sometimes referred
to herein as a talkback interaction. In some implementations, the
smart home system provides the user with a summary of the virtual
assistant's interaction with the visitor.
[0069] In some implementations, the user may preprogram one or more
of the quick actions or assistant responses. In some
implementations, the user may preprogram a quick action or an
assistant response by speaking into a speaker device of the smart
home environment. In some implementations, the user may preprogram
a quick action or an assistant response by using a client device,
an electronic greeting system, a server system, or any other
suitable computer system associated with the smart home
environment.
[0070] In some implementations, at least a subset of the quick
actions are communication-based, such as sending a voice or
text-to-speech message, initiating a talkback interaction, and/or
initiating a prerecorded greeting. A prerecorded greeting or
warning message is optionally a recording of a person's voice
(e.g., the user's voice) or an artificial voice (e.g., a virtual
assistant's voice). In some implementations, at least a subset of
the quick actions are action-oriented, such as increasing a
security level of the smart home environment, locking or unlocking
a door, turning on or off a light, calling the authorities,
alerting a security company or other person associated with the
smart home (e.g., a neighbor), capturing a snapshot or video clip
of the visitor (e.g., and sending it to the authorities, or storing
it on a user-accessible server system), and/or turning on or off an
alarm. In some implementations, a list of presented quick actions
includes at least one communication-based quick action and at least
one action-oriented quick action. In some implementations, at least
a subset of the quick actions are personalized for known visitors
(e.g., sending a personalized greeting or instructions, taking a
message, and/or asking for a passcode). In some implementations, at
least a subset of the quick actions are specific to a type of
building (e.g. a house, condominium, apartment building, and/or a
workplace). In some implementations, at least a subset of the quick
actions are specific to a smart home user's situation and/or
temperament, such as whether the smart home user is home (e.g.,
alone) or away, or whether the user does not currently feel safe
(e.g., has been receiving threats). For example, if the smart home
user is currently feeling unsafe the system provides more
security-oriented actions, whereas if the smart home user is
feeling safe the system provides more greetings-based actions.
[0071] In some implementations, the electronic greeting system
includes a do-not-disturb mode, during which alerts are limited. In
some implementations, alerts are limited by muting (or decreasing
the volume of) a doorbell sound effect inside the home, while still
sending alerts or other notifications to a client device. In some
implementations, independent of whether an internal doorbell sound
is played, an external doorbell sound is played to give the visitor
feedback that the doorbell has been pressed. In some
implementations, the system provides visual feedback to the user
(e.g., a spinning wheel or a preprogrammed message on a display
mounted near, or integrated with, the doorbell). In some
implementations, alerts are limited by silencing alerts sent to the
client device. In some implementations, while in do-not-disturb
mode, the electronic greeting system (e.g., through an assistant)
asks the visitor if the visit is important. If so, the system sends
a corresponding alert to the user and, optionally, ceases limiting
alerts. If not, the system informs the visitor that the user is
unavailable and asks the visitor to leave a message for the user.
It is appreciated that the system will not inform a visitor that
the user is busy or not at home if security-related contextual
information makes it imprudent to do so. In some implementations,
after determining that the user is busy, the electronic greeting
system captures an image or video clip of the visitor for reporting
to the user. In some implementations, if the visitor's face has not
remained in the camera's field of view long enough to capture a
desired image or video clip (e.g., an image or video clip showing
am unobstructed frontal view of the visitor's face), the system
requests that the visitor remain in front of the door for a moment
(e.g., until the system has had sufficient time to capture an image
or video clip). In some implementations, when the user engages the
electronic greeting system after a visitor occurred, the system
provides a report to the user regarding the visit.
[0072] In some implementations, the electronic greeting system is
selectively coupled to the smart home environment via two or more
communication channels (e.g., via WiFi and Bluetooth). For example,
when the smart home WiFi is interrupted, the greeting system
switches to a backup network, such as Bluetooth.
[0073] In some implementations, the electronic greeting system
includes a camera mounted near or integrated with a doorbell
device. Additionally or alternatively, the electronic greeting
system includes a camera mounted at a higher position (e.g., 5 ft,
6 ft, or 8 ft high) in order to have a better view of the visitor's
face.
[0074] In some implementations, the electronic greeting system
detects knocking by sensing for a sequence of knocks. In some
implementations, while detecting knocks, the system accommodates
for different door materials and/or types (e.g., wood, metal, front
door, back door). In some implementations, while detecting knocks,
the system accommodates for ambient noise from the environment
surrounding the entryway. In some implementations, the system only
senses for knocking upon a determination that a visitor is
approaching. In some implementations, upon detection of a knock,
the system rings the doorbell, sends a corresponding notification
to the client device, and/or captures an image or video clip of the
visitor.
[0075] Turning now to the figures, FIG. 1 is an example smart home
environment 100 in accordance with some implementations. The smart
home environment 100 includes a structure 150 (e.g., a house,
office building, garage, or mobile home) with various integrated
devices. It will be appreciated that devices may also be integrated
into a smart home environment 100 that does not include an entire
structure 150, such as an apartment, condominium, or office space.
Further, the smart home environment 100 may control and/or be
coupled to devices outside of the actual structure 150. Indeed,
several devices in the smart home environment 100 need not be
physically within the structure 150. For example, a device
controlling a pool heater 114 or irrigation system 116 may be
located outside of the structure 150.
[0076] It is to be appreciated that "smart home environments" may
refer to smart environments for homes such as a single-family
house, but the scope of the present teachings is not so limited.
The present teachings are also applicable, without limitation, to
duplexes, townhomes, multi-unit apartment buildings, hotels, retail
stores, office buildings, industrial buildings, and more generally
any living space or work space.
[0077] It is also to be appreciated that while the terms user,
customer, installer, homeowner, occupant, guest, tenant, landlord,
repair person, and the like may be used to refer to the person or
persons acting in the context of some particularly situations
described herein, these references do not limit the scope of the
present teachings with respect to the person or persons who are
performing such actions. Thus, for example, the terms user,
customer, purchaser, installer, subscriber, and homeowner may often
refer to the same person in the case of a single-family residential
dwelling, because the head of the household is often the person who
makes the purchasing decision, buys the unit, and installs and
configures the unit, and is also one of the users of the unit.
However, in other scenarios, such as a landlord-tenant environment,
the customer may be the landlord with respect to purchasing the
unit, the installer may be a local apartment supervisor, a first
user may be the tenant, and a second user may again be the landlord
with respect to remote control functionality. Importantly, while
the identity of the person performing the action may be germane to
a particular advantage provided by one or more of the
implementations, such identity should not be construed in the
descriptions that follow as necessarily limiting the scope of the
present teachings to those particular individuals having those
particular identities.
[0078] The depicted structure 150 includes a plurality of rooms
152, separated at least partly from each other via walls 154. The
walls 154 may include interior walls or exterior walls. Each room
may further include a floor 156 and a ceiling 158. Devices may be
mounted on, integrated with and/or supported by a wall 154, floor
156 or ceiling 158.
[0079] In some implementations, the integrated devices of the smart
home environment 100 include intelligent, multi-sensing,
network-connected devices that integrate seamlessly with each other
in a smart home network (e.g., 202 FIG. 2A) and/or with a central
server or a cloud-computing system to provide a variety of useful
smart home functions. The smart home environment 100 may include
one or more intelligent, multi-sensing, network-connected
thermostats 102 (hereinafter referred to as "smart thermostats
102"), one or more intelligent, network-connected, multi-sensing
hazard detection units 104 (hereinafter referred to as "smart
hazard detectors 104"), one or more intelligent, multi-sensing,
network-connected entryway interface devices 106 and 120
(hereinafter referred to as "smart doorbells 106" and "smart door
locks 120"), and one or more intelligent, multi-sensing,
network-connected alarm systems 122 (hereinafter referred to as
"smart alarm systems 122").
[0080] In some implementations, the one or more smart thermostats
102 detect ambient climate characteristics (e.g., temperature
and/or humidity) and control a HVAC system 103 accordingly. For
example, a respective smart thermostat 102 includes an ambient
temperature sensor.
[0081] The one or more smart hazard detectors 104 may include
thermal radiation sensors directed at respective heat sources
(e.g., a stove, oven, other appliances, a fireplace, etc.). For
example, a smart hazard detector 104 in a kitchen 153 includes a
thermal radiation sensor directed at a stove/oven 112. A thermal
radiation sensor may determine the temperature of the respective
heat source (or a portion thereof) at which it is directed and may
provide corresponding blackbody radiation data as output.
[0082] The smart doorbell 106 and/or the smart door lock 120 may
detect a person's approach to or departure from a location (e.g.,
an outer door), control doorbell/door locking functionality (e.g.,
receive user inputs from a portable electronic device 166 to
actuate bolt of the smart door lock 120), announce a person's
approach or departure via audio or visual means, and/or control
settings on a security system (e.g., to activate or deactivate the
security system when occupants go and come). In some
implementations, the smart doorbell 106 includes some or all of the
components and features of the camera 118. In some implementations,
the smart doorbell 106 includes a camera 118. In some
implementations, the smart doorbell 106 includes a camera 118 that
is embedded in the doorbell 106. In some implementations, the smart
doorbell 106 includes a camera that is mounted on or near the
doorbell 106. In some implementations, the smart doorbell 106
includes a camera 118 that is not mounted in, on, or near the
doorbell 106, but is instead mounted in proximity to the doorbell
106. In some implementations, the smart doorbell 106 includes two
or more cameras 118 (e.g., one camera facing the entryway, and
another camera facing approaching visitors). In some
implementations, the smart doorbell 106 has a camera (also
sometimes referred to herein as doorbell camera 106) which is
separate from a video camera 118. For the purposes of this
disclosure, video-related references to doorbell 106 refer to one
or more cameras associated with doorbell 106.
[0083] The smart alarm system 122 may detect the presence of an
individual within close proximity (e.g., using built-in IR
sensors), sound an alarm (e.g., through a built-in speaker, or by
sending commands to one or more external speakers), and send
notifications to entities or users within/outside of the smart home
network 100. In some implementations, the smart alarm system 122
also includes one or more input devices or sensors (e.g., keypad,
biometric scanner, NFC transceiver, microphone) for verifying the
identity of a user, and one or more output devices (e.g., display,
speaker). In some implementations, the smart alarm system 122 may
also be set to an "armed" mode, such that detection of a trigger
condition or event causes the alarm to be sounded unless a
disarming action is performed.
[0084] In some implementations, the smart home environment 100
includes one or more intelligent, multi-sensing, network-connected
wall switches 108 (hereinafter referred to as "smart wall switches
108"), along with one or more intelligent, multi-sensing,
network-connected wall plug interfaces 110 (hereinafter referred to
as "smart wall plugs 110"). The smart wall switches 108 may detect
ambient lighting conditions, detect room-occupancy states, and
control a power and/or dim state of one or more lights. In some
instances, smart wall switches 108 may also control a power state
or speed of a fan, such as a ceiling fan. The smart wall plugs 110
may detect occupancy of a room or enclosure and control supply of
power to one or more wall plugs (e.g., such that power is not
supplied to the plug if nobody is at home).
[0085] In some implementations, the smart home environment 100 of
FIG. 1 includes a plurality of intelligent, multi-sensing,
network-connected appliances 112 (hereinafter referred to as "smart
appliances 112"), such as refrigerators, stoves, ovens,
televisions, washers, dryers, lights, stereos, intercom systems,
garage-door openers, floor fans, ceiling fans, wall air
conditioners, pool heaters, irrigation systems, security systems,
space heaters, window AC units, motorized duct vents, and so forth.
In some implementations, when plugged in, an appliance may announce
itself to the smart home network, such as by indicating what type
of appliance it is, and it may automatically integrate with the
controls of the smart home. Such communication by the appliance to
the smart home may be facilitated by either a wired or wireless
communication protocol. The smart home may also include a variety
of non-communicating legacy appliances 140, such as old
conventional washer/dryers, refrigerators, and the like, which may
be controlled by smart wall plugs 110. The smart home environment
100 may further include a variety of partially communicating legacy
appliances 142, such as infrared ("IR") controlled wall air
conditioners or other IR-controlled devices, which may be
controlled by IR signals provided by the smart hazard detectors 104
or the smart wall switches 108.
[0086] In some implementations, the smart home environment 100
includes one or more network-connected cameras 118 that are
configured to provide video monitoring and security in the smart
home environment 100. The cameras 118 may be used to determine
occupancy of the structure 150 and/or particular rooms 152 in the
structure 150, and thus may act as occupancy sensors. For example,
video captured by the cameras 118 may be processed to identify the
presence of an occupant in the structure 150 (e.g., in a particular
room 152). Specific individuals may be identified based, for
example, on their appearance (e.g., height, face) and/or movement
(e.g., their walk/gait). Cameras 118 may additionally include one
or more sensors (e.g., IR sensors, motion detectors), input devices
(e.g., microphone for capturing audio), and output devices (e.g.,
speaker for outputting audio). In some implementations, the cameras
118 are each configured to operate in a day mode and in a low-light
mode (e.g., a night mode). In some implementations, the cameras 118
each include one or more IR illuminators for providing illumination
while the camera is operating in the low-light mode. In some
implementations, the cameras 118 include one or more outdoor
cameras. In some implementations, the outdoor cameras include
additional features and/or components such as weatherproofing
and/or solar ray compensation.
[0087] In some implementations, the smart home environment 100
includes one or more network-connected doorbells 106 that are
configured to provide video monitoring and security in a vicinity
of an entryway of the smart home environment 100. The doorbells 106
are optionally used to determine the approach and/or presence of a
visitor. Specific individuals are optionally identified based, for
example, on their appearance (e.g., height, face) and/or movement
(e.g., their walk/gait). A doorbell 106 optionally includes one or
more sensors (e.g., IR sensors, motion detectors), input devices
(e.g., microphone for capturing audio), and output devices (e.g.,
speaker for outputting audio). In some implementations, a doorbell
106 is configured to operate in a high-light mode (e.g., a day
mode) and in a low-light mode (e.g., a night mode). In some
implementations, a doorbell 106 includes one or more IR
illuminators for providing illumination while the camera is
operating in the low-light mode. In some implementations, a
doorbell 106 includes one or more lights (e.g., one or more LEDs)
for illuminating the doorbell in low-light conditions and/or giving
visual feedback to a visitor. In some implementations, a doorbell
106 includes additional features and/or components such as
weatherproofing and/or solar ray compensation. In some
implementations, doorbell 106 is battery powered and runs in a low
power or a high-power mode. In some implementations, in the low
power mode, doorbell 106 detects an approaching visitor using a low
power sensors such as a PIR sensor which is always on or
periodically on. In some implementations, after the visitor
approach is detected, doorbell 106 switches to the high power mode
to carry out further processing functions (described below).
[0088] In some implementations, the smart home environment 100
additionally or alternatively includes one or more other occupancy
sensors (e.g., the smart doorbell 106, smart door locks 120, touch
screens, IR sensors, microphones, ambient light sensors, motion
detectors, smart nightlights 170, etc.). In some implementations,
the smart home environment 100 includes radio-frequency
identification (RFID) readers (e.g., in each room 152 or a portion
thereof) that determine occupancy based on RFID tags located on or
embedded in occupants. For example, RFID readers may be integrated
into the smart hazard detectors 104.
[0089] In some implementations, the smart home environment 100
includes one or more devices outside of the physical home but
within a proximate geographical range of the home. For example, the
smart home environment 100 may include a pool heater monitor 114
that communicates a current pool temperature to other devices
within the smart home environment 100 and/or receives commands for
controlling the pool temperature. Similarly, the smart home
environment 100 may include an irrigation monitor 116 that
communicates information regarding irrigation systems within the
smart home environment 100 and/or receives control information for
controlling such irrigation systems.
[0090] By virtue of network connectivity, one or more of the smart
home devices of FIG. 1 may further allow a user to interact with
the device even if the user is not proximate to the device. For
example, a user may communicate with a device using a computer
(e.g., a desktop computer, laptop computer, or tablet) or other
portable electronic device 166 (e.g., a mobile phone, such as a
smart phone). A webpage or application may be configured to receive
communications from the user and control the device based on the
communications and/or to present information about the device's
operation to the user. For example, the user may view a current set
point temperature for a device (e.g., a stove) and adjust it using
a computer. The user may be in the structure during this remote
communication or outside the structure.
[0091] As discussed above, users may control smart devices in the
smart home environment 100 using a network-connected computer or
portable electronic device 166. In some examples, some or all of
the occupants (e.g., individuals who live in the home) may register
their device 166 with the smart home environment 100. Such
registration may be made at a central server to authenticate the
occupant and/or the device as being associated with the home and to
give permission to the occupant to use the device to control the
smart devices in the home. An occupant may use their registered
device 166 to remotely control the smart devices of the home, such
as when the occupant is at work or on vacation. The occupant may
also use their registered device to control the smart devices when
the occupant is actually located inside the home, such as when the
occupant is sitting on a couch inside the home. It should be
appreciated that instead of or in addition to registering devices
166, the smart home environment 100 may make inferences about which
individuals live in the home and are therefore occupants and which
devices 166 are associated with those individuals. As such, the
smart home environment may "learn" who is an occupant and permit
the devices 166 associated with those individuals to control the
smart devices of the home.
[0092] In some implementations, in addition to containing
processing and sensing capabilities, devices 102, 104, 106, 108,
110, 112, 114, 116, 118, 120, and/or 122 (collectively referred to
as "the smart devices") are capable of data communications and
information sharing with other smart devices, a central server or
cloud-computing system, and/or other devices that are
network-connected. Data communications may be carried out using any
of a variety of custom or standard wireless protocols (e.g., IEEE
802.15.4, Wi-Fi, ZigBee, 6LoWPAN, Thread, Z-Wave, Bluetooth Smart,
ISA100.5A, WirelessHART, MiWi, etc.) and/or any of a variety of
custom or standard wired protocols (e.g., Ethernet, HomePlug,
etc.), or any other suitable communication protocol, including
communication protocols not yet developed as of the filing date of
this document.
[0093] In some implementations, the smart devices serve as wireless
or wired repeaters. In some implementations, a first one of the
smart devices communicates with a second one of the smart devices
via a wireless router. The smart devices may further communicate
with each other via a connection (e.g., network interface 160) to a
network, such as the Internet 162. Through the Internet 162, the
smart devices may communicate with a server system 164 (also called
a central server system and/or a cloud-computing system herein).
The server system 164 may be associated with a manufacturer,
support entity, or service provider associated with the smart
device(s). In some implementations, a user is able to contact
customer support using a smart device itself rather than needing to
use other communication means, such as a telephone or
Internet-connected computer. In some implementations, software
updates are automatically sent from the server system 164 to smart
devices (e.g., when available, when purchased, or at routine
intervals).
[0094] In some implementations, the network interface 160 includes
a conventional network device (e.g., a router), and the smart home
environment 100 of FIG. 1 includes a hub device 180 that is
communicatively coupled to the network(s) 162 directly or via the
network interface 160. The hub device 180 is further
communicatively coupled to one or more of the above intelligent,
multi-sensing, network-connected devices (e.g., smart devices of
the smart home environment 100). Each of these smart devices
optionally communicates with the hub device 180 using one or more
radio communication networks available at least in the smart home
environment 100 (e.g., ZigBee, Z-Wave, Insteon, Bluetooth, Wi-Fi
and other radio communication networks). In some implementations,
the hub device 180 and devices coupled with/to the hub device can
be controlled and/or interacted with via an application running on
a smart phone, household controller, laptop, tablet computer, game
console or similar electronic device. In some implementations, a
user of such controller application can view status of the hub
device or coupled smart devices, configure the hub device to
interoperate with smart devices newly introduced to the home
network, commission new smart devices, and adjust or view settings
of connected smart devices, etc. In some implementations the hub
device extends capabilities of low capability smart device to match
capabilities of the highly capable smart devices of the same type,
integrates functionality of multiple different device types--even
across different communication protocols, and is configured to
streamline adding of new devices and commissioning of the hub
device. In some implementations, hub device 180 further comprises a
local storage device for storing data related to, or output by,
smart devices of smart home environment 100. In some
implementations, the data includes one or more of: video data
output by a camera device, metadata output by a smart device,
settings information for a smart device, usage logs for a smart
device, and the like.
[0095] In some implementations, smart home environment 100 includes
a local storage device 190 for storing data related to, or output
by, smart devices of smart home environment 100. In some
implementations, the data includes one or more of: video data
output by a camera device (e.g., a camera included with doorbell
106), metadata output by a smart device, settings information for a
smart device, usage logs for a smart device, and the like. In some
implementations, local storage device 190 is communicatively
coupled to one or more smart devices via a smart home network
(e.g., smart home network 202, FIG. 2A). In some implementations,
local storage device 190 is selectively coupled to one or more
smart devices via a wired and/or wireless communication network. In
some implementations, local storage device 190 is used to store
video data when external network conditions are poor. For example,
local storage device 190 is used when an encoding bitrate of the
camera included with doorbell 106 exceeds the available bandwidth
of the external network (e.g., network(s) 162). In some
implementations, local storage device 190 temporarily stores video
data from one or more doorbells (e.g., doorbell 106) prior to
transferring the video data to a server system (e.g., server system
164).
[0096] FIG. 2A is a block diagram illustrating a representative
network architecture 200 that includes a smart home network 202 in
accordance with some implementations. In some implementations, the
smart devices 204 in the smart home environment 100 (e.g., devices
102, 104, 106, 108, 110, 112, 114, 116, 118, 120, and/or 122)
combine with the hub device 180 to create a mesh network in smart
home network 202. In some implementations, one or more smart
devices 204 in the smart home network 202 operate as a smart home
controller. Additionally and/or alternatively, hub device 180
operates as the smart home controller. In some implementations, a
smart home controller has more computing power than other smart
devices. In some implementations, a smart home controller processes
inputs (e.g., from smart devices 204, electronic device 166, and/or
server system 164) and sends commands (e.g., to smart devices 204
in the smart home network 202) to control operation of the smart
home environment 100. In some implementations, some of the smart
devices 204 in the smart home network 202 (e.g., in the mesh
network) are "spokesman" nodes (e.g., 204-1) and others are
"low-powered" nodes (e.g., 204-9). Some of the smart devices in the
smart home environment 100 are battery powered, while others have a
regular and reliable power source, such as by connecting to wiring
(e.g., to 120V line voltage wires) behind the walls 154 of the
smart home environment. The smart devices that have a regular and
reliable power source are referred to as "spokesman" nodes. These
nodes are typically equipped with the capability of using a
wireless protocol to facilitate bidirectional communication with a
variety of other devices in the smart home environment 100, as well
as with the server system 164. In some implementations, one or more
"spokesman" nodes operate as a smart home controller. On the other
hand, the devices that are battery powered are the "low-power"
nodes. These nodes tend to be smaller than spokesman nodes and
typically only communicate using wireless protocols that require
very little power, such as Zigbee, ZWave, 6LoWPAN, Thread,
Bluetooth, etc.
[0097] In some implementations, some low-power nodes are incapable
of bidirectional communication. These low-power nodes send
messages, but they are unable to "listen". Thus, other devices in
the smart home environment 100, such as the spokesman nodes, cannot
send information to these low-power nodes.
[0098] In some implementations, some low-power nodes are capable of
only a limited bidirectional communication. For example, other
devices are able to communicate with the low-power nodes only
during a certain time period.
[0099] As described, in some implementations, the smart devices
serve as low-power and spokesman nodes to create a mesh network in
the smart home environment 100. In some implementations, individual
low-power nodes in the smart home environment regularly send out
messages regarding what they are sensing, and the other low-powered
nodes in the smart home environment--in addition to sending out
their own messages--forward the messages, thereby causing the
messages to travel from node to node (i.e., device to device)
throughout the smart home network 202. In some implementations, the
spokesman nodes in the smart home network 202, which are able to
communicate using a relatively high-power communication protocol,
such as IEEE 802.11, are able to switch to a relatively low-power
communication protocol, such as IEEE 802.15.4, to receive these
messages, translate the messages to other communication protocols,
and send the translated messages to other spokesman nodes and/or
the server system 164 (using, e.g., the relatively high-power
communication protocol). Thus, the low-powered nodes using
low-power communication protocols are able to send and/or receive
messages across the entire smart home network 202, as well as over
the Internet 162 to the server system 164. In some implementations,
the mesh network enables the server system 164 to regularly receive
data from most or all of the smart devices in the home, make
inferences based on the data, facilitate state synchronization
across devices within and outside of the smart home network 202,
and send commands to one or more of the smart devices to perform
tasks in the smart home environment.
[0100] As described, the spokesman nodes and some of the
low-powered nodes are capable of "listening." Accordingly, users,
other devices, and/or the server system 164 may communicate control
commands to the low-powered nodes. For example, a user may use the
electronic device 166 (e.g., a smart phone) to send commands over
the Internet to the server system 164, which then relays the
commands to one or more spokesman nodes in the smart home network
202. The spokesman nodes may use a low-power protocol to
communicate the commands to the low-power nodes throughout the
smart home network 202, as well as to other spokesman nodes that
did not receive the commands directly from the server system
164.
[0101] In some implementations, a smart nightlight 170 (FIG. 1),
which is an example of a smart device 204, is a low-power node. In
addition to housing a light source, the smart nightlight 170 houses
an occupancy sensor, such as an ultrasonic or passive IR sensor,
and an ambient light sensor, such as a photo resistor or a
single-pixel sensor that measures light in the room. In some
implementations, the smart nightlight 170 is configured to activate
the light source when its ambient light sensor detects that the
room is dark and when its occupancy sensor detects that someone is
in the room. In other implementations, the smart nightlight 170 is
simply configured to activate the light source when its ambient
light sensor detects that the room is dark. Further, in some
implementations, the smart nightlight 170 includes a low-power
wireless communication chip (e.g., a ZigBee chip) that regularly
sends out messages regarding the occupancy of the room and the
amount of light in the room, including instantaneous messages
coincident with the occupancy sensor detecting the presence of a
person in the room. As mentioned above, these messages may be sent
wirelessly (e.g., using the mesh network) from node to node (i.e.,
smart device to smart device) within the smart home network 202 as
well as over the Internet 162 to the server system 164.
[0102] Other examples of low-power nodes include battery-operated
versions of the smart hazard detectors 104. These smart hazard
detectors 104 are often located in an area without access to
constant and reliable power and may include any number and type of
sensors, such as smoke/fire/heat sensors (e.g., thermal radiation
sensors), carbon monoxide/dioxide sensors, occupancy/motion
sensors, ambient light sensors, ambient temperature sensors,
humidity sensors, and the like. Furthermore, smart hazard detectors
104 may send messages that correspond to each of the respective
sensors to the other devices and/or the server system 164, such as
by using the mesh network as described above.
[0103] Examples of spokesman nodes include smart doorbells 106,
smart thermostats 102, smart wall switches 108, and smart wall
plugs 110. These devices are often located near and connected to a
reliable power source, and therefore may include more
power-consuming components, such as one or more communication chips
capable of bidirectional communication in a variety of
protocols.
[0104] In some implementations, the smart home environment 100
includes service robots 168 (FIG. 1) that are configured to carry
out, in an autonomous manner, any of a variety of household
tasks.
[0105] As explained above with reference to FIG. 1, in some
implementations, the smart home environment 100 of FIG. 1 includes
a hub device 180 that is communicatively coupled to the network(s)
162 directly or via the network interface 160. The hub device 180
is further communicatively coupled to one or more of the smart
devices using a radio communication network that is available at
least in the smart home environment 100. Communication protocols
used by the radio communication network include, but are not
limited to, ZigBee, Z-Wave, Insteon, EuOcean, Thread, OSIAN,
Bluetooth Low Energy and the like. In some implementations, the hub
device 180 not only converts the data received from each smart
device to meet the data format requirements of the network
interface 160 or the network(s) 162, but also converts information
received from the network interface 160 or the network(s) 162 to
meet the data format requirements of the respective communication
protocol associated with a targeted smart device. In some
implementations, in addition to data format conversion, the hub
device 180 further processes the data received from the smart
devices or information received from the network interface 160 or
the network(s) 162 preliminary. For example, the hub device 180 can
integrate inputs from multiple sensors/connected devices (including
sensors/devices of the same and/or different types), perform higher
level processing on those inputs--e.g., to assess the overall
environment and coordinate operation among the different
sensors/devices--and/or provide instructions to the different
devices based on the collection of inputs and programmed
processing. It is also noted that in some implementations, the
network interface 160 and the hub device 180 are integrated to one
network device. Functionality described herein is representative of
particular implementations of smart devices, control application(s)
running on representative electronic device(s) (such as a smart
phone), hub device(s) 180, and server(s) coupled to hub device(s)
via the Internet or other Wide Area Network. All or a portion of
this functionality and associated operations can be performed by
any elements of the described system--for example, all or a portion
of the functionality described herein as being performed by an
implementation of the hub device can be performed, in different
system implementations, in whole or in part on the server, one or
more connected smart devices and/or the control application, or
different combinations thereof.
[0106] FIG. 2B illustrates a representative operating environment
in which a server system 164 provides data processing for
monitoring and facilitating review of events (e.g., motion, audio,
security, etc.) in video streams captured by video cameras 118 or
doorbell cameras 106. As shown in FIG. 2B, the server system 164
receives video data from video sources 222 (including cameras 118
or doorbell cameras 106) located at various physical locations
(e.g., inside or in proximity to homes, restaurants, stores,
streets, parking lots, and/or the smart home environments 100 of
FIG. 1). Each video source 222 may be bound to one or more reviewer
accounts, and the server system 164 provides video monitoring data
for the video source 222 to client devices 220 associated with the
reviewer accounts. For example, the portable electronic device 166
is an example of the client device 220. In some implementations,
the server system 164 is a video processing server that provides
video processing services to the video sources and client devices
220.
[0107] In some implementations, each of the video sources 222
includes one or more video cameras 118 or doorbell cameras 106 that
capture video and send the captured video to the server system 164
substantially in real-time. In some implementations, each of the
video sources 222 includes one or more doorbell cameras 106 that
capture video and send the captured video to the server system 164
in real-time (e.g., within 1 second, 10 seconds, 30 seconds, or 1
minute). In some implementations, each of the doorbells 106 include
a video camera that captures video and sends the captured video to
the server system 164 in real-time. In some implementations, a
video source 222 includes a controller device (not shown) that
serves as an intermediary between the one or more doorbells 106 and
the server system 164. The controller device receives the video
data from the one or more doorbells 106, optionally performs some
preliminary processing on the video data, and sends the video data
and/or the results of the preliminary processing to the server
system 164 on behalf of the one or more doorbells 106 (e.g., in
real-time). In some implementations, each camera has its own
on-board processing capabilities to perform some preliminary
processing on the captured video data before sending the video data
(e.g., along with metadata obtained through the preliminary
processing) to the controller device and/or the server system
164.
[0108] In accordance with some implementations, a client device 220
includes a client-side module, such as client-side module 628 in
FIG. 6. In some implementations, the client-side module
communicates with a server-side module executed on the server
system 164 through the one or more networks 162. The client-side
module provides client-side functionality for the event monitoring
and review processing and communications with the server-side
module. The server-side module provides server-side functionality
for event monitoring and review processing for any number of
client-side modules each residing on a respective client device
220. In some implementations, the server-side module also provides
server-side functionality for video processing and camera control
for any number of the video sources 222, including any number of
control devices, cameras 118, and doorbells 106.
[0109] In some implementations, the server system 164 includes one
or more processors 212, a video storage database 210, an account
database 214, an I/O interface to one or more client devices 216,
and an I/O interface to one or more video sources 218. The I/O
interface to one or more clients 216 facilitates the client-facing
input and output processing. The account database 214 stores a
plurality of profiles for reviewer accounts registered with the
video processing server, where a respective user profile includes
account credentials for a respective reviewer account, and one or
more video sources linked to the respective reviewer account. The
I/O interface to one or more video sources 218 facilitates
communications with one or more video sources 222 (e.g., groups of
one or more doorbells 106, cameras 118, and associated controller
devices). The video storage database 210 stores raw video data
received from the video sources 222, as well as various types of
metadata, such as motion events, event categories, event category
models, event filters, and event masks, for use in data processing
for event monitoring and review for each reviewer account.
[0110] Examples of a representative client device 220 include a
handheld computer, a wearable computing device, a personal digital
assistant (PDA), a tablet computer, a laptop computer, a desktop
computer, a cellular telephone, a smart phone, an enhanced general
packet radio service (EGPRS) mobile phone, a media player, a
navigation device, a game console, a television, a remote control,
a point-of-sale (POS) terminal, a vehicle-mounted computer, an
eBook reader, or a combination of any two or more of these data
processing devices or other data processing devices.
[0111] Examples of the one or more networks 162 include local area
networks (LAN) and wide area networks (WAN) such as the Internet.
The one or more networks 162 are implemented using any known
network protocol, including various wired or wireless protocols,
such as Ethernet, Universal Serial Bus (USB), FIREWIRE, Long Term
Evolution (LTE), Global System for Mobile Communications (GSM),
Enhanced Data GSM Environment (EDGE), code division multiple access
(CDMA), time division multiple access (TDMA), Bluetooth, Wi-Fi,
voice over Internet Protocol (VoIP), Wi-MAX, or any other suitable
communication protocol.
[0112] In some implementations, the server system 164 is
implemented on one or more standalone data processing apparatuses
or a distributed network of computers. In some implementations, the
server system 164 also employs various virtual devices and/or
services of third-party service providers (e.g., third-party cloud
service providers) to provide the underlying computing resources
and/or infrastructure resources of the server system 164. In some
implementations, the server system 164 includes, but is not limited
to, a server computer, a handheld computer, a tablet computer, a
laptop computer, a desktop computer, or a combination of any two or
more of these data processing devices or other data processing
devices.
[0113] The server-client environment shown in FIG. 2B includes both
a client-side portion (e.g., the client-side module) and a
server-side portion (e.g., the server-side module). The division of
functionality between the client and server portions of operating
environment can vary in different implementations. Similarly, the
division of functionality between a video source 222 and the server
system 164 can vary in different implementations. For example, in
some implementations, the client-side module is a thin-client that
provides only user-facing input and output processing functions,
and delegates all other data processing functionality to a backend
server (e.g., the server system 164). Similarly, in some
implementations, a respective one of the video sources 222 is a
simple video capturing device that continuously captures and
streams video data to the server system 164 with limited or no
local preliminary processing on the video data. Although many
aspects of the present technology are described from the
perspective of the server system 164, the corresponding actions
performed by a client device 220 and/or the video sources 222 would
be apparent to one of skill in the art. Similarly, some aspects of
the present technology may be described from the perspective of a
client device or a video source, and the corresponding actions
performed by the video server would be apparent to one of skill in
the art. Furthermore, some aspects of the present technology may be
performed by the server system 164, a client device 220, and a
video source 222 cooperatively.
[0114] In some implementations, a video source 222 (e.g., a camera
118 or doorbell 106 having an image sensor) transmits one or more
streams of video data to the server system 164. In some
implementations, the one or more streams include multiple streams,
of respective resolutions and/or frame rates, of the raw video
captured by the image sensor. In some implementations, the multiple
streams include a "primary" stream (e.g., 226-1) with a certain
resolution and frame rate, corresponding to the raw video captured
by the image sensor, and one or more additional streams (e.g.,
226-2 through 226-q). An additional stream is optionally the same
video stream as the "primary" stream but at a different resolution
and/or frame rate, or a stream that captures a portion of the
"primary" stream (e.g., cropped to include a portion of the field
of view or pixels of the primary stream) at the same or different
resolution and/or frame rate as the "primary" stream.
[0115] In some implementations, one or more of the streams 226 is
sent from the video source 222 directly to a client device 220
(e.g., without being routed to, or processed by, the server system
164). In some implementations, one or more of the streams is stored
at the doorbell 106 (e.g., in memory 406, FIG. 4) and/or a local
storage device (e.g., a dedicated recording device), such as a
digital video recorder (DVR). For example, in accordance with some
implementations, the doorbell 106 stores the most recent 24 hours
of video footage recorded by the camera. In some implementations,
portions of the one or more streams are stored at the doorbell 106
and/or the local storage device (e.g., portions corresponding to
particular events or times of interest).
[0116] In some implementations, the server system 164 transmits one
or more streams of video data to a client device 220 to facilitate
event monitoring by a user. In some implementations, the one or
more streams may include multiple streams, of respective
resolutions and/or frame rates, of the same video feed. In some
implementations, the multiple streams include a "primary" stream
with a certain resolution and frame rate, corresponding to the
video feed, and one or more additional streams. An additional
stream may be the same video stream as the "primary" stream but at
a different resolution and/or frame rate, or a stream that shows a
portion of the "primary" stream (e.g., cropped to include portion
of the field of view or pixels of the primary stream) at the same
or different resolution and/or frame rate as the "primary" stream,
as described in greater detail in U.S. patent application Ser. No.
15/594,518.
[0117] FIG. 3A is a block diagram illustrating the server system
164 in accordance with some implementations. The server system 164
typically includes one or more processing units (CPUs) 302, one or
more network interfaces 304 (e.g., including an I/O interface to
one or more client devices and an I/O interface to one or more

from client devices 220) and forwarding user-initiated control
commands to modify operation modes of the electronic devices;
[0123] a data processing module 3144 for processing the data
provided by the electronic devices, and/or preparing and sending
processed data to a device for review (e.g., client devices 220 for
review by a user), including, but not limited to: [0124] a video
processor sub-module 3146 for processing (e.g., categorizing and/or
recognizing) detected entities and/or event candidates within a
received video stream (e.g., a video stream from doorbell 106); and
[0125] a user interface sub-module 3150 for communicating with a
user (e.g., sending alerts, timeline events, etc. and receiving
user edits and zone definitions and the like); and [0126] a server
database 316, including but not limited to: [0127] a data storage
database 3160 for storing data associated with each electronic

device, creation time, duration, settings of the electronic device,
etc.) associated with the data, where (optionally) all or a portion
of the data and/or processing associated with the hub device 180 or
smart devices are stored securely; [0128] an account database 3162
for storing account information for user accounts, including user
account information such as user profiles 3163, information and
settings for linked hub devices and electronic devices (e.g., hub
device identifications), hub device specific secrets, relevant user
and hardware characteristics (e.g., service tier, device model,
storage capacity, processing capabilities, etc.), user interface
settings, data review preferences, etc., where the information for
associated electronic devices includes, but is not limited to, one
or more device identifiers (e.g., MAC address and UUID), device
specific secrets, and displayed titles; [0129] a device information
database 3164 for storing device information related to one or more
devices such as device profiles 3165, e.g., device identifiers and
hub device specific secrets, independently of whether the
corresponding hub devices have been associated with any user
account; [0130] an event information database 3166 for storing
event information such as context information 31686, e.g.,
contextual data describing circumstances surrounding an approaching
visitor; and [0131] a person's database 3180 for storing
information regarding detected and/or recognized persons, such as
images (e.g., cropped headshots) 3182 of detected persons and
feature characterization data 3184 for the persons.
[0132] Each of the above identified elements may be stored in one
or more of the previously mentioned memory devices, and corresponds
to a set of instructions for performing a function described above.
The above identified modules or programs (i.e., sets of
instructions) need not be implemented as separate software
programs, procedures, or modules, and thus various subsets of these
modules may be combined or otherwise rearranged in various
implementations. In some implementations, the memory 306,
optionally, stores a subset of the modules and data structures
identified above. Furthermore, the memory 306, optionally, stores
additional modules and data structures not described above.
[0133] FIG. 3B illustrates various data structures used by some
implementations, including an event record 3168-i, a user profile
3163-j, a device profile 3165-k, and characterization data 3184-m.
The event record 3168-i corresponds to an event T and data for the
event T. In some implementations, the event T includes one or more
of: a motion event, a hazard event, an audio event, and a security
event. In some instances, the data for a motion event T includes
event start data 31681 indicating when and/or how the event
started, event segments data 31682, raw video data 31683, event end
data 31684 indicating when and/or how the event ended, event
features data 31685, context information data 31686, associated
user information 31687, and associated devices information 31688.
In some instances, the event record 3168-i includes only a subset
of the above data. In some instances, the event record 3168-i
includes additional event data not shown such as data regarding
event/motion masks.
[0134] The event start data 31681 includes date and time
information such as a timestamp and optionally includes additional
information such as information regarding the amount of motion
present, a motion start location, amount of audio present,
characteristics of the audio, and the like. Similarly, the event
end data 31684 includes date and time information such as a
timestamp and optionally includes additional information such as
information regarding the amount of motion present, a motion start
location, amount of audio present, characteristics of the audio,
and the like.
[0135] The event segments 31682 includes information regarding
segmentation of the motion event T. In some instances, event
segments are stored separately from the raw video data 31683. In
some instances, the event segments are stored at a lower display
resolution than the raw video data. For example, the event segments
are optionally stored at 480p or 780p and the raw video data is
stored at 1080i or 1080p. Storing the event segments at a lower
display resolution enables the system to devote less time and
resources to retrieving and processing the event segments. In some
instances, the event segments are not stored separately, and the
segmentation information includes references to the raw video data
31683 as well as date and time information for reproducing the
event segments. In some implementations, the event segments include
one or more audio segments (e.g., corresponding to video
segments).
[0136] The event features data 31685 includes information regarding
event features such as event categorizations/classifications,
object masks, motion masks, identified/recognized/tracked motion
objects (also sometimes called blobs), information regarding

information regarding the event such as information regarding the
visitor (e.g., behavior, clothing, or size characteristics),
information regarding approach timing (e.g., time of day, level of
brightness), information regarding visitor announcements (e.g.,
doorbell press, knocking, and associated timing thereof),

the associated devices information 31688 includes a link, pointer,
or reference to a device profile 3165 for the device.
[0139] The user profile 3163-j corresponds to a user T associated
with the smart home network (e.g., smart home network 202) such as
a user of a hub device 204, a user identified by a hub device 204,
a user who receives notifications from a hub device 204 or from the
server system 164, and the like. In some instances, the user
profile 3163-j includes user preferences 31631, user settings
31632, associated devices information 31633, and associated events
information 31634. In some instances, the user profile 3163-j

user profile 3163-j includes additional user information not shown,
such as information regarding other users associated with the user
`j`.
[0140] The user preferences 31631 include explicit user preferences
input by the user as well as implicit and/or inferred user
preferences determined by the system (e.g., server system 164
and/or client device 220). In some instances, the inferred user
preferences are based on historical user activity and/or historical
activity of other users. The user settings 31632 include
information regarding settings set by the user T such as
notification settings, device settings, and the like. In some
instances, the user settings 31632 include device settings for
devices associated with the user `j`.
[0141] The associated devices information 31633 includes
information regarding devices associated with the user T such as
devices within the user's smart home environment 100 and/or client
devices 220. In some instances, associated devices information

device settings 31651, associated devices information 31652,
associated user information 31653, associated event information
31654, and environmental data 31655. In some instances, the device
profile 3165-k includes only a subset of the above data. In some
instances, the device profile 3165-k includes additional device
information not shown such as information regarding whether the
device `k` is currently active.
[0143] The device settings 31651 include information regarding the
current settings of device `k` such as positioning information,
mode of operation information, and the like. In some instances, the
device settings 31651 are user-specific and are set by respective
users of the device `k`. The associated devices information 31652
includes information regarding other devices associated with device
`k` such as other devices linked to device i and/or other devices
in the same smart home network as device `k`. In some instances,
the associated devices information 31652 includes a link, pointer,
or reference to a respective device profile 3165 corresponding to
the associated device.
[0144] The associated user information 31653 includes information
regarding users associated with the device such as users receiving
notifications from the device, users registered with the device,
users associated with the smart home network of the device, and the
like. In some instances, the associated user information 31653

an event record 3168 corresponding to the associated event.
[0146] The environmental data 31655 includes information regarding
the environment of device `k` such as information regarding whether
the device is outdoors or indoors, information regarding the light
level of the environment, information regarding the amount of
activity expected in the environment (e.g., information regarding
whether the device is in a private residence versus a busy
commercial property), information regarding environmental objects
(e.g., depth mapping information for a camera), and the like.
[0147] The characterization data 3184-m corresponds to a person `m`
detected by within the smart home environment 100. In some
implementations, characterization data for persons designated as
strangers is deleted. In some implementations, characterization
data is deleted for persons who do not give consent to having their
personally identifiable information stored. As shown in FIG. 3B, in
accordance with some implementations, the characterization data
3184 includes an associated person identifier 31841, an associated
image identifier 31842, quality information 31843, pose information
31844, timing information 31845, confidence information 31846,
location information 31847, physical feature information 31848, and
behavioral information 31849. In some implementations, the
characterization data 3184 includes additional data not shown. In
some implementations, the characterization data 3184 includes only
a subset of the data shown.
[0148] The associated person identifier 31841 includes a label or
other identifier for the person represented by the characterization
data. In some implementations, the label is applied by a user upon
review of the corresponding image. In some implementations, the
identifier 31841 is assigned by the system in accordance with a
determination that the characterization data 3184 matches, or is
similar to, other characterization data associated with the
identifier.
[0149] The associated image identifier 31842 identifies one or more
images from which the characterization data 3184 was generated. In
some implementations, there is a one-to-one mapping between the
characterization data and the images, while in some other
implementations, there is a many-to-one or one-to-many mapping. In
some implementations, the associated image identifier 31842
includes a pointer or logical storage address for the one or more
images.
[0150] The quality information 31843 includes a quality factor for
the characterization data 3184. In some implementations, the
quality factor is based on one or more of: a blurriness of the
image, a resolution of the image, an amount of the person that is
visible in the image, how many features of the person are visible
in the image, and a distance between the person and the camera that
captured the image.
[0151] The pose information 31844 identifies a pose of the detected
person. In some implementations, the pose information 31844
includes information regarding an angle between the camera that
captured the image and the detected person. In some
implementations, the pose information 31844 includes information
regarding a portion of the person's face that is visible in the
image.
[0152] The timing information 31845 includes information regarding
when the image was captured by the camera. In some implementations,
the timing information 31845 indicates the time of day, the day,
the month, the year, etc. that the image was captured. In some
implementations, the characterization data 3184 includes operating
information for the camera indicating the mode of operation and
settings of the camera (e.g., indicating whether the camera was in
a low-light mode when the image was captured). In some
implementations, the timing information 31845 is used in
conjunction with a device profile 3165 for the camera to determine
operating information for the camera at the time the image was
captured.
[0153] The confidence information 31846 indicates a confidence that
the associated person identifier 31841 is accurate. In some
implementations, the confidence information 31846 is based on a
similarity between the characterization data 3184 and other
characterization data for the associated person. In some
implementations, the confidence information 31846 includes a
confidence score for the characterization data 3184. In some
implementations, in accordance with a determination that the
confidence score is below a predetermined threshold, the
association to the person is reevaluated and/or the
characterization data 3184 and associated image is flagged as
potentially having an incorrect associated person identifier 31841.
In some implementations, flagged characterization data 3184 is
presented to a user for confirmation or reclassification.
[0154] The location information 31847 includes information
regarding a location for the image and/or the detected person. In
some implementations, the location information 31847 indicates a
location for the camera that captured the image. In some
implementations, the location information 31847 identifies the
camera that captured the image. In some implementations, the
location information 31847 indicates a room or portion of the smart
home environment that was captured in the image. In some
implementations, the location information 31847 indicates a GPS or
coordinates-based location for the image.
[0155] The physical feature information 31848 includes information
regarding the physical features of the detected person. In some
implementations, the physical feature information 31848 includes
characterization of the person's physical features (e.g., nose,
ears, eyes, and hair). In some implementations, the physical
feature information 31848 includes information regarding the
person's speech, gait, and/or posture. In some implementations, the
physical feature information 31848 includes information regarding
the person's dimensions, such as the distance between the person's
eyes or ears, or the length of the person's arms or legs. In some
implementations, the physical feature information 31848 includes
information regarding of the person's age, gender, and/or
ethnicity. In some implementations, the physical feature
information 31848 includes information regarding the person's
clothing and/or accessories (e.g., whether the person is wearing a
hat, glass, gloves, and/or rings).
[0156] The behavioral information 31849 includes information
regarding the behavior of the detected person. In some
implementations, the behavioral information 31849 includes
information regarding the detected person's mood and/or
mannerisms.

facilitate user input such as a keyboard, a mouse, a voice-command
input unit or microphone, a touch screen display, a touch-sensitive
input pad, a gesture capturing camera, or other input buttons or
controls. In some implementations, an input device 414 for a
doorbell 106 is a tactile or touch-sensitive doorbell button.
Furthermore, some smart devices 204 use a microphone and voice
recognition or a camera and gesture recognition to supplement or
replace the keyboard. In some implementations, the smart device 204
includes one or more image/video capture devices 418 (e.g.,
cameras, video cameras, scanners, photo sensor units).
[0158] The built-in sensors 490 include, for example, one or more
thermal radiation sensors, ambient temperature sensors, humidity
sensors, IR sensors, proximity sensors, range sensors, occupancy
sensors (e.g., using RFID sensors), ambient light sensors, motion
detectors, accelerometers, and/or gyroscopes.
[0159] The radios 440 enable one or more radio communication
networks in the smart home environments, and allow a smart device
204 to communicate with other devices. In some implementations, the
radios 440 are capable of data communications using any of a
variety of custom or standard wireless protocols (e.g., IEEE
802.15.4, Wi-Fi, ZigBee, 6LoWPAN, Thread, Z-Wave, Bluetooth Smart,
ISA100.5A, WirelessHART, MiWi, etc.) custom or standard wired
protocols (e.g., Ethernet, HomePlug, etc.), and/or any other
suitable communication protocol, including communication protocols
not yet developed as of the filing date of this document.
[0160] The communication interfaces 404 include, for example,

custom or standard wireless protocols (e.g., IEEE 802.15.4, Wi-Fi,
ZigBee, 6LoWPAN, Thread, Z-Wave, Bluetooth Smart, ISA100.5A,
WirelessHART, MiWi, etc.) and/or any of a variety of custom or
standard wired protocols (e.g., Ethernet, HomePlug, etc.), or any
other suitable communication protocol, including communication
protocols not yet developed as of the filing date of this
document.
[0161] The memory 406 includes high-speed random access memory,
such as DRAM, SRAM, DDR RAM, or other random access solid state
memory devices; and, optionally, includes non-volatile memory, such
as one or more magnetic disk storage devices, one or more optical
disk storage devices, one or more flash memory devices, or one or
more other non-volatile solid state storage devices. The memory
406, or alternatively the non-volatile memory within the memory
406, includes a non-transitory computer readable storage medium. In
some implementations, the memory 406, or the non-transitory
computer readable storage medium of the memory 406, stores the
following programs, modules, and data structures, or a subset or

information 3184) and associated images.
[0180] Each of the above identified elements may be stored in one
or more of the previously mentioned memory devices, and corresponds
to a set of instructions for performing a function described above.
The above identified modules or programs (i.e., sets of
instructions) need not be implemented as separate software
programs, procedures, or modules, and thus various subsets of these
modules may be combined or otherwise rearranged in various
implementations. In some implementations, the memory 406,
optionally, stores a subset of the modules and data structures
identified above. Furthermore, the memory 406, optionally, stores
additional modules and data structures not described above.
[0181] FIG. 5 illustrates a representative system architecture 500.
In some implementations, the server system 164 includes functional
modules for an event processor 505, an event categorizer 507, an
entity recognizer 3152, and a user-facing frontend 3150. The event
processor 505 obtains the event candidates (e.g., by processing the
video stream(s) 504 or by receiving event start information from
the video source 501, or by detecting a user press on a doorbell
button of a doorbell camera). In some implementations, the event
candidates comprise motion event candidates. In some
implementations, the event candidates include a user press on a
doorbell button of a doorbell camera. In some implementations, the
event candidates include audio, electromagnetic, olfactory, and/or
visual aspects. In some implementations, the event candidates
include motion events, approach detections, and announcement
detections. The event categorizer 507 categorizes the event
candidates into different event categories (e.g., based on data
from the event processor and/or the entity recognizer). The
user-facing frontend 3150 generates event alerts and notifications,
and facilitates review of the detected entities and events by a
reviewer through a review interface on a client device 220. The
user-facing frontend 3150 also receives user edits on the event and
entity categories, user preferences for alerts and event filters,
zone definitions for zones of interest, and the like. The event
categorizer optionally revises event categorization models and
results based on the user edits received by the user-facing
frontend. The entity recognizer optionally revises entity
classifications and/or labels based on the user edits received by
the user-facing frontend. The server system 164 also includes a
video source data database 509, person data 522, event
categorization models database 510, and event data and event masks
database 511. In some implementations, the person data 522 includes
a person's database. In some implementations, each of these
databases is part of the server database 316 (e.g., part of data
storage database 3160).
[0182] The server system 164 receives one or more video stream(s)
504 from the video source 501 (e.g., a video source 222 from FIG.
2B) and optionally receives event candidate information 502, such
as preliminary characterization information for detected entities
and events (e.g., entity and event metadata from processing
performed at the doorbell 106), and source information 503 such as
device settings for a doorbell 106 (e.g., a device profile 3165 for
doorbell 106). In some implementations, the event processor 505
communicates with the video source 501, e.g., to request additional
images such as high definition images or metadata for the video
stream(s) 504. The server system sends alerts for events 512,
alerts for detected persons 524, event timeline information 513,
and/or video data 528 (e.g., video clips corresponding to the
detected persons and/or events) to the client device 220. In some
implementations, the alerts 512 distinguish visitor approach events
from other types of motion events. In some implementations, the
alerts 512 distinguish motion events captured at a doorbell 106
from motion events captured by other smart devices (e.g., cameras
118). The server system 164 optionally receives user information
from the client device 220, such as event information 514 (e.g.,
edits to event categories), and zone definitions 515, and persons
data 526 (e.g., classification of detected persons).
[0183] A data processing pipeline processes video information
(e.g., a live video feed) received from a video source 501 (e.g.,
including a doorbell 106 and an optional controller device) and/or
audio information received from one or more smart devices in
real-time (e.g., within 10 seconds, 30 seconds, or 2 minutes) to
identify and categorize events occurring in the smart home
environment, and sends real-time event alerts (e.g., within 10
seconds, 20 seconds, or 30 seconds) and a refreshed event timeline
(e.g., within 30 seconds, 1 minute, or 3 minutes) to a client
device 220 associated with a reviewer account for the smart home
environment. The data processing pipeline also processes stored
information (such as stored video feeds from a video source 501) to
reevaluate and/or re-categorize events as necessary, such as when
new information is obtained regarding the event and/or when new
information is obtained regarding event categories (e.g., a new
activity zone is obtained from the user).
[0184] After video and/or audio data is captured at a smart device,
the data is processed to determine if any potential event
candidates or persons are present. In some implementations, the
data is initially processed at the smart device (e.g., video source
501, camera 118, or doorbell 106). Thus, in some implementations,
the smart device sends event candidate information, such as event
start information, to the server system 164. In some
implementations, the data is processed at the server system 164 for
event start detection. In some implementations, the video and/or
audio data is stored on server system 164 (e.g., in video and
source data database 509). In some implementations, the video
stream is stored on a server distinct from server system 164. In
some implementations, after a motion start is detected, the
relevant portion of the video stream is retrieved from storage
(e.g., from video and source data database 509).
[0185] In some implementations, the event identification process
includes segmenting the video stream into multiple segments then
categorizing the event candidate within each segment. In some
implementations, categorizing the event candidate includes an
aggregation of background factors, entity detection and
identification, motion vector generation for each motion entity,
entity features, and scene features to generate motion features for
the event candidate. In some implementations, the event
identification process further includes categorizing each segment,
generating or updating an event log based on categorization of a
segment, generating an alert for the event based on categorization
of a segment, categorizing the complete event, updating the event
log based on the complete event, and generating an alert for the
event based on the complete event. In some implementations, a
categorization is based on a determination that the event occurred
within a particular zone of interest. In some implementations, a
categorization is based on a determination that the event candidate
involves one or more zones of interest. In some implementations, a
categorization is based on audio data and/or audio event
characterization.
[0186] The event analysis and categorization process may be
performed by the smart device (e.g., the video source 501) and the
server system 164 cooperatively, and the division of the tasks may
vary in different implementations, for different equipment
capability configurations, and/or for different network and server
load situations. After the server system 164 categorizes the event
candidate, the result of the event detection and categorization may
be sent to a reviewer associated with the smart home
environment.
[0187] In some implementations, the server system 164 stores raw or
compressed video data (e.g., in a video and source data database
509), event categorization models (e.g., in an event categorization
model database 510), and event masks and other event metadata
(e.g., in an event data and event mask database 511) for each of
the video sources 501. In some implementations, the video data is
stored at one or more display resolutions such as 480p, 780p,
1080i, 1080p, and the like.
[0188] In some implementations, the video source 501 (e.g., the
doorbell 106) transmits a live video feed to the remote server
system 164 via one or more networks (e.g., the network(s) 162). In
some implementations, the transmission of the video data is
continuous as the video data is captured by the doorbell 106. In
some implementations, the transmission of video data is
irrespective of the content of the video data, and the video data
is uploaded from the video source 501 to the server system 164 for
storage irrespective of whether any motion event has been captured
in the video data. In some implementations, the video data may be
stored at a local storage device of the video source 501 by
default, and only video portions corresponding to motion event
candidates detected in the video stream are uploaded to the server
system 164 (e.g., in real-time).
[0189] In some implementations, the video source 501 dynamically
determines at what display resolution the video stream is to be
uploaded to the server system 164. In some implementations, the
video source 501 dynamically determines which parts of the video
stream are to be uploaded to the server system 164. For example, in
some implementations, depending on the current server load and
network conditions, the video source 501 optionally prioritizes the
uploading of video portions corresponding to newly detected motion
event candidates ahead of other portions of the video stream that
do not contain any motion event candidates; or the video source 501
uploads the video portions corresponding to newly detected motion
event candidates at higher display resolutions than the other
portions of the video stream. This upload prioritization helps to
ensure that important motion events are detected and alerted to the
reviewer in real-time, even when the network conditions and server
load are less than optimal. In some implementations, the video
source 501 implements two parallel upload connections, one for
uploading the continuous video stream captured by the doorbell 106,
and the other for uploading video portions corresponding to
detected motion event candidates. At any given time, the video
source 501 determines whether the uploading of the continuous video
stream needs to be suspended temporarily to ensure that sufficient
bandwidth is given to the uploading of the video segments
corresponding to newly detected motion event candidates.
[0190] In some implementations, the video stream uploaded for cloud
storage is at a lower quality (e.g., lower resolution, lower frame
rate, higher compression, etc.) than the video segments uploaded
for motion event processing.
[0191] As shown in FIG. 5, the video source 501 includes a doorbell
106 (which includes an image sensor), and an optional controller
device. In some implementations, the doorbell 106 includes
sufficient on-board processing power to perform all necessary local
video processing tasks (e.g., cuepoint detection for motion event
candidates, video uploading prioritization, network connection
management, etc.), and the doorbell 106 communicates with the
server system 164 directly, without any controller device acting as
an intermediary. In some implementations, the doorbell 106 captures
the video data and sends the video data to the controller device
for the necessary local video processing tasks. The controller
device optionally performs the local processing tasks for multiple
cameras. For example, there may be multiple cameras in one smart
home environment (e.g., the smart home environment 100, FIG. 1),
and a single controller device receives the video data from each
camera and processes the video data to detect motion event
candidates in the video stream from each camera. The controller
device is responsible for allocating sufficient outgoing network
bandwidth to transmitting video segments containing motion event
candidates from each camera to the server before using the
remaining bandwidth to transmit the video stream from each camera
to the server system 164. In some implementations, the continuous
video stream is sent and stored at one server facility while the
video segments containing motion event candidates are send to and
processed at a different server facility.
[0192] In some implementations, the smart device sends additional
source information 503 to the server system 164. This additional
source information 503 may include information regarding a device
state (e.g., IR mode, AE mode, DTPZ settings, etc.) and/or
information regarding the environment in which the device is
located (e.g., indoors, outdoors, night-time, daytime, etc.). In
some implementations, the source information 503 is used by the
server system 164 to perform event detection, entity recognition,
and/or to categorize event candidates. In some implementations, the
additional source information 503 includes one or more preliminary
results from video processing performed by the doorbell 106 (e.g.,
categorizations, object/entity recognitions, motion masks,
etc.).
[0193] In some implementations, the video portion after an event
start incident is detected is divided into multiple segments. In
some implementations, the segmentation continues until event end
information (sometimes also called an "end-of-event signal") is
obtained. In some implementations, the segmentation occurs within
the server system 164 (e.g., by the event processor 505). In some
implementations, the segmentation comprises generating overlapping
segments. For example, a 10-second segment is generated every
second, such that a new segment overlaps the prior segment by 9
seconds.
[0194] In some implementations, each of the multiple segments is of
the same or similar duration (e.g., each segment has a 10-12 second
duration). In some implementations, the first segment has a shorter
duration than the subsequent segments. Keeping the first segment
short allows for real time initial categorization and alerts based
on processing the first segment. The initial categorization may
then be revised based on processing of subsequent segments. In some
implementations, a new segment is generated if the motion entity
enters a new zone of interest.
[0195] In some implementations, after the event processor module
obtains the video portion corresponding to an event candidate, the
event processor 505 obtains background factors and performs motion
entity detection identification, motion vector generation for each
motion entity, and feature identification. Once the event processor
505 completes these tasks, the event categorizer 507 aggregates all
of the information and generates a categorization for the motion
event candidate. In some implementations, the event processor 505
and the event categorizer 507 are components of the video
processing module 3144. In some implementations, false positive
suppression is optionally performed to reject some motion event
candidates before the motion event candidates are submitted for
event categorization. In some implementations, determining whether
a motion event candidate is a false positive includes determining
whether the motion event candidate occurred in a particular zone.
In some implementations, determining whether a motion event
candidate is a false positive includes analyzing an importance
score for the motion event candidate. The importance score for a
motion event candidate is optionally based on zones of interest
involved with the motion event candidate, background features,
motion vectors, scene features, entity features, motion features,
motion tracks, and the like.
[0196] In some implementations, the video source 501 has sufficient
processing capabilities to perform, and does perform, entity
detection, person recognition, background estimation, motion entity
identification, the motion vector generation, and/or the feature
identification.
[0197] FIG. 6 is a block diagram illustrating a representative
client device 220 associated with a user account in accordance with
some implementations. The client device 220, typically, includes
one or more processing units (CPUs) 602, one or more network
interfaces 604, memory 606, and one or more communication buses 608
for interconnecting these components (sometimes called a chipset).
Optionally, the client device also includes a user interface 610
and one or more built-in sensors 690 (e.g., accelerometer and
gyroscope). The user interface 610 includes one or more output
devices 612 that enable presentation of media content, including
one or more speakers and/or one or more visual displays. The user
interface 610 also includes one or more input devices 614,
including user interface components that facilitate user input such
as a keyboard, a mouse, a voice-command input unit or microphone, a
touch screen display, a touch-sensitive input pad, a gesture
capturing camera, or other input buttons or controls. Furthermore,
some the client devices use a microphone and voice recognition or a
camera and gesture recognition to supplement or replace the
keyboard. In some implementations, the client device includes one
or more cameras, scanners, or photo sensor units for capturing
images (not shown). Optionally, the client device includes a
location detection device 616, such as a GPS (global positioning
satellite) or other geo-location receiver, for determining the
location of the client device.
[0198] The memory 606 includes high-speed random access memory,
such as DRAM, SRAM, DDR SRAM, or other random access solid state
memory devices; and, optionally, includes non-volatile memory, such
as one or more magnetic disk storage devices, one or more optical
disk storage devices, one or more flash memory devices, or one or
more other non-volatile solid state storage devices. The memory
606, optionally, includes one or more storage devices remotely
located from one or more processing units 602. The memory 606, or
alternatively the non-volatile memory within the memory 606,
includes a non-transitory computer readable storage medium. In some
implementations, the memory 606, or the non-transitory computer
readable storage medium of the memory 606, stores the following
programs, modules, and data structures, or a subset or superset
thereof: [0199] an operating system 618 including procedures for
handling various basic system services and for performing hardware
dependent tasks; [0200] a network communication module 620 for
connecting the client device 220 to other systems and devices
(e.g., client devices, electronic devices, and systems connected to
one or more networks 162) via one or more network interfaces 604
(wired or wireless); [0201] an input processing module 622 for
detecting one or more user inputs or interactions from one of the
one or more input devices 614 and interpreting the detected input
or interaction; [0202] one or more applications 624 for execution
by the client device (e.g., games, social network applications,
smart home applications, and/or other web or non-web based
applications) for controlling devices (e.g., sending commands,
configuring settings, etc. to hub devices and/or other client or
electronic devices) and for reviewing data captured by the devices
(e.g., device status and settings, captured data, or other
information regarding the hub device or other connected devices);
[0203] a user interface module 626 for providing and displaying a
user interface in which settings, captured data, and/or other data
for one or more devices (e.g., smart devices 204 in smart home
environment 100) can be configured and/or viewed; [0204] a
client-side module 628, which provides client-side functionalities
for device control, data processing and data review, including but
not limited to: [0205] a hub device and device control module 6280
for generating control commands for modifying an operating mode of
the hub device or the electronic devices in accordance with user
inputs; [0206] a video analysis module 6281 for analyzing captured
video data, e.g., to detect and/or recognize persons, objects,

providing user interfaces for reviewing data processed by the
server system 164, including but not limited to: [0208] an event
review submodule 6283 for reviewing events (e.g., motion and/or
audio events), and optionally enabling user edits and/or updates to
the events; and [0209] a person's review submodule 6284 for
reviewing data and/or images regarding detected persons and other
entities, and optionally enabling user edits and/or updates to the
persons data; [0210] a quick action (QA) presentation module 6285
for providing a subset of quick actions identified by the server
system 164; and [0211] a remote interaction module 6286 for
interacting with a remote person (e.g., a visitor to the smart home
environment 100), e.g., via a doorbell 106 and/or the server system
164; and [0212] client data 630 storing data associated with the
user account and electronic devices, including, but not limited to:
[0213] account data 6300 storing information related to both user
accounts loaded on the client device and electronic devices (e.g.,
of the video sources 501) associated with the user accounts,
wherein such information includes cached login credentials, hub
device identifiers (e.g., MAC addresses and UUIDs), electronic
device identifiers (e.g., MAC addresses and UUIDs), user interface
settings, display preferences, authentication tokens and tags,
password keys, etc.; and [0214] a local data storage database 6302
for selectively storing raw or processed data associated with
electronic devices (e.g., of the video sources 501, such as a
doorbell 106), optionally including entity data such as the entity
data 4344 described previously.
[0215] Each of the above identified elements may be stored in one
or more of the previously mentioned memory devices, and corresponds
to a set of instructions for performing a function described above.
The above identified modules or programs (i.e., sets of
instructions) need not be implemented as separate software
programs, procedures, modules or data structures, and thus various
subsets of these modules may be combined or otherwise rearranged in
various implementations. In some implementations, the memory 606,
optionally, stores a subset of the modules and data structures
identified above. Furthermore, the memory 606, optionally, stores
additional modules and data structures not described above.
[0216] FIGS. 7A-7C illustrate a representative person detection and
recognition process in accordance with some implementations. FIG.
7A shows an image 700 corresponding to a field of view of a first
camera associated with a doorbell 106 of an electronic greeting
system. In some implementations, the electronic greeting system
comprises one or more devices of the smart home environment 100
and/or the server system 164. As shown in FIG. 7A, no potential
visitors are present in image 700. FIG. 7B shows an image 710
corresponding to a field of view of a second camera associated with
doorbell 106. In some implementations, upon initial detection of a
person 712 (discussed in more detail below), doorbell 106
automatically switches to the second camera as it has a field of
view more conducive to visitor detection. In some implementations,
however, doorbell 106 includes only one camera, and image 700
remains after the initial detection of a person. In some
implementations, upon detection of a motion event (i.e., person 712
enters the field of view of the camera), the system (e.g., the
electronic greeting system, including but not limited to a
processor of doorbell 106) analyzes the motion event to determine
whether the person 712 is a visitor (e.g., whether the person 712
is approaching the doorbell 106). For example, as the person 712
moves in the field of view, the system measures the height (or
another dimension) of the person's face (or other body
characteristics, such as the person's torso, shoulder width, and
the like). The face height 714 in FIG. 7B increases to a larger
face height 716 in FIG. 7C. In this example, based on whether the
face height increase satisfies one or more face height increase
criterion, the system determines that the person 712 is approaching
the entryway, and thereby classifies the person 712 as a visitor.
In some implementations, analyzing the motion event additionally or
alternatively includes analyzing data from a motion sensor to
determine whether the motion data satisfies motion criteria, and/or
analyzing data from a proximity sensor (e.g., a PIR sensor) to
determine whether the proximity data satisfies proximity criteria.
For example, a PIR sensor detects a heat signature, and a processor
associated with the electronic greeting system analyzes the heat
signature to determine whether the heat signature exceeds a
predetermined threshold. In accordance with a detection that the
heat signature exceeds the threshold, a person 712 associated with
the heat signature is classified as a visitor. As another example,
an audio sensor detects an audio signal, and a processor associated
with the electronic greeting system analyzes the audio signal to
detect an audio event indicative of an approaching person, such as
footsteps. In accordance with a detection that an amplitude or
decibel level of the audio event (e.g., the volume of the detected
footsteps) passes a predetermined threshold, a person 712
associated with the audio event is classified as a visitor. In some
implementations, a processor associated with the electronic
greeting system determines a direction of movement and/or a
distance of a detected person based on a signal from a direction
and/or distance sensor, such as a radar sensor. In some
implementations, a processor associated with the electronic
greeting system uses a combination of any of the aforementioned
examples to detect an approaching person and classify the person as
a visitor.
[0217] FIGS. 8A-B illustrate representative visitor status
classification operations in accordance with some implementations.
FIG. 8A shows a visitor 820 in an image 810 (e.g., corresponding to
a doorbell 106's field of view at a first time), and FIG. 8B shows
a visitor 830 in an image 822 (e.g., corresponding to a doorbell
106's field of view at a second time). In some implementations, the
electronic greeting system determines whether the visitors are
known to the system (e.g., based on a facial recognition
operation). In some implementations, the electronic greeting system
(e.g., a processor of doorbell 106) performs a face cropping
operation and performs the facial recognition operation on the
cropped faces 822 and 832. For example, a processor associated with
the electronic greeting system crops an image 822 of person 820's
face out of image 810 and sends the cropped image 822 to a server
for facial recognition processing. In some implementations, if
multiple faces are detected, a processor associated with the
electronic greeting system separately crops each face and sends
each face to a server for facial recognition processing.
Alternatively, the processor crops an area out of image 810 that
includes each detected face and sends the cropped area to the
server for facial recognition processing. Alternatively, the
processor sends the entire frame 810 to the server for facial
recognition processing. In some implementations, the camera itself
performs the facial recognition processing. In some
implementations, the electronic greeting system sends the images
810, 822 and/or the images 822, 832 to a user of the smart home
environment 100 (e.g., as part of a notification or alert). In some
implementations, the electronic greeting system analyzes the images
810, 822 to determine context information for the visitors 820,
830.
[0218] FIGS. 9A-D are flow diagrams illustrating methods of
detecting and and/or responding to a visitor to a smart home
environment in accordance with some implementations. In some
implementations, the methods are performed by: (1) one or more
smart devices 204 (e.g., a doorbell 106); (2) the server system
164; (3) a client device 220; or (4) a combination thereof. In some
instances and implementations, the various operations of the
methods described herein are interchangeable, and respective
operations of the methods are performed by any of the
aforementioned devices, systems, or combination of devices and/or
systems. For example, the obtaining of a motion stream (904) is
optionally performed by doorbell(s) 106 or server system 164. In
some implementations, video and/or data streams are sent from a
doorbell 106 to a client device 220 over a network (e.g., WLAN)
that does not include server system 164. In some implementations,
the methods are governed by instructions that are stored in one or
more non-transitory computer-readable storage mediums, and that are
executed by one or more processors, such as the CPU(s) 302 of
server system 164 and/or the CPU(s) 402 of smart device 204 (e.g.,
a doorbell 106). For convenience, the method operations will be
described below as being performed by particular component or
device, but should not be construed as limiting the performance of
the operation to the particular device in all implementations.
[0219] FIG. 9A illustrates a method 900 of detecting and responding
to a visitor to a smart home environment in accordance with some
implementations. The doorbell 106 obtains a video stream (902) from
a camera associated with or included in the doorbell 106. The
server system 164 derives a motion stream (904) from the video
stream of the camera. In some implementations, the motion stream
comprises data or metadata derived from the video stream of the
camera which is analyzed to detect information regarding an amount
of motion in a field of view of the camera. In some
implementations, the motion stream and the video stream are both
streamed from the camera to the server system 164 for analysis.
Alternatively, only the video stream is streamed to the server
system 164 for deriving a motion stream and analyzing the motion
stream. In some implementations, the video stream and/or the motion
stream are streamed to the server system 164 only when an amount of
motion satisfying a threshold is detected. In some implementations,
the motion stream comprises the video stream with metadata
comprising motion data. In some implementations, the motion stream
is a separate data stream (e.g., not including video data from the
video stream) comprising motion data corresponding to the video
stream. In some implementations, deriving the motion stream from a
video stream of the camera includes comparing an amount of detected
motion in a field of view of the camera to a threshold. For
example, if an amount of detected motion is greater than a
predetermined threshold, data associated with the detected motion
is included in the motion stream for further analysis; otherwise,
data associated with the detected motion is not included in the
motion stream. Setting a predetermined motion threshold enables the
system to disregard some trivial movements such as leaves blowing
in the breeze.
[0220] The server system 164 analyzes (906) the motion stream to
determine if a visitor is approaching the entryway. In some
implementations, server system 164 analyzes the motion stream by
tracking a dimension of a characteristic of the visitor (e.g., the
visitor's path, the visitor's proximity to the entryway, a
dimension of the visitor's face, a dimension of the visitor's body,
and/or any other physical characteristic of the visitor, such as a
height or shape of any part of the body, including the body as a
whole) over time. For example, if a height or width of the visitor
grows over time, or if a dimension of the visitor's face increases
over time, the visitor is determined to be approaching the
entryway. Additionally or alternatively, if the dimension of the
characteristic of the visitor exceeds a threshold, the visitor is
determined to be approaching the entryway. For example, if a
detected person enters from outside of the field of view of the
camera, but is determined to be in close proximity (e.g., within 3
ft, 5 ft, or loft) to the entryway the detected person is deemed to
be a visitor. In some implementations, a detected person is deemed
to be a visitor in accordance with a determination that the
detected person is closer to the entryway than to a public space
(e.g., a public sidewalk).
[0221] In some implementations, in addition to or as an alternative
to analyzing a motion stream, the server system 164 determines if a
visitor is approaching the entryway by detecting a presence of a
person (sometimes referred to herein as "presence information").
Several example implementations for detecting presence information
are described below.
[0222] For example, determining that a visitor is approaching the
entryway includes obtaining and analyzing presence information
indicative of an approaching visitor or a visitor in proximity to
the entryway. In some implementations, part or all of the presence
information is derived from motion data of one or more motion
sensors of the smart home environment, including, for example, a
passive infrared (PIR) sensor, an ultrasonic sensor, a microwave
sensor, and/or a tomographic sensor. In some implementations, part
or all of the presence information is derived from video data of
one or more cameras having a field of view corresponding to the
entryway. For example, presence information is derived by
determining that an amount of motion detected by a camera or other
type of motion sensor meets one or more motion criteria, such as an
amount of motion exceeding a threshold. As a further example,
presence information is derived by analyzing a plurality of image
frames to determine whether a difference in position of an object
(e.g., measured in pixels) in the plurality of image frames exceeds
a threshold. In some implementations, part or all of the presence
information is derived from an audio signal obtained from an audio
sensor. For example, an audio signal capturing an audio event (such
as a footstep, a verbal announcement, a doorbell sound, or a door
knock) is indicative of a visitor's presence.
[0223] As another example, determining that a visitor is
approaching the entryway includes comparing a dimension of a
characteristic of the visitor over time. In some implementations,
determining that the visitor is approaching includes tracking one
or more dimensions of the visitor over time. For example,
determining that a visitor is approaching the entryway includes
obtaining a first measurement of a dimension of a characteristic of
the visitor (such as an initial height measurement of the visitor's
head), obtaining a subsequent measurement of the dimension of the
characteristic of the visitor (such as a second height measurement
of the visitor's head at a predetermined amount of time after the
initial height measurement), and determining whether a difference
between the first measurement and the subsequent measurement
exceeds a threshold. For example, if the visitor's head height
increases between the first and second measurements, the visitor is
likely approaching; otherwise, if the visitor's head height does
not increase, the visitor is likely not approaching or is standing
still.
[0224] As another example, determining that a visitor is
approaching the entryway comprises determining that the visitor is
within a threshold distance to the entryway. For example, if a
person is detected within a predetermined distance from the
entryway, the person is determined to be an approaching visitor.
For example, once the visitor is within 15 feet, 10 feet, or 5 feet
of the entryway, the observation window is initiated, and context
information is obtained. In some implementations, initiating the
observation window in response to the determination that the
visitor is approaching the entryway includes initiating the
observation window in response to the determination that the
visitor is on a track to the entryway (e.g., has entered a walkway,
hallway, or perimeter gate leading to the entryway).
[0225] As another example, determining that a visitor is
approaching the entryway includes deriving a motion stream. In some
implementations, the motion stream is derived from a video stream
of the camera. In some implementations, the motion stream is
derived from the video stream by detecting information regarding an
amount of motion in a field of view of the camera, or by comparing
an amount of detected motion in a field of view of the camera to a
threshold. In some implementations, the motion stream includes a
motion mask for a motion event detected in the video stream.
[0226] Upon a determination that a visitor is approaching the
entryway, the server system 164 initiates an observation window
(908). In some implementations, a length of the observation window
is predefined to correspond to a reasonable amount of time for the
visitor to complete the approach to the entryway, or to reach a
threshold distance to the entryway. For example, a visitor
approaching an entryway located at the end of a long walkway is
given more time to reach the entryway (or a threshold distance from
the entryway) than a visitor approaching an entryway located at the
end of a shorter walkway. In some implementations, the method
additionally or alternatively includes initiating the observation
window in response to a determination that the visitor is within a
threshold distance to the entryway, where the threshold is
predetermined based on a layout of the entryway. In some
implementations, the electronic greeting system analyzes the layout
of the entryway and automatically sets a threshold based on an
amount of time it takes for an initially detected person to reach a
component of the entryway, such as a door or a gate. Additionally
or alternatively, a user manually sets the predetermined threshold
using an interface of the electronic greeting system. In some
implementations, the observation window is initiated when the
visitor is close enough to the entryway to enable an interaction
with the electronic greeting system (e.g., a doorbell press or
verbal communication). In some implementations, the visitor is
determined to have reached the threshold distance to the entryway
based on data from a range sensor, such as a passive infrared
("PIR") sensor or radar.
[0227] Upon initiating the observation window, the doorbell 106
obtains context information (910). In some implementations, the
doorbell 106 is constantly obtaining context information, while in
other implementations, the doorbell begins obtaining context
information upon initiation of the observation window. In some
implementations, context information is based on a detected
announcement event (e.g., a doorbell press, a door knock, a keypad
entry, or a verbal announcement); a facial recognition analysis;
one or more behavior characteristics of the visitor; one or more
clothing characteristics of the visitor; a time during which the
visitor approaches the entryway (e.g., a time of day or day of the
week); a verbal announcement of the visitor; proximity in time to a
prescheduled event; proximity in time to a prescheduled status of
the smart home environment; a status or location of the user;
and/or a timing of the detected visitor action compared to a timing
of the identification of the motion event involving the visitor
approaching the entryway. More details regarding the obtaining of
context information are provided below.
[0228] Upon initiating the observation window, the server system
164 performs a facial recognition operation (912) based on one or
more frames of the motion stream sent to the server by doorbell
106, and determines, based on an outcome of the facial recognition
operation, whether the visitor is known to the electronic greeting
system (e.g., illustrated in FIG. 8A) or unknown to the electronic
greeting system (e.g., illustrated in FIG. 8B).
[0229] The server system 164 characterizes the visitor (914)
according to a result of the facial recognition (912) and the
context information (910). For example, the visitor is
characterized as one or more of known, unknown, expected,
unexpected, suspicious, and the like. In some implementations, the
characterizations are weighted in accordance with the context
information and the facial recognition. In some implementations,
the server system further characterizes the visitor based on
whether the visitor announced the visit (e.g., rang the doorbell or
knocked on the door) within a closing of the observation window. In
some implementations, the observation window closes at the earlier
of: (1) a visitor announcement (e.g., a doorbell press or knocking
event); and (2) a predetermined time threshold (e.g., the visitor
has lingered for more than the predetermined time threshold without
making an announcement). In some implementations, the predetermined
time threshold is dynamic, and depends on the context information
(e.g., longer observation windows when the context information
suggests a higher level of safety or concern, and shorter
observation windows when the context information suggests a lower
level of safety or concern). In some implementations, the context
information includes a determination of whether the visitor made an
announcement (e.g., rang the doorbell or knocked on the door)
before the observation window expired.
[0230] The server system initiates a response (916) in accordance
with the visitor characterization (914). In some implementations,
the server system initiates a response (916) in accordance with
only the context information (910), or only the facial recognition
result (912). In some implementations, the server system initiates
a response (916) in accordance with the context information (910)
and the facial recognition result (912), but without any further
characterization (914). Examples of responses are illustrated in
FIGS. 10-14 and discussed below.
[0231] The doorbell 106 outputs the response (918) to the visitor
(e.g., broadcasts a voice message, prompts the visitor to reply,
and the like). In some implementations, another smart device 204
implements the response (e.g., smart door lock 120 unlocks the door
to let the visitor in). The doorbell 106 obtains a reply (922) and
sends the reply to the server 164 (e.g., a verbal or text message
left by the visitor). The server 164 receives the reply (924), and
initiates a subsequent response (916) (e.g., stores the reply for
later retrieval by the user, or initiates a notification). In some
implementations, the server responds (916) to the characterization
of the visitor (914) and/or the reply (924) by sending a
notification (920) to the client device 220. Upon receipt of the
notification, a user may instruct the server 164 to initiate a
subsequent response (916).
[0232] FIG. 9B illustrates a method 930 of detecting and responding
to a visitor to a smart home environment by presenting a user with
appropriate responses in accordance with some implementations.
[0233] The doorbell 106 obtains a video stream (932) from a camera
associated with or included in the doorbell 106. The server system
164 derives a motion stream (934) from the video stream of the
camera (e.g., as discussed previously with respect to operation
904). In some implementations, deriving the motion stream from a
video stream of the camera includes detecting information regarding
an amount of motion in a field of view of the camera. In some
implementations, deriving the motion stream from a video stream of
the camera includes comparing an amount of detected motion in a
field of view of the camera to a threshold. For example, if an
amount of detected motion is greater than a predetermined
threshold, data associated with the detected motion is included in
the motion stream for further analysis; otherwise, data associated
with the detected motion is not included in the motion stream.
[0234] The server system 164 analyzes (936) the motion stream to
determine if a visitor is approaching the entryway (e.g., as
discussed previously with respect to operation 906). In some
implementations, server system 164 analyzes the motion stream by
comparing a dimension of a characteristic of the visitor (e.g., the
visitor's path, the visitor's proximity to the entryway, a
dimension of the visitor's face, a dimension of the visitor's body,
and/or any other physical characteristic of the visitor, such as a
height or shape of any part of the body, including the body as a
whole) over time. For example, if a height or width of the visitor
grows over time, or if a dimension of the visitor's face increases
over time, the visitor is determined to be approaching the
entryway. Additionally or alternatively, if the dimension of the
characteristic of the visitor exceeds a threshold, the visitor is
determined to be approaching the entryway.
[0235] Upon detecting an approaching visitor, the doorbell 106
obtains (938) context information (e.g., as discussed previously
with respect to operation 910). In some implementations, the
doorbell 106 is constantly obtaining context information, while in
other implementations, the doorbell begins obtaining context
information upon detection of an approaching visitor. In some
implementations, context information is based on a detected
announcement event (e.g., a doorbell press, a door knock, a keypad
entry, or a verbal announcement); a facial recognition analysis;
one or more behavior characteristics of the visitor; one or more
clothing characteristics of the visitor; a time of day during which
the visitor approaches the entryway; a verbal announcement of the
visitor; proximity in time to a prescheduled event; proximity in
time to a prescheduled status of the smart home environment; a
status or location of the user; and/or a timing of the detected
visitor action compared to a timing of the identification of the
motion event involving the visitor approaching the entryway. More
details regarding the obtaining of context information are provided
below.
[0236] Based on the context information, the server system
identifies a plurality of appropriate actions (940) available to a
user of the client device for interacting with the visitor via the
electronic greeting system. An action is defined as "appropriate"
if it is determined to be an action likely to be selected by the
user based on the context information. An appropriate action is
therefore relevant, applicable, useful, pertinent, and/or suitable
for responding to the visitor depending on the context information.
In some implementations, a collection of actions is stored in a
database (e.g., database 316, FIG. 3A), and ranked in terms of the
applicability, relevance, and/or usefulness of each action to a
present situation involving a specific visitor and specific context
information. In some implementations, the ranked actions are then
ordered based on the ranking. In these implementations, an action
is defined as "appropriate" if it at or near the top of the ranking
(e.g., one of the top 3, 5, or 10 actions in the ranking). In some
implementations, the higher an action is ranked, the more
appropriate the action is considered to be. In some
implementations, an action is defined as "appropriate" if its rank
is above a predetermined threshold (e.g., the ten highest ranked
actions), with a subset of appropriate actions (e.g., three
actions) being presented to the user. In other implementations, the
threshold is determined based on a number of actions that can be
presented to the user in a single user interface of the client
device (e.g., if the user interface can only display three actions
at once, then the three highest ranked actions are determined to be
"appropriate"), and all of the appropriate actions are
simultaneously presented to the user in the same user interface. In
some implementations, a number of actions to be presented to the
user is based on an amount of display space available in a quick
action area of a user interface of the client device. Examples of
appropriate actions are provided below.
[0237] Upon identifying a plurality of appropriate actions
available to the user of a client device for interacting with the
visitor via the electronic greeting system, the server system 164
presents a notification (942) of the identified appropriate actions
to the user at the client device 220. Examples of notifications are
illustrated in FIG. 10.
[0238] The server system 164 receives a selection (944) of an
identified action from the user of the client device 220, and
implements the action by outputting a response (946) at the
doorbell 106. The doorbell 106 records a reply (948) and sends the
reply to the server 164 (e.g., a message left by the visitor). The
server 164 receives the reply (950), identifies updated actions
(940), and presents the updated actions to the user (942) at the
client device 220. In some implementations, the server system 164
identifies one or more appropriate devices for the identified
action and sends the identified action to the appropriate
device(s). For example, the server system 165 determines that the
appropriate device for an unlock action is a smart door lock and
sends the unlock action to the smart door lock. As another example,
the server system 165 determines that the appropriate devices for
an alert action include a floodlight device in the smart home
environment, a remote security device (e.g., a computer at a local
police station), and the doorbell 106 (e.g., to issue a warning to
the visitor) and sends the alert action to those devices.
[0239] FIG. 9C is an operational flow diagram 960 illustrating a
representative method for interacting with a visitor in accordance
with some implementations. Upon detecting a visitor announcement
(962) (e.g., a doorbell press or a knock), in accordance with a
determination that a user of the client 220 device is currently
operating an application of the electronic greeting system on the
client device 220, the interface advances to a call screen (964)
(e.g., FIGS. 10C, 13A). However, in accordance with a determination
that a user of the client device 220 is not currently operating an
application of the electronic greeting system on the client device
220, an alert (970) is presented to the user (e.g., FIGS. 11A,
11B). After finishing an interaction with the alert, the interface
advances to an events list (966), showing a list of past visitor
events (e.g., FIG. 10F). After finishing an interaction on the call
screen (e.g., by pressing a "Dismiss" affordance), the interface
advances to the events list (966), or if the user was interacting
with a different screen of the electronic greeting system
application, the interface advances to the previous screen
(968).
[0240] FIG. 9D is an operational flow diagram 980 illustrating a
representative method for interacting with a visitor in accordance
with some implementations. Upon detecting a visitor announcement
(982) (e.g., a doorbell press or a knock) or a lingering visitor,
the interface provides a talkback option (984) (e.g., FIG. 13A
"Talkback" affordance, and an assistant option (986) (e.g., FIG.
13A "Assistant" affordance). Upon selection of the talkback option
(984), the interface provides a talkback screen for sending a voice
communication (e.g., FIG. 13B) and/or a text-to-speech
communication (e.g., FIG. 13C). In some implementations, the
greeting system provides smart suggestions for responding to a
message during a text-to-speech communication. Upon selection of
the assistant option (986), the interface advances to provide an
assistant screen (e.g., FIG. 13D). While in the assistant screen,
the user can optionally respond by selecting the "Talkback"
affordance, which then causes the interface to advance to a
talkback screen (e.g., 13B or 13C). In some implementations, at the
end of an assistant session (e.g., an end of an interaction between
the visitor and the virtual assistant), the user is provided with a
summary (988) of the interaction (e.g., FIG. 14). In some
implementations, the talkback interface is equivalent to the talk
interface (selected through the call screen). If the user does not
answer after a predefined threshold amount of time, or has set the
client device to a do-not-disturb mode, the virtual assistant
responds to the visitor based on certain context information
(explained in more detail below) or based on customized user
preferences. In some implementations, while the virtual assistant
is interacting with the visitor, the user has an option to take
over the interaction via a voice call or a text-to-speech call in a
talkback interaction (984), as discussed above. In some
implementations, after the interaction ends, user is provided with
a summary (988) of the interaction (e.g., FIG. 14).
[0241] FIGS. 10A-F illustrate representative user interfaces for
notifying a user of a client device that a visitor is approaching,
and for facilitating an interaction with the visitor. In some
implementations, the user interface is presented at a client device
220 (e.g., utilizing user interface module 626 and/or persons
review module 6284). FIG. 10A illustrates a home screen 1002 for
the electronic greeting system application, including an image of
the camera's field of view 1004 (e.g., a first camera pointed
towards the entryway). In some implementations, the image of the
scene is part of a video clip (e.g., in gif format) showing
activity of the detected visitor. In some implementations, the
video clip is composed of a plurality of frames from the camera
(e.g., every 10th, 30th, or 100th frame) corresponding to an event
involving the detected person.
[0242] Upon detecting a visitor approaching the entryway, a visitor
announcement (e.g., pressing a doorbell or knocking on the door),
or a visitor lingering at the entryway for a threshold amount of
time without making any announcement, or any other motion event
involving a visitor, the interface advances to call screen 1006
(FIG. 10C). In some implementations, call screen 1006 slides in
from an edge of the screen (e.g., the bottom, as in FIG. 10B). In
some implementations, call screen 1006 includes a more detailed
image provided from a different camera (e.g., a camera embedded the
doorbell 106) that is better situated for capturing images or video
of a front profile of the visitor. In some implementations, the
image of the scene is part of a video clip (e.g., in gif format)
showing activity of the detected visitor. In some implementations,
the video clip is composed of a plurality of frames from the camera
(e.g., every 10th, 30th, or 100th frame) corresponding to an event
involving the detected person. In some implementations, the camera
views are automatically switched in accordance with a detection of
a motion event (e.g., the motion event camera feed switches to the
visitor detail camera feed upon detection of an approaching
visitor).
[0243] In some implementations, call screen 1006 includes a label
for the specific entryway at which the visitor is present (e.g.,
"Front Door"), a notification regarding relevant information about
the visitor (e.g., "Doorbell rang 15s ago," or "Lingering for the
last 30s"), an "Dismiss" affordance 1008 (sometimes labeled as
"Ignore"), a "Talk" affordance 1010, and an "Actions" affordance
1012.
[0244] Upon selection of Talk 1010, the interface advances to talk
screen 1014 (FIG. 10D). In some implementations, Dismiss 1008 and
Action 1012 disappear (or are otherwise indicated as unselectable)
while Talk 1010 is replaced with a "Done" affordance 1016,
indicating that the user interface is in a talk mode (e.g., the
client device records a verbal message from the user and sends it
to the visitor). In some implementations, upon selection of Done
1016, the interface exits talk mode (e.g., the call ends, or the
voice recording stops) and returns to the call screen 1006 (FIG.
10E), advances to an events list screen 1018, or exits the smart
home application. In some implementations, upon selection of
Dismiss 1008, the user exits the call screen 1006, and the
interface advances to the events list screen 1018 (FIG. 10F), or
exits the smart home application. In accordance with some
implementations, the events list screen 1018 includes a list of
events 1020, including reports of past interactions.
[0245] FIGS. 10G-L illustrate representative user interfaces for
facilitating an interaction between the user and the visitor by
providing quick actions to the user. In the call screen 1006, in
response to selection of Actions 1012 (FIG. 10G), a list of
appropriate quick actions 1024 appears in a quick actions selection
screen 1022 (FIG. 10H). In accordance with some implementations,
selecting the quick action ("We'll be right there.") removes the
quick actions 1024 display and the interface returns to call screen
1006 while the communication ("We'll be right there.") 1026 is
delivered to the visitor (FIG. 10I), e.g., via a speaker at a
doorbell device 106.
[0246] In some implementations, the displayed quick actions 1024
include communication-based actions only, action-based actions
only, or at least one communication-based action and at least one
action-based action. FIG. 10J is an example quick actions selection
screen 1022a for an unknown or unexpected visitor 1030. In
accordance with some implementations, the actions 1032, 1034, and
1036 correspond with contextual information regarding the visitor
1030 (e.g., are deemed appropriate based on the contextual
information) and are all communication-based. FIG. 10K is an
example quick actions selection screen 1022b for a known and/or
expected visitor 1034. The communication-based actions 1042 and
1044, as well as the action-based action 1046 correspond with
contextual information regarding the visitor 1040. FIG. 10L is an
example quick actions selection screen 1022c for an unknown and
potentially unsafe visitor 1050. The communication-based action
1052, as well as action-based actions 1054 and 1056, correspond
with contextual information regarding the visitor 1050. Upon
selection of a quick action, the electronic greeting system carries
out the task corresponding to the selected quick action. In some
implementations, upon selection of the quick action, the user
device interface returns to the call screen 1006 (FIG. 10I).
[0247] FIGS. 11A and 11B illustrate representative user interfaces
for displaying a notification with quick actions in accordance with
some implementations. In FIG. 11A, user interface 1102 includes a
notification 1104 which includes a first section 1106 including an
image of the visitor or an image of the entryway, and relevant
information about the entryway (e.g., "Front Door") and the motion
event (e.g., "Someone's at the door."). The interface further
includes a second section 1108 including a list of appropriate
quick actions. In some implementations, the quick actions are
automatically displayed in the initial notification. In other
implementations, the initial notification includes an Actions
affordance (e.g., as shown in FIG. 10G), the selection of which
opens the list of quick actions. In some implementations, the first
and second sections 1106 and 1108 form a single notification
section. In FIG. 11B, the user interface 1110 includes affordances
1112 (similar to those in FIG. 10C), and a list of quick actions
1114. For client devices with relatively large screens (e.g., FIG.
11B), the quick actions optionally take up a smaller portion of the
screen. In some implementations, the image takes up the entire
background of the interface, with the quick actions being displayed
in a foreground layer.
[0248] FIGS. 12A-D illustrate representative user interfaces for
displaying notifications in accordance with some implementations.
FIG. 12A depicts an interface 1202 for when a family member answers
the call while the user is in the call screen 1006 (FIG. 10C). In
this case, the talk and actions affordances disappear, are faded,
or are otherwise identified as being unselectable in accordance
with some implementations. In some implementations, the interface
shows information relevant to the call (e.g., through subtitles)
between the visitor and the family member. In some implementations,
one or both of the talk and actions affordances remain selectable,
allowing for multiple people to join the call at the same time
and/or quick actions to be taken while another person is on the
call. FIG. 12B depicts an interface 1204 for when two people answer
a call simultaneously. In some implementations, an error message is
displayed notifying the user that the call could not be completed.
However, in some implementations, when two people answer a call
simultaneously, both people are connected to the call. FIG. 12C
depicts an interface 1206 for when there is not enough bandwidth to
support both audio and video data. In some implementations, the
video may be dropped in favor of supporting a lower bandwidth
audio- and/or text-based interaction. In some implementations, a
message is displayed in the user interface notifying the user of
the bandwidth limitations. FIG. 12D depicts an interface 1208 for
when the camera associated with the entryway (e.g., a camera of a
doorbell 106) is off. In some implementations, the image cannot be
displayed, and a message is displayed in the user interface
notifying the user. In some implementations, a switch (or any other
control-based affordance) is displayed in the user interface
allowing the user to turn the camera on.
[0249] FIGS. 13A-D illustrate representative user interfaces for
interacting with a visitor by way of a conversation in accordance
with some implementations. FIG. 13A includes an interface screen
1302 that includes a Talkback affordance for initiating a talkback
conversation, an Assistant affordance for initiating an
Assistant-led conversation, and an Ignore affordance for ignoring
the call. In some implementations, the interface includes a crop of
the visitor's face. FIG. 13B includes an interface screen 1304,
which depicts an Assistant call including a live transcription of
an interaction between the Assistant (e.g., "How can I help you?")
and the visitor (e.g., "I'm here to drop off the package"). In some
implementations, the visitor's message is an audio message, and the
interface includes a play button by the message which controls
playback of the audio recording. FIG. 13C illustrates an interface
1306 for responding to a message in a text-to-speech conversation
with suggested replies (e.g., "Leave it on the porch" and "Okay").
FIG. 13D includes a live transcription of the interaction that
started in FIG. 13C, with the user having selected the "Leave it on
the porch" suggestion.
[0250] FIG. 14 illustrates representative summary notifications
including interaction summaries (e.g., FIG. 9D, summary 988) in
accordance with some implementations. In some implementations,
summaries 1402-1408 include information identifying the visitor
(e.g., "UPS," "Michael," and "Stranger"), as well as content
information (e.g., a portion of the visitor's announcement message)
and/or activity information (e.g., "left a message," "package
delivered", and "assistant let him in"). In some implementations,
summary 1410 additionally includes a video clip of the visitor.
[0251] In light of the principles described above with reference to
the figures, we now turn to certain implementations.
[0252] Some implementations include a method of identifying and
responding to a visitor to a smart home environment. In some
implementations, the method includes: (1) obtaining a motion stream
from a camera of the smart home environment, the camera having a
field of view of an entryway of the smart home environment; (2)
determining based on an analysis of the motion stream that a
visitor is approaching the entryway; (3) performing a facial
recognition operation based on one or more frames of the motion
stream and determining based on an outcome of the facial
recognition operation whether the person is known to the smart home
environment; (4) initiating an observation window in response to
the determination that a visitor is approaching; (5) during the
observation window, obtaining and associating context information
from one or more sensors of the smart home environment; and (6) at
the end of the observation window, initiating a response to the
visitor approaching the entry way based on the context information
and the outcome of the facial recognition operation.
[0253] In some implementations, a "visitor" includes any of a
resident of the smart home environment, a non-resident of the smart
home environment, a known person (e.g., a person recognized by the
electronic greeting system), and an unknown person (e.g., a person
not recognized by the electronic greeting system) in a vicinity of
an entryway of the smart home environment.
[0254] In some implementations, obtaining the motion stream from a
camera includes detecting information regarding an amount of motion
in a field of view of the camera. In some implementations, deriving
the motion stream from a video stream of the camera includes
comparing an amount of detected motion in a field of view of the
camera to a threshold. For example, if an amount of detected motion
is greater than a predetermined threshold, data associated with the
detected motion is included in the motion stream for further
analysis; otherwise, data associated with the detected motion is
not included in the motion stream.
[0255] In some implementations, determining if a visitor is
approaching the entryway includes comparing a dimension of a
characteristic of the visitor (e.g., the visitor's path, the
visitor's proximity to the entryway, a dimension of the visitor's
face, a dimension of the visitor's body, and/or any other physical
characteristic of the visitor, such as a height or shape of any
part of the body, including the body as a whole) over time. For
example, if a height or width of the visitor grows over time, or if
a dimension of the visitor's face increases over time, the visitor
is determined to be approaching the entryway. Additionally or
alternatively, if the dimension of the characteristic of the
visitor exceeds a threshold, the visitor is determined to be
approaching the entryway.
[0256] In some implementations, the method further includes
capturing from the motion stream a crop of a face of the visitor
when a dimension of the face exceeds a threshold proportion of a
frame of the motion stream, or when a dimension of the face exceeds
a threshold.
[0257] In some implementations, determining that a visitor is
approaching the entryway includes detecting the visitor entering an
activity area in proximity to the entryway. In some
implementations, dimensions and location of an activity area depend
on the geography of the entryway and proximity of the entryway to
public spaces. In some implementations, a location of an activity
area depends on the location of a delivered package. For example,
when a package is delivered in a vicinity to the entryway, the
electronic greeting system instantiates an activity area around the
package, including a predetermined buffer area surrounding the
package. When a visitor is determined to have entered the
predetermined buffer area, the electronic greeting system
determines that the visitor is approaching the entryway. In some
implementations, the determination that the visitor has entered the
activity area is made in addition or in the alternative to any
determination that the visitor is approaching the entryway. For
example, if the visitor is determined to be approaching the
entryway but does not enter the activity area surrounding a
package, only the approach determination is made. Further, if the
visitor enters the activity area surrounding a package but is not
determined to be approaching the entryway (e.g., if a package has
been delivered relatively far from the entryway), only the activity
area breach determination is made. In some implementations, an
activity area is defined from the location of any sensitive object
in proximity to the entryway (e.g., flowers, lawn ornaments, or any
other objects which the user may desire to protect from vandalism
or theft).
[0258] In some implementations, upon a determination that a visitor
is approaching the entryway, the method additionally includes
automatically switching from the camera that was used to obtain the
motion stream to a camera that is better situated to capture images
of the visitor's face, such as a doorbell camera. In some
implementations however, only one camera is used for both obtaining
the motion stream and capturing the visitor's face.
[0259] In some implementations, a length of the observation window
is predefined to correspond to a reasonable amount of time for the
visitor to complete the approach to the entryway, or to reach a
threshold distance to the entryway. For example, a visitor
approaching an entryway located at the end of a long walkway is
given more time to reach the entryway (or a threshold distance from
the entryway) than a visitor approaching an entryway located at the
end of a shorter walkway.
[0260] In some implementations, the method additionally or
alternatively includes initiating the observation window in
response to a determination that the visitor is within a threshold
distance to the entryway, where the threshold is predetermined
based on a layout of the entryway. In some implementations, the
observation window is initiated when the visitor is close enough to
the entryway to enable an interaction with the electronic greeting
system (e.g., a doorbell press or verbal communication). In some
implementations, the visitor is determined to have reached the
threshold distance to the entryway based on a range sensor, such as
a passive infrared ("PIR") sensor, or radar.
[0261] In some implementations, context information is based on a
detected announcement event (e.g., a doorbell press, a door knock,
a keypad entry, or a verbal announcement); a facial recognition
analysis; one or more behavior characteristics of the visitor; one
or more clothing characteristics of the visitor; a time of day
during which the visitor approaches the entryway; a verbal
announcement of the visitor; proximity in time to a prescheduled
event; proximity in time to a prescheduled status of the smart home
environment; a status or location of the user; and/or a timing of
the detected visitor action compared to a timing of the
identification of the motion event involving the visitor
approaching the entryway.
[0262] In some implementations, context information includes a
detected announcement event. Example announcement events include a
doorbell press, a door knock, a keypad entry, a remote-control
operation, or any other kind of active interaction between the
visitor and the electronic greeting system. In some
implementations, context information includes a lack of detected
announcement events (e.g., a visitor lingers by the entryway
without pressing the doorbell) for more than a predetermined
threshold of time. In some implementations, the announcement is
part of a pre-assigned pattern of events associated with a known
visitor (e.g., a personalized knock or doorbell ring pattern). In
some implementations, the announcement is a pre-assigned verbal
announcement associated with a known visitor. For these
implementations, an audio sensor (e.g., a microphone) detects an
audio signal and the processor performs an audio recognition
analysis to determine whether the verbal announcement matches any
known announcements stored in memory. In some implementations, the
audio recognition analysis determines whether the visitor's voice
matches a known voice stored in memory. In some implementations,
the audio recognition analysis determines whether the visitor's
words match a known pattern of words stored in memory (e.g., "It's
Matt," "I'm here for the barbeque," or "The password is
Bosco.").
[0263] In some implementations, context information includes
identity data based on a facial recognition analysis. In some
implementations, face images are stored in a database. In some
implementations, the user adds new face images to the database by
registering automatically cropped images of new faces from new or
previously unregistered visitors to the smart home environment. In
other implementations, the user adds new face images by registering
potential visitors independently of whether they are in a vicinity
of the entryway. For example, at a time or location not involving a
visit, the user may capture an image of a potential visitor's face
so that when the potential visitor visits the smart home
environment at a future time, the smart home environment will
recognize the potential user and provide appropriate context
information based on the facial recognition. In some
implementations, in addition or in the alternative to identity data
(e.g., "Matt is at the front door."), context information includes
a classification of the visitor (e.g., "A known visitor is at the
front door," or "An unknown visitor is at the front door.") based
on whether the visitor's face is recognized. For example, if the
visitor's face is recognized, the context information includes a
"known" status, and if the visitor's face is not recognized, the
context information includes an "unknown" status for the visitor.
Additionally or alternatively, the identity data or classification
data includes further description of the visitor based on a result
of the facial recognition analysis (e.g., "The pool cleaner is at
the front door.").
[0264] In some implementations, context information includes one or
more behavior characteristics of the visitor. For example, a
behavior characteristics includes holding an object (e.g., a
package, a clipboard, or any other object that suggests or
identifies a reason for the visitor's presence). As a further
example, a behavior characteristic includes lingering in an
activity area (e.g., an area defined by a threshold distance from
the entry way or from an object such as a delivered package) for a
time period greater than a predetermined threshold.
[0265] In some implementations, context information includes one or
more clothing characteristics of the visitor. For example, a
clothing characteristic includes a uniform (e.g., worn by a
delivery person). Further examples include clothing categories,
such as business clothing, casual clothing, and suspicious clothing
(e.g., an article of clothing covering the face, dark clothing
during night hours or in dark lighting conditions, and gang-related
clothing).
[0266] In some implementations, context information includes a time
of day during which the visitor approaches the entryway. For
example, a level of suspicion may be lower during the day and
higher at night. In some implementations, "day" and "night" are
differentiated by predetermined times. In other implementations,
"day" and "night" are differentiated by sensing an amount of light
in the field of view of the entry way. Sensing an amount of light
in the field of view is accomplished by, for example, using a light
sensor in proximity to the entry way, or by analyzing a brightness
level in the one or more frames of the motion stream. In some
implementations, visibility-based context information is weighted
based on intermediate amounts of brightness (e.g., during dusk and
dawn, or during cloudy days).
[0267] In some implementations, context information includes audio
data, such as a verbal announcement (examples of which are
described above). Further examples include background noise from
sources other than the visitor (e.g., a barking dog, a police
siren, or any other sound that may provide context for the
visit).
[0268] In some implementations, context information includes a
proximity in time to a prescheduled event. For example, a dog
walker may be scheduled to arrive at a prearranged time to pick up
the dog. A delivery person may be scheduled to deliver a package at
an expected time. A service person (or any other known person) may
be scheduled to arrive during an expected time or timespan (e.g.,
every Tuesday between 2-4 pm to clean the pool, the first Saturday
of each month to service the lawn, or a one-time visit arranged in
advance for any other purpose).
[0269] In some implementations, context information includes a
proximity in time to a prescheduled status of the smart home
environment. For example, the smart home environment may be
prescheduled to be unoccupied (i.e., the occupants are away),
between certain hours (e.g., between 9:00 am and 6:00 pm). As a
further example, the smart home environment may be in a
do-not-disturb mode (e.g., while a baby is sleeping, or during
quiet hours during which the occupants wish to be left alone).
[0270] In some implementations, context information includes a
status or location of the user. Example user statuses include a
do-not-disturb status, an away status, and/or an at-home status. In
some implementations, a location sensor of the client device
provides user location information to the electronic greeting
system. In other implementations, the user manually notifies the
electronic greeting system of the user's location and/or
status.
[0271] In some implementations, context information includes any
combination of the above examples. In some implementations,
individual subsets of context information are weighted, and the
context information is a weighted combination of the individual
subsets of context information. For example, brightness information
or time-of-day information may be weighted more heavily than
identity information (e.g., if the pool cleaner approaches the
entryway in the middle of the night, the time-of-day information is
more relevant in determining contextual information for the
approaching visitor, and is therefore more heavily weighted).
[0272] In some implementations, the observation window ends at the
earlier of: (1) a visitor announcement (e.g., a doorbell press or
knocking event); and (2) a predetermined time threshold (e.g., the
visitor has lingered for more than the predetermined time threshold
without making an announcement). In some implementations, the
predetermined time threshold is dynamic, and it depends on the
context information (e.g., longer observation windows when the
context information suggests a higher level of safety or concern,
and shorter observation windows when the context information
suggests a lower level of safety or concern).
[0273] Some implementations include a method of interacting with a
visitor to a smart home environment via an electronic greeting
system of the smart home environment. In some implementations, the
method includes: (1) obtaining motion data from a sensor of the
smart home environment; (2) identifying, based on analysis of the
motion data, a motion event involving a visitor; (3) obtaining
context information from the smart home environment for the motion
event; (4) based on the context information, identifying a
plurality of appropriate actions available to a user of a client
device for interacting with the visitor via the electronic greeting
system; and (5) causing the identified actions to be presented to
the user of the client device.
[0274] In some implementations, obtaining motion data includes
analyzing a plurality of image frames to determine whether motion
between two or more frames of the plurality of frames satisfies
motion criteria. In some implementations, pixel motion is compared
between subsequent frames. In other implementations, image
differencing is performed between a current frame and a reference
image.
[0275] In some implementations, obtaining motion data includes
analyzing infrared data from an infrared sensor (e.g., a PIR
sensor) to determine whether a difference in infrared data
satisfies motion criteria. In some implementations, obtaining
motion data includes analyzing data from a motion sensor to
determine whether the motion data satisfies motion criteria.
[0276] In some implementations, identifying the motion event
includes detecting the visitor entering an activity area (defined
above) in proximity to the entryway, detecting a face of the
visitor and/or detecting at least one of a height, shape, and
movement characteristic of the visitor, as described above.
[0277] In some implementations, identifying the motion event
includes any of the determinations described above relating to a
visitor approaching the entryway or entering an activity area. In
other words, when the electronic greeting system determines that a
visitor is approaching the entryway or entering an activity area, a
motion event is triggered.
[0278] In some implementations, obtaining context information from
the smart home environment for the motion event includes obtaining
any of the context information described above. In other words,
when a motion event is identified or triggered, any of the context
information described above is obtained by the electronic greeting
system.
[0279] Based on the context information, the electronic greeting
system identifies a plurality of appropriate actions available to a
user of the client device for interacting with the visitor via the
electronic greeting system. An action is defined as "appropriate"
if it is relevant, applicable, useful, pertinent, and/or suitable
for responding to the visitor depending on the context information.
In some implementations, a collection of actions is stored in a
database and ranked in terms of their applicability, relevance,
and/or usefulness to a present situation involving a specific
visitor and specific context information. The ranked actions are
then ordered based on the ranking. In these implementations, an
action is defined as "appropriate" if it is ranked relatively
higher than another action. In some implementations, the higher an
action is ranked, the more appropriate the action is considered to
be. In some implementations, an action is defined as "appropriate"
if its rank is above a predetermined threshold (e.g., the ten
highest ranked actions), with a subset of appropriate actions
(e.g., three actions) being presented to the user. In other
implementations, the threshold is determined based on a number of
actions that can be presented to the user in a single user
interface of the client device (e.g., if the user interface can
only display three actions at once, then the three highest ranked
actions are determined to be "appropriate"), and all of the
appropriate actions are simultaneously presented to the user in the
same user interface. In some implementations, a number of actions
to be presented to the user is based on an amount of space
available in a quick action area of a user interface of the client
device.
[0280] In some implementations, appropriate actions include one or
more communication-based actions. In some implementations, the
electronic greeting system speaks to the visitor using a
synthesized voice. In other implementations, the electronic
greeting system outputs a pre-recorded message to the visitor,
recorded in advance by the user. Examples of communication-based
actions include communicating a message to the visitor regarding a
status of the user (e.g., "Matt is busy," or "Matt will be right
there"); communicating a message to the visitor directing the
visitor to perform an action (e.g., "Please leave the package,"
"Come back later," or "Come in and take the dog"); communicating a
customized message to an expected or unexpected visitor, such as a
response to a salesperson (e.g., "Sorry, we are not interested"), a
greeting (e.g., "Welcome, please join us in the backyard"), or a
prompt (e.g., "Should I contact the Homeowner?" or "What is the
password?"); and communicating a message to the visitor directing
the visitor to leave a message for the user. In some
implementations, if a visitor leaves a message for the user, the
electronic greeting system sends the message to the user's device.
If the user is monitoring the client device, the user can watch
and/or listen to the message as the message is being received.
Otherwise, the message is recorded, by the client device or by the
electronic greeting system, for future retrieval by the user. In
some implementations, the electronic greeting system identifies the
user to the visitor by referring to the user's name, or by using a
generic placeholder (e.g., "Homeowner"), depending on the obtained
context information. For example, if the visitor is known, the
electronic greeting system uses the user's name, but if the visitor
is unknown, the electronic greeting system refers to the user by a
generic placeholder. In some implementations, the electronic
greeting system refers to the user by name (e.g., if the user is
known). In some implementations, the electronic greeting system
refers to the user by other descriptive attributes (e.g., "Hello,
person in the red hoody") depending on the context information
(e.g., if the user is away, a package is left by the entryway, and
an unknown visitor enters an activity area around the packer, the
system communicates to the visitor that the visitor is
recognized).
[0281] In some implementations, customized messages are
preprogrammed, allowing the user to select them from a list. In
other implementations, a customized message is communicated through
the client device in real time. For example, the user composes a
customized message at the client device by directly entering a text
message or by using a speech-to-text application of the client
device. The user-composed message is then converted to an audio
message by a text-to-speech application at the electronic greeting
system, and the audio message is communicated to the visitor
through a speaker located near the entryway. In some
implementations, the visitor's response is recorded and converted
to a text message by a speech-to-text application at the electronic
greeting system or at the client device, and the text message is
presented to the user through a user interface of the client
device. In some implementations, the visitor's message is
transmitted in an audio format to the client device, and presented
to the user as an audio message. In some implementations, if the
visitor speaks in a language that the user does not understand, or
vice versa, the messages are translated by a translation
application at the electronic greeting system or at the client
device.
[0282] In some implementations, in addition or in the alternative
to an audio communication, the electronic greeting system presents
a visual communication to the visitor, such as an video message
recorded by the user at the client device, a preprogrammed video
message, or a visual representation of the user's text messages. In
some implementations, the visual communication is presented to the
visitor on a display mounted near the entryway.
[0283] In some implementations, appropriate actions include one or
more action-based actions. Examples of action-based actions include
adjusting a security level of the smart home environment (e.g.,
locking or unlocking a door, adjusting the brightness level of one
or more lights in the entryway or one or more lights in other areas
of the smart home environment by dimming them or turning them on or
off, adjusting an alarm sensitivity level); alerting law
enforcement personnel (e.g., calling 911); alerting a preselected
contact of the user (e.g., a trusted neighbor or a neighborhood
watch contact); capturing image or video data of the visitor and
recording it, sending it to the authorities, or sending it to the
preselected contact of the user; or turning on an alarm of the
smart home environment.
[0284] In some implementations, appropriate actions include one or
more person-specific actions. Examples of person-specific actions
include actions that are based on a detected identity of the
visitor (e.g., detected based on facial recognition, a personalized
doorbell push-button pattern, a personalized keypad passcode, or
other examples discussed above); whether the visitor is classified
as known or unknown (e.g., "Come around to the back" vs. "Please
wait for assistance"); whether the visitor is expected or
unexpected (e.g., "Come in and take the dog" vs. "You appear to be
early for the dog walking appointment"); or what the visitor is
doing (e.g., present in an activity area without announcing,
entering an activity area when there is a package, or lingering
near the entryway for longer than a threshold). In some
implementations, a visitor who is classified as having an unknown
identity can still be classified as being an expected visitor based
on other factors, such as a uniform (e.g., denoting a pool cleaning
or dog walking service) or an object carried by or accompanying the
visitor (e.g., pool cleaning equipment or a dog leash).
[0285] In some implementations, appropriate actions include one or
more location-specific actions. Examples of location-specific
actions include actions that depend on a location of the entryway,
such as a first subset of actions for a front door (e.g.,
communication-based greetings) versus a second subset of actions
for a back door or an internal door (e.g., action-based security
functions, such as sounding an alarm).
[0286] In some implementations, appropriate actions include one or
more building-specific actions. Examples of building-specific
actions include actions that are based on whether the smart home
environment is a residential house, condo, or apartment (e.g.,
having home and away hours and various residential-based actions),
or a workplace (e.g., having open and closed hours and various
workplace-based actions). Further examples of building-specific
actions include actions that are based on a relative safety level
of the neighborhood or geographic area in which the smart home
environment is located (e.g., communication-based greetings for
safe areas vs. action-based security functions for unsafe
areas).
[0287] In some implementations, appropriate actions include one or
more user disposition-specific actions. Examples of user
disposition-specific actions include actions for users who feel
unsafe (e.g., a user who is home alone in an unsafe neighborhood
may wish to have quicker access to action-based security
functions), and actions for users who merely wish to monitor
visitors (e.g., a user who is at work and merely wishes to monitor
home deliveries may wish to have quicker access to
communication-based greetings).
[0288] As discussed above, the electronic greeting system
identifies a plurality of appropriate actions available to the user
of a client device for interacting with the visitor via the
electronic greeting system. In some implementations, the
identification is based on an ordered ranking of actions based on
the context information. In some implementations, the
identification is further based on customized user preferences for
different situations (e.g., a user may decide to always have the
alarm action quickly available when home alone, as discussed
above). The electronic greeting system proceeds to cause the
identified actions to be presented to the user of the client
device. In some implementations, a number of actions to be
presented to the user is based on an amount of space available in a
quick action area of a user interface of the client device. In some
implementations, an amount of space taken up by the quick action
area of the user interface is proportional to the size of the user
interface. For example, for client devices that have relatively
large screens, the quick action area of the user interface is more
spacious, thereby allowing for more actions to be presented to the
user, compared to client devices that have relatively smaller
screens. In some implementations, a size of the quick action area
of the user interface (and, therefore, the number of actions that
can be simultaneously presented to the user) is customizable by the
user.
[0289] The electronic greeting system is further configured to
receive a selection of an identified action from the user of the
client device, and cause the action to be performed. In some
implementations, the system can accept a request by the user to
display subsequent pluralities of appropriate actions if the user
has not found a desired action. In some implementations, the system
learns from past user selections of appropriate actions and adjusts
future rankings of actions with similar context information
accordingly. In some implementations, the system if further
configured to receive a selection of an identified action from the
user of the client device during a contemporaneous one-way or
two-way audio communication session facilitated by the client
device between the user and the visitor. In other words, for
instances in which the user is having an audio conversation with
the visitor and wishes to select an appropriate action during the
conversation, the system allows the user to select an action (e.g.,
unlock the door, or take a picture) without having to leave the
audio conversation.
[0290] In some implementations, the electronic greeting system is
further configured to present an updated subset of actions to the
user in accordance with new context information observed after an
initial subset of actions has been presented to the user. For
example, an initial subset of actions may include a
communication-based actions (e.g., a greeting) and an action-based
security action (e.g., sound an alarm). If the user sends a
greeting and the visitor responds with identifying information
(e.g., by showing credentials, looking more directly into the
camera, or entering a passcode into a keypad), the electronic
greeting system may present an updated subset of actions which are
purely communication-based (e.g., a plurality of replies to the
visitor's response). On the other hand, if the visitor fails to
respond to a greeting, the electronic greeting system may present
an updated subset of actions which are purely action-based (e.g.,
sounding an alarm or calling the authorities).
[0291] Although some of various drawings illustrate a number of
logical stages in a particular order, stages that are not order
dependent may be reordered and other stages may be combined or
broken out. While some reordering or other groupings are
specifically mentioned, others will be obvious to those of ordinary
skill in the art, so the ordering and groupings presented herein
are not an exhaustive list of alternatives. Moreover, it should be
recognized that the stages could be implemented in hardware,
firmware, software, or any combination thereof.
[0292] The foregoing description, for purpose of explanation, has
been described with reference to specific implementations. However,
the illustrative discussions above are not intended to be
exhaustive or to limit the scope of the claims to the precise forms
disclosed. Many modifications and variations are possible in view
of the above teachings. The implementations were chosen in order to
best explain the principles underlying the claims and their
practical applications, to thereby enable others skilled in the art
to best use the implementations with various modifications as are
suited to the particular uses contemplated.
