FIELD OF THE INVENTION
[0010] The invention relates generally to communications and
computer systems.
BACKGROUND OF THE INVENTION
[0011] People communicate in many ways over many types of devices
and channels, including by voice, by audio/video, and by text or
the like. Voice communications include audio over landline
telephones such as connected to POTS (plain old telephone service)
lines or PBX (private branch exchange) lines, and cellular and
satellite telephones, as well as voice over Internet Protocol
(VoIP). Audiovisual communications include video tele-conference
(VTC), which also may be Internet Protocol-based communication.
Text communications include electronic mail, instant messaging,
pagers with text messaging, and so forth.
[0012] Some contemporary devices provide multiple ways to
communicate, e.g., pocket sized personal computers may have a
cellular telephone connection to place audio calls, and a wireless
internet connection for sending and receiving electronic mail
messages and instant messaging communications. Some mobile devices
(e.g., a Smartphone) are considered to be more like telephones, but
likewise provide Internet access, and may handle text messaging
generally.
[0013] While all of these technologies are fairly easy to use, from
the user's perspective there is still a substantial emphasis on the
communication channels and protocols, and the devices themselves,
rather than on what is really important to the user, which is
communicating with someone else over an available device. For
example, a user who needs to talk to someone else may need to
consider many factors before selecting a device and attempting to
call the other person, such as whether to use a landline phone or a
mobile telephone, e.g., because the call may take a long time, part
of which could be spent while traveling. Other factors that a user
may consider include the other device that the caller should be
calling (whether to call the recipient's landline telephone or
mobile telephone), the cost of the call, whether the call should be
a video call, and so forth. Each of the devices in turn has its own
idiosyncrasies, such as a custom user interface, a different set of
stored numbers from those stored in other devices, and so
forth.
[0014] What is needed is an automated architecture (system) and
related methods for hiding much of the device and connection
considerations from users, and replacing those considerations with
a model that focuses on the user's real time communication with one
or more other users. The method and system should be flexible and
extensible to handle many user scenarios and usage patterns, yet
straightforward for users to implement.
SUMMARY OF THE INVENTION
[0015] Briefly, the present invention provides a system and method
for improved real-time communications leveraging a personal
computer and/or other processing resources, in which the boundaries
between various devices and communication channels are blurred, as
are the boundaries between types of communication, including voice,
text and video. The channel on which an incoming call is being
received, as well as the device on which the call may be answered,
are made significantly less important to the user than the fact
that a call is coming in from another party. Outgoing calls focus
on connecting to the called party, rather than any particular
device.
[0016] When connected, the user may easily move between modalities,
including switching devices on which the user is communicating, and
transitioning between types of communication. For example, two or
more users may connect with voice only communication, and then,
with relatively little effort, one or more may move to voice and
video. One or more users may employ instant messaging (IM) or
similar text communication, such as to enhance an existing
connection, or to avoid receiving a voice call but still respond in
some manner.
[0017] To provide such real-time communications functionalities, a
computer system includes various integrated communications-related
devices, such as an attached camera, an attached telephone handset,
and an attached speaker and microphone, which may function as a
speakerphone. Other devices include mobile communications devices
such as a cellular telephone or other mobile computing device. An
auxiliary display device such as for displaying caller ID data is
coupled to the computer, but may remain functional when the
computer operating system is not running. Buttons related to
controlling real-time communications, and indicators related to the
state of real-time communications are also provided.
[0018] The present invention provides a real-time communications
architecture including a controller comprising software that
facilitating communications in general, switches communications to
and from appropriate devices, and/or transitions communications
among the various communications channels and/or types of
communications. For example, the real-time communications
controller couples the communication devices to voice over IP,
video, POTS, PBX, cellular networks and virtually any
communications medium. The devices may be wired to the computer
system to which the real-time communications controller software is
running, or may be wireless, e.g., Bluetooth.TM. based devices. The
user may interact with the real-time communications controller
through user interface software of one or more programs, and/or
user interface software of the real-time communications controller,
but in one implementation, may also do so without running user
interface software. To this end, the real-time communication
control buttons are easy to use and understand, and along with the
indicators are positioned at locations that intuitively facilitate
interaction with the real-time communications controller.
[0019] In general, the user is able to input data via any input
mechanism, e.g., any microphone on any device, via any text or
pointing-based user data entry mechanism such as the keyboard
and/or mouse, and/or the camera. Similarly, the real-time
communications controller is able to receive data and output
appropriate data to the user on any of the output mechanisms when
activated, such as the speaker of a speakerphone, the handset
telephone, a headset, the mobile phone or similar computing device,
a PBX phone and/or a network card. Video, graphical and/or text
information can also be displayed on the main display and/or the
auxiliary display when available.
[0020] By responding to the user's actions, mode control logic in
the real-time communications controller follows various real-time
communication rules and user-configured settings to handle a users
communication needs, and in one implementation, can do so when the
computer system is otherwise powered down. The mode control logic
also appropriately responds to external events, such as incoming
calls, pages, text messages, forwarded voicemail messages, and so
forth. User actions may comprise lifting or replacing the attached
handset, typing and pointing-and-clicking a mouse or the like into
a user interface, pressing phone controls buttons, issuing voice
commands, and so forth.
[0021] The real-time communications controller also follows various
real-time communication rules and user-configured settings to
handle incoming calls in a manner that matches a users
communication needs. For example, for an incoming call, the mode
control logic will display the caller ID information, sound a ring
or call waiting tone on the speaker as appropriate, and respond to
a user action such as selection of a device to answer the call by
routing the voice, text and/or video as appropriate. Any other
audio may be automatically muted until no calls remain.
[0022] The present invention allows a user to switch devices,
transition between communication channels, and transition between
types of calls. Thus, for example, a user can answer a cellular
phone call via the headset, handset or speakerphone, add video to a
call when available, switch a POTS call to a cell-phone carrier,
and vice-versa.
[0023] Improved caller ID navigation is also provided, in which a
user can switch among parties on hold, and also conference in
multiple parties, in a non-linear manner. A user can use any active
display device such as the auxiliary display to perform such
operations.
[0024] Other advantages will become apparent from the following

DETAILED DESCRIPTION
Exemplary Operating Environment
[0037] FIG. 1 illustrates an example of a suitable computing system
environment 100 on which the invention may be implemented. The
computing system environment 100 is only one example of a suitable
computing environment and is not intended to suggest any limitation
as to the scope of use or functionality of the invention. Neither
should the computing environment 100 be interpreted as having any
dependency or requirement relating to any one or combination of
components illustrated in the exemplary operating environment
100.
[0038] The invention is operational with numerous other general
purpose or special purpose computing system environments or
configurations. Examples of well known computing systems,
environments, and/or configurations that may be suitable for use
with the invention include, but are not limited to: personal
computers, server computers, hand-held or laptop devices, tablet
devices, multiprocessor systems, microprocessor-based systems, set
top boxes, programmable consumer electronics, network PCs,
minicomputers, mainframe computers, distributed computing
environments that include any of the above systems or devices, and
the like.
[0039] The invention may be described in the general context of
computer-executable instructions, such as program modules, being
executed by a computer. Generally, program modules include
routines, programs, objects, components, data structures, and so
forth, which perform particular tasks or implement particular
abstract data types. The invention may also be practiced in
distributed computing environments where tasks are performed by
remote processing devices that are linked through a communications
network. In a distributed computing environment, program modules
may be located in local and/or remote computer storage media
including memory storage devices.
[0040] With reference to FIG. 1, an exemplary system for
implementing the invention includes a general purpose computing
device in the form of a computer 110. Components of the computer
110 may include, but are not limited to, a processing unit 120, a
system memory 130, and a system bus 121 that couples various system
components including the system memory to the processing unit 120.
The system bus 121 may be any of several types of bus structures
including a memory bus or memory controller, a peripheral bus, and
a local bus using any of a variety of bus architectures. By way of
example, and not limitation, such architectures include Industry
Standard Architecture (ISA) bus, Micro Channel Architecture (MCA)
bus, Enhanced ISA (EISA) bus, Video Electronics Standards
Association (VESA) local bus, and Peripheral Component Interconnect
(PCI) bus also known as Mezzanine bus.
[0041] The computer 110 typically includes a variety of
computer-readable media. Computer-readable media can be any
available media that can be accessed by the computer 110 and
includes both volatile and nonvolatile media, and removable and
non-removable media. By way of example, and not limitation,
computer-readable media may comprise computer storage media and
communication media. Computer storage media includes volatile and
nonvolatile, removable and non-removable media implemented in any
method or technology for storage of information such as
computer-readable instructions, data structures, program modules or
other data. Computer storage media includes, but is not limited to,
RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM,
digital versatile disks (DVD) or other optical disk storage,
magnetic cassettes, magnetic tape, magnetic disk storage or other
magnetic storage devices, or any other medium which can be used to
store the desired information and which can accessed by the
computer 110. Communication media typically embodies
computer-readable instructions, data structures, program modules or
other data in a modulated data signal such as a carrier wave or
other transport mechanism and includes any information delivery
media. The term "modulated data signal" means a signal that has one
or more of its characteristics set or changed in such a manner as
to encode information in the signal. By way of example, and not
limitation, communication media includes wired media such as a
wired network or direct-wired connection, and wireless media such
as acoustic, RF, infrared and other wireless media. Combinations of
the any of the above should also be included within the scope of
computer-readable media.
[0042] The system memory 130 includes computer storage media in the
form of volatile and/or nonvolatile memory such as read only memory
(ROM) 131 and random access memory (RAM) 132. A basic input/output
system 133 (BIOS), containing the basic routines that help to
transfer information between elements within computer 110, such as
during start-up, is typically stored in ROM 131. RAM 132 typically
contains data and/or program modules that are immediately
accessible to and/or presently being operated on by processing unit
120. By way of example, and not limitation, FIG. 1 illustrates
operating system 134, application programs 135, other program
modules 136 and program data 137.
[0043] The computer 110 may also include other
removable/non-removable, volatile/nonvolatile computer storage
media. By way of example only, FIG. 1 illustrates a hard disk drive
141 that reads from or writes to non-removable, nonvolatile
magnetic media, a magnetic disk drive 151 that reads from or writes
to a removable, nonvolatile magnetic disk 152, and an optical disk
drive 155 that reads from or writes to a removable, nonvolatile
optical disk 156 such as a CD ROM or other optical media. Other
removable/non-removable, volatile/nonvolatile computer storage
media that can be used in the exemplary operating environment
include, but are not limited to, magnetic tape cassettes, flash
memory cards, digital versatile disks, digital video tape, solid
state RAM, solid state ROM, and the like. The hard disk drive 141
is typically connected to the system bus 121 through a
non-removable memory interface such as interface 140, and magnetic
disk drive 151 and optical disk drive 155 are typically connected
to the system bus 121 by a removable memory interface, such as
interface 150.
[0044] The drives and their associated computer storage media,
discussed above and illustrated in FIG. 1, provide storage of
computer-readable instructions, data structures, program modules
and other data for the computer 110. In FIG. 1, for example, hard
disk drive 141 is illustrated as storing operating system 144,
application programs 145, other program modules 146 and program
data 147. Note that these components can either be the same as or
different from operating system 134, application programs 135,
other program modules 136, and program data 137. Operating system
144, application programs 145, other program modules 146, and
program data 147 are given different numbers herein to illustrate
that, at a minimum, they are different copies. A user may enter
commands and information into the computer 110 through input
devices such as a tablet, or electronic digitizer, 164, a
microphone 163, a keyboard 162 and pointing device 161, commonly
referred to as mouse, trackball or touch pad. Other input devices
not shown in FIG. 1 may include a joystick, game pad, satellite
dish, scanner, or the like. These and other input devices are often
connected to the processing unit 120 through a user input interface
160 that is coupled to the system bus, but may be connected by
other interface and bus structures, such as a parallel port, game
port or a universal serial bus (USB). A monitor 191 or other type
of display device is also connected to the system bus 121 via an
interface, such as a video interface 190. The monitor 191 may also
be integrated with a touch-screen panel or the like. Note that the
monitor and/or touch screen panel can be physically coupled to a
housing in which the computing device 110 is incorporated, such as
in a tablet-type personal computer. In addition, computers such as
the computing device 110 may also include other peripheral output
devices such as speakers 195 and printer 196, which may be
connected through an output peripheral interface 194 or the
like.
[0045] The computer 110 may operate in a networked environment
using logical connections to one or more remote computers, such as
a remote computer 180. The remote computer 180 may be a personal
computer, a server, a router, a network PC, a peer device or other
common network node, and typically includes many or all of the
elements described above relative to the computer 110, although
only a memory storage device 181 has been illustrated in FIG. 1.
The logical connections depicted in FIG. 1 include a local area
network (LAN) 171 and a wide area network (WAN) 173, but may also
include other networks. Such networking environments are
commonplace in offices, enterprise-wide computer networks,
intranets and the Internet. For example, in the present invention,
the computer system 110 may comprise source machine from which data
is being migrated, and the remote computer 180 may comprise the
destination machine. Note however that source and destination
machines need not be connected by a network or any other means, but
instead, data may be migrated via any media capable of being
written by the source platform and read by the destination platform
or platforms.
[0046] When used in a LAN networking environment, the computer 110
is connected to the LAN 171 through a network interface or adapter
170. When used in a WAN networking environment, the computer 110
typically includes a modem 172 or other means for establishing
communications over the WAN 173, such as the Internet. The modem
172, which may be internal or external, may be connected to the
system bus 121 via the user input interface 160 or other
appropriate mechanism. In a networked environment, program modules
depicted relative to the computer 110, or portions thereof, may be
stored in the remote memory storage device. By way of example, and
not limitation, FIG. 1 illustrates remote application programs 185
as residing on memory device 181. It will be appreciated that the
network connections shown are exemplary and other means of
establishing a communications link between the computers may be
used.
Real Time Communications Modality Blurring
[0047] The present invention is generally directed towards blurring
various communications modalities, such that a user communicates
with one or more other users typically without having to deal with
the connection channel or any particular device considerations. For
example, audio, video and text communications will be initiated by
the user using any suitable device that the user has available and
wants to use, regardless of the channel (or channels) on which the
communication ultimately occurs. Similarly, received communications
can be handled by any appropriate device that the user selects. As
will be understood, the various channels, devices and scenarios
described herein are only examples, and there are many others to
which the present invention will apply.
[0048] Turning to FIG. 2 of the drawings, there is shown a computer
system, such as the computer system 110 of FIG. 1, in which various
communications-related devices are integrated. For example, the
computer system 110 includes a monitor 191 having an attached
camera 202, an attached telephone (e.g., handset) 204, and an
attached speaker 206, which along with a microphone 208, may
function as a speakerphone. Other devices not separately
represented in FIG. 2 include mobile communications devices such as
a cellular telephone or other mobile computing device capable of
connecting in some way (e.g., by wired cradle or Bluetooth.TM.
technology) with the computer system. Although shown as individual
devices in FIG. 2, it is understood that any or all of these
devices, such as the speaker 206 and microphone 208, may be
combined into a unitary assembly, or built into other devices, such
as the monitor 191. In any event, each of these devices may be
present and if so are connected directly or indirectly by a wired
or wireless connection to interfaces at the main PC housing 214
(containing at least the motherboard, but also typically containing
some non-volatile storage).
[0049] Also represented in FIG. 2 is an auxiliary display device
220, such as for displaying caller ID data or like information as
described below. The auxiliary display 220 is typically small
(relative to the main display screen 191), and may be the display
of another device, such as the screen of a mobile computing device,
but may also be a dedicated display, such as one that is operably
connected or coupled to the computer operating system when the
computer system 110 is in a powered-up state. The auxiliary display
may comprise a simple text display, such as a two-line display or
the like. Further, note that the auxiliary display need not be an
actual display, but can be a projection (e.g., onto a wall) of the
information. As will become apparent below, the auxiliary display
device 220 may provide some of its own processing and storage
resources, so as to remain functional to some extent when the
computer operating system is not running. In one alternative
implementation described below, the auxiliary display device 220
includes control buttons or the like thereon for interacting with
that display 220, and possibly with the computer system 110 in
general, as described below. The keyboard 162 and/or monitor 191
(and/or possibly the pointing device 161) may also include
non-conventional buttons 222, such as buttons related to
controlling real-time communications, and non-conventional LED
indicators 224, such as indicators related to the state of
real-time communications.
[0050] In accordance with an aspect of the present invention, as
generally represented in FIG. 3, the computer system 110 includes,
a real-time communications controller 300, primarily implemented in
a software component or set of software components, that
intelligently handles various aspects of a user's real-time
communication needs, including facilitating communications in
general, switching communications to and from appropriate devices,
and/or transitioning communications among the various
communications channels and/or types of communication. Note that
the real-time communications controller 300 need not be built into
the computer system 110, but can connect thereto as an add-on
device, such as via a USB connection.
[0051] To handle a user's various communications needs, the
real-time communications controller 300 allows a user to connect to
various communication channels (e.g., a telephone company switching
network, a mobile phone network, the internet or an intranet, and
virtually any other local area or wide area network over which
communication is possible) using the various communications-related
data input/output devices. In general, the user is able to input
data via any input mechanism, e.g., any microphone on any device,
via any text or pointing-based user data entry mechanism 302 such
as the keyboard and/or mouse, and/or the camera 202, and have that
data configured as appropriate (e.g., converted from speech to
text) and sent to an appropriate (one or possibly more) of the
available communication channels. Similarly, the real-time
communications controller 300 is able to receive data and output
appropriate data to the user on any one or more of the output
mechanisms, such as the speaker of a speakerphone 304 when the user
has selected that device, the handset telephone 204 when lifted, a
headset 306 if activated, the mobile phone or similar computing
device 308 if selected, a PBX phone 310 connected to a PBX
mechanism 312 and/or a network card 314. When video, graphical
and/or text information is available, data can also be displayed on
the main display 191 (if active), and/or the auxiliary display 220.
Note that some of the devices are represented in FIG. 3 as directly
connected (coupled) to the computer system while other are shown as
being wireless, however it is understood that any device may be
wired or wireless, e.g., a typical mobile computing device or
mobile telephone may be cradled and thus "wired" to the computer,
and/or may integrate a cellular phone, Wireless Ethernet (also
known as 802.11b or Wi-Fi), and/or Bluetooth.TM. wireless
technology. Further, any "connection" referred to herein and the
like should be considered equivalent to a "coupling," whether
directly or indirectly connected through any type of
intermediary.
[0052] In accordance with an aspect of the present invention, the
real-time communications controller 300 controls the communication
modes for the user, thereby removing much of the user's need to
deal with device and connection considerations. As generally
represented in FIG. 4, this is accomplished by responding to the
user's actions, via mode control logic 400 in the real-time
communications controller 300 that follows various real-time
communication rules 402 and/or is based at least in part on other
user-configurable settings and a current operating state 404. The
mode control logic 400 likewise responds to external events, such
as incoming calls, pages, text messages, forwarded voicemail
messages, and so forth.
[0053] User actions can occur and be detected in any number of
ways, and the present invention contemplates essentially any way of
providing user action data or intended action data to a computer
system. For example, such actions can include lifting or replacing
the attached handset, which correspondingly actuates a hook switch
408 that is connected to the real-time communications controller
300, and thus can be detected as state data. Phone controls 410,
such as in the form of buttons on a device such as a talk button or
buttons on the keyboard or monitor, (e.g., a speakerphone button, a
flash button, and so on) can similarly provide user action
information, as can a PBX telephone 310 or other computing
device/telephone 308 (FIG. 3) connected to the computer system.
Controls 420 accompanying the auxiliary display 220, such as in the
form of scroll buttons and possibly an enter or select button (or
equivalent button elsewhere on the system such as the flash
button), can also provide user action data, as can the computer
data entry mechanisms 302 such as a keyboard and mouse. Any
microphone, such as the microphone 208, can also provide user
action data, e.g., via speech recognition (command and control)
performed with a speech to text recognizer 430. Text may also be
converted to speech by an appropriate converter 432, such as when
the user enters text to leave a message, but instead actually
leaves a voice message on a called device, e.g., when the logic 400
detects that forwarding text would not be appropriate. User action
information may also be communicated by wireless radio 434, and/or
from a network connection or other communication channel. Motion
and/or proximity sensing can likewise serve as a user action
sensor.
[0054] Where appropriate, a graphical user interface component 440
shown as part of the mode control logic 400 (but possibly anywhere
in the computer system, such as in another application program) may
facilitate entry of the user action information. For example, the
user may interact with one of the displays to select a displayed
telephone number for connecting or reconnecting with a person or
device at that number.
[0055] The present invention similarly outputs information to the
user in any feasible manner, including via the user interface when
appropriate. Essentially, anything capable of outputting something
that can be sensed by a user can serve as an output mechanism,
including the displays 191 and/or 220, lights and other indicators
224, the speaker 206 or other audio generating device such as a
ringer on a cell phone, and other mechanisms such as one that
provides tactile feedback (e.g., a vibrating cell phone). Thus, as
used herein, the term "display" is only an example, and is not
limited to visible information, but can include any sensed output.
For example, a hook indicator in the form of an LED may be
configured to flash red to indicate an incoming call, be lit green
when off hook, blink amber when the call is on hold, and blink
on-and-off when a call is muted. A tone and pattern can "display"
the same information audibly.
[0056] In keeping with the present invention, the related hook
switch 408, controls 410, 420, displays 191 and 220 and indicators
224 provide additional value that is consistent with but go beyond
a user's past communications experiences. To this end, the various
controls and indicators are generally placed in proximity to the
functions that they control and represent. Further, the various
devices such as handsets, headsets, and speakerphones are already
familiar to users, and the physical interfaces for these devices
are largely equivalent to conventional devices.
[0057] Moreover, the present invention allows for various levels of
computing skill. In general, the various control buttons 410, 420
and the hook switch 408 that are provided allow the user to take
advantage of much of the real-time communications controller's
functionality without ever having to operate the graphical user
interface software 440. However, to accomplish more sophisticated
operations as desired, a user can also connect via the user
interface 440, e.g., to automatically dial calls, answer via a
mouse click, customize settings and preferences and so forth.
[0058] In general, the logic 400 receives user action data or
remotely communicated data (such as an incoming call), and based on
various real-time communications rules 402 and user configurable
settings 404, responds in a proper manner. For example, as
described below, for an incoming call, the mode control logic 400
will display the caller ID information on the auxiliary display
220, or possibly the main display 191 if so configured by the user,
sound a ring or call waiting tone on the speaker 206, and wait for
a user action. If the user presses a phone control button such as a
speakerphone button, the call will be connected to the appropriate
device, e.g., routed to the speaker 206 and microphone 208. Any
other audio, such as music that the user was listening to, may be
automatically muted until the call is complete, e.g., until the
user again presses the speakerphone button to disconnect.
[0059] The present invention thus automatically and transparently
responds in an appropriate manner to a user's needs. By way of
example, consider the example above of a user who is working at the
computer when a call comes in. Instead of figuring out what type of
call it is, finding the device necessary to (possibly) answer it,
and so on, the user merely glances at the auxiliary display,
decides whether to take the call, and if so, selects any
appropriate device to answer. Because the real-time communications
controller 300 is the center of communication, a call to any of the
user's landline telephone devices or any (smart) cellular telephone
will relay the caller ID data to the real-time communications
controller 300, which will display that caller ID data displayed on
the same auxiliary display 220 as any other call. For the same
reason, the user can answer any incoming call on the speakerphone
304, the handset 204, the headset 306, the cellular telephone or
mobile computing device 308 and so on. The user need not even know
whether a given call came in on a given communications channel,
such as the cellular channel instead of a POTS channel or network
channel, although for reasons such as cost of airtime, the user may
want to know this information. Regardless of the device and the
channel, the user is provided access to a universal address book,
call log, and inbox.
[0060] Moreover, the present invention allows a user to transition
between communication channels. Thus, for example, a user who
receives a POTS telephone call can answer talk for awhile, and
switch that call over to a mobile phone to continue the
conversation away from the computer system. Note that this is not
conventional call forwarding set up in advance for switching at the
central switching office or the like, but rather on-demand
transitioning during a telephone call. For example, rules 402 can
be set up to favor landline over cellular for local calls since
there is no airtime charge, however long distance may be favored
over cellular when there is no additional charge and the user is
likely to have unused airtime before the next billing cycle. Voice
over IP may be the most favored, but may not be available when the
computer system is powered down.
[0061] One simple way to accomplish transitioning live connections
is via a different telephone line relative to the source of the
call. For example, if a user is leaving his or her office, the
real-time communications controller 300 can transparently (or
mostly transparently) establish a cellular connection to the user's
mobile telephone device on that other line and connect the other
caller to that mobile telephone device through the real-time
communications controller 300. Voice over IP can similarly be
used.
[0062] Three-way and conference calling capabilities can also be
leveraged, e.g., a user can walk into his or her office while
connected to another person via a cell phone, the real-time
communications controller 400 can establish another call to the
other party via a POTS, PBX or voice over IP call, and when
connected, terminate the cellular phone call.
[0063] In addition to switching and transitioning among devices and
channels, the present invention can switch and/or transition among
types of communication. For example, a user can respond to a
telephone call with an instant message, either automatically or by
typing/speech recognition, e.g., to notify the caller that the call
was received but could not be answered at that moment. In the event
that the real-time communications controller 300 has the caller ID
and/or other information from that call, possibly including preset
knowledge such as that the incoming telephone number belongs to a
mobile device, the real-time communications controller 300 can
adjust the instant message as appropriate, e.g., convert a text
message to speech to leave a voice message when the call was known
to be from a mobile phone that does not handle text, or when the
user is known to be traveling. Note that the instant message does
not have to be sent to the same device that called the user, e.g.,
a user can respond to a received phone call from a conventional
telephone with an instant message to the caller's computer system.
A simple database lookup or the like by the mode control logic can
provide the recipient's address from the caller ID data so that the
user does not even have to enter this information.
[0064] As another type change, when available, the present
invention can start with an audio call and add video (one-way or
two-way) and/or instant messaging as desired by the parties, or
start with an instant message and add audio and/or video. For
example, a user can press a camera button, or select video via a
mouse click, to establish a video connection and start transmitting
video. A video call can similarly be transitioned to a non-video
(e.g., audio-only) call. In general, the present invention
facilitates switching and/or transitioning between any modes of
communication. Transitioning between text, voice and video states
is described below with reference to FIGS. 10-12.
[0065] It should be noted that the computer system need not be
fully operational for communications to work in accordance with the
present invention. Indeed, communications should still work when
the computer is powered down, at least to a default extent or to an
extent configured by a user, such as when the computer system is in
a sleep state or a hibernate mode, and/or when the user is locked
out of the system via security mechanisms. Note that the type and
extent of communications may be configured by the user. For
example, the user may want the telephone handset, speakerphone and
caller-ID device to work as conventional appliances when the
computer system is powered down, but not the camera, headset, or
network card. Further, the user may limit the extent of the
communications based on the computer system state, e.g., when the
user is not logged in, the real-time communications controller 300
may be set to block long distance calls, block calls to a certain
prefix, and so forth.
[0066] To enable and control communications in these powered down
modes, the real-time communications controller 300 may be loaded
into executable non-volatile memory, operated with a secondary
processor, and so forth, so that communications works as long as
some power is available, even though the disk, main processor, main
display, network card and/or other parts of the system are powered
down.
[0067] Turning to an explanation of the operation of the present
invention with particular reference to the mode control logic 400,
FIGS. 5-8 represent general logic and rules in the form of state
diagrams for various objects that control behavior of the various
mechanisms. For example, FIG. 5 shows the logic and rules for
connecting a call when initiating the call via a dialer object or
the like. As represented in FIG. 5, when starting in an idle state
500, the user will send a dial request to line device (FIG. 7). In
the event that the computer system is not powered-down, a dialer
program may be automatically displayed on the graphical user
interface (GUI) on the main display 191, from which the user may
enter a state where the user can select a person to call or close
the dialer, or the user may dial (or hang-up) in a conventional
fashion. A user may also be able to scroll through and select a
number on the auxiliary display 220, such as to call a number from
a list of calls logged via caller ID information, speak a name or
number into a microphone, press a speed dial button and so on. If
dialed in any manner, the logic will attempt to connect the call,
and if successful, the system will end up in a connected state 504
until terminated.
[0068] FIG. 5 also shows that a call answered (in any manner) when
in the idle state 500 goes directly to the connected state 504.
More particularly, a pick-up request is sent to the line device
(FIG. 7). If no receiver is active/off hook, a default (which may
be user-configurable) receiver is selected as the active receiver,
and the audio stream is sent to that active receiver. The call
event may be logged in the system.
[0069] When connected, if the connection supports video and a video
camera is present and its use is allowed, video is streamed. A user
may disallow video by closing the camera's shutter, or by
configuring the system to not automatically allow video, that is,
only allow video if some manual user action is detected. The user
can see when an incoming call supports video and can answer the
call immediately in that mode, such as by pressing a camera button.
Optionally, the user can set a preference so that the camera is
automatically enabled whenever answering a call that supports
video.
[0070] If the connection supports text or rich ink messaging, an
embedded instant messenger (IM) chat control is also enabled. If an
indicator serves as a "connection" light, i.e., to indicate when a
communication link is established between two users, then the
indicator may also indicate when an IM connection is active, such
as by a different LED behavior (e.g., color and/or flash pattern)
with respect to a voice-only call, to communicate to the user that
an IM connection exists.
[0071] FIG. 6 shows other operation of the logic 400, such as with
respect to an object that controls a ringer or other suitable
notification mechanism when an incoming call is received. When in a
ringer idle state 600, (which means idle with respect to notifying
a user of a new incoming call, and may include a state in which a
user is already on a current call), the logic 400 will look up and
display the new caller information and enter a waiting state 602.
For example, the waiting call may be displayed via a side bar
notification fly-out if the main display is on, and/or may be
displayed on the auxiliary display device. At that time, the logic
400 also may sound an audible alert (and/or providing another
suitable notification, such as flashing an LED and/or vibrating a
device). The type of alert may depend on whether the user is on
another call or on other state information, e.g., if in a Do Not
Disturb mode, no sound is played, else if no receiver is active, a
ringing sound is played, otherwise a receiver call waiting tone is
played.
[0072] If the active receiver goes off hook or is clicked, a flash
button or the like is pressed, or the user requests that the call
be answered via the graphical user interface, the ringer leaves the
waiting state 602 when the call is connected, after placing any
current call on hold. A conference button or the like (not shown)
can add the caller to an existing call. If no action is taken to
connect the call, a voice mail time out will send the call to voice
mail and return the ringer to the idle state with respect to
further incoming calls.
[0073] FIG. 7 shows the operation of the line device object in an
idle state 700, a waiting state 702, a connecting state 704 and a
connected state 706. In general, these states have been previously
described above in slightly different context, and will thus not be
repeated herein except to note that while attempting to establish a
connection as represented by state 704, a connecting status or the
like may be displayed by the line device object, during which time
the user can cancel the attempt. Also, a hold request can
transition the user from the connected state 706 to a waiting state
702 by placing the line on hold, while a pick-up request works in
the opposite way, by connecting the line. Also, not shown in FIG.
7, multimedia playback may be turned off or muted while any
receiver is active, and restored when no receiver is active. FIG. 8
represents the operation of a phone device object in an idle state
800, and in two off hook states, a normal state 802 and a muted
state 804. The transitions between the states are readily apparent
in FIG. 8, although it should be noted that as described above,
another receiver can be set as the active receiver without
disconnecting the line. For example, selecting a speakerphone
logically hangs-up an active handset or headset, picking up the
handset turns off the speakerphone or headset, pressing a talk
button on the headset turns off the speakerphone or handset, and so
forth.
[0074] FIG. 9 represents a general overview of the logic 400 that
summarizes various states of operation. For example, as represented
in FIG. 9, the hook switch operates in a number of ways, including
using it to terminate a call, lifting it to make a receiver active
and pick up waiting line, as a flash button to switch lines or
terminate a call if no lines are waiting. The hook switch may be
implemented as a cradle hook switch mechanically integrated into
the handset cradle, comprising a two-position toggle switch that
closes when the handset is off hook and opens when the handset is
in the cradle.
[0075] In general, as represented in FIG. 9 lifting the handset
from the cradle usually takes the handset off hook and displays a
dialog box for selecting the person to call. During a call,
replacing the handset in the cradle will hang up the call. If the
handset is not the active receiver during a call, lifting the
handset from the cradle will make the handset the active receiver,
switching off the old active receiver (e.g., the speakerphone or
headset). When the phone is ringing from an incoming call, lifting
the handset will answer the call, taking the handset off hook. If
the phone is ringing while another phone conversation is already in
progress, depressing the cradle hook switch quickly will toggle
between the two calls, like flashing the hook switch will do with
call waiting present on a legacy phone system. A talk button,
usually integrated into the keypad of telephone devices, such as a
headset or handset, performs similar functionality to the hook
switch and can generally be considered similar to the hook switch
operation in FIG. 9. In general, either a talk button or cradle
hook switch (or at least a graphical user interface equivalent) is
required for each phone handset or headset. The talk button
comprises a single-throw, momentary switch that toggles the hook
state for a telephone receiver. Its primary function is to initiate
or answer a call, and then hang up when the conversation is
finished. During a call, pressing a talk button on the active
receiver will hang up the call. Pressing the talk button on another
receiver will have the effect of making it the active receiver,
switching off the old active receiver (handset or headset). When
the phone is ringing from an incoming call, pressing the talk
button will answer the call, taking the receiver off hook. If the
phone is ringing while another phone conversation is already in
progress, pressing the talk button will toggle between the two
calls.
[0076] FIG. 9 also shows various operations via a speakerphone
button similarly comprising a single-throw, momentary switch to
toggle the hook state for a speakerphone. Its primary function is
to initiate or answer a call, and then hang up when the
conversation is finished. The speakerphone button is a special case
of the talk button, used where the incoming call is broadcast over
a speaker and audio is collected via a far field microphone. In a
cordless handset with speaker phone capabilities, it may be
important to indicate to the user that the speakerphone is active
to differentiate it from the handset talk switch.
[0077] If a virtual speakerphone is implemented using the
microphone and speakers that are already part of the PC system, a
speakerphone button may be located on the keyboard, e.g., to the
left of the main keyboard keys. This button usually takes the PC
speakerphone off hook and displays a dialog box for selecting the
person to call. During a call, pressing the speakerphone button
when the speakerphone is the active receiver will hang up the call.
If the speakerphone is not the active receiver, this will have the
effect of making it the active receiver, switching off the old
active receiver. When the phone is ringing from an incoming call,
pressing the speakerphone button will answer the call, taking the
speakerphone off hook. If the phone is ringing while another phone
conversation is already in progress, pressing the speaker phone
button will toggle between the two calls like flashing the hook
switch.
[0078] Because the talk button or speakerphone button state may not
be readily apparent to a user, a hook indicator may be used in
conjunction with a talk or speakerphone button, and, for example,
may be located adjacent or integrated into the talk button or
speakerphone button. The hook indicator may indicate state via
various colors and flash patterns, e.g., steady state unlit when
the receiver is on hook, steady state green when the receiver is
off hook, or steady state red when no service is available. A
flashing indicator, such as with a "wink" duty cycle can overlay
the steady state, e.g., a red wink overlay can indicate call
waiting, or an amber flash overlay can indicate a call holding. The
call waiting overlay indicator will continue to blink as long as
the user can pick up the phone to connect to the incoming caller,
even if the call is no longer ringing. This allows call screening
when callers are recording voice mail. The call holding overlay is
generally only needed when a dedicated hold indicator is not
present.
[0079] Although not specifically represented in FIG. 9, other
buttons may be provided. For example, a flash button, often used
for alternate line selection, generates a momentary on hook
condition for signaling purposes. When the user is notified of a
call waiting, pressing the flash button will place the current call
on hold and answer the incoming call. With calls on hold, pressing
the flash button places the current call on hold and picks up the
next call in the hold queue. A hold button places a current call on
hold by placing the current call into a call waiting state as
generally represented in FIG. 7, freeing the receiver to make
another call, answer an incoming call, or hang up to pick up on
another receiver. A conference button initiates a conference call,
in which pressing the conference button joins the current call with
one or more calls waiting on hold. Other buttons are feasible, such
as a button to immediately send an incoming call to voice mail.
Note that because the real time communications controller 300
handles the calls, conference calls can also be handled via the
graphical user interface 440, e.g., additional contacts or groups
of contacts can be clicked and dragged to a window to conference in
others.
[0080] FIG. 9 also represents a number of user interaction
scenarios with respect to real-time communications, including
handling an incoming call and making a call. As described above, to
make a phone call, the user lifts the handset or presses the talk
switch on the speakerphone or headset, and then dials a number.
Alternatively, the user may select a contact from the display 220
or graphical user interface 440, or employ voice dialing. When
initiating a call from the graphical user interface 440, such as
within the context of a communications application such as
Microsoft.RTM. Outlook, the user can initiate a phone call from any
standard contact object supported by an API. The operating system
takes the default receiver off hook and makes the connection using
a preferred or specified telecommunications service.
[0081] To answer a phone call, the user lifts the handset, presses
a speakerphone switch, or presses a talk switch headset (or on the
speakerphone). Before answering, the user has the ability to view
caller ID, and possibly other pertinent contact information
displayed with the notification message (on the main display or
auxiliary display), allowing the user to pre-screen the call.
Depending on preferences, the user can then choose to pick up the
call or transfer it to voice mail, which may include transferring
it to one of a plurality of custom or standard voice mail messages.
While the caller is recording voice mail, the user can monitor the
incoming recording and pick up the receiver, similar to a
traditional answering machine.
[0082] The examples below provide additional interaction detail for
common telephony functions, including an incoming call scenario,
wherein the real-time communications controller sounds the ringer
and blinks the talk button indicator, while using caller ID
information to display contact information. When the user presses
the talk button, a microphone button, camera button, or picks up
the handset, or presses the hook (talk) switch on the headset, the
real-time communications controller 300 may light an indicator for
the active receiver. The user receives the call, and can switch
among devices, e.g., to switch to the speakerphone, the user
presses the talk button or mic button; to switch to the video
speakerphone, the user presses the camera button; to switch to the
handset, the user picks it up (activating the hook switch); or to
switch to the headset, the user presses the hook (talk) switch on
the headset. A cell phone or mobile computing device may be
similarly used, even without actually switching the call to the
cellular network (which may require some additional user action).
When the user switches active receivers, the system disables the
previous receiver to prevent feedback, and updates indicators to
reflect the active receiver.
[0083] If the call supports video, the real-time communications
controller blinks the camera indicator. If the user presses the
blinking camera button, or automatic video is set by user
preference to automatically stream video when video is available,
the system opens the video monitor, lights the camera indicator,
and starts streaming video.
[0084] To mute a component, the user can take an appropriate
action. For example, to mute video and audio, the user presses the
camera button, whereby the real-time communications controller
blinks the audio and video indicators until the camera button is
pressed again or the call is terminated. To mute video only, the
user shuts the camera's privacy shutter, whereby the system
un-lights the video indicators and closes the A/V monitor, but
maintains the audio indicator. To mute speakerphone audio, the user
presses the microphone (speakerphone) button, whereby the real-time
communications controller blinks an appropriate indicator until the
button is pressed again or the call is terminated. To hang up, the
user presses the hook switch for the active receiver.
[0085] To place a call, the real-time communications controller 300
reacts when the user presses the talk button, picks up the handset,
or presses the hook switch on headset, by displaying a dialog box
for selecting the person to call. The system may also audibly ask
through the active receiver, such as when voice dialing is enabled,
as to who the user would like to call. The real-time communications
controller uses resulting input to select a contact from the dialog
box, and the user can query to search and can re-query to refine
the search, if necessary.
[0086] When the user makes a selection or acknowledges a match, the
real-time communications controller shows contact information for
the selected recipient and shows a status dialog box while the call
is connecting. When connected, the user can switch devices as
described above, and also switch modes, e.g., audio to video, and
so forth, with the indicators operating in the above-described
manner.
[0087] The user can also perform other communications-related
tasks, including checking voice mail and call screening. For
example, an indicator light may blink to indicate a voice mail,
whereby the user can user press a notification button causing the
real-time communications controller to enter a callback routine for
the highest priority notification. In case of voice mail or
priority email, this may open the user's unified In Box. Call
screening logic follows various rules, including showing caller ID
information and contact summary data until, after a preset number
of rings, the system stops the ringer and sends a voice mail
message to an incoming caller. If the call screening option is
enabled, the system echoes the incoming message to a system audio
output device (usually the speaker). If the user presses the hook
switch of any receiver, the system discards the message and
switches to real-time voice, otherwise, when the user hangs up or
after a certain time limit, the system stops blinking the talk
button indicator and files a voice message.
[0088] FIG. 10-12 generally show the relationships between instant
messaging, and/or voice communication states, with various incoming
and/or outgoing video states, and the various channel switching
transitions between these states. Note that although instant
messaging is used as an example in FIG. 10, any other type of
real-time text messaging is equivalent, including text messages
sent to pagers, and possibly electronic mail if relatively fast
enough to be considered real-time. One state represented in FIG. 10
is a no call state 1000 than can transition to various voice and/or
instant messaging states. As also represented in FIGS. 10-12, the
connected states can have automatic video active, or video can be
added (or ended) at any time by either party.
[0089] FIG. 10 represents the instant messaging states without
voice, including a state with no video 1002, and states with
incoming, outgoing and two-way video, states 1004, 1006 and 1008,
respectively. As is readily apparent, each user controls these
states by user actions or configured preferences for automatic
video operation. Note that voice can be added from these states, in
which event a new state will be entered as represented in FIG.
12.
[0090] FIG. 11 represents the voice without instant messaging
states, with similar video-related states of voice only, incoming,
outgoing and two-way video, states 1004, 1006 and 1008,
respectively. Note that instant messaging can be added from these
voice states, in which event a new state will be entered as
represented in FIG. 12.
[0091] FIG. 12 represents the states and transitions when both
instant messaging and voice are active, with transitions within the
same four possible video-related states of none, incoming, outgoing
and two-way video available. As can be seen in FIG. 12, the
communication may transition to a no instant messaging state (FIG.
11) or no voice state (FIG. 10), or no communication at all at
state 1000 of FIG. 10, based on straightforward actions of the
users who are communicating.
[0092] In accordance with another aspect of the present invention,
there is provided a caller ID navigation mechanism that allows
users to navigate a stack of calls in a non-linear manner. As
represented in FIG. 13, the available calls may be displayed on the
auxiliary display device 220, with the currently connected call
1302 indicated in some manner to differentiate it from the calls on
hold. As can be appreciated, richer information may be provided
depending on the amount of display area available, such as the
length of time the user was on hold, the type of connections that
are available and its current state (voice, video, instant message)
and so forth.
[0093] In general, the user presses the scroll buttons 1304 and
1306 to navigate to a call, such as represented by the dashed box
1410 in FIG. 14, and presses a select button 1308 to switch to the
call, as represented by the connected box 1502 moving relative to
its position in FIG. 13. Because the real-time controller 300, and
not a remote switch at the telephone is in charge, the switching
may be non-linear. Note that the scroll buttons are typically near
or part of the auxiliary display unit because the user will be
looking at the display, however the select button 1308 may be
another button located elsewhere, such as a flash button on the
keyboard, (as long as that button remains active while the computer
system is otherwise in a powered off state).
[0094] Further, if the main display is active, the user need not
scroll, but can instead simply select a call to switch two via a
point and click operation. Of course, the user can also scroll,
such as via keyboard cursor keys to highlight, and the Enter key to
select. Again, richer information may be provided, particularly
since the main display 191 will provide more display area relative
to the auxiliary display 220.
[0095] As represented in FIGS. 16 and 17, (which shows a richer set
of information), depending on the available buttons and their
meaning, conferencing by selecting users is also feasible. For
example, holding the select button while on a connected call, and
then scrolling through the list view, can keep any existing
connections connected, and releasing the select button can add (or
drop if already selected) another user. On the main display, more
elaborate schemes are available, e.g., to drag and drop other
parties into a "connected" window, right click on a list view
similar to that shown in FIGS. 16 and 17, and so forth.
[0096] As can be seen from the foregoing detailed description,
there is provided a real-time communications method and system for
handling the switching and transitioning between communications
modalities including switching devices, switching communication
channels and/or transitioning types of communications, e.g., audio,
video and text. The present invention facilitates user
communication by blurring the distinction between these various
modalities, allowing the user to focus on the communication rather
than the mechanisms for accomplishing the communication. The method
and system thus provide significant advantages and benefits needed
in contemporary computing and communications.
[0097] While the invention is susceptible to various modifications
and alternative constructions, certain illustrated embodiments
thereof are shown in the drawings and have been described above in
detail. It should be understood, however, that there is no
intention to limit the invention to the specific forms disclosed,
but on the contrary, the intention is to cover all modifications,
alternative constructions, and equivalents falling within the
spirit and scope of the invention.
