DETAILED DESCRIPTION OF THE DRAWINGS
[0028] Referring now to the drawings, FIGS. 1 and 2 illustrate
components of an ambulatory navigation system of the present
invention configured to provide directions to a selected
destination to a pedestrian. FIG. 1 illustrates a first station or
core station 10, and FIG. 2 illustrates a second station or a
navigation station 12 of the present invention. As shown in FIG. 1,
each core station 10 includes a processor 14 and an input device 16
coupled to the processor 14. The input device 16 is illustratively
any type of input device such as a key board, key pad, mouse, touch
screen, voice recognition, or other data recognition device. An
operator uses the input device 16 to select a desired destination
for the operator or another person.
[0029] Core station 10 further includes a display 18 and a speaker
20 coupled to the processor. In one embodiment, processor 14
displays a menu of destination options on display 18 for the user
to select using the input device 16. Processor 14 is coupled to a
memory 22 which stores information related to a plurality of
destinations. In addition, processor 14 of core station 10 may be
coupled to a communication network 24, if desired. Network 24 is
used to permit core station 10 to access other databases for
information related to destinations which may be selected. Network
24 can also be used to update memory 22 with possible destinations
to select.
[0030] The core station 10 is configured to generate an information
carrying member 26 which has information related to or identifying
the selected destination of the user. In the illustrated
embodiment, the core station 10 includes an output device 28
configured to provide the information carrying member 26 with the
specific information identifying the selected destination. In one
embodiment, the output device 28 is a magnetic stripe encoder. In
another embodiment of the present invention, the output device 28
is a bar code encoder. Yet another embodiment, the output device 28
is a smart card encoder. It is understood that the output device
may be any type of device for placing information on or in the
information carrying member 26.
[0031] In another embodiment of the present invention, an attendant
specifically stationed at a location, such as a main entrance of a
facility, communicates to the person and asks the desired
destination. The attendant then either produces the information
carrying member 26 based on the selected destination or retrieves a
pre-made information carrying member 26 which includes information
related to the selected destination.
[0032] Once the person has the information carrying member 26
having information related to the selected destination, information
carrying member 26 is used at one of a plurality of navigation
stations 12 to obtain directions either to another navigation
station 12 or to the selected destination. As shown in FIG. 2, each
navigation station 12 includes a processor 30 and a detector or
input device 32 coupled to the processor 30. The detector 32
configured to identify the information on or in the information
carrying member 26. The processor 30 uses the detected information
to identify the selected destination either directly, or using
information stored in memory 34 coupled to processor 30 or
information obtained over a communication network 24 from a remote
location.
[0033] Once the processor 30 determines the selected destination
for the person based on the identified information, processor 30
determines directions to the selected destination from the location
of the particular navigation station 12 or directions to another
navigation station 12 closer to the selected destination. The
navigation station 12 then provides the person with directions to
the selected destination or another navigation station 12 using
either display 36, speaker 38, or printer 40 coupled to processor
30. The processor 30 also identifies the selected destination on
the display 36, speaker 38 or printer 40 so that the person can
make sure that the directions are to the selected destination.
[0034] Therefore, in one embodiment the navigation system of the
present invention does not rely upon the person to manually
re-enter the selected destination at each navigation station 12.
Once the information carrying member 26 is obtained, the navigation
stations 12 automatically identify the information related to the
selected destination and then provide the person with directions as
discussed above. In the illustrated embodiments, the input device
or detector 32 is a magnetic stripe reader, a bar code reader, a
smart card reader, a receiver, or other detector which
automatically detects information on the information carrying
member 26.
[0035] Referring now FIG. 3, a more detailed example of an
embodiment of the ambulatory navigation system is disclosed. The
ambulatory navigation system 100 guides a person through a facility
by providing updated destination instructions at prominent
locations within the facility. Ambulatory navigation system 100 is
illustratively incorporated into a facility 102 such as a
healthcare facility, airport, professional office building, college
campus, shopping center, or the like. The system 100 can also be
used outdoors with core stations and navigation stations located at
selected places within the city.
[0036] Illustratively, healthcare facility 102 includes a main
entrance area 104 connected to a hallway 106. Hallway 106
intersects a second hallway 108. Hallway 108 includes an access
area to a bank of elevators 122 and intersects additional hallways
110, 112. The healthcare facility shown in FIG. 1 further includes
a first ward of rooms 114 which are numbered between 1000 to 3000,
a radiology department 116, a second ward of rooms 118 which are
numbered between 3001 to 6000, and an Emergency Care Unit 120.
[0037] Ambulatory navigation system 100 illustratively includes an
information carrying member 26 such as a set of key cards 126, at
least one core station 128, and a plurality of navigation stations
130. Generally, a visitor 124 enters main entrance area 104 of
healthcare facility 102 with the purpose of proceeding to a
specific destination, such as a patient room to visit a family
member. Visitor 124 is issued a key card 126 or other information
carrying member 26 discussed above at main entrance 104. The key
card 126 includes an information carrying member 133 containing
information about the specific destination in the facility 102 of
visitor 124. As visitor 124 proceeds through healthcare facility
102, key card 126 interacts with navigation stations 130a-130d to
provide visitor 124 with appropriate destination instructions to
the specific destination of visitor 124.
[0038] One embodiment of key card 126 is shown in FIG. 4A. Key card
126 illustratively includes a body member 132 which is made from an
inexpensive material, such as plastic. Key card 126 is similar to
room access key cards currently used by hotels. Body member 132
includes a designated area 134 which is a location to provide
information, such as emergency phone numbers, or advertising. The
ability to place advertisements on key card 126 reduces the costs
to the facility associated with the implementation and maintenance
of ambulatory navigation system 100. Any conventional methods can
be used to place information or advertising within area 134 of key
card 126, such as conventional printing or the application of
labels or stickers. In one embodiment, advertising and information
is embossed within area 134 on key card 126.
[0039] FIG. 4B shows one embodiment of the rear side of key card
126. In FIG. 4B, the information carrying member 133 of key card
126 is a magnetic strip 136 which stores information. Magnetic
stripe 136 is illustratively programmed by core station 128 to
include a destination code corresponding to the final destination
of visitor 124 as discussed above in reference to FIG. 1.
Additionally, magnetic stripe 136 is read by an associated magnetic
strip reader located on navigation stations 130 to communicate to
navigation station 130 the destination code stored on magnetic
strip 136 as discussed above in reference to FIG. 2.
[0040] FIG. 4C shows a second embodiment of the rear side of key
card 126. In FIG. 4C, the information carrying member 133 of key
card 126 is a bar code region 138 which contains a series of spaced
dark bars. The destination code is illustratively determined by the
width and spacing between the individual dark bars. Bar code region
138 is read by a bar code reader, such as an optical scanner,
located on each navigation station 130 to communicate to navigation
station 130 the destination code referenced by bar code region 138.
In one embodiment, bar code region 138 contains the destination
code, itself. In another embodiment, bar code region 138 is
associated with a destination code stored on the system 100. As
such, by reading bar code region 138, navigation station 130 is
provided a pointer to query system 100 for the associated
destination code.
[0041] It is contemplated that the information carrying member 133
of key card 126 is any system that which is capable of
communicating information to navigation station 130. Examples
include, re-radiating devices which emit a signal when queried by
an interrogation signal or punched cards. Information carrying
member 133 is also contemplated to be an active system, such as a
battery powered transmitter, which emits a coded signal that is
detected by navigation station 130. In another embodiment, the
information is a location number which is manually entered by the
visitor into navigation station 130.
[0042] In another embodiment, a double-sided key card 126 includes
information carrying members 133 on both the front and rear sides
of key card 126. The information carrying member 133 on the rear of
key card 126 illustratively includes a destination code associated
with the specific destination of visitor 124. The information
carrying member 133 on the front of key card 126 includes a
destination code associated with main entrance 104 of healthcare
facility 102. As such, the front of key card 126 is used to
navigate the visitor 124 from his specific destination back to main
entrance 104.
[0043] Alternatively, visitor 124 is issued two individual key
cards 126 at main entrance 104, each key card 126 containing one
information carrying member 133. The first key card 126 is used to
guide visitor 124 from main entrance 104 to his specific
destination, and the second key card 126 is used to guide visitor
124 from his specific destination back to main entrance 104.
[0044] In another embodiment, when the facility has only a single
appropriate or desired point of entrance, such as main entrance
104, visitor 124 is issued a single key card 126. In such a case,
navigation stations 130 include the capability of providing
appropriate destination instructions to main entrance 104 by the
activation of a return function, such as by depressing a button
located on navigation station 130 for directions back to the main
entrance. When the return function is activated, the navigation
station 130 automatically provides the appropriate destination
instructions to proceed to main entrance 104.
[0045] Referring to FIG. 5, an illustrated embodiment of core
station 128 is shown. A core station 128 may be placed at all
primary entrances and busy junctions, such as gift shops,
cafeterias, and the like within the facility. Core station 128 is a
programming unit which programs key card 126 or other information
carrying member 26 as discussed above. The core station 128 is
operated either by facility personnel or by visitor 124.
[0046] Core station 128 includes a directory member 143, either
computer-based or push button selection member 144, which allows
for the selection of a destination within the facility. The
directory is connected to a database which provides a listing of
the various destinations within the facility. The database is
either locally stored in a memory of core station 128 or is
retained on the facility network and accessed by core station 128.
As shown in FIG. 5, core station 128 includes a housing 140 which
contains an information output device 141. Additionally, core
station 128 includes a display 146, a name plate 148 and a speaker
150.
[0047] In FIG. 5 information output device 141 is illustratively a
key card slot 142 which interacts with the magnetic stripe 136 on
key card 126. If the information carrying member 133 of key card
126 is not magnetic strip 136 then key card slot 142 is replaced
with the appropriate output device such as discussed above with
reference to FIG. 1. For instance if key card 126 includes bar code
region 138 then output device is a bar code encoder and
printer.
[0048] When visitor 124 approaches core station 128, the specific
destination of visitor 124 is selected by using push button member
144. Once the destination is selected, key card 126 is passed
through key card slot 142. During the passage of key card 126
through slot 142, core station 128 encodes the magnetic stripe 136
on key card 126 with a code that relates to the specific
destination of visitor 124. Methods for encoding the key card 126
are well known in the art. In one embodiment, the destination
selected and programmed is displayed on display 146 as a method of
verifying that an error was not made. Also, the first set of
appropriate destination instructions are shown on display 146 to
provide visitor 124 with initial directions to his specific
destination.
[0049] In one embodiment, information carrying member 133 is
programmed to include a language indicator along with the specific
destination code. The language indicator indicates to navigation
station 130, in what language the appropriate destination
instructions are to be provided to the person. As such, ambulatory
navigation system 100 provides the flexibility needed for
facilities 102 located in regions with diverse populations.
[0050] Referring to FIG. 6, an illustrated embodiment of a
navigation station 130 is shown. Navigation station 130 is placed
at intersection points or other location within the facility. An
intersection point is a location within facility 102 where the
visitor 124 is required to make a choice on which direction to
proceed. For example, referring to FIG. 3, navigation station 130a
is placed at the intersection of hallway 106 and hallway 108;
navigation station 130b is placed at the intersection of hallway
108 and hallway 110; navigation station 130c is placed at the
intersection of hallway 108 and hallway 112; and navigation station
130d is placed at the bank of elevators 122.
[0051] Navigation station 130 of FIG. 6 includes a housing 152, a
information reading member 153, a display 156, a name plate 158 and
a speaker 160. Information reading member 153 is illustratively a
key card slot 154 which interacts with magnetic stripe 136 on key
card 126. If the information carrying member 133 of key card 126 is
not magnetic stripe 136 then key card slot 154 is replaced with the
appropriate information reading member 153, input device or
detector 32 as discussed above in reference to FIG. 2. For instance
if key card 126 includes bar code region 138 then information
reading member 153 is a bar code reader such as an optical
scanner.
[0052] Navigation station 130, as shown in FIG. 6, operates in the
following way. Visitor 124 upon approaching a navigation station
130 passes key card 126 through key card slot 154. Navigation
station 130 reads the specific destination code stored on magnetic
strip 136 of key card 126. Based upon the specific destination
code, navigation station 130 provides visitor 124 with appropriate
destination instructions. The appropriate destination instructions
are provided either visually on display 156 or audibly through
annunciator 160 or a combination of both. The instructions may also
be printed.
[0053] The steps performed by navigation station 130 are shown in
FIG. 7. Navigation station 130 acquires the information contained
on information carrying member 133 of key card 126, as represented
by block 170. Station 130 then determines the appropriate
destination instruction 155 to give to visitor 124, as represented
by block 172. Navigation station 130 then displays the appropriate
destination instruction 155 as represented by block 174.
Additionally, navigation station 130, in one embodiment, audibly
emits the appropriate destination instruction 155, as represented
by block 176. After a pre-set time, navigation station 130 erases
display 156, resets and waits for the next key card 126 to be
passed through slot 154. Illustratively, the level of detail
included in appropriate destination instruction 155 by navigation
station 130 varies depending on the proximity of visitor 124 to his
specific destination. For example, more detailed instructions are
given the closer visitor 124 is to his specific destination. An
example detailed instruction is, "Room 2571 is down the hallway to
the left and is the fifth door on the right-hand side of the
hallway." A more general instruction is given by navigation station
130 when visitor 124 is further from his specific destination, such
as, "Take the hallway to the right, go the elevators on the left
hand side and proceed to third floor."
[0054] In one embodiment, navigation station 130 provides visitor
124 with all the instructions required to navigate from navigation
station 130 to the specific destination of visitor 124. As such,
visitor 124 needs only to stop at a future navigation station 130
if he forgets the last set of appropriate destination
instructions.
[0055] Typically, if appropriate destination instruction 155 does
not take visitor 124 to his specific destination, the instruction
does take visitor 124 to the next navigation station 130. Referring
to FIG. 3, in an illustrated embodiment, visitor 124 leaves core
station 128 and approaches navigation station 130a at the
intersection of hallway 106 and hallway 108. If the visitor
destination is emergency care unit 120, navigation station 130a
provides visitor 124 with the following appropriate destination
instruction 155, "Turn to the left and proceed to the navigation
station located at the T in the hallway." Alternatively, the
appropriate destination instruction 155 could include the name of
the next navigation station in the instruction. For example, the
appropriate destination instruction 155 might be, "Turn to the left
and proceed to the navigation station 130c".
[0056] Referring to FIG. 8, an embodiment of the appropriate
destination instruction logic 200 used by the processor 30 within
navigation station 130 is shown. Referring to FIGS. 3 and 8,
visitor 124 proceeds down hallway 106 with key card 126 to
navigation station 130a. Upon approaching navigation station 130a,
visitor 124 passes key card 126 through key card slot 154a.
Appropriate destination instruction logic 200, based on the
location of navigation station 130, provides a manageable method of
determining the appropriate destination instruction 155 to display.
The logic 200 provided in FIG. 8 is tailored to the location of
navigation station 130a within facility 102 in FIG. 3 and with the
assumption that the destination code stored in information carrying
member 133 corresponds to a patient room number. As such, FIG. 8,
is only an example of logic 200.
[0057] The first step of logic 200, as represented by block 202, is
to determine whether the room number programmed on key card 126 is
greater than 6000. If the room number is greater than 6000 the
appropriate destination instruction 155 displayed by navigation
station 130a is, "Take the corridor to the right to the bank of
elevators on the right and proceed to the second floor." If the
room number is not greater than 6000, logic 200 determines if the
room number is less than or equal to 3001, as represented by block
206. If the room number is less than 3001, then the appropriate
destination instruction 155, as represented by block 208, displayed
by navigation station 130a is, "Take the corridor to the right and
proceed to navigation station 130b." If the room number is greater
than or equal to 3001, then the appropriate destination instruction
155 displayed by navigation station 130A, as represented by block
210, is, "Take the corridor to the left and proceed to navigation
station 130c". Assuming visitor 124 is proceeding to patient room
4002, the logic 200 would display the instructions provided in
block 210 because room number 4002 is less than 6000 and greater
than 3001.
[0058] Additional features are included in other embodiments of
ambulatory navigation system 100. For example, as discussed before,
if the facility 102 has a single point of entrance, such as main
entrance 104, navigation station 130 may include a button 159 or
other member for activating navigation station 130 such that
navigation station 130 provides appropriate destination
instructions 155 on how to return to main entrance 104.
Additionally, in one embodiment, navigation station 130 and core
station 128 provide a call system and each includes a speaker 160,
a microphone, and a call button. As such, navigation stations 130
and core station 128 would operate as a call system to allow
visitors 124 to call core station 128 to ask facility personnel for
additional instructions. Additionally, in one embodiment,
navigation station 130 and core station 128 are integrated into a
caregiver locating and tracking system, such that the last known
location of visitor 124 is ascertainable in case of emergency or
such that traffic patterns of visitors are determined for
analysis.
[0059] Another embodiment of the present invention is illustrated
in FIG. 9. In the FIG. 9 embodiment, the information carrying
member 230 provides identification information such as an
identification number or other unique identification signal,
pattern or the like corresponding to the person seeking directions.
The information carrying member 230 is illustratively a magnetic
card, a bar-coded card, a RFID coil, an IR or RF emitting badge, a
fingerprint, a retina, or the like. The navigation station 232 in
the FIG. 9 embodiment illustratively includes an identification
device 234, a processor 236 coupled to a memory 237, and a
communication member 238. Illustratively, the identification device
234 corresponds to the particular type of information carrying
member 230 used with the navigation system 220. For instance,
identification device 234 is a magnetic card reader, a bar code
reader, a RF source and receiver, an IR or RF receiver, the
fingerprint reader, a retina scanner, or the like.
[0060] The identification device 234 detects the identification
information from information carrying member 230 and supplies the
information to processor 236. Processor 236 is coupled to a
database 240 by a wired or wireless communication network 242.
Illustratively, database 240 includes destination information
corresponding to the identification information detected by
identification device 234.
[0061] In operation, when a person enters a facility an information
carrying member 230 is provided to the person which provides unique
identification information for the person as discussed above.
Additional information related to the person is obtained and
entered into the database by an operator using an input device 244
such as a keyboard, mouse, touch screen display, voice recognition
device, or other type of input device. The operator also inputs
information in the database 240 related to the selected destination
of the person. Database 240 may also include navigation
instructions from different navigation stations to selected
destinations. The operator may also input the name of the person or
certain conditions such as handicaps of the person into the
database 240. The identification information on the information
carrying member 230 is correlated to the information input in the
database 240 related to the particular person.
[0062] Once the identification information is detected by
identification device 234 at a navigation station 232, processor
236 accesses database 240 to determine the selected destination
corresponding to the specific identification information detected
from the information carrying member 230 of the particular person.
Once the destination information is obtained from database 240,
processor 236 can obtain navigation instructions from database 240
or can use navigation instructions stored in memory 237 of
navigation station 232. Navigation instructions from the navigation
station 232 to the selected destination are then provided to the
person using communication member 238. The navigation instructions
can be personalized using the person's name identified from
database 240 so that the person knows that the instructions
provided by the communication member 238 are for him or her. In
addition, instructions can be customized based on additional
conditions of the person stored in database 240 such as handicaps
of the person. For instance, references to color can be omitted if
the person is color blind. If the person is mentally or otherwise
debilitated and at an unexpected location, the system 220 can alert
security to provide assistance.
[0063] The communication member 238 may be a speaker, display, or
printer as discussed above. In this embodiment, and the other
illustrated embodiments of the present invention, the communication
member need not be physically "coupled" to the processor. There may
be multiple communication members activated by the processor or
even subprocessors. For instance, a series of lights may
illustratively be installed on every walkway, hallway, step, door
of a facility, seat of a sports stadium or the like. When a person
enters with the information carrying member, the lights are lit in
a way to guide him to the appropriate location, room, seat, or the
like. Alternatively, the lights on the correct door or seat may
flash to provide an indication to the person. Also, the
communication member may be a portable device such as a PalmPilot
type device that the navigator carries with him. Therefore, it is
understood that the communication member is not be restricted to a
display, a speaker, or a printer. The communication member is
anything that communicates, whether it is permanently sited or
portable, whether it is sight, sound, or feel.
[0064] Use of database 240 provides flexibility for the navigation
system 220. For example, if a person must go to a second location,
the prior location listed in the database 240 is simply replaced
with the new location without the requirement for adjusting the
information carrying member 230.
[0065] In another embodiment of the present invention illustrated
in FIG. 10, the navigation system is integrated with a conventional
personnel and asset locating and tracking system such as the
COMposer.RTM. system or COMLINX.TM. system available from Hill-Rom
NetLinx located in Cary, N.C. See also U.S. pat. Nos. 5,561,412;
5,699,038; and 5,838,223 which are incorporated herein by
reference. In this embodiment, an attendant at a main entrance of a
facility or other desired location inputs information related to
the person into the locating and tracking system database 256 and
then provides the person with a badge 252 which transmits an
identification signal including identification information
identifying the person and/or a selected destination for the
person.
[0066] Illustratively, the badge 252 uses an infrared, radio
frequency, ultrasonic, or other type of transmitter which
periodically transmits signals from the badge. Receivers throughout
the facility and on the navigation stations detect the
identification information. Therefore, the locating and tracking
system tracks movement of the person through the facility and the
navigation stations provide directions to the person. An indicator
signal may be sent to a receiver on the badge if the patient does
not follow directions and is headed in the wrong direction away
from the selected destination.
[0067] Referring now to FIG. 10, the attendant at the main entrance
or other desired location facility provides the person with a
transmitter 250 such as an IR, RF, ultrasonic, or other type of
transmitter which periodically transmits a unique identification
data signal. Illustratively, the transmitter 250 is located on a
tag or badge 252 designed to be worn by the person entering the
facility. The attendant uses an input device 254 such as a master
station of a locating and tracking system to input information
related to the person, the selected destination, as well as any
other desired information regarding the person such as conditions,
handicaps, or the like into a database 256. Information in the
database 256 is correlated to the identification information
transmitted by transmitter 250.
[0068] In operation, when the person approaches a navigation
station 258, a receiver 260 of navigation station 258 detects the
identification signal from transmitter 250 in a conventional
manner. Receiver 260 is coupled to a processor 262 of navigation
station 258. Processor 262 accesses the database 256 using a wired
or wireless communication network 264. Based on the identification
information obtained from the signal, processor 262 obtains
corresponding destination information as well as information
related to the person such as name, handicaps, or the like from the
database 256. Processor 262 then obtains navigation instructions
based on the identified destination either from memory 266 of
navigation station 258 or from navigation instructions stored in
database 256. Processor 262 then communicates the instructions to
the person using communication member 268.
[0069] Processor 262 also updates the database 256 with the actual
location of the person in the facility. Conventional locating and
tracking system receivers 269 located throughout the facility also
detect the identification signal from transmitter 250. Receivers
269 are coupled to input device 254 to update actual location
information related to the person stored in database 256.
Therefore, the locating and tracking system tracks the actual
location of the person in the facility.
[0070] As discussed above with referenced FIG. 9, use of the
database 256 provides increased flexibility for the system. If the
person desires to go to a second location, the location information
can be updated in database 256 without changing the identification
signal from transmitter 250. The attendant or operator can also
enter a plurality of destinations for the person in database 256.
For instance, if a person desires to visit a specific room in a
hospital, that room can be entered as the first selected
destination. The second selected destination may be, for instance,
the cafeteria, the main entrance of the facility or other location.
As a patient moves from the main entrance toward the desired room,
directions are given at each navigation station 258 toward the
room. Once the locating and tracking system detects that a person
has reached the first selected destination, subsequent movement of
the patient will cause directions to be given to the second
selected destination. In another embodiment, as discussed above,
the attendant may program the transmitter with a unique
identification signal corresponding to the selected
destination.
[0071] In yet another embodiment of the present invention, the
navigation station 258 includes a transmitter 270 and the badge 252
includes a receiver 272. Processor 262 provides a wireless signal
273 from transmitter 270 to receiver 272. Receiver 272 is coupled
to display 274 on badge 252. Display 274 may be a indicator light,
LCD display, or other type of display screen. In addition, a
speaker 276 may be provided on badge 252. Therefore, the navigation
instructions or other information may be transmitted directly to
the display 274 or speaker 276 of badge 252.
[0072] The locating and tracking system tracks movement of the
patient through the facility and the navigation stations 258
provide directions to the person. The indicator signal 273 can be
provided from transmitter 270 to badge 252 if the locating and
tracking system determines that a person has not followed the
directions given to the person and is located at an unexpected
location. A signal or instructions can also be provided to the
person using a transmitter located at the master station or using
conventional paging or messaging techniques.
[0073] Although the invention has been described in detail with
reference to certain illustrated embodiments, variations and
modifications exist within the scope and spirit of the present
invention as defined in the following claims.
