`ABSTRACT
`(57)
`A portable terminal has a function of walking navigation.
`The direction of a destination is displayed by an indicating
`arrow that always points in the direction of the destination.
`In the navigation processing, the user enterS data to Select a
`menu and/or Set retrieving conditions on the Setup Screen. At
`first, the user gets the location information of the portable
`terminal, represented by a latitude/longitude or coordinates
`and an altitude, for example. Then, the user gets the direction
`information of the portable terminal, which is the direction
`of the tip of the portable terminal as determined by a
`compass, a gyro, or a clinometer. The location information
`and the direction information are set as terminal information
`for the retrieving conditions. The System controls retrieving
`of the database and retrieves the information corresponding
`to the Selected menu, Such as route guidance.

`PORTABLE TERMINAL WITH THE
`FUNCTION OF WALKING NAVIGATION
`
`This is a continuation application of U.S. Ser. No.
`10/173,423, filed Jun. 18, 2002, now U.S. Pat. No. 6,580,
`999; which is a continuation application of U.S. Ser. No.
`09/613,634 filed Jul. 11, 2000, now U.S. Pat. No. 6,430,498.
`BACKGROUND OF THE INVENTION
`The present invention relates to a portable terminal
`including a portable telephone and a Personal Handyphone
`System (PHS) (including a telephone provided only with
`character data communication functions) and a personal data
`assistance (PDA) terminal provided with portable telephone
`or PHS data communication functions. More particularly,
`the present invention relates to a portable terminal provided
`with the function of walking navigation, which can Supply
`location-related information to the walking user.
`Conventionally, there have been many map information
`Services for Supplying maps and other map-related contents
`through the Internet and facsimile machines. In the case of
`those Services, it is premised that information is Supplied So
`as to be output onto Such wide monitor Screens of computers
`and printed out onto paperS through facsimile machines.
`However, the use of PDA terminals and data communication
`functions of portable telephones or PHS's that are easy to
`carry about would make it easier for the users to obtain
`desired maps on Sightseeing and busineSS trips more favor
`ably through the above Services.
`There are also many Systems under development to be
`used for Supplying the location information around the
`user's present place through the GPS (Global Positioning
`System). For example, a car navigation System to be
`mounted on a car is too large for a walker to carry around.
`In addition, because the navigation System premises that the
`System is used while the object car is running on a road, it
`cannot be used as a walker's navigation System as is. On the
`other hand, in the case of Such a location information System
`as a PDA with GPS and a handy GPS intended to walkers,
`it is possible to show the user's present place on a map Stored
`beforehand in its local memory or down-loaded from the
`above Services.
`
`SUMMARY OF THE INVENTION
`The conventional map information Services Supply maps
`through the Internet, which are optimized on the assumption
`that the maps can be displayed at a resolution equivalent to
`that of personal computers. Consequently, they have been
`confronted with a problem that the maps, when displayed on
`small-size screen of portable telephones and PHS terminals,
`are not displayed clearly.
`In addition, the map retrieving method employed for the
`above described Services requires an enormous amount of
`cost for the communications with the Server, So it is not
`Suitable for walking navigation Systems. For example, in the
`case of a method that narrows retrieving conditions by
`displaying a map in Some Steps of Scales from a wide range
`to a detailed range, the map in each Step must be down
`loaded from the Server in each of the retrieving operations.
`If text is entered and/or menus are Selected to narrow those
`retrieving conditions, however, it will be possible to reduce
`the data communication amount during retrieving. In spite
`of this, the method still has some problems that if a specified
`place name is recorded over a plurality of pages, maps on the
`adjacent pages are also Supplied, So that the desired map
`cannot be Supplied directly. In Such a case, the desired map

`will have to be retrieved by Scrolling, Scaling up/down the
`map in display. In addition, the map must be down-loaded in
`each of the display operations, Since the map data is not
`accumulated beforehand in the local memory.
`Furthermore, maps Supplied by the above described Ser
`vices are not always easy for Walkers to understand. For
`example, when a walker (user) wants to know a route from
`his/her present place to a destination, the route might pos
`sibly be described over a plurality of pages. Even when the
`route is described only on one page, the displayed range is
`often too wide to obtain detailed information. In order to
`obtain necessary information in Such a case, therefore, the
`user is requested to make Such complicated operations as
`Scrolling, Scaling up/down the displayed map, thereby the
`cost of communications with the Server comes to be enor
`mous as described above.
`Furthermore, if the object system requires a PDA terminal
`in addition to the portable telephone or the PHS, users who
`can receive the services will be limited in number. In
`addition, those portable devices must be connected to each
`other via cable, So that it would not be easy to use them
`during walking. On the other hand, there are also Services for
`Supplying Such information contents as movies, entertain
`ment and business events, restaurants, etc. available with use
`of only a portable telephone and/or a PHS terminal. Because
`it is premised that the information contents are displayed on
`the narrow screens of those portable telephones and PHS
`terminals, character information is often Supplied as con
`tents. However, when the user wants to know Such a Spatial
`position as a place and a route, those Services will be difficult
`to cope with the user's need. In addition, the portable
`telephone and the PHS terminal are just provided with some
`button keys including dialing buttons used as input devices,
`So they will not able to cope with inputs of complicated
`retrieving conditions.
`On the other hand, the conventional PDA terminal with
`GPS and handy GPS are systems that can be used as a single
`unit. If they are just used to display maps Stored beforehand
`in their local memories, they will not be a proper method to
`Supply information matching with the user's needs and
`easier to understand. Also in this case, they will not be able
`to Supply Such real time information as movies, entertain
`ment and busineSS events, restaurants, etc. Of course, if the
`PDA terminal is additionally provided with data communi
`cation functions of a portable telephone and/or PHS
`terminal, however, it will be possible to connect them to
`Internet map information Services only as a single unit. The
`above described services will not yet be easier for the users
`to understand.
`Under Such circumstances, it is an object of the present
`invention to provide a portable terminal with the function of
`walking navigation, which can Supply location information
`easier for the user to understand during walking with use of
`a narrow screen of a portable telephone and/or PHS termi
`nal. It is another object of the present invention to provide
`a portable terminal with the function of walking navigation,
`which can Save labor to enter the condition for retrieving
`location information, as well as realize a user-friendly
`interface that enables the walker (user) to understand inputs
`of retrieving conditions intuitively.
`In order to achieve the above objects, the portable termi
`nal of the present invention with the function of walking
`navigation is provided with data communication, input, and
`display devices just like those of ordinary portable tele
`phones and PHS terminals, as well as a device for getting
`location information and a device for getting direction
`
`

`

`Case 5:19-cv-00036-RWS Document 1-2 Filed 03/15/19 Page 14 of 18 PageID #: 80

`information denoting the user's present place. Hereunder,
`the location information and the direction information gotten
`by those devices will be referred to as terminal information
`collectively.
`Provided with those devices, the portable terminal of the
`present invention can use acquired terminal information as
`retrieving conditions, So the user can omit the input of
`his/her present place. The user can also specify a desired
`direction only by, for example, turning the tip of the portable
`terminal directly in the direction instead of entering Such
`direction information as “towards the Southern exit' or
`“along this street' when the user wants to know “what kinds
`of stores are there around the Southern exit of the station”
`and/or “what kinds of stores are there on this street'.
`Consequently, the user can Save labor to enter retrieving
`conditions and it is possible to realize a user-friendly inter
`face that enables the user to understand displayed items
`intuitively. In addition, the use of terminal information
`makes it possible to match a direction in an actual Space with
`the displayed direction on the Screen. For example, it is
`possible to compress information So as to display a direction
`of movement from the present place simply with an arrow.
`Consequently, location information can be displayed on a
`small-size display screen of a portable telephone and an PHS
`terminal So that the user can understand the displayed
`information easily while the information is compressed.
`When using the portable terminal of the present invention
`with the function of walking navigation, it is expected that
`the following Services are available.
`
`1) “Route Guidance Service'. . . used when the user has
`decided a destination, but does not know how to get there.
`2) "Neighborhood Guidance Service'. . . used for Such
`information guidance as movies, entertainment and busi
`neSS events, restaurants, etc. when the destination is not
`decided yet.
`3) “Meeting by Appointment Guidance Service'. .
`. used
`when meeting Someone by appointment So as to notify the
`partner of his/her present place and/or to confirm where
`the partner is now.
`4) “Present Place Guidance Service'... used to know where
`the walker (user) is now when he/she is lost.
`To Supply Such Services, the System is configured with a
`portable terminal of the present invention with the function
`of walking navigation respectively and a Server that Supplies
`necessary information on the Internet/intranet. Just like the
`Internet Services available through portable telephones or
`PHS terminals, each portable terminal, wireless network, a
`gateway Server, the Internet/intranet, and the application
`Server are Sequentially connected. The application Server is
`provided with a spatial information database, a database
`management System, as well as a control program. The
`Spatial information database Stores maps information and
`Such information contents as movies, entertainment and
`business events, restaurants, etc. The Spatial information
`database may also be dispersed on the Internet/intranet. Each
`processing program compresses information to be Supplied
`to portable terminals and controls the display on those
`terminals according to the terminal information. Concretely,
`the application Server executes most of processings for
`walking navigation and each portable terminal is provided
`only with the function for displaying Supplied information.
`The above configuration is assumed So that Such portable
`terminals as portable telephones and PHS terminals are low
`in processing capacity respectively. Portable terminals that
`are a little higher in processing capacity may also be
`
`4
`employed to control the display according to the above
`described terminal information. In addition, entire map data
`may be received on Such a portable terminal as a retrieving
`result So that the portable terminal controls all the necessary
`processings from compression to display of the map data
`according to the object terminal information. A further high
`performance portable terminal may be used So as to Store
`map information beforehand in its local memory and
`execute all the necessary processings from retrieving to
`compression and display of map information. In this case,
`the application Server retrieves only Such information con
`tents as movies, entertainment and business events,
`restaurants, etc. that should be Supplied in real time.
`Furthermore, in the portable terminal of the present inven
`tion with the function of walking navigation, location infor
`mation to get is represented by a latitude/longitude or
`coordinates and an altitude. For example, Such a wireleSS
`antenna as a GPS, a PHS, etc., as well as an infrared ray
`Sensor is used to measure location information. The portable
`terminal of the present invention may also be provided with
`any one of the above methods for measuring a position or
`Some possible methods combined for measuring a position.
`Direction information to get is a direction and/or an angle of
`elevation representing the leading direction of the portable
`terminal or the orientation of the display. For example, a
`compass, a gyro, Such a Sensor as a clinometer, etc. are used
`to measure a direction and/or an angle of elevation. In this
`case, the axis of the compass is aligned to the normal of the
`display and the display is kept horizontal to the ground,
`thereby it is possible to know the direction (east, west, South,
`or north) in which the vertical axis of the display is oriented.
`The gyro, when it is Set So as to keep pointing the north, can
`measure both direction and angle of elevation just like when
`a compass is used. In addition, if both compass and clinom
`eter are used, it is possible to get not only a direction, but
`also Such three-dimensional direction information as an
`angle of elevation to the ground. Instead of those compass
`and clinometer, a three-dimensional gyro may also be used
`for the above described measurement.
`These and other objects, features, and advantages of the
`present invention will become more apparent in View of the
`following detailed description of the preferred embodiments

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`Hereunder, the preferred embodiment of the present
`invention will be described with reference to the accompa
`nying drawings. FIG. 1 shows how data display is controlled
`by the portable terminal of the present invention with the
`function of walking navigation. A walker (user) 10 is walk
`ing towards a destination 11. The walker can inquire the
`system of the direction of his/her destination and in which
`direction he/she should go each time he/she is lost. Accord
`ing to the present invention, the System, upon Such an
`inquiry, Supplies information compressed So as to be dis
`played on a narrow Screen of the object portable telephone
`and/or PHS terminal. For example, the system supplies the
`direction and distance to the destination from the present
`place with an orientation and a length of an arrow on the
`Screen. In the case of ordinary map Systems, the top side of
`the map on the Screen denotes the north. Because walkers
`are usually walking unconsciously with directions, the ori
`entation of the map must be adjusted to the direction of the
`actual Space. Usually, the Walker can know his/her present
`place from the landmark information written on the map.
`However, it is actually impossible to display Such detailed
`information on the narrow Screen to be employed for the
`portable terminal of the present invention. In order to solve
`Such a problem, therefore, the present invention enables the
`direction of the destination in the actual Space to be con
`trolled so as to be adjusted to the orientation of the arrow
`displayed on the screen. If the walker 10 inquires the system
`of a direct-ion by turning his/her portable terminal as shown
`with the compressed information item 12, 13, or 14, the
`Screen display is controlled So that the arrow always points
`the direction of the destination.
`Next, a description will be made for a total flow of a
`walking navigation processing when the portable terminal of
`the present invention with the function of walking naviga
`tion is used. In step 103, an input by the walker 10 is
`controlled so that the walker 10 enters data to select a menu
`and/or Set retrieving conditions on the Setup Screen interac
`tively with use of Such an input device as a button key, a pen,
`a microphone, etc. of the portable terminal. In step 104, the
`walking navigation System, expecting that the walker 10 will
`repeat inquiries, holds the input State in Step 103. In this
`processing, at first, the System determines in Step 101
`whether or not any state is held. If any state is held, the
`system reads the state in step 102. If no state is held, the
`system controls the input in step 103. In step 105, the system
`waits for an input. In Step 105, three choices are prepared;
`Run to execute the processings in steps 106 to 111, Back to
`return to the setup screen in step 103, and Stop to exit the
`program.
`Next, a description will be made for a processing flow
`when the walker 10 selects Run in step 105. At first, the
`walker 10 gets the location information of the portable
`terminal with use of a device in step 106. The location
`information of the portable terminal here is represented by
`a latitude/longitude or coordinates and an altitude. For
`example, the location information is measured with use of a
`Cellular antenna and Such an infrared ray Sensor as a GSP,
`PHS, or the like. Then, the walker 10 gets the direction

`information of the portable terminal with use of a device in
`step 107. The direction information is the direction of the tip
`of the portable terminal or the orientation of the display
`Screen represented by a direction and an angle of elevation.
`For example, a compass, a gyro, and Such a Sensor as a
`clinometer are used to measure the direction information. In
`step 108, the walker 10 sets the location information gotten
`in step 106 and the direction information gotten in step 107
`as terminal information for retrieving conditions. In Step
`109, the system controls retrieving of the database and
`retrieves the information corresponding to the menu Selected
`in step 103 on the retrieving conditions set in steps 103 and
`108. If the route guidance service is selected in step 103, the
`System retrieves information of, for example, a route
`between the present place and the destination. In Step 110,
`the System controls compression of the information, which
`is a result of retrieving in step 109 So as to compress the
`information according to the terminal information Set in Step
`108 so that it is displayed on the small screen. In step 111,
`the System then controls display of the information, which is
`a result of compression in Step 110 So as to convert the
`information according to the terminal information Set in Step
`108. The information is thus displayed more easily for the
`walker to understand. At this time, the result of retrieving
`may be stored as needed. Finally, the System returns to Step
`105 So as to wait for another input.
`Next, a description will be made in detail for the portable
`terminal of the present invention with the function of
`walking navigation on the assumption of concrete Services.
`FIG. 3 shows how information compression is controlled for
`the “Route Guidance Service” with use of the portable
`terminal of the present invention with the function of
`walking navigation. This service is used when the walker 10,
`who has decided his/her destination, does not know the route
`to the destination. At first, how information compression is
`controlled for this service will be described with reference to
`the processing flow shown in FIG. 2. To begin the use of this
`Service, at first the walker is requested to Select “Route
`Guidance Service” from the service menus in step 3. Then,
`the walker must Set the destination with use of an input
`device. The destination, for example, can be set with a text
`input with use of button keys or a pen and/or with a voice
`input from a microphone. The set states in step 103 are
`needed each time the walker makes an inquiry, So they are
`held in the system in step 104. The present place is updated
`automatically with the location information gotten in Step
`106 each time the walker makes an inquiry. The first point
`may be registered in the System as a starting point and a
`passing point may be registered in the System as a middle
`point.
`Just like in FIG. 1, FIG. 3 shows the walker 10 walking
`towards a destination 11. If the System receives an inquiry in
`a state between (a) and (f), information compression is
`controlled So as to be represented as compressed information
`items 21 to 26 in the portable terminal of the present
`invention with the function of walking navigation. In the
`case of the compressed items 21 and 22, information is
`compressed So that both direction of the destination and
`distance from the present place are represented by an ori
`entation and a length of an arrow. The compressed infor
`mation item 21 denotes a far distance to the destination and
`the compressed information item 22 denotes a near distance
`to the destination respectively.
`In the case of the compressed information items 23 and
`24, the direction in which the walker 10 goes around the
`present place is represented by a bent line and an arrow. The
`compressed information item 23 denotes a far distance to the
`
`

`orientation is Set as a retrieving condition in Step 108. Upon
`an inquiry Specified by turning the tip of the portable
`terminal in the direction of the destination as shown with
`compressed information 31, 32, or 33, the portable terminal
`of the present invention with the function of walking navi
`gation Supplies, for example, a list of Stores existing in the
`Specified direction. The portable terminal can also be
`designed So as to display detailed information of each Store
`in the list if the walker selects the store.
`Next, a description will be made for an embodiment of the
`“Meeting by Appointment Guidance Service' with use of
`the portable terminal of the present invention with the
`function of walking navigation with reference to FIGS. 5, 6,
`and 7. This service is used when the user (walker), who is
`to meet Someone by appointment, notifies his/her present
`place to the partner and confirm the partner's present place.
`In FIG. 5, 10a and 10b denote walkers who will meet each
`other by appointment. Compressed information items 41 and
`42 denote flows of data Sending/receiving to confirm their
`present places. In this embodiment, data may be exchanged
`directly between portable terminals just like the message
`sending function of portable telephones and PHS terminals.
`Otherwise, data may be exchanged via an Internet Server just
`like the e-mail functions.
`At first, the processing flow of data Sending shown in FIG.
`6 will be described on the assumption that the walker 10a
`notifies his/her present place to the walker 10b. The pro
`cessings in steps 101 to 106 are identical to those shown in
`FIG. 2. When sending data, the walker 10a selects the data
`sending menu from the menus of this service in step 103 and
`sets the phone number of the walker 10b as the destination.
`In this case, if the walker 10a selects Run in step 105, the
`location information gotten in step 106 is sent to the walker
`10b in step 201.
`Next, the processing flow of data receiving shown in FIG.
`7 will be described on the assumption that the walker 10b
`confirms the partner's present place. In Step 202, if the
`walker 10b receives location information from the walker
`10a, the phone number of the walker 10a, who is a source
`of data Sending, as well as the received position information
`are stored as the partner's states in step 104. If the walker
`10b selects Run in step 105, the system executes the
`processings in StepS 106 to 111, then displays the partner's
`present place on the Screen of the portable terminal of the
`walker 10b in step 105. The series of processings in steps
`106 to 111 are the same as the processings for the “Route
`Guidance Service' in which the partner's present place is Set
`as a destination. The portable terminal shown in FIG. 5
`displays both direction and distance to the partner's present
`place (destination) from the user's present place (the present
`place). In this embodiment, the starting point (user's present
`place) of the arrow is represented by a black circle and the
`ending point (partner's present place) of the arrow is rep
`resented by a white circle instead of the arrow used for the
`“Route Guidance Service'. To display the partner's present
`place again after Stop is Selected to exit the processing in
`Step 105, the same processing as that in FIG. 2 is executed.
`FIG.8 shows how retrieving is controlled for the “Present
`Place Guidance Service” with use of the portable terminal of
`the present invention with the function of walking naviga
`tion. This service is used to confirm where the user (walker)
`is now when he/she is lost. There may be services realized
`by the conventional technique So as to Supply a map around
`the present place, but it would be difficult to display Such a
`map on Such a Small-size Screen
