`
`ABSTRACT
`
`Aportable terminal With the function of Walking navigation.
`The portable terminal displays information on its narroW
`screen so as to make it easy for the user (Walker) to
`understand and realiZe an interface that enables the user to
`understand inputs of retrieving conditions intuitively,
`thereby saving the input labor.
`
`Assume noW that a user (Walker) 10 is lost While Walking
`toWards a destination 11. In such a case, the present inven
`tion enables necessary information to be compressed, for
`example, so as to display both direction and distance to the
`destination from a present place With an orientation and a
`length of an arroW on a small screen and further so as to
`match the orientation of the arroW With the direction of the
`destination in the actual space. If the user (Walker) 10
`speci?es a compressed information item 12, 13, or 14 for
`inquiry, the present invention controls so that the arroW
`alWays points the direction of the destination corresponding
`to each of those compressed information items 12, 13, and
`14. The condition of retrieval can also be set by turning, for
`example, the tip of the portable terminal directly in the
`desired direction 12, 13, or 14.

`PORTABLE TERMINAL WITH THE
`FUNCTION OF WALKING NAVIGATION
`
`This is a continuation application of US. Ser. No.
`09/613,634, ?led Jul. 11, 2000, now US. 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 speci?ed
`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
`
`10

`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
`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.

`
`

`

`US 6,580,999 B2
`

`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” .

`the partner is noW.
`. used to knoW Where

`4) “Present Place Guidance Service” .
`the Walker (user) is noW When he/she is lost.
`To supply such services, the system is con?gured 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 con?guration 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
`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
`in conjunction With accompanying draWings.

`
`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 direction 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 How 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 ?rst, 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 ?oW
`When the Walker 10 selects Run in step 105. At ?rst, 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 ?rst, hoW information compression is
`controlled for this service Will be described With reference to
`the processing ?oW shoWn in FIG. 2. To begin the use of this
`service, at ?rst 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 ?rst 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
`neXt corner and the compressed information item 24 denotes
`a near distance to the neXt corner. In the case of the
`compressed information items 25 and 26, a full route from
`the starting point to the destination is represented simply by
`
`ZTE Exhibit 1012 - 14
`
`

`

`US 6,580,999 B2
`

`a bent line. The present place on the full route is always
`represented by a black circle on the bent line. Compressed
`information items 25 and 26 denote inquiries issued on
`middle points on the same route. BetWeen 21 and 26, the
`map is displayed With a direction of movement from the
`present place at the up-side.
`Compressed information items 21 and 22 can be supplied
`if the location information of both present place and desti
`nation is knoWn. In step 109, therefore, it is only needed to
`retrieve the location information of the destination simply
`from the name of the destination, etc. In this case, because
`the location information of the destination is not changed in
`the same route, retrieved information is stored once and the
`next and subsequent processings are omitted. In the next step
`110, both direction and distance to the destination from the
`present place are found from the location information of
`both present place and destination, then just represented by
`an arroW. On the other hand, to supply the compressed
`information items 23 and 24, the route information around
`the present place, selected from the route information
`betWeen the present place and the destination is required. In
`step 109, therefore, the system retrieves information of the
`route betWeen the present place and the destination by
`means of route retrieving and separates information of the
`route around the present place from this route information
`and supplies the information. In addition, to supply such
`compressed information items as 25 and 26, the system
`requires information of the route betWeen the starting point
`and the destination. In step 109, therefore, the system
`retrieves information of the route betWeen the starting point
`and the destination by means of route retrieving. In this case,
`because information of the route betWeen the starting point
`and the destination remains the same as long as the same
`route is taken, retrieved information is stored. In the next
`step 110, the system supplies the information of the route
`betWeen the starting point and the destination and the
`location information of the present place that are related to
`each other relatively.
`FIG. 4 shoWs hoW retrieving is controlled for the “Neigh
`borhood Guidance Service” With use of the portable terminal
`of the present invention With the function of Walking navi
`gation. This service is used When the Walker does not decide
`his/her destination yet and Wants to obtain information about
`movies, entertainment and business events, restaurants, etc.
`Hereafter, hoW information of the service is compressed and
`controlled Will be described With reference to the processing
`?oW shoWn in FIG. 2. At ?rst, the Walker is requested to
`select the “Neighborhood Guidance Service” from the ser
`vice menus, then selects a category for retrieving in step 103.
`In the example shoWn in FIG. 4, the Walker has selected a
`store as a category for retrieving. Usually, Walkers Who use
`this service do not search places around the present place
`conventionally, but they often Want to search speci?c
`information, for example, “What kinds of stores are there
`around the southern exit” and “What kinds of stores are there
`along this street”. HoWever, it is dif?cult to set such com
`plicated retrieving conditions by selecting an ordinary menu
`and a text input. To solve such a problem, therefore, the
`portable terminal of the present invention With the function
`of Walking navigation has enabled a destination to be
`speci?ed only by turning the tip of the portable terminal in
`the direction directly. In step 107, the system detects the
`orientation of the tip of the portable terminal and the
`orientation is set as a retrieving condition in step 108. Upon
`an inquiry speci?ed 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
