`ABSTRACT
`
`A portable terminal has a function of walking navigation.
`The direction of a deslnation 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 scren. At
`first, the user gets the location information of the portable
`terminal, represented by a latitude/longitude or coordinates
`and an allitude, forexample. 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.

`
`BACKGROUND OF TIlE INVENTION
`The present invention relates
`to a portable
`terminal
`including a portable telephone and a Personal Ilandyphone
`System (P1TS) (including a telephone provided only with
`character data communication functions) and a personal data
`assistance (PDA) terminal proviled with portable telephone
`or PUS 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 informatin
`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.
`Ilowever, the use ofPDA 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 abolve servies.
`There are also many systems under development to be
`used for supplying the location information around
`the
`present place through the GPS (Global Positioning
`.,r's
`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 ohject 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 ofsuch 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 I1 IE 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
`if portable telephones and PU1S terminals,
`small-size screen
`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 f 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 It 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 destinatiom, the route might pos
`sibly be described over a plurality of pages. Even when the
`0 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
`15 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
`the services will be limited in number. In
`can receive
`2 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
`25 of only a portable telephone and/i a PIS terminal. Because
`it is premised tha 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
`3 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
`5 rettieving 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
`45 PDA terminal is additionally provided with data communi-
`functions of a portable telephone and/or PUSl
`cation
`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 understandk
`Under such circumstances, it is an object of the present
`invention it 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
`s5 a narrow screen of a portable telephone and/or PUS 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
`65 display devices just like those of ordinary portable tele-
`phones and PIS terminals, as well as a device for getting
`location information and a device for getting direction

`
`information denoting the user's present place.
`lereunder,
`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 "whal 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 andor 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.
`
`It 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 infonation on the Intemet/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 Intemet/intranet. Each
`processing program compresses information to be supplied
`to portable terminals and controls the
`lisplay 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 conligu ration 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
`5 proassings from compression to display of the map data
`according to the object terminal information. A irther 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
`I 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 ofihe present iaven-
`lion 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 PIIS, etc., as well as an infrared ray
`sensor is used to measure location information The portable
`20 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 ispossible to know the direction (east, west, south,
`or north) in which the vertical axis of the display is onented.
`The gyro, when it is set so as to keep pointing the norlh, 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-dlmensional gyro may also be used
`for the above described measurement.
`These and other objects, fuatures, and advantages of the
`present invention will become more apparent in view ol 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. I shows how data lisplay is controlled
`by the portable terminal of the present invention with the
`function of walking navigation. A walker (user) 10 is walk-
`mg towards a destination 11. The walker can inquire the
`system of the direction of his/her destination and in which
`direction heishe should go each time he/she is lot. Accord-
`ing to
`the present invention, the system, upon such an
`inquiry, supplies information compressed sw 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-
`lion 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 10)4, 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 stale 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 In 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 1(6. The location
`information of the portable terminal here is represented by
`latitude/longitude or coordinates and an altitude. For
`a
`example, the location information is measured with use of a
`Cellular antenna and such an infrared ray sensor as a GSP,
`PIS, 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.
`5 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
`10 109,
`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
`III. If the route guidance service is selected in step 103, the
`system retrieves information of,
`tor example, a route
`15 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 Ill,
`20 the system then controls display of the information, which is
`a result of compression in step 110 so as to covert the
`information according to the terminal information set in step
`III. The information is thus displayed more easily for the
`walker to understand. At this time, the result of retrieving
`5 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.
`30 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. Ibis 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 proces.sing 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
`Ihe set states in step 103 are
`input from a microphone.
`needed each time the walker makes an inquiry, so they are
`45 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 firsl point
`may be registered in the system as a starting point and a
`passing point may be registered in the system as a middle
`5o point.
`Just like in FIG. 1, FIG. 3 show
`the walker 10 walking
`towards a destination 11, If the system receives an inquiry in
`a state between (a) and (t), information compression is
`controlled so as to be represented as compressed information
`s5 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
`60 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
`65 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
`a bent line. Ire 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 roule. Between 21 and 26, the
`map is displayed with a direction of movement from the
`present place at the up-side.
