`ABSTRACT
`
`A portable terminal has a function of walking navigation.
`The direction of the 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
`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
`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
`

`
`3
`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
`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 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
`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. 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
`flow shown in FIG. 2. At first, 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 Specific
`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 difficult 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
`Specified 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 Specified by turning the tip of the portable
`terminal in the direction of the destination as shown w
