`Title of the Invention
`
`PORTABLE TERMINAL WTTH THE FUNCTTON OF WALKING NAVIGATION
`
`Background of the fnvention
`The present invention relates to a portabre terminal
`includj-ng a portable telephone and a personal Handyphon€
`System (PHS) (including a telephone provided only with
`character data communication functions) and a personal daca
`assistance (PDA) terminal provided with portable telephone
`or PHS data communication functions. More particurarry, the
`present invention relates to a portable terminal provided
`with the function of walki-ng navigation, which can supply
`l-ocatj-on-related inf ormation to the walking user.
`Conventi-onally, there have been many map information
`services for supplying maps and other map-related conterrts
`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 pri-nted out onto papers through facsimile
`machines. However, the use of pDA terminals arrd data
`communication functions of portable tele---*phones or PHS's
`that are easy to carry about wourd make it easier for the
`users to obtain desj-red maps on sightseeing and business
`trips more favorably through the above services.

`
`There are also many systems under development to be
`used for supplying the location inforrnation 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 loo large for a walker to carry around. In
`additlon, because the narrigation system premises that the
`systent is used while the object car is running on a road,
`it cannot be used as a warkerr 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,
`r-tr r-s possrble 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 corrventional map information services supply maps
`through the rnternet, which are optimized on the assumption
`that the maps can be displayed at a resolution equivalent
`to that of personal computers. consequentry, 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 retrj-eving method employed for
`the above described services requires an enormous amount of
`cost for the communications with the server, so 1t is not

`
`suitable for walking navj-gation systems. For example, arr
`the case of a method that narrows retrieving conditions by
`drsplayj-ng a map in some steps of scales from a wide range
`to a detailed range, the map in each step must be down-toaded
`from the server in each of the retrieving operations. If
`text is entered and/or menus are selected to narrow those
`!vu!!uvrrry --nditions, however, it will be possible to
`f ; ^^a
`reduce the data communication amount durino retrievins.
`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 al_so suppliedr so that the
`desired map cannot be supplied directly.
`In such a case,
`the desj.red map wj-Il have to be retrieved by scrolling,
`scaling up/down the map in display.
`In addition, the rnap
`must be down-loaded in each of the display operations, since
`the map data is not accumulated beforehand in the local
`m6mn r\7
`
`Furthermore, maps supplled by the above descri.bed
`services 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
`possibly be described over a plurality of pages. Even when
`the route j-s described only on one page, the displayed range
`is often too wide to obtain detailed i.nformation. rn order
`to obtain necessary information in such a case, therefore,
`
`flL,J
`
`i
`

`
`
`

`
`the user is requested to make such compricated operations
`as scrol-li-ng, scaling up/down the displayed ildp, thereby the
`cost of communications with the server comes to be enormous
`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 servi-ces will be limited in number.
`rn addition, those portabre devices must be connected to
`each other via cable, so that it would not be easv to use

`servrces for supplying such j-nformation contents as movies,
`entertainment and business events, restaurants, etc.
`avairable with use of only a portabre telephone and/or a pHS
`terminal. Because it is premised that the information
`contents are disprayed on the narrow screens of those
`portable telephones and pHS terminals, character
`information is often supplied as contents. 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. rn addition, the portable telephone and
`the PHS terminal are just provided with some button keys
`including dialing buttons used as input devices, so they
`wil-l not able to cope with inputs of compricated retrieving
`conditions.

`On the other hand, the conventional pDA terminal with
`GPS and handy GPS are systems that can be used as a single
`If they are just used to display maps stored
`unit.
`beforehand in their local memories, they will not be a proper
`method to supply i-nformation 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,
`entertainment and business events, restaurants, etc. Of
`course, if the PDA terminal is additionallv provj_ded with

`The above descri-bed services will not vet be easier for the
`users to understand.
`Under such circumstances, it is an object of the
`present invention to provide a portable termlnal- with the
`functi-on of walking nAvigation, which can supply location
`infornation easier for the user to understand duri_ng walking
`with use of a narrow screen of a portable telephone and/or
`PHS terminal. It is another obiect of the present invention

`navigation, which can save labor to enter the condition for
`retrj-eving location information, dS well as realize a
`user-friendly interface that enables the walker (user) to

`
`rn order to achieve the above objects, the portable
`terrninal of the present invention wlth the function of
`walking navigation is provided wlth data communicatlon,
`input, and display devices just rike those of ordinary
`portable telephones and pHs terminals, as well as a device
`for getting location information and a d.evice for getting
`direction information denoting the user, s present place.
`Hereunder, the location information and the direction
`i nfnrmrJ-i nn n
`rrr!v&r!rqLrvrr. 90tt€n by those devices will be referred to as
`terrninal informatj-on col-lectively.
`Provided with those devices, the portable terminal of
`the present invention can use acquired termi_na1 information
`eu !EL!rsvrlrg uurruJ-Lro.QS, so the user can omit the input of
`as ro1- ri arzi na nnnd.i f i ^-
`his,/her present p1ace. The user can also specify a desired
`direction only by, for exampre, turning the tip of the
`portable terminar directly in the directi_on 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 arourrd 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 conditj-ons and it is possible to realize
`a user-friendly interface that enabres the user Eo
`understand disptayed items intuitively.
`rn addition, the
`use of terminal information makes i I nossible to match a

`l-ocati-on informatlon 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 informati_on
`easily while the inforrnation is compressed.
`When using the portable terminal of the present
`ir:ventj-on with the function of walking navigatj-on, 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 qet there.
`2) "Neighborhood Guidance Service,,.., used for such
`information guidance as movies, entertainment and business
`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
`wal-ker (user) is now when he/she is l-ost.
`To supply such services, the system is configured with
`a portable terminal of the nrcsoni- i nrranljgn with the
`

`
`function of walki-ng navi-gation respecti-vely and a server
`that supplies necessary information on the
`rnternet/intranet.
`Just like the rrrternet services
`available through portable telephones or pHs terminals,
`each portable terminal, wi-reless network, a gateway server,
`the rnternet/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
`informati-on contents as mov.ies. Fntr!rf aingignt and business
`events, restaurants, etc. The spatial information database
`may also be dispersed on the rnternet/intranet.
`Each
`processing proqram compresses information to be supplled 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 onry 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 respectivery. portable
`terminal-s that are a little higher in processing capacicy
`may also be employed to control- the display according to the
`

`above descriloed terminal information. In addition, entire
`map data may be received on such a portable terminal as a
`retrievi-ng result so that the portable terminal controls all-
`the necessary processings from compression to display of the
`map data according to the obj ect terminal j-nforrrratlon. A
`further high performance portable terminal may be used so
`as to store map informat.ion beforehand in its l-ocal mernory
`and execute all the necessary processings from retrieving
`to compression and display of nap information. In this case,
`the application server retrieves only such information
`contents as movies, entertainment and business events,
`restaurants, etc. that should be supplied in real tirne.
`Furthermore, in the portable terminal of the present
`invention with the function of walking navigation, location
`information to get is represented by a latitude/rongitude
`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 informati-on. The
`portable terminal of the present invention may al-so be
`provided with any one of the above methods for rneasuring
`position or some possible methods combined for measuring
`position. Direction information to get is a directj-on
`and/or an angle Of elevation renr6qrrnl-ing th€
`leading
`direction of the portable terminal or the orj-errtation of
`display. For example/ a compass, a gyro, such a sensor

`
`a clinometer/ etc. are used to measure a direction and/or
`an angle of elevation. In this case, the axis of the compass
`is allgned to the normal of the display and the display is
`kept horj-zontal to the ground, thereby it is possibre 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 elevati-on just like when a compass

`Descrj-ption of the preferred Embodiments
`Hereunder, the preferred ernbodiment of the presenc
`invention will be described with reference to the
`accompanying drawi_ngs. Fig.1 shows how data display is
`control-led by the portable terminal of the present invention
`with the function of walking navigation. A walker (user)
`10 is warking towards a destination 11. The walker can
`lrryur!s urrc >y'stem of the direction of his /her destination
`and in which direction he/she should go each time he/she is
`lost. According to the present invention, the system/ upon
`such an inquiry, supplies information compressed so as to
`be displayed on a narrow screen of the object portable
`telephone and/or pHS terminal. For example, the system
`supplies the direction and distance to the destinatj-on from
`the present place with an orientation and a l-enqth of an
`arrow on the screen. rn the case of ordinary map systems,
`the top side of the map on the screen denotes the north.
`Because warkers are usually walking unconsciously with
`u.rfecEr-ons, cne orientation of the map must be adjusted to
`the direction of the actual space. usuarry, the walker can
`Know nt-s/her present place from the randmark information

`
`written on the map. However, it is actual_ly impossibl-e to
`display such detailed information on the narrow screen to
`be ernployed 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 controlled so as to be adjusted
`to the orientation of the arrow dispLaved 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, L3, or !4, the screen display is
`controlled so that the arrow alwavs points the directi-on of
`the destination.
`Next, a description will be made for a total flow of
`a wal-kj-ng navigation processing wheri the portable terminal
`of the present j-nvention with the function of walking
`navigation is used. fn step 103, an input by the walker 10
`is control-l-ed so that,the walker 10 enters data to select
`a menu and/or set retrieving conditions on the setup screen
`int-or:ni-irra].'with use of sur:h an innrrf clevice as a button
`key, a pefl, a microphone, etc. of the portable terminal. fn
`step 104, the watking navigation system, expecting that the
`walker 10 will repeat inquiries, holds the input state in
`step 103. In this processing, dt first,
`the system
`determj-nes in step 101 whether or not any state is held. If
`any state is held, the system reads the state in step 1_02.

`terminal- with use of a device in step 105. The location
`information of the portable terminal here is represented by
`a latitude/Iongitude or coordinates and an altitude. For

`set in steps 103 and 108. If the route guidance service is
`selected in step 103, the system retrieves lnformation 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 snrall screen. In step 111, the system then controls

`destination with use of an input device. The destinatj-on,
`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

`denotes a near distance to the next corner. fn the case of
`the cornpressed information iterns 25 and 26, a full route from
`the starting point to the desti-natiorr is represented simply
`by a bent line. The present place on the ful-l route is always
`represented by a black circle on the bent line. Compressed
`information items 25 and 26 denote inquiries issued on

`Fl_g.4 shows how retrieving is controlled for the
`"Neighborhood Guidance Service" with use of the portable
`terminal of the present invention with the functi-on of
`walking navigation. This service is used when the walker
`does not decide his /her destination yet and wants to obtaj_rr
`informatj-on about movies, entertaj-nment 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 j-s requested to select the "Neighborhood Guldance
`Service" from the service 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.
`usualry, watKers 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 aiong this street". However, it is
`difficult
`to set such complicated retrieving conditions by
`selecting an ordinary menu and a text input. To solve such
