  In this way, if the travel information providing server system is used, the user can select or create his / her favorite travel plan using his / her PC (Personal Computer), etc., and this can be transferred to a portable terminal and used at the travel destination. . In addition, if the car navigation technology is used, the positional relationship between the destination and oneself can be known, and guidance can be facilitated.

  By the way, the route search developed by car navigation or the like uses a predetermined algorithm to go from the current position to the destination, for example, to find the shortest route. On the other hand, the travel plan has meal time, entertainment time, etc., and it does not always go to the destination in the shortest time, and there is a return or stagnation. Therefore, the car navigation guidance technology cannot be used as it is for a travel guide.

  In addition, since the processing capacity and storage capacity of mobile terminals are much slower and lower capacity than desktop terminals, there is a limit to incorporating a sufficient route search function, using a network such as the Internet. Even when communication such as route search is performed, a large amount of data takes time, and there is a limit to holding it.

  As described above, it is difficult for the conventional technology related to the travel information service system to provide a detailed service associated with a travel guide such as a travel route guide preferred by the user.

  The objective of this invention is providing the user portable terminal of the electronic travel guide which makes it possible to perform a user's favorite travel route guidance.

An electronic travel guide user portable terminal according to the present invention executes a travel guide application using a memory card that stores electronic travel guide data in cooperation with a user fixed terminal connected to an electronic travel guide server via a network.

And the electronic travel guide user portable terminal cooperate. That is, the user portable terminal uses a memory card in which necessary electronic travel guide data is transferred from the user fixed terminal. This memory card stores a route display according to a time series on a map of a travel destination area set by the user. Then, the user portable terminal reads this, receives information from the communication satellite, detects the current position, superimposes the detected current position and the route display according to the time series on the map, The route from the position to the destination is displayed on the screen.

  Therefore, the user uses the user fixed terminal in advance to set a favorite travel route on the map. The preferred travel route does not necessarily have to connect the destinations in the shortest time, and may return or stagnate in consideration of the available time zone of each destination. The favorite travel route set by the user in this way is transferred to the memory card as route display data according to time series, and is displayed on the user portable terminal together with the current position. The user can reproduce a favorite travel route set by the user at the travel destination, and can receive a preferred travel route guide according to the reproduced travel route.

  Furthermore, since the electronic travel guide update data is acquired from the electronic travel guide server via the network, the latest travel information, for example, the service contents of the destination can be acquired, and the electronic travel guide data can be acquired from the network one by one. There is no need to download the entire travel guide data. In other words, most of the electronic travel guide data is stored in the memory card, so that the information acquired from the network can be limited to a very small amount of update data. Therefore, the necessity of network communication can be minimized, and the object can be achieved in a short time even when communicating.

  Further, since the dangerous area in the travel destination area is displayed on the map, the user can receive the electronic travel guide with peace of mind even in an unknown land.

  Further, since the proximity signal is output when the distance on the map between the current position and the destination approaches a threshold value or less, the user can be notified that the destination has been approached.

  Since the destination information is displayed on the screen, the user can receive the destination information necessary for the user along with the route guidance.

  In addition, since the destination information is acquired from the destination via the network, the user can receive timely information when approaching the destination.

  As described above, according to the user portable terminal of the electronic travel guide according to the present invention, it is possible to provide a user's favorite travel route guidance.

Current route display module 128 that displays a route from the position to the destination, a dangerous area display module 130 that displays a dangerous region in the travel destination area, a proximity signal output module 132 that outputs a proximity signal when approaching the destination, A destination information display module 134 for displaying the previous information on the screen is included.

  These functions can be realized by software. Specifically, the functions can be realized by executing a PDA program including a corresponding electronic travel guide program. Moreover, you may comprise so that a part of each function may be implement | achieved by hardware.

  The overall procedure of the electronic travel guide system 10 having the above configuration will be described with reference to FIGS. FIG. 6 shows a procedure mainly for starting up an electronic travel guide application in the first half, and FIG. 8 shows a procedure for executing various functions of the electronic travel guide.

  FIG. 6 shows the exchange of procedures among the electronic travel guide server 12, the user fixed terminal 14, the memory card 30, and the user portable terminal 20. A user who wants to receive the electronic travel guide service applies to a provider that provides the electronic travel guide service. In FIG. 6, this application is shown as a registration application (S 70) from the user fixed terminal 14 to the electronic travel guide server 12. The electronic travel guide server 12 accepts the application, confirms payment of the registration fee, for example, and registers it in the customer master 32 (S72).

  Then, the user obtains the user portable terminal 20. When the user wants to obtain desired electronic travel guide data, the user requests the electronic travel guide server to provide the information (S74). In response to the request, the electronic travel guide server 12 first checks whether or not there is a registration (S76). If not, the request is rejected, and if it is determined that there is a registration, the requested information, that is, the electronic travel guide data is transmitted (S78), and the user fixed terminal 14 acquires this information (S80).

  The user processes the received electronic travel guide data according to his / her travel plan. At that time, considering that it is displayed on the user's own mobile terminal 20, it is processed so as to be convenient at the travel destination. The main thing is to set the destination scheduling as a route display according to the time series on the map. That is, on each day of the travel schedule, destinations are determined, their convenient times are examined, routes around them are set, and the route order is set on the map. For example, the user's favorite route display is created in consideration of the restaurant business hours, the theater program time zone, the performance time zone in the park, etc., and this is stored as the time series route display setting (S82). (S84). Note that a map provided by the electronic travel guide server 12 is used as a map for route display. This is because the map provided by the electronic travel guide server 12 is a standard map standardized so as to be compatible with the position information obtained by the GPS module 108.

  FIG. 7 is a diagram for explaining data set as a time-series route display, specifically, a display on the screen of the user fixed terminal 14. The time-series route display screen 50 includes a daily time table 52 for a certain travel date, each destination 56 represented by a circle and appropriately marked on a standard map 54 displayed on the screen, and a time. A time series path 58 is shown in which each destination 56 is connected by a user's favorite path along the time series of Table 52. As can be seen from FIG. 7, the user's favorite time-series path 58 has a return and includes a residence time in a park or the like.

  Further, the data processed in the user fixed terminal 14 includes not only time-series route display data but also destination partner store information and the like. For example, travel information related to each destination 56 connected by a time series route is acquired from the electronic travel guide server 12 and is associated with each destination 56. Such data as a whole becomes electronic travel guide data processed for the user portable terminal 20 in the user fixed terminal 14 and is stored in the storage device of the user fixed terminal 14.

  Returning to FIG. 6 again, the stored electronic travel guide data is moved to the memory card 30 when the user approaches the travel (S86), whereby specific electronic travel guide data 150 is stored in the memory card 30 (S88). ).

  When the user wants to receive the electronic travel guide service, the electronic travel guide application is started up (S90). The electronic travel guide application is stored in the memory 110 in advance. Then, the memory card 30 is inserted into a card insertion slot (not shown) of the user portable terminal 20 (S92). A memory card I / F 114 is provided at the card insertion slot, and the electronic travel guide application 150 can be executed by reading the electronic travel guide data 150 from the memory card 30.

  On the other hand, the electronic travel guide server 12 continuously updates the electronic travel guide data 150, and transmits the update information via the network 16 (S94). The user fixed terminal 14 receives this (S95). Also, the user portable terminal 20 receives the update information via the communication control unit 102 by the function of the update acquisition unit 138 of the CPU 100 (S96). In this case, the update acquisition unit 138 may have a function of selectively receiving only update data necessary for the user portable terminal 20. For example, only update data of specific electronic travel guide data 150 stored in the currently inserted memory card 30 can be received. Accordingly, the user portable terminal 20 is less required to have an extra storage capacity, and can communicate with the electronic travel guide server 12 via the network 16 in a short time. The received update information is used for data update (S98) of the memory card 30. For example, the partner store information of the destination is updated to the latest. In this way, the user portable terminal 20 can always use the latest electronic travel guide data 150.

  Then, an electronic travel guide application is executed using the latest electronic travel guide data 150 by the function of the electronic travel guide display unit 124 of the CPU 100 (S100), and an electronic travel guide screen is displayed on the color display 22. The The color display 22 includes the on-screen input unit 104 and the output unit 106 as described above, and the user can operate the electronic travel guide application interactively with the screen by pen input or manual input.

  FIG. 8 is a diagram showing a specific procedure of the electronic travel guide. The electronic travel guide is advanced interactively by the user using the input / output function of the color display 22 around the time-series route display stored in the memory card 30. Initially, a display that allows an overview of the entire schedule as described with reference to FIG. 7 is performed. Then, map display is performed on the color display 22 by the function of the map display module 126 in the CPU 100 of the user portable terminal 20 (S102). In this map display, as described above, a user-preferred time series route set in advance by the user fixed terminal 14 is displayed on the standard map. Then, the function of the current route display module 128 receives information from the communication satellite via the GPS module 108 to detect the current position of the user portable terminal, and superimposes the detected current position on the standard map, The current route is displayed (S104).

  FIG. 9 is a diagram showing a state of the electronic travel guide on the color display 22. FIG. 9A shows the screen of the color display 22, and the current position 202 of the user portable terminal 20 is displayed as a cross mark at the lower left on the standard map 54. A time series route 58 is displayed connecting the destinations 56. The orientation 201 on the screen of the standard map 54 is also displayed, and the current position coordinates 203 indicated by longitude and latitude are displayed at the top of the screen. Further, here, the position of the affiliated store registered in the affiliated store master 40 is indicated by an “climbing” mark 204. This is not a destination, but is useful when you want to change during a trip.

  The standard map 54 is displayed by continuously tapping an arbitrary arrow 206 placed around the screen by manual input or pen input, or by tapping the hand mark button 208, and manually or pen input the screen in an arbitrary direction. By dragging, the center can be moved in the vertical and horizontal directions, that is, in any direction. Further, every time the rotation mark 210 is tapped, the screen can be rotated by 90 degrees. Further, the magnification of the standard map 54 can be changed by tapping the eyeglass mark 212.

  Further, when the “point” button is tapped, a destination registration file 214 shown in FIG. 9B appears, and up to three arbitrary positions designated on the map can be registered. This is useful when you want to change your destination while traveling. The position can be specified by tapping a desired position on the screen by manual input or pen input. When the “display” button is tapped, the display switching file 216 shown in FIG. 9C appears, and the position of the standard map 54 automatically moves so that the registered destination appears on the screen. In the example of FIG. 9A, the destination 1 is indicated by the “eye” mark as the destination 56 closest to the current position. At this time, a distance 222 from the current position to the nearest destination 1 is displayed at the top of the screen. The destination may be a facility such as a park or a partner store. In the case of affiliated stores, the “climbing” mark 204 and the “eye” mark overlap, but the distance to the destination and the direction can be easily understood.

  When the “Search” button is tapped, a registered place search file 224 shown in FIG. 9D appears, and a list of affiliated stores registered in advance in the affiliated store master 40 is displayed. Then, by tapping the “eyes” or “climbing” mark on the map by manual input or pen input, the destination or other affiliated stores display different from the others in the registered location search file 224, for example, FIG. As shown by 9 (d), it is displayed surrounded by a frame. Or, conversely, by sequentially scrolling through the list of registered affiliated stores in the registered place search file 224, finding a destination or a desired store, and tapping it on the registered place search file 224 manually or by pen input, It is also possible to automatically move the standard map 54 of the color display 22 so that the position of the previous or desired store appears on the screen.

  As described above, the destination or desired affiliated store can be specified among the registered affiliated stores on the standard map 54 and the registered location search file 224 of the color display 22. In the example of FIG. 9D, the destination is “XX restaurant”. Then, on the registered location search file 224, when the registered affiliated store specified, “XX restaurant” in the above example, is tapped by manual input or pen input, as shown in FIG. The affiliated store information 226 is displayed. This information corresponds to the content of the affiliated store information 42 of the affiliated store master 40 described in FIG. The affiliated store information 226 is provided with, for example, a “reservation screen” 228 button. When this button is tapped, a reservation screen is displayed, and a reservation or the like can be made on the screen.

  FIGS. 10 and 11 show examples of a reservation screen for making a reservation, and here, a case is shown in which “Dinner A” is reserved for three persons at “XX restaurant”. In the reservation menu screen 70 of FIG. 10, three types of menus are presented together with their prices, and a menu selection button 72 and a number selection button 74 are shown. The user can specify the menu and the number of menus based on this information. When selection and designation are completed, the order screen 80 of FIG. 11 appears, and a calculation form 82 and an order button 84 are shown. By pressing the order button 84, a reservation order is established. These reservations may be made by communication between the user portable terminal 20 and the electronic travel guide server 12, and depending on the contract for the electronic travel guide service, the user portable terminal 20 directly connects to the affiliated store and the network 16. You may go. 10 and 11 show the case where the partner store is a restaurant, it may be a merchandise store other than that, or may be an accommodation facility such as a hotel.

  Payment associated with the reservation can also be made through the user portable terminal 20. For example, a specific money settlement is performed on behalf of an electronic travel guide service provider managing the electronic travel guide server 12, and the partner is charged via the electronic travel guide server 12 from the partner store, and thereafter It is possible to adopt a mechanism in which the contractor charges the user based on the customer master 32. In this case, a means for authenticating that the holder of the user portable terminal 20 who has eaten or shopped at the partner store is a user registered in the customer master 32 of the electronic travel guide server 12 is required. Become.

  For authentication that the holder of the user portable terminal 20 is a registrant of the customer master 32, data 90 for personal authentication as shown in FIG. 12 can be displayed on the color display 22. The personal authentication data can include pre-registered image data including the face photograph of the person and fingerprint pattern data of the person. Also, terminal ID data that is difficult to forge can be displayed. In this case, for example, it is possible to take a method of storing the terminal ID in a special memory that is built in the user portable terminal 20 and is prohibited from accessing other than the display purpose. Apart from this, the terminal ID may be displayed on a part of the casing of the user portable terminal 20 by a display that is difficult to forge, such as a hologram technique.

  Returning to FIG. 8 again, other functions of the user portable terminal 20 relating to the electronic travel guide will be described. When the user is guided according to the time series path 58 on the standard map 54 and approaches the destination 56, a signal indicating that the user has approached the destination is output by the function of the proximity signal output module 132 of the CPU 100 (S106). Specifically, a proximity signal is output when the distance between the current position 202 and the nearest destination 56 on the standard map 54 approaches a threshold value or less. As the threshold value, for example, 50 m can be set as an actual distance. The setting may be performed by the user or may be set as a standard value in advance. The proximity signal may be output by flushing the mark of the destination 56 on the color display 22, or outputting “soon destination” by voice, or simply notifying by a buzzer sound or the like.

  Further, as described in FIG. 9, the information of the destination 56 is retrieved and acquired by the user and displayed on the screen.
