Description

  The present invention relates to a system for delivering point information with priorities to navigation terminals.

  In recent years, navigation terminals that can be connected to a wide area network represented by the Internet are becoming widespread due to the development of wireless networks. These terminals can acquire information from a server connected to the Internet via a wireless network.

  Conventional navigation terminals are premised on the use of a single terminal, and the services to be provided are incorporated in the terminal. However, the connection to a wide area network has become possible, and it has become possible to provide services using content placed on the network. This makes it possible to distribute additional information with real-time properties.

As a map information service using information on the network, there is a service that controls the information drawn on the map on the web browser by scoring information displayed according to user usage and community reputation (patent) Reference 1). By using this technology, it is possible to narrow down the information presented to the user according to the reputation of the world from the vast amount of information and present it according to the priority order. Also, as a method for controlling the information presented to the user, time A technique for changing additional information to be provided by parameterizing position and preference has been proposed (Patent Document 2). By using this technique, it is possible to display additional information that takes into account the status and preferences of individual users.

  A general navigation terminal is equipped with a function for changing the scale of a map, and the map scale can be changed by a user operation. That is, the user can acquire facility information of a distant place by lengthening the unit distance and detailed facility information of a neighbor by shortening the unit distance.

  However, in the prior art, since the priority of the point information is determined only by the user's preference and the evaluation from the community, it is impossible to reflect the user's intention to view the information corresponding to the scale by changing the scale.

  Therefore, even though the user is assumed to be interested in the vicinity of the current location by shortening the unit distance, it is assumed that the user is interested in distant information by presenting information away from the current location or by increasing the unit distance. Despite this, information that the user does not want, such as presenting information near the current location, may be displayed.

The additional information distribution server includes means for receiving a point information request with additional information from the portal server, and means for transmitting point information with additional information corresponding to the received point information request with additional information to the portal server. A distribution system is disclosed.

  Further, in the disclosed point information distribution system, the portal server includes means for obtaining an operation point based on operation information received from the navigation terminal, and means for recording the obtained operation point in the distribution category priority table. May be.

  Further, in the disclosed point information distribution system, the additional information distribution server includes means for transmitting a correction point indicating a priority set for each scale determined by the administrator of the additional information distribution server to the portal server. The portal server may include means for recording the correction point received from the additional information distribution server in the distribution category priority table.

  Further, in the disclosed point information distribution system, the portal server associates an identifier of the navigation terminal, a user entry flag indicating the presence / absence of an operation point of the user of the navigation terminal 101, and a distribution category priority table. If the user entry flag indicates that the user's distribution category is not registered, a means for sending a distribution category input request to the navigation terminal and a distribution category input by the user received from the navigation terminal are displayed. Means for recording the operating point based on the distribution category priority table may be provided.

  With the above configuration, the user can obtain point information with additional information that meets the needs. Further, since the business operator can know the current viewpoint of the user, more effective information distribution is possible.

  Next, a graphical user interface (GUI) related to this embodiment will be described.

  FIG. 8 shows an example of the GUI of the navigation terminal 101 according to the embodiment.

  FIG. 8 includes a map display area 801 for displaying a map, a unit distance display area 802 for displaying a unit distance, and an information display area 803 for displaying point information with additional information of a distribution category.

  When the user starts the navigation terminal 101, the navigation terminal 101 displays the additional information-added point information of the distribution category according to the priority calculated by the portal server 102 in the information display area 803 as shown in FIG. 8a. When the unit distance is changed by a user operation, a scale corresponding to the unit distance is selected, and the distribution category distributed to the information display area 803 is changed by the display priority calculation unit 313 of the portal server 102, and the display as shown in FIG. Point information with additional information to be changed. In this way, the navigation terminal 101 can provide the user with additional information-added point information according to the scale.

  Next, a communication sequence according to the present embodiment will be described.

  FIG. 9 is an example of a communication sequence that occurs when the navigation terminal 101 is activated. When the user starts the navigation terminal 101 (901), the user operation data transmission unit 221 includes the identifier of the navigation terminal 101 and the unit distance set when the navigation terminal 101 is started to the user operation data reception unit 312 of the portal server 102. A navigation terminal activation notification is transmitted (902). The priority correction data request transmission unit 316 that has received the navigation terminal activation notification through the user operation data reception unit 312 transfers the activation notification to the priority correction data request reception unit 408 of the additional information distribution server 104 (903). Further, the priority order calculation unit 315 of the portal server 102 reads the user entry list 500 in the user operation log database 314 and confirms the value of the distribution category input request flag 502 of the user (904).

  When the distribution category input request flag 502 is 1, the priority correction data request transmission unit 316 transmits to the reception handler 212 a distribution category presence notification that indicates that the user's distribution category has been registered (905). Further, priority order correction data is received from the point information 412 with additional information (906). In accordance with the user operation log and the priority order correction data, the priority order calculation unit 315 calls the distribution information category priority table 700 and calculates the priority order of the distribution categories (907).

  When the distribution category of the user is not registered, that is, when the distribution category input request flag 502 is 0, the priority order correction data request transmission unit 316 sends a distribution category input request to the reception handler 212 (908), and requests the user Prompt for the delivery category to be sent (909). When the user inputs a desired distribution category (910), the user operation data reception unit 312 receives the distribution category from the user operation data transmission unit 211 (911), and sets a predetermined initial value for the operation point of the distribution category. (912). The points of other categories are set to 0. Then, priority order correction data is received from the priority order correction data transmission unit 411 (913), and the priority order of the distribution category is calculated (907).

  The above processing is performed when the navigation terminal 101 is activated.

  FIG. 10 is an example of a sequence that occurs when the user performs some operation on the navigation terminal 101.

  The user performs some operation on the navigation terminal 101 (1001). This operation includes an operation of changing the unit distance. Operation information is determined and recorded by the user operation acquisition unit 211 (1002), and at least an identifier, operation content, current position coordinates, and operation information notification including scale information corresponding to the unit distance of the map on the navigation terminal 101 The message is transferred from the user operation data transmission unit 211 to the user operation data reception unit 312 (1003).

  Upon receiving the operation information notification message, the portal server 102 performs registration (1004) in the user operation log database 314, calculates the priority of the distribution category in the priority calculation unit 315 (1005), and follows the processing result. The additional information-added point information requesting unit 409 is requested for the distribution category-added information-added point information (1006). In response, the additional information-added point information transmitting unit 318 reads the additional information-added point information according to the priority (1007), and transmits the additional information-added point information to the additional information-added point information receiving unit 308 (1008). The additional information-added point information transmitting unit 318 sends the additional information-added point information to the additional information-added point information receiving unit 214 (1009) and displays it on the display output 220 (1010).

  Next, an internal processing flow of the navigation terminal 101, the portal server 102, and the additional information distribution server 103 according to the present embodiment will be described.

  FIG. 11 is an example of an internal processing flow when the user operates the navigation terminal 101.

  When the navigation terminal 101 is activated, the user operation data transmission unit 221 notifies the user operation data reception unit 312 of the activation, the navigation identifier for identifying the navigation terminal 101, and the unit distance of the navigation terminal 101 set at the time of activation. (1101). The message received from the portal server 102 that has received the activation notification is determined (1102). If it is a distribution category presence notification, the process proceeds to destination input (1106). If it is a distribution category input request (1103), the user is prompted to input a distribution category (1104), and the result is sent to the portal server 102 (1105). Thereafter, the process proceeds to destination input (1106). If both the distribution category presence notification and the distribution category input request cannot be received, it is determined that there is some error, and the priority order correction data request 316 transmits the activation notification again (1101). The above is the flow performed at startup.

  Next, a flow performed while the navigation terminal 101 is operating is shown. First, the user inputs a destination to the user operation acquisition unit 211 (1106). Subsequently, the route search processing unit 217 searches for a route toward the destination (1107), and the navigation application result display generation unit 218 displays the result (1108). Thereafter, the user is inquired of whether or not guidance is possible on the searched route (1109). If yes, guidance is started (1110). If not, the procedure returns to route search (1107). After starting the guidance, the user operation data transmission unit 221 sends current position coordinates (1111) and scale information (1112) corresponding to the current display unit distance to the portal server (1113). The point information receiving unit 214 with additional information receives the point information with additional information sent from the point information transmitting unit 318 with additional information (1114), and the display information generating unit 219 sends the point information with additional information to the navigation terminal. Display on 101 (1015). When the user wants to set the destination by looking at the point information with additional information, the user clicks the point information with additional information (1116).

  Here, the point information with additional information has a plurality of operation links such as “detailed information” and “set as destination”. For example, when the “detailed information” link is clicked, 5 points are added to the operation point. You can add points. If clicked, the operation selected by the click is performed, and the operation instruction selected by the user operation acquisition unit 211 is sent to the user operation data reception unit 312 (1117). Next, it is determined whether or not the scale has been changed (1118). If there is a change, the process returns to the scale information transmission (1112). Note that the point information with additional information update (1119) is different from the point information with additional information if there is more than one point information with additional information when the point information with additional information is not clicked after a certain period of time. Update to Next, arrival at the destination is determined (1120). If it has arrived, the user operation data transmission unit 221 sends a destination arrival notification (1121) to the user operation data reception unit 312. If it has not arrived, the process returns to the current position coordinate transmission process (1111). If the user performs a distribution category change operation (1124), the user operation data transmission unit 221 sends a distribution category change notification (1125) to the user operation data reception unit 312 and returns to the user entry list reading (1103). The above is the flow performed when the navigation terminal 101 operates.

  Next, a flow to be performed when the navigation terminal 101 ends is shown. After the user operation data transmission unit 221 transmits the destination arrival notification (1121), it is determined whether or not the navigation terminal 101 is turned off (1122). If the power is not turned off, the process returns to the destination input (1106). If the power is turned off, the user operation data transmission unit 221 transmits an end notification to the user operation data reception unit 312 (1123), and the flow ends.

  FIG. 12 is an example of a processing flow inside the portal server 102 when the navigation terminal 101 requests the portal server 102 to perform processing. It represents from the start to the end of a certain navigation terminal 101, and processes corresponding to the number of active navigation terminals 101 are performed in parallel.

  After the flow starts, the user operation data reception unit 312 receives the activation notification from the user operation data transmission unit 221 (1201), and transmits the activation notification to the priority correction data request reception unit 408 of the additional information distribution server 103 (1202). ). The user entry list 500 is read from the navigation identifier included in the activation notification to see if there is an entry for the navigation terminal 101 (1203), and the distribution category input request flag value is determined there (1204, 904).

  When the flag is 1, a distribution category presence notification indicating the presence of an operation point is sent to the user operation acquisition unit 211 (1205). Then, the value of the correction point 602 for correcting the priority order is received from the priority order correction data transmission unit 411 (1206).

  When the flag is 0, the user is requested to input the distribution category (1207), the user operation data receiving unit 312 receives the distribution category (1208, 912), and then the priority is received from the priority correction data transmitting unit 411. The value of the correction point 602 to be corrected is received (1206).

  Next, the priority calculation unit 315 performs priority correction using the correction points 702 and the operation points 703 stored in the distribution information category priority table 700 (1209, 907). That is, the received distribution category (1208) value is recorded at the correction point 702, the distribution category value is recorded at the operation point 703, and calculation (addition in this case) is performed to calculate a total 704 for each scale. Determine the initial value. Then, the user operation data reception unit 312 receives the user operation information notification message sent from the navigation terminal 101 (1210), the priority order correction data storage unit 310 calculates the value of the operation point 703, and the user operation log The storage unit 313 writes in the user operation log database 314 (1211, 1004). By this processing, the user operation point 703 is rewritten. Using the written data, the priority order calculation unit 315 recalculates (adds here) the operation point 703 and the correction point 702, and determines the priority order of the distribution category (1212, 1005). Based on the priority, the additional information-added point information request transmitting unit 317 requests the additional information-added point information request receiving unit 409 to distribute the additional information-added point information belonging to the higher distribution category (1213). Here, it is possible to reflect the intention of the distribution server more by taking the correction point 602 that defines the priority order to the point information request receiving unit 409 with additional information other than at the time of activation. The point information with additional information is acquired from the additional information database 410 (1214), and the point information transmitting unit 412 with additional information distributes the content (1215). Subsequently, it is determined whether a delivery category change notification has been received (1216). If received, the operation point 703 of the distribution category priority table 700 is initialized to zero. Then, a distribution category input request is transmitted to the navigation terminal 101 (1217). If it has not been received, it is determined whether an end notification has been received from the navigation terminal 101 (1218) .If it has not been received, the process returns to receiving a user operation information notification message (1210). Exit.

  FIG. 13 is an example of an internal processing flow when the portal server 102 requests the additional information distribution server 103 to perform processing.

  FIG. 13a is a flow when the additional information-added point information transmitting unit 412 receives the activation notification. When the priority correction data request receiving unit 408 receives the activation notification (1301), the priority correction data determined by the operator is read (1302), and the priority correction data is transmitted to the priority correction data receiving unit 309 ( 1303).

  FIG. 13B is a flow when the additional information-added spot information request receiving unit 409 receives the additional information-added spot information request. When the point information request with additional information is received (1304), at least one piece of point information with additional information is read in accordance with the distribution category priority calculated by the portal server 102 (1305, 1007), and the point information with additional information is read. Is transmitted to the point information receiving unit 306 with additional information (1306).

  According to the embodiment described above, it is possible to distribute to the navigation terminal 101 appropriate point information with additional information according to the scale.
