  Returning to FIG. 2, when the history information storage unit 102d of the terminal device 100 determines that the storage condition is met in Step SA-9 (Step SA-9: Yes), the history information storage unit 102d proceeds to the process of the next Step SA-10. On the other hand, if the history information storage unit 102d of the terminal device 100 determines in step SA-9 that the storage condition is not met (step SA-9: No), the process returns to step SA-5.

  Then, the history information storage unit 102d of the terminal device 100 stores the facility information as history information in the history information file 106a based on the predetermined storage condition stored in the storage condition file 106b (step SA-10).

  As described above, in steps SA-7 to SA-10, the history information storage unit 102d of the terminal device 100 changes the map display screen in the map display area by the processing of the display map change unit 102c in step SA-6. At this time, the facility information corresponding to the facility icon included in the map display screen in the map display area is stored in the history information file 106a as history information. Thereafter, the process proceeds to step SA-11.

  Here, in addition to the “history information storage process (steps SA-4 to SA-10)” shown in FIG. 2, the “history information storage process (steps SB-1 to SB-15)” shown in FIG. You may go.

  Hereinafter, with reference to FIG. 3, an example of processing in the case where facility information related to a facility that has passed on the map display area screen due to a change operation is stored as history information will be described.

  In FIG. 3, the processes in steps SB-1 to SB-6 are the same as the processes in steps SA-4 to SA-9 in FIG.

  As illustrated in FIG. 3, when the history information storage unit 102d of the terminal device 100 determines in step SB-6 that the storage condition is met (step SB-6: Yes), the predetermined information stored in the storage condition file 106b. Based on the storage conditions, the facility information is stored in the storage unit 106 as the first history information (step SB-7). That is, when the map display screen in the map display area is changed by the processing of the display map changing unit 102c in step SB-3 (for example, from FIG. 4A to FIG. 4B), the history information storage unit 102d is changed. 4), the facility icons included in the map display screen in the map display area (for example, the star-shaped icons 1, 2 and 2 included in the map display screen of FIG. 4A). The facility information (for example, the facility information of POI-1, POI-2, POI-3, and POI-4 in FIG. 4A) is stored as the first history information. The data is stored in the unit 106 (for example, the memory in FIG. 4A). Thereafter, the process proceeds to step SB-8.

  Here, in FIG. 3, the processing of steps SB-8 to SB-12 is the same as the processing of steps SA-5 to SA-9 of FIG.

  When the history information storage unit 102d of the terminal device 100 determines that the storage condition is met in Step SB-12 (Step SB-12: Yes), the history information storage unit 102d is based on the predetermined storage condition stored in the storage condition file 106b. The facility information is stored in the storage unit 106 as second history information (step SB-13). That is, the history information storage unit 102d further changes the map display screen in the map display area by the processing of the display map change unit 102c in step SB-9 (for example, from FIG. 4B to FIG. 4 ( c), the facility icon included in the map display screen in the map display area (for example, the star-shaped icon 3 included in the map display screen of FIG. 4B). The storage unit 106 (for example, facility information of POI-3, POI-4, POI-5 in FIG. 4B) as the second history information (for example, the facility icons indicated by the facilities icons 4 and 5). In FIG. 4B, it is stored in a memory). Thereafter, the process proceeds to step SB-13.

  Then, the history information storage unit 102d of the terminal device 100 stores the first history information (for example, FIG. 4A) stored in the storage unit 106 (for example, the memory in FIG. 4) in steps SB-7 and SB-13. ), POI-1, POI-2, POI-3, POI-4) and second history information (for example, POI-3, POI-4, POI-5 in FIG. 4B) are compared. Then, it is determined whether or not there is a difference (step SB-14). Here, the history information storage unit 102d may compare the first history information and the second history information stored in the storage unit 106 at predetermined time intervals.

  If the history information storage unit 102d of the terminal device 100 determines that there is a difference in step SB-14 (step SB-14: Yes), the process proceeds to the next step SB-15. On the other hand, if the history information storage unit 102d of the terminal device 100 determines in step SB-14 that there is no facility information (step SB-14: No), the process returns to step SB-8.

  Then, the history information storage unit 102d of the terminal device 100 compares the first history information stored in the storage unit 106 with the second history information in step SB-14 and the difference facility information (for example, In FIG. 4B, facility icons of POI-1 and POI-2) that have left the map display area (for example, the facility icons indicated by the star-shaped icons 1 and 2 in FIG. 4B). ) And stores the determined facility information as history information in the history information file 106a (for example, history information storage means in FIG. 4B) (step SB-15).

  The history information storage process shown in the flowchart of FIG. 3 can be similarly applied when the map display screen of FIG. 4C is changed.

  For example, the history information storage unit 102d of the terminal device 100 may change the map display screen in the map display area by the processing of the display map change unit 102c (for example, from FIG. 4B to FIG. 4C). When changing to the map display screen, the facility icons included in the map display screen in the map display area (for example, star icons 3, 4, 5 included in the map display screen of FIG. 4B) (For example, the facility information of POI-3, POI-4, and POI-5 in FIG. 4B) as the first history information in the storage unit 106 (for example, FIG. 4). In (b), when the map display screen in the map display area is changed by the processing of the display map changing unit 102c (for example, the map display screen in FIG. 4C is changed). Map) Facility information (for example, FIG. 4C) corresponding to facility icons (for example, the facility icon indicated by the star-shaped icon 5 included in the map display screen of FIG. 4C) included in the map display screen in the region. , The POI-5 facility information) is stored as second history information in the storage unit 106 (for example, the memory in FIG. 4C), and the first history information stored in the storage unit 106 (for example, In FIG. 4B, the difference facility obtained by comparing POI-3, POI-4, POI-5) and the second history information (for example, POI-5 in FIG. 4C). Information (for example, facility information of POI-3 and POI-4 in FIG. 4 (c)) is a facility icon (for example, in FIG. 4 (c), the star-shaped icons 3 and 4 are exited from the map display area). Facility information corresponding to the facility icon shown) A judgment, the history information file 106a to the determined the facility information as history information (e.g., in FIG. 4 (c), the history information storage means) may further be stored in. As described above, when the scroll operation or the like continues, the facility information is sequentially stored and accumulated in the history information file 106a as history information.

  Thereafter, the history information storage process shown in FIG. 3 is terminated, and the process proceeds to the process of step SA-11 in FIG.

  Returning to FIG. 2 again, the facility information display unit 102e of the terminal device 100 determines whether or not there is a facility display request (step SA-11). That is, the facility information display unit 102e determines whether a facility display request for requesting the display of facility information is input to the user via the input unit 116 by the processing of the facility display request input unit 102g.

  Here, with reference to FIG. 5 and FIG. 7 again, an example of the input of the storage start instruction by the processing of the facility display request input unit 102g will be described. In the operation setting screen shown in FIG. 5 (b), the facility display request input unit 102g gives the user the check box “display on screen” shown in (v) of FIG. The facility display request may be input to the user by making the selection. In addition, in the operation menu screen shown in FIG. 7A, the facility display request input unit 102g uses the input unit 116 to check the “Check POI history” check box shown in FIG. 7A (i). The facility display request may be input to the user by making the selection.

  Returning to FIG. 2, if the facility information display unit 102e of the terminal device 100 determines in step SA-11 that there is a facility display request (step SA-11: Yes), the facility information display unit 102e proceeds to the processing of the next step SA-12. . That is, the facility information display unit 102e displays at least a part of the facility information included in the history information on the display unit 114 when the facility display request is input by the processing of the facility display request input unit 102g in step SA-11. Shift to processing. On the other hand, if the facility information display unit 102e of the terminal device 100 determines in step SA-11 that there is no facility display request (step SA-11: No), then the process ends.

  Then, the facility information display unit 102e of the terminal device 100 determines whether the facility information included in the history information matches a predetermined display condition stored in the display condition file 106c (Step SA-12). Here, as an example, the display condition may include at least one of a facility category, business hours, facility scale, coupon information, and reviews. The display condition may be a distance from the cursor position or the display center position on the map display screen. The display condition may be a distance from the current position based on the current position information acquired by the process of the current position information acquisition unit 102h. The display condition may be the order in which the facility information is stored in the history information file 106a as history information by the processing of the history information storage unit 102d.

On the other hand, if the facility information display unit 102e of the terminal device 100 determines that the display condition is not met in Step SA-12 (Step SA-12: No), the processing is terminated thereafter.

  When the facility information display unit 102e of the terminal device 100 determines that the display condition is met in Step SA-12 (Step SA-12: Yes), the facility information display unit 102e is based on the predetermined display condition stored in the display condition file 106c. At least a part of the facility information included in the history information (for example, a facility list) is displayed on the display unit 114 (step SA-13). Here, the facility information display unit 102e generates a facility list indicating a list of facilities having the facility information included in the history information based on the history information, and displays at least a part of the generated facility list. 114 may be displayed. In addition, the facility information display unit 102e generates a facility list at the same time as the facility information is stored in the history information file 106a as history information by the processing of the history information storage unit 102d in step SA-10, and the generated facility list May be displayed in a list display area provided in a part of the display unit 114. Here, the facility information display unit 102e may display only the facilities based on various display conditions stored in the display condition file 106, or may be sorted in a predetermined priority order. Further, the display order may be arbitrarily sortable by the user via the input unit 116 even after the list is output by the processing of the facility information display unit 102e.

  Here, with reference to FIG. 6 and FIG. 7 again, an example of the facility list displayed by the processing of the facility information display unit 102e in step SA-13 will be described. As shown in FIG. 6, the display unit is provided with a list display area for displaying a facility list in addition to a map display area for displaying a map display screen. In the facility list displayed in the list display area of FIG. 6 by the processing of the facility information display unit 102e, as an example, the facilities corresponding to the facility icons indicated by the star icons 1 and 2 moved to the outside of the map display screen are displayed. A list (for example, POI-1 and POI-2 in FIG. 6) is displayed, and a notation of a distance from the display center position (for example, “XXm” in FIG. 6) is also displayed for each facility. Yes. In addition, as shown in FIG. 7, on the operation menu screen of FIG. 7A, the user checks the “Check POI history” check box shown in (i) of FIG. When selected, the facility information display unit 102e displays a facility list display screen as shown in FIG. In the facility list displayed on the facility list display screen of FIG. 7B, for example, a list of facilities corresponding to the facility icons indicated by the star icons 1, 2, 3, and 4 is displayed from the display center position. They are displayed in the order sorted by distance (for example, POI-3, POI-4, POI-2, POI-1 in FIG. 7B).

  Returning to FIG. 2, the facility information display unit 102 e of the terminal device 100 has a specific facility among the facilities included in the facility list displayed on the display unit 114 in Step SA-13 via the input unit 116. It is determined whether or not it has been selected (step SA-14).

Then, voice guidance may be executed.

  Above, description of an example of a structure of the navigation server 200 in 2nd Embodiment is finished.

[Processing of navigation server 200 (server-driven type)]
Next, an example of processing of the navigation server 200 according to the second embodiment configured as described above will be described in detail with reference to FIG.

  As shown in FIG. 9, first, the map display screen generation unit 202a of the navigation server 200 associates facility information stored in the facility information database 206b with map data stored in the map database 206a. A map display screen is generated by superimposing them at the location of the facility indicated by the facility location information (step SC-1).

  And the map display control part 202g of the navigation server 200 transmits the map display screen produced | generated by the process of the map display screen production | generation part 202a in step SC-1 to the terminal device 100 (step SC-2), and the said map At least a part of the display screen (for example, the map display screen of FIG. 4A) is displayed in the map display area of the display unit 114 (step SC-3).

  And the control part 102 of the terminal device 100 determines whether the change request signal which requests | requires the change of the map display screen displayed on the map display area of the display part 114 in step SC-3 was input (step SC). -4).

  Then, when the control unit 102 of the terminal device 100 determines in step SC-4 that a change request signal has been input (step SC-4: Yes), the process proceeds to the next step SC-5. On the other hand, if the control unit 102 of the terminal device 100 determines in step SC-4 that the change request signal has not been input (step SC-4: No), the control unit 102 returns to the process immediately before step SC-4 and changes the request. The determination process is repeatedly executed until a signal is input.

  And the control part 102 of the terminal device 100 determines with the change request signal (For example, the change request signal produced by the scroll operation of FIG. 4) having been input in step SC-4 (step SC-4: Yes). In step SC-3, the map display screen in the map display area is changed in response to a change request signal for requesting a change in the map display screen displayed in the map display area of the display unit 114 (for example, FIG. 4). (A) is changed to the map display screen shown in FIG. 4 (b)) (step SC-5). Here, the control part 102 of the terminal device 100 acquires the said map data from the navigation server 200, when the part in which the map data is not yet downloaded exists in the map display area of the map display screen after a change. May be.

  Then, the control unit 102 of the terminal device 100 determines whether or not there is a storage start instruction when the map display screen in the map display area is changed in step SC-5 (step SC-6). That is, the control unit 102 instructs to start storing facility information (for example, the check box shown in (iv) of FIG. 5A or the “history” shown in (ii) of FIG. 5B). It is determined whether or not the user has input the “Save” check box and the like via the input unit 116.

  If the control unit 102 of the terminal device 100 determines in step SC-6 that there is a storage start instruction (step SC-6: Yes), the process proceeds to the next step SC-7. On the other hand, if the control unit 102 of the terminal device 100 determines in step SC-6 that there is no storage start instruction (step SC-6: No), the process returns to step SC-4.

  Then, the control unit 102 of the terminal device 100 transmits a storage start instruction signal based on the storage start instruction to the navigation server 200 (step SC-7).

  Then, the history information storage unit 202h of the navigation server 200 receives the storage start instruction signal transmitted by the process of the control unit 102 from the terminal device 100 in step SC-7 (step SC-8). Thereby, when the history information storage unit 202h receives a storage start instruction signal in step SC-7, when the map display screen in the map display area is changed by the process of the control unit 102 in step SC-5, The facility information corresponding to the facility icon included in the map display screen in the map display area is received from the terminal device 100, and the process proceeds to processing for storing the facility information as history information in the history information database 206f.

  Then, when the map display screen in the map display area is changed in Step SC-5, the control unit 102 of the terminal device 100 uses the facility corresponding to the facility icon included in the map display screen in the map display area. It is determined whether there is information (step SC-9). For example, the control unit 102 displays the facility icons (for example, the star-shaped icons 1, 2, 3, 4 in FIG. 4A) on the map display screen in the map display area shown in FIG. It is possible to determine that there is facility information corresponding to the facility icon.

  If the control unit 102 of the terminal device 100 determines in step SC-9 that there is facility information (step SC-9: Yes), the process proceeds to the next step SC-10. On the other hand, the control part 102 of the terminal device 100 returns to the process of step SC-4, when it determines with there being no facility information in step SC-9 (step SC-9: No).

  And the control part 102 of the terminal device 100 transmits facility information to the navigation server 200 (step SC-10). For example, the control unit 102 uses the facility icons (for example, the star-shaped icons 1, 2, 3, and 3 in FIG. 4A) included in the map display screen in the map display area shown in FIG. The facility information corresponding to the facility icon indicated by 4 (for example, the facility information of POI-1, POI-2, POI-3, POI-4 in FIG. 4A) may be transmitted to the navigation server 200. .

  In this embodiment, since the facility information database 206b exists on the navigation server 200 side, the control unit 102 of the terminal device 100 does not have to transmit the facility information itself associated with the facility icon to the navigation server 200. Good. That is, the control unit 102 transmits a facility ID that specifies facility information associated with the facility icon to the navigation server 200, and receives the facility information corresponding to the facility ID received on the navigation server 200 side from the facility information database 206b. It may be extracted.

  And the history information storage part 202h of the navigation server 200 receives the facility information transmitted by the process of the control part 102 from the terminal device 100 in step SC-10 (step SC-11).

  Then, the history information storage unit 202h of the navigation server 200 determines whether or not the facility information received in step SC-11 matches a predetermined storage condition stored in the storage condition database 206g (step SC-12). ). Here, as an example, the storage condition may be at least one of facility category, business hours, facility scale, coupon information, and word of mouth.

  When the history information storage unit 202h of the navigation server 200 determines that the storage condition is met in Step SC-12 (Step SC-12: Yes), the history information storage unit 202h proceeds to the process of the next Step SC-13. On the other hand, if the history information storage unit 202h of the navigation server 200 determines in step SC-12 that the storage condition is not met (step SC-12: No), the history information storage unit 202h returns to the process of step SC-4 on the terminal device 100 side.

  Then, the history information storage unit 202h of the navigation server 200 stores the facility information as history information in the history information database 206f based on the predetermined storage condition stored in the storage condition database 206g (step SC-13).

  Thus, in steps SC-8 and SC-11 to SC-13, the history information storage unit 202h of the navigation server 200 is displayed in the map display area of the display unit 114 of the terminal device 100 by the processing of the map display control unit 202g. When the map display screen in the map display area is changed in response to a change request signal for requesting a change in the map display screen, the facility icon included in the map display screen in the map display area is displayed. Corresponding facility information is received from the terminal device 100, and the facility information is stored in the history information database 206f as history information. Thereafter, the process proceeds to step SC-14 on the terminal device 100 side.

  Here, in addition to the “history information storage process (steps SC-2 to SC-13)” shown in FIG. 9 as described above, as shown in FIG. 10, facilities relating to facilities that have passed over the map display area screen due to the change operation “History information storage processing (steps SD-1 to SD-22)” when information is stored as history information may be performed.

  In FIG. 10, the processes in steps SD-1 to SD-11 are the same as the processes in steps SC-2 to SC-12 in FIG.

  As illustrated in FIG. 10, when the history information storage unit 202h of the navigation server 200 determines that the storage condition is met in Step SD-11 (Step SD-11: Yes), the history information storage unit 202h stores the predetermined information stored in the storage condition database 206g. Based on the storage condition, the facility information is stored in the storage unit 106 as the first history information (step SD-12). That is, the history information storage unit 202h is changed when the map display screen in the map display area is changed by the processing of the control unit 102 of the terminal device 100 in step SD-4 (for example, from FIG. 4A to FIG. b), the facility icons included in the map display screen in the map display area in step SD-10 (for example, stars included in the map display screen of FIG. 4A). Facility information (for example, facility information of POI-1, POI-2, POI-3, POI-4 in FIG. 4A) corresponding to the facility icons indicated by the type icons 1, 2, 3, 4). The facility information is received from the terminal device 100 and stored in the storage unit 206 (for example, a memory in FIG. 4A) as the first history information. Thereafter, the process proceeds to step SD-13 on the terminal device 100 side. Thereafter, the process proceeds to step SD-13.

  Here, in FIG. 10, the processing of steps SD-13 to SD-19 is the same as the processing of steps SC-4 to SC-12 of FIG.

  When the history information storage unit 202h of the navigation server 200 determines that the storage condition is met in Step SD-19 (Step SD-19: Yes), the history information storage unit 202h is based on the predetermined storage condition stored in the storage condition database 206g. The facility information is stored in the storage unit 106 as second history information (step SD-20). That is, the history information storage unit 202h is further updated when the map display screen in the map display area is changed by the processing of the control unit 102 of the terminal device 100 in step SD-14 (for example, from FIG. 4B to FIG. 4 (c) (when changed to the map display screen), the facility icons included in the map display screen in the map display area in step SD-18 (for example, included in the map display screen of FIG. 4 (b)). (For example, POI-3, POI-4, POI-5 facility information in FIG. 4B) from the terminal device 100. The facility information is received and stored in the storage unit 206 (for example, a memory in FIG. 4B) as the second history information. Thereafter, the process proceeds to step SD-21.

  Then, the history information storage unit 202h of the navigation server 200 stores the first history information (for example, FIG. 4A) stored in the storage unit 106 (for example, the memory in FIG. 4) in steps SD-12 and SD-20. ), POI-1, POI-2, POI-3, POI-4) and second history information (for example, POI-3, POI-4, POI-5 in FIG. 4B) are compared. Then, it is determined whether or not there is a difference (step SD-21). Here, the history information storage unit 202h may compare the first history information and the second history information stored in the storage unit 106 at predetermined time intervals.

  When the history information storage unit 202h of the navigation server 200 determines that there is facility information in step SD-21 (step SD-21: Yes), the history information storage unit 202h proceeds to the next step SD-22. On the other hand, if the history information storage unit 202h of the navigation server 200 determines that there is no facility information in step SD-21 (step SD-21: No), the history information storage unit 202h returns to the process of step SD-13 on the terminal device 100 side.

  When the history information storage unit 202h of the navigation server 200 determines that there is a difference in step SD-21 (step SD-21: Yes), the first history stored in the storage unit 106 in step SD-21. The facility icon of the difference between the information obtained by comparing the information and the second history information (for example, the facility information of POI-1 and POI-2 in FIG. 4B) from the map display area. For example, in the history information database 206f (for example, FIG. 4B), the facility information corresponding to the facility information corresponding to the facility icons indicated by the star icons 1 and 2 in FIG. 4 (b), it is stored in the history information storage means (step SD-22).

  The history information storage process shown in the flowchart of FIG. 10 can be similarly applied when the map display screen of FIG. 4C is changed.

  For example, the history information storage unit 202h of the navigation server 200 is changed when the map display screen in the map display area is changed by the processing of the control unit 102 of the terminal device 100 (for example, from FIG. 4B to FIG. 4C ), The facility icons included in the map display screen in the map display area (for example, the star icons 3 and 4 included in the map display screen of FIG. 4B). , 5 (for example, facility information of POI-3, POI-4, POI-5 in FIG. 4B) from the terminal device 100, and the facility information 1 is stored in the storage unit 106 (for example, the memory in FIG. 4B), and when the map display screen in the map display area is changed by the processing of the control unit 102 of the terminal device 100. For example, when the map display screen of FIG. 4C is changed), the facility icons included in the map display screen in the map display area (for example, stars included in the map display screen of FIG. 4C) The facility information (for example, the facility information of POI-5 in FIG. 4C) corresponding to the facility icon indicated by the type icon 5 is received from the terminal device 100, and the facility information is stored as the second history information. First history information (for example, POI-3, POI-4, POI− in FIG. 4B) stored in the unit 106 (for example, the memory in FIG. 4C) and stored in the storage unit 106. 5) and the second history information (for example, POI-5 in FIG. 4 (c)), the difference in facility information (for example, POI-3, POI− in FIG. 4 (c)). 4 facility information) from the map display area The facility information corresponding to the facility icon (for example, the facility icon indicated by the star-shaped icons 3 and 4 in FIG. 4C) is determined as the history information database 206f ( For example, in FIG. 4C, it may be further stored in the history information storage means).

  Thereafter, the history information storage process shown in FIG. 10 is terminated, and the process proceeds to step SC-14 in FIG.

  Returning to FIG. 9 again, the control unit 102 of the terminal device 100 determines whether or not there is a facility display request (step SC-14). That is, the control unit 102 requests a facility display request to display facility information (for example, the “display on screen” check box shown in (v) of FIG. 5B, or ( It is determined whether or not the “confirm POI history check box” shown in i) is input by the user via the input unit 116.

  And when it determines with the control part 102 of the terminal device 100 having a facility display request | requirement in step SC-14 (step SC-14: Yes), it transfers to the process of the next step SC-15. On the other hand, when it determines with the control part 102 of the terminal device 100 not having a plant | facility display request | requirement in step SC-14 (step SC-14: No), a process is complete | finished after that.

  When determining that there is a facility display request in Step SC-4 (Step SC-14: Yes), the control unit 102 of the terminal device 100 transmits a facility display request signal based on the facility display request to the navigation server 200. (Step SC-15).

  Then, the history information storage unit 202h of the navigation server 200 receives the facility display request signal transmitted by the process of the control unit 102 from the terminal device 100 in step SC-15 (step SC-16). Thereby, when the history information storage unit 202h receives the facility display request signal in step SC-16, the history information storage unit 202h is based on the history information stored in the history information database 206f by the processing of the history information storage unit 202h in step SC-13. Then, at least a part of the facility information included in the history information is transmitted to the terminal device 100, and the process proceeds to display on the display unit 114.

  The facility information display control unit 202i of the navigation server 200 determines whether the facility information included in the history information matches a predetermined display condition stored in the display condition database 206h (step SC-17). . Here, as an example, the display condition may include at least one of a facility category, business hours, facility scale, coupon information, and reviews. The display condition may be a distance from the cursor position or the display center position on the map display screen. The display condition may be a distance from the current position based on the current position information acquired by the processing of the current position information acquisition unit 202j. The display condition may be the order in which the facility information is stored in the history information database 206f as history information by the processing of the history information storage unit 202h.

  If the facility information display control unit 202i of the navigation server 200 determines that the display condition is met in Step SC-17 (Step SC-17: Yes), the facility information display control unit 202i proceeds to the process of the next Step SC-18. On the other hand, if the facility information display control unit 202i of the navigation server 200 determines in step SC-17 that the display condition is not met (step SC-17: No), then the process ends.

  When the facility information display control unit 202i of the navigation server 200 determines that the display condition is met in Step SC-17 (Step SC-17: Yes), the facility information display control unit 202i is based on the predetermined display condition stored in the display condition database 206h. Then, at least a part of the facility information included in the history information (for example, facility list) is transmitted to the terminal device 100 (step SC-18) and displayed on the display unit 114 (step SC-19). Here, the facility information display control unit 202i has a facility list indicating a list of facilities having the facility information included in the history information based on the history information (for example, the facility list shown in FIGS. 6 and 7B). May be generated, and at least a part of the generated facility list may be transmitted to the terminal device 100 and displayed on the display unit 114. In addition, the facility information display control unit 202i generates a facility list at the same time that the facility information is stored in the history information database 206f as history information by the processing of the history information storage unit 202d in step SC-13, and the generated facility At least a part of the list may be transmitted to the terminal device 100 and displayed in a list display area (for example, the list display area shown in FIG. 6) provided in a part of the display unit 114.

  Then, the control unit 102 of the terminal device 100 determines whether or not a specific facility has been selected by the user via the input unit 116 among the facilities included in the facility list displayed on the display unit 114 in Step SC-19. Is determined (step SC-20). For example, the control unit 102 determines whether the user has selected the check box shown in (i) of FIG. 6 or the check box shown in (ii) of FIG. judge.

  And when it determines with the control part 102 of the terminal device 100 having selected the plant | facility in step SC-20 (step SC-20: Yes), it transfers to the process of the next step SC-21. On the other hand, when it determines with the control part 102 of the terminal device 100 not having selected the plant | facility in step SC-20 (step SC-20: No), a process is complete | finished after that.

  And when it determines with the control part 102 of the terminal device 100 having selected the facility in step SC-20 (step SC-20: Yes), the facility selection signal based on the designated facility is transmitted to the navigation server 200 ( Step SC-21).

  And the user designated point registration part 202k of the navigation server 200 receives the facility selection signal transmitted by the process of the control part 102 from the terminal device 100 in step SC-21 (step SC-22).

  Then, the user designated point registration unit 202k of the navigation server 200 displays the facility indicated by the facility selection signal received in step SC-22 (for example, “POI-1” shown in FIG. 6 (i), FIG. 7B). The facility information of “POI-4” indicated by (ii))) may be registered in the user designated point database 206i for each user (step SC-23).

  The facility information display control unit 202i of the navigation server 200 then relates to the facility indicated by the facility selection signal received in step SC-22 (for example, “POI-4” indicated by (ii) in FIG. 7B). At least a part of the information (for example, the facility information display screen in FIG. 7C) may be transmitted to the terminal device 100 (step SC-24) and displayed on the display unit 114 (step SC-25).

  Then, the route guidance control unit 202m of the navigation server 200 displays the link “go to this point” shown in (iv) via the input unit 116 on the facility information display screen shown in FIG. When the is selected, a process for executing route guidance up to “POI-4” shown below may be started (steps SC-26 to SC-32).

  Specifically, the control unit 202 of the navigation server 200 selects the facility designated by the user via the input unit 116 among the facilities included in the facility list displayed on the display unit 114 in step SC-25 (FIG. The facility position information corresponding to “POI-4” indicated by (ii) of 7 (b) is acquired (step SC-26).

  Then, the control unit 102 of the terminal device 100 transmits the position information signal received from the position transmission device 500 by the position acquisition unit 112 to the navigation server 200 (step SC-27), and the current position information acquisition unit of the navigation server 200. 202j acquires the position information calculated from the position information signal received from the terminal apparatus 100 as the current position information of the user of the terminal apparatus 100 (step SC-28).

  And the guidance route search part 202c of the navigation server 200 is based on the facility position information and the current position information acquired in Step SC-26 and Step SC-28, and the facility based on the facility position information from the current position based on the current position information. A guide route to (for example, “POI-4” corresponding to the star icon 4) is searched using the network data stored in the network database 206c to generate guide route data (step SC-29). .

  Then, the route guidance information generation unit 202d of the navigation server 200 generates route guidance information including at least the guidance route data generated by the processing of the guidance route search unit 202c in step SC-29 (step SC-30). Here, the route guidance information may include map data of a map including the guidance route stored in the map database 206a. The route guidance information may include guidance data that is stored in the guidance database 206e and that is output at a guidance target point included in the guidance route. Here, the route guidance information storage unit 202f may store in the route guidance information database 206d the route guidance information including at least the guidance route data generated by the process of the route guidance information generation unit 202d in step SC-30.

  Then, the route guidance control unit 202m of the navigation server 200 transmits a route guidance display screen based on the route guidance information generated by the process of the route guidance information generation unit 202d in Step SC-30 to the terminal device 100 (Step SC). -31) The route guidance is executed by causing the output unit of the terminal device 100 to output at least a part of the route guidance display screen (step SC-32). Here, the route guidance control unit 202m transmits voice data corresponding to the guidance route among the guidance data stored in the guidance database 206e to the terminal device 100, thereby outputting the voice data via the voice output unit 118 of the terminal device 100. Then, voice guidance may be executed.

[Processing of navigation device 400 (stand-alone type)]
Next, an example of the process of the navigation device 400 according to the third embodiment configured as described above will be described in detail with reference to FIG.

  As shown in FIG. 12, first, the map display unit 402a displays a facility icon in which facility information stored in the facility information database 406b is associated with map data stored in the map database 406a. A map display screen (for example, the map display screen shown in FIG. 4A) displayed superimposed on the location of the facility to be displayed is generated, and at least a part of the generated map display screen is displayed on the map of the display unit 414. It is displayed in the area (step SE-1).

  Then, the display map changing unit 402b determines whether or not a change request signal for requesting a change of the map display screen displayed in the map display area of the display unit 414 by the processing of the map display unit 402a in step SE-1 is input. Determine (step SE-2).

  When the display map changing unit 402b determines in step SE-2 that a change request signal (for example, a change request signal generated by the scroll operation in FIG. 4) has been input (step SE-2: Yes), The process proceeds to step SE-3. On the other hand, if the display map changing unit 402b determines in step SE-2 that the change request signal is not input (step SE-2: No), the display map changing unit 402b returns to the process immediately before step SE-2, and the change request signal is received. The judgment process is repeatedly executed until input.

  Then, the display map changing unit 402b responds to the change request signal for requesting the change of the map display screen displayed in the map display area of the display unit 414 by the processing of the map display unit 402a in step SE-1. The map display screen in the area is changed (for example, the map display screen shown in FIG. 4A is changed to the map display screen shown in FIG. 4B) (step SE-3).

  Then, the history information storage unit 402c determines whether or not there is a storage start instruction when the map display screen in the map display area is changed by the process of the display map changing unit 402b in step SE-3 (step S3). SE-4). That is, the history information storage unit 402c stores a storage start instruction (for example, the check box shown in (iv) of FIG. 5A) or the storage start instruction that instructs the storage start of facility information through the processing of the storage start instruction input unit 402e. It is determined whether or not the user has input the “save history” check box shown in (ii) of (b) via the input unit 416.

  When the history information storage unit 402c determines that there is a storage start instruction in Step SE-4 (Step SE-4: Yes), the history information storage unit 402c proceeds to the process of the next Step SE-5. That is, when the storage start instruction is input by the process of the storage start instruction input unit 402e in step SE-4, the history information storage unit 402c stores the map information in the map display area by the process of the display map change unit 402b in step SE-3. When the map display screen is changed, the process proceeds to processing for storing facility information as history information in the history information database 406f. On the other hand, when it is determined in step SE-4 that there is no storage start instruction (step SE-4: No), the history information storage unit 402c returns to the process of step SE-2.

  The history information storage unit 402c is included in the map display screen in the map display area when the map display screen in the map display area is changed by the processing of the display map change unit 402b in step SE-2. It is determined whether there is facility information corresponding to the facility icon (step SE-5). For example, the history information storage unit 402c displays the facility icons (for example, the star-shaped icons 1, 2, 3 in FIG. 4A) on the map display screen in the map display area shown in FIG. , 4 may determine that there is facility information corresponding to the facility icon.

  When the history information storage unit 402c determines that there is facility information in Step SE-5 (Step SE-5: Yes), the history information storage unit 402c proceeds to the process of the next Step SE-6. On the other hand, when it is determined in step SE-5 that there is no facility information (step SE-5: No), the history information storage unit 402c returns to the process of step SE-2.

  Then, the history information storage unit 402c determines whether the facility information matches a predetermined storage condition stored in the storage condition database 406g (step SE-6). Here, as an example, the storage condition may be at least one of facility category, business hours, facility scale, coupon information, and word of mouth.

  When the history information storage unit 402c determines that the storage condition is met in Step SE-6 (Step SE-6: Yes), the history information storage unit 402c proceeds to the process of the next Step SE-7. On the other hand, when the history information storage unit 402c determines in step SE-6 that the storage condition is not met (step SE-6: No), the history information storage unit 402c returns to the process of step SE-2.

  Then, the history information storage unit 402c stores the facility information as history information in the history information database 406f based on a predetermined storage condition stored in the storage condition database 406g (step SE-7).

  As described above, in steps SE-4 to SE-7, the history information storage unit 402c performs the process when the map display screen in the map display area is changed by the process of the display map change unit 402b in step SE-3. The facility information corresponding to the facility icon included in the map display screen in the map display area is stored in the history information database 406f as history information. Thereafter, the process proceeds to step SE-8.

  Here, in addition to the “history information storage process (steps SE-1 to SE-7)” shown in FIG. 12 described above, the facility information related to the facility that has passed the map display area screen by the change operation is stored as history information. History information storage processing may be performed.

  That is, when the map display screen in the map display area is changed by the processing of the display map change unit 402b (for example, from the map display screen of FIG. 4A to the map display screen of FIG. 4B). When changed, facility icons included in the map display screen in the map display area (for example, star icons 1, 2, 3, and 4 included in the map display screen of FIG. 4A) The storage unit 406 (for example, facility information (for example, facility information of POI-1, POI-2, POI-3, POI-4 in FIG. 4A) as the first history information corresponding to the facility icon) 4 (a), when the map display screen in the map display area is changed by the processing of the display map changing unit 402b (for example, from FIG. 4 (b) to FIG. 4 (c). ) When changing to the map display screen ), A facility corresponding to the facility icon (for example, the facility icon indicated by the star-shaped icons 3, 4 and 5 included in the map display screen of FIG. 4B) included in the map display screen in the map display area. Information (for example, facility information of POI-3, POI-4, and POI-5 in FIG. 4B) is stored in the storage unit 406 (for example, a memory in FIG. 4A) as second history information. The difference facility information obtained by comparing the first history information and the second history information stored in the storage unit 406 (for example, in POI-1 and POI-2 in FIG. 4B) The facility information) is determined as the facility information corresponding to the facility icon (for example, the facility icon indicated by the star-shaped icons 1 and 2 in FIG. 4B) that has left the map display area, and the determined facility History information as history information Database 406f (e.g., in FIG. 4 (b), the history information storage unit) may be stored in.

  Note that details of the history information storage processing are the same as the processing of “history information storage processing (steps SB-1 to SB-15)” illustrated in FIG. 3 described in the first embodiment, and thus description thereof is omitted. To do.

  Then, the facility information display unit 402d determines whether there is a facility display request (step SE-8). That is, the facility information display unit 402d performs a process of the facility display request input unit 402f to request a facility display request (for example, “display on the screen” shown in (v) of FIG. 5B). It is determined whether or not the user has input a check box or the “check POI history check box” shown in FIG. 7A (i) via the input unit 416.

  If the facility information display unit 402d determines that there is a facility display request in step SE-8 (step SE-8: Yes), the facility information display unit 402d proceeds to the next step SE-9. That is, the facility information display unit 402d displays at least part of the facility information included in the history information on the display unit 414 when the facility display request is input by the processing of the facility display request input unit 402f in step SE-8. Shift to processing. On the other hand, when the facility information display unit 402d determines in step SE-8 that there is no facility display request (step SE-8: No), the processing is thereafter terminated.

  If the facility information display unit 402d determines in step SE-8 that there is a facility display request (step SE-8: Yes), the facility information included in the history information is stored in the display condition database 406h. It is determined whether or not the display conditions are met (step SE-9). Here, as an example, the display condition may include at least one of a facility category, business hours, facility scale, coupon information, and reviews. The display condition may be a distance from the cursor position or the display center position on the map display screen. The display condition may be a distance from the current position based on the current position information acquired by the process of the current position information acquisition unit 402g. The display condition may be the order in which the facility information is stored in the history information database 406f as history information by the processing of the history information storage unit 402c.

  If the facility information display unit 402d determines that the display condition is met in Step SE-9 (Step SE-9: Yes), the facility information display unit 402d proceeds to the process of the next Step SE-10. On the other hand, if the facility information display unit 402d determines in step SE-9 that the display condition is not met (step SE-9: No), then the process ends.

  If the facility information display unit 402d determines that the display condition is met in Step SE-9 (Step SE-9: Yes), the facility information display unit 402d includes the history information based on the predetermined display condition stored in the display condition database 406h. At least a part of the facility information (for example, a facility list) is displayed on the display unit 414 (step SE-10). Here, the facility information display unit 402d displays a facility list indicating a list of facilities having the facility information included in the history information (for example, the facility list shown in FIGS. 6 and 7B) based on the history information. It may be generated and at least a part of the generated facility list may be displayed on the display unit 414. Further, the facility information display unit 402d generates a facility list at the same time as the facility information is stored in the history information database 406f as history information by the processing of the history information storage unit 402c in step SE-7, and the generated facility list May be displayed in a list display area (for example, the list display area shown in FIG. 6) provided in a part of the display unit 414.

  Then, the facility information display unit 402d determines whether or not a specific facility has been selected by the user via the input unit 416 among the facilities included in the facility list displayed on the display unit 414 in Step SE-10. (Step SE-11). For example, the facility information display unit 402d determines whether the user has selected the check box illustrated in (i) of FIG. 6 or the check box illustrated in (ii) of FIG. 7B via the input unit 416. Determine whether.

  If the facility information display unit 402d determines that the facility is selected in step SE-11 (step SE-11: Yes), the facility information display unit 402d proceeds to the process of the next step SE-12. On the other hand, when the facility information display unit 402d determines that the facility is not selected in Step SE-11 (Step SE-11: No), the processing is ended.

  Then, the facility information display unit 402d displays at least a part of the facility information related to the designated facility (for example, the facility information display screen in FIG. 7C) on the display unit 414 (step SE-12).

  As described above, in step SE-8 to SE-12, the facility information display unit 402d determines that the history information is stored based on the history information stored in the history information database 406f by the processing of the history information storage unit 402c in step SE-7. At least a part of the facility information included in the information is displayed on the display unit 414. Thereafter, the process proceeds to step SE-13.

  Then, the user designated point registration unit 402h is input by the user among the facilities included in the facility information (for example, the facility list) displayed on the display unit 414 by the processing of the facility information display unit 402d in step SE-10. The facility information of the facility specified via the unit 416 (for example, “POI-1” indicated by (i) in FIG. 6 and “POI-4” indicated by (ii) in FIG. 7B)) Each may be registered in the user designated point database 406i (step SE-13).

  Further, the control unit 402 of the navigation device 400 selects the link “go to this point” shown in (iv) via the input unit 416 on the facility information display screen shown in (c) of FIG. In this case, the following route guidance processing up to “POI-4” may be started (steps SE-14 to SE-18).

  Specifically, the control unit 402 of the navigation device 400 causes the user to input the input unit 416 among the facilities included in the facility list displayed on the display unit 414 by the processing of the facility information display unit 402d in step SE-10. The facility location information corresponding to the facility designated via the location ("POI-4" indicated by (ii) in FIG. 7B) is acquired (step SE-14).

  Then, the current position information acquisition unit 402g acquires the current position information of the user of the navigation device 400 (step SE-15).

  Then, the guidance route search unit 402i, based on the facility position information and the current position information acquired in Step SE-14 and Step SE-15, from the current position based on the current position information to the facility (for example, The guide route to “POI-4” corresponding to the star-shaped icon 4) is searched using the network data stored in the network database 406c to generate guide route data (step SE-16).

  Then, the route guidance information generation unit 402j generates route guidance information including at least the guidance route data generated by the processing of the guidance route search unit 402i in step SE-16 (step SE-17). Here, the route guidance information may include map data of a map including the guidance route stored in the map database 406a. The route guidance information may include guidance data that is stored in the guidance database 406e and that is output at a guidance target point included in the guidance route. Here, the route guidance information storage unit 402k may store the route guidance information including at least the guidance route data generated by the route guidance information generation unit 402j in step SE-17 in the route guidance information database 406d.
