A position 612 is a position of a store or facility of the corresponding POI information of ID 611. Specifically, for example, the position 612 is a mesh ID, XY coordinates, latitude / longitude, and the like. This position 612 is the same as the position 212 in the POI information table 201, the position 312 in the display form information table 301, and the position 412 in the known list 401. The genre 613 is a genre such as a store or facility of the corresponding POI information of ID611. Conventionally, POI information may include type information such as “convenience store” and “gas station”, but this genre 613 is separate from the type information included in the POI information in advance. This is a genre that can be arbitrarily set by the user. Thereby, for example, even POI information belonging to different types such as “Italian” and “Chinese cuisine” can be handled as belonging to the same genre. The arrival flag 614 indicates whether or not it has arrived at the store or facility of the corresponding POI information of ID611. In the example of FIG. 6, the arrival flag 614 “0” indicates that it has not arrived, and the arrival flag 614 “1” indicates that it has arrived. The complete flag 615 indicates whether or not a predetermined number or more of POI information stores or facilities have arrived in the same genre 613.

  Information in the genre list 601 is stored by an operation example described later.

  Next, an operation example will be described.

  First, an example of operation in which the current position calculation unit 151 calculates the current position of the vehicle will be described. As described above, the operation of calculating the current position of the vehicle by the current position calculation unit 151 is the same as that of the conventional navigation system, and thus detailed description thereof is omitted. For example, the current position calculation unit 151 may calculate the current position from the travel direction, distance, map data, and the like acquired by the sensor, or from the position, travel direction, travel direction, etc. received by the GPS receiver 103. May be. In addition, the current position calculation unit 151 may correct the current position calculated from the traveling direction, the distance, the map data, and the like acquired by the sensor, based on the position received by the GPS receiver 103 and the like.

  Next, an operation example for reproducing POI information will be described with reference to FIG.

  The display processing unit 152 receives an instruction for POI information to be reproduced (S701). For this purpose, the display processing unit 152 outputs, for example, a list of POI information to the display 107, the audio output device 108, and the like.

  FIG. 8 shows an example of a screen when a list of POI information is output to the display 107 or the like. In FIG. 8, the screen 801 has an area 811 and an area 812.

  An area 811 displays a map. The display processing unit 152 displays icons in the area 811 by superimposing icons indicating stores, facilities, and the like included in the POI information table on the map. For this purpose, the display processing unit 152 displays the map data in an overlapping manner at the position indicated by the position 312 of each row of the display form information table 301. Here, the display processing unit 152 changes the icon display form according to the reproduction flag 313 and the known flag 314 in each row of the display form information table 301. In this embodiment, whether or not the detailed information has been reproduced (whether the reproduction flag 313 is “0” or “1”) and whether or not the detailed information has been registered in the known list (known flag). The display form is changed depending on whether 314 is “0” or “1”. In the example of FIG. 8, the icon 821 indicates a store, a facility, or the like in a row with the reproduction flag 313 “0” and the known flag 314 “0”. The icon 822 indicates a store, a facility, or the like in a row where the reproduction flag 313 “1” and the known flag 314 “0”.

  An area 812 displays a list of POI information. The information displayed in this area 812 is, for example, the name of a store or facility included in the details 213 of each row of the POI information table 201. In the present embodiment, whether or not to display in the list is changed depending on whether or not it is already registered in the known list (whether the known flag 314 is “0” or “1”). To do. That is, if registered in the known list, the POI information table is not displayed in the area 812. Alternatively, the color or font may be changed depending on whether or not it is already registered in the known list.

  The user specifies one of the icons displayed in the area 811 using the input device 106. Alternatively, the user specifies one of the POI information displayed in the area 812. Thereby, the POI information to be reproduced is designated.

  Note that the display processing unit 152 may link the region 811 and the region 812. Specifically, for example, when POI information is selected in the area 812, the display processing unit 152 may change the display form of an icon indicating the position of the selected POI information in the area 811.

  In FIG. 7, the display processing unit 152 updates the reproduction flag of the designated POI information (S702). Specifically, for example, the display processing unit 152 refers to each row of the display form information table 301, searches for the ID 311 that matches the identification information of the POI information specified in S701, and plays the reproduction flag 313 of the corresponding row. Is “1”.

  Next, the display processing unit 152 reads detailed information of the instructed POI information (S703). Specifically, for example, the display processing unit 152 refers to each row of the POI information table 201, searches for the ID 211 that matches the identification information of the POI information specified in S701, and reads the details 213 of the corresponding row. . As described above, the details 213 include names of stores and facilities, features of services, business hours, telephone numbers, addresses, images, moving images, audio data, and the like.

  The display processing unit 152 outputs the read detailed information (S704). An example of a screen when this detailed information is output to the display 107 or the like is shown in FIG. In FIG. 9, the screen 901 has an area 911. The area 911 displays detailed information including the name of the store, the facility, etc., the characteristics of the service, the business hours, the telephone number, the address, the image, the moving image, etc., read by the display processing unit 152 in the processing of S703. .

  As described above, the display processing unit 152 changes the icon display form according to the reproduction flag 313 of the display form information table 301. Therefore, when the reproduction flag 313 is updated by the above operation example, the icon display form is changed. This makes it easy for the user to recognize which POI information has been reproduced.

  Next, an example of an operation registered in the known list will be described with reference to FIG.

  The known registration processing unit 153 receives an instruction for POI information to be registered in the known list (S1001). Since this specific example is the same as S701 described above, a description thereof will be omitted.

  The known registration processing unit 153 updates the known flag of the designated POI information (S1002). Specifically, for example, the display processing unit 152 refers to each row of the display form information table 301, searches for the ID 311 that matches the identification information of the POI information specified in S1001, and knows the known flag 314 of the corresponding row. Is “1”.

  Next, the known registration processing unit 153 registers the designated POI information as known (S1003). Specifically, for example, the known registration processing unit 153 searches the POI information table 201 for an ID 211 that matches the identification information of the POI information specified in S1001, and reads the position 212 of the corresponding row. Next, the known registration processing unit 153 additionally stores in the known list 401 the identification information of the POI information specified in S1001 and the position 212 read out in the above processing as the ID 411 and the position 412 of the new row. .

  As described above, the display processing unit 152 changes the POI information list and the icon display form according to the reproduction flag 313 and the known flag 314 in the display form information table 301.

  FIG. 11 shows a screen example when the display form information table 301 shown as an example in FIG. 3 and the known list 401 shown as an example in FIG. 4 are obtained by the processing described above. In FIG. 11, the screen 1101 has an area 1111 and an area 1112. The area 1111 corresponds to the above-described area 811 in FIG. Similarly, the region 1112 corresponds to the region 812 in FIG. 8 described above.

  The icon 1121 in the area 1111 indicates the position of the store or facility of the POI information registered in the known list, that is, the store or facility in the row where the known flag 314 is “1” in the known list 401.

  An area 1112 displays a list of POI information. Here, when the known flag 314 of the display form information table 301 is “1”, the display processing unit 152 does not display the name of the store or facility in the POI information table in the row.

  Here, it is assumed that the POI information registered in the known list does not matter whether or not the detailed information has been reproduced, and all the registered items are icons having the same display form. However, the present invention is not limited to this, and even with respect to POI information registered in the known list, the icon display form may be changed depending on whether or not the detailed information has been reproduced.

  As described above, what is registered as known can be prevented from being displayed in the list of POI information. As a result, it is possible to display only a list of POI information such as stores and facilities that the user is not familiar with. Therefore, it is possible to effectively display only POI information that is not well known by the user even on the display 107 having a limited size.

  In addition, it is possible to change the icon display form according to the reproduced detailed information or the registered known information. Therefore, it becomes easy for the user to recognize which store or facility or the like has been referred to and whether or not the place is a familiar place.

  Next, an operation example when registering in the genre list will be described with reference to FIG.

  In FIG. 12, the genre registration processing unit 154 receives POI information to be registered in the genre list and an instruction such as the genre (S1201). For this purpose, the genre registration processing unit 154 outputs, for example, a list of POI information to the display 107, the audio output device 108, and the like. A screen example when a list of POI information is output to the display 107 or the like is the same as that in FIG. The user uses the input device 106 to specify either the icon displayed in the area 811 or the POI information displayed in the area 812. Next, the genre registration processing unit 154 receives an instruction of the genre of the designated POI information. For this purpose, the genre registration processing unit 154 causes the display 107 to display a screen example shown in FIG. In FIG. 13, a screen 1301 includes a button 1311, a button 1312, and the like. A button 1311 is used to instruct to select from already registered genres. A button 1312 is used to instruct to newly register a genre. When the button 1311 is pressed or the like, the genre registration processing unit 154 reads different genres 613 from the genre list 601 and displays the read genres 613 on the display 107. The user uses the input device 106 to select any one of the displayed genres. The genre registration processing unit 154 sets the selected genre as the genre of the designated POI information. When the button 1312 is pressed or the like, the genre registration processing unit 154 causes the display 107 to display a screen for receiving free word input. The user uses the input device 106 to input a genre to be registered. The genre registration processing unit 154 sets the input character string as the genre of the designated POI information table.

  In FIG. 12, the genre registration processing unit 154 registers the accepted POI information table and genre in the genre list (S1202). Specifically, for example, the genre registration processing unit 154 searches the POI information table 201 for an ID 211 that matches the identification information of the POI information specified in S1201, and reads the position 212 of the corresponding row. Next, the genre registration processing unit 154 adds, to the genre list 601, the identification information of the POI information specified in S1201, the position 212 read in the above-described process, and the genre specified in S1201 in the ID 611 of a new row. , Position 612 and genre 613 are additionally stored. Furthermore, the genre registration processing unit 154 stores “0” in the arrival flag 614 and the complete flag 615 in the additionally stored row.

  Thus, when registered in the genre list, a list of POI information stored in the genre list can be output. An example of a screen that outputs this list is shown in FIG. In FIG. 14, an area 1411 of a screen 1401 displays a list of POI information belonging to the genre 613 “spicy” of the genre list 601 shown in FIG. The display processing unit 152 displays an icon 1421 in the area 1411 according to the arrival flag 614 of the genre list 601. In the case of FIG. 14, the display processing unit 152 displays an icon 1421 on the genre list 601 where the arrival flag 614 is “1”. In addition, the display processing unit 152 changes the display form of the icon 1421 in the area 1412 according to the complete flag 615 of the genre list 601. A screen 1401 is an example when the complete flag 615 of the genre list 601 is “0”.

  Next, an operation example when the vehicle arrives at any location will be described with reference to FIG. In addition, although the timing which starts this operation example is arbitrary, it may be every predetermined time, when the navigation system 1 is started, when it arrives at a set destination or waypoint.

  In FIG. 15, the arrival processing unit 155 determines whether or not the vehicle has arrived at any place (S1501). Although this determination condition may be arbitrary, for example, the following can be considered.

(1) When arriving at a set destination or waypoint (2) When a predetermined time (for example, 10 minutes) has elapsed since the engine stopped In the case of (2) above, the previous engine was stopped when the engine was started. The determination may be made based on whether or not a predetermined time has passed.

  If the vehicle arrives at any location as a result of the determination in S1501, the arrival processing unit 155 determines whether or not the arrival position is a position of a store or a facility registered in the genre list (S1502). ). Therefore, for example, when the arrival processing unit 155 performs the determination in S1501 based on the determination condition (1), the arrival processing unit 155 matches the position of the destination or waypoint determined to have arrived at the position 612 of the genre list 601. Judgment is made based on whether or not something to be included is included. In addition, when the determination of S1501 is made based on the determination condition (2) above, the arrival processing unit 155 determines whether any of the positions 612 in the genre list 601 is within a predetermined distance from the current position of the vehicle. To do.

  As a result of the determination in S1502, if the arrival position is a position of a store or facility registered in the genre list, the arrival processing unit 155 updates the arrival flag of the genre list (S1503). For this purpose, for example, the arrival processing unit 155 searches the genre list 601 for a location 612 such as a store or a facility that matches the location arrived in the processing of S1502 described above, and sets the arrival flag 614 of the searched row to “1”. And

  Next, the arrival processing unit 155 determines whether or not a predetermined number or more have arrived at the store or facility in the genre to which the store or facility arrived this time (S1504). For this purpose, the arrival processing unit 155 searches the genre list 601 for a location 612 such as a store or a facility that matches the location arrived in the above-described processing of S1502, and sets the genre 613 of the searched row. read out. Next, the arrival processing unit 155 selects a line including the read genre 613 from the genre list 601 and counts the arrival flags 614 of the selected line being “1”. As a result, when the number of arrival flags 614 “1” in the selected row is equal to or greater than a predetermined number, the arrival processing unit 155 arrives at a predetermined number or more at the store or facility in the genre to which the store or facility arrived this time. It is determined that

  As a result of the determination in S1504, if the genre to which the store or facility arrived this time has arrived at a predetermined number or more, the arrival processing unit 155 updates the complete flag of the genre list (S1505). Therefore, for example, the arrival processing unit 155 sets the complete flag 615 of the row selected in the above-described processing of S1504 from the genre list 601 to “1”.

  As described above, the display processing unit 152 changes the display form of the list icon 1421 in the area 1411 according to the complete flag 615 of the genre list 601. FIG. 16 shows a screen example when the complete flag 615 of the genre list 601 is updated by the above operation example. In FIG. 16, the screen 1601 has an area 1611. The region 1611 corresponds to the region 1411 in FIG. The icon 1621 in the region 1611 is different from the icon 1421 described above.

  As described above, it is possible to change the display form of the icons registered in the genre list according to the number of arrivals at a store or facility registered in the same genre.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design changes and the like without departing from the gist of the present invention. .

  For example, in the above-described embodiment, the position on the map data is indicated by the mesh ID and the XY coordinates, but the present invention is not limited to this. For example, the position may be indicated only by latitude and longitude, or may be indicated only by XY coordinates. Further, it may be indicated by combining other information with latitude, longitude, XY coordinates, and the like.

  Moreover, in the above-mentioned embodiment, although the icon which shows the position of the shop and facility registered into the known list shall change and display a display form, it is not necessarily restricted to this. You may control not to display the icon which shows the position of the shop or facility registered into the known list.

  Further, in the above-described embodiment, when the completion determination is made, the display form of the icons in the list of the genre list is changed. However, the present invention is not limited to this. For example, you may change the display form of the icon displayed on a map.

  A plurality of complete determination threshold values may be set. Specifically, for example, in the genre to which the store or facility that has arrived this time has arrived at a first number or more in the store or facility, the first icon is used, and the second in the store or facility in the same genre. The second icon may be used when more than the number of items has arrived. The number of such thresholds may be arbitrary.

  In the arrival determination, it may be determined that only items that have arrived within a predetermined time from the current date and time have arrived at the store or facility.

  In the above-described embodiment, the change pattern of the display form of the POI information list may be determined in advance, or may be arbitrarily set by the user. Similarly, the icon may be determined in advance or may be arbitrarily set by the user.
