The navigation device 12 includes a map information storage unit 1201, a preference information storage unit 1202, a reception unit 1203, a map information acquisition unit 1204, a route information generation unit 1205, a point information acquisition unit 1206, a point information transmission unit 1207, and a post information reception unit 1208. The preference posting information acquisition unit 1209 and the output unit 1210 are provided.

  The storage unit 111 stores one or more pieces of post information. The posted information is information transmitted (posted) by the user to the server device 11. The posted information is, for example, a comment posted to the SNS. The comment is, for example, a comment on a predetermined theme (for example, an interesting television program, a recommended tourist spot, a traffic jam situation in various places, etc.), or a user's arbitrary comment (tweet). In the case of a comment on a predetermined theme, the post name usually corresponds to the theme name.

  In addition, the post information is usually associated with point information indicating a point. The point is usually a point on the map. Moreover, the said point is a station, a facility, a landmark, a sightseeing spot, a temple, a temple, a restaurant, other buildings, etc., and may be called what is called a point. The point information includes, for example, point position information which is position information indicating the position of the point on the map, point name information indicating the name of the point on the map, a point identifier for identifying the point, and the like. The position information is usually longitude and latitude information indicating longitude and latitude, but may be coordinate information indicating coordinates on a map, altitude information indicating altitude, and the like. The point identifier is usually an ID, but may be point name information.

  The posted information includes information for identifying the terminal device (such as a mobile phone or a smartphone) used when the user posted the posted information, information indicating the date and time of the posting, and identifying the posted user. Information to be used may be associated.

  The receiving unit 112 receives one or more pieces of point information indicating points on the map from the navigation device 12. The point information may be a different type of information from the point information associated with the posted information. Hereinafter, the spot information received by the receiving unit 112 is referred to as reception spot information.

  The acquisition unit 113 acquires one or more pieces of post information corresponding to one or more pieces of reception point information from the storage unit 111.

  For example, when one piece of reception point information has point position information, the acquisition unit 113 normally acquires one or more pieces of post information associated with the point position information corresponding to the point position information. The term “corresponding to the location information” means that the location is the same as the location indicated by the location location information, that it is a neighborhood, or a neighborhood. It should be noted that being near or being near may be so close that the distance between the positions satisfies a predetermined condition. The determination of whether or not they are the same, the determination of whether or not they are in the vicinity, and the determination of whether or not they are in the vicinity are well known, and thus detailed description thereof is omitted.

  In addition, for example, when one piece of reception point information has point name information, the acquisition unit 113 normally acquires post information corresponding to the point name information. The “corresponding to the spot name information” usually means that the spot name information is included, but it may mean that the same spot name information as the spot name information is associated.

  The map information acquisition unit 1204 acquires map information from the map information storage unit 1201 in response to the map output instruction received by the reception unit 1203. For example, the map information acquisition unit 1204 acquires map information centered on the position indicated by the center position information included in the map output instruction, map information of the area indicated by the area information included in the map output instruction, and the like. Since the method and procedure for acquiring the map information are well known, detailed description is omitted.

  The route information generation unit 1205 generates route information according to the route generation instruction received by the reception unit 1203. The route information is information indicating a route. The route information usually indicates a route from the departure place to the destination. Further, the route information may indicate, for example, a route from the departure point to the destination via the waypoint. The departure place is indicated by departure point information included in the route generation instruction. The destination is indicated by the destination point information included in the route generation instruction. Further, the route point is indicated by route point information included in the route generation instruction. The route information usually includes point information indicating one or more points on the route. Further, the route information includes road information indicating roads connecting the one or more points, for example.

  For example, the route information generation unit 1205 generates route information with the point indicated by the departure point information included in the route generation instruction as the departure point and the destination indicated by the destination point information included in the route generation instruction as the destination. In addition, the route information generation unit 1205 uses, for example, the point indicated by the departure point information included in the route generation instruction as the departure point, the point indicated by the route point information included in the route generation instruction, and the destination point included in the route generation instruction. Route information with the destination indicated by the information as the destination may be generated. Further, the route information generation unit 1205 normally generates route information by searching for a route from the departure point to the destination or a route from the departure point to the destination via the waypoint by so-called route search. . Since the route search is well known, detailed description is omitted.

  The spot information acquisition unit 1206 acquires one or more spot information. The point information acquisition unit 1206 normally acquires one or more pieces of point information included in the map information acquired by the map information acquisition unit 1204. For example, when the route information generation unit 1205 generates route information, the point information acquisition unit 1206 may acquire one or more pieces of point information included in the route information. When the reception unit 1203 receives a point selection instruction, the point information acquisition unit 1206 may acquire one or more pieces of point information corresponding to the point selection instruction from the map information storage unit 1201. “Corresponding to the point selection instruction” is to acquire the point information corresponding to the point information included in the point selection instruction or the point information corresponding to the point identifier. Further, the spot information acquisition unit 1206 may acquire spot information indicating the current position.

  For example, when the point selection instruction has point information, the point information acquisition unit 1206 acquires the point information corresponding to the point information from the map information storage unit 1201. For example, the point information acquisition unit 1206 acquires one or more pieces of point information having point position information corresponding to the point position information included in the point information from the map information storage unit 1201. For example, the point information acquisition unit 1206 acquires one or more pieces of point information having point name information corresponding to the point name information included in the point information from the map information storage unit 1201.

  “Corresponding to the location information” means that the location is the same as the location indicated by the location location information, is nearby, is nearby, and the like. It should be noted that being near or being near may be so close that the distance between the positions satisfies a predetermined condition. The determination of whether or not they are the same, the determination of whether or not they are in the vicinity, and the determination of whether or not they are in the vicinity are well known, and thus detailed description thereof is omitted. Further, “corresponding to the spot name information” usually means the same as the spot name information, but it may mean that the spot name information is included.

  Further, the point information acquisition unit 1206 may acquire only point information at the same position as the position indicated by the point position information included in the point selection instruction, or may be in the vicinity or vicinity of the position indicated by the point position information.
