  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.

There is no limitation on the method and the output method and method. For example, the output unit 1211 may output the posted information on a map indicated by the map information, or may output the posted information in a region different from the region where the map information is output. Good.

  Further, the output unit 1211 may output the posted information so that the posted information receiving unit 1209 can recognize that the posted information is newly received, for example. In other words, in order to distinguish the post information being output from the newly output post information (allowing the user to discriminate between the post information already output and the newly output post information. Because). For example, the output unit 1211 may output the post information being output and the post information to be newly output with different colors, characters, and output areas.
