Abstract: A delivery control device generates a recognition index on a notification space basis, the recognition index used to recognize the notification space, displays the recognition index in the notification space, and stores the recognition index in management information. The delivery control device instead stores an image characteristic extracted from a content to be displayed in the notification space as the recognition index in the management information. In this state, the delivery control device selects a notification space viewable on the augmented reality display terminal based on information on the position of the augmented reality display terminal held by a user and information on the position of the notification space and transmits the recognition index corresponding to the selected notification space and a notification content to the augmented reality display terminal.

Abstract: A server (20) as an information presentation device according to the present disclosure includes a route search unit (23) that searches for the moving route, and a route information forming unit (24) as an information presentation unit that, in a case where the searched moving route includes a plurality of partial routes having different moving means, adds congestion information regarding a congestion status of the moving route as a whole according to a congestion degree of each of the plurality of partial routes to the moving route and presents the congestion information to the user.

Abstract: A position where a user is located can be estimated easily and quickly. When a hold detection unit 122 detects that the user holds a mobile terminal 100 by hand to use the mobile terminal 100 that is held by at least one hand of the user when used by the user and has a camera 130 on the surface facing the ceiling when used by the user, the estimation unit 240 estimates a position where a ceiling is located as the position where the user is located by using an image of the ceiling captured by the camera 130.

Abstract: Information relating to each link based on location information of a user can be generated with high accuracy even without measuring the location information at a high frequency. A map matching unit (101) associates location information of a moving user at each time with pedestrian network data (120) formed by a plurality of nodes and links connecting the nodes through a map matching process, and a calculation unit (102) calculates a passage record of a link of interest as link information based on whether or not the link of interest is connected to preceding and succeeding links in a link row acquired by aligning the links with which the location information is associated in order of times of pieces of the location information.

Abstract: An input unit receives an input of posted information including information regarding passage of links which connect sites in a geographic network. A posted information credibility determination unit (30) determines credibility of the posted information by comparing movement features obtaining from the posted information with movement features obtained in advance with regard to the links in the geographic network and obtained from movement results during the passage of the links.
