INFORMATION DISPLAY DEVICE AND INFORMATION DISPLAY PROGRAM

An information display device acquires information about the current location of the device and information about the orientation of the device when the device is directed to a targeted ground object. A map information storage unit stores map information and a target ground object identification execution unit identifies, on a map, the targeted ground object by use of the current location and orientation information. A specific information acquisition unit acquires specific information relating to the target ground object; and a related information acquisition unit acquires related information relating to the targeted ground object by using a search process based on the specific information. The target ground object identification execution unit identifies, from among the ground objects on the map that are located in the direction in which the information display device is directed, the closest ground object to the current location of the information display device on the map.
