INFORMATION PROVISION DEVICE, INFORMATION PROVISION METHOD, AND CARRIER MEDIUM STORING INFORMATION PROVISION PROGRAM

An information provision device (200) and an information provision method. Each of the information provision device (200) and information provision method includes projecting (230) an image light (L) to a light transmission member (302) so as to display a for-driver information image, sensing (100, 500)a relative distance of an object to be detected existing around the mobile object (301) in the direction of travel, detecting (150) a location of a viewpoint of the driver (300), and changing (250) a position at which an object image indicating the object to be detected is displayed according to a result of the detecting (150) so as to change a perception distance of the driver (300) influenced by a motion parallax of the object image according to the relative distance of the object to be detected in the direction of travel.
