Abstract
An aerial image display device includes an image display unit to display an image; an aerial image formation optical system to cause diffuse light emitted from the image display unit to form an image again in a different space by reflecting the light multiple times and allowing the light to pass through; and processing circuitry to acquire viewpoint position information on an observer viewing a point where the diffuse light is caused to form the image again by the aerial image formation optical system, and to control the image from the image display unit depending on an angle formed by a straight line connecting an end point of a retroreflective sheet and an eye of the observer and a straight line extending from the eye of the observer and reaching the retroreflective sheet right in front.
