Abstract: An image display device includes: a first display device configured to output a first image representing an operation part for an apparatus; an imaging element configured to reflect the first image and to form the first image in mid-air as a mid-air image; a first sensor configured to detect an approach of a detection object to the mid-air image and to output a first signal; and a controller configured to output a second signal to the apparatus based on the first signal.

Abstract: An image display device includes an imaging element and multiple light sources. The imaging element reflects light of the multiple light sources and forms multiple floating images in mid-air. The imaging element includes a base member including a first surface, and a reflector array on the base member. The reflector array includes multiple reflector rows including multiple dihedral corner reflectors along a first direction. The multiple reflector rows are arranged parallel to a second direction crossing the first direction. The multiple dihedral corner reflectors each include a first reflecting surface, and a second reflecting surface orthogonal to the first reflecting surface.
