1. A floating image interaction device, comprising:
- distortion-free imaging optical system including a surface at which paths of light rays are bent by means of mirror surface reflection; and
a user object detecting means,wherein for an object to be projected placed to one side of said surface, said imaging optical system forms a real image of said object on the opposite side of said surface with front and back being reversed,the imaging optical system is for forming a two-dimension real image of a two-dimension object to be projected, and a three-dimensional real image of a three-dimension object to be projected;
the real image can be observed from oblique direction of the surface;
and said user object detecting means capable of detecting the position, or the position and shape of user objects approaching said real image.

Abstract
A floating image interaction device includes an imaging optical system projecting a floating real image of an object and an user object detecting means for obtaining information about the user accessing the floating real image; means to realize interactive response by the real image or by haptic feedback to actions by the user; and related computer programs.

20. A floating image interaction device, comprising:
-
a substrate including a plurality of dihedral corner reflectors, the substrate transmitting light rays therethrough in a distortion-free manner such that the light rays are bent by the dihedral corner reflectors by means of mirror surface reflection, the substrate having a first surface and a second surface, wherein when an object to be projected is placed at a side of the first surface, an real image is formed reversely at a side of the second surface; and a user object detecting means for detecting position or shape of the object.
