Abstract
A display device includes a projector and a translucent hemispherical screen disposed in a black box, with the axis of the hemisphere extending perpendicular to a surface on which an image from the projector is cast. A semitransparent mirror is disposed on the opposite side of the image-receiving surface of the hemispherical screen, aslant to the axis of the hemisphere and opposite a viewer. The image of an spherical object projected on the hemispherical screen can be seen in stereoscopic spatial vision. The image viewed through the semitransparent mirror appears as if it was floating in space.
