Abstract:
1. A three dimensional (3D) imaging system configured to display an autostereoscopic image of a scene toward a viewing area, and detect gestures occurring in the viewing area, said system comprising: an imaging device configured to project through a lens a plurality of projected images in distinct directions toward a projection field, wherein each projected image is characterized as a distinct perspective view of the scene, said imaging device also configured to detect through the same lens a plurality of received images from the distinct directions; a holographic diffuser; and a mirror arrangement fixedly positioned in the projection field, said minor arrangement configured to reflect the plurality of projected images from the imaging device toward the holographic diffuser in a manner effective to display an autostereoscopic image of the scene in the holographic diffuser, and reflect a plurality of perspective images from the viewing area toward the imaging device such that each received image corresponds to a distinct perspective view of the viewing area.
