Patent ID: 7787009

Claim:
An apparatus comprising: an autostereoscopic display; a motion tracking system configured to track a 3D motion of a user within an interaction volume as the user interacts with the autostereoscopic display, and to generate 3D tracking data containing position information about the 3D motion; and an imaging system configured to process the 3D tracking data to generate therefrom an image for display on the autostereoscopic display, wherein the motion tracking system comprises a first video camera and a second video camera, the first and second video cameras configured to generate a plurality of video frames of the 3D motion; and wherein the motion tracking system further comprises a processor configured to process the plurality of video frames to extract therefrom the position information about the 3D motion, wherein the interaction volume is defined by a field-of-view of the first video camera and by a field-of-view of the second video camera, wherein the 3D motion comprises: at least one of: a 3D motion of an optical marker that is held and moved by the user; and a 3D motion of a portion of the user's anatomy that is moved by the user, wherein the position information comprises 3D spatial coordinates of a center of one of the optical marker and the portion of the user's anatomy, wherein the processor is configured to use a tracking algorithm to analyze the plurality of video frames so as to find the 3D spatial coordinates of the center in each of the plurality of frames, wherein the imaging system comprises a virtual imaging system, wherein the virtual imaging system comprises: an image acquisition subsystem configured to use the 3D tracking data to create in virtual space a virtual scene representing the interaction of the user with the autostereoscopic display; and a graphics subsystem configured to interlace a plurality N of views of the virtual scene to generate an interlaced image to be displayed on the autostereoscopic display.
