Patent ID: 7492523

Claim:
A method for displaying a three-dimensional scene to a viewer, said method comprising: simultaneously presenting to both eyes of a viewer a first image that is generally planar; simultaneously presenting to both eyes of a viewer a second image that is generally planar and is co-aligned with said first image along an axis that is in the general direction of the viewer but at a perceptibly different distance from the viewer than said first image; wherein the one of said images that is at a distance closer to said viewer depicts objects in the foreground of said three-dimensional scene and the other of said images depicts objects in the background of said scene, and wherein said first image and said second image are presented alternatingly to a viewer with a cycle that is within the time frame of persistence of vision, whereby the viewer observing said images perceives the depicted objects as part of a scene having real depth wherein at least one rotating member is utilized to rotate optical elements so that said viewer is presented with said first and second images at different distances from the viewer.
