Abstract
A stereoscopic display method or system includes an image display panel, object tracking sensors, and a means to create first or left, and second or right stereoscopic images based upon viewpoint location. This allows the user to perceive the viewed 3D stereoscopic image as approximately fixed in space.A first embodiment employs differently filtered colored, stereoscopic images. The first and second differently filtered colored images may be perceived as a 3D stereoscopic image by applying anaglyph glasses.In a second embodiment the method of passively polarized glasses may be applied with the result being a stereoscopic image whose location is approximately fixed in space.A third embodiment employs passively polarized anaglyph glasses. This provides the advantage of allowing two different viewers to see different virtual 3D stereoscopic images whose location remains approximately fixed in space.By employing tracking sensors, user gesturing or pointing may now allow interaction with the virtual 3D stereoscopic images in much the same way 2D objects are manipulated by employing a touch screen. This may be combined with voice commands. This allows for input systems such as virtual 3D…
