    Autostereoscopic Display for an Unconstrained Observer

Description:


    In this display, observers can freely change position, rotate their heads, and maintain a true stereoscopic view without using special eyewear. Since no fixed parallax barrier geometry could accommodate arbitrary observer position and orientation, the system creates a dynamically varying parallax barrier that continually changes the width and positions of its stripes as the observer moves. Large stripes would be easily seen by the unaided eye, so the system rapidly animates them in a lateral direction. Each stripe is composed from some number of very slender microstripes, each of which is a switchable LCD element. The result: a stereoscopic display that is continually exact for one moving user, as long as their eye position is tracked.
