A technique for precise depth representation in stereoscopic display

In observing a 3D virtual object displayed stereoscopically on a large-sized screen, there often exists a difference between the calculated depth and the perceived one of the object. This paper presents a method for reducing such differences of depth. This is performed by modification of both the viewing position and the screen position in stereoscopic calculation. The optimal amount of modification was decided using sample values of depth differences. Effectiveness of the proposed method is discussed with the experimental results
