On the Gain of
Stereoscopic Motion Parallax Reproduction
Abstract:This paper deals with the reproduction of stereoscopic motion parallax focusing on the ratio
of camera movement to head movement ("gain of motion parallax control"). Within the
framework of a Human Factors study the experimental task of test subjects was to adjust the
gain of motion parallax to perceive a stable and natural stereoscopic image. Earlier experiments
at HHI had shown some deviations from theory which says that, in order to perceive an undistorted stereoscopic space and in order to avoid apparent movements, the gain has to be 1.
The influence of delay time, which may play a major role especially with satellite links, on the
preferred gain was examined as well. No clear dependency of the adjusted gain on delay time
could be found. However, the assessed stability of the displayed scene decreased with
increasing delay times.
