A review of the facts about human stereo vision leads to the conclusion that the human stereo processing mechanism is very flexible in the presence of other depth cues. Stereopsis seems to provide only local additional depth information, rather than defining the overall 3D geometry of a perceived scene. This paper reports on an experimental approach to adjusting stereo parameters automatically and thereby providing a low eye strain, easily accommodated stereo view for computer graphics applications. To this end the concept of virtual eye separation is defined. Experiment 1 shows that dynamic changes in virtual eye separation are not noticed if they occur over a period of a few seconds. Experiment 2 shows that when subjects are given control over their virtual eye separation, they change it depending on the amount of depth in the scene. Based partly on these results, an algorithm is presented for enhancing stereo depth cues for moving computer generated 3D images. It has the effect of d...
