Depth Presentation Position of Stereoscopic Displays with Different Screen Sizes and Viewing Distances

Abstract

This research investigates the effect of viewing conditions on depth perception under the conditions that the same stereoscopic images are presented on different stereoscopic displays. Such conditions often occur in practical situations. We measured the differential limens and the point of subjective equality Using three common types of stereoscopic displays in psychophysical experiments. The experimental results showed two properties of depth perception based on the differences among the stereoscopic displays. One is the tendency that the depth is perceived to be closer than the depth presentation position when the position is far away, i.e., at a distance over roughly 800 cm. The other has been obtained from analysis of variance to be roughly 15 min in the disparity angle of the stereoscopic images as the differential limens, which is in the vicinity of the points of subjective equality.
