Paper Abstract

Previously reported research has illustrated the dependence of stereoscopic utility on the figures of merit selected as well as the display application. This paper reports on a subsequent experiment in which subjects not only judged the relative depth ordering and subjective quality of planar symbols in a 3-D plan view display, but also manipulated a 3-D cursor. The 3-D images were presented on a Tektronix SGS 620 field-sequential stereoscopic CRT (19-inch diagonal, 120-Hz field rate, passive glasses). Three sources of depth information (cue types) were combined factorially to construct exemplary 3-D images: relative size (angular subtense decreased with increasing depth); stereo (binocular disparity varied from crossed to uncrossed with increasing depth); and luminance (luminance decreased with increasing depth). In addition, depth cue salience and display complexity were included in the factorial design. Inclusion of each of the three depth cues produced significantly faster depth judgments, more accurate cursor positioning, and improved image quality ratings. While the use of multiple depth cues had a complementary effect on performance and image quality ratings (i.e., more was better), the effects were clearly interactive rather than strictly additive.
