Hue and Disparity Interactions in Advanced Stereoscopic Aircraft Displays

Abstract

With the increased complexity of aircraft systems and their environment, 3-D stereoscopic system/control displays will offer great advantage over conventional two-dimensional (2-D) displays by presenting information more consistent with the pilot's 3-D perceptual experience and stereotypes. For such displays the interaction of Chromostereopsis (perceived depth created by hues) and stereopsis (depth effect created by disparity between the left and right visual fields of the observer) is important. The purpose of this research is to evaluate the interaction of chromostereopsis and artificially stimulated stereopsis on a stereoscopic CRT by determining the level of accuracy with which subjects can properly interpret the relative depth differences of adjacent symbols containing one of a combination of six levels of hue and seven stereoscopic disparities.

This research demonstrated that hue, disparity, and the interaction of hue and disparity significantly influenced one's perception of depth on a stereoscopic monitor and that caution should be exercised by the stereoscopic 3-D display format designer when choosing hues to represent images located in close proximity on a stereoscopic display.
