The Effect of Interocular Contrast and Ocular Dominance on the Perception of Motion-in-Depth in 3-D Displays

摘要

This study evaluates the maximum permissible luminance difference between stereo pairs (interocular contrast) consistent with the unambiguous perception of motion-in-depth of objects imaged on binocular 3-D displays. Objective measures (vergence eye movements) and subjective measures (observer responses) of motion-in-depth suggest: (1) that the maximum interocular contrast ratio between stereo pairs should not exceed a value of about 3; (2) that the brighter of the two stereo pairs should be presented to the observer's nondominant eye; and (3) that the observer should be well trained in the use of his 3-D display to optimize his perception of motion-in-depth.
