Abstract
Autostereoscopic displays offer users the unique ability to view 3-dimensional (3D) imagery without special eyewear or headgear. However, the users' head must be within limited "eye boxes" or "viewing zones". Little research has evaluated these viewing zones from a human-in-the-loop, subjective perspective. In the first study, twelve participants evaluated the quality and amount of perceived 3D images. We manipulated distance from observer, viewing angle, and stimuli to characterize the perceptual viewing zones. The data was correlated with objective measures to investigate the amount of concurrence between the objective and subjective measures. In a second study we investigated the benefit of generating stimuli that take advantage of monocular depth cues. The purpose of this study was to determine if one could develop optimal stimuli that would give rise to the greatest 3D effect with off-axis viewing angles. Twelve participants evaluated the quality of depth perception of various stimuli each made up of one monocular depth cue (i.e., linear perspective, occlusion, haze, size, texture, and horizon). Viewing zone analysis is discussed in terms of optimal viewing distances and viewing angles. Stimuli properties are discussed in terms of image complexity and depth cues present.
