Human factors of 3‐D displays

Abstract

This paper provides a selected review of a number of important perceptual and humanfactors issues that arise when 3-D displays are designed and used. This review and analysis draws heavily from the basic vision literature in order to help provide insight for future design solutions for 3-D displays. Issues discussed include (1) the basics of human stereopsis, (2) interocular crosstalk, (3) oculomotor responding and distance scaling of binocular disparity information, (4) accommodativevergence mismatch, and (5) stereoanomly. The paper concludes with a presentation of several recommendations for the design of 3-D displays.

Towards a New Quality Metric for 3-D Synthesized View Assessment

“…Firstly, 3DTV technology relies on the stereopsis phenomenon. This designates the fact that the human brain fuses two slightly different images, presented on each eye, and interprets the 3-D content [15]. As a result, 3-D displays should provide the appropriate stereoscopic images to ensure depth feeling.…”

Effects of Viewing Displays from Different Distances on Human Visual System

“…The viewing distance and viewing time are considered significant contributing factors to the visual fatigue associated with 3D displays [30][31][32][33]. The viewing distance is considered an essential environmental condition and is described in the guidelines for video display terminals (VTDs) [30].…”

A 2D/3D switchable autostereoscopic display system, an acousto-optic lens approach

“…By the principle of refraction, the left and right images are projected onto the viewer's left and right eyes, respectively, in the horizontal direction. Under this condition, a viewer can perceive a 3D imaging based on the principle of binocular vision [15].…”
