Three-Dimensional Displays: Perception, Implementation, and Applications.

摘要

This report reviews the current state-of-the-art in three-dimensional display technology. The basic perceptual cues used to perceive the third(depth) dimension are first described, and empirical data bearing on the interaction between these cues are discussed. Generally, when more depth cues are present, a proportionately more salient sense of depth is conveyed. But this additive model breaks down when motion is involved. It is concluded that stereopsis motion, and occlusion are particularly salient cues. Techniques for implementing perspective and stereoptic displays are then described. This discussion is followed by a review of 3 display technology applications in the following areas: flight deck displays, air traffic control, meteorology, teleoperation, and computer graphics. Where available, studies are discussed which contrast the efficacy of 3D with 2D representations. In both laboratory and field studies, it appears that the usefulness of stereopsis is diminished and may vanish altogether when displays are dynamic.
