Volumetric 3-D Displays and Spatial Perception

摘要

We perceive and comprehend a visual world of three spatial dimensions. However, current computer-generated graphical displays generally fail to utilize the full potential of visual perception in that they create and present only flat 2-D images. Methods are described for extending computer-generated displays to provide three-dimensional images, and focus on the recent development of a practical, true volumetric display. The results are summarized for several perceptual experiments, conducted with this volumetric display, designed to further our understanding of the perception of orientation and direction in a displayed three-dimensional volume. The accuracy of perceived orientation and direction is an important issue in considering possible applications for 3-D displays.
