Effect of Projective Distortions on Perception of Graphic Displays.

Abstract

Graphic displays can provide accurate representations of three-dimensional space only if they are viewed from the geometric center of projection. Other viewing conditions result in distortions of virtual space. A current paradox of graphic display perception is that such distortions are not always evident in perception of depicted space. This paper presents an analysis of the geometric basis for distortions of the virtual space depicted in pictorial displays. Recent experiments are summarized which define the conditions under which geometric distortions affect perceived space. Under some conditions, an active perceptual compensation process exists which discounts the compression and expansion of virtual space. In addition, regularity or familiarity of the viewed object greatly reduce the sensitivity to distortion of spatial information. (Author)
