Observer Compensation for Projective Distortion 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. In our earlier reports we have proposed two processes by which the perceptual system discounts these distortions: an active compensation and a passive categorization. The present report describes 3 sets of studies which demonstrate the nature of these processes. In the first experiment, observers made magnitude estimate judgments of the depth of unfamiliar, 7-sided objects. Distortions were induced by moving the center of projection. Judgments corresponded almost completely with the distorted virtual space. In the second experiment, distortions were induced by moving the observer. No effect of the distortions were found in this situation indicating perfect perceptual compensation. These results replicate and extend our earlier findings. (Author)
