Effects of Optical Magnification on the Perception of Displayed Orientation.

Abstract

Two experiments are reported that assess distortions of perceived surface orientation as a result of geometric distortions of two-dimensional spatial displays. Optical magnification (defined in terms of the ratio of actual to geometrically correct viewing distance) greatly affected perception of surface orientation when no consistent information was available for the magnitude of spatial distortion. However, when magnification was caused by (and perfectly correlated with) viewing distance, observers were able to totally compensate for or discount the effects of the geometric distortion of space. Compensation for spatial distortion is dependent on the means by which such distortions are produced. Implications of these results and the compensation process are discussed. (Author)
