Perceptual biases in spatial judgements as a function of eyepoint elevation angle and geometric field of view

Research output: Contribution to journal › Conference article › peer-review

Abstract

This study investigated perceptual biases in spatial judgments as a function of the computer graphics eyepoint elevation, monoscopic or stereoscopic display, and target cube location. The display for this experiments consisted of two computer-generated cubes located above a grid plane with drop lines to the display surface. The experiment task consisted of judging azimuth and elevation angles between the target and reference cubes. The results indicated that azimuth errors varied with eyepoint elevation and were maximized at the-15 degree eyepoint, elevation errors were worse using the 75 degree eyepoint, and binocular disparity did not aid judgments of azimuth and elevation.
