Depth perception in a stereoscopic display as a function of number of stimuli, depth range, and number of scale markers

Abstract

Ss were tested on 2 tasks, ranking dots in order of depth and specifying actual depth in space, to determine the effects of number of stimuli, depth range, and number of scale markers on depth discrimination. When ranking was required, increasing the number of dots presented resulted in decreased accuracy. The number of dots did not affect accuracy when specific depth assignments were required. Increasing the number of dots resulted in significantly greater time to complete the task. As depth range was increased, accuracy improved regardless of task and time scores decreased for the ranking task. Decrease in number of scale markers resulted in increased time and error scores.
