Abstract

The effective use of stereoscopic display systems is dependent, in part, upon reliable data describing binocular fusion limits and the accuracy of depth discrimination for such visual display devices. In two experiments, these issues were addressed as were the effects of interocular crosstalk. Results showed that the limits of fusion were approximately 27.11 minutes of arc for crossed disparity and 24.21 minutes of arc for uncrossed disparity. Crosstalk had no effect on fusion limits for the contrast ratio and stimulus configuration used. Crosstalk also did not affect accuracy in discriminating disparities within the fusion limits. Subjects were extremely accurate in distinguishing relative distances among four groups of stimuli and were able to identify a pair of stimuli located at the same depth plane within each group. However, crosstalk affected subjects' vergence responses as well as subjective ratings of image quality and the conspicuity of ghost images.
