Investigating The Relationship Between Binocular Disparity, Viewer Discomfort, And Depth Task Performance On Stereoscopic 3d Displays, John Paul Mcintire

Stereoscopic 3D (S3D) displays offer the capability to enhance user performance on a variety of depth tasks. However, the benefit derived from viewing S3D depends in part on the magnitude of binocular disparity that is displayed. Surprisingly few studies have directly investigated the relationship between disparity and depth task performance. The studies that have been conducted suggest that a minimum amount of disparity (10-50 arc min) may be needed to improve performance over conditions in which no S3D is present, but it is unclear the extent to which performance might improve with increases in disparity beyond this range.
