Tolerance of stereopsis to conjunctive cyclorotation.
Stereopsis is largely unperturbed by various types of eye, head, and target movements. Here, we used a simple setup to investigate the limits of a previously untested type of stimulus motion on stereoscopic depth perception. Clockwise and counterclockwise rotations of an autostereogram were used to describe the limits of stereopsis to roll-tilt. The result showed intact depth perception with stimulus rotation up to approximately 12 degrees, regardless of rotation direction and viewing distance, indicating a tolerant mechanism for stereoscopic processing by the human neural system.
