Stereoscopic motion, as introduced by Béla Julesz in his book Foundations of Cyclopean Perception of 1971, is a translational motion of figure boundaries defined by changes in binocular disparity over time[1] in a real-life 3D scene, a 3D film or other stereoscopic scene.
Alternatively, the images with the binocular motion stimuli can be artificially created, for instance using dynamic random dot stereograms.
By definition, individuals who have only monocular vision do not perform stereoscopic motion processing.
[4] Purely binocular motion stimuli appear to influence also stereoblind persons as far as their sensation of self-motion is concerned.
[5] Using dynamic random dot stereograms presented using a virtual reality head-mounted display, it was demonstrated from subjects' performance on real-world tasks of ball catching and obstacle avoidance that stereoscopic motion can derive from purely binocular stimuli, that is, without requiring any first-order motion perception.
