A 3-D Display System Using Motion Parallax
Motion parallax was described as a cue to depth over 300 years ago. Despite this long history, little research has been addressed to it in comparison to binocular parallax. In recent years experimental interest in motion parallax has increased, following the re-discovery of the idea of yoking stimulus motion to head movement. Exploiting what is now known about observer-produced parallax, we propose a novel display system in which 3-D perception results from synchronizing the movement of stimuli on a 2-D screen to observers’ side-to-side head movements, or back and forth head rotations. After briefly reviewing the relevant literature, this chapter suggests how one might go about creating such a display system.
