The significance of stereopsis and motion parallax in mobile head tracking environments

Despite 3D TVs and applications gaining popularity in recent years, 3D displays on mobile devices are rare. With low-cost head tracking solutions and first user interfaces available on smartphones, the question arises how effective the 3D impression through motion-parallax is and whether it is possible to achieve viable depth perception without binocular stereo cues. As motion parallax and stereopsis may be considered the most important depth cues, we developed an experiment comparing the user's depth perception utilizing head tracking with and without stereopsis.
