3-D Display using Motion Parallax for Extended-Depth Perception

This paper proposes a new 3D display that can express differences between depths at extended distances of over tens of meters to meet new requirements for outdoor use. We attempted to use motion parallax for observers to perceive depth because this works as a cue at longer distances where binocular parallax, which is used in conventional 3D displays to perceive depth, does not work. We conducted subjective tests using a moving car in which observers viewed a test pattern overlapping the real view ahead of the car seen through the windshield to examine the feasibility of the 3D display we propose. The experimental results revealed that the perceived depth of a pattern could be controlled by changing its rate of expansion, demonstrating the feasibility of a 3D display for extended-depth perception using motion parallax.
