Moving Parallax Barrier Design for Eye-Tracking Autostereoscopic Displays

We present a moving parallax barrier panel with eye- tracking for auto-stereoscopic displays that ensures the viewer has a high degree of movement. The right and left image of auto-stereoscopic display are reversed when the users move horizontally because a general method of parallax barrier is designed to be a fixed type that its location and shape are unchangeable. In this paper a method of the moving parallax barrier design is introduced to supplement a disadvantage of the fixed parallax barrier that provides observation at the specific locations. For making the moving parallax barrier, the cross connector that is constituted with 640 lines FPC is designed. Commercially available web camera is utilized to implement eye-tracking system and shows the experimental result.
