Paper Abstract

In this paper, we propose an eye tracking system using a variable parallax barrier capable of providing the utmost natural stereo images. The variable parallax barrier consists of four sub-barriers, and a new cross connector composed of 640 lines flexible-printed-circuit is designed to create a sub-barrier. A depth camera based on the time-of-flight theory is utilized to implement an eye tracking system for an observer. The variable parallax barrier located in front of a monitor will be operated and controlled electrically through serial communication according to the values of coordinates gained by the camera. We compared the performance of the variable parallax barrier with that of other general systems via computer simulation.
