Eye Tracking in Visible Environment

Eye tracking is the process of measuring either the point of gaze or the motion of an eye relative to the head. To make the eye pupil more clearly, in the eye tracking relevant study, most of them introduced the infrared light as a light source. In this paper, we propose an approach of eye tracking system in visible environment base on computer vision. The method contains eye positioning, and eye tracking. The experimental results show that whether students are in turning head, blinking, squinting, forward or backward movement, the eyes can be tracked accurately.
