English Abstract

A non-compulsory gaze tracking system based on pupil detection was introduced. The system takes the image of the eye of the tested subject when he is gazing at a position, and processes the eye image to get the relative position of the pupil in the eye, then calculates out the gaze position where he is gazing at. A two-dimension calibration algorithm is employed to calibrate the system, and an angle correction method is proposed to improve the precision of the system. The experimental results under the same conditions show that the calculated gaze positions by the system mostly agree with the real gaze positions, the average error of the view angle is 2.5º, so the system can meet the requirement of common gaze tracking.
