Abstract :
An eye-gaze tracking system-EyeSecret for real scene, is developed based on pupil-cornea reflection vector method. The general structure and software design are introduced. In the hardware of EyeSecret, design and optimization of optical system and control circuits were proposed. In the software, implementation algorithms of key modules, cornea reflection detection, pupil center extraction and calibration, etc, were described. Besides, deviation of EyeSecret was analyzed. Analysis result shows that the average deviation of the system is approximately 1°. It lays a foundation for application of eye tracking.
