| Abstract: | We present the general structure and software design of a real-time eye-gaze tracking system based on pupil-cornea reflection vector method. First,constitution of the system equipment was introduced briefly. Then,realization of the algorithms used in the software was described in details,including cornea reflection detection,pupil center extraction and calibration. The software prototype was developed using VC + + 6. 0 and OpenCV. Experimental results show that the system is robust,and its real-time tracing... |
