Abstract

Exact calibration in real time is critical for gaze control systems. Usually measurements are mapped to points on screen using coefficients obtained from calibration data. The mathematical model of pupil centre/ eye corner gaze tracking system was proposed. 6 parameters were used to describe both eyes movement on image sensor. Experimental results show good correspondence with model over all screen area. As some parameters are user specific and other can be measured independently, the number of calibration points could be reduced drastically, keeping nonlinear mapping.
