Abstract

A simplified 3D gaze tracking technology with stereo vision has been developed in this paper. A pair of stereo cameras and two point light sources are used to estimate 3D gaze of user's eye. Compared with other 3D systems, there are two improvements to simplify the whole system in this paper: First, 3D gaze is estimated as the line linking 3D cornea center and the virtual image of pupil center using the first Purkinje images of two LEDs, and no any user-dependent parameters are used in our paper, which require a complicated calibration procedure for each user. Second, to compute the gaze point on screen by intersecting the estimated 3D gaze, the positions of LEDs and the monitor need to be calibrated in advance. By introducing a planar mirror, two LEDs and the monitor are calibrated using a simple method without any other devices. Experimental results show that our gaze tracking system achieves an average estimation error of about 3 degree.
