3-D gaze estimation by stereo gaze direction
Wudthipong Pichitwong, Kosin Chamnongthai · 2016
The propose of this study aims to use eyeball model approach and algebra-geometric to analyze 3-D gaze estimation. Which stereo gaze directions calculate from 3-D coordinates of the value of Cornea Center and Pupil Center of left and right eyes. Then stereo gaze directions are used to get point of gaze (POG) of 3-D coordination. The experimental is designed in three conditions, (i) no head movement (ii) yaw head movement and (iii) roll head movement. The results from simulation of 3-D gaze estimation show POG accuracy.
