Eye-gaze estimation based on the pupil and iris without user-dependent parameters using a camera

摘要

We propose a method for eye-gaze estimation with neither user- nor environment-dependent parameters. The gaze direction is estimated based on the centers of both the pupil and the eye rotation, which are determined with visual angles estimated using feature points on the edge of the iris. The mean error was less than 1.0deg in the horizontal range of ±30deg.
