22-3 Improvement of calibration method on a remote eye-gaze detection system

Abstract

We have developed a remote head-free eye-gaze detection system with easy calibration. In the calibration procedure, it was necessary for a subject to look at the center of the aperture of the narrow camera and a marker on a PC screen. However, it was difficult to look at the center of the aperture precisely because its position was not clear. In this paper, we propose two calibration methods by looking at positions other than the aperture of the camera.
