Gaze tracking system for teleoperation

Abstract

Conventional control interfaces such as joystick, keyboard, and mouse are widely used in teleoperation. However, they are not operated by some users such as who have disabled hands. This paper proposed an eye gaze tracking system for teleoperation. The eye gaze tracking system is based on non-intrusive, visible light, iris center corneal reflection (ICCR) and 2-D mapping-based gaze estimation. In addition, this paper also presented a simple and effective 2-D mapping-based calibration method in order to users with head movement. The calibration verification of five users shows the average errors of our proposed gaze tracker on the x- and y directions are 13.3 and 16.4 pixels, respectively. Through the teleoperation test of robotic car within fixed experimental area, the gaze tracking system achieved a good control result.
