A human-robot interface using vision-based eye gaze estimation system

Abstract

Recently, service area has been emerging field of robotic applications. Even though assistant robots play an important role for the disabled and the elderly, they still &er from operating the robots using conventional interface devices such as joysticks or keyboards. In this paper, we suggest a humanrobot interface using a new eye gaze estimation system. The eye gaze estimation system can estimate the direction of a user’s eye gaze. The proposed system consisted of five IR LEDs and a CCD camera. The direction of the user’s eye gaze can be computed without computing the geometrical relation among the eye, the camera, and the monitor in 30 space. Our method is comparatively simple and fast. The disabled, who is especially people with motor disabilities, can control a robot using this system. We will introduce the method and show experimental results. The experimental results will verify the feasibility of the proposed system as a human-robot interface for the disabled.
