Abstract
Current eye tracker is able to estimate with high precision using eye image. This method need to get high-quality image of eye, therefor it cannot estimate using low quality eye images which has low resolution, illumination change and occlusion. Other method is using pose information including the head direction, the body direction, and the head motion. This method gets pose information using Eigen space method Therefor it must need calibration phase. In addition, the eye direction using this method is only horizontal. We propose a gaze estimation algorithm without high quality images of eye. The purpose is estimation not using eye image, and error is 10 degrees below. Experimental result show that the method can estimate gaze direction not using image of eye.
