Novel application of a range image sensor to eye gaze estimation by using the relationship between face and eye directions

Abstract

In this study, we estimate gaze direction using the relationship between the face and eyes. The face and eyes are divided laterally and in lengthwise direction. We set up an object laterally and in lengthwise direction and measured the face angle using a Kinect sensor, which is range image sensor, when gazing at an object. The angle of the eyes is fixed at the angle of the object and grasp of the relationship between face and eyes. We calculate the gaze direction using the relation between the face and eyes. Then, the results of present experiment, if based on relationship between face and eyes, has been shown to be effective though the results of the experiment.
