Comparison of two techniques for gaze estimation system using the direction of eyes and head

Binocular eye-gaze tracking can be used to estimate gaze of a subject in space using the vergence of the eyes. We analyze eye movement and head movement. As for the eye movement, we used the TalkEye which is eye tracking device. The head angle determined by template matching using a camera attached to TalkEye. A purpose of this study is to compare the proposal method using TalkEye with the conventional method to perform a high-precision gaze estimate. Conventional method is a method of using the Electrooculogram (EOG) signal and RGB-D sensor. Experiments were performed in both indoor and outdoor. The subjects could move eyes and a head freely in wide space. From the experiments, we show the result of 30 degrees, 60 degrees, −30 degrees, and −60 degrees gaze estimation is possible with high precision. In addition, we compared proposal technique and the conventional technique using a regression analysis and considered the effectiveness.
