A Flexible Gaze Detection Method Using Single PTZ Camera

In a past eye-gaze detection systems, users must attach a camera on the head or keep still in front of camera, to obtain zoomed image of their eye region. In this paper, we propose a flexible gaze detection method using single PTZ (Pan-Tilt-Zoom) camera. In this method, PTZ camera traces user’s face and measures position of their viewing point, so they do not need to fix their head in front of camera. In this paper, we also adapt to variation of facial orientations, which will affect to viewing position detection and gaze direction detection. After several experiments, we examine accuracy of gazing point detection and head tracking ability of this system.
