Gaze detection by wide and narrow view stereo camera

Human gaze is very important information for the interaction with the computer. In this paper, we propose the new gaze detection system with a wide and a narrow view stereo camera. In order to locate the user's eye position accurately, the narrow-view camera has the functionalities of auto P/T/Z/F based on the detected 3D eye positions from the wide view camera. In addition, we use the IR-LED illuminators for wide and narrow view camera, which can ease the detecting of facial features, pupil and iris position. The eye gaze position on a monitor is computed by a multi-layered perceptron with a limited logarithm function. Experimental results show that the gaze detection error between the computed positions and the real ones is about 2.89 cm of RMS error.
