ABSTRACT

       An eye-tracking device by using linear image sensor to determine the eye's gazing direction. This linear image sensor mounted below the user's eye, or mounted on the HMD (head mounted display), continuously observes the user's eye. A DSP unit receives the one-dimensional eye's image signal and interprets the pixel data to a gaze point of regard of the user on an interface device. From the quatity of dark pixels we can obtain the vertical angle of gaze direction and from the location of dark pixels we can also obtain the horizon angle of gaze direction. Then DSP unit provides accurately tracking the user's eye movements for the computer and performs a new rapid user interface.
