This paper proposes a method for extraction of the gaze point on screen using EOG(Electrooculography) signal. Based on linear property of horizontal and vertical EOG signal, the proposed method corrects two dimensional distance error between coordinate of using EOG signal and coordinate on screen by using scaling, rotation and transformation. Experimental results show that the average distance errors at the gaze points are 3%(57pixels) at x-axis, 9%(90pixels) at y-axis on the monitor with 1680*1050 resolution. This method can be used to human computer interface of pointing device for general paralysis patients or VR games.
