| Abstract: | In this paper a novel design which combines an eye-tracking device with a head gesture control module is discussed. In the eye-tracking mode, the user wears goggles, and two tiny CCD cameras capture the eye image from the screen with the help of a video capture card. In the head gesture control mode, a light source projector is turned on, and the CCD camera detects the position of the light source. The locations of the spots on the screen and on the image pupil of the eye image are calculated, compared with the previous point and are subsequently mapped to the point on the screen. The movement increment-coordinate control is also discussed, which could improve the ease of use of the computer. |
