Abstract
A miniature eye tracking system is disclosed that includes a camera, a microelectromechanical (MEMS) device, and a processor. The camera images an eye. The MEMS device controls the view-direction of the camera. The processor receives an image of the eye from the camera, determines the location of the eye within the camera image, and controls the MEMS to keep the camera pointed at the eye. In another embodiment, the MEMS device controls an adjustable focus of the camera. The processor determines the focus condition of the eye image, and controls the MEMS device to maintain a desired focus condition of the camera on the eye. In another embodiment, the MEMS device controls an adjustable camera zoom. The processor determines the size of the eye image within the overall camera image, and controls the MEMS to maintain a desired size of the eye image within the overall camera image.
