This project is an experiment on gaze tracker system, based on the position of glint on the iris, which is the reflection of a source of light located near the camera (See Purkinje images and Eye tracking for details). By tracking the glint it is possible to estimate the gaze position on the screen and use this position as an input system (in this example it is used only to move the mouse arrow).
For this kind of system, an high resolution image of the eye is required and a source of light near the camera too, so to get that with simple hardware I use a smartphone as a remote camera (achieved by IP Webcam app) fixed on a stable support, turn on the flash LED and put it in front on one eye, close to it.
