Abstract
Systems, methods, and computer programs for eye tracking involving a camera that is operated according to eyelid position. In one embodiment, an inward-facing head-mounted camera captures images of an eye. A head-mounted device emits electromagnetic waves towards the eye and measures reflections of these waves from the eye. The average rate of reflection measurements is at least ten times the average rate of image capture. A computer detects the position of at least one of the eyelids covering the eye based on the reflection measurements. And the camera operation is adjusted according to the eyelid position in a manner that decreases, in the captured images, areas depicting the eyelids, and optionally increases areas depicting the iris.
