Abstract
Systems, methods, and computer programs for efficient use of head-mounted cameras in eye tracking. In one embodiment, a system includes a head-mounted device that takes measurements indicative of positions of an eye of a user, and a head-mounted camera that captures images of the eye. A first range of eye positions trackable from the images is narrower than a second range of eye positions trackable from the measurements. A computer calculates the eye positions based on the measurements. When the eye positions fall within the first range, the computer reads images at a first bitrate from the head-mounted camera. And when the eye positions fall outside the first range, the computer refrains from reading images from the head-mounted camera, or reads the images from the head-mounted camera at a second bitrate that is less than half the first bitrate.
