Abstract
An eye and environment sensing system for a head-mounted device may be configured to determine changes in an eye orientation and range objects in the environment by sharing a common light source. The eye and environment sensing system includes a light source, a first photodetector, and a second photodetector. The light source is coupled to a frame of a head-mounted device and configured to provide a light beam to illuminate a portion of an eyebox region. The first photodetector is coupled to the frame and is oriented towards the eyebox region to receive reflections of the light beam from the eyebox region. The second photodetector is coupled to the frame and is oriented towards a scene side of the head-mounted device to receive reflections of the light beam from an environment of the head-mounted device. With a shared light source, battery consumption in the head-mounted device may be reduced.
