Abstract
Systems and methods for performing eye tracking using a scanning light signal with low power consumption are disclosed herein. Power consumption is reduced by intelligent disabling and re-enabling of non-imaging photodetector(s) and/or light source(s). In one embodiment, the scan region is contracted to a single feature of the eye (e.g., the pupil, a glint, etc.) in view of a particular type of event of interest to detect.
