Abstract
Various implementations disclosed herein include devices, systems, and methods that provide retinal imaging-based gaze tracking In some implementations, a user's gaze is tracked based on a retinal imaging technique that selectively uses a subset of multiple light sources () that illuminate different portions of the user's retina (). In some implementations, a method () includes selecting () a subset of light sources, where the subset of the light sources includes less than all of the light sources. In some implementations, one or more portions of a retina () are illuminated () by producing light using the subset of the light sources. In some implementations, sensor data is received () at a sensor (), the sensor data corresponding to the light detected during retinal imaging, and an eye characteristic is determined () based on the sensor data.
