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 (222, 310, 610) that illuminate different portions of the user's retina (352). In some implementations, a method (700) includes selecting (710) 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 (352) are illuminated (720) by producing light using the subset of the light sources. In some implementations, sensor data is received (730) at a sensor (224, 340, 814), the sensor data corresponding to the light detected during retinal imaging, and an eye characteristic is determined (740) based on the sensor data.
