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 based on a retinal imaging technique that corrects for misalignment between content display components and tracking components. In some implementations, misalignment is detected by providing a light pattern (e.g., IR light sources embedded in a display) within or adjacent to displayed content and assessing the image of the light pattern on the retina.
