Abstract: Various implementations disclosed herein include devices, systems, and methods that determine a gaze behavior state to identify gaze shifting events, gaze holding events, and loss events of a user based on physiological data. For example, an example process may include obtaining eye data associated with a gaze during a first period of time (e.g., eye position and velocity, interpupillary distance, pupil diameters, etc.). The process may further include obtaining head data associated with the gaze during the first period of time (e.g., head position and velocity). The process may further include determining a first gaze behavior state during the first period of time to identify gaze shifting events, gaze holding events, and loss events (e.g., one or more gaze and head pose characteristics may be determined, aggregated, and used to classify the user's eye movement state using machine learning techniques).

Abstract: An electronic device may have a foveated display, an eye-tracking system and a head movement detection system. The eye-tracking system may gather information on a user's point of regard on the display while the head movement detection system may capture information regarding the rotation of the observer's head. Based on the point-of-regard information, head rotation information, image data, the type of eye/head movement that is underway, and/or tiredness information, control circuitry in the electronic device may produce image data for a display, with areas of different resolutions and(or) visual quality. A full-resolution and(or) quality portion of the image may overlap the point of regard. One or more lower resolution portions of the image may surround the full-resolution portion. The control circuitry may include a gaze prediction system for predicting the movement of the user's gaze during a saccade.
