Abstract: An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity.

Abstract: A device includes a camera assembly and a controller. The camera assembly is configured to capture images of both eyes of a user. Using the captured images, the controller determines a location for each pupil of each eye of the user. The determined pupil locations and captured images are used to determine eye tracking parameters which are used to compute values of eye tracking functions. With the computed values and a model that maps the eye tracking functions to gaze depths, a gaze depth of the user is determined. An action is performed based on the determined gaze depth.

Abstract: Embodiments relate to an eye tracking system. A headset of the system includes an eye tracking sensor that captures eye tracking data indicating positions and movements of a user's eye. A controller (e.g., in the headset) of the tracking system analyzes eye tracking data from the sensors to determine eye tracking feature values of the eye during a time period. The controller determines an activity of the user during the time period based on the eye tracking feature values. The controller updates an activity history of the user with the determined activity.

Abstract: Embodiments are related to a plurality of gaze sensors embedded into a frame of a headset for detection of a gaze vector of a user wearing the headset and user's control at the headset.

By monitoring signals detected by the gaze sensors, it can be determined that the gaze vector is within the threshold distance from the gaze sensor. Based on this determination, at least one action associated with the headset is initiated.
