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: A multiview autostereoscopic display includes a display area including an array of angular pixels, an eye tracker, and a processing system. Each angular pixel emits color that varies across a field of view of that angular pixel. The array of angular pixels displays different views in different viewing zones across the field of view of the display. The eye tracker detects the presence of the eyes of at least one viewer within specific viewing zones and produces eye tracking information including locations of the detected eyes within the specific viewing zones. The processing system renders a specific view for each detected eye based upon the location of the detected eye within the viewing zone with detected eyes, and generates control information for the array of angular pixels to cause the specific view for each detected eye to be displayed in the viewing zone in which that eye was detected.
