Abstract: An eye tracking system with in-optical-assembly plane illumination is described. Side-emitting light emitting diodes (LEDs) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. A waveguide display of the near-eye display device projects computer-generated content to the eye. A mirror is positioned between the LEDs and the waveguide display to reflect light beams generated from the LEDs toward the waveguide display to mitigate any double glints that may cause ghost signals. A processor of the near-eye display device determines a position and gaze of the eye based on the captured image of the eye with the glints, and generates the computer-generated content for the waveguide display based on the position and gaze of the eye.

Abstract: An audio system determines latency for each client device of users participating in an artificial reality or augmented reality environment. The latency determined for a client device accounts for latency of a communication channel used by the client device to exchange data, as well as time for the client device to perform computational tasks. The audio system determines a distance in the artificial reality environment between a user's avatar and an audio source for audio data and adjusts one or more transfer functions for generating audio content for the user to account for effects of the latency determined for the user's client device on the audio content. In some embodiments, the audio system modifies a distance in the artificial reality environment between the user's avatar and the audio source to compensate for latency of the user's client device.

Abstract: Information relating to gaze direction is used, e.g., with other information, to perform tone mapping, brightness adaptation, and/or sparkle generation/management for virtual or augmented reality displays. For example, speed of light adaptation may be increased as a user's gaze moves from a darker scene to a brighter scene and decreased in opposite direction to match human perception dynamics in real world. Sparkles from smaller objects may be adjusted depending on an object size, a brightness of the object's background, and/or the object's location relative to the user's gaze—that is, whether the object in the user's focus or in a periphery. Specularity of the objects may be obtained from a specularity map (e.g., metadata associated with each object) or from image processing a scene. Local sparkles may be shimmered as the user's head rotates deterministically or randomly to provide a sense of real-life glistening.
