Abstract: A system for implementing an augmented reality (AR)/virtual reality (VR) display includes a hardware (HW) architecture that employs a system-on-chip (SoC) to compose and submit textures. The SoC composes and submits textures by using display serial interface (DSI) display lines to transmit the textures to a physical display. Software (SW) architecture includes a stack display architecture with an applications level using the surface rendered by applications, a display service level to compose superframes, provide an abstraction layer on top of a surface flinger (SL) application programming interface (API), and allow assignment of textures and metadata to different hardware planes, and a driver level. The system uses the surfaces or enhanced effects that are rendered by the applications or the compositor, depending on the type of the application, and computes the metadata related to the location or coordinates.

Abstract: A virtual object system can coordinate interactions between multiple virtual objects in an artificial reality environment. Embodiments receive a first virtual object, the first virtual object including first properties, where the artificial reality environment is set in a real-world environment. Embodiments register the first properties of the first virtual object to receive notifications of events from the artificial reality environment. Embodiments receive one or more queries from a second virtual object and in response to the one or more queries, respond to the second virtual object with identified features of the real-world environment in which the artificial reality environment is set and identifications of one or more other virtual objects (e.g., the first virtual object). The second virtual object can use the identification of the first virtual object to register for events related to the first virtual object and/or communicate with the first virtual object.

Abstract: A wrist-pose isolation system can infer a wrist pose (e.g., the user's hand position relative to her forearm) and can reduce wrist-induced jitter for projection casting in an XR environment. A user's projection cast can be determined as a combination of a “low-wrist contribution” component (e.g., a body-and-arm component) and a “high-wrist contribution” component (e.g., the pose of the wrist with respect to the arm). Using input from a gesture-tracking system, the contribution of the user's wrist pose to the user's current projection cast is calculated as a “wrist-contribution vector.” A projection cast direction can be determined as the interpolation of the current low-wrist contribution component and the high-wrist contribution component. This interpolation can be performed by weighting each by a specified amount and combining them.

Abstract: A near-eye display has an image projector coupled to a lightguide for receiving and propagating image light provided by the image projector, the image light carrying an image to be displayed to a viewer. Field of view of the near-eye display may be expanded by providing a beam redirector downstream of the lightguide for controllably redirecting the image light in coordination with displaying different field of view portions by the image projector. To compensate the redirection of external light by the beam redirector, a second beam redirector may be provided upstream of the first redirector and the lightguide.
