Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

Abstract: Conventionally, applications are updated to the current version and the previous version is removed, eliminating backward compatibility. The disclosed technology provides XR runtimes that can dynamically execute a runtime version due to the runtimes being executed as a collection of selectable data bundles. Thus, implementations can ship multiple versions of an XR runtime to allow old versions of the XR runtime to remain when updates occur. Implementations can maintain backward compatibility and allow old experiences to run in an application. Implementations can access metadata associated with an experience to determine what runtime version (or set of runtime versions) under which the experience can execute, and can dynamically run the latest runtime version that can support that experience. When multiple users in a group are joining an experience, implementations can select and run a common server-supported runtime and push any necessary data bundles for the experience to the client devices.

Abstract: Described herein are techniques and technologies to identify an encrypted content within a field of view of a user of a VR/AR system and process the encrypted content appropriately. The user of the VR/AR technology may have protected content in a field of view of the user. Encrypted content is mapped to one or more protected surfaces on a display device. Contents mapped to a protected surface may be rendered on the display device but prevented from being replicated from the display device.

Abstract: Methods and systems are provided for a reprojection engine for augmented-reality devices. The augmented-reality device projects virtual content within a real-world environment. The augmented-reality device tracks a six degrees of freedom headpose of the augmented-reality device, depth information of the virtual content, motion vectors that correspond to movement of the virtual content, and a color buffer for a reprojection engine. The reprojection engine generates a reprojection of the virtual content defined by an extrapolation of a first frame using the headpose, the depth information, motion vectors, and the color surface data structure. The reprojected virtual content continues to appear as if positioned with the real-world environment regardless of changes in the headpose of the augmented-reality device or motion of the virtual content.
