Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling.

Abstract: Systems and methods for providing assistance for manipulating objects using virtual proxies and virtual replicas are provided. Disclosed systems enable a remote or co-located subject matter expert (SME) to provide guidance to a local user on how to manipulate physical or virtual objects in the local user's environment. The local user views an augmented reality (AR) display of the local environment. The SME views a virtual reality (VR) or AR display of the local environment. The SME manipulates virtual proxies and virtual replicas to demonstrate to the local user how physical or virtual objects in the local environment should be manipulated. In other scenarios, a local user is provided instruction by using a display from which the local user can view the local environment. Manipulations of objects are tracked and the system provides the user feedback on whether the objects are properly oriented.
