Abstract: Identifying a specular surface, such as a mirror, in a captured scene includes extracting, from one or more images of the scene, a set of natural features and generating, from the image, a set of synthesized “mirrored” features. One or more correspondences may be determined between the set of natural features in the image and the set of synthesized mirrored features. A first set of features are identified based on the determined one or more correspondences as representing a specular surface (e.g., a mirror) located in the scene, and then a geometry and/or location of the specular surface within the scene may be determined. For example, in some embodiments, the feature from a determined pair of corresponding features in a scene that is determined to be farther away from the device that captured the image(s) of the scene may be determined to be the feature lying on the specular surface.

Abstract: Various implementations disclosed herein include devices, systems, and methods that use a marking on a transparent surface (e.g., a prescription lens insert for an HMD) to identify information (e.g., prescription parameters) about the transparent surface. In some implementations, the markings do not interfere with eye tracking through the transparent surface or using the transparent surface to view virtual content or a physical environment. In some implementations, image data is obtained from an image sensor of an electronic device, the image data corresponding to a transparent surface attached to the electronic device. Then, a code is identified in the image data, wherein the code is detectable on the transparent surface by the image sensor without interfering with a function of the electronic device involving the transparent surface. In some implementations, content is provided at the electronic device based on the identified code, wherein the content is viewable through the transparent surface.

Abstract: A VR system for vehicles that may implement methods that address problems with vehicles in motion that may result in motion sickness for passengers. The VR system may provide virtual views that match visual cues with the physical motions that a passenger experiences. The VR system may provide immersive VR experiences by replacing the view of the real world with virtual environments. Active vehicle systems and/or vehicle control systems may be integrated with the VR system to provide physical effects with the virtual experiences. The virtual environments may be altered to accommodate a passenger upon determining that the passenger is prone to or is exhibiting signs of motion sickness.

Abstract: Various implementations disclosed herein include devices, systems, and methods that render a reflective surface of a computer-generated reality (“CGR”) object based on synthesis in a CGR environment. In order to render a reflective surface of the CGR object, one exemplary implementation involves synthesizing an environment map of a CGR environment representing a portion of a physical scene based on observed characteristics of the physical scene. In an implementation, generation of a complete environment map includes identifying pixels of the environment map with no corresponding texture and generating synthesized texture based on textural information associated with one or more camera images of the physical scene. In an implementation, a CGR object is rendered in the CGR environment, wherein an appearance of a reflective surface of the CGR object is determined based on the complete environment map of the CGR environment.
