  • Patent number: 11119568
    Abstract: In general, this disclosure describes a suspend mode feature for artificial reality systems and, more specifically, system configurations and techniques for generating a suspend mode environment during execution of an artificial reality application, and presenting and controlling user interface (UI) elements within the suspend mode environment. The suspend mode feature enables a user interacting with one or more other users (or one or more avatars corresponding to the one or more other users) within an artificial reality (AR) environment to suspend the AR environment from the user's perspective. While in the suspend mode environment, the user is able to view and select the other users from the AR environment. For example, the user may select another user to friend, message, mute, block, or report that user from the suspend mode environment.

  • Patent number: 11122385
    Abstract: Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location.

  • Patent number: 11119343
    Abstract: An optical device for providing illumination light includes an optical waveguide and a plurality of polarization selective elements. The plurality of polarization selective elements is disposed adjacent to the optical waveguide so that a respective polarization selective element receives light in a first direction, and redirects a first portion of the light in a second direction. A second portion, distinct from the first portion, of the light undergoes total internal reflection, thereby continuing to propagate inside the optical waveguide.

  • Patent number: 11119931
    Abstract: In one embodiment, a method includes receiving a request to create a data pipeline by an operating system executing on a computing device. The operating system allocates a shared virtual memory region for the data pipeline. The shared virtual memory region is mapped to a first virtual address space of a first process and a second virtual address space of a second process. The mapping enables the first process and the second process to share data through the shared virtual memory region. Membership information associated with the data pipeline is updated to include the first process and the second process. An access request for accessing the shared virtual memory region is received from the first process, and the access request is granted or denied based on one or more protection policies.

  • Patent number: 11114952
    Abstract: A device, such as an electroactive device, may include primary electrode and a secondary electrode overlapping at least a portion of the primary electrode. An electroactive polymer element may include a composite polymer material and is disposed between and abuts each of the primary electrode and the secondary electrode. A phase change or other deformable medium such as a liquid, a gas, or a liquid-gas mixture may be disposed as inclusions within the polymer material. The device can be actuated by the application of a voltage between the electrodes and the attendant formation of a Maxwell stress, exposing the deformable medium to a source of radiation, changing a pressure of the deformable medium, or changing a temperature of the deformable medium, e.g., about a phase transformation temperature of the phase change medium.

  • Patent number: 11113859
    Abstract: Disclosed herein includes a system, a method, and a non-transitory computer readable medium for rendering a three-dimensional (3D) model of an avatar according to an audio stream including a vocal output of a person and image data capturing a face of the person. In one aspect, phonemes of the vocal output are predicted according to the audio stream, and the predicted phonemes of the vocal output are translated into visemes. In one aspect, a plurality of blendshapes and corresponding weights are determined, according to the corresponding image data of the face, to form the 3D model of the avatar of the person. The visemes may be combined with the 3D model of the avatar to form a 3D representation of the avatar, by synchronizing the visemes with the 3D model of the avatar in time.

  • Patent number: 11113880
    Abstract: Particular embodiments described herein present a technique for mesh simplification. A computing system may receive a request to render an image of a virtual scene including a virtual object. The system may determine one or more positions of the virtual object relative to one or more of a foveal focus point or a lens, respectively. The system may determine a screen coverage size of the virtual object. The system may then determine a simplification level for the virtual object based on the determined position(s) and the screen coverage size of the virtual object. The system may generate a mesh representation of the virtual object based on the determined simplification level, where the number of polygons used in the mesh representation depends on the determined simplification level. The system may render the image of the virtual scene using at least the generated mesh representation of the virtual object.
