  • Patent number: 11563513
    Abstract: Described herein are, among other things, techniques, devices, and systems for streaming pixel data from a host computer to a wireless display device with low latency. In some embodiments, a user mode driver is executed in user mode of the host computer to configure a wireless network interface controller of the host computer to operate in a low latency manner. The display device may use a Forward Error Correction (FEC) algorithm to reconstruct a frame from the data packets it receives from the host computer. Also disclosed are techniques for scrambling the transmission of a series of data packets using different antenna configurations, as well as setting a modulation and coding scheme (MCS) rate based at least in part on the amount of pixel data to be transmitted to the display device. The display device may comprise a head-mounted display (HMD) that renders virtual reality (VR) game imagery.

  • Publication number: 20220292790
    Abstract: This application describes a head-mounted display (HMD) for use in virtual-reality (VR) environments. The systems and methods described herein may determine information about a real-world environment surrounding the user, a location of the user within the real-world environment, and/or a pose of the user within the real-world environment. Such information may allow the HMD to display images of the real-world environment in a pass-through manner and without detracting the user from the VR environment. In some instances, the HMD may pass-through images of the real-world environment based on one or more triggering events.
