HIDING LATENCY IN WIRELESS VIRTUAL AND AUGMENTED REALITY SYSTEMS

机译:隐藏无线虚拟和增强现实系统的延迟

摘要

Systems, apparatuses, and methods for hiding latency for wireless virtual reality (VR) and augmented reality (AR) applications are disclosed. A wireless VR or AR system includes a transmitter rendering, encoding, and sending video frames to a receiver coupled to a head-mounted display (HMD). In one scenario, the receiver measures a total latency required for the system to render a frame and prepare the frame for display. The receiver predicts a future head pose of a user based on the total latency. Next, a rendering unit at the transmitter renders, based on the predicted future head pose, a new frame with a rendered field of view (FOV) larger than a FOV of the headset. The receiver rotates the new frame by an amount determined by the difference between the actual head pose and the predicted future head pose to generate a rotated version of the new frame for display.
