Title: FOVEATED VIDEO LINK FOR VR, LOW LATENCY WIRELESS HMD VIDEO STREAMING WITH GAZE TRACKING
Abstract:
Gaze tracking data is analyzed to determine one or more regions of interest within an image of a video stream. The video stream data is selectively scaled so that sections within the regions of interest maintain high resolution while areas not within the region of interest are down-scaled to reduce bandwidth cost of transmission. A scheme for reduction of motion sickness by reducing the size of the high resolution area is also claimed.
