Title:
EYE TRACKING WITH PREDICTION AND LATE UPDATE TO GPU FOR FAST FOVEATED RENDERING IN HMD ENVIRONMENT
Document Type and Number:
Japanese Patent JP2023037626
Kind Code:
A
Abstract:
To predict and late-update a targeted landing points on a display such that movement of the eye(s) of a user coincides with the presentation of a foveal region on the display at the updated targeted landing point.SOLUTION: Provided is a method for updating information for a graphics pipeline including executing in a first frame period an application on a CPU to generate primitives of a scene for a first video frame. Gaze tracking information is received in a second frame period for an eye of a user. In the second frame period a landing point on an HMD display is predicted at the CPU based at least on the gaze tracking information. A late update of the predicted landing point to a buffer accessible by the GPU is performed in the second frame period. Shader operations are performed in the GPU in the second frame period to generate pixel data on the basis of the primitives and on the basis of the predicted landing point.SELECTED DRAWING: Figure 11B
