“There is this magic number of 240Hz that we have found through over ten years of research,” says Villwock, “at this rate you can start measuring saccadic eye movements, that is very important.”
For those of you who aren’t jumping for joy already, foveated rendering is a big deal for virtual reality because it could enable us to create realistically rendered experiences using today’s GPU and CPU technology. Foveated rendering takes advantage of human vision to cut down on what actually needs to be rendered to the screen. When you look at an object only the center of your focus, where your eye’s fovea is, appears perfectly clear with the image getting progressively less so as it approaches your peripheral.
“My personal belief is that all version two [2nd generation] headsets will have eye tracking integrated,” Villwock told UploadVR.
