Foveated rendering is a technique to render a sharp image in the spot where a viewer is focused on a display, and fill in the periphery with low resolution.
It can reduce a rendering workload. It uses eye tracking hardware to determine at what point the user is looking and reduces rendering resolution farther from the user's gaze. This can be unnoticeable to the user because human peripheral vision has lower resolution than the fovea.[1]
It will likely be economical at very high display resolution and depth gadgets, such as holographic displays.
Foveated rendering requires eye tracking to work.
