What are some parameters of foveated human vision?
The resolution at the center of the retina is about 1 arcminute under ideal conditions, and this falls off rapidly outside the central 2 degree region. At 10 degrees eccentricity, the resolution is about 10 arcminute. A high resolution display with 1280 pixels across a 60 degree field of view achieves about 3 arcminutes per pixel. This means that outside the foveal region, much of the screen resolution is wasted.
