Apparently we DO need "foveation" or we would not be able to read FreeRepublic pages because we could not focus on the words on the screen. It comes from the way the eye moves to concentrate the image on the area with the most cells that can pick up detail, the fovea.
"Foveated imaging is a digital image processing technique in which the image resolution, or amount of detail, varies across the image according to one or more "fixation points." A fixation point indicates the highest resolution region of the image and corresponds to the center of the eye's retina, the fovea."
How do you like that!? We’ve all been clandestine foviationists all along and didn’t even know it.
