"It probably has to or the info overload would be debilitating." In a sense. To give the high resolution field of view our visual systems appears to give would require a lot more bandwidth than is actually available. You'd have to have an optic nerve the size of your eyeball, and that still wouldn't do it. So the eye, the optic nerve and the brain all operate together to make it appear that is what you are seeing. You only have the resolution your eye appears to have in the center where the fovea is. Well, at the exact center is where the optic nerve is and there is the blind spot there. To make it worse, if you could keep your eye from moving, the image would fade out as the retina fatigues. So your eye is constantly moving in a jerky fashion, jumps, stops briefly, jumps again, called saccades. And the focus is always moving around, following contours, being attracted by motion, etc. So when you think you are staring at something with a fixed gaze, you aren't. The 1/10th second delay is because nerve signals are chemical in natural and propagate very slowly. Given how everything you see is a construct, it isn't a big leap to add in the projection. Interesting to see that someone can actually prove it is happening. And, yet another nail in the eye witness coffin. Because the brain not only fakes much of what you see in a more or less static image, it also can fake quite a bit when it is trying to interpret actions.
