A person's gaze doesn't stay fixed on the center of the screen; it shifts constantly.
yes, then maybe in the VR goggles of the future which are adjusting to where they sense your eyes are pointing etc. - the variable resolution part of the comment was actually meant with some humor

A random thought on the subject.
I had a very interesting conversation today with an electrical engineer
friend. Part of his current research deals with the way human (and I
suppose other animal) brains process visual information. Assuming that
his references are correct, it more or less boils down to an exercise in
data compression. My non electrical engineer understanding is that
signals from our eyes are fed to our brain. Simultaneously, the brain
creates a signal representing what it expects to see. The two signals
are compared and the visual signal is discarded except for the parts
that are different from the brain's predicted signal.absolutely - and what's more only the very center of your gaze has the highest resolution with peripheral vision being the equivalent of low rez (fewer photoreceptors) and so your brain is constantly filling in what it expects to see in the periphery - I was first struck by that idea when reading this fun book ; http://www.amazon.com/Sleights-Mind-Neuroscience-Everyday-Deceptions/dp/0805092811/perhaps someone should create a variable resolution display / file format with higher resolution in the center to save bandwidth : )
