Check out the latest IEEE Computer Graphics journal. They have articles in there about creating rooms with one entire wall acting as a single huge display. The wall is partially translucent and is illuminated from the rear using multiple hi-res projectors. They are carefully aligned so that the seams are invisible and careful color matching and calibration is performed. They even have a picture of GLQuake running on the wall display!
There are new multigrid reconstruction algorithms that are considerably faster than the standard huge matrix mulitiplication that is most often used. DSP boards can do the job no problem.
One possible way would be to have glasses made of a lcd crystal that can apply a phase delay to the light passing through. The problem is that you need to know where each eyeball is pointing so that you know where on the glasses to apply the correction. This implies some sort of eyeball tracking system. If you are looking straight ahead, the glasses would have to put a special phase aberration in the center of the glasses, but as your eye moves around, this phase aberration would have to shift to track where you are looking. Not really practical... Plus it would suck when your glasses ran out of batteries.
Here are some things to think about... First of all, the optical aberration of your eye is not a rapidly changing thing. The whole idea behind adaptive optics is to make rapid measurements of light propagating through a turbulent medium and compensating for this time-varying aberration in real-time. The bandwidth needed to get a decent correction through a turbulent atmosphere depends on the conditions, but is usually in the 100s of Hertz range. In the case of your eye, you do not need to have a full blown adaptive optics system. You only need to make one measurement of each eye's aberration and take the data to your local laser eye surgeon and tell him, "Here Doc, this is the wavefront measurement of my eyes. Please ablate material from my eye according to fix the aberration." No AO system is needed, just a wavefront sensor at the Doctor's office to measure how crappy your eyes are and then a good surgeon with a well calibrated laser!
