Something like this would be the key breakthrough. For all all their versatility the human eyes have not evolved to be (have not been designed for - depending on your viewpoint :) an optical interface for digital systems. Most of the hard work at the moment is in working around the "limitations" of our visual pipeline. Rudimentary technology that does just this has been around for a while as assistive devices for blind people [0] albeit only rudimentary shapes and movement can be portrayed. I believe ultimately the most effective technology will be that which integrates directly with the visual cortex, which I read somewhere has neurons arranged somewhat isomorphically with the visual field [1] I think this should be sufficient to stimulate both higher cognitive and the more reflexive automatic visual systems [2] though IANAN and really haven't look at this area in depth for a number of years. To get into the realms of pure science fiction about it [3], this could even be done by way of the pineal gland, which has some optical features that are largely unused. Perhaps it was put there like that for a reason ... [0] http://www.fightingblindness.ie/cure/retinal-implant-technology/ http://www.fightingblindness.ie/cure/retinal-implant-technol...
