Merlin’s remarks on Do By Friday 29 about the augmented reality demos at WWDC are right in agreeing that augmented reality isn’t all that interesting as an interaction model (not as revolutionary as keyboard/mouse and touch were) but is important in what it represents: the ability of our personal machines to be contextually aware of our environment, to do things as a result of that awareness, from suggesting routes through terrain, places to eat, warnings about upcoming trouble spots, or even remembering where you left your wallet and keys and parked e-bike. Gaming is a good test case even if just for getting a handle on the necessary raw compute power. The point about modeling a table well enough to place a simulated object on it which adjusts as you move is not the simulated object itself so much as that particular table, where it is, what’s on it and what you can extrapolate from there.
