The smartglass biggest problem is space constraint. The only way to have decent computation is hooking a giant computer on your face(Apple vision), with a battery in your pocket(unless you want neck pain). And even with all of that, battery life still suck.
Honestly i feel that problem is much harder to solve than hooking a bunch of projector in your home.
