This device would know you're in the louvre, cause its got g p s. Maybe it sees somebody, does facial recognition, and knows they're in your social grafh where they on your instogram feet, and tells you in your ear their name. So that's superinteresting. This is starting to me sound like they will come with not only the smart phone, right? So a smart phone on your chest, above your heart, a minni smart phoan. And then maybe you have glasses that present stuff, or you have the projection projecting on to your hand, the lazers showing you gestures, et cetera....
