Hand gestures via the wide-angle camera

The wide-angle camera could enable hand gesture control, though Bloomberg's Gurman is skeptical, saying the first version likely won't have sophisticated gestures.

Apple's rumored glasses reportedly carry two cameras with split jobs: a high-res one for photos and video, and a lower-res wide-angle lens that reads your hand gestures. Instead of tapping a button or talking to the air, you'd wave or point and the glasses would follow. That wide-angle lens doubles as Siri's eyes, so it can see what you're looking at when you ask a question.
