Generally speaking, the cameras that come built in to today's mobiles are less than astounding, but a recent Sony Ericsson patent application could make 'em a bit more worthwhile. The patent describes a scenario where a user could input commands by simply gesturing in front of the lens, and the phone would then be able to decode certain actions and react accordingly. Apparently, one could answer a phone (in handsfree fashion, of course) from across the room with just a flick of the wrist, and tracks streaming over Bluetooth could be controlled by waving your hands like you just don't care. Granted, users would still have to be where the handset could see them, but aside from that, the idea's not too shabby.
