I love this…and I think we're going to get to "gesture fatigue" pretty quickly here. We all had to learn a whole bunch of new things when smartphones (and the iPhone in particular) came out … "pinch-to-zoom" and the like. And now OS X Lion is introducing a whole new set of gesture-based interface items. Now on the horizon are "bending" gestures and such.
Ok, it all looked cool in the movies when Tom Cruise did this kind of stuff the first time. And it does make new capabilities easily accessible, if you know all the gestures. So, what about you…does this Cambrian explosion of interface capabilities make things easier for you to interact with your devices, and the world? Or does it make things overly complex?
