Forget camera-based gesture controls — if you want complete control wherever you are, you need something like the Myo Gesture Control Armband ($150). This innovative new input device communicates with your Mac, PC, phone or tablet over Bluetooth 4.0, and uses proprietary muscle sensors as well as a 6-axis motion sensor to track your movement. The muscle sensors are advanced enough that it can detect changes in gestures down to the individual finger, and because your muscles pick up the signal to move before they actually do, you may see it respond to your movements before you even move. May be combined with a smartphone, Google Glass, and a jetpack to build a "Superhero Starter Pack".
