We can look forward to seeing Leap Motion-powered gesture control on tablets starting in late 2014. Right now, Leap makes a sensor that lets you use hand gestures to control your PC or Mac without touching anything.
Imagine being able to flick your hand or snap your fingers to control your iMac, video game, or other electronic device. This is what the MYO armband aims to bring to the market in late 2013. It essentially measures the electrical activity in your muscles to control the devices you're interacting with.
