MYO is an armband that senses electrical activity in your arm and converts motions into actions on-screen. It supports wireless interaction with computers and phones. Imagine combining this with Google Glass!
The MYO is available for pre-order at $149, the possible hacks this could inspire are great. Imagine playing a virtual piano in mid-air or moving units on a battlefield with simple gestures. Two could be used, one on each arm, for Rock Band instruments: guitar, drums and bass. What other interesting uses can you think of? [getmyo]
