An armband that'll replace your computer mouse

Using super-futuristic tech to grant you "magical" power over computers, smartphones, and other nerd machines, MYO's an armband that measures the shifting electricity in forearm muscles, and can be programmed to translate movements like a flick of the wrist or a finger snap into everything from volume control, to page scrolling, to any other task that'd require much less energy to complete using a regular old mouse.The band's equipped with a rechargeable lithium ion battery, communicates with devices over "low energy" Bluetooth 4.0, and, unlike Kinect, has sensors so sensitive that they register even the slightest directional movement, right down to individual fingers.
