In same spirit of Kinect and other movement detectors, the Canadian firm Thalmic Labs recently presented Myo, a high-tech armband able to interpret musclular contractions. Myo changes your hand into a computer mouse: Raise your hand and make the web page change, or remotely manipulate a robot or drone. The device turns the world into a giant touch-sensitive screen, without actually needing to touch anything.
Myo might seem like magic, but it uses an old technology that has been used in electromyography to control the muscle and nerve activity in patients. In addition to a basic Bluetooth connection, this technology allows Myo to foresee arm movements by a tiny fraction of a second. This amazing device will be available by the end of the year for a quite reasonable price – around $115. So, if you want to feel like the mutant Magneto, it's already possible!
