Thalmic Labs Announces MYO Gesture Control Armband

Unlike other gesture control devices that rely on positioning through camera tracking, the MYO armband senses electrical activity in the muscles that control hand and finger motions. Its worn on the forearm and flexing of various muscles serve as gesture inputs. These inputs are communicated via Bluetooth, which are then translated into motions on the screen thanks to some machine-learning algorithms.
