Myo is a smart armband that lets you control other devices with the swing of an arm. They say it is compatible with Windows and MacOS, with APIs available for Android and iOS. It is the first wearable interface, meaning it is always available, and can be used in mobile applications. This could be disruptive for phones’ current gyroscopes or other IR and camera features that detect motion. The creators of Myo claim that this device will make interacting with digital devices more seamless in the future.
