Myo is worn on the forearm and it works by using a biosensor to pick u,tp minute electrical impulses in the user's arm muscles. This gives the user the ability to wirelessly control and interact with computers and other digital consumer products around by using simple, intuitive movements such as moving their wrist, tapping their fingers together or making a fist. Myo also includes an accelerometer, a gyroscope and a magnetometer, which allows arm and body movements to be accounted for as well.
