Controlling the speed of a toy car on a Polistil racing track.

The amplitude of the EMG detected with an electrode pair on a muscle (biceps brachii in this case) controls the speed of a toy car on a Polistil racing track. Two players control two cars and (re-)learn fine and smooth control of the muscle to keep their car on track and win the game.
