but This allows you to make a wearable controller that can read muscle activity.

The controller consists of two pairs of electrodes and the electrode of the bracelet. First attached to the biceps and triceps, and the latter worn on the forearm. The controller does not need to be calibrated separately for each user.

The electrodes measure the electrical potential arising from the excitation of the muscle cells. Thus he can control the drone four types of gestures. For example, in order for the drone to move forward, you need to make a fist. To stop to strain the shoulder muscles. To specify the direction of the drone to rotate the knuckle in the desired direction. The system uses the neural network which detects the slopes of the fist to the side.

During testing, the drone reacted correctly 81.6% of the gestures.
