Biomedical company Advancer Technologies has created a plug-in-play device that allows players to directly control video games with their muscles using the power of electromyography (EMG).

Using the low-cost, yet powerful Arduino UNO microcontroller, the universal serial bus (USB) Biofeedback Game Controller allows four muscles to act independently or in combination with each other to control over four buttons.

The left forearm controls the B button (run/attack), the right forearm controls the A button (jump), the left bicep controls the LEFT button, and the right bicep controls the RIGHT button, as well as combinations for UP and DOWN. During gameplay, the Arduino UNO program tracks muscle activity through sensors. A spike in activity triggers a button press, sending the information to the computer via the USB connection in real time.

Advancer Technologies is showing off the device in a new video, where a man navigates his way through the first level of Super Mario Bros. 3 using only his muscles.

The company says the controller can be used for practical applications like helping victims of neuromuscular disease or injury rehabilitate their muscles while playing video games. “[Plus] using your muscles to control computers, robots, [and] video games is fun no matter what your age,” the company says.
