Twitch streamer uses electrodes to manipulate balance using electricity — can be used to control a real-life human being with an Xbox controller or joystick, simulate racing game G-force

Overview

A Twitch streamer and creator demonstrated a potentially dangerous balance “hack” by attaching electrodes behind her ears to pass a current through her head. The sensation, known as galvanic vestibular stimulation (GVS), uses electrical signals to affect a person’s balance. In theory, it can be used to simulate G‑force in racing games or, more controversially, to control the direction and movements of a real‑life human being with a joystick or Xbox controller.

Safety Warning

“Don’t do this. Don’t build this. Don’t make this. I do not approve of anyone making this themselves,” the creator said in her Instagram video. “I don’t condone that behavior; it’s incredibly dangerous and I’m not liable!”

It goes without saying that you should not try this at home.

Prior Use in Gaming

This isn’t the first time a GVS device has been used with a game. A 2021 Reddit post shows user u/yahma driving with the electrodes attached to his head. He would lean toward the direction the in‑game car turned, and when the car tumbled off the track, the Redditor also fell out of his seat.

Scientific Background

Doctors and scientists have been studying GVS since the 1990s, though it is not yet widely used in routine medical treatment. Some clinical studies are exploring its potential for treating balance‑related conditions and other therapeutic applications. However, the long‑term effects of applying GVS to the head remain unknown, reinforcing the creator’s warning against DIY attempts.
