Controlling a human being with a game controller: it seems crazy, right? You're not dreaming: just two electrodes and a small device can help you take control of the balance of your worst enemies!
The GĂ©nialissime Vecteur de Sensations (GVS) is a Galvanic Vestibular Stimulation device built with analog electronics, designed to induce balance and orientation sensations through controlled current stimulation.
Caution
This device can deliver electrical current to a human skull. By using this project, you agree that you are solely responsible for any accident, dizziness, nausea, or existential crises that may occur. I'm not a doctor: do not use it if you don't know what you're building and doing. Max current is hardware-limited to 5mA, but that's still enough to ruin your afternoon.
Build and use it at your own risk.
Check out the detailed documentation.
Galvanic Vestibular Stimulation (GVS) is the process of sending electric messages (in this project, a low-level DC current) to a nerve in the vestibular system, located in the ear, that maintains balance. We "access" the vestibular system through the mastoid process, a conical projection forming a bony prominence behind and below the ear.
The vestibular system is a sensory organ, constitutive of the inner ear, that creates the sense of balance and spatial orientation for the function of coordinating movement with balance. This organ is present in most mammals.
Troubles of the vestibular system can lead to dizziness: this device exploits this by applying a controlled DC current to the mastoid process, artificially triggering the vestibular nerve and inducing balance and orientation sensations.
