Galvanic Vestibular Stimulation

Galvanic vestibular stimulation is a method of controlling and constraining natural balance and movement ranges by using two weak electrical fields, delivered just behind the earlobes to control a person?s vestibular system, control nexus for the twin senses of movement and balance.

When a weak DC current is delivered to the mastoid behind a person?s ear, their body responds by shifting your balance toward the anode. The stronger the current, the more powerful its pull. If it is strong enough, it not only throws them off balance but alters the course of their movement.

It is possible using such a system to produce very realistic sensations of movement for cockpits and ground-based driving simulators, accurately replicating the feel of travel with little or no actual movement.

Balance in the Blood not just the Ear
Galvanic Vestibular Stimulation. For those of us familiar with it, it's a possible panacea to cure simulation sickness, and rope the sense of balance of the user directly into the simulation. Unfortunately, it seems there is a fly in the mixture.

Industry News

Industry news from August 2005, featuring the debut of 'galvanic vestibular stimulation' or GVS. GVS is a means of controlling the input sent to the body's balance centres via a pair of devices behind the ears. Capable of tilting your balance to make you think you are moving in any direction at any time, GVS offers many hopes for cheap, mass-market movement simulation.

Repairing and Virtualising Balance in one Swoop
Without the vestibular system we lose our sense of balance entirely. Balance is vital in the physical world. In the virtual, it is not yet vital, but would be handy for an increasing number of situations. What if there were ways to use prosthetics to give balance back to those without, and to then utilise that same discovery, to bring balance, into VR?

The Orgasmatron
A prosthetic device, implanted the lumbar region at the back of the spine, that functions, essentially, as an orgasm control circuit, and bypass route for sexual stimulation without actual physical sex.

A mis-fire in the teledildonics industry, this early attempt at sexual stimulation in VR fell short after it was discovered it had a minor side effect - bodily secretions caused a lethal electrical discharge.

Optics and Neuroprosthetics
A new tack in neuroprosthetic interfaces is being born out of pulses of light rather than electricity. Termed 'optogenetic neuromodulation, the technique is being pioneered in the hope that it will enable a far greater level of accuracy and single-cell stimulation than is possible with electrode interfaces.
