REMOTE CONTROL DEVICE CONTROLS HUMANS
A special headset was placed on my cranium by my hosts during a recent demonstration at an NTT research center. It sent a very low voltage electric current from the back of my ears through my head — either from left to right or right to left, depending on which way the joystick on a remote-control was moved.
I found the experience unnerving and exhausting: I sought to step straight ahead but kept careening from side to side. Those alternating currents literally threw me off.
The technology is called galvanic vestibular stimulation — essentially, electricity messes with the delicate nerves inside the ear that help maintain balance.
