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 felt a mysterious, irresistible urge to start walking to the right whenever the researcher turned the switch to the right. I was convinced -- mistakenly -- that this was the only way to maintain my balance.

The phenomenon is painless but dramatic. Your feet start to move before you know it. I could even remote-control myself by taking the switch into my own hands.
