Non-Invasive Computer Control Through Brainwaves
mikael writes "An article on the BBC website is reporting that U.S. scientists have managed to develop a 'thinking cap' which allows a computer to receive commands from the electrical activity of a person's brain alone. Comprised of 64 electrodes, this cap allowed two users to control a cursor through pure thought alone, rather than through eye movements or other physical gestures." Unlike some previous efforts, this one doesn't require anything to be implanted in your brain.
At the WorldExpo 2000 in Hannover/Germany, the Swedish booth showed something similar. Two contestants were wearing tin foil hats that measured their brain activity. The higher the brain activity, the lower the score, so the goal was to be more relaxed than the opponent.
The great thing was that the most ambitious people had no chance, because their brain was too active in wanting the victory. Pretty cool, watching two guys relaxing the hell out of each other.
