BCI - Brain-computer-Interfaces - are utilized usually in medical or scientific environments to give a patient or proband feedback about his brain functions. Generally, waves of the outer brain regions are used to accomplish this (like in an EEG), a simple and unexciting technique. For musicians this isn't that new, either: some years ago I've read about brain to midi converters (see German KEYBOARDS, 1994/4: p13; short mention here). Game makers want to implement this into their next games. And immediately scientists caution against possible side-effects, when a game situation that has to be mastered with a special brain curve comes to reality and the trained response used in the game might not be the best response in reality. "You could have an accident. I think it's a rare possibility, but it should be tested before people do this.", says Niels Birbaumer, a leading independent research in medical applications of BCIs.
Evil thought: would you notice any difference between feedback car drivers and normal ones, especially when it comes to slow brain waves?
