http://www.emotiv.com/2_0/2_1.htm Meet Project Epoc.... a headset that uses a set of sensors to tune into electric signals naturally produced by the brain to detect player thoughts, feelings and expression. It connects wirelessly with all game platforms from consoles to PCs. Project Epoc now makes it possible for games to be controlled and influenced by the player's mind.
The problem with such a device is that things never work as well in real life as they do in people's living rooms. Just look at the motion sensing in today's console controllers, or the eye toy for the PS2. Each works pretty well, but not perfectly. There are still occasional setup issues, misinterpretation of gestures, etc. The same is most likely true for this device. I take psychology and I know that when placing electrodes to measure brain waves, the ideal method is to shave the area, if necessary, remove any makeup, rub with alcohol, then tape the sensor on. In fact, it's even better if you can insert the electrodes directly into the brain. Clearly these methods are incredibly inconvenient, and although there are compromises that can be made, they all decrease the quality of the data which the machine creates. Multiple electrodes implanted in a paralysed man enabled him to control a cursor, but only with extensive training and great difficulty. The system was functional, but it's gonna be a long way before the average gamer controls their character's movements with their mind.
