For the first time, a person with a serious muscular disorder has used brainwaves to chat and stroll through the virtual world of Second Life. The computer system uses electrodes as small as 1cm in diameter that are attached to the scalp. A computer detects brainwaves from the sensory-motor cortex when the subject slightly moves fingers of his/her right and left hand, and moves the avatar accordingly. The computer also detects the subject's will to move forward, and makes the avatar move forward.
