Watch out, Yuri Geller. The Korea Research Institute in Taejon has hatched a
computer game in which players bend a spoon simply by thinking about it (WO
01/07128). The gamer wears a headband with electrodes that detect brain waves.
Before play, the system records the subject鈥檚 natural balance between 鈥渞elaxed
state鈥� alpha waves鈥攁t 8 to 13 hertz鈥攁nd 鈥渁ctive state鈥� beta
waves鈥攁t 13 to 30 hertz. Any change in the ratio鈥攁nd the rate of
that change鈥攊nfluences the direction and speed of a game character on
screen. When a picture of a spoon is seen on screen, relaxed, low frequencies
make it bend. Game skill improves as the player associates mental state with
on-screen action, and learns to bend the spoon by chilling out.
