SAN JOSE, Calif. — A convincing twin of Darth Vader stalks the beige cubicles of a Silicon Valley office, complete with ominous black mask,
cape and light saber.
But this is no chintzy Halloween costume. It's a prototype, years in the making, of a toy that incorporates brain wave-reading technology.
Behind the mask is a sensor that touches the user's forehead and reads the brain's electrical signals, then sends them to a wireless receiver inside
the saber, which lights up when the user is concentrating.
The player maintains focus by channeling thoughts on any fixed mental image, or thinking specifically about keeping the light sword on. When the mind
wanders, the wand goes dark.
Pretty soon people are going to be playing Virtual Reality games and just using their thoughts to control the game.
Science has been advancing very fast lately.
