A US/Australian firm has invented a simple neural headset, allowing direct control of computers from the brain. It's crude - basically it does directions, as well as picking up basic emotions and facial expressions (the latter presumably through muscle signals) - but its a start. And it's cheap - they're planning to sell it for a mere US$300.
Naturally, they're aiming it at the online gaming market.
Yes, a miracle of engineering, with piles of applications (just think what it could do for the disabled, for a start), and their intended use is so your Orc can snarl realisticly while you insult your enemies in World of Warcraft.
