Mental Typewriter.

Scientists from the Fraunhofer Institute and the Charité Hospital in Berlin, Germany, have created a brain-machine interface that translates brainwave signals into letters and words.

Although the current invention is still crude, it's easy to imagine that in the future, you won't have to type out your letter, just think it out! the long term, such a brain-machine interface could replace the joystick in electronic gaming or serve as a communication tool for people unable to speak or sign.

"We are dreaming of something like a baseball cap with electrodes in the cap that can measure the brainwaves," said one of the scientists behind the project, Klaus-Robert Mueller of the Fraunhofer Institute.

"People could just put on the cap and have a wireless connection from these electrodes to a computer and they can play video games."
