Mind Reading Computers
"New technology could allow people to dictate letters and search the internet simply by thinking, according to researchers at Intel who are behind a mind-reading computer project. ... Unlike current brain-controlled computers, which require users to imagine making physical movements to control a cursor on a screen, the new technology will be capable of directly interpreting words as they are thought. Intel's scientists are creating detailed maps of the activity in the brain for individual words which can then be matched against the brain activity of someone using the computer, allowing the machine to determine the word they are thinking. Preliminary tests of the system have shown that the computer can work out words by looking at similar brain patterns and looking for key differences that suggest what the word might be."
