Adam Wilson posted two messages on Twitter on April 15. The first one, “GO BADGERS,” might have been sent by any University of Wisconsin-Madison student cheering for the school team. His second post, 20 minutes later, was a little more unusual: “SPELLING WITH MY BRAIN.”
Wilson, a doctoral student in biomedical engineering, was confirming an announcement he had made two weeks earlier — his lab had developed a way to post messages on Twitter using electrical impulses generated by thought. That’s right, no keyboards, just a red cap fitted with electrodes that monitor brain activity, hooked up to a computer flashing letters on a screen. Wilson sent the messages by concentrating on the letters he wanted to “type,” then focusing on the word “twit” at the bottom of the screen to post the message.
The development could be a lifeline for people with “locked-in syndrome” — whose brains function normally but who cannot speak or move because of injury or disease.Read the rest here.
