Brain Interface to Twitter

There is no sound, just watch the monitor screen, you can see the letters coming up, due to brain activity.

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.

More on these developments at Department of Biomedical Engineering at the University of Wisconsin-Madison.
