Washington, Apr 25 : Taking a revolutionary step towards modern communication technologies, a doctoral student posted a status update on the social networking Web site Twitter - only by thinking about it.
Adam Wilson's message-"using EEG to send tweet"- just 23 characters long, demonstrated a natural, manageable way in which "locked-in" patients can couple brain-computer interface technologies with modern communication tools.
Wilson, from University of Wisconsin-Madison biomedical engineering doctoral student, is among a growing group of researchers worldwide who aim to perfect a communication system for users whose bodies do not work, but whose brains function normally.
