Boffin gives Twitter a piece of his mind
By Davey Winder in Editorial
I’m not usually one to recommend watching online video clips but this one is a real cracker. It shows a biomedical engineering student at the University of Wisconsin-Madison apparently posting to Twitter using his brain.
OK, that in itself is something to celebrate given the quality of some Twitter postings which suggest no brain cells were wasted in writing them. However, the message “using EEG to send tweet” was, we are assured, composed and posted using nothing more than the power of thought and an interface between the brain of the researcher and the computer in question.
Aimed at helping those who suffer from ‘locked in syndrome’ where the body has failed but the brain is working properly, such as can happen following a brain stem stroke or a spinal cord injury, the system uses an electrode studded cap which picks up the electrical signals from the brain and map them to pshysical movement on the computer screen.
Wilson says that with practise he has “seen people do up to eight characters per minute” using the power of thought alone. Justin Williams, an assistant professor working with Wilson added “This is one of the first examples where we’ve found something that would be immediately useful to a much larger community of people with neurological deficits.”
