Twitter on the Brain

Twitter has become habit-forming for many people, but only Adam Wilson can claim to have posted on Twitter using his brain waves. His message, "using EEG to send tweet," was actually a demonstration of brain-computer interface technology. Wilson, a University of Wisconsin biomedical engineering doctoral student, is interested in providing communication interfaces for people with "locked-in syndrome," meaning their brains are functional but communication is hampered by injury or a medical condition.

Wilson used an electrode-studded cap wired to a computer to send electrical signals from his brain to an on-screen keyboard. Focussing on a letter caused it to be 'typed' on the keyboard. The Twitter experiment was one of the first to tie a brain-computer interface to Internet technology. Justin Williams, a UW professor and Wilson's advisor, hopes that this demonstration will inspire other researchers to focus on inventions that will help the daily life of people with neurological deficits.
