Article features a brain-computer interface used to post a message on the social networking website Twitter. The interface, designed by scientists at the University of Wisconsin-Madison’s College of Engineering, is based on brain activity related to a keyboard displayed on a computer screen. Wearing an electrode-studded cap that is attached to a computer, the user types a message by concentrating on the keyboard keys which flash sequentially. The electrodes detect the electrical signals in the brain and translate them into actions such as selecting a flashing letter on the screen. The interface was developed for people with severe physical disabilities including those with spinal cord injury and locked-in syndrome. Twitter messages have a 140-character limit, a message length that, according to the inventors, is within locked-in users’ capabilities.
