An anonymous reader writes "How about typing on a computer just by thinking about it? The downside is you have to wear a skull cap with electrodes that capture your brain waves like an EEG machine. According to this EE Times story, a team of researchers from Belgium and the Netherlands has presented Mind Speller, a thought-to-text device intended to help people with movement disabilities. The system does rely on a lot of processing on a remote computer, but it is a wireless system. And these thought-to-computer systems have wider applicability than medical support. One of the research groups involved in this development has already looked at wireless electroencephalography (EEG) to enable measures of emotion to be fed back into computer games."
