Technology Review carries an interesting piece regarding a system which allows you to dial a phone number by thinking about the number in question. A head band and a Nokkia N73 (my current mobile as it happens) is all that is required. Well that is not strictly true it is, after all a rather special kind of head band. The technology was developed to help severely disabled people (I asume however that this does not include visually impaired people as it appears, from the article that sight is required to operate the system).
