When I was a student a few years ago my HCI lecturer talked about a 'keyboard' for mobile phones/ PDAs which would actually consist of sensors attached to the users lower arms. The signals from the tendons (muscle?) movement would be fed back to the PDA via infra-red signals.
The catch? You had to be a perfect touch typist to ensure that the system could correctly interpret, for example, a strech and tap with the left index finger as a 'Y'. Not much good for those of us who skipped secretarial studies in favour of more gym!
