Controlling Games and Apps Through Muscle Sensors 47
A team with members from Microsoft, the University of Toronto, and the University of Washington have developed an interface that uses electrodes to monitor muscle signals and translate those into commands or button presses, allowing a user to bypass a physical input device and even control a game or application while their hands are full. The video demonstration shows somebody playing Guitar Hero by making strumming motions and tapping his fingers together, a jogger changing his music without having to touch the device, and a man flexing a muscle to open the trunk of his car while he carries objects in both hands. The academic paper (PDF) is available online.

i did a bit of math ones, as i considered doing a input glove using pressure sensors on fingertips.
what i found that 2 to 4 finger combos should cover the keys of your average keyboard.
that is, pressing between 2 and 4 fingers in sequence, before releasing one or more could act as a single key input.
and this muscle sensor system could work the same way, as the thumb against other finger system could just as easy be replaced with a system where you have a rest state, and then a added strain state where the muscle controlling the finger is being tensed.
i suspect that with training, a person could type out messages while gripping some object, simply by tensing the finger muscles in specific sequences, just like touch typing today, or for that matter playing a piano...
