You may have been joking, but this is a project that (seriously) interests me. I have always felt that it would be fairly simple (facile compared to speech or picture recognition) to connect a few electrodes to different tiny muscles (jaw, eye, face, finger, toe) and use the relatively large spikes from moving these muscles to control a cursor, or even do complete typing. I have great faith in the human animal being able to learn how to control something very complicated via difficult motions (for instance, positioning his fingers over a pre-defined spot on a board with cells labeled QWERTYUIOP... and pressing down, without looking).

If there are any Bio-electronics people out there, I'd love to actually do the project. I KNOW it can be done, but I have not the knowledge to grab the signals off the body (the rest is easy).

This may seem like a trivial question, but remember back to when you didn't know the answer, and then tell me:

What's inside a mouse or trackball? How is the relative motion data gathered?

Please send responses to me; I will send back to the mailing list the clearest.
