Uh, ten fingertip sized mice? <smile>
Actually, why not? It would be an worthwhile engineering challenge to
get the spatial / temporal fidelity high enough that you forget that
they're there. Just as long as they wouldn't stop you from typing or
doing other useful things with your hands.
I had a blind friend who was a master audio engineer, and wanted me to
build him a V.U. meter that he'd strap on his arm. I would have done
it, except he really wanted electrical shocks rather than physical
actuators. In retrospect, it probably just needed a constant current
high-voltage supply, but I didn't have the nerve...
