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...
