I suppose that anything we can think of will probably have been done before, but I don't think that this is a problem since it's just really an exercise.

What about a foot operated controller to replace the function of a computer mouse for people without upper body movement. Perhaps it could have two modes, like mouse mode or joystick mode for cases where mouse style movement is limited. In joystick mode you could have some nice variable sensitivity to allow fine positioning which would at least give it some non trivial software aspects. Also you could use a standard serial interface to make the "hardware interfacing" part pretty easy.
