A different kind of mouse

I've been looking around the net for different kind of mouse/input devices that are not the int tradition of the standard desk/trackball/tablet concept. What I'm looking for something more akin to the new 'keyboard-less' keyboards that are starting to apear, where the input is sensor based, via a glove or other device you attach to your hand. It would seem to me since this kind of work has been done for keyboards, where it' a much harder problem to solve (detecting exact keyhits based on finger position and so on), it should have been done for mice too, especially since joysticks/gamepads that incorporate similar technology have been available for a while now. However in all my web scouring I've found nothing. Does anyone know of anything like that?
