None that I know of. Controllers already have too few buttons as it is. I imagine it would have to be something that at least utilizes all 5 digits, even then, I imagine navigation in a 3D world would be ... bad, even with something like a gyroscope in place of a second analogue stick, unless a stubby one could be made for the index or middle fingers, maybe? And then you might even need some kind of layer button to have enough separate inputs for somewhat modern games.
