Disclaimer: Not a flame, just mechanical thoughts. What you have described is basically the action of a piston valve. (Longer stroke understood) Call me a Luddite, (or slow hand) but my preference is for the simpler, reliable old piston. I can envision your suggestion as something on the lines of a valve train/rocker arm assembly to allow machine parts to take the latteral motion. The other option would be valves under your wrist to follow the finger arc. That seems kind of awkward. In any case it would still be more moving parts to be potential trouble. This all may incite a riot of rotary v.s. piston

I once asked a Colo. State Trooper why he was still carrying a revolver instead of a semi-auto and his reply was that he had not heard of a revolver ever jamming up in the chamber.
