I have often wondered if any camera mfg ever tried using a static actuator (like the buttons you sometimes find in elevators) to trigger the shutter release instead of mechanical means. I ask this because a lot of camera shake comes while pressing the shutter release button down. Of course there would be a problem holding the button half way down, but it might eliminate a lot of trouble for jerky shooters. Just a quick tap and viola your shutter's released. I suppose you could end up with an inadvertent shutter release or two, also. Still, it seems like something to try if it hasn't been done before. This may not be a beginners question but I couldn't see anywhere else to ask it. What do you thing?
