I have been thinking of a controller like this, which would be pretty fun to use for space games.
The ellipsoid marked as "Hand Piece", is supposed to be braced to the frame with motion encoders and need to push back the Hand Piece to the 0 position in case the user stops adding force in any direction.
Additionally, the hand piece can also have 5 buttons, 2 placed for the thumb and 3 placed for the 3 longer fingers each, with the button for the middle finger being a scroll wheel.
This should make up for actions like, Primary and Secondary fire, Target lock and cruise control adjustment, hence freeing the second hand for controlling utilities on the keyboard, or eating snacks. Whichever you prefer.
Oh! It's one of those low-movement force actuated thingies!
As a HiDPI user, this seems to fit very well to my needs and would be much better than having stuff travel for a few centimeters to register thrust.
Since you have used it, could you tell me the lifetime of these things? Can I expect them to keep working for at least a decade as long as I don't abuse them?
