And I happened across an interesting thing on page 5. The side sticks that NASA were testing were more sensitive when rolling right than left:
In short, since your arm is stronger when pulling inward than outward, they found that making rolling right more sensitive than rolling left was more ergonomic.Of particular note, these side sticks have stiffer gradients for left roll commands than for right to accommodate the differences in strength among the various arm muscles used for roll control. Because the arm is less able to push away from the body than pull towards it, the gradients were configured to provide a constant feel in roll, offering an ergonomic advantage.
Rolling left, the stick had a maximum displacement at 8 lbs. Rolling right, the stick had a maximum displacement at 6 lbs. In the current FSSB firmware, you can't set different values for left and right roll sensitivity.
These sticks are different, however, in that they allow much more deflection (1-2 inches depending on axis) than the FSSB. Also of note is the high deadzone on these NASA sticks (I think this is what they refer to as "breakout force"). Nonetheless, this is something I'd like to try with the FSSB. It would also be cool to try different sensitivity for pitch up and down. Would this be possible to implement in the firmware and possibly the HID device tool?
