Have you ever considered integrating with OpenTrack somehow? It provides all of the controls for mapping inputs to outputs such as mouse emulation and joystick and also provides controls for adjusting the sensitivity via curves. I’ve attached a screenshot. Might be a cool thing to have as Input the Driver4VR and then would open up tons of possibilities.
Also, just want to clarify my prior post what we want to map is Yaw and Pitch to the X and Y movement I think I previously referred to Yaw as X and Pitch as Y.
