According to the Trackir doc:
"Combining the X and Y values into one coordinate determines how much motion scaling will occur at various points of your actual head movement. For instance, a control point coordinate of (15,3) would result in your ingame view control being 3x your actual head movement when your head is at 15 degrees. So, 15 degrees of real life movement would result in 45 degrees of in-game movement."
In my case with x=30 and Y = 12 and a real head yaw of 30 degrees I get an in game head yaw movement of 94 degrees. In my math 30 times 12 = 360 per the docs. I'm using Trackir software version 5.4.2.54273 and a Trackir4 under windows 10 with a Trackhat clip emitter.
Any suggestions?
