It seems like cursor acceleration (breaking the linearity between pixel and physical distance) would make this non-trivial; curious how you implemented it.
Well I wanted to specifically measure cursor distance rather than mouse distance so acceleration doesn't come into it. As long as you can sample the mouse position frequently enough, you can get an idea of how far it has travelled. All I had to do to convert pixels to physical distance was use a tape measure to get the width and height of the visible part of the screen.
It sounds like they measures the distance the cursor on-screen moved, not how far they physically moved their mouse. So accelleration wouldn't be a factor.
