Valve didnt invent this tech. Short flashy exposures of the display is pretty much standard in gaming monitors and everyone knows it is _the_ thing to do to minimize motion blur (LightBoost). Using camera to extract absolute position instead of drifty relative mems trackers is also no brainer. This is what N originally did with Wii remote. N also got sued at least four times over this exact technology.
