One of the first things I found was this. The issue is a VR has a frame of reference. That is motion is relative to some defined object like a head tracking camera. If your spec had relative offsets for its positioning on top of just the acceleration then it might work. Basically optional parameters to the event. Also as I asked in another post I'm not sure if position and acceleration are enough and if we should also have velocity also. (rather than the user computing it). As for orientation though the same applies. Do we need angular acceleration and angular velocity? Someone here might know.
