Hi Greg….
With wiimote (and Nunchuk) you can get Pitch, Yaw and Rotation, so with this you can get orientation – Kinect/Leap for position
it has been done with OSVR – but that software is not really user friendly like Driver4vr is….
check out OSVRFUSION

with your software I believe something similar could be achieved…I hope 😉
