With Wm+, the bar is only used as reference for pointing at the screen (to know where the screen is), but that's all, with the comined sensors you have the position and rotation. For motion controls, the Wii remote does not need to point at the bar. This is way much cheaper than a camera |
WM+ detects rotations only. The absolute position of the Wiimote is determined by the IR camera.
Motion controls don't need to poitn at the bar only if they don't depend on where you perform them.
