• Nintendo's Wii MotionPlus add-on makes the Wii Remote a true 1:1 motion controller
  Which is, y'know, what we thought it was in the first place. But still - great news!

The wiimote is based on accelerometers, so it has several aspects that mean it's not precisely 1:1 spatially. The initial orientation and position of the wiimote relative to the wii can't be established precisely, and because the current positions and orientations are calculated as the path integral of the physical quantity that's *actually* being measured, errors will accumulate and so the calculated position will drift over time. I'm sure the wii probably uses heuristics of some sort to account for this in the current wiimote.

Certain other forthcoming 3d controllers are 1:1 from the get-go.

Oh, yes - I know that. It just wasn't originally sold that way - it was sold as "it can tell exactly where it's pointing!".

The new addon looks pretty good though - according to some writeups I've seen it looks much more accurate. They were swordfighting at the Nintendo press conference :->

I'll wait and see some actual reviews before I get too excited though.

Oh - and doesn't the Wii's sensor bar mean that it's got an orientation/position reasonably well established?
