I was just guessing, the angle where you got a good view (ie well-focused) looked quite small to me (but maybe it was too late in the evening ;-)) Maybe I'm understanding something wrong, but I think your 'sheet of paper' example is wrong, as the angle it proves to be visible is depending on both the width of the paper, and the distance between your eyes and the paper... @John: obviously, check yesterday's post I link to at the top of this article. @Joachim: object tracking in picture sequences isn't that easy, unless the tracked object is really distinct from other parts of the image. For the wiimote it's much easier: there'll most likely be only one IR source around, where the IR light could even be of some specific wave length (inside some range, that is). Normal webcams don't register (or filter) IR light from the visual though, before sending it to the PC, afaik. Maybe I should dig up my old webcam and check whether there are any good Linux drivers by now, and play around with it a little :-) @Anonymous: it might take some time until I finish next article(s), exams here.

Or is the the crucial part of the wiimote the detection speed?

You'd need to check a more accurate source than my rememberings, but the human field of view is definitely more than 90° : just put the corner of a blank sheet of paper under your nose, you will easily see far beyond the edge of the sheet on the sides.

I'd also love to see your explanation of the head-tracking math. I find this subject quite interesting, and I personally would *love* to see the math, trig and all.
