Hi!
I was just wondering when in the documentation it says  the camera's field of view is 45 degree, is it half of a sysmetirc angle meaning 90 dergree in total or not in totat it is 45 degree? If it's 45 degree in total then it should be such a small range!
What do you think!?

Hi,

The wiimote field of view is indeed small. From my own experimentation, it is only around 40-41degrees.
Therefore, half the angle is only 20.5 degrees.

Ok!thanks ,yeah it is really small. Perhaps that explains why incorporating two wiiuse gives more robust estimation!

If you're hurting for more space with only one wiimote, a mirror could always work, but inherently more problems would make themselves known. It's something I've been experimenting with.
