Mapping Yourself and Your Gaming Room

A while back, I discovered that a method for increasing pointer accuracy used in the setting screens for the Wii version of Zelda: Twilight Princess could be used to tell the game where your screen is in 3D space relative to the sensor bar. Then, if the system knew where the sensor bar was in 3D space relative to the Wii remote, it would know where the screen is relative to the Wii remote.

However, I've just realized there's a much easier way to tell the system where your TV is in 3D space.

Tracking Hands

Currently, the Wii MotionPlus (WiiMot+) is capable of tracking its own movement in 3D space one-to-one. However, by conventional means it can only track this movement relative to the location it was at when the WiiMot+ was powered on. That is, if you held the WiiMot+ three feet above the ground, turned it on, made a motion, turned it off, turned it on again a foot higher and made the same motion, the WiiMot+ would not be able to tell the difference.

With 6DOF head tracking though, it is possible to tell the WiiMot+ exactly where it is located in 3D space regardless of when and where you turn the device on.
