Light Gun on a Plasma or LCD screen?

A buddy of mine bought 2 for himself a month or 2 ago, and he seems to like them enough

yeah at each end of the wii sensor there are a cluster of infa red transmitters all pointing at slightly different angles and each tranmitting a slightly different signal. The sensor is on the end of the wii remote and reports which signal it can see, and this can be used to tell where the remote is pointing.

False.

The sensor bar is just two IR emitters. There's no rhyme or reason for their placement or difference between them. They're identical. It's why the Wii will work with two candles placed either side of your TV or any other IR emitting device. It's the reason why all those head tracking and alternate interfaces that people have made where the Wii remote is stationary and the user has a simple IR emitter work.

The remote does all the work. It just needs 2 IR reference points. That is all.

[Ack]

Hell, you can use two candles if you really have to.

The official Nintendo bar is actually two clusters of 5 IR-LEDs pointing in different directions. LEDs tend to be quite directional, so they use them in multiple directions to ensure people (with WiiMotes) sitting at different points in the room see the same intensity IR light.

The WiiMote camera is so low-resolution that it only picks up one big blurry light source, and not the five individual LEDs.

Here's a shot of a third-pary Wii bar that I hacked. You can see the three IR-LEDs close together (again, the official Nintendo ones use 5 per side):
