I'm confuse about multitouch data from Wiimote. Because I've read an article that Wiimote has 4 slots to save the position. I tried 2 IR pen. When my Wiimote catch a sensor, it suppose to save it in slot 1. After that when the wiimote catch another sensor, it will save it in slot 2.

But mine has different case, the first sensor save in slot 1. If second sensor is founded, then the value in slot 1 moves to slot 2 and the second sensor save in slot 1.

And also sometimes, the first sensor always save in slot 1. I fell confuse

Hi,

The Wiimote will continuously track the IR dot if it is in the field of the Wiimote all the time. If there is another new point, the new point will be stored in the second position.

If the IR dot is out-of-view,switched off or temporarily not detected for just a moment, the position will be lost. For your case, there may be a possibility that the IR dots are not continuously detected and thus it will randomly shuffle between the positions.

Also, if you are using a non-genuine Wiimote, unpredictable results may occur such as your case.
