Hi,

If you intend to use Johnny Lee's finger tracking program, then you can just use both the Whiteboard and Finger Tracking program simultaneously but connected to different Wiimotes.

For finger tracking, you will need an IR on the fingers for tracking or via reflection from an IR array.

Yeah, you can do it but it may take some work to do. You will need to connect the Wiimotes and then assign the events accordingly.

Hi,

You will indeed do some modifications to the software. It would be easier for you if you take a look at the WiimoteTest application that comes with Brian Peek's Wiimotelib where several Wiimotes are connected simultaneously.

Hi,

You should get a high-powered IR LED with a wavelength of 940nm.

Most of our resellers do sell the Vishay TSAL 6400 and ship internationally.

For example,
