i hope to make a large interactive white board(IWB),using three projectors together.but after i test,only one wiimote doesn't support this size. Pls kindly tell me who have experience on multi-wiimote IWB,thanks advance.
Another question:if i use power infrared led lamp lighting from back of screen(certanily the screen is rear screen),can i use finger instead of IR pen?

A simple question with a complex answer.

The issues:
Rear projection: If the Wiimote is behind then yes you could just use a finger, however you will need to flip the X axis for the calibration

Big screen: The viewing angle on a large screen will require the wiimote to be a considerable distance away from screen, you will need a very bright & defined IR-source current IR-Pens would find this diffcult.

Multiple screens: The one known issue with all Wiimote IWB applications if eronious results when using multiscreens.

Multiple Wiimote: Current Wiimote IWB only supports 2x Wiimotes, you will still have black holes in the calibrated area.

Summary
This is doable (could be very cool) but you will need to do extensive work on the programing and hardware if you wnat success. If you have the skills or access to a team with the skills, it would be an amazing thing.

If you want to make a multitouch IWB (Please say yes ;D) then I suggest you integrate the following:

1. Johnny Chung Lee's Wiimote IWB V3 (speak to Boonjin as their was a number of significant bugs that you will need to fix first
2. Johnny Chung Lee's multitouch code
3. Kindlelab opensource IWB application (http://www.kindlelab.com)

Once you have the concept working then go for the big screen. If you start on the big screen and combine all these application you will be dealing with a very complex problem that will be very difficult to problem solve.
