The wiimote whiteboard is an idea from Johnny Chung Lee in Carnegie Mellon University.  He has created a number of ingenious projects using the wiimote controller from the Nintendo Wii games console, the most educationally relevant one is probably the wiimote whiteboard.

The wiimote contains an infrared camera, so can detect and recognise the position of an infrared LED in its field of view.  Johnny Lee has written software and devised a method that an infrared LED can be used as a mouse pointer.  This has the potential to turn any surface with a projected screen image into an interactive whiteboard.

This is Johnny’s orginal demonstration on Youtube.  There is now a project homepage on www.wiimoteproject.com

Some tips:  I could not get the program to work under Vista.  To work accurately the wiimote camera has to see the reflected infrared light off the surface.  For a large white board the wiimote has to be a distance back and therefore the LED should be as intense as you can find; power dissipation >100mW.  Some people have used multiple LEDs, this is probably unnessary but max out the LED as you have to make it as bright as possible.  Positioning the wiimote is interesting.  Straight in front gives greatest resolution, but it has the be further away from the board to cover it all than if it is placed to the side.  I have found that on top of the data projector is about the right distance away – it may needed to be tilted upwards.  This has the added advantage that you can power the wiimote off one of the ports on the back of the projector.  The resolution of the system is lower than that of a commerical traditional type interactive board, but wiimotes are spectacularly cheaper.  Good luck.

Hey you try should try using BoonJin’s Smoothboard as well at http://www.smoothboard.net. He has done alot of modification to what Johnny Lee has did.

Smoothboard 1.6 now does not require manual Bluetooth connection but handle automatic connection with the computer through a Bluetooth adaptor using MS Bluetooth Stack.

I have to express my thanks to you for rescuing me from this type of matter. As a result of checking throughout the online world and obtaining proposals which were not helpful, I figured my life was done. Existing without the solutions to the difficulties you’ve resolved by way of your post is a critical case, as well as those which could have negatively damaged my entire career if I hadn’t discovered your website. The talents and kindness in controlling all the pieces was invaluable. I am not sure what I would have done if I had not encountered such a solution like this. It’s possible to at this point look ahead to my future. Thanks very much for your impressive and result oriented help. I will not be reluctant to suggest your web site to any person who would like counselling on this subject matter.
