How we created an interactive whiteboard with low cost!!

 What we used:

1.      A wii-mote (wii console controller)

                2. A bluetooth Dongle

3.      The appropriate software

4.      IR Led Pen

5. A PC

          6. A Projector

   Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

Software

 The calibration and mouse cursor emulation software is available for you to download and try yourself. (http://johnnylee.net/projects/wii/ )

1.      Connect your wiimote to your PC via Bluetooth. There are a number of tutorials online on how to do this, possibly even for you specific software/hardware configuration. The Wiimote works with many (but not all) Bluetooth drivers. You can report/read about compatibility issues at WiimoteProject.com

2.      Download the Wiimote Whiteboard software to the right. Please read the “READ ME.txt” file first! Make sure your wiimote is connected via Bluetooth, and then run the “.exe” in the main folder. NOTE: Good placement of the wiimote is key to good tracking. View the README for more info.

Building pens:

Here is a simple schematic of the light pen. Lots of IR LEDs will work . You also might be able to jump start your experimentation by retro-fitting a mini keychain light with an IR LED. Here are some helpful pictures:

Here is a useful tutorial on Youtube on how to build your own infired pen:
