Low-Cost Multi-point Interactive Whiteboards Using the Wiimote
http://www.cs.cmu.edu/~johnny/projects/wii/ >_ 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, multiple pens can be used.
The calibration and mouse cursor emulation software is available for you to download and try yourself. Note: My mouse emulation code isn’t perfect. If any of you are programmers and can get it working with Alias sketchpad, drop me a line.
1. Connect your wiimote to your PC via Bluetooth. If you don’t know how to do this, you can follow this tutorial
2. Download the Wiimote Whiteboard sample program. 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.Multitouch: The multitouch demos are custom C# DirectX programs. You may download the source code, but this is provided for developers without support or documentation. The code is built on top of this Wiimote library. Unfortunately, multi-touch capable applications are currently extremely rare. Hopefully, that will change as more developers explore its potential.Tip on building pens: You might be able to jump start your experimentation with this by retro-fitting a mini keychain light with an IR LED. Also, apparently this website sells IR penlights. Though, I haven’t tested them and mostly likely come with toggle on/off switches which is wrong type of switch but maybe a better start than nothing.
Mac Version: A Mac version is not currently available, but may show up in the next couple of weeks.
