Cheap interactive multitouch panel using Wiimote
Below I present a translation of an interesting, in my opinion, way to make a multitouch panel using the wiimote remote control. The method coined by a researcher at Carnegie Mellon University Johnny Chang Lee (Johnny Chung Lee). It's amazing what you can do at home.
Using the Wiimote's ability to track the rays of infrared light, you can track the movement of the infrared diode knob. Directing Wiimote to the projection screen or to the LCD monitor, you can create a cheap touch screen or tablet. Wiimote can track 4 infrared points, which means that at the same time, you can use up to 4 rays. Also, the system works fine with rear projection screens.
Cursor calibration and emulation software is available for download and testing. Note: My cursor emulation program is not perfect, and if there is a programmer who can get it to work with Alias Sketchbook , let me know.
1. Connect your Wiinote via Bluetooth to your PC. If you do not know how to do this, see this example . I was informed that this could work with other bluetooth drivers, but I did not check. If you encounter compatibility issues, you can report this to the forum .
2. Download the Wiimote Whiteboard software . Read the "README.txt", make sure that your Wiimote is connected via Bluetooth and run the program in the main folder. Note: The good location of wiimote is the key to better tracking. Read more in README.txt.

Multitouch examples are C # DirectX programs made by me. You can download the source code without documentation. This code is compiled using this Wiimote library . Unfortunately, today, programs supporting multitouch are extremely complex. I hope the situation will change when the developers understand the potential of the technology.
Here is a simple outline of an infrared pen. You can also start experimenting with infrared flashlights, which are easily accessible, but I personally have not tested this method. At the moment I am trying to start the production and sale of infrared pens, but it will take several months.
Mas version is almost ready, I still struggle with big bugs. I'm new to Mac programming, so be patient. You can subscribe to feed updates on my blog. The Linux version will not be made by me, I called for this open source community and created a Source Forge project for the Wiimote Whiteboard . Join us, many people want to use your program!
The FAQ and Advanced Discussion section of my blog can be very helpful.
