Hi,
I’m a student from the universidade fernando pessoa in Portugal and I’m doing a research for my Master Thesis.
My goal is to produce a low cost interactive whiteboard which will allow multiple user on it, so it must deal with collaboration aspects.
Hope I can made some discover to improve things in this area.
For now I’m starting to produce some code in C++ with opencv to capture frame from my web-cam.
And my program will get the coordinate of one or more point of interest in each frame.
I use an ir light and a pass ir filter in front of the web-cam.
If you have any suggestions please let me know 
Christophe
