Current Progress:

Synopsis: We are currently working on a multi-touch solution using a webcam to track color bands on a finger.  We are only able to track one color at the moment, but the program will soon be able to track multiple color.   

Method:  
1) We use the quick time java library to capture video contents from the webcam/iSight.  
2) We use a statistical regional matching algorithm (see reference) to segment the video frames into statistically important regions.  By employing this extra step we are able to reduce the amount of noise.
3) We use a color tracking algorithm to find the object of importance

Here is a demo video of color tracking program.  The window on top left is the post processed image after running the video through the statistical region matching algorithm.
