This is a demo to show how Angry Birds (its web version) can be played with a Kinect by combining Skeltrack and OpenCV.
Skeltrack is used to track where the user's hands are, their position is used to move the mouse. OpenCV is then used to get the ConvexityDefects from the hands' image which gives us the number of fingers; this can be used to know if the hand's palm is open or closed and simulate a mouse press according to this state.
The end result is not yet polished but it gives a good idea of what can be done with 100% Free Software.
