In Project 1, Romeo and Juliet we learned how to make Processing talk. In this project, we will learn how to make it see and dance. We will use Microsoft's Kinect to implement the seeing part and a dancing human to teach a group of stick figures how to dance. Unless you find someone else who is willing to lead your stick figures, you will have to get up and dance yourself.
Computer vision and 3D scanning have long been the domain of very specialized and expensive hardware and software. With the ever increasing computing power of CPUs and graphics cards, and new hardware controllers like Kinect, computer vision projects have invaded living rooms via various game controllers, and are accessible to everyday programmers like you and me.
