These are some top notch geeks. They built a setup to compute and project the trajectories of pool shots directly onto their table. It doesn’t work terribly well, but I think it is mostly a problem of low end hardware and strange setup. Why didn’t they put the webcam by the projector, pointed at the mirror? Â By having it in the corner they make things immensely more difficult to compute.
I think once Surface goes mainstream, innovations like this will come in a flood.
