About once a year I have cause to set up a projector, and every time I wonder why the projector doesn’t have a small camera embedded within it that it could use to aim, focus, and adjust the keystone and angle itself. UVa alumnus Johnny Chung Lee has created just such a system, which he demonstrates in this very impressive video. He provides some further examples to show that this has much wider applications than for setting up projectors. You’ll remember Lee for his brilliant Wiimote hacking a couple of years ago.
