Optical flow based UI

I created some interesting new user interface widgets using a camera. Most of the camera-based games we created did not require the player to hold a controller to play them so it was important that we could navigate menus without a controller too.

The first part of the video shows a “scroll bar” which could be moved with your hand. This suffered from the problem that it could be accidentally moved by someone standing behind it. The second part of the video is an attempt to get around this problem with a “dial controller” which only responds to circular motion.
