Ubuntu shows off prototype technology based on computer-vision

Canonical, the maker of Ubuntu Linux, demonstrated prototype technology that takes webcam input and analyzes the user’s movements. Its underlying idea is similar to Nintendo Wii and Microsoft Kinect. The prototype behavior described in the canonical design blog is as follows:

1. When a user steps away from the screen while watching a movie, the program automatically expands it to fullscreen.
2. When a user is away from the screen and a notification arrives, the program automatically expands it to fullscreen.
3. When a user moves, the screen moves with them. See the video below.
