Blacklaw writes "Canonical's Christian Giordano has posted details of what he believes could be the future of user interface design in Ubuntu — a system that detects physical context. Designed to be paired with a webcam or other sensor system, the concept is that the computer is able to detect where a user is in proximity to the display along with an idea of roughly what he or she might be doing. Using this information, the operating system — in this case, Ubuntu Linux — can automatically make changes to the screen layout. For example, when the system detects that the user has leaned back in his or her chair, the system automatically makes the currently playing video full-screen. Lean forward again, and the video returns to its previous windowed mode."
