Display energy, user monitoring, eyes tracking,
This paper discusses a new technology for reducing energy of computer display. Unlike existing power management schemes, which link the display operation to a key press or movement of the mouse, we use vision sensor to bind the display power state to the actual user’s attention. The technology tracks the user’s eyes, keeping the display active only if the user looks at the screen. Otherwise it dims the display down or even switches it off to save energy. We implemented the technology in software and hardware and present the results of their experimental evaluation.
