本文介绍了一种计算机显示器节能的新方法。与现有的电源管理方案，其中链接的显示操作的按键或鼠标的移动，我们采用了摄像机绑定显示电源状态的实际用户的注意力。所提出的方法仅在用户看屏幕时才保持显示活动。当用户将注意力从屏幕上转移时，该方法会将显示器调暗，甚至关闭显示器以节省能量。实验表明，该方法可以显着降低显示能量的环境中，经常分散显示观众。
This paper introduces a new method to save energy of computer display. Unlike existing power management schemes, which link the display operation to a key press or movement of the mouse, we employ a video camera to bind the display power state to the actual user's attention. The proposed method keeps display active only if its user looks at the screen. When the user detracts his/her attention from the screen, the method dims the display down or even switches it off to save energy. Experiments show that the method can reduce the display energy significantly in environments which frequently detract the display viewer.
