介绍了一种基于摄像头的计算机显示屏电源管理原型硬件设计。该设计仅在计算机用户实际存在时才保持显示活动。否则，它会关闭显示器以节省能源。硬件以真实的时间（30 fps）运行，功耗仅为150 mW;比软件实现低35倍。
This paper introduces a prototype hardware design for camera-based power management of computer display. The design keeps display active only when the computer user is actually present. Otherwise it switches the display off to save energy. The hardware operates in real time (30 fps) and consumes only 150 mW of power; 35 times less than software implementation.
