Abstract :
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.
