Sensors are emerging as a key area of interest in operating systems research, with a main focus on sensor networks. Turning the relationship around, we propose the use of low-power sensors as tools for improving OS-based energy management. Using sensors to detect user intent and physical context we can more directly match system I/O behavior to user needs. FaceOff is a prototype display power management system designed as a test bed and proof-of-concept.
