A deactivated passive user interaction sensor may be activated or deactivated on demand based on an expected use of the sensor. The expected use may be ascertained by detecting a predetermined user interaction at another sensor that is already active. Once the predetermined user interaction is detected, the active sensor may be deactivated and the sensor that is expected to be used may be activated. Total sensor power consumption may be reduced by providing a predetermined sensor activation and deactivation sequence for at least three sensors in a computing system based on predetermined user interactions with an active sensor. Methods, apparatuses, systems, and computer readable media are provided.
