Occupant activity level information is essential in many smart home applications, such as energy management and elderly care. Various methods have been proposed for detecting occupant activities through vision-, acoustic-, or radio frequency-based methods. However, the visual-based methods function only when occupants are in the visual field, the acoustic-based methods are sensitive to noise, and the radio-based methods usually require occupants to carry receivers all the time. These requirements increase the difficulty of deployment and maintenance in typical indoor smart home scenarios.
