Abstract(in English) | We propose a real-time living activity recognition method using only off-the-shelf sensors, namely, an accelerometer and a microphone, which are commonly applied in mobile phones. The proposed method firstly estimates a user's movement condition such as "walking," "working" and "quiet" roughly by acceleration sensing. Secondly, it classifies the working condition in detail by acoustic sensing when it estimates the condition to be "working" by acceleration sensing. We developed a prototype system to recognize the user's living activity in real time and conducted two experiments to confirm the feasibility of the proposed method. As a result of the first experiment, three movement conditions were classified with more than 95% accuracy by acceleration sensing. And it classified working into seven conditions with 85.9% accuracy on average by acoustic sensing. Moreover, the result of the second experiment shows that it is effective to adopt instance-based recognition according to the assumed application. |
