Abstract
In this paper, we propose the system which identifies user's activities and acquires a life log from impact noise of daily objects in Kukanchi, without using a camera to reduce pshycological load. The logged noise is analized in the frequency domain appling spectram analysis method to identify what things users are using, action discriminate from the combination of thing currently used. We build the system that identifies what things users are using. We made sure if the system can identify the characteristic things with limited scene.
