The paper presents a model to identify person's actions using non-portable vibration sensor. In Japan, because solitary aged persons, who require the care, rapidly increases, a watching support system is needed to protect such aged persons. Vibrations generated by person's action are monitored by a non-portable vibration sensor. Some indices to evaluate the degree of similarity among different monitoring vibration data are formulated and are integrated based on the principal component analysis. Proposed similarity judgment method applies to an actual wooden 2-story house and discusses the judgment accuracy. As a result, it is shown that the purposed model enables us to accurately identify 15 person's action modes using a single non-portable vibration sensor.
