| Abstract(in English) | Accelerometers offer a practical method to monitor human activities continuously. We are trying to develop a system of supporting life management by exploiting sensor data measured for long-term periods. For this purpose, we need to recognize high-level activities such as deskworks, meals, commutings, which are important for discovering daily routines or lifestyles. These high-level activities are composed of various low-level activities and their context, therefore, we need to analyze sequences of time series data of low level activities for recognition of high-level activities. As a preprocessing operation of recognizing high-level activities, we propose a change point detection method of human activities to split out time series data of one low/high level activity. Our proposed method detects change points of activities by analyzing changes of statistical distributions of the posture of an arm. |
