複数のウェアラブルセンサデータ間の時刻同期手法の検討(Study of Time Synchronization Method between Multiple Wearable Sensors)

In this paper, we describe a time synchronization method between multiple wearable sensors for activity recognition. Time synchronization method is achieved by the correlation between sensor data from multiple sensor device. We propose two methods: 1) one based on the mean square deviation, and 2)the other one, based on the average sum of squares of tangents between axes. In order to evaluate the proposed methods, we have several experiments using sensor data obtained from the same action.
