This article presents a hybrid system of wireless sensor networks and active tags in order to monitor user's behaviors of handling objects. The sensor networks consist of an acceleration sensor node that the user carries and occupancy sensor nodes that are deployed in a workplace. The active tags, which are embedded with switch sensors, vibration sensors and occupancy sensors, are attached to objects. The sensor networks capture the user's movements and the active tags detect the objects' movements. The sensor nodes have the parent selection function that can allocate resources to the nodes. We demonstrate monitoring the user's behaviors of handling the objects using the hybrid system. We also show that the proposed system provides the useful information for behavior classification.
