| Abstract(in English) | By attaching sensor nodes to physical objects in a sensor networked environment, the object expression method introduced here infers what the physical objects are and their states. The method does not assume that initially the sensor nodes have information about the objects to which the sensor nodes are attached. The sensor nodes collect data by sensing humans' daily living in the environment for a certain period of time. The method compares the collected data with metadata of physical objects prepared in advance and determines a presumable metadata where the collected data can be observed. Object metadata are described by using state transition diagrams where object states and its transitions between states are represented by an graph structure. The method also permits us to infer objects' states. |
