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. |
