This paper presents the object location estimation system in Sensing Room, a living-room type sensor-embedded environment, based on the technology of active type RFID. Within Sensing Room, high resolution pressure sensors are distributed in various spots including a floor, a bed, and chairs to track a person's location in the room. In the active RFID system, the signal strength of radio frequency wave transmitted from RFID tags are utilized to determine their distances from the RFID reader. In the experiments, active RFID tags are attached to several objects in the environment equipped with three RFID readers. The estimation of object's location is based on 1) the radio frequency signal strength retrieved from RFID system, 2) the interaction between a person and surrounding objects in the room, and 3) the information of a person's location. The experiment result has proven that the integration of these three main sources is sufficient for estimate the objects' locations in a daily situation.
