Object Localization by Cooperation between Human Position Sensing and Active RFID System in Home Environment

摘要

We propose methods for object localization by cooperation between human position sensing and active Radio Frequency Identification (RFID) system in a home environment. The traditional object localization methods based on received signal strength indicator from active RFID system suffer from the distortion of RF signal caused by human existence. Two proposed methods improve this problem using a human position sensing system and pattern recognition technique. One method selects the classifiers based on human position in object localization. The other method narrows location candidates using position data and detection data of human handling motion with the sensor embedded in the active RFID tag. The experiment in the human natural handling scenario demonstrated that the methods improved the performance of object localization in human existence.
