Indoor human positioning tracking technique to support high-quality life

Information communication technology (ICT) is expected to assist the activities of senior persons for raising their quality of life. This paper proposes an indoor human position tracking technique using UHF-band RFID (radio frequency identification). Seniors are liable to forget where they put items, such as a wallet or watch in the house. They could find the lost item if they could recall their movement history. The proposed technique is well satisfies this goal. This paper proposes a new simple positioning technique based on RFID. Simulations and experiments are conducted to confirm the basic performance of the proposed positioning algorithm.
