Abstract: in this paper we present the improvement of our novel localization system, by introducing radio-frequency identification (RFID) which adds person identification capabilities and increases multi-person localization robustness. Our system aims at achieving multi-modal context-awareness in an assistive, ambient intelligence environment. The unintrusive devices used are RFID and 3-D audio-visual information from 2 Kinect sensors deployed at various locations of a simulated apartment to continuously track and identify its occupants, thus enabling activity monitoring. More specifically, we use skeletal tracking conducted on the depth images and sound source localization conducted on the audio signals captured by the Kinect sensors to accurately localize and track multiple people. RFID information is used mainly for identification purposes but also for rough location estimation, enabling mapping of the location information from the Kinect sensors to the identification events of the RFID. Our system was evaluated in a real world scenario and attained promising results exhibiting high accuracy, therefore showing the great prospect of using the RFID and Kinect sensors jointly to solve the simultaneous identification and localization problem.
