This paper introduces a novel approach to enhancing safety through RFID technology, location tracking, and monitoring person-object interaction. We design and develop RFID-based wearable devices for (1)tracking people’s locations, (2)monitoring person-object interactions, and (3)tracking objects’ locations. An intelligent object reminder and safety alert system is proposed to relief the common safety-related worries many of us face in our everyday lives - “Where did I leave my keys?”, “Did I turn off the stove?”, or “Did I close all the windows in my house?” etc. Experimental results on the precision of object identification and location tracking are also presented.
