This paper presents the design and implementation of Ferret, a system for locating nomadic augmented with RFID tags and visually displaying them to a user in real-time. The authors present a novel algorithm to infer location of tagged objects using the location of a camera and reader that observes them. They also present techniques to refine location estimates using multiple observations and a method to display and update object locations on a video camera screen.
