We propose a novel method for locating tagged items that uses a RFID reader, a smartphone, and unregistered RFID tags attached to a variety of items, furniture and places. As a user moves through a room to locate a target item, our system shows relative distances to the target item and images of items on the way to the target. At the same time, the system scans RFID tags nearby and captures images for scanned RFID-Tagged objects. This information is accumulated in a database and is accessible for future item location activities. Since all information was gathered during users' searching activities, the proposed system does not require users' effort for managing and registering tags. We asked 10 users to compare our method with the conventional method, which shows RSSI of the target item, of searching for the target item. The results suggest that our method is effective for location target RFID-Tagged items.
