Novel RFID and Ontology based Home Localization System for Misplaced Objects

Abstract — Smart Home systems that can help track and localize objects within the home have been an important part of Consumer Electronics research in recent years. In practical terms, these systems can help people find certain things, such as glasses, wallets, keys, etc., and it is often troublesome to look for them. Previous research has shown great achievements in terms of localization accuracy of up to about 10 cm. However, no existing solution gives a meaningful description of the location of the misplaced object related to important known areas in the home or other space, which are easily understood by the user. This study proposes an RFID and ontology-based solution to localize the easily-lost objects based on three nearest reference points and recommends how to build the localization system so that it can be easily integrated into the entire Smart Home system that adheres to the Semantic Web protocols. The solution generates localization results as user-friendly statements, e.g. “The glasses are at the kitchen table”. The current highest accuracy rate of 87.5 % encourages enhancement of the technique and implementation of the complete system1. Index Terms — Smart Home, assisted living, lost objec
