About

Norie Uchitomi is a researcher specializing in wireless identification and localization technologies, with a particular focus on passive Radio Frequency Identification (RFID) systems. Their work addresses one of the fundamental challenges in ubiquitous computing: accurately determining the spatial position of passive RFID tags without requiring an external power source in the tag itself. Uchitomi's most significant contribution is the development of the Multi-Sensing-Range Method, introduced in 2008 and accumulating 25 citations, which enables more precise position estimation by leveraging multiple communication ranges of passive RFID readers. Building on this foundation, they proposed the Communication Range Recognition (CRR) scheme, a novel localization framework that exploits variations in reader-tag communication boundaries to triangulate tag positions. This body of work has direct practical applications in mobile robotics, environmental mapping, and pedestrian navigation systems. Across five closely related publications spanning 2008 to 2010, Uchitomi's research has garnered a combined 51 citations, reflecting a steady and focused contribution to the RFID localization field. Their work is particularly valuable for researchers and engineers seeking cost-effective, infrastructure-light solutions for indoor positioning and autonomous robot navigation, areas that remain highly relevant in today's smart environment research landscape.
