About

Ken Ukai is a researcher specializing in robot technology (RT) services, human-robot interaction, and intelligent space design, with a particular focus on the concept of *Kukanchi* — interactive human-space design and intelligence. His work addresses the challenge of enabling robots to understand user intent and situational context in shared human-robot environments, contributing foundational frameworks for context-aware service delivery. Among his most notable contributions is the development of RT ontology, a structured knowledge representation system that allows robots to provide situation-appropriate services. Ukai introduced the influential distinction between "main tasks" — explicit user requests — and "Tsuide tasks" (accompanied tasks), secondary yet essential actions that enhance service quality and user experience. This framework has been applied to user RT-service generation systems and service management architectures, helping bridge the gap between abstract user needs and robotic execution. His research has accumulated citations across multiple publications, with his foundational 2009 ontology paper being his most recognized work (11 citations). His contributions to ubiquitous robot technology and context monitoring of human daily activities further demonstrate his commitment to building smarter, more adaptive robotic environments that meaningfully integrate into everyday human life.
