About

Akifumi Tokosumi is a pioneering researcher in human-robot interaction and cognitive science, with a particular focus on the dynamics of long-term communication between humans and intelligent artifacts. His most cited work, "An Intelligent Artifact as a Cohabitant: An Analysis of a Home Robot's Conversation Log" (2007), stands as a foundational study in domestic robotics. In this landmark paper, Tokosumi analyzed an unprecedented 16-day experiment, applying protocol analysis to user utterances captured by a home robot's voice recognition system. This work revealed how humans naturally adapt their communication patterns when sharing living spaces with robots, offering early insights into the social integration of AI companions. While his citation count remains modest, Tokosumi's contributions are highly influential in the niche field of cohabitant robotics, where he helped establish methodologies for studying real-world, long-duration human-robot interaction. His research bridges cognitive science and artificial intelligence, exploring how intelligent artifacts become more than tools—evolving into cohabitants that reshape human communication and social behavior.
