About
Michiya Yamamoto is a Japanese researcher specializing in human-robot interaction, embodied agents, and social communication systems. His most significant contributions center on the precise timing dynamics between verbal utterances and communicative actions in face-to-face greeting interactions — a nuanced area with meaningful implications for designing naturalistic robots and computer-generated characters. Through a sustained "analysis by synthesis" methodology, Yamamoto systematically investigated how time lags between speech and physical communicative gestures affect the perceived naturalness of robot and CG character interactions. His foundational 2004–2005 studies, each accumulating 18 citations, established that humans naturally delay utterances approximately 0.3 seconds relative to communicative actions, a finding he translated into practical design principles for embodied interaction systems. He extended these insights across platforms, including voice-driven robots and CG characters, demonstrating their broad applicability. Beyond timing research, Yamamoto explored educational robotics with a hand-raising robot designed to encourage classroom participation, personal life-logging robots, and long-term social robot impression studies. His more recent work examining embodied actions in Japanese comedy performance reflects an imaginative expansion into cultural and entertainment contexts. Across his career, Yamamoto's research offers foundational principles for making artificial agents feel genuinely human in everyday social exchanges.
