About

Keiichi Yamazaki is a pioneering researcher at the intersection of human-robot interaction, computer-supported cooperative work, and sociological interaction analysis. His work is distinguished by a unique "techno-sociological" methodology, combining ethnographic fieldwork with robotics engineering to design systems that authentically replicate the nuanced nonverbal behaviors humans use in everyday communication. Yamazaki is perhaps best known for his extensive work on museum guide robots, exploring how robots can engage visitors through head gestures, body orientation, and precisely timed verbal and nonverbal coordination — research that has garnered over 400 cumulative citations across multiple studies. His 2007 and 2008 papers on sociological interaction analysis and precision timing (136 and 131 citations respectively) established foundational principles for socially intelligent robots. His earlier work on GestureMan (2000, 120 citations) demonstrated how remote collaboration systems must account for embodied, nonverbal expression. Beyond museums, Yamazaki has examined service robots in elderly day care settings and remote instruction systems, consistently emphasizing the importance of spatial formation and projectability in multiparty interaction. His body of work has profoundly shaped how researchers approach the design of socially competent robots, bridging sociological theory and practical robotics engineering.
