About

Hiroki Nakazato is a leading researcher at the intersection of human-robot interaction and character animation, best known for his pioneering work on bringing expressive, lifelike behavior to home robots. His most cited study, "Production of Character Animation in a Home Robot: A Case Study of LOVOT" (2021, 47 citations), provides a seminal framework for designing non-verbal communication and emotional expression in companion robots. Nakazato’s major contribution lies in adapting principles from character animation—traditionally used in film and games—to the constraints of physical robotics, enabling machines like LOVOT to convey personality and intent through subtle movements, gaze, and posture. This work has been instrumental in shifting home robotics from purely functional tools to emotionally engaging companions. Beyond this flagship study, his research has influenced the broader field of social robotics, with his methods adopted by both academic labs and industry designers. Nakazato’s achievements include bridging the gap between animation artistry and engineering, demonstrating that a robot’s “character” is as critical as its hardware for user acceptance. For students and researchers, his work offers a compelling blueprint for creating robots that feel alive, proving that the most impactful innovations often lie at the boundaries of disciplines.
