About

Toshihiro Tashima is a pioneering researcher in human-robot interaction, with a focus on emotional robotics and physical human-robot communication. His work challenges traditional industrial robotics by exploring how artificial emotional creatures can engage humans through touch and behavior, rather than mere task efficiency. Tashima’s most cited paper, “Emergence of emotional behavior through physical interaction between human and robot” (2003, 150 citations), demonstrates how robots can express and evoke emotions via physical contact, laying groundwork for socially assistive robots. His follow-up study on subjective interpretation (2003, 58 citations) further examines how humans perceive robot emotions during physical interaction, highlighting the role of context and user expectations. Earlier, Tashima developed an interactive pet robot with an emotion model (1998, 48 citations), one of the first platforms to integrate life-like emotional responses into a robotic pet. This work influenced subsequent research in affective computing and companion robotics. Collectively, his contributions have shaped the understanding of emotional embodiment in machines, with over 250 citations across his key publications. Tashima’s research remains foundational for engineers and psychologists designing robots that interact naturally and meaningfully with people.
