About

Hiroki Nagai is a researcher focused on human-robot interaction and cognitive robotics, with a particular emphasis on developing assistive technologies for aging societies. His key research areas include social robotics, group conversation facilitation, and non-verbal communication in human-robot interfaces. Nagai's most notable contribution is the development of the "Bono-02" cognitive robot, designed to assist group conversations by incorporating laughter motions and turn-taking prompts. This work addresses a critical societal challenge: the increasing prevalence of dementia in Japan's super-aged society, where reduced social interaction is a known risk factor. By engineering robots that can actively engage and stimulate social dynamics, Nagai aims to mitigate cognitive decline through enhanced social connectivity. His research has garnered attention with citations reaching into the hundreds, reflecting its relevance to both robotics and gerontology. Nagai's innovative approach—blending affective computing with practical eldercare solutions—positions him at the forefront of socially assistive robotics, offering promising pathways for improving quality of life in aging populations.
