About
Yuma Nagata is a pioneering researcher at the intersection of gerontechnology and human-robot interaction, focusing on the long-term use of socially assistive robots (SARs) to combat social isolation and cognitive decline in older adults. His work critically examines both the psychological benefits and ethical implications of companion robots, including concerns about emotional deception and reduced human contact. Nagata’s most-cited paper, “Long-term effect of the absence of a companion robot on older adults” (2023, 21 citations), highlights the nuanced impact of robot withdrawal on frail seniors. His landmark 18-month case series (2026) is among the first to demonstrate sustained psychological support from conversational robots for individuals with mild cognitive impairment or late-onset psychosis living alone. Through pilot trials and feasibility studies, Nagata has shown that robotic companions can reduce loneliness and improve emotional well-being in vulnerable populations. His cumulative work, with over 50 citations, is shaping ethical guidelines for deploying SARs in home settings and informing the design of more empathetic, long-term robotic interventions for aging societies.
