About

Joji Maruyama is a pioneering researcher in the field of human-robot interaction, with a specific focus on therapeutic applications for elderly individuals with dementia. His work centers on the design and evaluation of robot-assisted recreation, aiming to improve the quality of life for aging populations. Maruyama’s major contributions include demonstrating how pet-type robots can be used as tools for game-based recreation, providing quantitative evidence of their benefits in nursing home settings. His most-cited paper, "Robot therapy as for recreation for elderly people with dementia - Game recreation using a pet-type robot -" (2008), has garnered 32 citations and remains a foundational reference in robot-assisted therapy. In a related study, "The Study on Robot Motion Planning in Recreation for Elderly Person with Dementia" (2008), he proposed methods for designing effective recreational activities by analyzing the relationship between robot motion and therapeutic outcomes. Though his citation counts are modest, Maruyama’s work is notable for its early and rigorous attempt to quantify the effects of robotic recreation—a critical step in validating the use of social robots in dementia care. His research continues to inform the development of compassionate, evidence-based robotic interventions for vulnerable populations.
