About

Shinichi Ohnaka is a pioneering researcher in human-robot interaction, specializing in the development of socially assistive robots for childcare and elderly care. His most significant contribution is the design and implementation of PaPeRo, a personal childcare robot, which he developed through rigorous field-based observations and iterative evaluations—including a six-month demonstration at the 2005 Aichi Expo. Ohnaka’s work on PaPeRo’s auditory system, featuring advanced noise and echo cancellation for robust human-robot communication, has been foundational, with his 2006 paper on the topic garnering 22 citations. He has since shifted focus to information support robots (ISRs) for older adults, particularly those living alone or with dementia. His 2012 study on field-based development of ISRs for persons with dementia (34 citations) and his 2021 investigation into the effects of such robots on daily activity and sleep patterns (19 citations) demonstrate his commitment to real-world impact. Ohnaka has also explored spoken dialog systems for cognitive assessment, collecting elderly-human-robot corpora to advance computerized screening tools. With over 150 total citations across his key works, Ohnaka’s research bridges engineering and gerontology, creating robots that are not only technically sophisticated but also deeply responsive to human needs.
