Human-robot interaction based on cognitive bias to increase motivation for daily exercise

摘要

Aging society in Japan can be a big serious problem. However, the number of caregivers is currently not enough, and it is not expected to sufficiently increase in future. Elderly care has been shifting from hospital care to community-based care and home care, but this can lead to raise the burden on their family members. Therefore, elderly people should take care of their heath in daily life in order to prevent mental and physical depression. This paper presents a daily exercise support system with a robot partner utilized as an exercise instructor. We discuss the robot human-robot interaction in terms of framing effect. The framing effect is an example of cognitive bias that influences someone's choice depending on whether it is presented as a positive thing or as a negative thing. Here, we implemented verbal communication contents base on positive frame or negative frame. Furthermore, we conducted a demonstration experiment to examine the effect of each expression on elderlies' motivation.
