Self-efficacy estimation for health promotion support with robot partner

Health promotion support systems provide exercise program for elderly people to ensure their health. Some robot partners are used for the system as instructor. In the system, the instructor robot need to select an exercise that improves their health corresponding to the motivation of each person. Our system uses self-efficacy as the motivation index of elderly people for exercise. This paper proposes a self-efficacy estimation method to select more appropriate exercise. This method estimates the self-efficacy based on predicted exercise score acquired through communication and measured score obtained from distance distribution sensor.
