Robot-human interaction to encourage voluntary action

This paper discusses robot partner interaction based on Frankl's psychology to encourage a person act voluntarily. Recently, elderly people who live alone in a room is increased. But, it is hoped that the elderly people keep good health. To keep good health for elderly people, a person should act voluntarily and get involved in community events. In Frankl's psychology insists that the meaning of life is required from external stimuli. Frankl's psychology is defined 3 fields of value which are provided from external stimuli. A person can be found the meaning of life according to the values getting. Therefore, it is expected that a person would act voluntarily if a person find the meaning and value of life from external stimuli through interacting with a robot partner. In this research, we propose the robot interaction method based on Frankl's psychology. And we propose an external value estimation method based on the fields of value which estimates an external value from environmental change. Through human-robot interaction experiment based on Frankl's psychology, we verify that a human acts voluntarily by finding the external value.
