Harmony generation system for promoting group exercise motivation

Abstract

In this study, we proposed a harmony generation system to promote motivation for group exercise. The system generates sound based on the user’s movement and enables collaborative music performance by overlaying sounds from multiple individuals. Furthermore, the system supports the creation of harmony by correcting the discrepancies in the timing of sound generation between users. In the exper- iment, the effectiveness of the system was verified by having the participants perform various patterns of exercise with and without sound generation and correction, as well as by changing the degree of correction. The results suggest that engaging in exercise using this system can enhance the user’s motivation for physical activity.
