Abstract
The market for wearable devices that measure heart rate has been expanding in recent years, and many health management and lifelogging products have been released. However, there is still room for development in the application of wearable devices in the entertainment field. This led us to create heartbeat, an entertainment system that utilizes changes in heart rate and is fun for everyone to use. Working with their own heartbeat, which cannot be controlled completely through willpower, users can enjoy the appropriate exercise benefits while enjoying a game-like experience.
