YOUBLUE

This study aims to explore human perceptions towards a robotic
biofeedback system designed to support emotion regulation for
non-clinical populations. We developed and implemented YOUBLUE,

a robot-based emotion regulation system driven by breathing and heartbeat signals. Unlike traditional screen-based or wearable biofeedback systems, the proposed system employs an embodied robot to deliver perceivable biofeedback, enabling users to become aware of
their physiological states and actively regulate them in a more natural and immersive way. 

 

Through this mechanism, users’ internal physiological signals are externalized and embodied as expressive responses, fostering a self-empowering experience of emotion regulation. Furthermore, this study investigates how the robot’s appearance influences users’ perceptions and acceptance to evaluate whether robotic embodied biofeedback can serve as a medium that enhances user engagement and psychological connectedness in emotion regulation processes.
