We propose a novel interface for human-computer interactions that enables breathing actions. Our method aims to use commercial off-the-shelf microphones to detect inhalation and exhalation actions through real-time sound processing and AI. We wish to map the detected expressions to different parameters in virtual environments and XR, for meditation, relieving stress, relaxing, and mindfulness. Furthermore, we believe our method can become a multi-user experience to form a strong sense of harmony.
