Research on the extension of respiratory interaction modalities in virtual reality technology and innovative methods for healing anxiety disorders.

The timely alleviation and healing of anxiety is crucial for preventing anxiety disorders. This study explores innovative digital approaches for anxiety relief by integrating virtual reality (VR) and multimodal interaction theories and technologies with psychodrama therapy and breathing therapy from psychology. The research proposes an innovative method of breathing interaction based on olfactory interaction modalities and designs breathing interaction semantics aimed at anxiety healing through three types of breathing therapy. Using the Unreal Engine, VR gamified scenarios and interaction logic for levels were constructed, leading to the development of a multimodal immersive software interaction system and a prototype for VR hardware interaction that extends the breathing interaction modality. The effectiveness of the system for anxiety relief was validated through an EEG experiment involving 38 participants, supported by analysis of Topographic Maps, Band-Power Reports, ERP analysis, and qualitative data from the USE scale. This research confirms that the innovative integration of VR and breathing interaction modalities is effective for anxiety therapy, aiding users in promptly alleviating anxiety and simplifying the psychological healing process.
