Body Cosmos 2.0: embodied biofeedback interface for dancing.

This study presents Body Cosmos 2.0, an embodied biofeedback system with an interactive interface situated at the intersection of dance, human-computer interaction, and bio-art. Building on the authors' prior work, "Body Cosmos: An Immersive Experience Driven by Real-time Bio-data," the system presents the concept of a 'bio-body'-a dynamic digital embodiment of a dancer's internal state-generated in real-time through electroencephalography, heart rate sensors, motion tracking, and visualization techniques. Dancers interact with the system through three distinct experiences "VR embodiment," which enables them to experience their internal states from a first-person perspective; "dancing within your bio-body," which immerses them in their internal physiological and emotional states; and "dancing with your bio-body," which creates a bio-digital reflection for expressive development and experiential exploration. To evaluate the system's effectiveness, a workshop was conducted with 24 experienced dancers to assess its impact on self-awareness, creativity, and dance expressions. This integration of biodata with artistic expression transcends traditional neurofeedback and delves into the realm of embodied cognition. The study explores the concept, development, and application of "Body Cosmos 2.0," highlighting its potential to amplify self-awareness, augment performance, and expand the expressive and creative possibilities of dance.
