  text: 'We introduce a bioresponsive virtual reality system that maps users'' breathing
    patterns to dynamic, spatialized visual feedback. The system implements Gestalt
    principles, such as good figure, similarity, and symmetry, within a 3D particle-based
    environment to enhance the embodiment of interoceptive and exteroceptive space,
    aiming to blur the subjective boundary between bodily self and the external virtual
    space. Moreover, the system incorporates coupling kernels within a dynamic system
    composed of Kuramoto oscillators, enabling the emergence of geometric visual symmetries
    during breath retention phases. This architecture provides an experimental framework
    for investigating how visual–respiratory coupling of space can influence perceived
    bodily boundaries and peripersonal space, as well as for testing how such coupling
    affects positively valenced aspects of subjective experience, drawing on principles
    from the Symmetry Theory of Valence. A short video summary of the system is available
