  bibo_abstract:
  - Heart rate variability biofeedback has emerged as a validated intervention for
    stress management and emotional regulation through coherence breathing techniques.
    Existing biofeedback systems typically present cardiac and respiratory signals
    as separate feedback channels or rely on discrete interface elements that fragment
    attention and disrupt immersion. We present a design framework that extends Viscereality,
    a bioresponsive VR framework originally developed for breath mapping, to integrate
    multi-channel biofeedback including heart rate within immersive VR, centered on
    a particle-based environment that functions as a spatial body-mapping interface.
    By leveraging bioresponsive breath interactions for embodiment and weak representational
    aesthetics for cardiac coherence, the framework aims to encode both streams within
    a shared visual substrate, reducing the attentional task-switching and experiential
    fragmentation that multi-channel displays otherwise risk. The system translates
    lung volume into spatial expansion and contraction of the environment itself,
    maps cardiac coherence onto affective visual dimensions (angularity, brightness,
    saturation, symmetry), and embeds breathing guidance within the same geometric
    substrate. We present the design rationale and implementation of this framework,
    with empirical validation of its effectiveness to be conducted in future studies.@eng
