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.","lang":"eng"}],"language":[{"iso":"eng"}],"oa":"1","file_date_updated":"2026-09-16T08:24:45Z","keyword":["heart rate variability","biofeedback","virtual reality","affective state modulation","affective visualization","coherence breathing"],"title":"Breathing Space: Spatial Mapping of Breath and Cardiac Biofeedback for Affective State Representation and Coherence Training in Viscereality","project":[{"_id":"A827C0AA-C7DA-11E9-B0AE-1F4CB252D58D","name":"Institute for Building Intelligence"}],"quality_controlled":"1","place":"New York, NY, USA","year":"2026","has_accepted_license":"1","publisher":"ACM"}
