Breath-based interactions in virtual reality typically map breathing onto discrete visual objects or downstream physiological proxies. Viscereality takes a different approach, mapping lung volume onto a surrounding space composed of particles arranged in an orb enclosing the participant through interoceptive-exteroceptive sensory substitution, such that inhalation expands the environment...
When the brain and body misalign, emotional experience and sense of reality can be disrupted. Although such atypical experiences are central to schizophrenia spectrum disorders (SSD), interoception, processing of internal bodily signals, remains poorly understood in individuals with SSD, particularly across subjective, behavioural, and neural domains. We tested whether SSD is associated with...

Abstract Breath-based interactions in virtual reality typically map breathing onto discrete visual objects or physiological proxies. Viscereality instead translates respiratory state into a surrounding particle field, mapping lung volume onto external space so that inhalation expands the environment and exhalation contracts it. Because particle fields have no fixed boundary, they can convey...
