The system begins not with language, but with the quiet signals the body transmits — involuntarily, continuously, truthfully.
Overview
Participants wear non-invasive biometric sensors that capture subtle physiological signals in real time. Heart rate variability. Respiration rhythm. Neural oscillations. Electrodermal response.
These signals are not read as data about individuals — they are received as the raw material of collective experience. The sensing layer is the system's ear: wide, patient, free from interpretation.
What the sensors read
The fluctuation in time between heartbeats — a window into autonomic nervous system state, stress, and restorative capacity. In the collective, HRV alignment marks moments of physiological convergence.
Alpha and beta wave ratios reveal attentional state, emotional valence, and cognitive engagement. Shifts in group-wide neural patterns signal shared attention or collective drift.
Breath rate and depth shape the harmonic texture of the sound environment. Group breath synchrony — often unintentional — is one of the most powerful signals of collective cohesion.
Skin conductance traces emotional arousal with remarkable sensitivity. Micro-surges across participants indicate shared emotional peaks — moments of collective attention or resonance.
Subtle postural shifts and kinetic energy contribute to arousal calculation. Movement is the most visible layer of inner state — and the easiest to read across a group.
Together, these signals form a physiological portrait of the group's inner landscape.
"These signals are held collectively, not interpreted individually — the sensing layer has no interest in who you are, only in what we are, together."Emphonic System — Design Principle
Signal integrity
When inputs become noisy or ambiguous — due to movement, hardware contact, or environmental interference — the system flags and compensates rather than proceeding on corrupted data.
Signal quality assessment runs in real time. Channels are individually weighted; degraded inputs reduce in influence without breaking the collective state. The system favors graceful handling over brittle precision.
Privacy is structural, not procedural. Raw biometric data is never stored in identifiable form. Individual participant profiles are never built. The system listens, processes, and releases — leaving no trace of who was sensed, only what was felt.
