What Is Group HRV —
and Why It Matters

A plain-language guide for guests, partners, and press.

"Every yoga teacher knows when a class lands. Until now, no one could show it."

01 / Definition

What is heart rate variability?

Heart rate variability — HRV — is the natural, healthy variation between consecutive heartbeats. Your heart does not beat like a metronome. The intervals between beats expand and contract, breath by breath, in response to whatever your nervous system is doing.

When you are calm, regulated, and present, those intervals vary widely — a sign of a flexible, well-tuned autonomic nervous system. When you are stressed, exhausted, or dysregulated, the variation collapses. The signal flattens.

HRV has been studied for decades as one of the most reliable biomarkers of nervous-system state available outside a clinic. Whoop, Oura, Apple Watch, and Garmin have all built consumer products around it. What none of them measure is what happens when a group of people share an experience.

02 / The new thing

Group HRV is what we measure that no one else does.

An individual HRV reading tells you about one nervous system at one moment. Group HRV tells you what is happening to a room of nervous systems together — and how that pattern moves over the course of an experience.

🧘

A yoga class

75 minutes

Did the room actually settle into savasana? Did the energy lift in vinyasa? When did the group find its breath together? These are the questions instructors have always answered with intuition. Group HRV answers them with data.

🌌

An immersive experience

live

Which moments in a fulldome show actually move the audience? Where does attention peak? Where does the room hold its breath, and where does it exhale together? Group HRV makes the invisible architecture of an experience visible.

🧠

A community health event

research-grade

Which parts of an education session land for the people most affected? When does engagement deepen? What patterns emerge across patient cohorts that traditional satisfaction surveys miss? Group HRV adds a layer of evidence research has never had.

🧒

A neurodiverse cohort

attentional

When children with sensory differences regulate together — when does it happen, and what allowed it? Group HRV gives educators, therapists, and researchers a measurable signal where before they had only behavioural observation.

"Whoop owns the wrist. Oura owns the ring. Luminarsphere™ owns the room."

03 / Method

How we measure it.

Three layers, working together in real time, anywhere a group meets:

L1

Molaband™ — the wearable

A venue-issued wristband worn by each guest. Captures pulse-wave data and computes inter-beat intervals at the wrist. Validated against the Polar H10 ECG — the clinical gold standard for HRV measurement — within a mean error of 1.27 BPM. No app required. No account required. Returned at the end of the session.

L2

NeuralPulse Engine™ — the real-time computer

Edge-deployed signal-processing engine. Streams data from up to 200 wristbands simultaneously and computes a proprietary group coherence score (C_score™) in real time, validated against Dr. Cynthia Kerson's published BCB-HRV biofeedback standard. Runs on local hardware — your data never leaves the venue without you knowing.

L3

Group Audience Response Report™ — the deliverable

A presentation-grade PDF generated for the operator at the end of every session. Group coherence trajectory, peak moments, entry-to-exit nervous-system delta, and timestamped notes on what the room did and when. The first time in history a yoga studio, fulldome, or research event has had this kind of report.

04 / Privacy by Architecture

Anonymous by design — not by promise.

Most "anonymous" data products promise anonymity at the policy layer and rely on you to trust them. We engineered anonymity into the architecture. There is no mechanism in our system that captures personal identity, even if we wanted one.

What we collect

  • · Anonymous device identifiers
  • · Inter-beat intervals from the wrist
  • · Session timestamps
  • · Group-level computed metrics

What we do not collect

  • · No names, no emails, no phone numbers
  • · No personally identifiable information (PII)
  • · No protected health information (PHI)
  • · No location, no biometrics that could re-identify

Each Molaband™ is venue-issued and venue-retained. Guests who want their own data receive an opt-in session token at the end — a one-time link to view their own report, never linked to an account or email address.

This architecture is what makes Luminarsphere™ deployable in settings where privacy is not optional: clinical research, community health programmes, neurodiverse cohorts, and any space where consent and dignity must be designed in, not bolted on.

05 / The artifact

What the Group Audience Response Report™ shows.

One presentation-grade PDF, delivered after every session.

The report shows where the group's nervous system was at entry, how it shifted across the experience, where peak coherence occurred, and what the entry-to-exit delta looked like for the room as a whole. For an instructor, it is the first time the unspoken rhythm of a class has been put on paper. For a researcher, it is a measurable layer of engagement that traditional surveys cannot reach.

"After 24 years of teaching, this is the first time I've seen what I've always felt."
