Luminarsphere™ operates a deployable platform for measuring group psychophysiology in real venues — yoga and breathwork studios, sound baths, and immersive domes. We work with academic investigators who want to study collective states outside the laboratory.
The system captures photoplethysmography (PPG) simultaneously from every participant in a room via wrist-worn Molaband™ units, streams inter-beat intervals to a local compute node, and derives heart-rate-variability measures per participant and per group in real time. Sessions are stored in Neural Bank™, our session database.
A pre-registered study of group states in an immersive dome environment is currently underway, with a statistical analysis plan finalized before data collection and an independent statistician responsible for the analysis. Co-primary endpoints are convergence (C_score™) and synchrony (ISC), which we treat as distinct constructs rather than interchangeable measures — dispersion at an instant versus co-movement over time. Results will be reported whatever the direction of the findings. Methods documentation is available to collaborating investigators on request.
Our measures and study design are reviewed by advisors with published expertise in the fields our work draws on.
Advises on HRV and biofeedback methodology, our coherence-scoring approach and its validation, research design, and session safety.
Advises on clinical and technology-assisted behavioural health research, immersive environment design, and translation of measurement into applied settings.
Advisors serve in a personal capacity. Their institutional affiliations are listed for identification only and do not imply institutional endorsement of Luminarsphere™.
Our participant- and venue-facing materials use wellness language and describe how a session shifted across a measurement window. We do not make clinical or diagnostic claims, and we do not describe our group measures as validated markers of any psychological construct beyond what the data support.
We try to be precise about what is established and what is ours. The signal is validated — our hardware was bench-validated against a clinical-grade ECG reference. ISC is an established method with published use in shared-stimulus group settings; what is novel is our real-time room-scale application of it. C_score™ is our own metric — a patent-pending operationalisation resting on peer-reviewed foundations, but not itself independently validated. Where a finding is early-stage, we say so. Investigators who find our framing overstated anywhere are invited to tell us — that feedback has already changed how we report.
Our methods are reviewed by the Scientific Advisory Board named below. Core measurement methods are covered by a filed U.S. provisional patent; the C_score™ formula is disclosed to collaborating investigators under confidentiality so that methods can be properly reviewed.
Tell us about your research question and what you would need to measure. We respond to academic inquiries directly, and early-stage conversations are welcome — including ones that conclude the platform is not the right fit.
