What NOZA Measures
One short facial video (about 5 seconds) produces two kinds of wellness estimates: video-based vital signals read from subtle skin-tone changes, and image-based facial indicators read from single frames. Every value carries a confidence score, a plain-language explanation, and — for signed-in members — a comparison against your personal baseline.
Video-based vital estimates
Read from the pulse signal in your face across the video (remote photoplethysmography).
Heart-rate estimate
Your pulse in beats per minute (bpm), estimated from micro colour changes in facial skin.
HRV / rhythm stability
How steady your heartbeat rhythm is (ms) — a wellness signal linked to stress and recovery.
Breathing-rate estimate
Breaths per minute, derived from periodic signal changes during the scan.
Oxygen-saturation trend
A relative SpO₂ trend (%) — how your oxygenation moves over time, not a medical-grade oximeter reading.
Pulse-signal strength
How clearly your pulse was detected in this scan — part of every confidence score.
Measurement confidence
Each result reports how reliable this scan was. Low confidence triggers a rescan recommendation instead of a shaky number.
Image-based facial wellness indicators
Estimated from frames of the same capture — appearance-based wellness signals, not measurements of internal physiology.
Facial BMI estimate
A body-mass-index estimate from facial features — a trend indicator for body composition, not a scale replacement.
Facial appearance-age estimate
How old your face appears to the model. An appearance signal that responds to sleep, recovery and lifestyle — not your biological age.
Smoking-related lifestyle-risk indicator
An appearance-based risk estimate associated with smoking and lifestyle factors. An indicator to discuss and track — never a definitive claim about you.
Face & image-quality confidence
Lighting, stillness and framing are scored on every scan; poor quality lowers confidence and can mark results unavailable.
Every measurement includes
- A value with its unit — plus an explicit “unavailable” state when scan quality is too low to be honest.
- A confidence score, so you always know how much to trust this scan.
- A plain-language explanation of what the number means for wellbeing.
- Your personal baseline comparison, once you have a few scans in Progress Mode.
- A wellness-screening disclaimer — these are estimates for self-knowledge, not diagnoses.
