Intelligent Wellness Glossary.

An intelligent wellness platform and personal companion that empowers individuals and families with contextual, preventive guidance using optical camera vitals, circadian chronobiology, and habit check-ins with complete data privacy.

A proactive health paradigm combining multimodal biological signals (contactless camera vitals, wearables, chronobiology) with contextual AI to predict energy patterns and encourage healthy daily micro-habits.

An optical camera-based technique that measures cardiovascular pulse waveforms by detecting minute, microscopic color variations in ambient light reflected from facial microvascular skin beds.

The variation in time intervals between consecutive heartbeats (Root Mean Square of Successive Differences). A key biomarker of parasympathetic nervous system tone, recovery, and stress resilience.

The endogenous ~24-hour biological oscillation governing sleep-wake cycles, cortisol awakening surges, core body temperature, and metabolic energy peaks.

A conscious breathing rate of approximately 6 breaths per minute (~0.1 Hz) that synchronizes heart rate variability with respiratory sinus arrhythmia to stimulate vagal tone and induce calm.

A mathematical privacy standard ensuring that individual health records in an aggregate dataset cannot be distinguished from at least k-1 other individuals within the same cohort.
