Description
HealthRing RingDatasetV2.1 is a comprehensive ring‑based physiology dataset designed to advance reliable cardiovascular sensing on finger‑worn devices. It contains three synchronized cohorts from 54 adults: Study 1 (scripted physiological stimuli), Study 2 (semi–free‑living daily activities), and Study 3 (motion‑intensive treadmill running). Two custom rings (reflective and transmissive) record infrared/red PPG and 3‑axis accelerometer signals at 100 Hz; reference labels include clinical‑grade HR, RR, SpO₂, and BP for Study 1/2, plus treadmill ECG (128 Hz/100 Hz) with ECG‑derived HR/RR for Study 3. Data are released as windowed 30‑s segments in per‑participant tables with a consistent schema (placeholders retained for compatibility). The dataset targets reproducible benchmarking and algorithm development across controlled, daily‑life, and high‑motion scenarios, enabling robust evaluation of ring‑based vital‑sign estimation.
