contactless rppg spatial health auditing: micro zone biometric profiling of historic built environments in coventry

Executive Abstract: This study presents a venue-centric biometric field audit quantifying autonomic nervous system
(ANS) responses across historic heritage micro-zones and urban street thresholds in Coventry, UK. Utilizing contactless
Remote Photoplethysmography (rPPG), real-time Heart Rate Variability (ΔHRV) and Heart Rate (ΔHR) shifts were recorded
across 10 locations. Results demonstrate a reproducible physiological contrast: timbered historic enclosures act as
salutogenic (restorative) anchors (HRV up to 132 ms, HR down to 53 BPM), whereas step-out urban street edges induce
acute sympathetic stress (HRV collapsing to 54 ms, HR spiking to 107 BPM).
