How EchoDepth Works
44 facial Action Units. FACS standard. VAD model. Six steps from input to decision intelligence.
Input
EchoDepth receives video input — live feed, recorded session, or uploaded content — from the deployment environment.
Action Unit Detection
EchoDepth detects and classifies 44 facial Action Units in real time using FACS-standard computer vision models.
Cultural Calibration
AU patterns are calibrated against the relevant cultural cohort from EchoDepth's 14-cohort reference set across 6 countries.
VAD Mapping
Calibrated AU patterns are mapped to Valence-Arousal-Dominance coordinates, producing a three-dimensional emotional state output.
Signal Generation
Emotional state data is processed into decision-relevant signals: Trust Score, Credibility Rating, Resistance Indicator, Confidence Score.
Output Delivery
Outputs are delivered via dashboard, API or structured report — formatted for the specific deployment context and governance requirements.
