Oxygen Saturation
SpO2 estimated from video, adding a physiological channel that is hard to fake convincingly.
Oxygen saturation estimation (SpO2) reflects emotional states: happiness shows stable levels with mild rise during laughter; anger causes sudden drops and erratic shifts; sadness maintains slightly reduced consistency; surprise results in brief dips; fear leads to irregular, declining patterns; and disgust reveals fluctuating levels with delayed stabilization.
Oxygen Saturation is one of eight signals used by the Trust Factor Engine. It is considered alongside the other seven rather than being treated as the only basis for the overall result. A single signal does not independently determine the final verdict. How the weighting works
