Affective biometrics constitutes a subfield of computing that uses physiological data indicating affect or emotion to identify – or predict – a person’s identity or behavior.
“Affect is often shown in the human body’s physical reaction to emotion,” said Washington. “We typically associate this with facial expressions, but affect, within the context of biometrics, also encompasses body language, physical gestures and even the human autonomic system through measurable data focusing on things like heart rate, blood pressure and even sweating.” – IEEE Member Gloria Washington
