Towards Emotion-Aware Wearables: Distilling PPG Foundation Models for Real-Time Affective and Physiological Monitoring
Photoplethysmography (PPG) is a physiological signal natively suited for affective computing: non-invasive, continuously acquired from wearables, and directly linked to autonomic responses underlying stress, arousal, and emotional states. Yet deploying high-performance PPG foundation models in real-world settings remai...
