Abstract

A system and method for drowsiness detection by a wearable device (smartwatch or smart ring), which constantly records and processes physiological and behavioral signals combined with historical user data. The system and method actively monitor the user's state, and using signal processing and machine-learning module, detect when the user is entering in a drowsy state. Based on the drowsiness detection module identifying a non-drowsiness an output of a drowsiness detection is directly fed back for future re-evaluation, and based on the drowsiness detection identifying a drowsiness state as being detected, an alert is provided to the user.
