Abstract
Techniques to detect a non-alert state of a user may include receiving sensor data from an ear-worn electronic device disposed at least partially in the ear of a user, determining an alertness state of the user based on the sensor data, and providing alert data in response to the alertness state comprising a non-alert state to a user stimulation interface of the ear-worn electronic device or to an external device.
