Abstract
A wearable device for detecting a user state is disclosed. The wearable device includes an accelerometer for measuring an acceleration of a user, a magnetometer for measuring a magnetic field associated with the user's change of orientation, a microphone for receiving audio, a memory for storing the audio, and at least one processor communicatively connected to the accelerometer, the magnetometer, the microphone, and the memory. The processor is identified to declare a measured acceleration as a suspected user state, and to categorize the suspected user state based on the stored audio as one of an activity of daily life (ADL), a confirmed user state, or an inconclusive event.
