Auracle: A Fitbit for Your Mouth  

 

Clemson and Dartmouth Colleges wanted help in their execution of an ergonomic head wearable for research. The goal is to develop a device — that can automatically sense, detect, and track actions such as eating, drinking, smoking, speaking, and can measure physiological stress. The device will help health-science researchers in their efforts to study eating behavior.

The bone surfaces around the ear vibrate at different frequencies depending on whether there is a eating, drinking, smoking, speaking, or a breathing event. A contact microphone placed next to the skin (pressed against the bone) can identify those vibrations and sounds. Using machine learning algorithms and code, the vibrations and sounds can be classified and categorized in real time, accurately tracking events.
