Necklace Tracks Food Intake by Analyzing Chewing Sounds
From: Medical Design Technology - 03/16/2017

University at Buffalo computer scientist Wenyao Xu is creating a library that
catalogues the unique sounds that foods make as we bite, grind and swallow
them.

The library is part of a software package that supports AutoDietary, a
high-tech, food-tracking necklace being developed by Xu and researchers at
Northeastern University in China.

AutoDietary wraps around the back of the neck like a choker necklace. A tiny
high-fidelity microphone - about the size of a zipper pull - records the
sounds made during mastication and as the food is swallowed. That data is
sent to a smartphone via Bluetooth, where food types are recognized.
