Towards In-Ear Inertial Jaw Clenching Detection

Published: 17 February 2020 Publication History

Abstract

Bruxism is a jaw-muscle condition characterized by repetitive clenching or grinding of teeth. Existing methods of detecting jaw clenching towards diagnosing bruxism are either invasive or not very reliable. As a first step towards building a reliable, non-invasive and light weight bruxism detector, we propose an eSense based in-ear inertial jaw clenching detection technique that detects peaks/dips in gyroscope vector magnitude. We also present results from preliminary experiments that show an equal error rate of 1% when the person is stationary and 4% when moving.
