Applying “Earable” Inertial Sensing for Real-time Head Posture Detection

We explore the use of personal earable devices for detecting and correcting incorrect head postures, which can trigger the medical condition of “Forward Head Posture”. We demonstrate how the gyroscope and accelerometer sensors on an earable device can be used to detect episodes where the head is rotated sufficiently forward, for significantly long durations (> 30secs), and then generate suitable audio-based corrective feedback. Using a small-scale preliminary study, we show that our approach is promising as it provides both high precision (100%) & recall (89%).
