GrooveMeter: Enabling Music Engagement-aware Apps by Detecting Reactions to Daily Music Listening via Earable Sensing

摘要

We present GrooveMeter, a novel system that automatically detects vocal and motion reactions to music and supports music engagement-aware applications. We use smart earbuds as sensing devices, already widely used for music listening, and devise reaction detection techniques by leveraging an inertial measurement unit (IMU) and a microphone on earbuds. To explore reactions in daily music-listening situations, we collect the first-kind-of dataset containing 926-minute-long IMU and audio data with 30 participants. With the dataset, we discover unique challenges in detecting music-listening reactions and devise sophisticated processing pipelines to enable accurate and efficient detection. Our comprehensive evaluation shows GrooveMeter achieves the macro F1 scores of 0.89 for vocal reaction and 0.81 for motion reaction with leave-one-subject-out (LOSO) cross-validation (CV). More importantly, it shows higher accuracy and robustness compared to alternative methods. We also present the potential use cases.
