JawSense is a wearable device that enables interaction with a computing machine based on unvoiced jaw movement tracking. Speech and touch-typing are the two most common input modalities for smart devices [5]. However, they pose challenges in many scenarios where touch-typing restricts hands-free operation and speech commands are not desirable [1]. JawSense offers a novel sensing modality through unvoiced jaw movement tracking. It is hands-free, socially acceptable, privacy-preserving, and an intuitive input sensing modality. In addition to jaw movements, accelerometer measurements can be affected by body movements and mechanical waves (music) from external sources vibrating the system.
