Abstract
The mouth is one of the most expressive yet least instrumented parts of the body. Tongue and jaw movements carry rich signals for silent speech, assistive interaction, and health monitoring — but capturing them is hard: cameras cannot see inside the mouth, and intra-oral electronics raise comfort, power, and safety concerns.
OralSense enables versatile, accurate oral sensing using small customizable passive magnets. Because the magnets need no battery or electronics and magnetic fields pass freely through tissue, OralSense captures fine-grained oral movements unobtrusively, opening a practical path to in-mouth interaction and health sensing.
Key Contributions
- Passive, customizable magnets require no battery or electronics inside the mouth.
- Magnetic fields pass through tissue, enabling occlusion-free sensing where cameras cannot see.
- Accurate, fine-grained tracking of oral movements for interaction and health applications.
