EarMag: In-Ear Sensors for Hands-Free Interaction via Jaw and Head Movements

What is it about?

This study explores a new way to detect jaw and head movements using small sensors worn inside the ear, called EarMag. Unlike cameras or microphones, this approach works discreetly from within the ear and does not rely on sound or vision. EarMag was tested by recording a wide range of jaw and head exercises from multiple participants and examining whether different movements could be distinguished. While individual anatomical differences make this challenging, the findings show that EarMag can capture meaningful movement information. This work highlights the potential of EarMag for hands-free interaction, assistive technologies, silent communication, and long-term monitoring of body signals.
