HeadGaze: Natural Gaze Estimation While Walking From a Single IMU on Earbuds

Gaze provides valuable insights into people’s interests and can facilitate seamless interaction with computational systems. However, capturing natural gaze during dynamic motions with compact, low-cost, low-power wearables like earbuds is challenging. While gaze estimation using IMUs has been explored, it typically requires the user to remain still or relies on additional data such as posture, limiting its use in various scenarios. In this work, we propose HeadGaze, which estimates gaze also in
