Slippage of head-worn glasses during real-world behavior: an examination, dataset and testing protocol
This paper investigates the slippage of head-worn glasses and eye trackers during everyday activities, a critical factor affecting gaze estimation accuracy. Using motion capture data from 35 participants performing 10 tasks, it quantifies slippage (0.26-4.05 mm, 0.10-1.81 deg). The study finds no significant difference in slippage between smart glasses and eye trackers but identifies task-specific variations. A key outcome is a proposed three-task testing battery designed to approximate real-world slippage, aiming to guide robust wearable eye tracker design for daily life integration. The dataset is made publicly available for further research.
Executive Impact at a Glance
Wearable eye trackers and smart glasses frequently experience slippage during daily activities, significantly impacting data accuracy. Our research quantifies this movement, finding an average slippage of 0.26-4.05 mm and 0.10-1.81 degrees across various tasks. Crucially, we found no significant difference in slippage between dedicated eye trackers and consumer-grade smart glasses. To mitigate this, we propose a new, simplified three-task testing protocol that accurately simulates real-world slippage. Implementing this protocol will enable manufacturers to design more robust devices, reducing data loss and improving user experience. This translates directly to enhanced reliability for enterprise applications relying on eye-tracking data, such as human-computer interaction research, training simulations, and retail analytics, ultimately safeguarding data integrity and accelerating innovation.

Impact on Gaze Accuracy in Real-World Scenarios
Previous work by Niehorster et al. (2020a) and Hooge et al. (2023) has shown that even small amounts of slippage (0.8-3.1°) can lead to significant gaze estimation errors and data loss. This study's findings on slippage magnitude reinforce the need for robust eye-tracking systems capable of compensating for these movements.
Slippage leads to errors up to 5.8° during jumping.
