The 2nd Workshop on Eye Tracking Techniques, Applications and Challenges (ETTAC 2026) will be held on August 21, 2026, and is organized in conjunction with ICPR 2026, the 28th International Conference on Pattern Recognition (Lyon, France, August 17-22, 2026).

Eye-tracking technology is becoming increasingly widespread nowadays, also thanks to the recent availability of affordable commercial devices. At the same time, novel techniques are pursued to improve gaze detection precision, and new ways to fully exploit the potential of eye data are continually explored. Whatever the considered use context, whether Human-Computer Interaction, user behavior understanding, biometrics, or others, pattern recognition often plays a significant role.

The purpose of the ETTAC workshop is to present recent eye-tracking research that directly or indirectly exploits pattern recognition. The event’s scope includes (but is not limited to) the following topics:

• Gaze detection techniques
• Gaze-based human-computer interaction (assistive technologies, hybrid interfaces, etc.)
• Eye tracking and AI integration (e.g., combination of gaze and LLMs)
• Eye tracking for usability inspection
• Eye tracking in VR/AR applications
• User behavior understanding from eye data
• Eye movement analysis for biometrics, security, and privacy
• Eye tracking in medicine and health care
• Machine/deep learning for gaze analysis
• Visualization of gaze data

Accepted manuscripts will be included in the ICPR 2026 Workshop Proceedings Springer volume - Lecture Notes in Computer Science (LNCS) Springer series.
