PACMHCI V9, N3, May 2025 Editorial

This special issue of the Proceedings of the ACM on Human-Computer Interaction includes accepted full papers from the ACM Symposium on Eye Tracking Research and Applications (ETRA). ETRA is the premier eye-tracking conference that brings together researchers from across disciplines to present advances in eye-tracking systems and methods, oculomotor research, eye movement data analysis, gaze-based interaction, and eye-tracking applications. A total of 24 full papers were accepted from 80 submissions after a rigorous reviewing process (30% acceptance rate). Accepted contributions were split into special issues in two journals, depending on the fit of topic and authors' preferences. 16 accepted papers are included in this issue of the Proceedings of the ACM on Human-Computer Interaction. 8 will be published in the Proceedings of the ACM on Computer Graphics and Interactive Techniques. All accepted papers are invited to present at ETRA 2025 (May 26 - May 29, 2025, in Tokyo). We would like to thank all members of the Editorial Board and all external reviewers for their effort and dedication, as well as all authors for their high-quality contributions.
