• Modeling Touch Input for Users with Motor Impairments: Empirical Insights into Training Size Requirements

  Radu-Daniel Vatavu, Irina Petrariu, Tudor Horomnea, Ovidiu-Ciprian Ungurean (2026) — Extended Abstracts of the 2026 CHI Conference on Human Factors in Computing Systems (CHI EA ’26)

  This CHI Extended Abstract addresses a practical question for ability-based design: how many touch observations do you actually need before you can build a user-specific model of someone's touch performance? Most touch modeling work, including Bayesi…

• Quantifying Touch: New Metrics for Characterizing What Happens During a Touch

  Junhan Kong, Mingyuan Zhong, James Fogarty, Jacob O. Wobbrock (2022) — Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '22)

  This paper formalizes 15 target-agnostic metrics for characterizing what happens during a touch interaction on a touchscreen, moving beyond the traditional approach of treating touches as simple (x, y) coordinate events. The key insight is that touch…
