• Typing Performance of Blind Users: An Analysis of Touch Behaviors, Learning Effect, and In-Situ Usage

  Hugo Nicolau, Kyle Montague, Tiago Guerreiro, André Rodrigues, Vicki L. Hanson · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This longitudinal study provides the most detailed analysis to date of how novice blind users learn to type on touchscreen keyboards using the Explore by Touch paradigm (where users slide fingers across the screen to hear key names, then lift to select). Five legally blind…

• A Unifying Notification System To Scale Up Assistive Services

  Charles Consel, Lucile Dupuy, Hélène Sauzéon · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper addresses a fundamental scalability problem in assistive technology for older adults: the "silo-based" approach where each assistive service (pill reminders, door monitors, activity trackers) implements its own notification system. When older adults need multiple…
