• Find and Seek: Assessing the Impact of Table Navigation on Information Look-up with a Screen Reader

  Kristin Williams, Taylor Clarke, Steve Gardiner, John Zimmerman, Anthony Tomasic · 2019 · ACM Transactions on Accessible Computing (TACCESS)

  This paper challenges the widely held assumption that HTML tables are inherently inaccessible to screen reader users. Web designers use visual cues like layout, typography, and spatial grouping to help sighted users navigate and understand page content, but screen readers…

• X-Ray: Screenshot Accessibility via Embedded Metadata

  Sujeath Pareddy, Anhong Guo, Jeffrey P. Bigham · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper introduces X-Ray, a system that preserves the accessibility of user interface content when it is captured as a screenshot. Screenshots strip away all semantic information — text structure, element roles, states, labels, and navigation order — leaving only pixels that…

• The Design Space of Nonvisual Word Completion

  Hugo Nicolau, Andre Rodrigues, Andre Santos, Tiago Guerreiro, Kyle Montague, Joao Guerreiro · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper presents the first design space for nonvisual word completion on mobile devices, addressing a gap where word completion interfaces — ubiquitous in sighted mobile typing — remain poorly designed for screen reader users. While sighted users can glance at three…
