• 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…

• Adults with High-functioning Autism Process Web Pages With Similar Accuracy but Higher Cognitive Effort Compared to Controls

  Victoria Yaneva, Le An Ha, Sukru Eraslan, Yeliz Yesilada · 2019 · Proceedings of the 16th International Web for All Conference (W4A)

  This paper investigates the accuracy and efficiency with which adults with high-functioning autism process web pages compared to neurotypical controls, using eye-tracking to reveal hidden cognitive effort differences. The study addresses a critical gap: existing web…

• It's All About the Message: Visual Experience is a Precursor to Accurate Auditory Interaction

  Simon Harper, Sukru Eraslan, Yeliz Yesilada · 2019 · Proceedings of the 16th International Web for All Conference (W4A)

  This paper argues that understanding how sighted users visually experience web pages is a necessary precursor to designing effective auditory (screen reader) experiences for visually disabled users. The authors challenge the assumption that the experiences of sighted and blind…
