• A declarative model for accessibility requirements

  Jens Pelzetter · 2020 · Proceedings of the 17th International Web for All Conference (W4A)

  This paper addresses a fundamental problem in automated accessibility testing: different tools produce inconsistent results because they each implement their own interpretation of WCAG guidelines in code, and the guidelines themselves contain ambiguity. The author proposes a…

• Modelling web navigation with the user in mind

  Ruslan Fayzrakhmanov, Max Göbel, Wolfgang Holzinger, Bernhard Krüpl, Andreas Mager, Robert Baumgartner · 2010 · Proceedings of the 2010 International Cross Disciplinary Conference on Web Accessibility (W4A)

  This paper introduces the ABBA (Advanced Barrier-free Browser Accessibility) framework, a novel approach to screen reader design that replaces traditional sequential DOM-based navigation with a multi-axial navigation model. The core insight is that current screen readers force…

• The Impact of Accessibility Assessment in Macro Scale Universal Usability Studies of the Web

  Rui Lopes, Luís Carriço · 2008 · Proceedings of the 2008 International Cross-Disciplinary Conference on Web Accessibility (W4A 2008)

  This paper introduces Web Interaction Environments (WIEs), a modelling framework for studying universal usability of the web at large scale. The authors argue that existing approaches to accessibility evaluation treat audiences as homogeneous groups, failing to capture the…

• A user evaluation of the SADIe transcoder

  Darren Lunn, Sean Bechhofer, Simon Harper · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper presents a user evaluation of SADIe (Structural-Semantics for Accessibility and Device Independence), a system that uses Semantic Web technologies to make web pages more accessible to screen reader users. The core problem SADIe addresses is that web pages convey…

• Semantic Bookmarking for Non-Visual Web Access

  Saikat Mukherjee, I. V. Ramakrishnan, Michael Kifer · 2004 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets 04)

  This paper introduces semantic bookmarking, a technique for non-visual web access that allows blind users to bookmark meaningful content segments on web pages using domain ontologies rather than structural HTML positions. The research is built on HearSay, a speech-driven…
