• The Crowd Work Accessibility Problem

  Saiganesh Swaminathan, Kotaro Hara, Jeffrey P. Bigham · 2017 · Proceedings of the 14th International Web for All Conference (W4A)

  This paper examines a largely overlooked accessibility problem: the inaccessibility of crowdsourcing tasks themselves. While crowd work platforms like Amazon Mechanical Turk (AMT) offer potential employment benefits for people with disabilities — flexible scheduling, remote…

• Measuring and comparing the reliability of the structured walkthrough evaluation method with novices and experts

  Christopher Bailey, Elaine Pearson, Voula Gkatzidou · 2014 · Proceedings of the 11th Web for All Conference (W4A)

  This paper investigates the reliability of the Structured Walkthrough evaluation method — a systematic approach to manual accessibility evaluation embedded in the Accessibility Evaluation Assistant (AEA) tool. The AEA contains 48 accessibility heuristics organised into five…

• Three web accessibility evaluation perspectives for RIA

  Nádia Fernandes, Ana Sofia Batista, Daniel Costa, Carlos Duarte, Luís Carriço · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents a large-scale comparative study of web accessibility evaluation across three distinct perspectives that reflect how Rich Internet Applications (RIAs) are actually experienced by users. The three evaluation perspectives are: E1, evaluating the raw HTML before…

• Automatic accessibility evaluation of dynamic web pages generated through XSLT

  André Pimenta Freire, Renata Pontin de Mattos Fortes · 2005 · Proceedings of the 2005 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper from researchers at the University of São Paulo addresses a gap in accessibility evaluation tooling: the inability of automated checkers to test dynamically generated web pages. In 2005, tools like Bobby, LIFT, and WAVE could only evaluate static HTML output — meaning…

• Proving the validity and accessibility of dynamic web-pages

  R. G. Stone, J. Dhiensa · 2004 · Proceedings of the 2004 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper from Loughborough University proposes a formal verification approach to proving that dynamically generated web pages will always produce valid and accessible output, regardless of which code path executes at runtime. The authors draw a direct analogy to program…
