• Evaluation of Assistive Technologies from the perspective of Usability, User Experience and Accessibility: a Systematic Mapping Study

  Tatiany Xavier de Godoi, Guilherme Corredato Guerino, Natasha Malveira C. Valentim · 2021 · Proceedings of the XX Brazilian Symposium on Human Factors in Computing Systems (IHC)

  This systematic mapping study (SMS) investigates how assistive technologies (ATs) are evaluated from the perspectives of usability, user experience (UX), and accessibility — three interrelated but distinct software quality factors. The authors searched Scopus, ACM Digital…

• Web Accessibility Evaluation in a Crowdsourcing-Based System with Expertise-Based Decision Strategy

  Shuyi Song, Jiajun Bu, Ye Wang, Zhi Yu, Andreas Artmeier, Lianjun Dai, Can Wang · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This short paper presents a crowdsourcing-based web accessibility evaluation system that addresses the scalability bottleneck in manual accessibility evaluation: expert evaluators are scarce (training takes years) and expensive, yet many WCAG checkpoints cannot be evaluated…

• Unlocking the Potential of Web Localizers as Contributors to Image Accessibility: What Do Evaluation Tools Have to Offer?

  Silvia Rodríguez Vázquez · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper investigates the role of web localization professionals (translators) in maintaining image accessibility when websites are adapted for different language audiences. The author identifies a significant gap: when websites are localized from one language to another, text…

• Application of Traditional Software Testing Methodologies to Web Accessibility

  Cynthia C. Shelly, Mike Barta · 2010 · Proceedings of the 2010 International Cross Disciplinary Conference on Web Accessibility (W4A)

  Written by authors from Microsoft and the University of Washington, this paper argues that the evolution of web content from static documents to dynamic Rich Internet Applications (RIAs) demands a corresponding evolution in accessibility testing methodology — from post-hoc…

• Quantitative Metrics for Measuring Web Accessibility

  Markel Vigo, Myriam Arrue, Giorgio Brajnik, Raffaella Lomuscio, Julio Abascal · 2007 · Proceedings of the 2007 International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper addresses a fundamental limitation of WCAG conformance levels (A, AA, AAA): they function as binary pass/fail thresholds that cannot distinguish between a site meeting all Priority 1 checkpoints and one meeting all Priority 1 plus nearly all Priority 2 checkpoints —…

• Effects of sampling methods on web accessibility evaluations

  Giorgio Brajnik, Andrea Mulas, Claudia Pitton · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Brajnik, Mulas, and Pitton's Assets '07 paper is a large, careful empirical investigation of the sampling step in web-accessibility evaluation — the step at which an evaluator picks which pages of a site to actually test. For any site above a trivial size, full coverage is…

• SAMBA: a semi-automatic method for measuring barriers of accessibility

  Giorgio Brajnik, Raffaella Lomuscio · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Brajnik and Lomuscio argue that web accessibility cannot be managed without being measured, yet existing accessibility metrics are underdeveloped and almost universally tied to conformance with WCAG checkpoints rather than to the real-world barriers end users encounter. The…

• Semantic Web enabled web accessibility evaluation tools

  Shadi Abou-Zahra · 2005 · Proceedings of the 2005 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper by Shadi Abou-Zahra of the W3C presents the Evaluation and Report Language (EARL) as a Semantic Web-based solution to fundamental problems in web accessibility evaluation tooling. Abou-Zahra identifies that the accessibility evaluation tool market of 2005 provided…
