• 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 a…

• Dialog Generation for Voice Browsing

  Zan Sun, Amanda Stent, I. V. Ramakrishnan (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A): Building the Mobile Web: Rediscovering Accessibility?

  This paper presents HearSay, a voice browser system developed at Stony Brook University that provides speech-driven web access for people with visual disabilities. Unlike conventional screen readers that force users to arrow through a linearized, sin…

• The Meaning of 'Life': Capturing Intent from Web Authors

  Rhys Lewis (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A): Building the Mobile Web: Rediscovering Accessibility?

  This paper explores the fundamental problem that web pages lack explicit semantic information, relying instead on visual cues — layout, color, juxtaposition — to convey meaning. Lewis argues that this semantic deficit creates parallel challenges for …

• Forcing Standardization or Accommodating Diversity? A Framework for Applying the WCAG in the Real World

  Brian Kelly, David Sloan, Lawrie Phipps, Helen Petrie, Fraser Hamilton (2005) — Proceedings of the 2005 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper critically examines how the W3C Web Content Accessibility Guidelines (WCAG 1.0) were being applied in practice six years after their publication, arguing that rigid, context-free application of WCAG was creating serious problems for web de…

• Contextual Web Accessibility - Maximizing the Benefit of Accessibility Guidelines

  David Sloan, Andy Heath, Fraser Hamilton, Brian Kelly, Helen Petrie, Lawrie Phipps (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This influential paper challenges the prevailing approach to web accessibility that treats WCAG conformance as the sole measure of success. The authors argue that while guidelines like WCAG are valuable tools, the persistently low levels of web acces…

  Caroline Jay, Robert Stevens, Mashhuda Glencross, Alan Chalmers (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper uses eye-tracking to investigate a fundamental question about web accessibility: what exactly does visual presentation provide to sighted users that is lost when content is accessed nonvisually (via screen readers) or on small screens? The…

  Philip Ackermann, Carlos A. Velasco, Christopher Power (2012) — Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents a semantic modeling framework for dynamically adapting web 2.0 application interfaces based on user preferences and device capabilities, developed within the EU-funded I2Web (Inclusive Future-Internet Web Services) project. The fr…

  Sarah Horton (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper reframes web accessibility as fundamentally a source code design problem, arguing that designers focus almost exclusively on the visual "surface" of web pages — colors, typography, layouts — while neglecting the underlying code layer that …
