• Physical Usability and the Mobile Web

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

  This paper systematically compares the physical usability challenges faced by desktop web users with motor impairments and mobile web users, identifying where their needs overlap and diverge. Trewin first catalogs the interaction landscape for users …

• Do Text Transcoders Improve Usability for Disabled Users?

  Giorgio Brajnik, Daniela Cancila, Daniela Nicoli, Mery Pignatelli (2005) — Proceedings of the 2005 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper presents the first scientific user study examining whether text transcoders — proxy-based systems that dynamically transform web pages into text-only versions — actually improve usability for disabled users. Text transcoders strip images, …

• Interdependent Components of Web Accessibility

  Wendy A. Chisholm, Shawn Lawton Henry (2005) — Proceedings of the 2005 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  Written by two key members of the W3C Web Accessibility Initiative (WAI), this paper provides the definitive explanation of how web accessibility depends on multiple interdependent components working together — a systems view that was often overlooke…

• Web Presentation Layer Bootstrapping for Accessibility and Performance

  Clint Andrew Hall (2009) — Proceedings of the 2009 International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper presents the "Web Bootstrapper," a technique for delivering different presentation experiences ("skins") from a single semantic HTML codebase without altering source markup or running costly client-side detection code. The approach address…

• Designing for Auditory Web Access: Accessibility and Cellphone Users

  Shari Trewin, Rachel Bellamy, John Thomas, Jonathan Brezin, John Richards, Cal Swart, Bonnie E. John (2010) — Proceedings of the 2010 International Cross Disciplinary Conference on Web Accessibility (W4A)

  This paper draws a parallel between two groups of web users who experience the web primarily through auditory rather than visual interaction: people with visual impairments using screen readers, and people in developing regions accessing the web thro…

• Evaluating Interfaces for Intelligent Mobile Search

  Karen Church, Barry Smyth, Mark T. Keane (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper argues that simply transplanting desktop web search interfaces onto mobile devices creates a poor user experience, and proposes an alternative approach to presenting search results on small screens. The authors first evaluate seven mobile …

• A Macroscopic Web Accessibility Evaluation at Different Processing Phases

  Nádia Fernandes, Luís Carriço (2012) — Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper investigates a fundamental question about automated accessibility evaluation: does it matter whether you evaluate a web page as it arrives from the server (before browser processing) or as the user actually experiences it (after browser pr…

• Age and Web Access: The Next Generation

  Vicki L. Hanson (2009) — Proceedings of the 2009 International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper challenges the common assumption that technology difficulties experienced by older adults are a fixed characteristic of aging that will naturally disappear as tech-savvy younger generations grow old. Hanson argues that the relationship bet…

• Transforming Web Pages to Become Standard-Compliant through Reverse Engineering

  Benfeng Chen, Vincent Y. Shen (2006) — Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper addresses the problem of transforming legacy, non-standards-compliant web pages into valid HTML with proper separation of content and presentation — a fundamental requirement for web accessibility. In 2006, over 95% of web pages failed W3C…
