• Wizard-of-Oz evaluation of speech-driven web browsing interface for people with vision impairments

  Vikas Ashok, Yevgen Borodin, Svetlana Stoyanchev, Yuri Puzis, I. V. Ramakrishnan (2014) — Proceedings of the 11th Web for All Conference (W4A)

  This paper presents a Wizard-of-Oz study with 24 blind participants to evaluate the usability and effectiveness of speech-driven web browsing as an alternative to traditional keyboard-based screen reader interaction. The study was motivated by three …

• Using simultaneous audio sources to speed-up blind people's web scanning

  João Guerreiro (2013) — Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This doctoral consortium paper proposes using multiple simultaneous audio sources to help blind users scan web content faster. The core problem is that screen readers present information sequentially — one item at a time — while sighted users can vis…

• Pushing the Raman principle

  Clayton Lewis (2013) — Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper explores the implications of what the author calls the "Raman Principle," attributed to T.V. Raman: "The way to think about the visual system is as a way to answer queries against a spatial database. If you have an alternate way to ask the…

• Are Users the Gold Standard for Accessibility Evaluation?

  Amaia Aizpurua, Myriam Arrue, Simon Harper, Markel Vigo (2014) — Proceedings of the 11th Web for All Conference (W4A)

  This paper critically examines whether user testing with blind users is a reliable "gold standard" for web accessibility evaluation. Drawing on an exploratory study with 11 legally blind participants (10 JAWS users, 1 VoiceOver user, ages 21-64) who …

  Valentyn Melnyk, Vikas Ashok, Yury Puzis, Yevgen Borodin, Andrii Soviak, I. V. Ramakrishnan (2015) — Proceedings of the 12th International Web for All Conference (W4A)

  This paper proposes an alternative approach to web widget accessibility that bypasses ARIA entirely. Rather than relying on web developers to correctly implement ARIA markup — which is often missing, incorrect, or inconsistent — the system automatica…

  Yury Puzis, Yevgen Borodin, Andrii Soviak, Valentyn Melnyk, I. V. Ramakrishnan (2015) — Proceedings of the 12th International Web for All Conference (W4A)

  This paper argues that the primary barrier to web accessibility is not technical limitations but the high cost of implementing WAI-ARIA, the W3C accessibility specification for rich internet applications. The authors systematically analyze why ARIA i…
