• Towards Testing the Accessibility of Dynamic Visual Changes in Android Mobile GUI with Multi-Modal LLMs

  Mengxi Zhang, Jianlin Yu, Chen Xu, Jiqun Li, Xinglong Yin, Huaxiao Liu · 2026 · ACM Transactions on Computer-Human Interaction

  This paper addresses a long-standing gap in mobile accessibility testing: dynamic visual changes in Android GUIs that communicate task status or feedback to sighted users but are invisible to blind users of screen readers such as TalkBack. Examples include an input field…

• Look Ma, No ARIA: Generic Accessible Interfaces for Web Widgets

  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 automatically detects, classifies, and…

• 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 processing, including…

• Evaluating the Accessibility of Rich Internet Applications

  Nádia Fernandes, Daniel Costa, Sergio Neves, Carlos Duarte, Luís Carriço · 2012 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper addresses a critical gap in automated accessibility evaluation: most tools only assess the initial HTML served to the browser, missing the dynamically generated content that defines modern Rich Internet Applications (RIAs). Web applications using JavaScript and AJAX…
