Summary
This doctoral consortium paper presents early-stage research on automatically evaluating and repairing accessibility problems in Rich Internet Applications (RIAs). The author identifies a critical gap: as the web evolves from static pages to complex, dynamic applications, existing accessibility evaluation and repair tools fail to account for all possible states and variations of RIAs, producing incomplete results. Most automated evaluators at the time were outdated (still based on WCAG 1.0), incomplete in their coverage of more elaborated guidelines, and entirely ignored the dynamic aspects of RIAs. The research builds on QualWeb, an accessibility evaluator developed at the University of Lisbon that uses WCAG 2.0 and simulates browser processing to trigger interactive elements and access all different states of a RIA. By navigating through these states programmatically, QualWeb can identify accessibility differences between states, determine which dynamic web constructs generate the most accessibility barriers, and assess how the overall accessibility quality of a RIA is affected across its full range of states.
Key findings
The research identifies three key questions for understanding RIA accessibility: how compliance and violations occur in the dynamic web, which problems can be corrected automatically, and which require human intervention. The paper notes that existing repair tools like the Social Accessibility Project and HTML Tidy do not consider browser processing or RIA complexity, limiting their effectiveness. The proposed approach extends QualWeb with repairing capabilities that combine automatic repair with developer-suggested corrections, creating a feedback loop where repairs of common RIA accessibility problems can be refined over time. The work is aligned with W3C and European research priorities, specifically the WAI-ACT project, which was focused on supporting the practical implementation of web accessibility standards.
Relevance
This paper addresses a problem that remains highly relevant today: the gap between accessibility evaluation tools designed for static content and the reality of modern dynamic web applications. While the paper is an early-stage doctoral position paper rather than a full study with results, it clearly articulates why traditional accessibility testing approaches fall short for single-page applications and dynamically-rendered content — a challenge that has only intensified with the rise of JavaScript frameworks like React, Angular, and Vue. The concept of automated accessibility repair, moving beyond just identifying problems to proposing and applying fixes, anticipated a direction that modern tools like axe and browser DevTools are still working toward. For practitioners, the paper reinforces that accessibility testing must account for all interactive states of an application, not just the initial page load.
