This work used heuristic evaluation to analyze whether and how deceptive patterns violate or conform to the Web Content Accessibility Guidelines and related legislation and identified three patterns implicated by the WCAG guidelines: Countdown Timer, Auto-Play, and Hidden Information.

Deceptive patterns, dark patterns, and manipulative user interfaces (UI) are a widely used design strategy that manipulates users to act against their own interests in pursuit of shareholder aims. These patterns may particularly affect people with less education, visual impairments, and older adults. Yet, access is a critical feature of the user experience (UX), development standards, and law. We considered whether and how the Web Content Accessibility Guidelines (WCAG) and related legislation, like the European Accessibility Act (EAA), could act as a tool against deceptive patterns. We used heuristic evaluation to analyze whether and how deceptive patterns violate or conform to these guidelines and legal statutes.
