Abstract [en]
As WCAG 2.2 is a recently introduced accessibility standard, limited research exists on how its guidelines affect navigation and user experience for visually impaired users. This study examines how compliance with the Web Content Accessibility Guidelines (WCAG) 2.2 contrast ratio requirements influence accessibility and user experience. A mixed-methods survey was conducted with seven participants; however, only responses from visually impaired users were analysed, resulting in a final sample of six participants. Data collection included absolute category ratings (1–5) assessing readability and navigation across three high-fidelity prototypes with varying accessibility compliance levels (AAA, AA, and non-compliant), alongside open-ended questions. Quantitative data were analysed statistically, while qualitative responses underwent thematic analysis. Findings suggest that higher WCAG 2.2 contrast ratio compliance generally improves readability and navigation. However, the prototype with maximum AAA compliance was rated least user-friendly, indicating that user experience is influenced not only by contrast ratio compliance, but also by factors such as cognitive load and design conventions.
