In June 2019, Marcy Sutton conducted accessibility research with Fable Tech Labs, focusing on user testing of client-side routing techniques in JavaScript web applications to identify the most intuitive and ergonomic methods for users with disabilities. The initiative aimed to gather insights on how different navigation techniques impact the user experience, particularly in single-page applications where traditional page reloads are absent. Common accessibility barriers include issues with screen reader announcements, focus management, and the visibility of focus outlines. The research involved testing various prototypes, each employing different focus management strategies, with users utilizing assistive technologies like screen readers, screen magnification, and voice navigation. The findings emphasized the importance of responsive design, visible focus outlines, and tailored focus management techniques to enhance accessibility. Recommendations included implementing interactive UI controls, ARIA Live Regions, and skip links to improve navigation and focus management, aiming for a more inclusive web experience. The research underscored the value of user testing in making informed accessibility improvements and highlighted the need for collaboration with users with disabilities to develop effective solutions.
