Summary
This paper addresses a gap in web accessibility practice: while automated testing tools can catch structural violations, they cannot reliably assess the quality of alternative text, the usability of dynamic content, or many other issues that only human users can identify. The EU European Parliament Directive already mandates feedback mechanisms on public sector websites, yet existing feedback tools are not designed for or tested with users with disabilities. The authors used a participatory design approach to develop a universal, standalone, browser-independent accessibility feedback form that prioritizes the needs of visually impaired users. The research involved four phases: an exploratory literature review and online survey (N=40, of whom 31 had visual impairments including 19 who were blind) to understand user challenges; focus group discussions (N=12) and expert interviews with accessibility-specialized web developers (N=3) to inform design; prototyping based on four design rationales (universal access, guided feedback process, user empowerment with transparent information collection, and holistic accessibility and usability focus); and evaluation with 16 feedback submissions and in-depth interviews with five visually impaired users. The resulting form incorporates 21 design features organized into eight feature groups, covering everything from how users locate and access the form (prominent link placement, separate browser tab, ARIA labels) through structured feedback collection (checkboxes for assistive technologies used, guided problem description with tips) to submission and follow-up (no CAPTCHA, confirmation notification, contact point for questions).
Key findings
The online survey revealed nine categories of accessibility challenges faced by visually impaired users, with login/CAPTCHA issues most frequently cited (21 mentions), followed by website structure problems (17), advertising/pop-ups (15), and form completion difficulties (14). Thirty of the 40 survey participants used screen readers regardless of their level of visual impairment, often in combination with magnification, voice control, and braille displays. In the prototype evaluation, developers rated the quality of collected feedback at an average of 5.28 on a 7-point scale across six dimensions (specificity, reproducibility, actionability, conciseness, relevance, and quality). Reproducibility and relevance scored highest (means of 5.48 and 5.92), while specificity and quality scored lower (5.12 and 4.98). Users rated the form's accessibility at 8.40 out of 10. All five interviewed feedback providers appreciated the structured, guided approach, with headlines helping screen reader users navigate efficiently. Key design decisions validated by evaluation included: opening in a separate browser tab (pop-ups are problematic), minimizing mandatory fields (only problem description and privacy policy), omitting CAPTCHAs (major barrier for visually impaired users), and providing transparent explanations of why data is collected. The study also found that users were sensitive about automatic data collection — they preferred manual input for browser and OS information despite the convenience of auto-detection.
Relevance
This research is directly actionable for any organization maintaining public-facing websites, particularly those required by law to provide accessibility feedback mechanisms. The eight design recommendations offer a practical blueprint: provide a visible link to the feedback form, open it in a separate tab, use clear headline structure, ensure transparent communication about data collection, minimize mandatory fields, avoid or carefully implement CAPTCHAs, acknowledge submissions promptly, and include a contact point. The participatory approach — involving visually impaired users throughout design rather than just in testing — demonstrates how to build tools that genuinely serve their intended users. A notable limitation is the study's focus on visual impairments, potentially overlooking the needs of users with motor, cognitive, or hearing disabilities. The form prototype and its open-source implementation provide a concrete starting point for organizations looking to collect structured accessibility feedback that developers can actually act on, bridging the gap between user-reported barriers and technical remediation.
