Presents an Accessibility Framework merging WCAG with Switzerland’s HERMES project methodology, addressing barriers in digital public services for visually impaired citizens, including enforcement, skill gaps, and fragmented policies.

Defines accessibility and inclusivity as core usability mindsets rather than checklists. Covers how inclusive design enhances usability, welcoming users across abilities, backgrounds, and contexts. Useful for public‑sector designers aligning digital inclusion goals with usability.

Creates a taxonomy of 55 types of web accessibility issues across perceivability, operability, understandability, robustness. Evaluates detection and auto‑repair tools: detection tools cover just 56% of issue types; repair tools only 23%. Highlights gaps and tool limitations.

Analyzes 1,000,000 of the most influential homepages globally. Reports an average of 51 distinct accessibility errors per page, a 10 % decrease from 2024, yet underscores ongoing usability impacts from unresolved WCAG-level defects.
