Barrier Walkthrough Method

An accessibility evaluation method developed by Giorgio Brajnik that groups Web Content Accessibility Guidelines (WCAG) success criteria by user categories such as blind users, people with low vision, and motor-impaired users. Unlike standard WCAG audits that evaluate all criteria sequentially, the Barrier Walkthrough allows evaluators to focus on the specific barriers experienced by particular disability groups, making it easier to identify and prioritize issues that affect real users. The method classifies detected barriers by severity (minor, significant, critical), providing a more nuanced picture of accessibility impact.
