Tools for Web Accessibility Evaluation

A Declarative Model for Web Accessibility Requirements and its Implementation

“…The different approaches for evaluating the accessibility of a web page may be categorized into three categories (Abascal et al, 2019;Nuñez et al, 2019):…”

Testing by experts is the most effective way, and user testing works most effectively to verify how people with disabilities perform specific tasks on a web page (Abascal et al, 2019;Nuñez et al, 2019).

The currently available automated tools may produce different results, false negatives, or false positives because of different implementations of the guidelines.…”

Requirements for Large Scale Web Accessibility Evaluation

Thus, we carried out a first analysis of the currently available solutions in terms of tools, which can support stakeholders in assessing accessibility compliance, detecting barriers, supporting Web developers in knowing how to solve them and commissioners and public bodies in monitoring the accessibility over time.…”
