The design of RIA accessibility evaluation tool

Most of the accessibility evaluation tools available check the accessibility of static traditional web pages (e.g., web pages encoded with only HTML) according to the accessibility guidelines (e.g., WCAG). There is an increased need to check the accessibility of Rich Internet Applications (RIAs) using automatic tools. In this paper, we present a conceptual framework for automatic evaluation of accessibility of rich Internet contents. The framework includes: web robot, RIA events controller, WAI-ARIA accessibility specifications, evaluator, and results handler. An example to demonstrate how the framework can be applied has been presented in detail.

► There is an increased need to check the accessibility of Rich Internet Applications (RIAs) using automatic tools.
► Developing a framework of a tool that can be used for automatic evaluation of accessibility of rich internet contents.
► The tool can check the accessibility of the content appearing in a web page.
► The WAI-ARIA semantics is tested using SPARQL query and then matched against the WAI-ARIA accessibility specifications.
