An Architecture For Multiple Web Accessibility Evaluation Environments

Modern Web sites leverage several techniques that allow for the injection of new content into their Web pages (e. g., AJAX), as well as manipulation of the HTML DOM tree. This has the consequence that the Web pages that are presented to users (i.e., browser environment) are different from the original structure and content that is transmitted through HTTP communication (i.e., command line environment). This poses a series of challenges for Web accessibility evaluation, especially on automated evaluation software. In this paper, we present an evaluation framework for performing Web accessibility evaluations in different environments, with the goal of understanding how similar or distinct these environments can be, in terms of their web accessibility quality.
