A Comparative Test of Web Accessibility Evaluation Methods

After a quick review and description of methods, the paper illustrates a comparative test of two web accessibility evaluation methods: conformance testing and barrier walk through | Giorgio Brajnik, Dipartimento di Matematica e Informatica, Università di Udine | October 2008

Accessibility auditors have to choose a method when evaluating accessibility: expert review (a.k.a. conformance testing),user testing, subjective evaluations, barrier walkthrough are some possibilities. The comparison in this study aims at determining merits of barrier walkthrough, using conformance testing as a control condition. A comparison framework is outlined, followed by the description of a laboratory experiment with 12 subjects (novice accessibility evaluators), and its results.
