A test procedure for checking the WCAG 2.0 guidelines

Abstract

The Internet is an indispensable part of our everyday life today. Worldwide the number of Internet users from 1997-2014 has increased from 121 million to 2.9 billion - that represents an increase from 2 percent to 40 percent of the world’s population [1]. Despite this growth there are barriers to Internet use. This is especially true for people with disabilities. To minimize this, the Web Content Accessibility Guidelines (WCAG) 2.0 specifies guidelines on how a web page can be created to optimize accessibility. In this paper a web-based test procedure as prototype is going to be presented. The accompanying prototype supports the test of all success criteria. The paper is based on an empirical study and evaluation of existing automatic test tools, which are used for the test procedure. As a result, the tester obtains a numerical value about the degree of accessibility. That’s a statement of how well the web page meets the success criteria.
