Creating web pages has become a challenging task in the last years. Today web pages and web applications have to work a large variety of devices. On top of these requirements web developers have also to care about accessibility. The primary guidelines for accessible web pages are the Web Content Accessibility Guidelines published by the W3C. These guidelines define several requirements for accessible web pages. The W3C also publishes recommendations how these guidelines can be implemented. Currently a new standard is in development which specifies a format for writing rules for testing the accessibility of web pages and to harmonize the interpretation of the guidelines.
Nevertheless, evaluating the accessibility of a web page is a time consuming task. The process can also be error prone, depending on the experience of the user [1]. This talk will present the prototype of semiautomatic tool for evaluating the accessibility of web pages. The tool uses a combination of automatic and guided manual testing to make accessibility evaluations less time consuming and error prone. For implementing the tool several well known projects like Selenium are used. The first part of the talk will give a brief overview about the standards for accessible web pages and the procedures for testing the accessibility of web pages. One of the main challenges in the development of the tool was the modeling of the rules for accessible web pages in a machine readable way. In the main part of the talk the model used for the rules as well as the implementation of the test procedures will be discussed. The last part of the talk will be a live demonstration of the of the tool presented in this talk.
