“…As a result, there is too much inappropriate alternative text and redundant text in Web pages. Such inappropriate texts often mislead or confuse blind users [3,8,10]. To reduce the use of these kinds of inappropriate alternative texts, we introduce a new metric for "listenability".…”

“…In addition, some of the accessibility evaluation tools check only for the existence of the ALT attribute, and this behavior sometimes misleads Web authors into inserting meaningless or redundant ALT attributes. As a result, there is too much inappropriate alternative text and redundant text, and that confuses blind users [3,8,10].…”

Accessibility-related regulations and guidelines are contributing to the steady improvement of Web accessibility. There are various accessibility evaluation tools, and they also help Web authors make their pages compliant with guidelines. As a result, an increasing number of Web pages are compliant with the evaluation tools. These days, however, blind people face the serious problem that reading Web pages is quite difficult. Improvements in information density by using visual effects such as two-dimensional layouts are making it difficult for blind people to understand the page structure. Also, inappropriate alternative texts mislead or confuse blind users.In this paper, to evaluate these kinds of usability problems, we introduce two metrics: navigability and listenability. Navigability evaluates how well structured the Web content is by using headings, intra-page links, labels, etc. Listenability denotes how appropriate the alternative texts are. By using these metrics, we summarize the historical transition of Web usability for blind people.

“…Guidelines for accessible Web sites have been developed with the participation of representatives from many organizations around the world [4], and the most important of them, the WCAG 1.0 (Web Content Accessibility Guidelines) [10] has been published as a W3C recommendation. The guidelines include several topics to be used during the development of Web pages, such as providing alternative text for audio and visual content, providing semantic markup, etc.…”

Much effort has been dedicated to develop software aids for authoring and evaluating Web pages using accessibility guidelines and standards. The evaluation of dynamic Web pages is a problem still unsolved in the field of automatic evaluation tools, since the current evaluators are only able to evaluate static Web pages. Stone and Dhiensa have addressed this problem, and proposed a method for evaluating the accessibility of dynamic Web pages using a generalized page which contains all possible outputs that can be generated by a script. In this paper, we present another approach for evaluating the accessibility of dynamic Web pages generated using XML and XSLT. The approach consists of analysing an XSLT using a structure descriptor such as DTD or XSD to determine the different types of XML documents that can be generated. The strength of the presented approach is given by the fact that the use of XML features enhances the results gathered from automatic accesibility evaluation of dynamic Web pages.
