The focus of much academic work on Web accessibility has been concerned with the lack of implementation of the Web Content Accessibility Guidelines. There seems, as yet, however, to have been little critical reflection on the Guidelines themselves — save perhaps some awareness of the heterogeneous nature of the Web, and the difficulties facing Web developers trying to ensure their work displays true to their intentions across a wide range of different browsers and devices, making use of continually evolving and contested code. Yet, as this paper highlights, the long drawn out process by which version 2.0 of the WCAG came into being hides many skeletons, including aspects of the process of developing standards that bear closer scrutiny, and reveal much when viewed through Latourian eyes. The findings of this paper suggest that the WCAG2.0 are almost irrelevant today — to the detriment of those for whom they were made — and that the process of creating them was at fault.

This chapter examines the website accessibility of museums located in Portugal (N = 575), based on the web content accessibility guidelines (WCAG 2.0), and on the three type of conformance levels (A, AA, and AAA), using two web diagnostic tools: AccessMonitor and TAW (Test de Accessibilidad Web). The results show that the average accessibility of museum websites is 5.80 on a scale from 1 to 10. However, while according to AccessMonitor, there are 14 websites (2.43% of the total) with a level of accessibility of 10 (excellent web accessibility practices); there are also some websites with a global index lower than 3 (classified as bad practice). The results obtained through TAW show that an average of 58.43 problems were identified in each website analyzed. These results highlight that several improvements should be introduced in the websites of Portuguese museums in order to make information available to all people.

Web services are an emerging technology that has attracted much attention from both the research and the industry sectors in recent years. The exploitation of Web services as components in Web applications facilitates development and supports application interoperability, regardless of the programming language and platform used. However, existing Web services development standards do not take into account the fact that the provided content and the interactive functionality should be accessible to, and easily operable by, people with disabilities. This chapter presents a platform named myWebAccess, which provides a mechanism for the semi-automated “repair” of Web services' interaction characteristics in order to support the automatic generation of interface elements that conform to the de facto standard of the Web Content Accessibility Guidelines 2.0. myWebAccess enhances interaction quality for specific target user groups, including people with visual and motor disabilities, and supports the use of Web services on diverse platforms (e.g., mobile phones equipped with a browser). The Web developers can build their own design templates and the users of myWebAccess can create a personalized environment containing their favourite services. Thus, they can interact with them through interfaces appropriate to their specific individual characteristics.

With the growth of e-services in the past two decades, the concept of web accessibility has been given attention to ensure that every individual can benefit from these services without any barriers. Web accessibility is considered one of the main factors that should be taken into consideration while developing webpages. Web Content Accessibility Guidelines 2.0 (WCAG 2.0) have been developed to guide web developers to ensure that web contents are accessible for all users, especially disabled users. Many automatic tools have been developed to check the compliance of websites with accessibility guidelines such as WCAG 2.0 and to help web developers and content creators with designing webpages without barriers for disabled people. Despite the popularity of accessibility evaluation tools in practice, there is no systematic way to compare the performance of web accessibility evaluators. This paper first presents two novel frameworks. The first one is proposed to compare the performance of web accessibility evaluation tools in detecting web accessibility issues based on WCAG 2.0. The second framework is utilized to evaluate webpages in meeting these guidelines. Six homepages of Saudi universities were chosen as case studies to substantiate the concept of the proposed frameworks. Furthermore, two popular web accessibility evaluators, Wave and SiteImprove, are selected to compare their performance. The outcomes of studies conducted using the first proposed framework showed that SiteImprove outperformed WAVE. According to the outcomes of the studies conducted, we can conclude that web administrators would benefit from the first framework in selecting an appropriate tool based on its performance to evaluate their websites based on accessibility criteria and guidelines. Moreover, the findings of the studies conducted using the second proposed framework showed that the homepage of Taibah University is more accessible than the homepages of other Saudi universities. Based on the findings of this study, the second framework can be used by web administrators and developers to measure the accessibility of their websites. This paper also discusses the most common accessibility issues reported by WAVE and SiteImprove.

The purpose of this study was to determine the conformance levels of government websites in Sub-Saharan Africa (SSA) to Web Content Accessibility Guidelines (WCAG) 2.0 and examine which macro factors influenced the accessibility these websites. The findings indicated that the majority of government websites in SSA still had a long way to go to become accessible based on the WCAG 2.0 standards. None of the 217 government websites examined adhered to all the WCAG 2.0 guidelines. Cross country analysis showed that there are three macro factors influencing e-government accessibility in SSA, namely Human Development Index (HDI), Corruption Perception Index (CPI), and percentage of the active population (15-64 years). Countries with high HDI levels and low CPI levels tend to have websites with fewer accessibility errors, while those for countries with high percentage of the active population have more accessibility errors.
