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 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.

Objective: The present study examined whether implementing recommendations of Web accessibility guidelines would have different effects on nondisabled users than on users with visual impairments. Background: The predominant approach for making Web sites accessible for users with disabilities is to apply accessibility guidelines. However, it has been hardly examined whether this approach has side effects for nondisabled users. A comparison of the effects on both user groups would contribute to a better understanding of possible advantages and drawbacks of applying accessibility guidelines. Method: Participants from two matched samples, comprising 55 participants with visual impairments and 55 without impairments, took part in a synchronous remote testing of a Web site. Each participant was randomly assigned to one of three Web sites, which differed in the level of accessibility (very low, low, and high) according to recommendations of the well-established Web Content Accessibility Guidelines 2.0 (WCAG 2.0). Performance (i.e., task completion rate and task completion time) and a range of subjective variables (i.e., perceived usability, positive affect, negative affect, perceived aesthetics, perceived workload, and user experience) were measured. Results: Higher conformance to Web accessibility guidelines resulted in increased performance and more positive user ratings (e.g., perceived usability or aesthetics) for both user groups. There was no interaction between user group and accessibility level. Conclusion: Higher conformance to WCAG 2.0 may result in benefits for nondisabled users and users with visual impairments alike. Application: Practitioners may use the present findings as a basis for deciding on whether and how to implement accessibility best.

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 content should suit both a general audience and visually-impaired individuals. Therefore, Web applications should be assessed against accessibility standards as Web Content Accessibility Guidelines (WCAG) and the Brazilian e-Government Accessibility Model (eMAG). This chapter presents MIAV's development process and the obtained results. The MIAV complies with the WCAG and eMAG, combining automated and user-opinion-based assessment approaches. First, a pilot test was run to fine-tune MIAV. Next, participants were asked to identify and report several accessibility issues on IFFluminense's Portal, Q-Academico, and Moodle. They then suggested enhancements for better browsing experience. AccessMonitor was run and tested the same Web pages to generate two indicators: the average accessibility index and the percentage of nonconformities by accessibility level. Results showed that none of the evaluated applications met all the accessibility criteria. These experiments allowed IFFluminense's IT degree students to raise an awareness of the significance of Web accessibility.

Abstract In recent years, translation and localization studies have started to include accessibility, and web accessibility in particular, as one of the key aspects to take into consideration when adapting a web product to another language and culture (web localization). This paper provides a comprehensive insight of the connections between these two fields and concepts and, above all, it discusses the possibility of transferring accessibility throughout the localization process. In particular, we analyze how the use of current localization and internationalization data exchange standards is connected to this notion of transfer, and how those standards may be capable of transferring accessibility qualities or information, or supporting localizers in their task. Finally, we present an analytical and pragmatic approach to explore this transferability challenge, which includes the study of the techniques proposed by the W3C to help web developers fulfil a set of success criteria that are included in the latest Web Content Accessibility Guidelines (WCAG) 2.1, in relation to their possible integration in localization and internationalization standards.

PurposeThe purpose of this paper is to investigate and identify the status of Web Content Accessibility Guidelines (WCAG) conformance levels (A, AA, AAA) and accessibility status in terms of Severity (Error, Warning and Review) and Responsibility (Editor, Webmaster and Developer) of Indian Institutes of Technology (IIT) Library websites based on Siteimprove Software-as-a-Service (SaaS) platform.Design/methodology/approachThe library websites of IITs were tested using Siteimprove web-tool to gather details pertaining to W3C's WCAG 2.1 standards. The data thus obtained were then visualized using spreadsheet software for greater insight. A partial correlation test was also done to assess the relationship between the three conformance levels.FindingsThe study could identify significant accessibility-related limitations of the IIT library websites concerning the three WCAG 2.1 conformance levels A (max IIT Bombay), AA (max IIT Dhanbad (ISM)) and AAA (max IIT Gandhinagar and IIT Varanasi (BHU)), Severity and Responsibility. A positive linear relationship exists amongst these conformance levels. The mean value of conformance levels were found to be 18.3 (A), 2.2 (AA) and 3.1 (AAA); Severity scores were found to be 14.4 (Error), 3.9 (Warning) and 5.2 (Review); and Responsibility scores were found to be 6 (Editor), 9.3 (Webmaster) and 8.3 (Developer), respectively.Practical implicationsThe study highlights the comparative picture of accessibility issues and conformance levels of the IITs' library website homepage with the help of results derived/based on Siteimprove Accessibility Checker. The findings of the study reveal that though the library website of IITs' in India possess a well-designed and easily navigable website homepage as far as their accessibility for VIPs is concerned, there are several issues that are still to be resolved.Social implicationsWorld Intellectual Property Organization's (WIPO) Marrakesh VIP Treaty (MVT) and the W3C's WCAG cater to the requirements and rights of the persons with vision-related disability of accessing information and knowledge building a steeper and deeper knowledge divide. Identifying and rectifying the shortcomings in the library websites will bridge the accessibility-divide and make the society more inclusive.Originality/valueNo previous study could be identified evaluating the accessibility issues of the library website of Indian IITs focussed on vision-disabled persons using Siteimprove. The methodology and approach of this paper have value in terms of reusability and reproducibility facilitating future studies.

AbstractNew methods of identifying and fixing accessibility issues on websites are presented in this article. The websites taken into consideration by the research are created with content management systems (like WordPress or Joomla!). Our main goal was to develop different methods to improve accessibility that may be used by various user groups (website creators, operators, content editors). Some of our methods are easy to use, some need more proficiency. The three methods we have developed (CSS/SCSS class override, MVC-based extension override, HTML output override) are described in detail. The use of an already existing method (Data entry checking) is also introduced, as well as some development options of this method. Each method is introduced in general, furthermore an example of their usage is also presented. Using the proposed methods, websites can fulfil the recommendations of the Web Content Accessibility Guidelines (WCAG) in order to make the content of the websites more accessible.
