Integrating Manual and Automatic Evaluations to Measure Accessibility Barriers

Explicit syntax and implicit semantics of Web coding are typically addressed as distinct dominions in providing metrics for content accessibility. A more down-to-earth portrait about barriers and their impact on users with disabilities could be obtained whether any quantitative synthesis about number and size of barriers integrated measurements from automatic checks and human assessments. In this work, we present a metric to evaluate accessibility as a unique meas-ure of both syntax correctness and semantic consistence, according to some general assumptions about relationship and dependencies between them. WCAG 2.0 guidelines are used to define boundaries for any single barrier eval-uation, either from a syntactic point of view, or a subjective/human one. In or-der to assess our metric, gathered data form a large scale accessibility monitor has been utilize

Web accessibility compliance for e-Government websites in the Gulf region

The World Wide Web is a digital platform that helps people access and retrieve information in an accessible and equitable manner. However, people with disabilities can face a number of challenges when it comes to using the Web and accessing content on websites. According to Henry, web accessibility means “that people with disabilities can use the Web. More specifically, Web accessibility means that people with disabilities can perceive, understand, navigate, and interact with the Web, and that they can contribute to the Web” (2005, para.1). While different countries across the globe tackle issues of equitable access to the web via policy and legal instruments, not all countries and regions have shown progress in terms of meeting the requirements of the internationally recognised Web Content Accessibility Guidelines (WCAG 2.0). This research aimed to evaluate web accessibility and practice in e-government websites in three Arabian Gulf countries. The study sought to identify accessibility issues and discover levels of conformance to the WCAG 2.0 web accessibility standards, while also eliciting awareness and knowledge of web accessibility in practice. Exploratory research methods were applied in this study, including case studies of nations. Automated website assessments, manual assessments and document analysis were amongst the instruments used within this research. In terms of web evaluation, the findings from the evaluation conducted on e-government websites in relation to ten different sites from each of the three selected countries indicated that there was no clear evidence of an even minimal levels of accessibility features for people with disabilities. Furthermore, the webpages that were tested showed accessibility problems across nearly all aspects of the WCAG 2.0 guidelines. In terms of accessibility awareness for the organisations e-government websites examined in this study, document analysis showed that none of the government websites of Kuwait, the UAE and Qatar made specific reference to web accessibility standards, or where they did, they were not implemented. The results showed that laws and policies did exist for people with disabilities, but did not seem applicable in terms of government run e-services or content. In fact, this interpretation revealed a lack of awareness within the websites examined, despite the existence of laws and policies designed to protect and support people with disabilities. The aim of this study was to understand the role that web accessibility plays in gulf nation egovernment services, and whether citizens of these nations are being supported in relation to access to online digital resources and services. Whilst other nations have seemed to recognise the need to make government services available to all citizens, including those with disabilities, this research finds that whilst Kuwait, the UAE and Qatar enshrine the rights of people with disabilities into law, these rights do not yet seem to have found their way to the digital domain

Accessibility of Thai university websites: Awareness, barriers and drivers for accessible practice

Governments and organizations have to respond to a range of legislative and policy initiatives intended to promote equal opportunity for all. The Thai government has passed a number of laws which aim to protect its citizens from discrimination and from breaches of their human rights by government departments and agencies. The Persons with Disabilities Education Act B.E. 2551 (2008) and the Thailand Information and Communication Technology (ICT) Policy Framework (2011-2020) required government agencies to delivery equal education and access to online information for all Thais. Most Thai universities receive government subsidies, and therefore have an obligation to contribute to national prosperity so that all Thais can benefit from their activities, or as the Ministry of Information and Communication Technology and The National Electronics and Computer Technology Centre (2011, p. 23) states “The creation of content, database, online content which promotes lifelong learning, the development of school websites and other digital content should follow the web accessibility standard”. Given the Thai government’s commitment to lifelong learning and the creation of accessible materials, this thesis sought to investigate to what level Thai universities were implementing web accessibility in their websites and e-learning materials. A mixed method approach was employed in order to explore the level of accessibility awareness, barriers to web accessibility implementation and possible drivers for accessibility uptake which might exist within Thai universities. Quantitative data derived from automated and manual web evaluations was gathered based on WCAG 2.0 guideline in order to determine the actual levels of accessible design apparent in Thai university websites. Fifty representative universities were selected from the top ranked Thai universities and a number webpages were tested from within each of the university websites. In addition, online surveys were conducted with three stakeholder groups within the Thai university sector, namely lecturers, web staff and senior managers. These surveys were design to set the context for quantitative website assessment findings and provide evidence as to these stakeholders understanding of web accessibility as a concept. Finally, follow-up interviews were conducted after the web assessments and surveys were analysed so as to reduce ambiguity and increase understanding, creating a very clear picture of the standing of web accessibility in Thailand’s universities. The findings of the data analysis indicate that Thai universities have low levels of web accessibility implementation in their websites and e-learning materials, even though web accessibility requirements had been embedded in Thai laws and policies for over a decade. In terms of web evaluation, the university webpages had accessibility problems across all aspects of WCAG 2.0’s POUR principles, with not a single tested webpage passing even the lowest level of WCAG 2.0 compliance. The survey and interview data revealed very low levels of awareness of web accessibility amongst Thai university staff members as well as lack of knowledge regarding students with disabilities and their specialised technology needs. Whilst Thai university staff were generally supportive of the concept of web accessibility and supporting students with special needs, this was accompanied by some less supportive views, including students with disabilities being taught only in specialised educational facilities or only where there were sufficient numbers of such students to make the investment in accessibility worthwhile. A number of universities in this study featured university admission requirements which could be classed as a discriminatory and not aligned with the requirements of the Thai government. In fact, this thesis revealed an almost total lack of awareness within the Thai university sector of Thai government policy regarding web accessibility and equality in education. This thesis proposed a Smart Thailand : Accessible Learning model and an associated implementation framework which together might lead to an environment in which Thai universities would be more willing and able to implement the tenets of web accessibility and provide an equitable learning experience for all Thai citizens, especially those with disabilities

Accesibilidad en entornos web interactivos: superación de las barreras digitales

A diario, millones de personas sin conocimientos técnicos publican contenido en la web en blogs, wikis, redes sociales, etc. A pesar de existir recomendaciones de accesibilidad, como las pautas WCAG y ATAG de la W3C y que estas se han convertido en normativas (la norma ISO/IEC 40500:2012, la norma UNE 139803:2012 en España, o la Sección 508 en Estados Unidos) e incluso leyes de obligado cumplimiento, la accesibilidad de la web es todavía una característica raramente implementada hoy en día. Los usuarios, inconscientemente, siguen publicando contenido que presenta barreras a las personas con discapacidad y que afectan sus derechos civiles. Esta tesis doctoral explora esta problemática y, con la intención de solucionarla, pone el foco en la comunicación de las barreras de accesibilidad a las personas que publican contenido en la web sin conocimientos técnicos. La hipótesis que fundamenta la tesis es que «reduciendo la complejidad de la información relacionada con la accesibilidad, se propiciaría la aplicación de criterios de autoría accesibles, aumentando la calidad general del contenido web». A partir de técnicas relacionadas con el DCU y la Ingeniería Semiótica (IngSem) se hace una propuesta de comunicación de las barreras de accesibilidad, que se demuestra en una prueba de concepto, el sistema Emphatic Editor for Accessibility (EE4A).Diàriament, milions de persones sense coneixements tècnics publiquen contingut a la web a blogs, wikis, xarxes socials, etc. Tot i que existeixen recomanacions d’accessibilitat, com les pautes WCAG i ATAG de la W3A i que aquestes s’han convertit en normativa (la norma ISO/IEC 40500:2012, la norma UNE 139803:2012 a Espanya, o la Secció 508 als Estats Units) i a més hi ha lleis d’obligat compliment, l’accessibilitat de la web és encara una característica rarament implementada avui en dia. Els usuaris, inconscientment, segueixen publicant continguts que presenten barreres per a les persones amb discapacitat i que afecta als seus drets civils. Aquesta tesi doctoral explora aquest problemàtica i, amb la intenció de solucionar-la, posa el focus en la comunicació de les barreres d’accessibilitat a les persones que publiquen contingut a la web sense coneixement tècnics. La hipòtesis que fonamenta la tesi és que « reduint la complexitat de la informació relacionada amb l’accessibilitat, es propiciaria l’aplicació de criteris d’autoria accessibles, augmentant la qualitat general del contingut web». A partir de tècniques relacionades amb el DCU i l’Enginyeria Semiòtica (IngSem) es fa una proposta de comunicació de les barreres d’accessibilitat, que es demostra en una prova de concepte, el sistema Emphatic Editor for Accessibility (EE4A).Every day, thousands of users with non-technical knowledge publish web content on blogs, wikis, social networks, etc. Although there are accessibility recommendations, such as WCAG and ATAG W3C guidelines, and that they have become standards (ISO/IEC 40500: 2012, UNE 139803: 2012 in Spain, or Section 508 in United States) and even mandatory laws, web accessibility is still a feature rarely implemented today. Users, unconscious of accessibility requirements, keep on publishing content which presents barriers to people with disabilities, and which impact their civil rights. This PhD explores this issue, aiming at find a solution, and puts the focus on the communication of accessibility barriers to people who publish web content without technical knowledge. The hypothesis underlying the thesis is that «reducing the complexity of the information related with accessibility would help the application of accessible criteria in authoring, and would increase the overall quality of web content». With techniques related with DCU and Semiotics Engineering (IngSem), the PhD thesis makes a proposal of communication of accessibility barriers, demonstrated through a proof of concept, the Emphatic Editor for Accessibility (EE4A)
