Determination and evaluation of web accessibility

The Web is the most pervasive collaborative technology in widespread use today; however, access to the web and its many applications cannot be taken for granted. Web accessibility encompasses a variety of concerns ranging from societal, political, and economic to individual, physical, and intellectual through to the purely technical. Thus, there are many perspectives from which web accessibility can be understood and evaluated. In order to discuss these concerns and to gain a better understanding of web accessibility, an accessibility framework is proposed using as its base a layered evaluation framework from Computer Supported Co-operative Work research and the ISO standard, ISO/IEC 9126 on software quality. The former is employed in recognition of the collaborative nature of the web and its importance in facilitating communication. The latter is employed to refine and extend the technical issues and to highlight the need for considering accessibility from the viewpoint of the web developer and maintainer as well as the web user. A technically inaccessible web is unlikely to be evolved over time. A final goal of the accessibility framework is to provide web developers and maintainers with a practical basis for considering web accessibility through the development of a set of accessibility factors associated with each identified layer

Foregrounding accessibility for user experience design

textI am interested in creating generative tools and techniques for designing accessible user experiences for end users. As a user experience designer, I am working on embracing the web accessibility standards and guidelines and including them from the beginning of the User Experience (UX) design process. My projects are directed at facilitating design students and professionals to understand two things: that the broad concept of web accessibility is important, and how they can embed web accessibility into the UX design process at a very early stage. To do this, I used different media (website, posters and videos etc.) to create awareness and educate designers in an interesting, simple and engaging way. In this report, I will discuss the definition and role of accessible design, identify limitations in existing tools and methods, and demonstrate how future designers might research, prototype, analyze, and implement their designs for all users.Desig

Investigating the appropriateness and relevance of mobile web accessibility guidelines

The Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C) develop and maintain guidelines for making the web more accessible to people with disabilities. WCAG 2.0 and the MWBP 1.0 are internationally regarded as the industry standard guidelines for web accessibility. Mobile testing sessions conducted by AbilityNet document issues raised by users in a report format, relating issues to guidelines wherever possible. This paper presents the results of a preliminary investigation that examines how effectively and easily these issues can be related by experts to the guidelines provided by WCAG 2.0 and MWBP 1.0.

On the testability of WCAG 2.0 for beginners

Web accessibility for people with disabilities is a highly visible area of research in the field of ICT accessibility, including many policy activities across many countries. The commonly accepted guidelines for web accessibility (WCAG 1.0) were published in 1999 and have been extensively used by designers, evaluators and legislators. W3C-WAI published a new version of these guidelines (WCAG 2.0) in December 2008. One of the main goals of WCAG 2.0 was testability, that is, WCAG 2.0 should be either machine testable or reliably human testable. In this paper we present an educational experiment performed during an intensive web accessibility course. The goal of the experiment was to assess the testability of the 25 level-A success criteria of WCAG 2.0 by beginners. To do this, the students had to manually evaluate the accessibility of the same web page. The result was that only eight success criteria could be considered to be reliably human testable when evaluators were beginners. We also compare our experiment with a similar study published recently. Our work is not a conclusive experiment, but it does suggest some parts of WCAG 2.0 to which special attention should be paid when training accessibility evaluator

A Story About Digitalization and Those Left Out : A quantitative study exploring the effect of digitalization on web accessibility.

This thesis examines the influence of digitalization on web accessibility for people with disabilities (PwD). The central research question addressed is: "How does digitalization affect web accessibility for people with disabilities?" The hypothesis proposed in this study is that web accessibility decreases as digitalization advances, irrespective of legislation and awareness regarding the accessibility gap. The hypothesis is grounded in the observation that visual aspects are prioritized during web development, potentially overlooking the importance of web accessibility. This is an important topic of research since nearly 20% of the world's population (World Health Organization 2023), have a disability and almost everyone will experience disability at some point in their life (World Health Organization n.d.). Utilizing quantitative methods to conduct an empirical test this research evaluated the web accessibility of 49 Canadian Universities over a 15-year time period, from 2008 to 2022. Data collection utilized online sources such as the Wayback Machine. The research findings reveal that during periods of web advancements, there is an initial increase in web accessibility issues, validating the negative impact of digitalization on web accessibility. However, over time, there is a noticeable reduction in these issues, indicating an overall improvement in web accessibility. One significant factor negatively impacting web accessibility identified in this study is, the visual advancements brought about by digitalization. The effectiveness of legislation in enhancing web accessibility was investigated, focusing on compliance deadlines. The study demonstrates that compliance deadlines do not lead to increased accessibility on the web, meaning legislation fails to effectively improve web accessibility. Overall, this research highlights the immediate inaccessibility of the web resulting from digitalization. These findings emphasize the ongoing need to prioritize web accessibility amidst digital advancements. From these findings, stakeholders can work towards a more inclusive and accessible web environment for PwD.nhhma

Regulatory Compliance and Web Accessibility of UK Parliament Sites

This research seeks to review whether web accessibility and disability laws lead to strong compliance among UK e-government web sites. This study samples 130 sites of the UK members of Parliament using an online accessibility testing tool and determines if the site design complies with disability laws and Web Content Accessibility Guidelines (WCAG). Awareness is raised about issues disabled users face when attempting to use UK e-government sites. A discussion of UK and international disability law is reviewed in light of web accessibilty: the UK’s Disability Discrimination Act (DDA) of 1995 and the UN Treaty on the Rights of the Disabled. Although these mandates aim to provide equality in access to web sites for people with disabilities, the results of this study show that total openness of these sites is not widespread and the mere existance of laws does not guarantee compliance
