Interdependent components of web accessibility

Abstract

Increasingly, the Web is providing unprecedented access to information and interaction for people with disabilities. However, the Web will not be equally accessible, allowing people with disabilities to access and contribute to the Web, until: • Authoring tools and development environments (including content managements systems such as blogging applications) produce accessible Web content and have accessible interfaces; • Browsers, multimedia players and assistive technologies provide a completely usable and accessible experience; • Content is designed to be accessible. Web accessibility relies on tools that are designed to work together and support the needs of the people who use them. This paper describes how Web accessibility depends on several components working together. It demonstrates the relationship between the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI) guidelines: Web Content Accessibility Guidelines (WCAG), Authoring Tool Accessibility Guidelines (ATAG), and User Agent Accessibility Guidelines (UAAG).

Accessibility levels of Portuguese enterprise websites: equal opportunities for all?

“…In fact, the issue of accessibility has two main components (Chisholm and Henry, 2005), the technical components (related to the tools and the content that we are working with), and the human component, involving content producers, end-users and tool developers. This means that, "to realise the dreams of people with disabilities", tools have to enable the creation and modification of the content in web pages which must be made accessible.…”

Mejora de la accesibilidad web mediante el uso de agentes inteligentes

“…Esta facilidad de publicación, junto con el aumento de la cobertura de los medios, se ha convertido en una revolución en la forma en que la Web se está utilizando. Por lo tanto, alcanzar el atributo de calidad de la Accesibilidad Web ya no es solo un desafío de las organizaciones que desarrollan estándares y guías de accesibilidad, y de los desarrolladores de aplicaciones Web, sino que ha tomado tal dimensión que para poder garantizar la misma, es necesario que una serie de componentes existan y cooperen [7] entre sí para poder disminuir la brecha entre los mismos. A continuación se presentan dichos componentes y se analiza su vinculación con las directrices propuestas por la WAI.…”
