It's important for Web designers to have a basic understanding of the mechanics of human visual perception. To the extent that your pages are 'easy on the eyes,' readers will find your site more inviting and more readable. Conversely, pages that visually overstimulate a reader are not only more difficult to read, but much more likely to result in eyestrain, fatigue, even headaches (none of which is particularly popular among readers).

Whenever I ask a large group of people whether or not they have a visual disability, very few of them answer that they do. Then I ask whether or not anyone uses any assistive technology to overcome their visual disability. Most people are unsure what I mean. Invariably, though, as I look out across the group, I see many of them--often a majority--using an assistive technology for their vision at that very moment.

Visual vs. Cognitive Disabilities
Graphics are not directly accessible to people who are blind, yet graphics can be beneficial (in some cases necessary) to individuals with cognitive disabilities. Are these two disability types at odds with each other? How can Web developers reconcile the needs of these two very different audiences? Read more about the apparent conflicting interests in our feature article.

Visually Challenged Users and Need for a Universally Accessible Web Site
Visually impaired people suffer from no faults of their own. This is quite worthy of consideration that a little more efforts toward adoption of certain features in your web site can help them retrieve information in the desired manner. Their ease of accessibility to your web site will not go unrewarded; they can well augment your business interests by turning into your most valuable customers.

Voice Interfaces: Assessing the Potential
Visual interfaces are inherently superior to auditory interfaces for many tasks. The Star Trek fantasy of speaking to your computer is not the most fruitful path to usable systems.

Niniejsza książka odpowiada na dwa pytania. Pierwsze brzmi: 'Dlaczego powinienem uczynić swoją stronę WWW bardziej dostępną?' Jeżeli nie masz strony w sieci, ta książka nie jest dla Ciebie. Drugie pytanie to 'Jak mogę uczynić moją stronę bardziej dostępną?' Jeżeli nie zostaniesz przekonany przez odpowiedź na pierwsze pytanie, nie będziesz zainteresowany odpowiedzią na drugie.

WAVE is a free web accessibility evaluation tool provided by WebAIM. It is used to aid humans in the web accessibility evaluation process. Rather than providing a complex technical report, WAVE shows the original web page with embedded icons and indicators that reveal the accessibility of that page.
In order to encourage vendors of non-W3C technologies to include accessibility features in their technologies, and in recognition of emerging technologies that are beneficial for the Web, WCAG 2.0 is technology neutral. Rather than list each technology that the guidelines cover, WCAG 2.0 introduces the concept of a baseline. This post attempts to explain what is meant by this baseline concept.

There are many legal issues currently raised by the growth in e-commerce and e-learning, but one of the least discussed is that of Web accessibility. As a result of the increased use of proprietary technologies and a failure to follow guidelines when designing Web sites a large percentage of the Internet remains inaccessible to many parts of the disabled community. As a result, the effect has been to exclude a significant section of the population from fully benefiting and participating in the increased use and reliance on e-commerce and e-learning. The purpose of this paper is to explore, in light of events and experiences elsewhere in the world, whether and to what extent the disability rights legislation in the UK might apply in such a scenario. It also considers the effect of the recent Special Educational Needs and Disability Act 2001 on the previously excluded area of education.

Web Accessibility Evaluation Tools: Overview
Web accessibility evaluation tools are software programs or online services that help determine if a Web site meets accessibility guidelines. While Web accessibility evaluation tools can significantly reduce the time and effort to evaluate Web sites, no tool can automatically determine the accessibility of Web sites.

Web Accessibility for People With Disabilities: An Introduction for Web Developers

This article presents an overview of the topic of web access for people with disabilities. First, we describe the four basic disabilities and explain the benefits of making sites accessible, as well as the reasons that more sites are not accessible. We review the relevant laws regarding web access, and we then discuss efforts being made by vendors and professional organizations, especially Microsoft and the World Wide Web Consortium, to encourage accessibility. Finally, we describe major resources that web developers might consult to assist them in making their sites accessible to people with disabilities.

Web Accessibility for Section 508
The legislation referred to as "Section 508" is actually an amendment to the Workforce Rehabilitation Act of 1973. The amendment was signed into law by President Clinton on August 7, 1998. Section 508 requires that electronic and information technology that is developed by or purchased by the Federal Agencies be accessible by people with disabilities.

Web Accessibility Initiative (WAI)
It might be easy to dismiss the WAI as another mouthful of acronyms for yet another Web standard but that would be a mistake. Their goal is to, '…make Web content more available to all users, whatever user agent they are using (e.g., desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.) or constraints they may be operating under (e.g., noisy surroundings, under- or over-illuminated rooms, in a hands-free environment, etc.).' To meet this goal, the WAI identifies two primary principles for accessible design, which are totally in keeping with the basic principles of usability: 'Ensure graceful transformation' and 'Make content understandable and navigable.' There are fourteen guidelines that help authors understand and implement these principles. Each includes a description and rationale, along with links to other resources and a set of checkpoints. A related document shows detailed techniques for implementing accessible web pages. Even if you are not primarily concerned wi
