Accommodating Color Blindness

An estimated nine to twelve percent of the male population suffers from some form of color vision deficiency, commonly called 'color blindness.' It is important for computer interface designers to take into account and eliminate, if possible, any potential confusions that can arise because of color vision deficiencies. There are two major types of color blindness. The most prevalent causes are confusion between red and green. This type affects approximately eight to ten percent of the male population. In another type, an additional one to two Percent of men suffer from a deficiency in perceiving blue/yellow differences. Less than one percent of women suffer from any form of color blindness. To understand color blindness better, it is helpful to be familiar with the ways in which colors differ from each other. One standard way to discuss color is to divide it into hue, saturation and brightness (HSB).

Accountability of Accessibility and Usability

Focus on your users, all of them. Learn from mistakes currently made on the Web. If a user can't fill out a form, they can't buy anything from your site. People turned away by unusable sites will probably try a competitor's site. Don't be the site that turned people away. Make your Web site as usable and accessible as possible. It's the business savvy thing to do. It's the right thing to do. If you don't, someone just might force you legally to do it or threaten to sue.

ADA-508 Compliance and Usability Testing Techniques for Accessible Web Pages  

This scenario–based progression session will introduce basic usability testing concepts for developing accessible web pages, raise awareness of the need to comply with the Americans with Disabilities Act (ADA) Section 508, and provide resources for further investigation. Emphasis will be given to interactive discussion that centers on requirements analysis for accessible design.

Adaptive Technologies for the Visually Impaired: The Role of Technical Communicators    

This column examines emerging technologies of interest to technical communicators to help them identify those that are worthy of further investigation. It is intended neither as an endorsement of any technology or product, nor as a recommendation to purchase.

Adaptive Technologies for the Visually Impaired: The Role of Technical Communicators

Try your ordinary web browsing and e-mail with an translucent piece of plastic draped over your monitor, with your monitor partially obstructed, or with your monitor turned off. With each of these changes, you’ll have a significantly different experience. For example, if you have plastic draped over your monitor, you’ll likely have a hard time reading words, interpreting graphics, or distinguishing colors. If your monitor is partially obstructed, you’ll likely have a difficult time navigating pages, reading columnar formats, or associating graphics with text. And, of course, if your monitor is off, you’ll have an entirely different set of challenges in accessing and using information. Each scenario offers a different view of the information onscreen, poses different challenges, and, most important, each is significantly different from unimpaired viewing.

Adobe Acrobat Accessibility Techniques

Some sites would hardly exist at all if they took down their PDF files (PDF stands for 'Portable Document Format'). This format is an incredibly useful format for some situations, providing a method to post content on the Web that will print exactly as the author intended it to. Creating PDF files is faster and easier than creating HTML files in many cases. This increases its allure for Web developers.

Affrontare l'Accessibilità

Questo libro risponde a due domande. La prima è "Perchè dovrei rendere più accessibile il mio sito?" E se non avete un sito web, questo libro non è per voi. La seconda domanda è "Come posso rendere il mio sito più accessibile?" Se non siete convinti della vostra prima risposta, non sarete di certo interessati alla seconda.

AHA: Audio HTML Access  

This report discusses the 'AHA' system for presenting HTML in audio for blind users and others who wish to access the WWW non-visually. AHA is a framework and set of suggestions for HTML presentation based on an initial experiment. Further experimentation and further revisions will be performed with the system.

AJAX and Screenreaders: When Can it Work?

We've all heard a great deal of buzz about AJAX in the last few months, and with this talk has come a legion of articles, tips, presentations and practical APIs designed to explore the possibilities and try to arrive at best-practice techniques. But, for all of the excitement and hype, still very little has been said on the subject of AJAX and accessibility.

Alt and Beyond: Making Web Graphics Accessible

Many developers still view graphics and accessibility as being on opposing ends of the web development scale. The truth is that including graphics in your documents does not mean your page has to be any less accessible. In fact, as we will see later in this article, graphics can be used to enhance the accessibility of a page. There are, however, a few key techniques that you can employ to ensure that you don't have to construct alternative 'Text-Only' documents. The web truly is the last frontier where we can treat all people equally with 'one size fits all' web documents. There is just a little bit extra we need to do to achieve this.

Alternative Interfaces for Accessibility

The key difference between user interfaces for sighted users and blind users is not that between graphics and text; it's the difference between 2-D and 1-D. Optimal usability for users with disabilities requires new approaches and new user interfaces.

Amex Woes Highlight Common PDF Accessibility Problem

American Express has come under criticism, and potential legal action, for the lack of accessibility of its credit card website. A blind customer of American Express credit cards found that Amex's change in the presentation of its online credit card statements from HTML to PDF format effectively prevented him from accessing his financial information online.

The Applicability of the ADA to the Internet

As the Internet has increased in prominence in all sectors of society, interested individuals have begun to question whether or not the Internet should be included in the regulations set forth by the Americans with Disabilities Act. Right now there is no explicit reference to the Internet in any of the language of the act.

Applied Theory: Working Toward an Accessible Web Site

With the passage of Section 508 and the efforts of the World Wide Web Consortium (W3C), interest in Web site accessibility continues to increase. Web designers and Web content developers are finding that knowledge in Web accessibility is becoming essential to be marketable to government contracts and private industry since accessibility is becoming a best practice, and in some cases a legal requirement, in Web development. This article is written for those who already have a general knowledge about the reasons for, and the techniques of, designing accessible Web sites. In this article, I will share the steps that I have taken to work toward transforming a Web site that I manage to one that is accessible according to the W3C recommendations.

Applying Color Theory to Digital Displays

For backgrounds behind text, use solid, contrasting colors, and avoid the use of textures and patterns, which can make letterforms difficult to distinguish or even illegible. Choose combinations of text color and background color with care. Value contrast between body text and its background color should be a minimum of about eighty percent.
