It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

For web developers to create functionally accessible web resources they need more than general guidelines and tools that provide them with lists of manual accessibility checks. Web developers need specific web accessibility techniques and tools that help them verify they have correctly implemented the techniques. The techniques also need to support the wider concepts of the web of interoperability and device independence. The CITES/DRES Functional Web Accessibility Best Practices provide developers with specific techniques and requirements to implement Section 508 and W3C WCAG 1.0 requirements. The use of the Functional Web Accessibility Evaluation (FAE) Tool and the Mozilla/Firefox accessibility extension provide free and open source tools to allow developers to verify they have used the best practices.

Web browsers and multimedia players play a critical role in making Web content accessible to people with disabilities. Access to Web content requires that Web browsers provide users with final control over the styling of rendered content, the type of content rendered and the execution of automated behaviors. The features available in Web browsers determine the extent to which users can orient themselves and navigate the structure of Web resources. The World Wide Web Consortium (W3C) User Agent Guidelines are part of the W3C Web Accessibility Initiative, the guidelines provide a comprehensive resource to Web browser and multimedia developers on the features needed to render Web content more accessibly to people with disabilities. UAAG 1.0 was developed over a period of four years and included extensive reviews to demonstrate that the proposed requirements can be implemented.

The WWW is rapidly becoming the medium of choice for communication in the new international economic, social and educational revolution the world is facing at the start of the next millennium. WWW based technologies are changing the way people communicate throughout the world, and the ability to use WWW based technologies is becoming an important literacy skill. People with the ability use WWW technologies and participate in the transformation and creation of new WWW information are going to have many more opportunities in this emerging society than people who do not. Universal design must be a part of these new technologies if people with a wide range of capabilities are going to have an equal opportunity to participate. People with permanent disabilities, people who are older, and people with temporary disabilities and people using technology that "impairs" them need to be considered if there is going to be equal access for all.

Gunderson, Jon, Gruetzmacher, George and Swanson, Naomi (1991): Legibility of Seven Segment Numeric LED Displays: Comparisons of Two Fonts at Various Distances. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 491-495.
The legibility of seven segment numeric displays was investigated for two different numeric LED fonts at five reading distances. An alternative font as proposed by Van Nes and Bouma (1980) was compared to the font used currently by many commercial products. Subjects performed a digit cancelling task as single digits were presented on the seven segment display at various reading distances. The error rate and response times for five reading distances from 8 to 25 feet were evaluated for a .3 x .188 inch LED display (VAS of 0.179 to 0.0573 degrees). The font proposed by Van Nes and Bouma was found to reduce errors by almost 50 percent at all but the longest viewing distance. This design information is valuable especially when designing medical equipment for critical care and operating room environments.

Gunderson, Jon (1991): Limits of Intelligibility of Accelerated Synthesized Speech by Inexperienced Sighted and Experienced Blind Listeners. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 496-500.
People with blindness who use computer systems cannot use the standard CRT display to access information presented by the computer. The main medium for people with blindness to access computers is through electronic speech synthesizers. One of the characteristics of computer users with blindness is to increase the speech rate of the synthesizer to rates more than double normal conversational speech rates. To the casual listener the increased speech rates seem unintelligible. There have not been quantitative measurements of this observed behavior to determine the limits of speech intelligibility and behaviors at high speech rates. This study is designed to investigate the limits of speech intelligibility of accelerated synthesized speech for both inexperienced and experienced listeners. The results of this experiment show that intelligibility decreases linearly with speech rate. There is no significant difference between the percentage of words correct between the experienced and inexperienced group. There is a significant difference in the number of words confused between the two groups. The lack of group effects in the percentage of words correct is due to a bimodal distribution of scores in the experienced group. While subjects in the experienced group clearly demonstrate the highest intelligibility the group also have some of the lowest intelligibility scores.
