Accessibility Arguments Revisited

Frontend has recently completed the delivery of the first version (1.1) of the Irish National Disability Authority (NDA) IT Accessibility Guidelines. In the course of our work for the NDA over the last year we’ve talked to a wide variety groups and individuals who have an interest in accessibility and as a result of their input, our approach has shifted a little. Here’s what we found out.

Accessibility Is Not Enough

A strict focus on accessibility as a scorecard item doesn't help users with disabilities. To help these users accomplish critical tasks, you must adopt a usability perspective.

Accessibility Meets Usability: A Plea for a Paramount and Concurrent User-Centered Design Approach to Electronic and Information Technology Accessibility for All  

This paper identifies challenges for a user–centered design process with respect to infusing accessible design practices into electronic and information technology product development. Initially, it emphasizes that when user–centered design is paramount and concurrent with accessible design, electronic and information technology can be accessible for all. Next, it provides an overview of the Americans with Disabilities Act (ADA) Section 508. Last, it provides basic accessible design heuristics that can be integrated into the design process. It concludes with recommendations for a paramount and concurrent user–centered design approach to product development.

Accessibility Redefined  

Accessibility has come a long way. Not only most public places but even many private areas now claim to be 'accessible'. However, this term usually implies that a person in a wheelchair is able to get to the inside of a venue. This is not enough. If I am using a wheelchair, I would like to be completely autonomous and move around freely. I don’t want to have to go along a long dark corridor to use a service lift in order to get to another floor. Although I always appreciate it, I don’t want to have to count on the generosity of passersby to help me open a door or push my wheelchair up a slope. My only wish is to blend in with other people, and enjoy life as much as anyone else.

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.

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.

Beyond Accessibility: Treating Users with Disabilities as People

With current Web design practices, users without disabilities experience three times higher usability than users who are blind or have low vision. Usability guidelines can substantially improve the matter by making websites and intranets support task performance for users with disabilities.

Blind and Low Vision Users

When we come to accessibility of web design, we will say that accessible web design is a sign of good web design. A lot of the information on the Web is not accessible to people with disabilities because of poor design. While many web site managers and developers accommodate various browser constraints, most of them do not realize that they are developing sites that people with disabilities have difficulty in navigating, or in many cases, cannot navigate at all.

Bridging Usability and Aesthetic Design of Wheelchairs

A wheelchair provides transportation for the disabled, independence and self-sufficiency to someone who would otherwise be completely dependent on others. But is functionality the only aspect of a wheelchair worth contemplation? Should we not evaluate the design aesthetic of wheelchairs to the same extent that we analyze the design of other useful and purposeful objects?

Cognitive Behavior Learning Disabilities: Being Different Shouldn't Mean Being Discriminated Against

I view my son's early school years in the 90s as a nightmare. I asked if my son could submit homework done on the computer due to his awful handwriting - weren't his ideas the key issue? - and 'NO!' was the reply.

Color Vision Confusion

Color blindness is mostly neglected, even most of the people do not consider this as a serious problem. However, color blindness can be a problem that disrupts many tasks.

Designing for Users With Cognitive Disabilities

Users with cognitive disabilities interact with technology in different forms. Designers need to understand the deficits of users with cognitive disabilities in order to design materials that are accessible to those users. This paper provides an overview and analysis of the current state of service to those with cognitive disabilities, and makes practical suggestions on design issues, as well as suggesting further areas for research.

Evaluating Web Sites for Accessibility

This document outlines approaches for preliminary review Web site accessibility, and for evaluation of conformance to the Web Content Accessibility Guidelines 1.0. While it does not provide checkpoint-by-checkpoint testing techniques it does include general procedures and tips for evaluation during development of Web sites, and for monitoring of established Web sites. Other resources will be developed for in-depth compliance testing. The measures described here are intended to supplement an organization's existing procedures for content management and quality assurance on their Web sites. For information about why making Web sites accessible is important read the Introductions on the WAI Resources page.

Facts and Opinion About Fahrner Image Replacement

Fahrner Image Replacement and its analogues aim to combine the benefits of high design with the requirements of accessibility. But how well do these methods really work? Accessibility expert Joe Clark digs up much-needed empirical data on how FIR works (and doesn’t) in leading screen readers.

General Concepts, Universal Design Principles and Guidelines

People who could benefit from more universal designs include many both with and without disabilities. In some cases, people may experience difficulty in using products purely as a result of the environment or an unusual circumstance. Beneficiaries of universal design include: * People in a noisy shopping mall who cannot hear a kiosk * People who are driving their car who must operate their radio or phone without looking at it * People who left their glasses in their room * People who are getting older * People with disabilities * Almost anyone In order to design for the general population, it is important to understand the diversity, problems, tools, and abilities of its members.

A Guide for Website Developers About How to Accommodate Users with Low Education, Low Motivation

Users with low education are users who have obtained limited level of education. These educationally disadvantaged people acquired and applied complex reasoning, but the lack of basic reading comprehension and communications skills hinder their success in education and skilled occupations. Low level of education effectively equals to functional illiteracy. Even though there is a significant increase in Internet use for individuals with elementary education (129%) from 1998 to 2000, only 9.1% of those with elementary education versus 75.5% with Bachelor's Degree or more uses the Internet [2]. More than one out of five adult Americans are functionally illiterate, and their ranks are swelling by about 2.3 million persons each year. Nearly 40 percent of minority youth and 30 percent of semiskilled and unskilled workers are illiterate [1]. It is hence necessary to address website accessibility issues pertaining to this group of users.

A Guide to Making Documents Accessible to People Who Are Blind or Visually Impaired

This document contains a comprehensive discussion about how to make print and electronic information available to people with visual impairments in a variety of accessible formats. Consumers who have limited vision or are totally blind have unique access needs. These needs depend on the amount of vision each person has for reading. Some people have usable vision, allowing them to read large print. Others choose to read braille on paper, while a third group prefers to use a computer with synthetic speech, or refreshable braille display, to read electronic documents.

Helping Low-vision and Other Users with Web Sites That Meet Their Needs: Is One Site for All Feasible?    

For this study, we recruited low-vision users with a variety of vision problems who need software to magnify computer text. Although we did not systematically recruit for specific vision problems, the fact that our users had different needs gave us one of the most critical insights in this study: The needs of low-vision users are too diverse for simple solutions to Web accessibility and usability. We show a few ways in which today’s Web sites are missing the needs of all low-vision users and provide guidelines for fixing those problems. However, the diversity of vision needs and the resulting adaptations that low-vision users require mean that there are no simple solutions to making Web sites work for everyone. In this article, therefore, you will not find many simple guidelines. Instead, we raise a critical issue and suggest a 'vision of the future' solution.

Human-Computer Interaction for Kids  

How is designing computer software and hardware for kids different from designing for adults? At the time of this writing, little formal research has been done on this topic. Most research done to date has focused on designing educational software, and evaluation is primarily of learning outcomes, not usability. However, usability is a prerequisite for learning.

Improving Accessibility for Motor Impaired Users

The unique requirements for motor impaired web users can often be overlooked or poorly implemented. Motor impairments can be caused by a stroke, Parkinson's disease, Multiple Sclerosis (MS), a physical disability or even a broken arm. This group of users essentially have limited or no ability to use a mouse.

Increasing the Accessibility of the Web through Style Sheets, Scripts and 'Plug-ins'

The W3C WAI Page Authoring Guidelines (Vanderheiden, et al, 1998a) contains nineteen general concepts that Web page authors should follow to make their pages more accessible and usable, not only to people with disabilities, but for newer page viewing technologies (mobile and voice), for electronic agents such as indexing robots, and etc. In this paper/presentation, we will talk about and demonstrate how scripts and style sheets can be implemented today, and still work on systems that do not support scripts and style sheets ('Transform gracefully'). We also talk about and demonstrate how the data in a table can be presented and navigated both via scripting and by an accompanying application ('Context and navigation').
