Why companies are making websites accessible for the blind?

Accessibility Testing

Though numbers are difficult to estimate, recent studies have found that about one fifth (20%) of all people have some kind of disability. While not all disabilities affect a person’s ability to use the Web, we must recognize that a significant portion of the population with visual, hearing, motor or cognitive disabilities are unable to access the Internet by traditional means. As information providers, we are obligated, both ethically and legally, to address the needs of people with disabilities when putting content on the Web.

Web accessibility companies are the solution which answers the motivation to accomplish the goals of

  • Moving beyond technical accessibility
  • Focusing on the principles of accessibility
  • Testing approach for web accessibility
  • Accessibility Understanding the user's perspective and needs

Before going deep into this topic, let’s understand the term Web Accessibility?

Web accessibility means that specially enabled people can use the Web. Building accessibility websites means facilitating disable people to use e-commerce, educational apps.

All disabilities that affect access to the Web encompass in web accessibility, including visual, auditory and physical, speech, cognitive and neurological disabilities. Millions of specially enabled people are finding difficult to use their Web. Currently, most Web sites and Web software have accessibility barriers that make it difficult or impossible for many specially enabled people to use the Web.

A key principle of Web accessibility is to evaluate the web sites that are flexible to meet the social factors, technical factors, legal and policy factors. The Websites an increasingly important resource in many aspects of life: employment, government, education, e-commerce, health care, recreation and more. It is essential that the Web be accessible in order to provide equal access and equal opportunity to specially enabled people.

Factors in a Business Case for Web Accessibility

Social Factors addresses the role of Web accessibility in providing equal opportunity for specially. Enabled people; the overlap with digital divide issues; and benefits to people without disabilities, including older people.

The industrial and technical facet

Enabling content on different configurations and being prepared for advanced web technologies, maintenance time, interoperability, quality, reducing site development reducing server load, these points’ address in technical factors.

Financial Factors

Pay attention to the financial benefits of increased website use, for example, from search engine optimization (SEO); direct cost savings; considerations for initial costs and on-going costs; and ways to decrease costs.

Legal and Policy Factors

In these terms, addresses the needs for accessibility web design from governments and other organizations in the form of laws, policies, guidelines, directives, regulations, standards, communications, orders or other types of documents.

Challenges

  • Only accessibility supported technologies and web Accessibility Company can be relied upon for accessibility. It further states that the technology is accessibility supported only when the user’s assistive technology will work with it. Since no list of supported technologies is provided or any formal way to measure if the technology is supported or not, this causes a challenge.
  • It is believed that around 80% of the criteria are testable by humans. However, the authors show that some of the descriptions of the techniques for testing cause confusion.
  • Following a success technique does not mean that a barrier not exists.
  • Rich Internet application like flash, a shockwave that relies heavily on graphics, animation, and colors makes a nightmare for accessibility.
  • Extensive colors are used in web applications; sometimes colors are used to announce special information and even to require user interaction.
  • • High band width and faster networks

Risks

  • The role of the web developer to know web accessibility development process and develop coding feasibly
  • Web developers and QA testers themselves tend to know little about accessibility and should have a twofold knowing each other’s role
  • Accessibility testing can be rigorous not only because specialized knowledge but also with specialized tools
  • Testing is further complicated by the difficulty of yielding definitive results
  • Validations tools can be validated against a certain standard and will either pass or fail
  • Obligation to understand the different types of accessibility issues

Web Accessibility Evaluation Tools

These tools are software programs or online services that help determine if a website meets accessibility guidelines. Accessibility web design and its evaluation tools can significantly reduce the time and effort to evaluate websites and also determine the conformance of websites to accessibility checks which can be executed automatically and effectively assist reviewers in performing accessibility checks which need to be evaluated manually. Remember, no tool can automatically determine the blind accessibility of websites. They can only assist in doing so, for the following reasons:

  • A lot of accessibility checks require human judgment and must be evaluated manually.
  • Operated by inexperienced evaluators who don’t have the capabilities and are not aware of the limitations of these tools.
