What is Accessibility?
Accessibility is the design of products, devices, services, or environments for people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e., unassisted) and "indirect access," meaning compatibility with a person's assistive technology (for example, computer screen readers).
Accessibility involves two key issues: how users with disabilities access electronic information and how web content designers and developers enable web pages to function with assistive devices used by individuals with disabilities.
For the user with a disability, the challenge is to identify tools that provide the most convenient access to web-based and other electronic information. For the web content designer/developer, the challenge is to remove the obstacles that prevent accessibility tools from functioning effectively. In many cases, these challenges are relatively simple to overcome, but sometimes the solutions require some additional thought and effort.
