What is digital accessibility?
Digital accessibility refers to unrestricted access to content on the internet and to files and applications on your own computer. Media, learning content or websites are accessible or accessible if people can use them despite their impairments.
Disabilities are individual, therefore barriers are individual. Unfortunately, it is not realistic to prepare applications and content for all possible disabilities. In order to keep the work order clear and manageable, the achievement of accessibility has been standardized: Various standards and tests define what must be met for an application or content to be considered accessible. “Accessibility” is therefore an operationalized, testable measurement concept. It is a legally defined term that is based on uniform regulations and is therefore measurable - and, above all, enforceable. In contrast, the term “low-barrier”, which is sometimes used, is unspecific.
Digital accessibility includes these four principles:
- Perceivability: All content and operating elements are presented in such a way that people with disabilities can also perceive the information and structure.
- Usability: All content and control elements must be operable. Everything can be accessed, activated, closed and exited without a mouse.
- Comprehensibility: All content and operating elements must be easy to understand. The forms are clearly labeled, navigation elements are clearly identified.
- Robustness: All content and operating elements must be reliably interpreted by various assistive tools.
