Next Generation Internet accessibility pages
The most used accessibility guidelines in the world are the Web Content Accessibility Guidelines (WCAG). They are used as foundation for many other technologies. The guidelines are divided into four principles for accessibility. To be accessible, your end result should be (source: WCAG2.1):
- Perceivable – users must be able to perceive information that is presented to them. Even if they are blind. For example, if you place an image, be sure to describe this image for persons who are blind.
- Operable – users must be able to operate all elements of an interface.
- Understandable – users must be able to understand the information given by a product and also how to operate the products’ interface elements
- Robust – content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.

Legal information about accessibilty
Most countries have legal requirements for accessibility, both for websites, software and for electronic equipment. But also for the physical environment including roads, buildings, public transport, etc.
- W3C offers a broad overview of worldwide policies regarding digital accessibility. Some include accessibility in a more general sense than just the digital domain: https://www.w3.org/WAI/policies/. HAN is currently updating this resource.
