Usability and Accessibility

What is Web Usability?

Usability consists of a set of methods created to maximize ease of use, in this case, a portal or internet pages.

What is Web Accessibility?

For the World Wide Web Consortium accessibility is the attribute through which “people with disabilities can perceive, understand, navigate and interact with the web, and can contribute to the web”.

Web Accessibility is translated by the set of rules used in the design and construction of an Internet page, so that it can be accessed by anyone, regardless of whether they have a disability or not.

Differences and relations between the two terms:

  • A website that is built with maximum accessibility benefits all users and not just those with a disability;
  • Accessibility is a subset of usability;
  • A website is not usable unless it is accessible;
  • Without accessibility there is no usability, but there is accessibility without usability.
  • The objectives of accessibility are to increase the inclusion of people with disabilities in the digital world.
