Accessibility vs. Usability – Where is the Dividing Line?

Abstract

Web accessibility for people with disabilities may be looked upon as the overcoming of barriers that make it difficult for them to use Web resources. Web accessibility for people with disabilities may be looked upon as the overcoming of barriers that prevent them from using these resources. Web accessibility can be improved through the use of assistive technologies in some cases by enabling access through alternative or enhanced modes. Web usability has been popular for longer than Web accessibility and theory, techniques, and guidelines relating to Web accessibility are more recent than those of Web usability. Accessibility could thus be considered as having a narrower scope than usability. Accessibility of Web resources by people with disabilities, which involves both access and use, is best supported by a combination of a set of accessibility guidelines and a set of usability guidelines.
