About people with disabilities
A problem in accessibility is the result of an interaction between a user and the content (or functionality) that he or she tried to access, use, perceive or understand but couldn’t because of a disability.
Looking beyond people’s disability, everyone is different and it would be meaningless to describe all the accessibility problems resulting from the content and functionalities of a site or web application lacking adaptability.
This first part focuses on what difficulties people will encounter during their experience or what kind of interaction will disrupt their experience.
