Why Accessibility?
Why?
Accessibility is important because it allows everyone to be included. It also keeps one from be sued for excluding others. According to the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD), accessibility is considered a human right. Not to mention, accessibility is beneficial to society, as it allows everyone to be treated as a whole.
How?
The most known accessibility concept is the ‘Curb-Cut Effect’. The curb-cut effect is when a person who is not disabled uses an accessibility feature to their advantage. For example, a person might not know English as their first language and has a hard time understanding a movie. He or she will use the closed-caption feature so that they can better understand the lines in the movie. More information on the curb-cut effect can be found here: Wikipedia.
