What is Web Accessibility?

What is Web Accessibility?

Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them. More specifically, people can:

• perceive, understand, navigate, and interact with the Web
• contribute to the Web

Web accessibility encompasses all disabilities that affect access to the Web, including:

• auditory
• cognitive
• neurological
• physical
• speech
• visual

Web accessibility also benefits people without disabilities, for example:

• people using mobile phones, smart watches, smart TVs, and other devices with small screens, different input modes, etc.
• older people with changing abilities due to aging
• people with “temporary disabilities” such as a broken arm or lost glasses
• people with “situational limitations” such as in bright sunlight or in an environment where they cannot listen to audio
• people using a slow Internet connection, or who have limited or expensive bandwidth

Why accessibility is important

Blind and visually impaired make up 285,000,000 people according to the World Health Organization (June 2012) with 39,000,000 categorized as legally blind and the remaining 246,000,000 visually impaired. Deaf and hearing impaired make up 275,000,000 (2004) in the moderate-to-profound hearing impairment category.

To put these in perspective, the population of the United States of America is 315,000,000 (January 2013).

Disabilities can also be conditional. A broken arm, a loud restaurant, harsh glare, not speaking the local language—all are examples where someone may benefit from accessible practices.
