Accessibility on the Web: The Big Picture

26 June 2020

What is A11Y and Who is it for?

Making your app or website accessible means making it usable for all people regardless of their limitations. Those limitations often are but aren't exclusively what we consider disabilities. Those can be grouped into roughly 4 categories:

  • Visual Impairments (e.g. color-blindness, blindness)
  • Motor Impairments (e.g. missing or paralyzed limbs)
  • Neurological Disorders (e.g. autism, learning disabilities, epilepsy)
  • Hearing Impairments (e.g. deafness, tinnitus)

According to the WHO World report on disability around 15% of the world's population deals with some sort of permanent disability. And this excludes people who have temporary or situational disabilities such as: a broken arm, lost their glasses, ...

These people actually have a legal (and moral) right to access your app/website.

Non-Default Users

There's another category of users though that fall under the accessibility umbrella that you should cater to. I call these 'Non-Default Users'. With very, very heavy sarcasm though. They are in contrast to the 'Default User' who has the following traits:

  • white
  • heterosexual
  • cis-male
  • aged between 20 and 45
  • tech savvy
  • are fluent in English
  • have a Christian/Anglo-Saxon first and last name
  • live in an English-language (or at least 'Western') country
  • have the newest/fastest devices
  • always have a great internet connection with unlimited data
  • have 'Western' values (whatever that is...)
  • right-handed
  • of average height and limb size
  • calm, rational and collected

This persona is generally what apps and websites coming out of silicon valley and all the other big tech hubs in the 'West' have as a target user. Technically, catering to people who aren't on the disability spectrum but don't fall into the 'default user group' isn't part of accessibility but instead 'inclusive design' but in my experience those two go hand in hand.

Why Should You Care?

Reason number one: Because it's the right thing to do.

You'd think that would be a good enough argument but unfortunately management is usually like: "If we spend all our time making our app accessible instead of launching it we will have 0 users". While I get the sentiment, getting to a base-level of accessibility is usually not a lot of effort. Accessbility doesn't mean that your app needs to function 100% the way it does for people without accessibility aids. Just that it's 'accessible' (i.e. usable).

Having your app/website not usable also leaves you at the risk of getting sued (just as Beyoncé did a while back). The fear of getting sued usually makes management listen very closely.

While there's no official guidelines on how accessible your website needs to be to not get sued there are WCAG Success Criteria that have been adopted as more or less the legal standard. The average app or website should comply with the AA level whereas certain government platforms need to comply with AAA.
