The Right Way to Make Information Truly Accessible
In the previous article, we talked about input – that is, how users send information to a system. Now it's time to talk about the other side of the equation: output. In other words — how the system returns information to the user.
Just as not everyone has the same ability to send input (touch, keyboard, voice, etc.), not everyone has the same ability to receive output – to see, hear, understand, or feel it.
Supporting Diverse Output = Equal Access
- A user who is fully blind – relies on screen readers or Braille displays to read text.
- A user with a language or cognitive difficulty – needs plain language or clear visual output.
- A Deaf user – won't hear an audio alert, but can see it through a clear visual indicator.
- A user with epilepsy – needs output free of flashing or overly intense motion.
Why Does This Matter?
Because your users don't choose their limitations, but they do choose whether to stay on your website or app.
And if they can't understand what's written, hear the instruction, or read the message – they simply won't stay.
It's Much Simpler Than It Sounds:
- Make sure all text can be read aloud by screen reader software (using semantic HTML).
- Don't hide critical information inside images – use clear ALT descriptions.
- Don't rely on audio-only output – always add a visual indicator.
- Support Braille output through full compatibility with standard screen readers.
- Maintain a clear content hierarchy – so information is presented in a logical order.
In Summary
Supporting diverse output options is a critical component of an accessible user experience.
Just as you wouldn't restrict how a user types or makes selections – don't restrict how they consume information either.
Glossary:
- Braille Display: A physical device that translates on-screen text into a row of raised dots that can be read by touch by people who are blind.
- Screen Reader Software: Software that reads on-screen content aloud, enabling people with visual impairments or blindness to navigate and understand digital information.
