A Case for Usability and UX Testing

4 Mar 2022

“Nothing About Us, Without Us”

If your website hasn’t been tested by real assistive technology users, how do you know it’s truly barrier-free for people with disabilities? You really can’t.

That’s why it’s important to include people with disabilities in your web design and accessibility remediation process. Usability/UX testing is your opportunity to have real users test your website, and provide feedback about their experience and any issues they ran into when trying to navigate your site.

Why are Usability and UX testing critical for accessible web design?

When it comes to accessibility, listen to people with disabilities. Don’t just take a developer’s word for it.

Usability and UX testing are particularly important when designing accessible websites because people with disabilities have unique user experiences.

Automated scans and manual audits simply can’t replace input from people with disabilities–the true shareholders of your accessibility project. Usability/UX testing, done by real assistive technology users, is, key to ensuring that everyone has a barrier-free experience on your website.

After completing a manual audit and making any necessary remediations, you may be tempted to call it good… but wait! Don’t skip over UX testing.

Are you sure it can be used with iOS Voiceover? What does a user journey look like for someone navigating by keyboard control? Will moving elements be too distracting for people with cognitive disabilities?

These are some of the questions that can get answered during Usability and UX testing.

Assistive Technology

Voiceover/screen readers, keyboard controls, and speech-to-text software are examples of assistive technology–aka technology used by disabled people to help them complete tasks. Blind and visually impaired people often use software like Voiceover or JAWS to read out the contents of their screen. While someone with limited mobility may instead rely on keyboard controls, sip-and-puff devices, and speech-to-text software to use their computer.

Your website needs to be usable with the full range of assistive technologies to be considered truly accessible… and you may be surprised how many different types of assistive technology are in use.

Common types of assistive technology include:
  • Screen readers
  • Screen magnification software
  • Speech input or speech-to-text devices
  • Head-pointers or motion/eye-tracking
  • Refreshable Braille displays
  • Sip and puff
  • Keyboard Control
  • Single switch entry devices
  • Alternative input devices

Hiring real users of these assistive technologies is simply the best way to ensure your website is truly accessible. Additionally, there are numerous business benefits to conducting this type of usability/UX testing.

Benefits of Usability and UX Testing:

  • Identify accessibility issues that might have been missed by automated scanners and during manual auditing.
  • Uncover other barriers and areas of confusion to improve overall user experience and ease of use.
  • Gain a deeper understanding of how people with disabilities might use your site/product.
  • Increase traffic to your site while maximizing ROI by including users throughout the process.
