Have people with disabilities test your UI & UX
Have a sketch or wireframe?
If you have a sketch or wireframe, take it and talk through it with people with different disabilities. Explore how they solve problems. Understand their motivations and the way they think. Work with people that use voice recognition software to talk aloud about how they’d approach the interface and what voice commands they might give to accomplish tasks.
Have a Figma, Sketch, InDesign, or Adobe XD prototype?
Get people with low vision to review it. Even though it isn’t coded, you can still get feedback on colors, layout, interaction flows, and more.
Have a coded HTML prototype?
Get people that use a screen reader to run through the prototype and give you feedback.
