According to Jacob Neilson “Usability is a quality attribute that assesses how easy user interfaces are to use. The word “usability” also refers to methods for improving ease-of-use during the design process. “. But what about when you are testing a visually impaired user? How do you accommodate them? What are the challenges that you encounter when conducting testing with people with disabilities; how do you over come them?

In 2001, Jakob Nielsen said the first rule of usability is not to listen to users. He wrote this in the context of user preferences and desires—users aren’t always the best judges of what a design should be—but there is a lot of value in analyzing user feedback in the context of usability testing.

When inviting visually impaired users to test a product, it’s essential to understand how the testing process differs, and the reasons behind the changes.
