The ultimate goal of usability testing is to ensure that users have the best possible experience using an interface. This is a tall order, so it helps to have a diverse group of users testing the interface. One important group to consider is users with visual disabilities, since they use most technology in very different ways than non-disabled users. 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.
