Usability Testing for Users with Disabilities

Since the Middle Ages are long in the past, everyone should understand that each person is unique and, some people have specificities, and no one is a robot. This uniqueness can lead to a change in the perception of the world and should be taken with great tolerance.

It often happens that a healthy person is not always able to notice someone having problems with hearing, vision, ability to read, etc. When developing a site, it is worth considering that there are many such people.

For instance, the complexity of site navigation can sometimes repel users. So, take into account that reducing screen manipulations and improvement of the interface will be beneficial not only for older people and people with hand motility problems or other body control issues but also for any site visitor.

Most often, when searching for information, a user finds it in text format. In this regard, the content must be well readable. Problems with perception can be of different types, from minor or severe visual impairment to dyslexia. For a website, it is best to use the contrast rule. That is, it is desirable that the background color does not merge with the font. The font must be large enough and legible.

It is also worth remembering that people’s perception of colors varies, so if you use any questionnaires or other elements with an emphasis on color, it is better to add a description to them. Speaking about texts, one of the most important things cannot be omitted – subtitles. If you are posting a video, adding subtitles to it will be a huge advantage for you.

Screen readers are of great help for people with visual impairments. This function assists them in navigating an app or site without changing its functionality. So, it is crucial to provide high-quality texts, with correct abbreviations and several contrasting fonts, while adding descriptions of pictures, photographs, and other graphic components.
