Application of universal design principles in the creation of websites oriented toward visually impaired persons

The subject of this study is to show the impact that applying universal design principles has on everyday work with web content for people with visual impairments. The first part of the study is an experiment using an eye tracker, comparing the effects of using high contrast or changing the font size on the subjects' efficiency in performing simple tasks. The second part of the study is a survey comparing the feelings of using a website strictly compliant with universal design principles and its counterpart containing noticeable errors. The eye tracking results were analyzed to assess time to first fixation, average fixation time, and time spent on a designated area of interest. The results indicate an increase in efficiency and comfort with digital content designed according to universal design principles.
