IA, tillgänglighet och skärmläsare : En studie om informationsarkitekturens koppling till tillgänglighet och hur det påverkar användare av skärmläsare

Sammanfattning: Previous studies indicate that visually impaired users of screen readers experience more difficulty interacting with websites when there is an absence of accessibility. The purpose of this study is to focus on IA components: organisation, labelling and navigation and accessibility guidelines recommended for screen readers from WCAG 2.1 to investigate the current status of accessibility regarding screen readers on Swedish websites. The websites that have been analysed are divided into three categories: government, target group-oriented, and commercial. These categories represent users’ possible everyday services. The study was conducted using a quantitative document study with an observation schedule and an univariate analysis. The results indicate that the government category had implemented most acceptable accessibility adaptations, however this was to be expected as it is regulated by the law of DOS. On the other hand, the commercial category implemented the least acceptable accessibility adaptations. This was expected as previous research has revealed that online stores have poor accessibility. Lastly the target group-oriented category had performed accessibility adaptations that were less acceptable than the government yet more acceptable than the commercial. The primary users of the target group-oriented category are visually impaired users, therefore, there were expectations of more and better implemented accessibility adaptations. The conclusion is that there are deficiencies regarding accessibility in the categories included in the study. It shows that the lack of accessibility can be linked to IA, as the implementation of accessibility adaptations represented how well the components had been used and applied.
