Summary

A survey was conducted targeting 25,000 visually impaired people. According to International Classification of Diseases (ICD), they classified the impairment to 6 categories: 1) blind without light perception, 2) blind with light perception, 3) visus worse than 0.05, 4) visus worse than 0.1, 5) visus worse than 0.3, 6) visus worse than 1.0. 61% of the participants were visually impaired by birth. The authors asks 16 questions regarding their reading experience: media format, problems, wishes for new assistive technology.

Four key issues in reading experience


  • Structure Overview: All participants wanted a better overview over the structure. Specifically headings > input fields, lists > tables > bookmarks > paragraphs > graphics.
  • Content Overview: skimming fast over the information. A faster content overview is more preferred than structure overview [Note: the authors miss number here.]
  • Usability of Assistive Technologies: Screen readers have different key sequences to control them.
  • Accessibility: All participants mention that they get documents that are not accessible for them.
