  • 1. Bruno Splendiani, Mireia Ribera Adaptabit Group – University of Barcelona DSAI Conference 2013 - 13/11/2013
  • 2.       Introduction Our work Methodology Results Conclusions Further work Bruno Splendiani (2013) – splendiani@ub.edu 2
  • 3.  Accessibility scientific literature published by computer science journals  Computer science researchers play an active role in digital accessibility research Bruno Splendiani (2013) – splendiani@ub.edu 3
  • 4.  Many computer science subjects rely on visual resources such as graphs, diagrams and charts.  Visual content in computer science academic papers is a critical information source  Readers with visual impairments cannot access graphical information Bruno Splendiani (2013) – splendiani@ub.edu 4
  • 5. Sources: [1 -4] Bruno Splendiani (2013) – splendiani@ub.edu 5
  • 6. “If I can’t see the image I read its description”  Recommended by the Web Content Accessibility Guidelines  Incorporated to the publishing workflow guidelines of Bruno Splendiani (2013) – splendiani@ub.edu 6
  • 7.  Readers  Access to the content  Publishers  Advantages in article retrieval  Fulfil accessibility regulations  Comply with social responsibility Bruno Splendiani (2013) – splendiani@ub.edu 7
  • 8. Analysis  Do actual practices of image submission fulfil basic recommendations on accessibility? Proposal  What should be done for including accessibility practices and principles in the submission process of academic journals? Bruno Splendiani (2013) – splendiani@ub.edu 8
  • 9. 10 journals in computer science in JCR Follow accessibility policy? Submission policy and guidelines related to the visual content? Follow international guidelines on image submission? Bruno Splendiani (2013) – splendiani@ub.edu 9
  • 10. 1 paper for each journal in PDF version Are figures “readable”?      Image format Color contrast and coding Label font type and size Minimum resolution Minimum dimensions Do figures have alternative text? Source: [4] Bruno Splendiani (2013) – splendiani@ub.edu 10
  • 11. Bruno Splendiani (2013) – splendiani@ub.edu 11
  • 12.  The practices do not fulfill basic recommendations on accessibility  Images lack alternative descriptions  Lack of consistency between image submission policies and their application Bruno Splendiani (2013) – splendiani@ub.edu 12
  • 13. The visual information of computer science articles is not accessible to people with visual disabilities Bruno Splendiani (2013) – splendiani@ub.edu 13
  • 14. Common set of international guidelines for image submission universal accessibility improved Easier graphical authoring: shared guidelines Bruno Splendiani (2013) – splendiani@ub.edu 14
  • 15. Start from existing guidelines on image description Bruno Splendiani (2013) – splendiani@ub.edu 15
  • 16. Some depth work done in common charts (bar, line, pie...) But NO clear foundation for describing other types of images The image is…. It shows…. Panel a shows.. Panel b shows.. Legend shows… Bruno Splendiani (2013) – splendiani@ub.edu 16
  • 17. Currently computer science articles are not accessible to everybody  Accessibility of scientific papers and their figures should gain relevance in computer science research   Research in the field will  improve image accessibility  Improve retrieval  Improve the efficiency of the submission process Bruno Splendiani (2013) – splendiani@ub.edu 17
  • 18. Domain - specific Science Technology Engineering Mathematics  Graphic type - specific Illustration Diagram Photograph ………  Bruno Splendiani (2013) – splendiani@ub.edu 18
  • 19.  Adapted to the image role/function within the article  Support the article results?  Offer a visual example?  Show numerical data?  Emphasize special details? Bruno Splendiani (2013) – splendiani@ub.edu 19
  • 20. In the context of all image-related textual information Source: [5] Bruno Splendiani (2013) – splendiani@ub.edu 20
  • 21.  Linked to the publishing workflow  Supporting formats  Recommendations in submission system  Automatic image check (contrast, resolution, font size..)  Alt text check Bruno Splendiani (2013) – splendiani@ub.edu 21
  • 22. Questions? splendiani@ub.edu Bruno Splendiani (2013) – splendiani@ub.edu 22
