  1. News sites / television sites • dr.dk • bbc.co.uk • cnn.com ___ Two sites are sites of national broadcasting corporations We assume that they put some effort into the site’s accessibility and usability

  2. Method and task Task To find the news story about the bombing in Pakistans (at the Marriott Hotel) (which took place some days ago) Accessibility Report from CynthiaSays Usability Doing the task (having heuristics in mind)

  3. Cynthiasays • A lot of errors on alt attributes • dr.dk did not pass the ‘provide link to a plug-in or applet’-test • cnn.com did pass this test • dr.dk fails: same link text to different ressources • dr.dk has no meta-elements (description, keywords and language in <head>)

  4. Is ’Cynthiasays’ useable? (1/2) To somedegree Public service media’s sites ought to supply: veryaccessable sites • i.e.altattributes • Alternative access/Links to pluginsif not alreadyinstalled Thistool points out thesethings To the degreethat the HTML canexpressaccessibility

  5. Is ’Cynthiasays’ useable? (2/2) Flaws & Limitations • It is mostlyCodeerrorswhichare not easy to understand • Howsevere is it that the alt attributesare missing? It is a verymechanicaltool That the code is gooddoes not nessecarilymeansthat the site is accessable i.e. Does not sayanythingaboutenlarge/decrease font tool (it is not expressed in the mark up rules)

  6. Alt attribute: ”Finland”

  7. Usability – bbc.co.uk • same color for the headers, the titles and the tabs -> different to tell some information apart(w3.orgs style sheet validator) • Broken links • A lot of arbitrary changes in design/colours • Lack of consistency and status

  8. BBC – front page

  9. News story about the bombing

  10. Relation betweenusability and accessibilty The accessability report can point out some usability problems • Alt attributes + alternative access flaws Other accessability reports can point out • broken links • Flaws in design (i.e. using same colors for links and text) All very useful on large sites

  11. Relation betweenusability and accessibilty Accessibility report cannot replace heuristic usaility report • i.e. user control and freedom • Match between system and the real world • Visibility of system status You would have to look at the site to check up on these issues
