Motivation

TODO: Describe why viewing talks directly in the browser is desirable

Technology Requirements

  • R1: Viewing talks with slides directly on the web
  • R2: Not requiring visitors to have Open Office installed
  • R3: Not requiring people to download the presentation
  • R4: barrier-free, (e. g. text view of slide-images, display transcript of audio)
  • R5: Support for all common browsers, including older browsers that are still in common use
  • R6: Support audio
  • R7: Audio is optional
  • R8: Support for small display screens (e. g. tablets, mobile phones)
  • R9: Should work without flash plugin and without JavaScript but may use these technologies if available


What is wrong with the standard html export in Open Office Impress ?

  • ok R1
  • ok R2
  • ok R3
  • fail R4: Requires Frame-Support in Browser. There is a html view that would work without frames, but it's not reachable from the start page.
  • unknown R5
  • fail R6: For audio an embed-tag is created which only works if the files are saved to disk but not in the world wide web
  • ok R7
  • fail R8: bulky frameset, slide images is not resized but gets scroll bars
  • fail R9: requires JavaScript for navigation



Approach

  • Use OpenOffice HTML-Export as base
    • with frames
    • with notes (if there are notes)
    • browser colors
    • black arrow icons without borders
