About DVD usability

  • Every DVD has certain features as a default
    • UDF Bridge, a combination of UDF and ISO 9660 file formats
    • Files and Folders: VIDEO_TS and AUDIO_TS folders, containing VIDEO_TS.IFO and AUDIO_TS.IFO files
    • 6 different link behaviors between menus and timelines
  • In this work, DVD usability is analysed considering mostly the user interface issues
    • Hardware issues get much less attention than user interface design
  • The subject has not been researched that much so far
    • Source literature deals more with usability for example in the Internet
    • The bulk of the information comes from the end users of DVDs
slide4

The Employer and the Customer

  • Vantaa City’s Media Center
    • The employer
    • A relatively new media-house that among other things have DVD productions
  • Heureka
    • Heureka’s next DVD will be made by the Media Center, and it is used to market a music exhibition
    • Finland’s only Science Centre
    • DVDs quite new concept to Marketing Department
slide5

Work and Research Goals

  • Guidelines for good DVD user interface design
  • Information on how good is the platform compatibility of a DVD made in the Media Center
  • Heureka’s music exhibition DVD’s user interface script
  • Information on the use of DVDs in various science centers’ marketing
slide6

Research Methods

  • Hardware compatibility by testing
    • Nine different platforms
    • The test DVD was made in the Media Center in 2004
  • An HTML questionnaire form about DVD usability
    • A request to participate into the questionnaire was sent to a group of students and young adults
    • The questionnaire consists of six sections, of which the first five talk about the user interface and navigation issues
      • Navigational steps
      • Buttons & layout
      • Menu background sounds
      • Visual design and elements in menus
      • Features
      • Hardware usage and compatibility issues
  • The research on the use of DVDs in science centers’ marketing is done also with an HTML form
slide7

Results / Conclusions

  • The hardware compatibility test’s DVD worked well enough in every testing platform
  • The Questionnaire was answered by approximately 29 people
  • About navigation:
    • A DVD’s navigation scope should be between 2 and 4 steps
    • Buttons rather as text with an icon or text alone
      • They ought to be either at the center or at the bottom of the screen
    • The layout between menu windows should be consistent
    • Most of the navigational problems derive from bad menu design
    • Menu background sounds are mostly accepted
    • What elements there should be are text, background image and/or background color, and 3-4 basic layout colors
slide8

Results / Conclusions

  • Popular features
    • subtitles, surround sound, scenes, extras
  • Hardware usage and compatibility issues
    • The most popular platforms are basic DVD player and computer
    • Most of the questionnaire participants had experienced problems with hardware 1-3 times
    • The fact that some DVDs are not designed for every platform is the worst problem (bad production tools, regional code issues)
  • Preferably 2-4 navigational steps
  • Buttons rather as text with an icon or text alone
  • Menu background sounds are tolerated or approved
  • Popular features
    • subtitles, surround sound, scenes, extras
  • Desired elements
    • text, background image and/or color, 3-4 basic layout colors
  • Hardware
    • The most popular platforms are basic DVD player and computer
    • Most of the questionnaire participants had experienced problems with hardware 1-3 times
    • The fact that some DVDs are not designed for every platform is the worst problem (bad production tools, regional code issues)
