Presentation given by Jonathan Hassell (Accessibility Editor, Digital Curriculum for BBC New Media) at eAccess 2007 conference.

Covers: how to make user-generated content (on YouTube, blogs, Facebook, or on comments on your own website) accessible through accessible content building tools and moderation; how multimedia (video and games especially) presents a real challenge to people who rely on assistive technologies (especially blind people); how multimedia formats (especially video) can itself be an accessibility aid to people with literacy difficulties or who use British Sign Language; how learning from the accessibility games special interest group (IGDA-SIG) and audiogames.net can suggest some new innovations in multimedia for blind people

  • 3. BBC & accessibility – a brief history
      • BBC long-term commitment to making its output as accessible as possible to all audiences to fulfil its public service remit
      • TV/radio:
        • body of experience within the BBC of disability issues
          • TV accessibility – subtitles, signing, audio-description
          • established programmes and audiences (e.g. See Hear, In Touch), moving towards mainstream (Desperados)
      • Online:
        • 1998: Betsie – text-only tool for web pages (still used by other sites - e.g. Newcastle City Council)
        • 2002: bbc.co.uk accessibility training course (with AbilityNet) and ongoing standards & guidelines
        • 2005-6:
          • Helped write PAS-78 accessibility commissioning guidelines from BSI & DRC
          • BIMA Award winning My Web, My Way accessibility help site to help users understand how to customise their computers (with AbilityNet)

  • 4. Web 2.0
      • characterised by…
        • User-Generated and collaborative content
          • Blogs
          • Social networking
          • Wikis
        • Rich Internet applications
          • use of AJAX, Flash etc.
        • [my addition] multimedia
          • audio, video, animation etc.
      • or, for a better definition, go to Wikipedia (the pre-eminent Web 2.0 site)

  • 5. Why Web 2.0 is going to change accessibility – UGC
      • let ’ s start with UGC…
        • the site owners used to be the people who created content
        • increasingly now it ’ s their users creating the content
      • how is this going to change things?
      • well, this used to be my main “ accessibility evangelism ” slide – how it used to be…

  • 6. Accessibility is a partnership
    • to make a website accessible, all of the following need to work together:
      • Website creators
      • Assistive technology creators (e.g. Freedom Scientific, ReadPlease)
      • Operating system creators (e.g. Microsoft, Apple)
      • Disability assessment agencies (e.g. AbilityNet, RNIB)
      • Browser creators (e.g. Microsoft, Opera)
      • comms via W3C-WAI…

  • 7. Why Web 2.0 is going to change accessibility – UGC
      • because of the DDA, the disabled/accessibility community has had many successes persuading site owners to make their content accessible...
    © BBC, 2007 Slide [email_address]
  • 8. Why Web 2.0 is going to change accessibility - UGC
      • but how do you persuade the everyday users of Blogs, MySpace or Bebo (or even worse, YouTube) to make their content accessible?
      • how do you make social networking available to all?
    © BBC, 2007 Slide [email_address]
  • 9. Why Web 2.0 is going to change accessibility - UGC
      • in case you think such places aren ’ t important…
        • blogs have been identified as changing election results (US 2004-6)
        • AbilityNet have an accessibility channel on YouTube
        • the BBC has just bought an island in virtual community Second Life
        • and many sites have a “ have your say… now with imaging… ”

  • 10. Why Web 2.0 is going to change accessibility - UGC
      • here it ’ s about the tools and the moderation
      • the tools:
        • does the content building tool include a mechanism for enabling users to include accessibility support? (link with the lesser-known ATAG guidelines from WAI)
      • the moderation:
        • will the moderators of content (if there are some) consider it important to ensure users include that accessibility support?
          • without DDA or potential commercial gain to help… where ’ s the argument to say it ’ s worth their while?
      • the BBC are looking at how we can do this…
        • we ’ re using the “ moderator adds the accessibility ” approach
    © BBC, 2007 Slide [email_address]
  • 11. Why Web 2.0 is going to change accessibility - multimedia
      • moving on to multimedia
        • the bulk of the content used to be text + graphics…
        • the content is moving on to incorporate
          • audio (podcasting)
          • video
          • animation
          • applications
          • games
      • how is this going to change things?
      • let ’ s look at that “ accessibility evangelism ” slide again...

  • 12. Accessibility is a partnership
    • to make a website accessible, all of the following need to work together:
      • Website creators

      • Operating system creators (e.g. Microsoft, Apple)

      • Browser creators (e.g. Microsoft, Opera)

  • 13. Why Web 2.0 is going to change accessibility - multimedia
      • Threats:
        • the accessibility chain doesn ’ t work any more...
        • find me the assistive technology that can make video or games accessible for blind children…
        • this is why new techniques are necessary (cf. WCAG 2)
          • the web ’ s less and less about HTML
          • it ’ s less and less about ATs which assume that (esp. screenreaders)
          • and it ’ s about the content… not just the controls
            • “ accessible multi-media browsers ” are useful, but how do you do ‘ alt-text ’ for a video?
        • and why we need to bring in other accessibility professionals, from:
          • TV (subtitling, audio description) and interactive TV
          • video games (which use it all)
    © BBC, 2007 Slide [email_address]
  • 14. Why Web 2.0 is going to change accessibility - multimedia
      • but it ’ s not all bad...
      • Opportunities:
        • these are huge, for many disabled people who sometimes get forgotten
          • WCAG doesn ’ t say much about learning difficulties, autism, Deaf…
          • but video, for many, is more accessible than text - why have “ Plain English ” when you can have TV?
        • e.g. rich-media can give us great opportunities to help Deaf people (BBC R&D)
      • get rid of the phrase “ it is/isn ’ t accessible… ”
        • replace it with “ it is/isn ’ t accessible to people with this disability ” ?
        • understand that sometimes you can ’ t please all of the people with one product…

  • 15. Why Web 2.0 is going to change accessibility - multimedia
      • but what about Blind people?
      • will this move from text to multimedia bring the same problems as the move from MS-DOS to Mac & Windows?
      • possibly, but help is at hand…
        • established media techniques – audio-description
        • new techniques - audiogames (more R&D from BBC jam )
