Updated video accessibility demo

Posted in Digital Media, Open Source, code, open codecs, standards, video accessibility by silvia on the September 14th, 2009

Just a brief note to share that I have updated the video accessibility demo at http://www.annodex.net/~silvia/itext/elephant_no_skin.html.

It should now support ARIA and tab access to the menu, which I have simply put next to the video. I implemented the menu by learning from YUI. My Firefox 3.5.3 actually doesn’t tab through it, but then it also doesn’t tab through the YUI example, which I think is correct. Go figure.

Also, the textual audio descriptions are improved and should now work better with screenreaders.

I have also just prepared a recorded audio description of “Elephants Dreams” (German accent warning).

You can also download the multitrack Ogg Theora video file that contains the original audio and video track plus the audio description as an extra track, created using oggz-merge.

As soon as some kind soul donates a sign language track for “Elephants Dream”, I will have a pretty complete set of video accessibility tracks for that video. This will certainly become the basis for more video a11y work!

    Yes it is the FF bug unsolved… a similar situation as the bug: https://bugzilla.mozilla.org/show_bug.cgi?id=93149 (*2001*)
    about the in Html… I hope the FF developers will be faster to solve this limitation in Html5

    Reading this post by David Bolter

    I understand that the problem is not to have focus on video, but to know it is there… I was wrong :)

    “Once a user has tabbed to a video, it is difficult to tell that the video has focus and there is nothing indicating that the video is keyboard controllable”

    I will do some test using Css to indicate active focus on video.

    I have updated my post about Html5 accessibility with this clarification and a link to Bolter’s article
