Re: Powerpoint Video Accessibility

Hi,
I think your only hope is having those linked from something like
YouTube or a bundled HTML page.

Some some of our PowerPoints have longdescs that have structure (like
tables as longdescs for charts/graphs), we've considered recommending
some slide decks just come bundled with an HTML page for these (then a
chart/graph/whatever can use a real hyperlink to this bundled HTML
file). Same goes for the video players. You could have the inaccessible
one still on the slides for students/instructors who want to play from
there, but the Real Thing will be an accessible HTML5 player in a
bundled HTML page.

Another benefit of an HTML file is users can access everything a browser
can offer. Users of for example Dragon can choose to open this file in
IE for getting the most control of the video player, while a screen
reader user who likes NVDA can choose to open it in Firefox.

This is what we've been doing in Product. We certainly haven't found a
way to make the video players within the PPTs accessible-- PowerPoint is
just too limited in its own capabilities :(

cheers,
Mallory
