FYI - from NCAM - the demos work ok, except that since I'm not an expert screen reader user my speech rate is set much lower than the timing assumptions built into the video pauses in the demo. This causes audio overlap between the video and my screen reader. This is potentially something that could be built in personal preferences.

Apologies for the cross-posts.

Not long ago the National Center for Accessible Media at WGBH (NCAM) announced the availability of some demonstrations how the Popcorn.js HTML5 Media Framework can be used to deliver screen-reader accessible supplemental materials alongside video embedded in a Web page.  Our two prototypes-- http://ncamftp.wgbh.org/rd/hgp/ (which demonstrates accessible text and images alongside video) and http://ncamftp.wgbh.org/rd/quadratic/ (which demonstrates an approach to accessible math)-- have recently been updated.  On both sites, please read the instructions and system requirements, then watch the videos to see (and hear) accessible Wikipedia entries, glossaries, images with long descriptions and math displayed as the video progresses along its timeline. These demonstrations were made possible with funding provided by the Reader's Digest Partners for Sight Foundation.

After viewing the demonstrations, please take a minute to complete a brief survey by following the link found on each demonstration page.

Thanks very much.
Geoff Freed
