A few years from now, people new to the Internet will find it impossible to imagine an era before video online. What use is that content though, if your user is visually impaired? How do we go about indexing and searching it?

A few weeks ago IBM announced an “Accessibility Internet Browser for Multimedia” over at alphaWorks. It addresses the short-comings of JAWS or voice-enabled browsers, and is built on top to of the Eclipse Rich Client Platform as a stand-alone application. It means the play/pause buttons (normally unavailable to visually impaired users) are stripped out and made accessible, and that playback doesn’t ‘clash’ with voice-synthesised browser operation.

Developers can add metadata to reorganise or simplify the content, provide additional information, add special navigation or even provide audio descriptions for movies using XML metadata.

It’s this last point that I think is going to be interesting. If this tool - or one like it - becomes standard, and video producers are encouraged to mark-up their content properly, existing search and relationship algorithms can be applied to video content. Right now searching video content is pretty limited - maybe by making it accessible, we all benefit.
