| LIke any new technology, adoption
is driven by accessibility. This concerns developers and users
alike. Rich media players, being the interface between developers
and users are the center of accessiblity standards issues.
Rich Media Accessiibility
Rich media accessibility presents a number of challenges.
Whlist it can be developed with accessibility in mind and
the end product is used or viewed on accessible media players.
Accessing rich media captioning, audio description, and navigation
is generally done using a keyboard.
Media Player Accessibility
Media players must also be accessible to both users and
developers. This includes screen readers.
They must also provide authors with the means to add captions,
audio descriptions, extended audio descriptions, and subtitles.
Audio Descriptions
Current level of accessibility for media players varies greatly.
Some media players are accessible to developers, allowing
them to add video descriptions to be created and played, but
are inaccessible to screen readers. This means the audio descriptions
is not able to select the PLAY button.
Captions
Captions are not compatible between players. This means that
a caption created on one player, will look different when
played on another.
Whilst a number of media players are progressing rapidly
in improving accessibility of their products, we have a way
to go before full interoperability.
The best place to keep updted on accessible rich media is
the National Center
for Accessible Media Rich Media Accessibility. This site
provides a showcase of accessible rich media; tutorials on
captioning audio, descriptive video, making maps and other
forms of rich media accessible; strategies for dealing with
player and cross-platform issues; links to tools for rich
media authoring and viewing.
