Media Accessibility Requirements - comments

Accessible media requirements by type of disability

It's not a good idea to juxtapose "cognitive problems" vs. "vision disability"... consider the following edits:

The principle disabilities that affect the comprehension of media are loss of visual function and loss of audio function, sometimes in combination.<remove> To a certain extent cognitive problems also come into play, but this generally better addressed in the production of the material itself, rather than on providing access mechanisms to the content, although some access mechanisms may come into play for this audience. </remove> <add>Cognitive disabilities are also affected, but they are better addressed in the production of the content itself rather than through specific access mechanisms to the content, although some access mechanisms may come into play for this audience. </add> Once richer forms of media, such as virtual reality, become more commonplace, tactile issues may also come into play. Control of the media player is of course also an important issue e.g. for mobility problems, however this is typically not addressed by the media formats themselves, but is a requirement on the technology used to build the player.

 

Blindness

The first mention of Assisitive Technology in the document is as an acronym (AT). Suggest it be spelled out with the acronym in brackets after it.

...these ATs need to work hand-in-hand with the access.

Should be:

...these assistive technologies (ATs)...

Add to the end of the blindness paragraph.

People who are blind cannot use a mouse, and require all tasks to be keyboard accessible.

Low Vision

No need to spell out assisitive technology here:

A person using a low vision assistive technology aid, such as a screen enlarger, will only be viewing a portion of the screen,

Could be:

A person using low vision AT, such as a screen enlarger, will only be viewing a portion of the screen <add>at any given moment</add>,

Dexterity / Mobility impairment

Should not list blind as a dexterity/mobility imparment

People with dexterity/mobility (<remove>blind</remove>, physically impaired, tremors, etc.) issues ...

Awkward sentence "accessible access"....consider the following edits:

... The player itself <add>and it's controls</add>must be usable via the keyboard and pointing devices <add>, including accessible methods for selecting alternative content.</add> <remove> The user must have full accessible access to all player controls, including methods for selecting alternative content. </remove>
