Re: Review this week: Media Accessibility User Requirements

Here are my comments so far.  I thought I should get this in so others
could have tome to read.

.. From Low Vision:
Text: "A person using a low-vision AT aid, such as a screen magnifier…"
Change: [A person will likely use a screen magnification to perceive
the non-text content.  This means that…]

Text: "They may have difficulty reading when text is too small, has
poor background contrast, or when outline or other fancy font types or
effects are used. "
Change: [They may have difficulty reading when text is too small, has
poor background contrast [(too low or high)], or when outline[d] or
other fancy font types or effects are used. [If the font is an image
then grainy blur is an issue]
…  ADD TO THE END:
[Users with low vision will need access to print streams made and any
hidden instructions available to users screen readers / refreshable
Braille. ]

Note 1: This last comment should probably be appended for atypical
color perception.
Note 2: A common misconception is that people with low vision don't
need the directions for blind users.  For aesthetic reasons authors
hide these from vision and people with partial sight miss them.
Note 3: Text that is delivered for use by screen readers will be
capable of having it's typography adjusted to size, color, spacing,
font and text decoration requirements of the user with partial sight
or atypical color perception. So, it will be much more accessible than
text that is embedded in the media.

.. Cognitive / Learning ..
Finally, autism is addressed so explicitly.  Great work! I could not
see how they cope with hyper visual people on the autism  spectrum
(picture thinkers).   Many struggle with words.  I once had an
autistic student who quit my database class because I used too many
words.
.. DV1-14
Very nice!  I had difficulty visualizing [audioize?] some of the
items, from an EO perspective examples / samples are needed.
.. TVD
This requires more than screen reader and Braille access.  LV can use
this too to augment audio
.. EVD
Extended Video Description is very useful for low vision.  I often buy
the scripts of movies with subtitles whenever available.  For a video
that requires more than one viewing this would really help.
Note: All text sent out should have a rich format open format like HTML.
.. Navigation
Well thought out.  I like it, but would have to use it.
.. Captions Stuff is out of my range of experience…
.. Transcripts Appear to be available for LV.
I always fear when terms like “available to AT” the author only means
screen readers, synchronized Braille or screen magnifiers.  Visual
semantics are needed for low vision
…
.. Granularity
Looks good, but should be reviewed for completeness before final draft.
