Subject: How does blind users access graphical information as charts (flowcharts, organisation chart)
No previous message | Next message →

Does anyone can guide me. I am new in this mailing list and have few questions and hope to find some answers with you.
How does blind user access graphical information like flow charts, organisation charts?
What are the most common methods and tools used?
Does it allow a blind user to have the same experience as sighted users?
What does a blind user think of the accessibility of this kind of graphics on the web?
Do they have some ideas of what they would like to see happen?
When accessing a flowchart or organisation chart, what kind of information are they interested in?
I have read a lot on accessibility but didn’t find much on graphics (charts) accessibility except providing text alternatives or long descriptions, but Is it enough to make charts accessible, some are very long to describe, is there anything else that exist?
What kind of information do I need to describe?
If I want to check that my complex chart is accessible to a blind person, what kind of method do I need to use?
Thanks
Lydia

One option to consider is to create your org chart or flow chart as
html rather than a graphic.

Here's one I built for our division a couple of years ago...

<http://www.sa.sdsu.edu/organization/index.html>;

It has a table for the basic structure, but uses a hierarchy of <h>
levels and linearizes pretty well I think. I'm convinced the same
thing could be done with a series of nested lists and CSS. (one of
these days. ;^)

Anyhow, depending on your specific organization or "flow", it might
be something to try.

HTH,

Keith

Hi Lydia,

These are very good questions. One of the best ways to get answers is to ask people who are blind! Here is a resource that can help you with that: "Just Ask: Integrating Accessibility Throughout Design". It talks about finding people with disabilities, including them in your project, and methods for evaluation.

"Just Ask" is available as a print book, and the entire thing is online free from:
www.uiAccess.com/JustAsk/

I hope you find it useful.

~Shawn

Hi Lydia,

You may also find the videos available at the following URL useful.

For more see the previous thread on Webaim:

for HTML5 WG

I think you will find the footage useful.

Lydia,
how would you describe that kind of information over the telephone?
Perhaps this perspective could give you some ideas about what works
and does not.

Good question! In Florida, we celebrate vision awareness month and our
kick off is for people who are blind to describe how they do their jobs
using technology. I forgot completely about scheduling some staff to
tell how they access this type of information.

Also, I believe you are talking about braille readers verses "blind" in
general. (I have friends who are blind who use large print or CCTVS to
access graphics.)

Here's a bit of information to get you started.

I work closely with four speech readers who require statewide data. Two
prefer getting hard data for charts or graphs using an excell spread
sheet and two want a description using word.

For maps and building layouts we still have requests for tactile maps.
We are blessed with a tactile embosser (makes graphics in tactitle
format) and people that know how to use it. This is not always the
case. But such can be made by organizations like American Printing
House.

Workflow layout, if made in something like Viseo, just needs to be
redone using alternative text. When org charts are made in an
electronic formate, even if accessible, we always get requests for
alternative descriptions.

Here is an article that can give you more info on tactitle layouts.

cumentID=3016

Hope this helped. Feel free to contact me at = EMAIL ADDRESS REMOVED =
if you would like to talk. About 20% of our staff has a visually
impairment. The four that work at the state office our managers and
must accesses data as part of their jobs. Use of tactitle charts is
often not a choice because of the turn around time, rather than user
preference. Deceisions often have to be made quickly.
