Re: How does blind users access graphical information ascharts (flowcharts, organisation chart)

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

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.

Hope this helped. Feel free to contact me at <EMAIL 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.

Subject: [WebAIM] How does blind users access graphical information
ascharts (flowcharts, organisation chart)

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
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?
