Hi,<br>
It concerns me a little that this discussion seems to be all about
technology, rather than people and users. Low vision comes in many forms
and presents in many different ways. The best way to find out about low
vision is to talk to people with low vision. We will describe what works
and why. Real world testing with real people in real situations is
effective. Tools may be useful but are no substitute for connecting with
users.&nbsp; <br>
Cheers<br>

Can you use this software on the iPad with a web page. A colleague
of<br>
mine has often used this with a camera to demonstrate the visually<br>
impaired experience to people, but I am not sure if you can use it<br>
with the phone's browser to simulate the web browsing experience.<br>
If so, could you recommend a particularly good website to demo with<br>
this software, ideally something like the BAD (before and after<br>
demonstration) website with the same page in an inaccessible<br>
font/color and then with fixes applied.<br>
Thanks<br>

I believe VisionSim only works with camera mode; in other words, I use
it<br>
on my iPhone to take a photo and see the results of that simulated
low<br>
vision disability.&nbsp; However, I will keep looking for something
that<br>
operates like VisCheck (
<a href="http://www.vischeck.com/vischeck/" eudora="autourl">
http://www.vischeck.com/vischeck/<;/a> ) where it takes<br>
a URL and displays the results that way.<br><br>

The app relies on the camera in the iPad so you won't be able to use it
for a web page unless you have it pointed at a monitor.<br>
However, once you are viewing the image on the camera, you can take a
picture of it.<br><br>
The app is also free.<br><br>
I have it on my iPhone.&nbsp; While my sight is such that I can't tell
any difference using the app, it does make for a great way to talk about
accessibility and disability.&nbsp; When you pick a filter, it explains
some of the aspects of that type of visual impairment.&nbsp; You can then
let someone use the app to look at things and then start talking about
accessible design and how people with various types of disabilities use
technology--especially since you can then turn on voiceover or show them
the accessibility settings.<br><br>
I think the app makes a great way to start a conversation.&nbsp; And you
definitely know your audience is hooked once they start asking questions
about things they are looking at or making comments--&quot;The colours
seem a bit washed out.&quot; Or &quot;that is harder to read.&quot;&nbsp;

Message: 4<br><br>
That's what I thought as well.<br><br>
However it appears that the same behavior is being linked to role=dialog
as well, even though they are different widget types.<br><br>
This from the response at
<a href="http://www.nvda-project.org/ticket/2390" eudora="autourl">
http://www.nvda-project.org/ticket/2390<;/a><br><br>
&quot;It's not clear from the spec as to how description should be
handled for dialog, but it does refer to alertdialog as being related.
Also, dialogs do typically have a caption/description.&quot;<br><br>
If you would care to add your thoughts to the bug, I would appreciate
it.<br><br>

According to NVDA, widget control types such as role=dialog require not
just an aria-label or aria-labelledby attribute, but also an
aria-describedby attribute. I'm not able to locate where this exists in
the user agent spec however, at
<a href="http://www.w3.org/TR/wai-aria/roles" eudora="autourl">
http://www.w3.org/TR/wai-aria/roles<;/a></blockquote><br><br>
Perhaps you are thinking of alertdialog, not dialog?<br><br>
From #alertdialog
<a href="http://www.w3.org/TR/wai-aria/roles#alertdialog" eudora="autourl">
http://www.w3.org/TR/wai-aria/roles#alertdialog<;/a> : <br>
<blockquote type=cite class=cite cite="">&quot;Authors SHOULD use
aria-describedby on an alertdialog to point to the alert message element
in the dialog. If they do not, assistive technologies will resort to
their internal recovery mechanism to determine the contents of an alert
message.&quot;</blockquote><br>
In plain English, this means that if the author doesn't explicitly define
what the alert message is, the AT can and should do the best job it can
to tell the user to what it *thinks* is the alert message.<br><br>
There is no requirement for an aria-describedby relationship on dialog.
There is an author &quot;SHOULD&quot; requirement for a label, but not a
description.<br>
<a href="http://www.w3.org/TR/wai-aria/roles#dialog" eudora="autourl">
http://www.w3.org/TR/wai-aria/roles#dialog<;/a><br><br>
In both cases, the author &quot;SHOULD&quot; requirement would generate a
warning, not an error, so AT should account for dialogs without labels or
descriptions as well.<br><br>
