No previous message | Next message →

Hi,

Are there any programs that can simulate a web browsing experience for
people with visual disabilities (not complete blindness)? I want to make
sure that the audience at my organization really gets why using HTML text
instead of images of text is important. I've told them things like, "When
you zoom in on a page a lot, images of text can get really blurry and
difficult to read." But I think some of them have tried doing that and
declared that they still seem pretty easy to read even at fairly high
magnification. But of course, they have excellent vision.

Here's the kind of thing that I would love to do:

1. Open a browser and go to a web page that has examples of both images
of text and HTML text.
2. Turn on a program that simulates low vision. All of the text will be
difficult/impossible to read at this point.
3. Zoom in on the page a lot in order to try to be able to read it
better.
4. At this point, the user should be able to see that magnifying the
page is helping with the HTML text, but not helping at all with the images
of text.

Another great one to do:

1. Open a browser and go to a web page that has both images of text and
HTML text.
2. Turn on a program that simulates a user that needs very high contrast
settings. All of the text will be difficult/impossible to read at this
point.
3. Change the computer setting to a high contrast mode.
4. At this point, the user should be able to see that the HTML text is
now readable, but the images of text did not change at all when the
contrast settings were changed.

Anything like that out there?

Thanks,
David Ashleydale

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

Birkir:

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

Thanks,
Elle

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.
However, once you are viewing the image on the camera, you can take a picture of it.

The app is also free.

I have it on my iPhone. 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. When you pick a filter, it explains some of the aspects of that type of visual impairment. 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.

I think the app makes a great way to start a conversation. And you definitely know your audience is hooked once they start asking questions about things they are looking at or making comments--"The colours seem a bit washed out." Or "that is harder to read."

Hi, 
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.  
Cheers

Robyn:

I completely agree that tools are never a substitute for real users (I was
compelled to write a blog post about this just last week). However, when
I'm in an internal meeting where decisions are being made that may put a
low vision user's optimal experience at risk, tools that are readily
available on my iPhone allow me to demonstrate what we're really discussing
in that moment. They provide an on-demand empathy that puts the user back
at the center of the discussion.

One day, my team will have low vision users on staff who can provide that
first-hand experience. One day, our usability testing with disabled users
will reinforce universal design principles with stakeholders. Until then,
however, these kinds of tools help provide a more concrete example than I
could with just my words.

Best,
Elle
