[NFBCS] A Web Access Curiosity

[Curtis Chong]

Steve:

I am assuming that on the computer that did not experience the problem, the
Zoom factor was set at 100% and not 175%?

This situation has indeed revealed an interesting (and for some perhaps
vexing) puzzle. How is it that the Zoom setting in a browser affects what
the screen reading program presents to the blind user? My intuition would
never have made this assumption<smile>.

Cordially,

Curtis Chong

Subject: [NFBCS] A Web Access Curiosity

With all of the things that prevent us from easily accessing websites, I am
sometimes amazed at the new things I encounter.  I'm wondering if anybody
here has thoughts on the following problem even though I've found a
solution.

I have two different computers that I use to enter my time for my employer.
My employer still asks that we use Internet Explorer so that is the browser
I am using for this.  Without having us go off on a tangent, I've used
Chrome on this website and it works, but frankly, it actually does not work
as well as Internet Explorer.  That isn't relevant here, though.

Here is the issue.  One of my computers works fine.  However, when I use the
other computer, some links and text near the top of the page do not appear.
The entire remainder of the page is exactly the same as it is on the
computer that works.  I am normally using JAWS, but I tried both Narrator
and NVDA on this page and all three give the same results.  It doesn't seem
to matter which cursor I use or scan mode or anything, the first three or
four links and some associated text just don't seem to be there at all on
one computer.  

I started checking settings, and I found that the Zoom level was set to 175%
on the computer missing text and links.  I don't know how that would have
happened since I do not use my computer visually, but so be it.  While I
realize that a zoom level would cause less of the page to appear on the
computers display, I didn't think that would affect what is in the virtual
buffer, but I set the Zoom level to 100% just in case.  All of a sudden, the
missing links and text appeared and both computers acted the same way on
this particular web page.  My problem has been solved, and clearly I will
now remember to check the zoom level.  However, I am left wondering what
other parameters may affect what is displayed that can explain why some
people can use a site without a problem while others have difficulty?  Since
I do not believe that what appears on the screen likely affects the virtual
buffers used by screen readers, I am thinking the website is displaying
differently based upon what settings it finds.  I know that there are sites,
for example, that display differently on small screens.  Is it possible for
a website to know the zoom level and render differently taking that into
account, or is something else happening in this case?  At least screen
reader behavior seems to be consistent in this particular case.  

I wonder if there might be advantages to reducing the Zoom Level more to
make sure that as much is on the screen as possible.  Of course, it occurs
to me that putting too much on the screen might cause a website to not
display text labels that are helpful to us.  <smile>  Any thoughts on all of
this?  At the very least, this has implications for those having low vision
that use the Zoom Level to make text more visible.

Best regards,

Steve Jacobson
