So this video is going to show a few examples
of how parallax scrolling can appear for someone
who's using a magnifier.
I’m using the built-in zoom on a Mac computer.
I’m going to pull up the browser here with
a few different websites.
So, there's three features I want to show
related to parallax scrolling and magnification.
The first is that the extra movement involved
in parallax scrolling can be confusing, disorienting
when the screen is magnified.
So, here’s a website, I believe it’s for
a French advertising agency.
I’m just going to scroll down the page.
There are different images and words and it
is really hard to tell what is going on, particularly
because things are coming in and out of view.
Is that a menu or not a menu?
I can’t tell and then it’s gone.
Okay, the next website example shows a different
aspect of how parallax scrolling can look
with magnification, which is that it’s hard
to sometimes establish visual landmarks which
are really helpful for magnifier users when
the parallax scrolling creates different layers
visually.
So, here I am on the page.
I see that there is a list of links here and
there’s a red bubble above it.
Okay, I’m going to scroll down the page,
but the bubble is also scrolling.
So typically, I would use that bubble to stay
oriented but the bubble is following me.
There’s a blue bubble. Let's see...
So, it’s more difficult to stay oriented
with fixed visual points.
The third website is an example of both of
these concepts I just showed.
First of all, there is movement in the background,
which can be a little confusing.
Am I moving the screen, or is the screen moving?
It’s also hard to establish a fixed visual
point.
Let’s see, there was text in this
corner and now it’s gone.
I’m not sure why it is gone.
And the third element I want to show here
is that when using parallax scrolling,
it can be easy to miss text or other content
not knowing where it goes or not knowing if
it even exists if it is displayed in an atypical
way.
So, this text can be scrolled which is a little
bit hard to follow, but I’ve understood
that it scrolls and whoops!
Where have I gone?
It scrolled to some new place,
and as I am scrolling, 
text is appearing and disappearing,
and I’m not sure where to look for text
on the page.
That is the end of parallax scrolling examples.
