-: Within this lecture, I want to talk about alternative text
and reading order.
Let's say I've prepared this presentation.
This is box number one, two, three.
Obviously, this is how I want it to be read.
I'm going to review, I'm going to check accessibility
and here in the accessibility we have reading order pane.
I can see the reading order is improper.
I should take group number three and put it at last.
Why is that important?
It's very important if someone uses a screen reader
I have enabled a screen reader for myself.
Let's preview this presentation
-: Slideshow, slide four.
One, a pictogram is a chart that uses pictures
to represent data.
Three, two basic ways to use pictograms.
Two, pictograms can make your data more memorable.
Accessibility .pptx PowerPoint, slide four, slide view.
-: Did you see the problem?
If your reading order isn't properly set up
the screen reader will read it in a wrong order.
The same goes for alternative text.
When someone, for example, gets your presentation.
Here is a picture.
If I select edit old text, there is no alternative text.
But on the second picture, I've enabled some text.
I wrote it myself.
One wing of a plane on a blue sky.
Now look at that.
If someone accesses this presentation
and clicks on this picture
-: Graphic
-: He only knows that it's a graphic.
But if you give it alternative text
-: Graphic, one wing of a plane on a blue sky.
-: The screen reader will actually know what that is,
will read the context of this graphic.
It's important that both you get your reading order in order
and your alternative text for things that need
alternative texts.
You can also enable alternative texts for basically any box.
For example, if the person would edit this-
-: Grouping, the first box explains what a pictogram is
-: Okay. He would now know
that the first box is about this and that topic.
Because I right-click it,
I selected edit all texts
and I explained it in the alternative text.
If it's only a decoration, if it's only a box to decorate
you can mark it as decorative.
If you mark it as decorative,
this screen reader will simply go forward
avoiding this shape here.
