We can use background color to a certain extent
to say this block of information is related to this block but
if there was another chunk of text, maybe we want to
change not only the background color, we want to change the font style.
And, we want to make use of clear headings, so
we can say this heading and
then in another block say another heading and
maybe identify it as a subcomponent of the previous heading.
And this, I mean, the HTML is easy do it with heading tags, we can see this is
a level two heading, a main block of text and
this chunk is a level three heading meaning it's a sub-section.
So, there are many, many attributes that can be used,
programmatic structures, things that can be ascertained visually as
well as in those cases, when a text to speech application is employed.
>> And so again, we're reducing our information density, more bullets,
less text or maybe at least we're reducing our information clutter and
we're using redundant coding.
We can use color but also proximity, borders, labels,
all of these different things to help somebody make things as visually and
we're supported auditorily distinct and identifiable as possible.
>> Yeah, for example, moving away from the digital environment briefly, let's say,
you have a big tray full of nuts and
bolts and you need to find the bolt of a specific side and the nut to fit it.
Well, they're all just jumbled together, have fun, you're going to be there awhile.
But, if we have a nice tray that's sorted into compartments and
the compartments holding the quarter inch bowls and
the quarter inch nuts are both labeled quarter inch and they are both in blue,
it's going to be, you're going to get that job done a lot faster.
Same thing holds for the digital interface.
