Patterns & Elegance
Our Brain = Pattern Recognition Machine™

More Patterns = Less To Think About 



Less To Think About = Wheee! Sweet! Me Gusta!

Patterns can be complex…
…but too much complexity
can make them irritating
Grouping
Grouping
People can only hold a small number of
objects in their working memory.
Grouping
Research tells us the number is 3, which is
evidenced by many cultures counting: 



1, 2, (3,) Many
Grouping
We have to work around that with grouping
(which ideally supports abstraction).
Grouping - Circle Count
count the circles 😬
Grouping - Circle Count
spatial grouping
Grouping - Circle Count
color coding

BOOM! Patterns!

HAH!

Even contrast and spacingallow us to recognise

Typographical Contrast

Becomes important
when the text we
look at is small in
size (or far away)…
Typographical Contrast
Hello, I’m an iPhone.
I’m running iOS 7.
Bow before me!
…or problematic
when Apple
decides to be

Typography - Reading
Character shapes, grouping, contrast
(size, thickness, color) help our
pattern recognition
So!
Now that we know

Lets see if we can
