Why?● Simply put … because you can.● There is very little “should” here● Looking back at John Maeda’s Laws of
Simplicity – Always question the addition of anything,
even if it leads to the reduction of something else.
Let’s look deeper at some good reasons why.

Hello! Humans are Emotional
Don Norman’s Emotional Design
Your emotional state when using a product will effect not just your enjoyment of it, but your effectiveness (at least perceptual) with it.
“Attractive Things Work Better” is the very title of the first chapter.

Intuitive ?● Creating an intuitive application is all
about matching expectations of the user.
● Understanding the context of use is the best way to come as close as possible to do that.
● The desktop is a constant. The Operating System is the heart and soul of the desktop experience.

Legacy of the Web ?● Strong legacy with web metaphors
– Back button (or just “history”)– Hyperlink

Learnability● Understanding where I was and where
I’m going.● Having the RIGHT information at the
right time, with the right supporting information.

Security● Using windowing enhances security
– I know that I really didn’t leave– I know when I’m done I’ll be going back to
where I started
● Security allows for more risk taking

Managing Complexity
Discoverability● Use scent to guide people● Hide complexity to avoid overwhelming
people with too much content● Richness allows for fluidity and better
invitations

Power of Movement● Sometimes contrasts in color, shape,
alignment are not enough● Moving objects catch our eyes and our
mind’s attention
● Time is perception– Motion (and change) = activity– Perception of system working if not faster,
at least working for my benefit.

What is “design”?● Design as noun (I like that “design”)
– Is the result of a conceived idea, whether or not it was actually “designed”
● Design as verb (I “design” software)– A process of creativity– Non-linear– Assumes there is more than one elegant
solution to any single problem– Considers the measurable and the aesthetic

Making Design (verb) Work
● Divergent thinking– Skew, bend, melt, tear … change!
● Evaluation is separate from Ideation– Put your judge on hold
● Multiple minds
● Model, Model, Model (AKA: sketch, sketch, sketch)
● Taking the road least traveled can bring you back to the freeway– Process ideas in disconnected ways
– Connect disconnected ideas in separate exercise

Exercise: Moving forward● Need to share corporate media objects
across different enterprises● Need to collaborate on these objects
– Annotate– Version– Append
● Need to publish out to 3rd parties
Don’t worry we aren’t doing this whole application …

Exercise: AnnotateDesign a set of screens that make up
one page
1. Displays both a list objects and single object
2. Allows the user to comment on that object
3. Track commenting
4. Annotate on media directly
5. Create a collection and “send” that collection

Things to think about● Manage complexity through progressive
presentation● Motion aids learnability● Prirotize information and tasks within a
single context● “Do I need a new context?” “Why?”
“Why not?”● “What is the nature of my data for this
context?”
