The Anatomy of Sketching!
•  Quick / Timely!
•  Inexpensive / Disposable!
•  Plentiful!
•  Clear vocabulary. You know that it is a sketch
(lines extend through endpoints, …)!
•  No higher resolution than required to
communicate the intended purpose/concept!
•  Resolution doesn’t suggest a degree of
refinement of concept that exceeds actual state!
•  Ambiguous!

If you want to get
the most out of a
sketch, you need
to leave big
enough holes.
Sketching in Interaction Design!
•  Analogous to traditional sketching!
•  Shares all of the same key attributes!
•  More feel than look!
•  Must accommodate time & dynamics!
•  Phrasing!
There has to be
enough room for
the imagination.
Design as Choice!

Exploration of Alternatives!
Reduction
… a designer that pitched three ideas would probably be fired. I’d say 5
is an entry point for an early formal review (distilled from 100’s). … if you
are pushing one you will be found out, and also fired. … it is about open
mindedness, humility, discovery, and learning. If you aren’t authentically
dedicated to that approach you are just doing it wrong!

Exploration of Alternatives!
People on a design team must be as happy to be wrong as right. If their
ideas hold up under strong (but fair) criticism, then great, they can proceed
with confidence. If their ideas are rejected with good rationale, then they
have learned something.
…
There are no dumb questions. There are no ideas too crazy to consider. Get
it on the table, even if you are playing around. It may lead to something.

Experience vs. Interface Design!

a vacuum but, rather, in dynamic relationship with other
people, places, and objects” – Buchenau & Suri 2000

Minimal Detail!
Include only what is required to render
the intended purpose or concept!
•  Draw my phone!
•  Draw my phone’s interface!
•  Draw the experience of
using my phone!
•  Which is the true object of
design?!

Summary!

Next Time!
•  Sketching allows exploration of many
concepts in the very early stages of design!
•  As investment goes up, need to use more
and more formal criteria for evaluation!
