Introduction to HCI
• Today’s agenda– Team 3: Hall of Fame / Hall of Shame– Why think about Design?– What is Design?– Where do ideas come from?
• brainstorming• the morphological box
Design
• Why design? • Two tracks: design project, design process
– Process and product get equal weight– Scenario-based design is just one method!
• Developing a content design vocabulary• Developing a process design vocabulary• Do, reflect, do
WHAT IS DESIGN?A survey of ideas about design and
designing.
Design is defined in terms of…
• Method• Product• Goal
The OED defines design as:
• A plan or scheme conceived in the mind and intended for subsequent execution; the preliminary conception of an idea that is to be carried into affect by action; a project.
• To mark out; to designate; to name.• To sketch.
Design is problem solving.
[cognitive science]
Design occurs in the tension between what is and what ought
to be.
“Form follows function.”
[Louis Sullivan]
“Design is a mode of action.”
[Charles Eames]
Design is an act of individual heroic creation.
[Howard Roarke in Ayn Rand’s The Fountainhead]
Design is form-giving.
[translation of “design” from Norwegian]
Design is a social activity.

Design is just one of
the four creative
disciplines
Design is making something new that fits with reality.
[Harrison & Stults]
“Good designers copy; great designers steal.”
[Steve Jobs, after Pablo Picasso]
To design is to manipulate representations of an imagined
future reality.
Design is the science of the imaginary.
[Herbert Simon]
Design is the art of the imaginary.
Design is the engineering of the imaginary.
Imagination and Representations
• The mind sees what the ear hears
Imagination and Representations
• The ear hears what the eye sees.
Most invention is design.
Some design is invention.
Design is appearance.
Good design increases sales; great design creates market
leaders.[Raymond Lowey]
Values collide when people design; good design reflects good
values.
[Batya Friedman]
“God is in the details.”
[Ludwig Mies van der Rohe]
Design is evocative.
Design is a reflective practice.
[Donald Schon]
Design is optimization.
[engineering]
Design research is pattern-finding; designing is pattern-
applying.[Christopher Alexander]
Iterate.
Debug this into reality.
[hackers’ creed]
Design process: Enumerate aspects of solution space,
evaluate each one.
[Zwicky, Whittle, Card]
Design addresses wicked problems. [Horst Rittle]
• Wicked problems have no definitive formulation, but every formulation corresponds to a formulation of a solution.

true or false, only good or bad.

• Wicked problems have no stopping rules.• Solutions to wicked problems cannot be
true or false, only good or bad.• There is no exhaustive list of admissible
operations to finding a solution.
Design addresses wicked problems. [Horst Rittle]
• For every wicked problem there is always more than one possible explanation.

• For every wicked problem there is always more than one possible explanation.
• Every wicked problem is a symptom of another higher level problem.

• The problem solvers (designers) are fully responsible for their actions.

Each Definition Implies a…
• Different relationship of designer to:– user– client– customer
• Different way of measuring the outcome• Different way of thinking about use
WHERE DO IDEAS COME FROM?
The first of many methods for and reflections on design ideation.
Brainstorming Morphological Box
Brainstorming
Developed in response to “group think” Basic rules:
Someone keeps list so everyone can see No idea is too wild No evaluation Silence does not mean “DONE”
Fun and “light weight”
