Human-Centered Design as a Mindset
Connecting Design Practice, Education, and
Research
Continuing with your design
Specification Development
Stakeholder Analysis
Observation and Interviewing
Conceptual: Brainstorming and Creativity
EPICS Design Process
Specification Development Phase: Goal is to understand “what” is needed
by understanding the context, stakeholders, requirements of the project, and
why current solutions don’t meet need, and to develop measurable criteria in
which design concepts can be evaluated.
Understand and describe context (current situation and environment)
Create stakeholder profiles
Create mock-ups and simple prototypes: quick, low-cost, multiple
cycles incorporating feedback
Develop a task analysis and define how users will interact with project
(user scenarios)
Compare to benchmark products (prior art)
Develop customer specifications and evaluation criteria; get project
partner approval
Gate 2: Continue if project partner and advisor agree that have identified
the “right” need, and if no existing commercial products meet design
specifications.

Cultural Lenses: Janus Face of Culture
Within a culture,
people are similar.
Positives
• Easy to learn and
remember images
• Allows us to use
patterned responses
tuned to images
Negatives
• Oversimplifies
• May blind us to
exceptions
• Sometimes difficult
to detect changing
dominant images
Even within a culture,
people are different.
Positives
• A much more
realistic outlook
• Encourages us to
focus on
individuals
rather than groups
Negatives
• Complexity can
be overwhelming
• Individual actions
difficult to interpret
• Optimal responses
not always clear

Stakeholder Analysis
From Dean Nieusma (2012), "Seeing Social Power: Technology Design for User Empowerment,"
http://globalhub.org/resources/5178
1.
For a project you are working on, characterize
the intended beneficiaries and how your
proposed technology is intended to meet their
needs.
Stakeholder Analysis
From Dean Nieusma (2012), "Seeing Social Power: Technology Design for User Empowerment,"
http://globalhub.org/resources/5178
2.
Identify as many distinct social categories within
the targeted beneficiary community as you can.
Consider:
• Age
• Sex/Gender
• Relevant income categories
• Racial/Ethnic/Familial Association
• Geography/physical location
• Level of education
• Ability/Disability
• …
Stakeholder Analysis
From Dean Nieusma (2012), "Seeing Social Power: Technology Design for User Empowerment,"

3.
Identify and characterize the various project
implementers—all groups external to the
beneficiaries that participate in design and
implement the project.

picture.
Exercise #2: Observation vs. Interpretation
Adapted from IDEO’s Human Centered Design Toolkit: http://www.ideo.com/work/humancentered-design-toolkit/
2.
Write down two interpretations of this
person’s behavior.
Develop an Interview Plan for Users*
* - that you may not be familiar with.
Adapted from IDEO’s Human Centered Design Toolkit: http://www.ideo.com/work/humancentered-design-toolkit/
1.
Start with “comfortable” knowledge (e.g.
what do you do for a living? where are
you from?
2.
Ask about bigger (relevant to the project)
questions. What are their dreams for the
future?
3.
Probe deep. Ask the highly relevant
questions related to your project.
Develop an Interview Plan for Project Partners
Used with permission from Prof. Megan Sapp Nelson.
1.
Ask “Who? What? When? Where? And How?”
questions:

2.
Keep an open attitude throughout the interview.
3.
Show attention by body language.
4.
Focus on content and ideas. Make mental notes of
questions to ask when the speaker is finished.
5.
Ask probing questions that will provide opportunity
for details to emerge.
Exercise #2: Observation vs. Interpretation

2.
List 3-5 questions to ask her to determine
which (if any) interpretation is correct.
EPICS Design Process
Expanding the Design Space
Brainstorming
Brainstorming can be done individually
or as a team
Team brainstorming = Taking
advantage of the contributions of the
team
Sum is greater than the individuals
Theory is to stimulate our brains to use
our whole brain to expand the options to
include the best solution
Brainstorming rules
Explain the entire procedure to the team
Choose one facilitator
Records ideas and participates in the generation
of ideas.
Record ideas that are easily visible to the whole
team.
Rotate around the group with each person
getting to add one idea per rotation.
Let members say “pass”
Move quickly.
NO value judgments. Write ALL ideas down
Facilitator treats ALL ideas the same
Continue until the entire team is passing
Brainstorming – 6-3-5
Group of 6 people
Each person writes down 3 ideas
Pass to right, next person adds to
paper for 5 minutes..
Ideas can be new, extend, or modify
original ideas
No verbal communication during
activity
Brainstorming – 6-3-5 Practice
Get in groups of 6; select one project
from your group
Each person writes down 3 ideas
Pass to right, next person adds to
paper for 5 minutes..
Ideas can be new, extend, or modify
original ideas
No verbal communication during
activity
Each group
How many different ideas did your
group come up with?
Did you start running out of new
ideas?
Triggers
Triggers are specific tools to actively bump your brain out of its ruts.
They are designed to get you thinking from a different perspective.
Many triggers are available (crazy, creative people are always
thinking up more), and some are listed below.
Other’s Shoes – Reconsider the problem from the perspective of a
plumber, civil engineer, physician, child, attorney, basketball player,
etc. You can keep this close to your personal comfort level by
picking roles you know something about, like plumber perhaps, and
then expand to more fanciful ones, like princess.
Nature – How does nature deal with this issue, or how would you do
it if you were Mother Nature?
Opposite – How would you solve the opposite problem (from “cut
down a tree” to “grow a tree”)? Or, consider the opposite of some of
your ideas (from “cut with a saw” to join with “hot glue”).
Random – Use random words, pictures, movie titles, professor
names to generate more ideas.
More Triggers
Analogy – Consider what has similar function but different
appearance (automatic clothes washer to washboard), what has
similar appearance but different function (washboard to cheese
grater), or what has a similar name and different use (bottle cap to
baseball cap)?
Craziest Idea – take the craziest idea and try use the kernel to get to
a practical solution (“Cut down a tree with scissors” to “cut with large
hydraulic shears”).
Boundaries/Constraints – Remove, adjust, or explore the
boundaries of the problem. (If the problem is a better way to wash
clothes, what about recycling the old shirt into a new shirt instead of
washing? Does it have to be “wash” or can it be “clean” or
“deodorize”?)
Anthropomorphize – Consider yourself to be the piece of equipment
or process. Or consider yourself a molecule flowing through the
system. (For “Why is this part failing?” think- “Am I getting hot
anywhere, where do I feel the stress?”)
Combine – Take different ideas and see what happens if you add
them together, or combine them in some other way (Problem: “wash
clothes” – combine “spray with a hose” and “pound on a rock” to
“spray with wet rocks”)
Other – Brainstorm your own trigger or find a trigger in a reference.
Brainstorming - SCAMPER
Substitute – can you use a different method, device, or
material or changed the environment?
Combine – can you combine ideas together to produce
a better idea?
Adapt – what ideas are similar that could be emulated
or adapted to fit the current need?
Modify, Minify, Magnify – can you change the current
idea, make it smaller or larger in some way?
Put to other uses – can you use the idea in a new way?
Eliminate – are there any ideas that have been shown
to not work?
Reverse, Rearrange – would an opposing idea give you
additional information, or can you interchange the key
elements of the idea to form a new one?

Prototypes
Prototyping….rough, quick, very iterative
IDEO working with Gyrus ACMI to design
new apparatus for operating
on delicate nasal tissues
Prototype: whiteboard
marker, 35 mm film
canister and clothespin
Mouse for Apple
Prototype: roller ball from
tube of Ban Roll-on deodorant to the base
of plastic butter dish

Characteristics of “beginning
designers”
Accept “problem” as given – surface level issues
Skip research – pose solutions immediately
Fixate on first ideas – disconnect from “problem”
Make premature design decisions
Few or confounded experiments
Unfocused way of troubleshooting
Unaware or unable to deal with complexities,
tradeoffs, competing issues
Design “haphazardly” or in a linear fashion (recipe)
Tacit designing with little self-reflection
(From Crismond)
Characteristics of “informed designers”
Recognize ambiguity and complexities – “explored the
challenge”
Do research on the problem, test assumptions
Practice idea fluency (problem evolves with design ideas)
Delay decisions until they explore the challenge
Use words, sketches, prototypes to explore ideas
Conduct valid experimental tests
Focus on key problems when troubleshooting
Consider benefits and trade-off when making decisions
Design in a managed way – strategic and iterative
Practice reflective thinking – learn THROUGH design

Experience
Results suggest that critical or immersive
experiences involving real clients and users were
important in allowing the students to experience
human-centered design in more comprehensive
ways.
All students in “Commitment” had critical
experience.
Sejal’s wake-up call
All students in “Empathic Design” had immersive
experiences
Rapid prototyping experience
Assessment trip to developing country
New Way of Thinking
Being introduced to human-centered
design concepts brought a new way of
thinking about design.
Andres: I think it was mostly having more
things to think about or introducing ideas and
ways of thinking about things that you wouldn’t
always think about normally or wouldn’t come
up with on your own.
Gina: I didn’t think in terms of user-centered
design when I came to college. You just think
an engineer designs things.
Context of Experience
Impact of academic context on experience of
design
Not focus of study, but requires further study
Initially surprised about the degree to which
students discussed aspects of the course.
For most students, design experience was very
much situated in academic context.
Most students described multiple
experiences from different contexts.
Area to explore is how the student perceived
various experiences and the impact of those
different perceptions on their learning.
Realness of design
Approached design differently because of context
