Human Centered Design is a design process based on users perspective. There are some product designed by IDEO on the basis of HCD.

1. HUMAN CENTERED DESIGN
It’s a process that starts with the people you’re designing for and ends with
new solutions that are tailor made to suit their needs. Human-centered
design is all about building a deep empathy with the people you’re
designing for; generating tons of ideas; building a bunch of prototypes;
sharing what you’ve made with the people you’re designing for; and
eventually putting your innovative new solution out in the world.

2. • Phase 1: Observation
The first phase is all about observing the end-user, learning, and being open to
creative possibilities.
Your goal is to understand the people you’re designing for.
Identify patterns of behavior, pain points, and places where users have a difficult
time doing something—these all lend to tremendous opportunity. If you can, put
yourself in their situation so you can see what their experience is, and feel what
they feel.
• Phase 2: Ideation
In this phase you start brainstorming ideas with your team based on what you
learned from your observations and experiences in Phase 1.
Your goal is to come up with as many ideas as you can.
As you’re coming up with ideas, stay focused on the needs and desires of the
people you’re designing for. If you do this, your group’s ideas will eventually evolve
into the right solution.
• Phase 3: Rapid Prototyping
In this phase you’re going to quickly build a simple prototype of your idea. This
makes it tangible and gives you something to test with the end-user.
Don’t try to build a fancy high-fidelity prototype right now. IDEO is notorious for
creating simple prototypes made out of cardboard.
The purpose of this phase isn’t to create the perfect solution, it’s to make sure
your solution is on target.

3. • Phase 4: User Feedback
Get your simple prototype into the hands of the people you’re designing for.
This is the most critical phase of the human-centered design process. Without
input from your end-user you won’t know if your solution is on target or not, and
you won’t know how to evolve your design.
• Phase 5: Iteration
Once you get feedback from your users, use that information to fuel the changes
to your design.
Keep iterating, testing, and integrating user feedback until you’ve fine tuned your
solution. This may take a few rounds, but don’t get discouraged. With each
iteration you’ll learn something new.
Once you’ve gotten your solution to a point where it’s ready to be used, it’s time
to move on to the next and final phase.
• Phase 6: Implementation
Now that you’ve validated the usefulness of your solution with the end-user and
gotten your design just right, it’s time to get your idea out into the world.
If you’re designing software products, apps, or websites, go back to Phase 1 and
repeat this process. With each new update that you implement, continue to
observe your users, design for them, and use their feedback to direct your future
solutions.

4. SCHOOL DESK
The Node chair is mobile and flexible. It's
designed for quick, easy transitions from one
teaching mode to the next. With Node, a
classroom can transition from lecture mode to
team mode without interruption.
The Node chair is highly mobile, which
translates directly into classroom
performance. A lesson plan can be carried out
more effectively when seating is arranged and
rearranged effortlessly, taking the burden off
educators to adapt.
Characteristics
•Style: contemporary
•Material: metal, plastic
•Market: school
•Options: on casters, with armrests, tablet
•Base: star base

5. This sitting unit is based on a tripod caster
that gives it a high mobility.
Because of high mobility with out any
interruption ,It is easy to change one
teaching mode in another.
1. Presentation mode
2. Lecture mode
3. Team mode

6. TEFF SEED PLANTER
• Teff, the world's smallest grain indigenous to
Ethiopia, is difficult to plant. The traditional
broadcasting method overuses and crowds the
seeds. With an agro-scientific discovery that
row planting gains higher yield, the Ethiopian
Agricultural Transformation Agency (ATA) looks
to design a mechanism that improves yield.
• IDEO.org started developing a mechanism for
the ATA in 2012. In Spring 2015, IDEO Chicago
partnered with the Northwestern design team
to refine the planter for future manufacturing.

7. INSIGHTS
• Farmers are resourceful. - while
they lack modern mechanical
knowledge, they know local
workarounds.
• The design must balance best
agro-science with best usability. -
A scientifically precise planter will
not be adopted by the farmers if
it is too cumbersome to operate.
• In order for the planter to thrive
in rural Ethiopia, it must
be affordable, lightweight, simple
and robust.
THE PLANTER
• The human-powered planter
dispenses teff seed and
fertilizer, 4 rows at a time, with
the wheel rotation. The internal
metering unit maintains a
constant rate independent of the
farmer's walking speed.
• Key refinements and
prototypes in this phase include
wheels, row markers, seed
recovery valves, seed level
markers, compactors, and animal-
powered adaptation.

8. Carafe-inspired Kettle
• Inspired by the unique heat-resistant
properties of BASF’s Ultrason polymer,
HEAT is a materials exploration
reinterpreting a kettle.
• The award-winning carafe-inspired
Kettle allows you to watch the water
as it boils in a clear, cool-to-the-touch
plastic vessel, which can be placed
directly on any surface after heating.
• A metal plate at the bottom of the
double-walled design heats the water
by induction, making the Kettle safer
and easier to clean.

9. INRatio2
• HemoSense, a maker of in vitro
diagnostic systems, wanted to make it
easier for patients to frequently check
up on their own well-being. The
company partnered with IDEO to
develop a self-testing monitor for
analyzing coagulation parameters
(prothrombin time [PT] reported as
the international normalized ratio
[INR]) at home. The team’s challenge
was to create an instrument that was
affordable, simple to use, and
provided fast, accurate results.

10. The INRatio2 is a handheld device that lets patients check
their own PT/INR levels in less than 1 minute, using a single
drop of blood from a finger prick. The straightforward, icon-
based interface guides them through the process on a large,
easy-to-read LCD screen: Insert a test strip (which
automatically turns on the monitor), put a drop of blood on
the strip, and in less than one minute the results are
displayed.

11. A TOILET FOR EVERY HOME
• For the millions of Ghanaians without in-home toilets,
there are few good options when it comes to our bodies’
most basic functions. Working with Unilever and Water and
Sanitation for the Urban Poor (WSUP), IDEO.org developed
Clean Team, a comprehensive sanitation system that
delivers and maintains toilets in the homes of subscribers.
• One of the main components of Clean Team is a custom-
designed stand-alone toilet, but what sets Clean Team
apart is the turnkey waste-removal system that supports it..
One of our biggest learning's was that though no matter
how compelling or aspirational the toilet itself, no one
wanted to slosh a bucket of waste through their homes.
Accordingly a full-on delivery, removal, and maintenance
system was born.
