The document discusses the prototype stage in the design thinking process, specifically focusing on low-fidelity and high-fidelity prototypes. Low-fidelity prototypes are quick and inexpensive but lack realism, while high-fidelity prototypes provide more realism but require more time to produce. Various types of low-fidelity prototypes are also described, including sketches, paper interfaces, and role-playing techniques for user experience exploration.

2. The Prototype stage is when you create a
model designed to solve consumers'
problems or validate ideas that you can test
in the next stage of the process. It is stage 4
in the five-stage design thinking process.

4. Low Fidelity prototype
• Low-fidelity prototypes are
often paper-based and do not
allow user interactions.
• They range from a series of
hand-drawn mock-ups to
printouts.
• In theory, low-fidelity sketches
are quicker to create.

6. PROS AND CONS
OF LOW-FIDELITY PROTOTYPES

7. PROS OF LOW-FI PROTOTYPES
1.Quick and inexpensive.
2.Disposable/throw-away.

8. 3.Enables the designer to gain an overall view
of the product using minimal time and effort,
as opposed to focusing on the finer details over
the course of slow, in
Hmm...
I get an idea of the
product

9. CONS OF LOW-FI
PROTOTYPES
1. An inherent lack of
realism.
2. Users might have a hard time giving
feedback
3. Can oversimplify complex
issues
4. Lack of interactivity deprives users of
direct control.
5. Users must imagine how they would use
the product.

10. • High-fidelity prototypes are
computer-based, and usually
allow realistic user interactions.
• High-fidelity prototypes take you
as close as possible to a true
representation of the user
interface.

prototype
This is exactly
what I needed.
Let's test this
and implement
it. Yayyyy!

14. By seeing this prototype,
I get a clear vision of
how the end product
would be

15. Cons of hi-fi
prototypes
1 .They generally take much longer to
produce than low-fi prototypes.

16. 2.After devoting hours and hours of time
producing an accurate model of how a
product will appear and behave, designers
are often loathed to make changes.
I don't like it.
Change it

17. 3 .Making changes to prototypes can take
a long time, thus delaying the entire
project in the process. However, low-fi
prototypes can usually be changed within
hours, if not minutes, for example when
sketching or paper prototyping methods
are utilised.
I don't
like it.
Change it
Sure

20. • Sketching requires minimal effort
and does not require any drawing
skills to do it.
• sketches are used to begin the
process of conceptualising and
building a new product.
• Sketches can be shared with
teammates for more ideas and
discussions
• They can be extremely helpful for
making decisions.

23. Even the messiest
scribbles can be
considered as sketches

26. • Storyboard is a way of telling stories
and guiding targeted customers
through a user experience.
• This type is used for early
prototyping.
• It is presented in a series of images or
sketches.
• It evokes new ideas through
collaboration with other designers.
• This helps a designer to understand
the user's world and think from their
perspective.

29. 4 . R O L E P L A Y I N G
• Roleplaying enables designers to explore
target situations within the system
physically.
• It is used in capturing and enacting the
user's experience of a product.
• The designers create props,use objects
and audio simulations to imitate the user
environment.

34. 6. Wizard of Oz prototypes
• Prototypes with faked functions are called Wizard of Oz prototypes.
It was named of the story in which the wizard creates a deceptive
appearance from behind a screen.
• This prototype allows us to mimic certain aspects of your product
to save time and resources.
• It is a digital system prototype where the user is tricked into
believing that the system responses are computer generated when
they are human controlled.

38. • A user-driven prototype does not
test on users but allows the user's
to create some design, so you learn
more about thinking.
• Its purpose is to use their designs
to gain empathy with them or fine
tune your product according to
their ideas.
