What is Prototyping?
> Tangibility, experiencing and testing of results
> Prototypes allows end-users to participate early in the innovation process.
> Surface feel allows earliest understanding of complex challenges.
What kinds of interface can you prototype?
The Power of Prototyping
What is Paper Prototyping?
Why Paper Prototyping?
Built for your budget
Where does paper prototyping fit into
the design process?
1. The design team uses paper for their presentation to a larger group of people who have
a vested interest in the product.
2. Users run through a set of existing paper mock-ups or are given blank paper and asked
to represent a concept by sketching it.
Paper Prototyping Steps
1. Determine the key interactions
2. Sketch screen layouts:
3. Determine the screen ﬂow/sequencing:
4. Prepare interactive elements
5. Take your prototype for a test run
“Any design based on a written spec is
a design based on theory.
A design based on a prototype is
a design based on experience and practice.”

USABILITY TESTING WITH PAPER PROTOTYPES
> Allow users to mock up ideas they think would solve a problem.
> Mark on the prototype where a user attempted to “click” or otherwise interact with the interface
> Ask users to draw what they expect to happen next.
> Keep going even if you don’t have access to a testing lab or if computers, networks, or high-tech
prototypes don’t work as expected.
