"Paper prototyping is a variation
of usability testing where representative users perform realistic
tasks by interacting with a paper version of the interface
that is manipulated by a person ‘playing computer,’
who doesn’t explain how the interface is intended to
work." – Paper Prototyping
The "Computer" highlights the
item the user has just selected. A member of the development
team observes and takes notes. The facilitator (not visible)
is sitting to the right of the user. (Photo courtesy of Timo

What kinds of interfaces can you prototype?
Paper prototyping can be used for virtually any type of human-computer
interface – software, Web site, hand-held device, or
even hardware. Its purpose is to get quick feedback from users
while the design is still (literally) "on the drawing
board." Some paper prototypes are hand-drawn, while others
use printed-out screen shots. |

How is paper prototyping related to usability testing?
The above definition of paper prototyping overlaps with usability
testing, but the two concepts are not quite the same. It’s
possible to conduct usability tests on real interfaces, not
just paper prototypes. And paper prototypes can be used for
purposes other than usability testing – some product
teams find them helpful in generating design ideas and conducting
internal interface reviews. |

What skills do you need? You do not need
to be a graphic artist or software engineer to create a paper
prototype, though those skills might come in handy when you’re
ready to build the real thing. If you have ideas for your
interface and can draw them – rough sketches will do
– then you can create a paper prototype. |
