Experience is a dynamic, complex, and subjective
phenomenon. It depends upon the perception of
multiple sensory qualities of a design, interpreted
through filters relating to contextual factors.
  Buchenau & Fulton Suri (2000)

Buchenau, M., & Suri, J. F. (2000, August). Experience prototyping. In Proceedings of the
3rd conference on Designing interactive systems: processes, practices, methods, and
techniques (pp. 424-433). ACM.

The experience of even simple artifacts does not
exist in a vacuum but, rather, in dynamic relationship
with other people, places and objects.
Additionally, the quality of people’s experience
changes over time as it is influenced by variations
in these multiple contextual factors.

“Experience Prototype is any kind of representation,
in any medium, that is designed to understand,
explore or communicate what it might be like to
engage with the product, space or system we are
designing.”
Buchenau and Suri

Design Evolution
  User-Centered Design (1980’s)
  Focus on thing being designed
  Ensure it meets user needs
  Participatory Design (1990’s)
  User part of the design process
  Roles of designer, researcher, user blur together
  Experience Design (2000’s)
  Design user’s experience of things, events, places

What I hear I forget. What
I see, I remember. What I
do, I understand!

Why Experience Prototyping?
More and more we find ourselves designing
complex and dynamic interactions with converging
hardware and software, spaces, and services.
The designer needs to focus on ”exploring by
doing" and actively experiencing the subtle
differences between various design solutions.

Why is it Important?
  Need to think about context of artifact use
  Where, why, what of object use
  Focus on “exploring by doing”
  Enables creation of common vision
  Important for multidisciplinary team
  Users can have informative personal experience
  Allows engagement with problems in new ways

Designing Human Activities,
not just Tools

Where it is Valuable
  Understanding existing user experiences and
context
  Simulating an existing experience
  Exploring and evaluating design ideas
  Testing prototyping in use context
  Communicating ideas to an audience
  Demonstrating to client in use context

Understanding User Experience
  Goal: To demonstrate context and identify issues
and design opportunities
  Through direct experience of systems
  Key questions:
  What are the contextual, physical, temporal, sensory,
social and cognitive factors we must consider?
  What is the essence of the existing user experience?
  What are the essential factors our design should
preserve?

Example: Heart Attack Monitoring
  Questions
  What is it like to be a defibrillating
pacemaker patient?
  Not knowing when and where
attack might come
  Solution
  Page people simulating heart attack
  Have users write down current
context

AgeSuit
  Create experience of what
it’s like to be elderly person

Exploring and Evaluating Ideas
  Goals:
  Facilitating the exploration of possible solutions
  Directing the design team towards a more
informed development of the user experience
  Experience already focused around particular
artifacts, elements or functions
  Testing existing prototype
  Evaluate with users, designers, clients

Example: New Aircraft Interior
  Re-create aircraft
interior design
  Simulate flight

Wizard-of-Oz Prototyping
•  The user thinks they are interacting with a computer, but a developer is responding
to output rather than the system.
•  Usually done early in design to understand users’ expectations

>Do this
>Why?
User

Communicating Ideas
  Allow client/users/designers to understand
design by directly experiencing it
  Goal of persuading audience
  Compelling, functional, visionary
  Especially important for new technology types
  Digital camera, wearable computer, etc

Examples
Apple Digital Camera Kiss Communicator

Contribution
  Experience prototyping contributes to
product design in three ways:
  Understanding existing experience
  Simulating important aspects of experience
  Exploration and evaluation of ideas
  Providing confirmation or rejection of ideas
  Communication of issues and ideas
  Allowing others to engage with new experience
