Experience Prototyping
What is an Experience?
What Makes Up Snowboarding? Weather Terrain Snow conditions Air temperature Bindings and boots Board qualities Skill level Current state of mind, etc..
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.
Experience Prototyping 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.
Consider the Whole User
User Experience Factors
Experience Prototyping “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!
Lao Tse
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

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

‘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
>Blurb blurb >Do this >Why?
User
Example: Mobile Navigation
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
