What is a prototype?

!10

pro-to-type n.

1. An original type, form, or instance serving as a basis or standard for later stages.

2. 2. An original, full-scale, and usually working model of a new product or new version of an existing product. 3. An early, typical example

Service prototype

• The aim is verifying what happens when some external factors interfere during the service delivery, factors that it’s not possible to verify during the preceding tests in the laboratory but that have a great impact on the user perception and experience.

!15

The service prototype is a tool for

testing the service by observing the interaction of the user with a

prototype of the service put in the place, situation and condition

where the service will actually exist.

Experience Prototyping

• The experience prototype allows designers to show and test the solution through an active participation of the users.

What about the experience?

Keeping Connected Design Challenge Develop: Core activity sheet

Experience prototypingWhat is experience prototyping?

Experience prototyping is a method for testing new service ideas and designs. They are used to show what the experience will be like and help to test and develop parts of the solution.

Prototypes could be a physical model of a VSHFL¿F�WRXFKSRLQW��D�VNHWFK�RI�D�VLJQ�RU�D roleplay to focus on the service’s interactions. Prototypes should focus on the service’s most important or unusual touchpoints.

Prototypes do not need to look beautiful or take a long time to make. It is more important to create something quickly, test it and then improve the design.

Useful tips

Don’t be afraid to use your imagination; prototypes don’t need to work, they are just props to help explain what the experience might be like. Remember that prototypes are only created to help you improve, so don’t worry if it doesn’t VHHP�WR�ZRUN�¿UVW�WLPH�URXQG�

1 Look at your service blueprint and think

about which touchpoints might need protoyping.

2 Decide how you are going to prototype it;

you could make a model or act out an interaction.

3 Take photographs or video so that you can

review the prototype. Does the prototype meet the service principles you created in the discover stage? If not, how can you change it to meet them?

4 Ask your users to feedback on the

prototype. Remember to get the opinion of older adults and younger people.

5 Create another version of the

prototype with the improvements based on your users’ feedback...

• The experience prototype allows designers to show and test the solution through an active participation of the users. !

! it is NOT about the creation of a formalized toolkit or a set of techniques

!! it is about developing

an attitude and language to solve design problems


!19

The experience prototype

is a simulation of the service experience that foresees some of its

performances through the use of the specific physical touch-

points involved.

The story

I was a frequent pedal paddler when I was a kid until I got myself into an accident. After that I have never really found the two wheeled form of transportation to be quite as exciting again. Well, of course, I have been up in the saddle after that, and even gotten myself one of those high end mountain bikes when I was in my twenties, but I didn’t really use it that much. When it got stolen, I never cared to really venture into that territory again. Of course, like every guy, I have been pushed by adrenaline to get myself a motorcycle, but the thought of ending up in one of those accidents again, this time during way higher speeds, makes me want to take the safe route around. However, there are definitely other things out there that have wheels, and that are strikingly similar to biking.

What’s the contextual in it?

• Schilit and Theimer (1994) refer to context as location, identities of nearby people and objects, and changes to those objects.

• In a similar definition, Brown, Bovey et al. (1997) define context as location, identities of the people around the user, the time of day, season, temperature, etc.

• Ryan, Pascoe et al. (1998) define context as the user’s location, environment, identity and time.

• Dey and Abowd’s definition (2001) ! Context is any information that can be used to characterize the

situation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves.

CIF Tutorial Putting hands on Contextual Experience Prototyping

• The CIF Tutorial shall provide the participants with insights about

! targeting experiences when prototyping

! the role of context !

! usage of tools for contextual experience prototyping by example of the Contextual Interaction Framework

• controlling and measuring the environment

• studying experiences • supporting the researcher

!63

2


The Contextual Interaction Framework

!64

2


Motivation

• Conduct user studies in the (simulated) target context ! Analyze the interplay of user interaction and selected

context parameters ! Change selected context parameters and adapt

interactive systems (following the ubiquitous computing approach) to evaluate changes in user behavior !

• Rapid prototyping ! Speed up the development and configuration of interactive systems

and the simulated context in which they are applied. ! Reusing existing software components

!65

2


OSGi – Open Services Gateway initiative

• Multiplatform (based on Java) • Modularization using OSGi (Open Services Gateway initiative)

! Dynamic Module System: • Enables configuration at runtime via bundles (plugin-like concept): load

and unload, start and stop

! Exchange data between modules via services that provide predefined data types !

! Configuration of the data flow using the wiring concept

!66

2


What can the Contextual Interaction Framework do for us?

• Connect ! measurement devices (sensors) ! interaction devices (e.g. Wii, Kinekt) ! actuators (e.g. switches, audio)

!• Provide a framework to dynamically

! link the data measured or sensed to functionality (e.g. logging of button presses, calculate activity level of a user)

! Set states of actuators based on manual switches or other sensor data (e.g. switch a fan on if the user opens a window in a virtual reality simulation)

! Compute and calculate states and data based on user activities • Provide us with an integrated environment for conducting contextual UX studies

• Starting point: A pong game !

• Context: ! A pong game ! Playing pong with another person ! alternative interaction modalities

and alternative devices !

• Experience: ! Haptic experiences (sliding vs.

touching vs. pressure vs. …) ! Social experiences ! Body-based experiences ! …

Prototyping in the real world context

• Starting point !

!86

What experience do we want to design for?

Which context is relevant for us when designing an experience prototype?

2



• Starting point ! Interaction is usually done in one location. ! Performing dislocated interaction implies a number of experiences

based on the type, medium, feedback involved ! Experiencing colloborative interaction !

! Experiences done while interacting dislocated, ad-hoc, in a real-world context come up with unpredictable implications !

! The context of interaction is defined by • The availability of a controller • Intuitiveness and feedback • the perception of the human

with respect to his experiences

!87

2



• The prototyping experience … !

! Using mobile devices • Phones, Tablets • Ambient displays !

! Sensors and actuators • Accellerometer • Light • Vibra • Location services • Display • …

!88

Prototyping the ambient …

• Android Motion Controller • CIF

! Ambient Color Visualisation & Motion ! Communication

• Multiple devices ! cooperate & conquer

• Visual experience • Emotion - fun, mood, vibes, …

Prototyping the ambient …

• Discussion: !

! What is the Experience Prototyping here? ! What is different? ! The context? ! Did we experience a different prototyping experience? ! Did we reflect such in the prototype?

Lessons learned

• Focusing on experiences when prototyping is the key issue to a good UX !

• Thinking about the experiences I want to create with a prototype effects the design process !

• Tools like the Contextual Interaction Framework allow to quickly and dynamically create real-world prototypes that regard !

! (user) experiences ! in a specific context ! using particular contextual information !

• It is not about designing for the user but creating experiences for the audience …
