Question from last class?

Scenarios

“scenarios are stories”

John Carroll

They can have different formats

(text, video, story board)

They are used to create understanding within a group (negotiations in a working team)

To set the goals

To set the goals (future scenario)

To understand the use in time of certain object

To enrich dialogue with users

To show alternatives to clients

To motivate questions and imagination (what if questions)

To avoid enchantment with the first proposal

Elements in a scenario

Context- description of the situation in which the story takes place.

Actors-

Objectives- what is the goal of the actor involved?

Actions- what are actors doing?

Events- what happens to the actors?

Objects- what do the actors need to perform certain desired action?

5 reasons for a scenario-based design they are vivid descriptions of experiences from the user perspective

they propose one interpretation but they might present many alternative solutions

scearios can be written with different purposes or perspectives

scenarios focus the discussion in the work promoting discussion within the team

John Carroll (1999)

Scenarios are within the most powerful tools in the design of products and services

Kim Goodwin

A good scenario explain the reasons for the person for a certainbehaviour and the objectives that the person need to achieve.

Some people are against scenarios because they are invented. The scenarios are based in a human understanding of a particular type of

person. You know how a person will behave because you know what she loves. It is like buying a gift.

Kim Goodwin (2009)

Scenarios = User cases = User stories S the funtionality of the system is described in terms of what the user need to do. All the steps in the design.

UC funtional requirements. They focus on the user actions and the system behaviour. It is a complete catalogue of the task that the user do. They can have the form of a UML(unified modeling language) diagram.

US they are use in Agile programming in methods such as Scrum. They are requirements. Just one sentence. They do not describe the whole sequence from the beggining to the end. They do not focus in what the person things and feel.

Concept Design

They are used to represent an idea. It might be a vague idea about a system (a connected house), a suggestions for a service (remote control for the sauna from the telephone) a new use of an existing technology (voice interaction for tv remote control).

A concept can have different scenarios

Individual vs. organizational

Observation vs. visionary

All the process or just a phase

Background

software development processes

different stakeholders / different perspectivves

Emotions and reasons are part of the question. Example: uploading a picture of a new born baby

Scenarios are good when

What is wrong? The problem is not well-defined

What can we do? Possible movements are not explored

What can help? The objective is not clear

Scenarios are a concrete tool to evaluate and test concepts

Co-creation of future scenarios

Arki Research Group

Co-design- approapiation of new technolgies- community- building

To put it simple

Observe problematic scenarios1. Look what people is doing2. Pay attention to how they use other spaces/ objects/ services

Imagine scenarios

1. Better ways of doing what they do2. Better things to do3. Develop what you have imagine.

Critical Artifacts

It is one method used in Participatory Design

Critical Artifacs

are inspired in Critical Design

Simon Bowen

What is critical design?

Critcal design uses proposals to challenge preconceptions about the rol of the objects in evetyday life.

It is more an attitude or a posture than a method.

To name this critical design is a simple way to make more visible and object of discussion and debate.

Use design to pose questions

With humor

Sense of humorNot to shock but to provoke

To make it more humanTo tackle delicate issues

Why do we need critical design?

Basically for making us think. But also to make ideas conscious, expose preconceptions, motivate debate and even to entertain in

an intellectual way as the movies..

(Anthony Dunne & Fiona Raby 2007)

The conceptual design by Dunne & Raby are not done for selling and mass

production.

They are known through exhibitions

There is a lot of people doing critcal design but

they do not use this term to explain what they

If I would have asked people what do they want

they would have said a faster horse

Task for this class

Write a set of scenarios describing your concept.

Tips: Think how it can be created, shared and used.

Re-use actors to give it consistency.

Create a critical artifact

Task for next class

Read the following articles

Five reasons for Scenario-Based Design, by John Carroll. (2000). Interacting with computers- 43-60.

Critical Artifacts and participatory innovation by Simon Bowens. CHI 2010.

Do the exercise proposed in the paper you have read last class. Paper tittle: “Conceptual Designs”. Send the presentation to me on 24.10.2011

Or Finnish the scenario as a video scenario or as a polished storyboard. Think what can you do with it. .

Media Lab Helsinki and by Simon Bowens in a workhshop in Oslo, Nordes conference.
