What do professionals do in the ID business?

• interaction designers people involved in the
  design of all the interactive aspects of a
  product
• usability engineers people who focus on
  evaluating products, using usability methods and
  principles
• information architects people who come up with

  products
• user experience designers (UX) people who do
  all the above but who may also carry out field
  studies to inform the design of products
• web designers people who develop and create the
  visual design of websites, such as layouts
• mangler der noget?

  the age of the consumer, designing human-centered
  products and services
• Alan CooperFrom research and product to
  goal-related design

• Develop usable products (usability)
• easy to learn
• effective to use
• provide an enjoyable experience
• Involve users in the design process (middel, ikke
  mål)
• Usability (ISO 9241)
• effect nytte
• efficient effektivt
• satisfying tilfredsstillende

Working in multidisciplinary teams

• Many people from different backgrounds involved
• Different perspectives and ways of seeing and
  talking about things

Usability goals

• Effective to use
• Efficient to use
• Safe to use
• Have good utility
• Easy to learn
• Easy to remember how to use

15
Activity on usability

• How long should it take and how long does it
  actually take to
• Using a DVD to play a movie?
• Use a DVD to pre-record two programs
• Goals acheived and tasks completed correctly and
  within time

16
The User Experience

• How a product behaves and is used by people in
  the real world
• "the way people feel about it and their pleasure
  and satisfaction when using it, looking at it,
  holding it, and opening or closing it"
• every product that is used by someone has a user
  experience newspapers, ketchup bottles,
  reclining armchairs, cardigan sweaters.
  (Garrett, 2003)
• Cannot design a user experience, only design for
  a user experience

17
User experience - nyt?

• Ultimately, usability lives in user experience.
  Therefore usability engineering must be grounded
  in user experience. Usability engineering
  provides tools for uncovering user experience.

Design principles

• Generalizable abstractions for thinking about
  different aspects of design
• The dos and donts of interaction design
• What to provide and what not to provide at the
  interface
• Derived from a mix of theory-based knowledge,
  experience and common-sense
• Examples
• Visibility
• Feedback
• Constraints
• Consistency
• Affordances

Löwgren Kritik af Preece (1. udgave)

• Preece (2002) Sharp (2007)Interaction Design -
  Beyond Human-Computer Interaction
• Löwgren (2002) How far beyond human-computer
  interaction is interaction design?
• HCI good at eliminating obvious problems for the
  users .... Interaction Design is a Design
  Discipline - innovation
• Design is not fixing little problems, but
  designing things that are both innovative and
  that work
• Sharp "ID is ... supporting people ..." games
  supporting people ??HCI-perspective of
  goal-driven users ... complete tasks
• Call Shift in epistemological foundation and
  professional practice
• Very capable presentation of contemporary HCI
  ..... does not go beyond HCI. It is not a book
  about interaction design.

Buxton som mellemmand

• Bill Buxton Sketching User Experiences - getting
  the design right and the right design.
• "This book is about design. ... There may be
  something concrete that you can touch, see, and
  hear. But there is also something that you can
  actively experience something that involves
  dynamics or time something with behavior that is
  usually the result of software running on an
  embedded microprocessor and something whose
  design needs to be grounded in the nature of that
  experience". (9)

25
Buxton som mellemmand

• "The underlying premise of the book is that there
  are techniques and processes whereby we can put
  experience front and centre in design. My belief
  is that the basis for doing so lies in extending
  the traditional practice of sketching" (9)
• "By virtue of their embedded microprocessors ...
  these products are going to be even more
  difficult to get right than those we have
  produced (often too unsuccessfully) in the past."
  (9)

26
Buxton som mellemmand

• "However, today's reality is that in this
  equation, the value of design is too often being
  questioned, and the contributions of the designer
  are being seen as an expensive luxury. Similarly,
  in software products, we are seeing the notion of
  user interface design disappearing as a
  professional description, too often being
  replaced by usability engineering, something that
  is ever more remote from something an industrial
  designer, would recognize as design" (12)
• "This book is based on the premise that design is
  a distinct discipline" (12)
• "A second premise is that although design is
  essential, it is not sufficient" (12)
