    • Design
      David Lamas, TLU, 2011
      3
    • Design
      From google
      Noun
      A plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made
      Verb
      Decide upon the look and functioning of (a building, garment, or other object), typically by making a detailed drawing of it
      David Lamas, TLU, 2011
    • Design
      Design is a creative activity whose aim is to establish the mufti-faceted qualities of
      Objects
      Processes
      Services, and their
      Systems in whole life cycles
      Design is also…
      the central factor of innovative humanization of technologies; and
      the crucial factor of cultural and economic exchange
      David Lamas, TLU, 2011
      5
    • Design
      The rational model states that
      Designers attempt to optimize a design candidate for known constraints and objectives
      The design process is plan-driven
      The design process is understood in terms of a discrete sequence of stages
      David Lamas, TLU, 2011
      6
    • Design
      The action-centered model
      Designers use creativity and emotion to generate design candidates
      The design process is improvised
      No universal sequence of stages is apparent
      Analysis, design and implementation are contemporary and inextricably linked
      David Lamas, TLU, 2011
      7
    • Interaction design
      David Lamas, TLU, 2011
      8
    • Interaction design
      According to Allan Cooper…
      Interaction design is the practice of designing interactive digital products, environments, systems, and services
      Further, interaction design is heavily focused on satisfying the needs and desires of the people who will use the product
      It is, however, about behavior and not so much focused on form or appearance
      And behavior is much harder to observe and understand than appearance
      David Lamas, TLU, 2011
      9
    • Interaction design
      Dan Saffer identifies three ways of looking at interaction design
      These are views centered in
      Technology
      Behavior
      Society
      David Lamas, TLU, 2011
      10
    • The technology centered view
      Interaction designers make technology, particularly digital technology, useful and pleasurable to use
      This is why the rise of software and the Internet was also de rise of the field if interaction design
      Interaction designers take the raw stuff produced by engineers and programmers and mold it into products that people enjoy using
      David Lamas, TLU, 2011
      11
    • The behaviorist view
      According to Jodi Forlizzi and Robert Reimann…
      Interaction design is about defining the behavior of artifacts, environments and systems
      This view obviously focus on functionality and feedback being concerned on how products behave and provide feedback based on what the people engaged with them are doing
      David Lamas, TLU, 2011
      12
    • The social interaction view
      Interaction design is inherently social, revolving around facilitating communication between humans through products
      Technology is nearly irrelevant in this view
      Any kind of object or device can make a connection between people and these connections can take many forms
      They can be one-to-one, as with a telephone call
      They can be one-to many, as with a blog
      They can be many-to-many, as in the stock market
      David Lamas, TLU, 2011
      13
    • Interaction design
      Although these are distinct conceptualizations of what interaction design is, the common ground is that…
      …they all perceive interaction design as an applied art that solves specific problems, under a particular set of circumstances, using the available materials
      However, generalizations have been made and true rules have emerged that defy the applied art claim
      David Lamas, TLU, 2011
      14
    • Interaction design
      Common to all conceptualizations of interaction design are the four approaches to address it
      User centered design
      Activity centered design
      Systems design
      Genius design
      All have been used to create successful products
      And it is typically up designers to select the approach that better addresses the problem at hand
      David Lamas, TLU, 2011
      15
    • Interaction design
      David Lamas, TLU, 2011
      16
    • Interaction design
      Again, common assertions apply
      These approaches can be used in many different situations to create distinct products and services
      Most problematic situations can be improved by deploying at least one of these approaches
      The best designers are those who can move between approaches, applying the best approach to the problem at hand
      An individual designer will probably gravitate toward one specific approach in detriment of others
      Designers will generally work with the approaches they feel most comfortable however, some other approach might be the best way to address a given problem so interaction designers should know all four
      David Lamas, TLU, 2011
      17
    • Experience design
      David Lamas, TLU, 2011
    • Experience design
      But what is this experience or user experience?
      Different people understand it in very different ways
      A group of user experience experts has been working on a white paper, which is an important step towards a common understanding of the concept of user experience however, a number a distinct definitions still coexist, which indicate that this is not yet a mature concept
      David Lamas, TLU, 2011
      19
      Available in our shared dropbox
    • But what is this experience or user experience?
      The term user experience is often used as a synonym for…
      usability
      user interface
      interaction experience
      interaction design
      customer experience
      web site appeal
      emotion
      wow effect
      general experience
      …or as an umbrella term incorporating all or many of these concepts
      David Lamas, TLU, 2011
      20
    • Experience design
      Some definitions…
      All the aspects of how people use an interactive product: the way it feels in their hands, how well they understand how it works, how they feel about it while they’re using it, how well it serves their purposes, and how well it fits into the entire context in which they are using it.
      http://delivery.acm.org/10.1145/240000/235010/p11-alben.pdf?key1=235010&key2=2405233021&coll=GUIDE&dl=GUIDE&CFID=16757653&CFTOKEN=13134697
      David Lamas, TLU, 2011
      21
    • Experience design
      Some definitions…
      All aspects of the end-user’s interaction with the company, its services, and its products. The first requirement for an exemplary user experience is to meet the exact needs of the customer, without fuss or bother. Next comes simplicity and elegance that produce products that are a joy to own, a joy to use. True user experience goes far beyond giving customers what they say they want, or providing checklist features. In order to achieve high-quality user experience in a company’s offerings there must be a seamless merging of the services of multiple disciplines, including engineering, marketing, graphical and industrial design, and interface design.

      David Lamas, TLU, 2011
      22
    • Experience design
      Some definitions…
      A consequence of a user’s internal state (predispositions, expectations, needs, motivation, mood, etc.), the characteristics of the designed system (e.g. complexity, purpose, usability, functionality, etc.) and the context (or the environment) within which the interaction occurs (e.g. organisational/social setting, meaningfulness of the activity, voluntariness of use, etc.)
      http://www.uni-landau.de/hassenzahl/pdfs/hassenzahl_LR_91-98.pdf
      David Lamas, TLU, 2011
      23
    • Experience design
      So, how can we address experience design?
      Marc Hassenzahldistinguishes three different levels, when designing an experience through the interaction with an object…
      The Why level
      The What level; and
      The How level
      Marc Hassenzhal is also one the co-authors of the definition of user experience presented in the previous slide
      David Lamas, TLU, 2011
      24
    • The why level
      David Lamas, TLU, 2011
      25
    • The what level
      The What addresses the things people can do through an interactive product, such as…
      making a telephone call
      buying a book
      listening to a song
      It is reflected by a products' functionality
      The What is often intimately tied to the technology itself or a certain product genre.
      David Lamas, TLU, 2011
      26
    • The how level
      The How level addresses acting through an object on an operational, sensory-motor level
      Buttons pressed
      Knobs turned
      Menus navigated
      Touch screens stroked
      Remotes waggled
      The How is tied to the actual object to be designed and its context of use
      It is the typical realm of the interaction designer…
      to make given functionality accessible in an aesthetically pleasing way.
      David Lamas, TLU, 2011
      27
    • (back to) The why level
      The Why aims to clarify the needs and emotions involved in an activity, the meaning, the experience
      Only then, it determines…
      the functionality that is able to provide the experience (the What); and
      an appropriate way of putting the functionality to action (the How)
      David Lamas, TLU, 2011
      28
    • From the Why to the What and the How
      David Lamas, TLU, 2011

    • Design strategy
      David Lamas, TLU, 2011
    • Design strategy
      Design strategy is the product and project planning that takes place at the beginning of a design process
      It is a combination of…
      defining a vision for the end state of a project, and
      determining the tactics needed to execute that vision
      It is composed of:
      Framing the problem (or opportunity) to be addressed
      Determining key differentiators for the product to be design
      Visualizing and selling the strategy to the organization
      Creating a product roadmap and a project plan to achieve its goals
      David Lamas, TLU, 2011
      31
    • Design strategy
      Although design strategies are usually driven by business strategies
      The reverse can also happen
      After the success of the iPod, Apple Computer became just Apple when as it realized that its future was also in consumer electronics
      David Lamas, TLU, 2011
      32
    • Design strategy
      As it happens with design in general, a design strategy is usually achieve through a series of divergent and convergent steps, involving…
      Research
      Observations
      Analysis
      And also…
      Ideation
      Principles
      Refinement
      David Lamas, TLU, 2011
      33

    • Design strategy
      But what is it exactly?
      Instead of letting a wish like “let’s design this new widget” drive
      a design process, making a design strategy explicit, allows questions like…
      What should we be designing hat will meet our organization’s needs and the needs of our customers?
      How should that solution be manifest? As a widget or something else?
      …determine how the design process should be driven
      David Lamas, TLU, 2011
      34
    • Common development lifecycles
      David Lamas, TLU, 2011
    • Common development lifecycles
      A development lifecycle is a project management framework
      Current development lifecycles are the result of accumulated experience and best practices but should not, nevertheless, be dogmatically adopted
      Although not sole relevant project management frameworks, these two approaches are the predominant development lifecycles
      System development lifecycle, and
      Agile lifecycle
      David Lamas, TLU, 2011
      36
    • System development lifecycle
      This is a framework used to describe the process for building information systems
      It is intended to develop information systems in a very
      deliberate
      Structured, and
      methodical way
      David Lamas, TLU, 2011
      37
    • System development lifecycle

      http://www.justice.gov/jmd/irm/lifecycle/ch1.htm
    • Agile development
      Agile development is based on an iterative and incremental approach
      Requirements and solutions evolve throughout the project by means of collaboration between self-organizing, cross-functional teams
      David Lamas, TLU, 2011

    • Methods and techniques
      David Lamas, TLU, 2011
    • Methods and techniques
      To finalize, we will just go over some of methods and techniques used when designing for new media
      These include…
      Personas
      Scenarios
      Card sorting
      Prototyping
      Paper prototyping, wireframe prototyping, etc…
      And many others…
      David Lamas, TLU, 2011
      44
    • Personas
      A personais an artifact that consists of a narrative relating to a desired user or customer's daily behavior patterns…
      using specific details, not generalities
      David Lamas, TLU, 2011
