Introduction
  • Both wanted to
  • Wanted to do something different.
  • Use Multimedia approaches
  • Media and research challenges
  • Policy World a dynamic multifaceted environment
    where context and time are key elements.
  • Within the Matrix capture experience more
    wholistically

Retrospective Sensemaking
  • Why?
  • Can one create a VR-based policy visualization?
  • Use information technology to teach policy
  • What can a policy visualization reveal?
  • Context, complexity, and dynamics
  • Role of time in policymaking
  • Importance of policy history learning
  • Inadequacy of a popular policy framework

Pixelating Policy A Metaphor
Pixelating Policy is a metaphorical reference
to a digital imaging technique, in which a
portion of a digital image is progressively
magnified until the individual pixels (or picture
elements), the basic elements of a digital image,
can be seen. Policy World uses the basic
elements of graphics graphic primitives to
represent the basic elements of public policy.
This research examined the basic elements of
public policy to understand how issues are
transformed over time.
6
Project Scope
  • Research Question How were the paperwork
    concerns of 1975 transformed into the
    e-government concerns of 2002?
  • Theory Questions
  • Do issues transform? If so, . . .
  • Can issue transformation be identified? If so, .
    . .
  • Is there a relationship between issue
    transformation and policy change? If so, . . .
  • What is that relationship?

7
Research Approach
  • Case study Federal IRM policies from 1975 2002
  • Primary Sources Congressional hearings on IRM
    issues
  • Issues Were relevant before 1975 are still
    relevant
  • Paperwork Reduction
  • Privacy
  • IT Acquisition
  • Management Reform
  • Records and Information
  • Computer Security
  • Content Analysis Witness testimony coded to
    identify values, issue definition(s), and
    affiliation

Creating a Web Space
  • What possibilities could a web space
  • uniquely offer to the representation of
  • scholarly writing and qualitative
  • research?
  • What would you have to take into
  • consideration in creating such a
  • space?

11
Creating a Webbed Space
  • Assumptions
  • Hermeneutics of Web Writing
  • Criteria for Evaluation
  • File Organization
  • Navigation
  • Orientation and Indexing
  • The Collective

12
Navigation
  • Menu Levels
  • Icons
  • Image Maps

13
Navigation
  • Menu Levels
  • Icons
  • Image Maps

14
Orientation Indexing
  • Orientation
  • Image Maps
  • Information Box
  • Index

15
Evaluation Criteria
  • Hermeneutic Phenomenology
  • Content
  • Interactive Structure
  • Interface Design
  • Hyper-linking
  • Multimedia

16
Hermeneutic Phenomenology
  • Turning to the phenomenon.
  • Investigating experience as we live it.
  • Reflecting on the essential themes.
  • Describing the phenomenon through
  • writing and rewriting.
  • Orientated pedagogical relation.
  • Balancing parts and whole. (van Manen, 1995)

17
Content
  • The content is accurately represented in the
    combination of text, multimedia, and hypertext.

18
Interactive Structure
  • Reader is free to chart alternative courses
    through the word mass I fabricate
  • (Taylor Saarinen, 1994, p. 13).
  • The path choice is clear for the user.
  • The interactive structure is used to pace
  • the reader.

19
Interface Design
  • Visually coherent.
  • Textual visual elements blend.
  • The work is riddled with gaps, spaces and
    openings that invite the reader to write (Taylor
    Saarinen).
  • Navigational conventions are easy to
    understand.
  • Reader has a sense of location.
  • Navigational system supports overall work.
  • Each screen follows basic graphic design
    principles.

20
Hyper-linking
  • Links within the text are well placed and
    connected.
  • Text is presented in the first four levels in
    manageable chunks and linked to other chunks.

21
Multimedia
  • Text is expressed as media through the use of
    font, placement, and size.
  • Media is used to express ideas better than in
    words.
  • Supports and adds to the understanding of the
    theme.
  • Thoughtfully used to enhance a particular theme.
  • Used to add novelty to representation of the
    content.

Comparisons and Contributions
  • Part III
  • Role of Time
  • Context
  • Perspective
  • Creative Process
  • Contributions

26
Time
  • Dwight
  • Time is the primary constant in policy activities
  • Time helps structure dynamic and complex
    activities
  • Time, rather than policy frameworks, is linear
  • All policy activity is time-dependent
  • Paulette
  • Capture immediacy in experience
  • Deconstruct time to spatial rather than
    sequential (navigation)
  • Context of screen time
  • Pausing and pacing time through animation

27
Context
  • Dwight
  • Policy World visualizes the policy context
  • In representing complexity, policy theory, policy
    issues, and policy change are simultaneously and
    visually deconstructed
  • Context is represented by using graphic
    primitives, color, and movement
  • Paulette
  • Spatial/holographic
  • Shapes as representative (lines, circles,
    squares)
  • Images as containers for meaning
  • Navigation

28
Perspective
  • Dwight
  • Perspective is provided by point of view (POV)
  • POV can be altered by the viewer while
    constructing meaning
  • POV can be from an internal or an external
    perspective
  • Paulette
  • Reader chooses preferences of perspective
  • Reader created the experience every time
  • If it had been possible, the reader becomes the
    writer

29
Creative Process
  • Dwight
  • No previous models
  • What is represented?
  • Theory
  • Evidence
  • Possibilities
  • How do you bring content into a virtual world?
  • Visuals
  • Auxiliary html pages
  • Representation
  • Paulette
  • Ah-hah moment
  • Drudging through the system
  • Making the image real
  • Iterative

30
Contributions
  • Dwight
  • First policy oriented VR world
  • Visualized context and dynamics of policy and
    institutional process
  • Discovery-based learning approach to public
    policy, IRM, and eGovernment
  • Paulette
  • Creating a multifaceted experience through
    representing it in graphicsweb hermeneutic
  • Spatial design/navigation
  • First of its kind
