Title: Viewed from first person POV (user is 'inside' ... Viewe


1
Building Visualizations for Training Programs
  • Steven Schafrik
  • Virginia Center for Coal and Energy Research

2
Approaches to Learning
  • Visual
  • Auditory
  • Olfactory
  • Tactile or kinesthetic
  • The best learning occurs with multiple approaches

3
Development and Application of Visualization
Techniques
  • Multimedia Methods
  • Immersive/Non-Immersive Environments
  • Mockups

4
Multimedia
  • A multimedia system is a computer-controlled
    integrated production, manipulation,
    presentation, storage and communication of
    information which is encoded on a continuous
    (time-dependent) and/or a discrete
    (time-independent) medium.

5
Multimedia Features
  • Efficient Can replace information that is read
    with information that is seen and heard
  • Direct The ideal delivery method for
    information can be utilized
  • Interactive Genuine and multilevel user
    interaction

6
Multimedia Contents
  • Continuous (time-dependent) medium
  • Sound
  • Audio
  • Video
  • Animation
  • Discrete (time-independent) medium
  • Text
  • Graphics

7
Multimedia Components
  • A PC
  • CD-ROM or digital distribution
  • Sound card and speakers or headphones
  • GUI based Operating System
  • Multimedia creation/viewing software

8
The PC
  • Bare minimums
  • Pentium II
  • Sound Card
  • 10 Gigs of hard drive space
  • Low cost high power system
  • P4 (1.7 GHz)
  • GeForce4 video card
  • 40 Gigs of hard drive space

9
Multimedia Creation/Viewing Software
  • Macromedia Products (www.macromedia.com)
  • Director (PC based distribution)
  • Flash (Web based distribution)
  • Shockwave (Web based viewer)
  • Dreamweaver (Web design)
  • Emblaze Creator (www.emblaze.com)
  • Mobile multimedia devices

10
Immersive/Non-Immersive Environments
  • Virtual Reality Animations and Renderings
  • Non-Immersive Virtual Environment
  • Immersive Environment
  • Distributed Immersive/Non-Immersive Environments

11
Virtual Reality Animations and Renderings
  • Three-dimensional
  • Synthetic, computer-generated
  • Real-time graphics
  • Viewed from first person POV (user is inside)

12
Virtual Reality Animations and Renderings (cond)
  • Output from the renderings can be used stand
    alone or with a multimedia system
  • Ability to do forensic analysis
  • Produced using 3D Modeling software
  • 3D Studio (www.discreet.com)
  • Bryce (www.corel.com)
  • Maya (www.aliaswavefront.com)

13
Non-Immersive Virtual Environment
  • Three-dimensional
  • Synthetic, computer-generated
  • Real-time graphics
  • User interaction
  • Viewed from first person POV

14
Immersive Environments
  • Immersion
  • Known as presence
  • Sense of being there
  • Produced by
  • Enveloping environment
  • Natural interaction (view, manipulate)
  • Realism
  • Responsiveness

15
Immersive Environments (cond)
16
Distributed Immersive/Non-Immersive Environments
  • Networked Virtual EnvironmentsSoftware system
    in which multiple users interact with each other
    in real-time around the world
  • Collaborative Virtual EnvironmentsMulti-user
    computer-based systems which support
    geographically dispersed users

17
Mockups
  • Combination of physical simulation and virtual
    reality
  • High accuracy and
  • interaction
  • Expensive and
  • difficult to produce

18
Conclusions
  • This technology will be improving and continuing
    into the future
  • Web distributed forensic analysis is possible
  • Ideal technology for beginner training
  • H S training can be coupled with operational
    training
  • Train and simulate difficult situations or
    conditions
  • Web applications allow training to take place
    anytime anywhere
