Building Visualizations for Training Programs Steven Schafrik Virginia Center for Coal and Energy Research
Approaches to Learning • Visual • Auditory • Olfactory • Tactile or kinesthetic The best learning occurs with multiple approaches
Development and Application of Visualization Techniques • Multimedia Methods • Immersive/Non-Immersive Environments • Mockups
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.
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
Multimedia Contents • Continuous (time-dependent) medium • Sound • Audio • Video • Animation • Discrete (time-independent) medium • Text • Graphics
Multimedia Components • A PC • CD-ROM or digital distribution • Sound card and speakers or headphones • GUI based Operating System • Multimedia creation/viewing software
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
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
Immersive/Non-Immersive Environments • Virtual Reality Animations and Renderings • Non-Immersive Virtual Environment • Immersive Environment • Distributed Immersive/Non-Immersive Environments
Virtual Reality Animations and Renderings • Three-dimensional • Synthetic, computer-generated • Real-time graphics • Viewed from first person POV (user is “inside”)
Virtual Reality Animations and Renderings (con’d) • 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)
Non-Immersive Virtual Environment • Three-dimensional • Synthetic, computer-generated • Real-time graphics • User interaction • Viewed from first person POV
Immersive Environments • Immersion • Known as presence • Sense of “being there” • Produced by: • Enveloping environment • Natural interaction (view, manipulate) • Realism • Responsiveness
Distributed Immersive/Non-Immersive Environments • Networked Virtual Environments:Software 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
Mockups • Combination of physical simulation and virtual reality • High accuracy and interaction • Expensive and difficult to produce
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
