  1. Virtual Environments: Applications Simon Julier, Anthony Steed Department of Computer Science University College London http://www.cs.ucl.ac.uk/teaching/VE

  2. Recall Role of Presence in VEs • Person observing the displays behaves as if the VE is “real” • When might this be appropriate for an application • When full engagement is necessary? • When want to train for real situations? • Want to convey complex information that benefits from a spatial layout? • Want to exploit human skills for exploring/understanding the ambient array of information surrounding them?

  3. Some Applications of VEs • Simulation and Training • Pyschological Treatment • Medical Diagnosis / Planning / Intervention • Design • Scientific / Information Visualisation • Entertainment

  4. Simulation and Training • Extremely high fidelity VEs • Particular types of vehicle simulator have been extremely successful • See Brooks’ paper web site “What’s Real About VR?” • Successful because the situation of use is limited and “near-field haptics” (i.e. the cab of the vehicle) is a physical copy! • Also one of the very few applications that often uses motion platforms

  5. Flight Simulator www.grc.nasa.gov/WWW/PAO/images/fullsize/flight.simulator.jpg

  6. CAE Airbus 380 Simulator

  7. Ship Bridge Simulator

  8. Battle simulation

  9. Psychological Treatment • Some types of phobias and stressful events are best treated through exposure therapy • Exposure to feared stimulus repeatedly and for prolonged period leads to habituation and extinction • Based on learning principles • Reliable findings • Therapeutic Exposure • Stimulus must be carefully controlled

  10. Treatment of Phobias Fear of Heights - GVU Centre, Georgia Institute of Technology Arachnophobia - EVL, University of Illinosis, Chicago

  11. Fear of Public Speaking COVEN (David-Paul Pertaub and others)

  12. Post Traumatic Stress Disorder (PTSD) Post-traumatic stress disorder: Virtual Vietnam from www.virtuallybetter.com

  13. Post Traumatic Stress Disorder

  14. Medical Diagnosis / Planning / Intervention • Modern medical sensing technology produces a plethora of data • Multi-modal • 3D • Time varying • Doctors and surgeons have to understand the spatial relationship of this data to use it effectively

  15. Virtual Colonoscopy

  16. Virtual Colonoscopy Non-invasive MRI used to generate model of colon; colon visualised using “catheter view” of data

  20. Design and Evaluation • Designing products can be extremely expensive • Multiple iterations must be built as physical mockups • Initial construction costs • Time waiting for the mockups to be built • Mockups cannot be fully functional • In aircraft, can’t necessarily have real, active controls • VEs offer a way to design, prototype and test what things will look like

  25. Complex Assembly, Maintenance and Repair http://aig.cs.man.ac.uk/gallery/divipro

  26. Scientific / Information Visualisation • Complicated data sets are becoming easier to come by • Accurate physical simulations of weather, measurements from distributed sensor networks, etc. • This data is often multi-dimensional and difficult to analyse • By turning the data into something tangible that is visualised, detection and discovery is enabled

  30. Oil and Gas Exploration • Networked Visualization in the Oil and Gas Industry http://www.sgi.com/features/2001/jun/statoil/

  31. Collaboration and Entertainment • The applications so far have mostly involved interaction with data • Visualisation of data / design / engineering • However, VE systems can be used to support collaboration between people as well • And, of course, VEs can be used for entertainment as well

  32. Telecollaboration: ‘Office of the Future’ • Camera based reconstruction of an environment and tracking of person UNC CH

  35. Improving User’s Experience at the Dentist

  36. Summary Some applications are possible with extremely cheap hardware • E.g. treatment of arachnophobia • As applications get more complex must trade off utility against the often onerous cost of engineering the system • The most expensive “VR” applications are probably flight simulators, but the simulator is still cheaper than flying the real thing
