  • WHAT IS VIRTUAL REALITY?• “Virtual Reality is a way for humans tovisualize, manipulate and interact withcomputers and extremely complex data.”• Virtual reality is often sometimes called asSynthetic Environment, Cyberspaces ArtificialReality, Simulators Technology, etc.
  • VIRTUAL REALITY: STEPS OFDEVELOPMENT1. HMD—helmets2. BOOM—BinocularOmni-Orientation Monitor3. CAVE—CAVE Automatic Virtual Environment4. 3D VIDEO Eyewear5. Input devise, Output Devise6. Hardware7. Software

  • Applications Entertainment– More vivid– Move exciting– More attractive5
  • Applications (Cont’d) MedicinePractice performing surgery.Perform surgery on a remote patient.Teach new skills in a safe, controlled environment.6
  • Applications (Cont’d) Manufacturing– Easy to modify– Low cost– High efficient7
  • Applications (Cont’d) Education & Training– Driving simulators.– Flight simulators.– Ship simulators.– Tank simulators.8
  • Early UsesLate 1960’s (the main playersin history)• U.S. military radar system& NASA• Ivan Sutherland’s“Sketchpad” for designers• Flight simulators• That cool headgear returns!
  • Current Uses• Virtual reality warzone stress reliever• VR treatment withkids• Movieentertainment• Video gameentertainment
  • • Training– Military• Microsoft flight sim?– Scholarly– Medical– Construction– Law Enforcement– Lots more….
  •  Interaction with the environment. User interface. user can see and even feel the shaped surface underhis/her fingertips. Flight simulators and games. CAD/CAE Biomedical Engineering the projects mentioned areuse of virtual reality for viewing of X-RAYs and MRI‘s. Rendering and 3-D lighting, modeling for resourcemanagement.
  • New technologies have also revealed new problems.VR in medical treatment is going through some growingpains.There are limitations with VR devices as well in regardsto usability.lack of standardization of hardware and protocolsMost troublesome are the side effects it can induce, likedisorientation, dizziness and nausea.People often find navigating in 3-D spaces andperforming actions in free space extremely difficult.practical problems in spatial cognition research
  • Future of VR?• Future only bound by technological advance– Nanotechnology?– Implants?• U. Washington already researching:– Retina image screening– Nervous system implanting (EEG and EMG)• Unmanned Flight– Gulf War…
  • Summary Visualization of complicated, large data is helpfulfor understanding and analysis. VR offers us a new way to interact withcomputer. VR enables us to experience the virtual worldthat is impossible in real world. VR is changing our life, eventually VR willincreasingly become a part of our life.15
