    Virtual Reality
  • Virtual Environment (VE)
    • A computer generated world with which the user can interact
    • Interaction can vary from looking around to interactively modifying the world.

  • Definition
    • What is virtual reality(VR)?
    • A computer generated,immersive
    • (or wide field),multi-sensory information
    • program which tracks a user in real
    • time.

  • History Virtual Reality Virtual Reality movie grosses $750M worldwide Larry and Andy Wachowski 1999 Virtual Reality Modeling Language Silicon Graphics 1995 A look at the possible negative side of VR Stephen King (Official Website) 1992 The Holodeck, idea of immersive VR Michael Piller (Writer) 1987 The term 'Cyberspace' William Gibson (His assistant) 1984 First virtual environment Myron Krueger 1983 The first computer- generated movie Bonnie MacBird ( Writer) 1982 Interaction through body movement Dan Sandin , Richard Sayre and Thomas Defanti 1977 The beginnings of VR Ivan Sutherland 1965 Why it was important Person(s) Responsible Year

    Virtual Reality
  • What is Immersive VR?
    • A type of VR in which the user becomes immersed (deeply involved) in a virtual world. it is also a form of VR that uses computer related components.
    Virtual Reality
  • Types of Non-immersive VR
    • Text-based VR: when a reader of a certain text form a mental model of this virtual world in their head from the description of people , places and things.
    • Augmented VR: the idea of taking what is real and adding to it in some way so that user obtains more information from their environment.

    Virtual Reality
  • Architecture
    • An area in which virtual reality has tremendous potential is in architectural design. Already being created are architectural "walk-throughs" that allow designers and clients to examine homes and office buildings, inside and out, before they're built. With virtual reality, designers can interactively test a building before construction begins.
    Virtual Reality
  • Medicine
    • researchers are using virtual reality technology to create 3-D ultrasound images to help doctors diagnose and treat congenital heart defects in children
    • The medical application of VR was stimulated initially by the need of medical staff to visualise complex medical data, particularly during surgery and for surgery planning, and for medical education and training.
    Virtual Reality
  • Training
    • United States: The military used it as flight simulators to train pilots.
    • National Aeronautics and Space Administration (NASA) use VR technology to construct a model of the Hubble Space Telescope (HST) .in September, 1993, approximately 100 members of the NASA HST flight team received over 200 hours of training using the VR...
    Virtual Reality
  • Devices
    • Head Mounted Displays (HMD):
    • was the first device providing its wearer with an immersive experience. Evans and Sutherland demonstrated a head-mounted stereo display already in 1965.
    Virtual Reality
  • Binocular Omni-Orientation Monitor (BOOM)
    • BOOM is a head coupled stereoscopic display device. Screens and optical system are housed in a box that is attached to a multi-link arm.
    Virtual Reality
  • Cave Automatic Virtual Environment (CAVE)
    • A room with projections on all walls, floor and ceiling
    • The users wear shutter glasses to get a 3D view of the world.
    • The users are able to move and control the environment with some kind of input mechanism
      • Camera
      • Device in hand
    Virtual Reality
  • 3D VIDEO Eyewear
    • winner of a 2005 & 2006 Consumer Electronics Show Design Award.
    Virtual Reality VR Price: $499.00
  • Virtual reality Modeling Language (VRML)
    • Most exciting is the ongoing development of VRML on the World Wide Web. In addition to HTML (Hypertext Markup Language), that has become a standard authoring tool for the creation of home pages, VRML provides three-dimensional worlds with integrated hyperlinks on the Web. Home pages become home spaces.
    Virtual Reality
  • Characteristics Of VRML
    • Not a programming language like c++ or java
    • Descriptive (rather than procedural) like HTML
    • File formats contains human readable and editable ASCII text
    Virtual Reality
  • Job Opportunities
    • The Swiss Federal Institute of Technology's (EPFL) Computer Graphics Lab has several openings for PhD students and Post Doctoral fellows in the areas of Computer Animation, Virtual Reality, and Computer Vision. Selected candidates will work on one or several of the following topics:
    • Motion Control of virtual characters (kinematics, dynamics, and capture)
    • Human body deformations
    • Parametric animation models (e.g. running) from video analysis
    • Interaction between virtual humans and objects in the Augmented Reality framework.
    Virtual Reality
  • Bam and its Cultural Landscape
    • After the earthquake of the 26th December 2003 and the immense destruction of the Bam heritage in Iran, the reconstruction of the ruins especially of the citadel of Bam has become an important task for experts.
    • first phase of the project were to develop the 3Dimensional models of 7 case studies inside the citadel of Bam (Main gate,Bazaar,Tekkiyeh (religious plaza), Mosque, Sistani house, barrack, stable, four season reception room
    Virtual Reality
  • Cont….
    • The team of drawing the 3D models consisting of in Japan from Waseda University and the team of Raaz Ahang architectural firm in Iran from University of Tehran has made a tremendous effort to build the 3D models.

  • Future
    • In the past, computing power has doubled approximately every 18 months, a trend that is known as Moore’s Law. If this is the case then we should have a computer powerful enough to run immersive VR programs in our own homes by the year 2037.
    Virtual Reality 99% of the world’s computing capacity will be non-human 2029 10% of the world's computing power was non-human 1999
