  1. 1. A COLLOQUIUM (611) PRESENTATION ON “VIRTUAL REALITY”
  2. 2. Under the Guidance of : Submitted by: Dr.Manju Gupta Kapil Goswami Head of the Department (1109814061) Department-IT 2013-2014 Institute of Management Studies, Noida
  3. 3. CONTENTS 1. INTRODUCTION & OBJECTIVE 2. DESCRIPTION OF THE VIRTUAL REALITY 3. APPLICATION AREAS WITH EXAMPLES
  4. 4. INTRODUCTION  Virtual reality is an artificial environment that is created with software and presented to the user in such a way that the user suspends belief and accepts it as a real environment.  On a computer, virtual reality is primarily experienced through two of the five senses: sight and sound.
  5. 5.  The simplest form of virtual reality is a 3-D image that can be explored interactively at a personal computer, usually by manipulating keys or the mouse so that the content of the image moves in some direction or zooms in or out.
  6. 6. OBJECTIVE The main objective of Virtual Reality is to create real environment of imaginary objects which is easy to operate and understand by the user or a person like: - FLIGHT SIMULATORS.
  7. 7. DESCRIPTION OF VIRTUAL REALITY 1. What is the Concept of Virtual Realty?? 2. Why Virtual Reality is needed?? 3. How does Virtual Reality Architecture work??
  8. 8. 1. What is the Concept of Virtual Reality??  Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels.  Most virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones.
  9. 9. Fig:-3D Picture
  10. 10. Brief History In 1950s, flight simulators were built by US Air Force to train student pilots. In 1965, a research program for computer graphics called “The Ultimate Display” was laid out. In 1988, commercial development of VR began. In 1991, first commercial entertainment VR system "Virtuality" was released.
  11. 11. 2. Why Virtual Reality is needed??  Virtual Reality is able to immerse you in a computer-generated world of your own making: A room, A city, The interior of human body.  With VR, you can explore any uncharted territory of the human imagination.
  12. 12. Types of Virtual Reality A. 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.
  13. 13.  Immersive VR Components i. The Head-Mounted Display (HMD) –  was the first device providing its wearer with an immersive experience.  A typical HMD houses two miniature display screens and an optical system that channels the images from the screens to the eyes, thereby, presenting a stereo view of a virtual world.  As a result, the viewer can look around and walk though the surrounding virtual environment.
  14. 14. Fig:-The Head Mounted Display (HMD)
  15. 15. ii. The CAVE (Cave Automatic Virtual Environment) –  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.
  16. 16. Fig:-The CAVE (Cave Automatic Virtual Environment)
  17. 17. iii. Glove :-  that can sense the position of the finger which can be used to control and interact with the virtual images being displayed.
  18. 18. B. Augmented VR-  Integrate the computer-generated virtual objects into the physical world which become in a sense an equal part of our natural environment.
  19. 19. 3.How does an Architecture of Virtual Reality System work?? Input Processor Rendering Processor World Database Simulation Processor visual, auditory, haptic, touch… Position & Orientation
  20. 20. Description of above architecture There are mainly 4 components as follows:- 1. Input processor:-  Control the devices used to input information to the computer. The object is to get the coordinate data to the rest of the system with minimal lag time.  Keyboard, mouse, 3D position trackers, a voice recognition system, etc.
  21. 21. 2. Simulation processor:-  Core of a VR system.  Takes the user inputs along with any tasks programmed into the world and determine the actions that will take place in the virtual world. 3. Rendering processor:-  Create the sensations that are output to the user.
  22. 22.  Separate rendering processes are used for visual, auditory, haptic and other sensory systems. 4. World Database :-  Store the objects that inhabit the world,  Scripts that describe actions of those objects.
  23. 23. Virtual Reality Modeling Language (VRML) Standard language for interactive simulation within the World Wide Web. Allows to create "virtual worlds" networked via the Internet and hyperlinked with the World Wide Web.  VR models can be viewed by Netscape or IE with a browser plug-in.
  24. 24. Characteristics of Virtual Reality Modeling Language (VRML)  Not a programming language like c++ or java.  Descriptive (rather than procedural) like HTML.  File formats contains human readable and editable ASCII text.
  25. 25. Software packages available in market  Multiverse (Freeware)  Virtual Reality Studio  Sense8 World Tool Kit (WTK)  Autodesk Cyberspace Development kit
  26. 26. Application Areas where Virtual Reality is used:- 1. Entertainment  More vivid  Move exciting  More attractive
  27. 27. 2. Medical  Practice performing surgery.  Perform surgery on a remote patient.  Teach new skills in a safe, controlled environment.
  28. 28. 3. Manufacturing  Easy to modify  Low cost  High efficient
  29. 29. 4. Education & Training  Driving simulators.  Flight simulators.  Ship simulators.  Tank simulators.
