  4. 4. Introduction: <ul><li>Computer generated artificial reality. </li></ul>MBA-1 (B) EVENING NUML
  5. 5. History: <ul><li>Term created by Antonin Artaud, a French actor </li></ul><ul><li>Has roots in fiction and theater </li></ul><ul><li>Technology begun in 1950’s </li></ul><ul><li>First commercial VR system created in 1988, named “Virtuality” </li></ul><ul><li>After that progress and search continued </li></ul>MBA-1 (B) EVENING NUML
  6. 6. How It Works: MBA-1 (B) EVENING NUML <ul><li>Virtual reality environments are primarily visual experiences </li></ul><ul><li>User can interact either through standard input devices, such as, mouse key-board or through multi-modal devices, like, head-gear or hand-gloves </li></ul>
  7. 7. Types: MBA-1 (B) EVENING NUML <ul><li>Adventure Games - Textually described virtual worlds, where the user perceives the virtual environment through mental images </li></ul><ul><li>Desktop -3-D virtual environment, graphically displayed on a desktop computer monitor </li></ul><ul><li>Projected -3-D environment projected onto a screen </li></ul><ul><li>Semi-Immersive -The user has partial contact with the real world </li></ul><ul><li>Immersive -The user has no contact with the physical world </li></ul>
  8. 8. Technologies: <ul><li>1-Head-Mounted Display (HMD) - A helmet or a face mask providing the visual and auditory displays. </li></ul>MBA-1 (B) EVENING NUML
  9. 9. 2-Binocular Omni-Orientation Monitor (BOOM)- Head-coupled stereoscopic display device MBA-1 (B) EVENING NUML
  10. 10. <ul><li>3-Cave Automatic Virtual Environment (CAVE) - Provides the illusion of immersion by projecting stereo images on the walls and floor of a room-sized cube. </li></ul>MBA-1 (B) EVENING NUML
  11. 11. <ul><li>4-Data Glove - Enables natural interaction with virtual objects by hand gesture recognition . </li></ul>MBA-1 (B) EVENING NUML
  12. 12. <ul><li>5-Control Devices - Control virtual objects in 3 dimensions . </li></ul>MBA-1 (B) EVENING NUML
  13. 13. Components of VR System: <ul><li>Input Process or, Simulation Processor, Rendering Processor and World Database . </li></ul>Input Processor Rend er ing Processor World Database Simulation Processor visual, auditory, haptic, touch … Position & Orientation MBA-1 (B) EVENING NUML
  14. 14. MBA-1 (B) EVENING NUML <ul><li>Input Processor: Control the devices used to input information in the computer </li></ul><ul><li>Simulation Processor: Takes the user inputs along with any tasks programmed into the world and determine the actions that will take place in the actual world </li></ul><ul><li>Rendering Processor: Creates the sensations that are output to the user </li></ul><ul><li>World Database: Stores the objects that inhabit the world </li></ul>
  15. 15. Applications/Implementations: <ul><li>Entertainment </li></ul><ul><ul><li>More vivid </li></ul></ul><ul><ul><li>Move exciting </li></ul></ul><ul><ul><li>More attractive </li></ul></ul>MBA-1 (B) EVENING NUML
