slide3:What is virtual reality?
Virtual reality or virtual realities (VR), which can be referred to as immersive multimedia or computer-simulated reality, replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact in that world. Virtual realities artificially create sensory experiences, which can include sight, touch, hearing, and smell.
slide4:TYPES OF VIRTUAL REALITY
VR Systems can be divided into three groups:

1)NON-IMMERSIVE SYSTEMS(like workstations)

“through-the-window”
Large display,but doesn’t surround the user.
Desktops,LCD TV’s
Ex:Playstation
slide5:
2)Augmented reality
HYBRID SYSTEMS(graphics on top of realworld)
also called:AUGMENTED REALITY Systems
AR integrate the computer-generated virtual objects into the physical world. Stay in real world,but see simulated objects.

This involves literally augmenting reality with
virtual information.
slide6:
3) IMMERSIVE SYSTEMS(like HMD or CAVE)
See simulated world and “be”
in that simulated world.
It basically is an artificial reality that projects
you into a 3D space generated by the
computer.

Virtual reality

  1. 1. VIRTUAL REALITY PRESENTATION BY:- SHRUTI SINGH B.TECH IT 2nd yr. 1413213063
  2. 2. OVERVIEW  WHAT IS VIRTUAL REALITY?  TYPES OF VIRTUAL REALITY  DEVICES USED IN VIRTUAL REALITY  ARCHITECTURE  APPLICATIONS  WHO IS DOING IT NOW?  WHAT’S SO UNIQUE?  VRML  ADVANTAGES &DISADVANTAGES  FUTURE  CONCLUSION
  3. 3. WHAT IS VIRTUAL REALITY? Virtual reality or virtual realities (VR), which can be referred to as immersive multimedia or computer- simulated reality, replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact in that world. Virtual realities artificially create sensory experiences, which can include sight, touch, hearing, and smell.
  4. 4. TYPES OF VIRTUAL REALITY VR Systems can be divided into three groups: 1)NON-IMMERSIVE SYSTEMS(like workstations) “through-the-window” • Large display,but doesn’t surround the user. • Desktops,LCD TV’s • Ex:Playstation
  5. 5. 2)AUGMENTED REALITY HYBRID SYSTEMS(graphics on top of realworld) also called:AUGMENTED REALITY Systems  AR integrate the computer-generated virtual objects into the physical world. Stay in real world,but see simulated objects.  This involves literally augmenting reality with virtual information.
  6. 6. 3) IMMERSIVE SYSTEMS(LIKE HMD OR CAVE) See simulated world and “be” in that simulated world. • It basically is an artificial reality that projects you into a 3D space generated by the computer.
  7. 7. DEVICES USED IN VIRTUAL REALITY HMD DATAHMD DATA GLOVES DATA SUIT CAVE AUTOMATIC VIRTUAL ENVIRONMENT (CAVE)
  8. 8. ARCHITECTURE OF A VR SYSTEM  Input Processor, Simulation Processor, Rendering Processor and World Database. Input Processor Rendering Processor World Database Simulation Processor visual, auditory, haptic, touch… Position & Orientation
  9. 9. APPLICATIONS • ARCHITECTURE • TRAINING • MEDICINE • ENGINEERING AND DESIGN • E-COMMERCE • ENTERTAINMENT • MANUFACTURING
  10. 10. ENTERTAINMENT MEDICINE (SURGERY) EDUCATION & TRAINING
  11. 11. WHO IS DOING IT NOW?
  12. 12. WHAT’S SO UNIQUE ? Wearable tech make you think you're standing on Mars when you're actually about to bump into the kitchen counter. Total immersion is what everyone making a VR headset, game or app is aiming towards - making the virtual reality experience so real that we forget the computer, headgear and accessories and act exactly as we would in the real world. Like Earphones control your audio sense, VR headsets control the vision - immersion is the best part.
  13. 13.  VR IN PROGRAMMING LANGUAGE: VIRTUAL REALITY MODELLING LANGUAGE(VRML) Virtual Reality Modelling language is a standard file format for representing 3D interactive vector graphics,design particularly with World Wide Web in mind. Ex: You can view a room and use controls to move the room as you would experience it if you were walking through it in real space. CHARACTERISTICS: o Not a programming language like c++ or java. o Descriptive (rather than procedural) like HTML. o File formats contains human readable and editable ASCII text.
  14. 14. ADVANTAGES &DISADVANTAGES  ADVANTAGES 1) Virtual reality creates a realistic world . 2) It enables user to explore places. 3) Through Virtual Reality user can experiment with an artificial environment. 4) Virtual Reality make the education more easy. DISADVANTAGES 1) The equipments used in virtual reality are very expensive. 2) It consists of complex technology. 3) In virtual reality environment we can’t move by our own, like in the real world.
  15. 15. FUTURE OF VR • Virtual Reality is a growing industry. • 3D interfaces will replace the windows based ones. • Low price. • Phone manufacturers will give free VR headset. • Revolution in gaming industries. • Huge demand for VRML programmers in near future. • PC and specialized hardware are getting better , faster and cheaper because of development in VR.
  16. 16. CONCLUSION • In every generation, there is a technology that defines them. • For our parents, it was the internet. For us, it was the iPhone. • For the next generation — it will be virtual reality. • So a Virtual Reality is synthetic sensory experience which may one day be indistinguishable from the real physical world.
