Virtual reality (VR) is an artificial environment that is created with computer hardware and software and presented to the user in a way that makes them feel like they are experiencing a real environment. There are different types of VR systems, including window-on-world systems which use monitors, immersive VR with head mounted displays, telepresence which links sensors to human operators, and mixed reality systems. Important factors in VR systems include visual realism, image resolution, frame rate, and latency. VR has applications in areas like education, medicine, entertainment, and more and its future uses are still developing as customized applications are created.

- 1. VIRTUAL REALITY Presented by: Name: Sharmin Sarkar Roll No.: 34401215016 Registration No.: 153441010016
- 2. OVERVIEW • Introduction • Why VR? • Types of VR System • VR Design Components • Important Factors in VR Systems • VR Devices • Future of VR 1
- 3. INTRODUCTION • It is an artificial environment created with computer hardware and software and presented to the user in such a way that it appears and feels like a real environment. • In 1991, first commercial entertainment VR system “Virtuality” was released. 2
- 4. WHY VR? • VR is able to immerse you in a computer generated world of your own making: o a room o a city o the interior of human body • With VR, you can explore any uncharted territory of the human imagination. 3
- 5. TYPES OF VR SYSTEM • Window on World (WoW) • Immersive VR • Tele-presence • Mixed Reality(Augmented Reality) • Distributed VR 4
- 6. TYPES OF VR SYSTEM • Window on World (WoW) o Also called Desktop VR. o Using a conventional computer monitor to display the 3D virtual world. 5
- 7. TYPES OF VR SYSTEM • Immersive VR o Completely immerse the user's personal viewpoint inside the virtual 3D world. o The user has no visual contact with the physical word. o Often equipped with a Head Mounted Display (HMD). 6
- 8. TYPES OF VR SYSTEM • Tele-presence o A variation of visualizing complete computer generated worlds. o Links remote sensors in the real world with the senses of a human operator. The remote sensors might be located on a robot. Useful for performing operations in dangerous environments. 7
- 9. TYPES OF VR SYSTEM • Mixed Reality (Augmented Reality) o The seamless merging of real space and virtual space. o Integrate the computer-generated virtual objects into the physical world which become in a sense an equal part of our natural environment. 8
- 10. TYPES OF VR SYSTEM • Distributed VR • A simulated world runs on several computers which are connected over network and the people are able to interact in real time, sharing the same virtual world. 9
- 11. VR DESIGN COMPONENTS VR comprises of six main components: • Virtual World (Database of scenes) • Graphic engine (Define viewport) • Simulation engine (control change w.r.t users) • User interface • User Inputs • User Outputs 10
- 12. • Visual Realism “fool the user’s senses” • Image Resolution “environment based” • Frame Rate “continuous &smooth picture” • Latency “degree of realism” IMPORTANT FACTORS IN VR SYSTEMS 11
- 13. Some well-known VR-devices are: • Cyber Touch Gloves • Head Mounted Display • Boom • Cave • Data Suit • Omni directional Treadmills • Cyber Carpet • Virtual Globe • Virtual Keyboard VR DEVICES 12
- 14. • Flight Simulation • Car Drive Learning APPLICATIONS OF VR 13
- 15. • Architecture • Hang-glider experience APPLICATIONS OF VR 14
- 16. • Medicine • Education APPLICATIONS OF VR 15
- 17. • Entertainment and so on…. APPLICATIONS OF VR 16
- 18. • It is difficult to predict the future of virtual reality with confidence. It is still very much in the development stage with many users creating their own customized applications and setups to suit their needs. FUTURE OF VR 17
