INTRODUCTION

Virtual Reality(VR)? Virtual Reality refers to a high-end user interface

that involves real-time simulation and interactions through multiple sensorial channels.

Virtual reality is a computer generated world

with which the user can interact.Interaction can vary from looking around to

interactively modifying the world.

HISTORY OF VR1950’s visionary cinematographerMorton H Eilig built a single user Console called Sensorama . This enabled the user watchtelevision in three dimensional ways. 

In 1961, Philco Corporation engineers developed the first HMD known as the Headsight.

HISTORY OF VR

TYPES OF VR SYSTEM

Immersive Virtual Reality Augmented Virtual Reality Desktop (Window on a World) Virtual Reality Video Mapping Virtual Reality

IMMERSIVE VR It is basically a feeling of involvement of the user in the

virtual world . The user has no visual contact with the physical word. Often equipped with a Head Mounted Display. This unique combinations where the user can immerse as well interact with the simulations is known as Telepresence

DESKTOP VR Desktop-based virtual reality involves

displaying a 3-dimensional virtual world on a regular desktop display without use of any specialized movement-tracking equipment.

Modern computer games can be used as an example

VIDEO MAPPING VR

ARCHITECTURE OF VR SYSTEM Input Processor, Simulation Processor,

Rendering Processor and World Database.

APPLICATIONS OF VIRTUAL REALITY Entertainment

More vivid Move exciting More attractive

Medicine - Practice performing surgery.- Perform surgery on a remote patient.- Teach new skills in a safe, controlled

environment.

APPLICATIONS OF VIRTUAL REALITY

Manufacturing Easy to modify Low cost High efficient

Education & Training Driving simulators. Flight simulators. Ship simulators. Tank simulators.

CONCLUSION• Virtual Reality is a growing industry.• PC and specialized hardware are getting better, faster and

cheaper because of development in VR.• In the past, computing power has doubled approximately

every 18 months. 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.
