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.
WORKING OF VR
DESIGN OF HMD
OCULUS RIFT
HOW IT WORKS ?
VR-HARDWARE HMD’s
CAVE
DATA GLOVES
VR SIMULATORS
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.
