Types of Virtual Reality
 Devices used in Virtual Reality
 Applications of Virtual Reality
 Conclusion
WHAT IS VIRTUAL REALITY?
 Virtual Reality refers to a high-end user interface that involves
real-time simulation and interactions through multiple sensorial
channels.
 Virtual Reality means feeling an imaginary (virtual) world,
rather than the real one. The imaginary world is a simulation
running in a computer. The sense data is fed by some system to
our brain.
 Virtual Reality allows a user to interact with a computer-
simulated environment, be it a real or imagined one.
HISTORY OF VIRTUAL REALITY
1950’s visionary cinematographer Morton Heilig built a single
user console called Sensorama. This enabled the user watch
television in three dimensional ways.
In 1961, Philco Corporation engineers developed the first HMD
known as the Headsight.
It was in 1965 IVAN SUTHERLAND envisioned what he
called the “Ultimate Display.”
In 1988, commercial development of VR began.
In 1991, first commercial entertainment VR system "Virtuality"
was released.
TYPES OF VIRTUAL REALITY
VR Systems can be divided into three groups
• Non-immersive systems (like workstations)
See information about the real world, presented via computer
- location based services, GIS .
• Augmented reality systems (like HMD)
Stay in real world, but see simulated objects.
• Immersive systems (like CAVE)
See simulated world and "be" in that simulated world.
DEVICES USED IN VIRTUAL REALITY
 HEAD MOUNTED DISPLAY (HMD)
 CAVE AUTOMATIC VIRTUAL ENVIRONMENT (CAVE)
 DATA GLOVES  DATA SUIT
APPLICATIONS OF VIRTUAL REALITY
Business:
• Virtual reality is being used in a number of ways by the
business community which include:
• Virtual tours of a business environment.
• Training of new employees.
• A 360 view of a product.
Training:
• Virtual reality environments have been used for training
simulators.
• Examples include flight simulators, battlefield simulators for
soldiers,paratrooping.
Engineering and Design:
• VR is widely used in engineering and designing process.
• It gives better understanding of the design and facilitates
changes wherever necessary
• It helps to reduce the time and cost factor.
Examples: Building construction, car designing.
Medical:
• Healthcare is one of the biggest adopters of virtual reality which
encompasses surgery simulation, phobia treatment, robotic
surgery and skills training.
• VR finds its application in nursing, dentistry, health issues for
the disabled.
Entertainment:
• The entertainment industry is one of the most enthusiastic
advocates of virtual reality, most noticeably in games and
virtual worlds.
• Virtual Museum, e.g. interactive exhibitions
• Gaming
• Virtual theme parks
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.
