This document discusses virtual reality and its types and applications. It defines virtual reality as a computer-generated immersive or wide field multi-sensory information which tracks users in real time. The main types discussed are immersive virtual reality, window on world virtual reality, and telepresence virtual reality. Applications mentioned include architecture, medicine, engineering and design, entertainment, training, and manufacturing. Advantages include creating realistic worlds and enabling experimentation, while disadvantages include high equipment costs and inability to fully replicate real world movement.

2. Virtual Environment Introduction
 A computer generated
world with which user can
interact is calledVirtual
Environment.
 This interaction can vary
from looking around to
interactively modifying the
world.

3. Definition
 A computer generated immersive or wide field multi
sensory information which tracks user In real time.

4. Types of Virtual reality
 There are following
types of virtual reality.
Immersive

5.  The ImmersiveVirtual Reality System
completely involve the users personal
viewpoint in the virtual world Like a
person experiencing cave scene
Immersive virtuAL REALITY

6.  Some systems uses conventional
computer monitor to display visual
world.This sometimes called Desktop
Virtual reality orWindow onWorld
(WoW)
Window on world virtuAL REALITY

7. • Telepresence is variation to visualize completely
computer generated world.
• This is a technology which links the remote sensors
with the senses of human operator in real world.
• Fire fighters uses remote controlled vehicles to
operate some dangerous conditions.This vehicles
are equipped withTelepresence systems.
Tele Presence VIRTUAL REALITY

9. • Merging theTelepresence andVirtual reality
systems gives the mixed virtual reality or
seamless simulation.
• In this type of virtual reality user can see,
Hear virtual world and can operate that
world by usingTelepresence.
Mixed VIRTUAL REALITY

12. ImageGenerators
• One of the most time consuming task inVirtual Reality is
generation of images.
• Fast computer graphics opens a large range of
applications aside from virtual reality.
• So there is a market demand for graphic acceleration for
long while.

14. Manipulation&controldevices
• One key element for interaction to the virtual world that
is tracking the position of real world objects such as head
or hand.
• The conventional control devices are mouse, trackball, or
joystick
• Some common usedVR control device is Instrumented
Glove.
• The use of Glove is to manipulate objects in the
computer by using inbuilt sensors which fitted on fingers
for tracking.

16. StereoVision
• Stereo vision is also included in virtual reality system.
• This is accomplished by creating two different images of
the world one for each eye.
• The images can projected through differently polarized
filters this filters are placed in front of our eyes.
• When this images are shown on this vision in rapid speed
then brain fuses this two images in a single image & can
get 3d experience.

19. ARCHITECTURE DESIGING

20.  The medical field uses virtual reality
in many ways.
 The most common implementation
of the technology is to combine
images provided by other scans and
merge them to present the details,
using medical imaging technology
 This helps doctors diagnose problems
without performing surgery.

Entertainment Field
• In high definitionTelevisionsVR
is used for highly resolute
output
• Also for motion games

Training Field
United states usesVR as flight
simulator to train pilots.
WithVR training huge saving of
fuel, electricity, wear & tear could
be effected.

26. ADVANTAGES OFVIRTUAL
REALITY
1)Virtual reality creates a realistic world
2) It enables user to explore places.
3)ThroughVirtual Reality user can
experiment with an artificial environment.
4)Virtual Reality make the education more
easily and comfort.

27. 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.
