The document discusses the history and types of virtual reality. It describes how virtual reality allows users to experience simulated, imaginary worlds through computer simulations. The document outlines the major types of virtual reality systems - immersive, non-immersive, and window-on-world. It also discusses the hardware used in virtual reality like input devices (wands, gloves) and output displays. Applications of virtual reality mentioned include military, healthcare, education, and entertainment. Both advantages like realistic simulations and disadvantages like high costs are outlined.

3. What is Virtual Reality?
Virtual Reality means feeling the imaginary(virtual) world,
rather than the real one. The imaginary world is a simulation
running in a computer.

4. History
More than one person has been involved in the development of
this technological system.
In 1950’s visionary cinematography Morton Heilig built a single
user console called Sensorama. This enabled the user watch
television in 3 dimensional ways.

5.  Immersive Virtual Reality
 Non-Immersive Virtual Reality
 Window on world Virtual Reality

6. •Immersive Virtual Reality
Immersive Virtual Reality
Immersion into virtual reality is a perception of being
physically present in a non-physical world.
Elements of virtual environments that increase the
immersiveness of the experience:
1. Continuity of surroundings
2. Conformance to human vision
3. Freedom of movement
4. Physical interaction
5. Physical feedback

7. Non-Immersive Virtual Reality
 Large display, but doesn’t surround the user.

8. Window on world Virtual Reality
 Desktop- based Virtual Reality involves displaying a
3-dimensional virtual on regular desktop display without use of
any specialized movement tracking environment.

9. Hardware Devices
 Input Devices
 Output Devices

10. A variety of input devices allow the user to navigate through a
virtual environment and to interact with virtual objects. Directional
sound, tactile and force feedback devices, voice recognition and
other technologies are being employed to enrich the immersive
experience and to create more "sensualized"interfaces.

12. The head-mounted display (HMD) was the first device providing its wearer with
an immersive experience. A typical HMD houses two miniature display screens
and an optical system that channels the images from the screens to the eyes,
thereby, presenting a stereo view of a virtual world. As a result, the viewer can
look around and walk through the surrounding virtual environment.

14. Applications of Virtual Reality
1. Virtual Reality in the Military

15. 2.Virtual Reality in Healthcare

16. 3.Virtual Reality and Education

17. 4.Virtual Reality and Scientific Visualization

18. 5.Virtual Reality in Entertainment

20. Advantages and Disadvantages
Advantages
 Virtual reality creates a
realistic world.
 It enables user to explore
places.
 Through Virtual Reality
user can experiment with
an artificial environment.
 Virtual Reality make the
education more easily and
comfort.
 The equipments used in
virtual reality are very
expensive.
 It consists of complex
technology.
 In virtual reality
environment we cant
move by our own like in
the real world.
Disadvantages

21.  As Virtual Reality software becomes more powerful and its hardware
more sophisticated, not to mention more affordable, there will be a
number of challenges that the industry must face head-on.
 The focus should remain on the positive contributions this
technology can make to society. From better healthcare training and
education, to active rather than sedentary gaming, there are a
number of clear benefits to embracing the exciting developments
being made in the world of VR.
