6. Introduction
Virtual reality is a simulated3Denvironment that
enables users to explore and interact with a virtual
surrounding in a way that approximates reality, as
it is perceived through the users' senses. The
environment is created withcomputer hardware
and software.

7. Evolution of Virtual Reality
7
Created by Morton Heilig in 1962, it was
a multi-sensory theatre that offered 3D
visuals, stereo sound, smells, wind, and
vibrations.
Released in 1995, it was a tabletop console that
presented black and red 3D graphics, but had no
head tracking and caused eye strain and headaches.
Released in 2016, it features high-
resolution displays, precise head and
motion tracking, touch controllers, and a
vast library of games and experiences.
New VR theme parks like The Void and Dreamscape
Immersive offer interactive, multisensory, and social
experiences for groups of users, using backpack PCs
and haptic vests.

TYPES OF VIRTUAL
REALITY
•Non-immersive Virtual Reality.
•Fully Immersive Virtual Reality.
•Semi-Immersive Virtual Reality.
•Augmented Reality.
•Collaborative VR

9. Non-immersive Virtual Reality.
9
Non-immersive virtual reality (VR) is a type of
VR in which the user is not fully immersed in
the virtual environment. The user is still aware
of their physical surroundings and can interact
with them. Non-immersive VR experiences can
be accessed on a computer screen or mobile
device.
Examples of non-immersive VR include 360-
degree videos and virtual tours.

10. Semi-immersive virtual reality is a type of VR
that falls somewhere between non-immersive and
fully immersive VR. The user is partially
immersed in the virtual environment, but they are
still somewhat aware of their physical
surroundings. Semi-immersive VR experiences
can be accessed using a variety of equipment,
including HMDs, projection systems, and VR
caves.
Examples of semi-immersive VR include flight
simulators and medical training simulators.

Semi-Immersive Virtual Reality

11. Fully Immersive Virtual Reality.
Fully immersive virtual reality is a type of VR in
which the user is completely immersed in the
virtual environment. The user can no longer see
or interact with their physical surroundings. Fully
immersive VR experiences require the use of a
head-mounted display (HMD).
Examples of fully immersive VR include video
games, movies, and educational experiences.
11

12. 12
Collaborative VR
Collaborative VR is a type of VR that
allows multiple users to interact with
each other in the same virtual
environment. Collaborative VR
experiences can be used for a variety of
purposes, such as training, education, and
gaming.

13. 13
How Does Virtual Reality Work?
Head-Mounted Display (HMD) Tracking Systems
An HMD contains two small screens, one
for each eye, that display stereoscopic
images. It may also have built-in
headphones and sensors for tracking head
position and movement.
Tracking systems use a combination of
cameras, infrared light, or other sensors
to capture and interpret the user's
movements in real-time and adjust the
VR world accordingly.
A powerful computer or gaming console is
needed to render the complex 3D graphics
and simulate the physics and interactions
of the virtual world in real-time.
Controllers or gloves allow the user to
interact with the virtual world using their
hands, fingers, and gestures. They may
have buttons, triggers, or haptic feedback
to enhance immersion.
Computer or Console Controllers or Gloves

14. Exploring the Boundaries of Virtual Reality:
LIMITLESS POSSIBILITIES
Virtual reality opens a
world of limitless
possibilities, allowing
users to explore new and
immersive experiences.
BREAKING BARRIERS
Virtual reality breaks the
barriers of physical
limitations, enabling users
to visit places and engage
in activities that were
previously unimaginable.
UNLEASHING CREATIVITY
Virtual reality unleashes
creativity by providing a
platform for artists,
designers, and developers
to create unique and
immersive digital worlds.
14

15. Virtual Reality in Education and Training
Virtual reality has revolutionized the way education and training are delivered. It provides
immersive and interactive experiences that enhance learning and skill development.
15
Enhanced
Learning
Realistic
Simulations
Virtual Field
Trips
Virtual reality enables realistic
simulations that allow students
to practice and apply their
skills in a safe and controlled
environment
Virtual reality allows students to
explore different places and
cultures without leaving the
classroom, enhancing their
understanding and empathy.
Virtual reality offers a highly
engaging and interactive
learning environment that
improves knowledge retention.

16. PAIN MANAGEMENT SURGICAL TRAINING
16
The Impact of Virtual Reality in Healthcare
MENTAL HEALTH
TREATMENT
Virtual reality is used to
distract patients from pain
during medical
procedures, reducing the
need for anesthesia and
pain medication
Virtual reality simulations
provide surgeons with
realistic training scenarios,
improving their skills and
reducing surgical errors.
Virtual reality is used for exposure
therapy in treating phobias,
PTSD, and anxiety disorders,
offering a controlled and safe
environment for patients.
