Virtual Reality (VR) Technology-A realistic three-dimensional image or artificial environment that is created with a mixture of interactive hardware and software, and presented to the user in such a way that the any doubts are suspended and it is accepted as a real environment in which it is interacted with in a seemingly real or physical way.

1. Virtual Reality

2. What is Virtual Reality?
The definition of virtual reality comes, naturally, from the
definitions for both ‘virtual’ and ‘reality’. The definition of
‘virtual’ is near and reality is what we experience as human
beings.

3. Why have virtual reality?
There are a wide variety of applications for virtual reality which include:
• Architecture
• Sport
• The Arts
• Medicine
• Medicine

4. Types of Virtual Reality
• Non-Immersive
• Fully-Immersive
• Semi-Immersive

5. How Does Virtual Reality Work?

6. Key Components in a Virtual Reality System
• Pc(personal computer)
• head-mounted display
• Input devices-
• Joysticks
• Force Balls/Tracking Balls
• Controller Wands
• Data Gloves
• Trackpads
• On-Device Control Buttons
• Motion Trackers/Bodysuits
• Treadmills
• Motion Platforms

7. How Virtual Reality Headsets Work (Inside)
•Inside of each virtual reality head-
mounted display (HMD) is a series of
sensors, individual eye displays, lenses,
and display screen(s), among other
various components

8. Key Components Inside of a Virtual
Reality Headset
Sensors-The three most common sensors in a virtual
reality headset are:
• magnetometers
• accelerometers
• gyroscopes

9. Lenses-Lenses lie between your eyes and pixels on the display
screen(s). They focus and reshape the picture for each eye by angling
two 2D images to mimic how each of our eyes take in views of the
world.
Display Screen-Display screens show the images that user view
through the lenses. They are typically LCD and receive video feed
from the computer or smartphone. Depending on the headset.

10. •Processing-The processing power required by virtual
reality systems can be broken down into several categories:
• Input processor
• Simulation processor
• Rendering processor
