VIRTUAL REALITY IS
-Artificial Environment
-Interaction with human senses
-Input from persons actions and reactions.

Why is Virtual reality needed?
It will take us to the world generated by
Computer such as a room, or interior of
Human body.

In 1950’s flight stimulators were built by US air force
to train student pilots.
In 1965, a research program for computer graphics
“the ultimate layout” was laid out.
In 1988, the commercial development of VR
was developed.
In 1991, first commercial entertainment VR system
“virtuality” was developed.

Target segments

Devices used
In VR
Technology

HMD(Head Mounted Display)
 Worn on head like a helmet or
face mask.
 Has a small display optic in front
of one eye (Monocular HMD) or
can have it on each eye
(Binocular HMD) to reproduce a
stereoscopic vision.

CAVE (Cave Automatic Virtual
Environment)
Surround-screen
Projection-based
 Coupled with head and hand
tracking systems.

BOOM (Binocular Omni-Orientation
Monitor)
 Head-coupled stereoscopic display device.

Data gloves
Mounted along the fingers
which accurately measure the
position and movement of the
fingers and wrist.
The user manipulate the
movements of the virtual
environment using the glove.

Motion tracking
 Uses a combination of
computer chips, sensors
and cameras to record
humans in motion.
 Designed for head and
hand tracking in VR games,
simulations, animations, and
visualizations.

Pros of VR
Stimulate real life
situations.
Making learning fun and
interesting.
 Save on cost.
Complex situations
Made easy.
A safe environment’.

Cons on VR
•Expensive equipment.
•Cannot be used by everyone.
•Leads to weight
gain.
•Addiction.

Conclusion
