Virtual Reality refers to a
high-end user interface that
involves real-time simulation
and the interactions through
multiple sensorial channels.

 In 1950s, flight simulators were built by US Air
Force to train student pilots.
 In 1965, a research program for computer graphics
called “The Ultimate Display” was laid out.
 In 1988, commercial development of VR began.
 In 1991, first commercial entertainment VR system

n Every headset aims to perfect their approach to creating an
immersive 3D environment.
 Each VR headset puts up a screen in front of eyes thus,
eliminating any interaction with the real world.
 Two autofocus lenses are generally placed between the s
creen and eyes that can adjust based on individual eye mo
vement and positioning.
 The visuals on the screen are rendered either by using a mobil
e phone or HDMI cable connected to a PC.
