4. Definition of VRDefinition of VR
Virtual reality is an artificial
environment that is created with software and
presented to the user in such a way that the
user suspends belief and accepts it as a real
environment.
SOFTWARES :-
Popular products for creating virtual reality
effects on personal computers include Bryce,
Extreme 3D, Ray Dream Studio, trueSpace, 3D
Studio MAX, and Visual Reality.

7.  In mid 1950s visionary cinematographer
Morton Heilig built a single user console
called Sensorama that included a
stereoscopic display, fans, or emitters, stereo
speakers and a moving chair.
 This enabled the user watch television in three
dimensional ways.
 In 1961, Philco Corporation engineers
developed the first HMD known as
the Headsight.

8.  The helmet consisted of a video screen
along with a tracking system.Then they
linked to a closed circuit camera system.
 Then somewhat similar HMD was used
for helicopter pilots. While flying in the
dark these were of great help –
NightVision

9.  In 1965, a computer scientist named Ivan
Sutherland revised HMD to
“Ultimate Display.”
 After using this display a person imagines
the virtual world very similar to the real
world.

Man, Don’t I look cool!
