Simulation of the real world – Virtual Reality:
It is difficult to state with certainty about the people involved in developing this technology system .But if we discuss about the realm of virtual experience,the person Morton Heilig is the one who produced first interactive 3D film.
IVAN SUTHERLAND first created head mount display HMD(head mount display) which was attached to the computer.It was not comfortable to wear and and closely resemble like portable tv.

Virtual reality -VR typically refers to technologies that use virtual reality headsets which are used to generate the realistic images, sounds and other sensations that replicate a real environment or establish an imaginary setting. VR also simulates a user’s physical presence in this environment.It makes us to visualize artificial environment through the sensor stimuli.

The first way VR does this is with the stereoscopic display.VR can include 4 of the 5 senses, including vision, hearing, touch and possibly even smell too.The way the stereoscopic screen looks varies platform to platform as each headset differs quite a bit in the way it display content.

The lens makes the moving to dimensional object look like the real world 3D.But the cool part is no need to download separate app,can access just direct from YouTube.Youtube directly supports the VR content.tThe video moves with motion of the phone.
Main problem experiencing with it is the availability of hardware and price which is not affordable.

VR is applied in many fields like in Education ,telecommunications,military ,,health care ,Entertainment,fashion ,Film ,construction , sports ,media, gaming videos etc.
