Hey Mi Fans,

In Previous Tech Class thread you all are aware about QR Codes
Today's Tech Class is all about Virtual Reality (VR)

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. So the term ‘virtual reality’ basically means ‘near-reality’.
Technicaly Virtual Reality is the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.

How does Virtual Reality Works?

Virtual Realty glasses or goggles are becoming increasingly popular in the gaming and entertainment spheres. They are lighter and more comfortable to wear than the standard head mounted display (HMD) and many of them incorporate a range of interactive devices.

These glasses behave in a similar way to a pair of 3D goggles in that they display two images. Ordinary glasses show a single image but 3D and virtual reality glasses contain polarised lenses which show two images, one per each eye. These images appear to give an illusion of depth which is a particular feature of CAVE  environments

More advanced versions of these glasses contain head tracking systems. This system is connected to a computer which sends signals to adjust the images seen by the wearer as they move around their environment. Once again, this is a particular aspect of CAVE Fully immersive  virtual reality

These glasses enable the wearer to see three dimensional images which give an illusion of depth of perception. For example, if the wearer is using virtual reality for architectural purposes then they will be able to view a building at different angles, and walk through or around it.

Many types of glasses contain a tracking system which maps the wearer’s movements and adjusts the images accordingly. Each time the wearer moves his head, walks in a particular direction or takes some other form of action, the scene in front of him changes as he does so.

The tracking system is connected to a computer which adjusts these images so that the wearer is shown a realistic environment with a realistic depth of perception. The tracking needs to be as accurate as it can be or else the illusion breaks down.
The glasses enable the wearer to see two separate images which the brain combines into one. This is what gives the illusion of 3D depth. This is often accompanied by video and/or sound which add to the experience.

The aim is to present the wearer with a world which is realistic and behaves in a similar way to the real world.

History of Virtula Reality
The history of virtual reality start from 1939, When A stereoscopic visual simulator was introduced, Then Development of Virtual Reality happens,

1. View- Master a stereoscopic visual simulator, was introduced in 1939.
2. The Sensorama was released in the 1950s
3. Battelezone, an arcade video game from 1980, used 3D vector graphics to immerse the player in a VR world.(Atari).
4. A VPL Research DataSuit, a full-body outfit with sensors for measuring the movement of arms, legs, and trunk. Developed circa 1989. Displayed at the Nissho Iwai showroom in Tokyo
5. The affordable and accessible Google Cardboard standard in 2010
6. A 2013 developer version of Oculus Rift from Oculus VR.

Technology Of Virtual Reality
Virtual Reality Connected with human , Hardware and software . All three things work for imagine the 3D.


So the term ‘virtual reality’ basically means ‘near-reality’.
Near reality means, suppose a game is playing  in a device , if you put it on VR and Wear it, You can feel that you play the game in reality!
And VR Works like our Eye! All know how our eye work,
"We have two eye, we can see the nature in 3D, But Our Mobile Screen is 2D, So In VR There Are two glasses like our eyes and With it we can see mobile screen in 3D."
