Virtual Reality: Enter A 3D Man-Made World : Virtual Reality (VR) is defined as a three-dimensional artificial environment wholly created by optics and special software to make the user experience a man-made interactive world. In order for VR to work, the user must wear a special headgear and other virtual reality peripherals, like gloves and controllers, in order to “interact” with the VR world.

Four Vital Requirements Of Virtual Reality
There are four vital requirements for a virtual reality environment to “exist”: the virtual world itself, immersion, sensory feedback, and interactivity.
1. The Virtual World
The Virtual World
This is the world created by the special software specifically designed to “draw” life-like objects inspired by real-world in our surroundings. This virtual world can be anything the programmer wants – even dream-like or non-existent worlds can be created in virtual reality. This is the environment where the virtual traveler will go in three dimension using the proper equipment.
Immersion is the sense of being physically “living” in the virtual (non-existent) world. For immersion to be perfect, the user must completely forget that he is moving in a virtual world. The user must have a perception of reality of the virtual world while forgetting the true existing world.
So far, totally immersion has not yet been achieved by any combination of the presently existing equipment and software. Developers are extremely close to delivering that total immersive experience in the near future.
3. Sensory Feedback
In the real world, we use our five senses (sight, smell, taste, touch, and hearing) to experience our surroundings. Scientists and developers are striving to achieve the same effect in the virtual world. Right now, only three of our five senses have been employed by developers to achieve sensory feedback in the virtual world.
Visual inputs are the easiest to achieve as the user must “see” the virtual world he is entering. Visual feedback should enable the user to see his virtual world in full 360 degrees. Haptic (touch) feedback is the next important element in the virtual world as users’ need to “feel” his man-made 3D environment. He should be able to manipulate anything in the virtual world like it was existing the true world.
Aural (hearing) feedback should be so realistic that the user should experience sound as it “moves”. For instance, the sound of a virtual train should become louder as it approaches the user and consequently become soften as the virtual train leaves the user behind.
The final element to complete the virtual experience is interactivity. Interactivity encompasses all the things a user can do in the real world: flicking a switch to open the light, holding a ball in his hands and be able to manipulate it any way he pleases or change position in his virtual space as if he is really moving.
Today, big companies like Samsung and Oculus VR are developing their own proprietary virtual technology gear and software. These companies know that the future of virtual reality is big. Statistics show that people are interested in virtual reality.

Applications of Virtual Reality
Presently, virtual reality is mostly used in gaming and movies. The niche for this market is continually growing. Virtual reality is also used today in all aspects of our lives. From training new pilots to operating on virtual patients, virtual reality is used because it is much cheaper and safer.
With the technology at the disposal of our scientists and programmers today, virtual reality is becoming the next big thing that everyone is trying to perfect. The first developers to deliver this will surely become billionaires as more and more people want to own their own virtual world.
