What is Virtual Reality?

Virtual reality is a computer technology that uses software and hardware to make realistic sounds, images that almost resemble the environmental object or create an imaginary setting.

It can as well be defined as a realistic and immersive simulation of a three-dimensional environment, that is made using an interactive software and hardware, and it is being controlled by body movement.

For example it can make you think that you’re sitting in a roller costar while you are sitting in your couch at your home.

Major Players 

The likes of the HTC Vive and Oculus Rift provide PC-based operations.

Though major players such as Google  and Samsung offer more affordable, smartphone-based headsets.

Google Cardboard is like the most basic VR product possible which enabled anyone with a smartphone to start playing/developing. Developers, techies and big children started buying these and exploring a new world.

Google Cardboard is also an app for Android and iOS. It has a video player which links to YouTube, which now supports 360 and VR video.

Sony have also come up with its Playstation VR.

How Virtual Reality devices  works ?

You can use the VR headset to place your Smartphone’s display in front of your face.

The goal of the hardware is to create what appears to be a life size, 3D virtual environment without the boundaries unlike we usually associate with TV or computer screens. So whatever way you look, the screen mounted to your face follows you.

Image is sent from Smartphone slotted into the VR headset to the

virtual reality glasses  that contain polarized lenses which shows two images of the same image, one per each eye. These images appear to give an illusion of depth which is a particular feature of Automatic Virtual Environment

The image is divided into two parts so that each eye views the same thing creating a real world 3D feeling to the user. This process gives an experience of getting immersed in the real world due to a very close view of videos.

There are a few different internal components which can be used in a head-tracking system, such as a gyroscope, accelerometer and a magnetometer.

 

Are you looking this video on your PC then wait and load this video on your smartphone and the difference you will see something like this.

Uses of Virtual Reality:

Virtual reality enables the user to look around the artificial world and interact with features they see on the screen of the VR headset. Touch, sight, and hearing are sensory features that can be created by virtual reality. Projector screens, computers, and virtual reality headsets are some of the machines that display a virtual reality.

Educational Uses:

In learning, instructors use virtual realities to provide the learners with a virtual environment where they can develop their skills without really feeling the impact of the real world failing. Virtual reality helps the students taking complicated courses such as piloting, surgery as well as military students to do practical without really facing it in the real world.

Entertainment Uses:

Entertainment uses virtual reality, for example, the virtual reality games such as Virtual Boy, Play Station that is made by the incorporation of graphics, sounds and input technology. Most companies currently struggle in making of the virtual reality headsets that will produce a super quality sound to enhance the game playing as well as music and movie watching.

Environmental Uses:

In 2010, urban regeneration, transportation as well as planning projects were using virtual reality to perform such actions. Development of a software for use by land surveyors and civil engineers by the use of virtual reality improved performance in these fields.

A number of roller coasters have been fitted with virtual reality for example Galactica at ALTON Towers, The New Revolution at Six Flags Magic Mountain and Alpenexpress at Europapark are just but a few examples of roller coasters fitted with virtual reality.

Conclution:-

Virtual reality has been used as a training tool in most of the institutions because of its advantages such as no risk incurred, it very safe, brings realistic scenarios, it improves concept retention as well as the recalling of the learned ideas, makes complex problems become very simple among other advantages.

The advantages of virtual realities overwhelm its disadvantages, means VR is more important and useful tool when purchased and being used by any institution.
