What is virtual reality and how does it work?

Virtual reality is all about the computer-generated environment with the software and it presents to the users in such a way that users believe it as a real environment. Virtual reality is experienced through sight and sound through the computer. It is also a three-dimensional effect in which the computerized program looks real. This virtual reality in the 3D image can be experienced in a personal computer. Usually by manipulating keys or by using the mouse the content of the image moves in some direction or zoom in or zoom out.

Everything we know about reality made by our senses. If you can present your senses with made up information our perception of information may also change according to the response to it. We can be presented with the version of reality that is there but in our perception, it would be real but it can also be virtual reality. Virtual reality uses a host of technologies to achieve their goal and it is technically complex that has to account for our perception and cognition. It has both entertainment and serious issues. This technology is becoming cheaper and it is spreading widely very fast. We can expect more innovation in the future in the three-dimensional technology.

How does it work?

Today the virtual reality is implemented by the computer technology. There are many varieties of systems that are used for this purpose they are like headsets, directional thread mills, and special gloves. These are used to stimulate our senses together in order to create the illusion of reality.

It is more difficult than it is said. As senses and brain provide us with the well systematic experience, if anything is little different we can guess that and tell. The issues that divide convincing or enjoyable virtual reality experience are partly technical and partly conceptual. If the implementation of virtual reality manages to get the combination of hardware, software, and sensory synchronicity then it achieves something known as the sense of presence. Where the subject really feels like it is present in the real environment.

There are many varieties of application for virtual reality like

• Architecture
• Medicine
• Sports
• Entertainment and

Whenever if it too expensive or dangerous or impractical to do something I the reality, virtual reality does the experience which can’t be done in the reality. From a fighter pilot trainee to medical representative trainee or surgeons, virtual reality gives them to take virtual risks in order to gain real-world experience. As the cost of virtual reality goes down and it becomes like a mainstream and you can expect many more serious and advanced uses of it, such as education or productivity applications, to come to the forth, virtual reality and its augmented reality could substantively change the way they interface with our digital technology and continuing the humanising our technology.
