In general sense, virtual means near and reality is what we experience as human beings. But technically speaking, the term virtual reality is used to describe a three-dimensional, computer-generated environment, which a person can explore and interact with. That person immersed within this context or becomes part of this virtual world can manipulate objects or also can perform a series of actions.
In today’s time, virtual reality is usually implemented using computer technology. There is a range of systems that are used for this motto, like headsets, special gloves, and omnidirectional treadmills. These all are used to stimulate our senses combinedly to create the illusion of reality.
This is more difficult than it sounds, as brain and our senses are evolved to provide us with a well synchronised and mediated experience. If anything is even a little bit off, we can usually tell. This is where you’ll listen terms such as captivating and realism enter the conversation. The issues that divide enjoyable virtual reality experiences from unpleasant ones are partly technical and partly conceptual. Virtual reality technology needs to take human physiology into account. For instance, the human visual field does not look like a video frame. We have around 180 degrees of vision, and we are not always consciously aware of our peripheral view, if it were gone, we had notice. Similarly when what our eyes and the vestibular system in our ears tell we conflict it can cause motion sickness. Which is what happens to some people on boats or when they read in a car.
If the implementation of virtual reality manages the combination of hardware, software and sensory synchronicity just right, it achieves the sense of presence.
Why is it essential to have virtual reality?
Architecture or sport, medicine, art or entertainment…, and much more spheres like this where the wide variety of applications for virtual reality is used. It looks like a lot of effort, and yes, it is! The potential entertainment value of virtual reality is apparent. Video games and immersive films are good examples of it.
Virtual reality can lead to new and exciting discoveries in the areas which impact our regular lives. The things which are expensive, dangerous, or next to impossible to do, virtual reality is the answer to all of these things. Through virtual reality, one can take virtual risks to gain real experience. With its decreasing cost, it becomes more mainstream, and we can see the better use of it in education or other productive applications. It will change the way we interface with digital technologies.
Virtual reality is the creation of a virtual environment presented to our senses, and it is shown in such a way that we treat it as real experience. It is used for entertainment as well as for the betterment purposes. The technology is getting cheaper and more widespread. WE are yet to see many more innovative uses for the technology in the coming future.
