Meaning that our entire experience of reality or real world is simply a combinatin of sensory information and the sense-mechanism of our brain for that information. Now we can say then, that if you can present your senses with some fabricated information, your perception of reality would also change in response to it, which means you will be presented with a version of reality that's not really there, but something from your fabricated perspective, that will be perceived as real.
This is what can simply be termed as virtual Reality, that is, presenting our senses with a computer generated virtual environment that we can explore in some ways. So basically that is the no technical definition of VR.
We can also define virtual reality in more technical terms as a three-dimensional, computer generated environment which can be explored and interacted with by a person, who becomes immersed withing this very envirnoment and aslo be able to perform a series of actions or manipulate object in that virtual environment.
There are systems that can be used to stimulate our senses together in order to create the illusion of reality, systems like a headsets, Special gloves and some goggles. One may even ask, what's the need for virtual reality? well the entertainment value of this innovation is enermous.
Here, immersive movies and video games are very good examples, but there are other more powerful applications that can use virtual reality in achieving great fits.
We can see for example, that wherever experiments or things are too dangerous or too expensive to do in reality, virtual reality can be the answere here, like trainee Surgeons, trainee fighter pilots and others can be simulated in the VR, meaning we take virtual risks to gain real world experience. This like i wrote in the first article can change the way we interface with our digital technologies.
