The definition of ‘virtual’ means experience near reality as human beings. So, the term virtual reality just merely means ‘near-reality’. Still, it could have meant anything, but it normally refers to a particular type of reality emulation. Everything that we know about reality are linked with our five senses. Put in other words, our entire experience of reality is merely a combination of sensory information and our brain senses.
The meaning of virtual reality exists in the word itself. ‘Virtual’ means almost and ‘reality’ means real, which we human face every day. So ‘virtual reality’ simply means ‘almost real’. "Virtual reality can be defined as a three-dimensional, computer-generated simulation in which one can navigate around, interact with, and be immersed in another environment. Virtual reality provides a reality that mimics our everyday one."
One of the main problems with virtual reality is the health concern. For example, motion sickness. Motion sickness is similar to the people suffering from nausea after spending a period of time in a virtual environment which is due to the effects the shift in perception has on balance. The player may feel dazzling after playing, which is very dangerous if the player plays alone (Virtual Reality Society, 2016). Moreover, the potential health problem of virtual reality is not yet known as VR gaming is just developed for a short period, the testing and research on the field of VR gaming is limited.
In order to underline the different layers of identification I will distinguish between virtual environments and virtual reality. Virtual environments then refer to computer-generated representational spaces of interaction (Hillis, 1999). This also includes role-playing games (RPG) in which players take on characters in fictional settings as well as virtual simulations like Second Life or The Sims. In comparison, virtual reality can be understood as "an interactive and immerse (with the feeling of presence) experience in a simulated (autonomous) world" (Mazuryk & Gervautz, 1996, p. 4) constituted by technology in form of for example head-mounted displays (HMD). Dividing these virtual spaces is necessary to show in how far VR provides a unique case for extending identity beyond the physical body and adds to the creation of multiple
In other words, our entire experience of reality is simply a combination of sensory information and our brains sense-making mechanisms for that information. It stands to reason then, that if you can present your senses with made-up information, your perception of reality would also change in response to it. You would be presented with a version of reality that isn’t really there, but from your perspective it would be perceived as real. Something we would refer to as a virtual reality.” To represent reality, we use linguistics and mathematics. If virtual reality is observed as a communication process between people, mediated by computers, it also can be a communication between a machine and the human.
What is Virtual Reality? • Virtual reality is a completely artificial digital environment that uses computer hardware and software to create the appearance of a real environment to the user. For a user to “enter” a Virtual Reality environment, they must first put on special gloves, earphones, and goggles, all of which receive their input from the computer system as can be seen in the Figure below. • By doing this, at least three of the five senses are controlled by the computer. In addition, the computer monitors the user’s actions.
ABSTRACT - Virtual means not real, where reality can be define as real environment, or we can said that virtual reality is a computer-simulated reality that immerse and presence the user. This is one technology that allow users to feel the object more real. This technology using three-dimensional that simulated physical user presence and allowing them to interact with it. Virtual Reality create sensory experiences such as sight, touch, hearing and the others in order to makes the users immerse and presence between 3D object and the environment. Most of the virtual realities nowadays displayed on the computer screen or used by special equipment that divided by two categories which is fully immersive display and semi immersive display.
