However, in the 1985 ‘virtual reality’ word was became spread to the public widely.Īfter this, in the late 1980s and late 1990s, the public’s attention in virtual reality technology was extremely high. A year later, when the NASA began its Apollo project, virtual reality technology developed fast and it used as a computer interaction reaction system to train its crew in 1969. University of Utah’s Ivan Sunderland studied of head mounted displays (HMD). The world’s first virtual reality original technology source was beginning in 1968 where U.S. In this book includes a direct depiction of holographic technology, virtual realization of touch and smell. The book was written in 1935 by American science fiction writer Stanley G. And, the more advanced virtual reality concept was introduced from the ‘Pygmalion’s Spectacles’. In literature, we can find similar concept of virtual reality in the ‘Brave New World’, an SF dystopian novel published by Aldous Huxley in 1932, something like as ‘haptic technology screen’. That is an origin of 3D display technology today. The first prototype of virtual reality was developed in 1852, it was called a “stereoscope”. The concept of virtual reality dates back to the 19th century. Virtual also means ‘substantially effective’ or ‘false.’ It also means “a reality has no substance but, that provides an experience to user that can be sensed practically by a illusion.” In this interpretation, “virtual reality” is not a strange word. This is “real world” (reality) because it is felt through the senses, not the user’s illusion. Although, the substance is a faked world, but on the one hand it is clearly visible and heard, and as technology advances it may be felt by our senses. Consider the fact that ‘virtual reality’ is a virtual world that allows you to see, hear and feel. However, from a different perspective, it is a convincing term. Considering on this point, some people use that concept as a ‘virtual world’. Putting them together, it becomes ‘a real world that is not real but has been built in a false sense’, and a ‘real world that does not exist but exists’ by if we removed the intermediate modifier. However, ‘virtual’ means ‘things that are not real but falsely built’. ‘Reality’ means ‘a real (looks like) world in which an object actually exists, or a phenomenon unfolds’. When you investigate the word ‘virtual reality’, you can see a somewhat unique meaning. Virtual reality can distinguish between “real” and “virtual,” but there is a difference that simulated reality is so realistic that makes impossible to distinguish what is real or virtual. The sub-concept is ‘Simulated Reality’, which is a simulation of virtual reality as close as possible to reality. However, generally speaking, virtual reality means technology that enables spatial and temporal experiences close to reality by directly acting on the five senses of the user, beyond simply implementing a virtual space. The basic concept of virtual reality means ‘an artificial environment similar to reality but not real.’ Therefore, in a broad sense, visual media such as games such as simulator games and second life can also be included in virtual reality.
