Danger of Virtual Reality In recent years, the development of information technology has created technical and psychological phenomena, which opened to a new quality of human perception and experience as well as has opened a new world - the world of "virtual reality" or "imaginary world of reality". “The term ‘artificial reality’, coined by Myron Krueger, has been in use since the 1970s; however, the origin of the term ‘virtual reality’ can be traced back to the French playwright, poet, actor, and director Antonin Artaud. Virtual reality (VR) is a term that applies to computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds” (http://en.wikipedia.org/wiki/Virtual_reality). Virtual reality (VR) is a computer interface maximizes our natural perception abilities. Although VR is touted as a revolutionary new technology, the idea of inclusion within an artificial environment is not new. In fact VR can be considered an extension of ideas which have been around for some considerable time such as flight simulation and wide screen cinema. Using such systems, the viewer is presented with a screen which takes up a large portion of the visual field giving a powerful sense of presence or ‘being there’. Virtual reality can serve in new product design, helping as an ancillary tool for engineering in manufacturing processes and simulation. Among other examples, the use of 3D printing shows how computer graphic modeling can be applied to create physical parts of real objects used in naval, aerospace, and automotive industries, which can be seen, for example, in the VR laboratory. 3D virtual reality is becoming widely used for urban regeneration and planning and transport projects. This covers remote communication environments which provide virtual presence of users displayed either on a computer screen through the use of standard input devices such as a keyboard and mouse, or through multimodal devices and special stereoscopic displays. However, there are reasons which have raised concern that may be a downside to the exploitation of VR technology. I think that for many people who have followed closely the main issue of VR, have concerns about the dangers of VR technologies. It is really important to know the answers to that issue because we live in the world of new technologies, and we use them in our daily life. There are three main reasons to be careful of the dangers of VR that can be hidden in the surrounding world of technology. The first main reason, the use of VR equipment may have unwanted physical side-effect. Research into the side effects of VR use is a complex and difficult business and it is clear that concerns do remain about the effects of using such systems. Academic research does show that some symptoms occur whilst using VR tools and that these effects (such as nausea) can be quite debilitating in the short term. Whether or not there is a long term effect is difficult to determine, partly due to the fact that VR techniques are relatively new and are constantly evolving. It is also clear that the factors involved in the genesis of symptoms are incredibly complex. Here, there is a complex interaction between the characteristics of the user, the type of system being used and the type of task that is being carried out. Given that there is a large variation between individuals, a huge number of equipment permutations and a vast number of tasks one can see that predicting accurately the effect of any one task in a specific system implementation on a single user is virtually impossible. The physical is important to consider issues involved in the use of VR equipment. In terms of physical issues, more natural interaction techniques may reduce static posture problems; moreover, the use of LCD screens may minimize vision problems....
