Put on VR glasses and dive into other worlds: What was previously only known from individual computer games is increasingly permeating our entire society. Will the boundary between the real and virtual worlds soon disappear? Looking at the steadily growing success of Virtual Reality, this impression does not seem entirely unfounded. In the following, we will introduce you to the new technologies in a little more detail.Short definition: This is Virtual Reality!Virtual Reality (VR) is a computer-generated reality that consists of a three-dimensional image and is often supported by sound, movement and sometimes even smell in its mode of action. The transmission usually takes place via large screens, in specially prepared rooms or via a so-called head-mounted display, also known as VR glasses.
How are virtual worlds created?A virtual world can be created either with a real camera or with computer technology. On the PC, so-called vectorized 3D environments with objects and figures projected into them are created on the basis of certain algorithms. The possibilities of virtual reality are becoming more and more complex with the constantly improving digital technology and thus also offer many companies completely new possibilities to stage their goods.Sense and purpose of virtual realityVirtual reality originally had a military background and is still used today for training soldiers. However, virtual worlds have also long since found their way into the everyday working world.
For example, flight simulators are used to prepare flight students for dangerous situations. A flight simulator not only works with a very real virtual image of a flight route, but also acoustic signals and even movements of the simulated aircraft are part of the program. The entire training session must be as realistic as possible so that the pilot-to-be knows exactly what to do to protect the passengers and crew in a critical situation later on.Virtual Reality also means completely new horizons of experience for science and research. Real scenarios can be designed on the computer down to the smallest detail and enable scientists to gain comparably good insights as very real test situations.
With one important difference: life and limb are not endangered in virtual worlds.Critical opinions on the new digital technologyAlthough virtual worlds may sound great at first, computer technology is of course not without its drawbacks. Although it is possible to play out certain situations or recreate dedicated scenarios, errors in the environmental variables cannot be ruled out. Algorithms work purely logically; human feelings and irrational behaviour are, at least for the time being, alien to them. Another critical point is the danger of addiction that VR computer games in particular possess.
Young people in particular tend to make excessive use of virtual worlds and thus find it increasingly difficult to connect in real life. Even the computer-generated worlds are still not really perfectly implemented. The fast representation necessary for the simulation of reality is still in its infancy. But the development is progressing steadily, in a few years the handling of virtual reality will have become quite commonplace for all of us.
