The Virtual Reality

The virtual reality is a dream everyone hoped for years: the only fact to connect a device on your head in order to evolve in some different worlds might change our habits for a long time. Indeed, the digital world has been continuing its sciences progress and it will still continue. Even if it’s still young, virtual reality might be a new evolution in several forms of work and hobbies. That’s why we will drop an eye on its most important aspects.

First of all, there is not a unique definition of Virtual Reality because this concept applies to many domains. However, there are two huge aspects that includes Virtual Reality. Virtual Reality is a simulation creation based on cognitive sensations to immerge the spectator in a world which looks like to reality itself or in a whole imaginative dimension. This immersion is possible due to two main technologies. The first one consists to put the spectator in a room composed of several projective screens. These screens will show images for the spectator. To make it immersive, camera will fix the spectator and save its position due to captors attach to him. If the spectator moves the head, the images on the screen will be real-time calculated in order to follow the spectator’s vision. The second technical issue is recent and could be the most used application of virtual reality : it consists in a headset which contains a stereoscopic screen. The eyes of the spectator are constantly stalked one by one by the screen’s captors : if you move the head while wearing one of these, the hardware will calculate your eyes position in order to adapt the image to the head’s position.

Due to its immersion potential, Virtual Reality has now the tools to be an economic actor. Indeed, some corporations already specialized in this domain in order to provide goods and services. First of all, if you look at the hype gartner cycle released in July 2014, Virtual Reality is located just between the trough of disillusionment and the slope of enlightenment. Today, Virtual Reality is not incremented on many domains despite its progress. That’s why it is still considered as something quite marginal, but it might take weight as soon as the population will have access to it. However, virtual reality is nowadays used in some ways that link dangerous real situations and experts training. For example, it could be used during a parachute training : the data are both sent and received by an operator whom controlled the situation. This technical device can simulate different weather conditions, a parachute malfunctions and other kind of problems the Army would have to face in real time. Secondly, the virtual reality technology may apply to the industrial maintenance of a nuclear reactor. This is today’s main target of professional virtual reality : the telerobotics. Indeed, some situations training require technical tools due to their dangerous nature. It is the same case for the E-health development, especially to learn to control robots during complex chirurgical operations.

Due to its large domain of application, virtual reality could really become another way to discover, to play, to watch a movie or whatever. A spectator would be able to walk and could look at some paintings on a museum located far away from him. However, some areas are nowadays directly impacted by this technology. Indeed, video games currently tend to be compatible to this technology in order to provide the best experience for the gamer. That’s why the “Oculus Rift” project encountered a huge success : even if the virtual reality’s economy is still immature, some big corporations tend to find an interest in this technology. Finally, virtual reality doesn’t look as wonderful as it might. Indeed, there are still some questions concerning health issues linked to the fact we are situated in another reality. There is a big difference between the reality created by a stereoscopic screen and the reality itself : if the images ceased to be synchronized for a short moment, the inner ear might cause to the user some nauseas or headaches.

To conclude, we can’t explain each domain that virtual reality could include in the future. Moreover, Facebook bought the Oculus rift project, a virtual reality headset : social medias users might possibly discover some new interactive ways to communicate or to like others status, instead you don’t want to look a cybernetic human being wearing a technological headset in the street.
