Virtual Reality is an interface technology that can fool the senses of a user through a virtual environment created from a computer system. By inducing visuals, sound and even tactile effects, virtual reality allows complete immersion in a simulated environment, with or without user interaction
Oculus Rift or Morpheus:. What is the best glasses virtual reality
Currently, virtual reality is based on stereoscopic displays like glasses and headsets, being released mostly for entertainment. But as you’ll see below, the concept encompasses much more than visual effects and it has been around for a long time.
Virtual reality in its most ordinary way, works by stimulating visual and auditory. It is common to use headsets that completely cover eyes and ears, depriving the user to hear and see external stimuli.
Projects like PlayStation VR , Sony promise to completely transport the individual to within a game, with total immersion, both visual and auditory. In this type of virtual reality interface it is possible to look at all sides without having to interact with the control, only turning her head sideways. The Sony headset also includes the option to use headphones for more complete immersion.
History of Virtual Reality
The term virtual reality was first used in the book “Le Théâtre et son double”, the French author Antonin Artaud in 1938. Although not a science fiction author, Antonin practically coined the term to suggest a theater where “natural illusion of characters and objects created a virtual reality.”
Even without the term exists, had already experiments “carried” people elsewhere. The famous stereoscopic glasses with 3D cards sights existed since the 1920s They are the great-grandparents of VR glasses we know today.
In 1939, was introduced to the world in the International Fair New York science the “View-Master”. The device was a stereoscopic glasses that served to see slides in a toothed drive. The device has become a very popular toy. Recently, Google and Mattel announced a new version of the gadget.
virtual reality glasses work?
One of the bases of the visual illusion of a new reality is to forge the current. For this, a simple flat last picture before our eyes is not enough. The same could simply be seen as something false. That’s where one of the virtual reality trumps.
With the use of stereoscopy, the illusion of depth is created, with another immersion element in virtual reality. For this to happen, two different images are generated, one for each eye. The effect consists in the interpretation of the brain that the two images are in fact one.
The technology that first began with pictures, is now used in films and three-dimensional computer-generated environments. Current technologies such as Oculus Rift , allow such a rapid interpolation between images, the 3D effect is stunning.
The highlight of these modern eyewear is the ability to interact in sync with the user’s head movement. Unlike cinema glasses and toys like the “View-Master”. By using the Oculus Rift, e.g., vision is completely overlapped by a 3D display. The image generated does not remain static at a single point, it follows the user’s movements.
Although it is not seen, the great innovation of modern virtual reality devices is on the fast image processing and distortion correction lens. All hidden layers of drivers and software execution in real time.
Virtual Reality today
Nowadays probably 99% of people who hear the term virtual reality, must have heard because of any entertainment product, be it old movies like “The passenger of the Future” or recent applications to games on the Oculus Rift or Samsung Gear VR .
There are already interfaces that allow the gamer to insert completely in a game. Virtualizer of Cyberith is a station where the player can literally feel within a game. Check out the video below demonstrating the technology in conjunction with Oculus Rift.
However, virtual reality can be used in other fields, because the implications for areas such as training are numerous. Since the 1970s, US troops are training exercises in a simulated environment, many of them completely immersed in virtual reality.
Recently, the oil brand Castrol for cars, introduced a bill a three-dimensional environment that is created from a helmet. The pilot runs in a test circuit without seeing the track “real”, trusting only in virtual reality. This in turn creates an entirely different challenge of reality, with other cars and drastic changes on the track.
There are also projects under development linked to the sense of touch. The Level-Up project, for example, allows one to feel the ground you are treading even changing elevation of the same.
