Virtual reality

1. Virtual reality (VR) is an environment of realistic-looking scenes or objects. The more common meaning refers to an environment generated by computer technology, which creates in the user the feeling of being immersed in it. This environment is contemplated by the user through a device known as reality glasses or helmet virtual. This can be accompanied by other devices, such as gloves or suits special, which allow greater interaction with the environment as well as perception of different stimuli that they intensify the sense of reality.

2. Virtual reality is the creation of worlds Interactive 3D by computer, with the intention that the user appears to be immersed in another reality. To do this, normally, wear glasses that have a screen for each eye, thus creating the feeling of being in a 3D world around you everywhere. We will see how this has evolved discipline.

   • -Beginning (60s): Not much after the first color television broadcasts, began to patent the first machines and helmets of virtual reality. They were not interactive, due to the impossibility at that time of generate 3D graphics by computer in real time, but included other features curious
   • 70s: A series of algorithmic advances in graphic computing during this time made possible that the following generations of gadgets could show 3D graphics interactive and more realistic.
   • - 80s: As I have already said, in the 70's algorithms are developed to display 3D graphics by computer, but until the 80s these graphics cannot be generated in real time, since until that At the moment the computers did not have enough power to generate them.
   • - 90s: 1991: Antonio Medina, designs a virtual reality system to drive the Mars robots from Earth, apparently in time real, despite substantial delay of the signals between the two planets 1995: Nintendo presents in Japan and the US a console called Virtual Boy. With her they could see 3D monochrome games. Was a great failure, that's why he retired in nineteen ninety six.
   • - Today: Virtual reality today has many applications. Can be used as interface to interact with the system operating, control a robotic arm through distance, play, flight simulators, etc. But these technologies are currently too expensive and uncomfortable for the user. The most interesting that I have seen on the net are the iWear VR920 glasses, as they incorporate head tracking. These glasses have some problems, for example, cost $ 400, head tracking is incorporated by few games and 3D does not work with some graphics cards.

3. We speak exemplifying the Extended Reality (Reality Extended) is a conjunction of each of the realities, VR (Virtual Reality) + AR (Augmented Reality) + MR (Mixed Reality). VR It is not a new technology, it works with her since 1968, even though her democratization It is not until 2013 with the origin of the Oculus Rift DK1. AR It is based on an overlay of the content made by a computer on the real planet; I mean, with the truth augmented virtual content is produced and inserted into the real planet. MR Engineers have the ability to view in real time and immersively various variants of a car, finishes, materials, colors as well as the handling from a first virtual model, as if it were in front of the real product however without the need to physically manufacture it. In short, the reality virtual is a suitable instrument for design equipment, suppliers and consumers end

4. Types of reality virtual

   • Semi-immersive virtual reality
     • Semi-immersive virtual reality offers users a combination of real and virtual interactive elements. A example is 4D cinema, but the most common application is training, for example, with flight simulators that they have a realistic cockpit that moves. This type of applications allow you to train professionals without risks physical, nor high bills in case of error.
   • Reality augmented
     • Augmented reality, or AR, mix virtual elements with real items. While the pure virtual reality creates a environment that is not real, and everything is based on this environment, the reality augmented yes that is based on our real environment, but what expands, modifies and complements.
   • Collaborative virtual reality
     • This form of virtual reality projects the same virtual environment for several users at the time, regardless of your location, to share ideas and work together on projects. Can be as simple as a conference room virtual, for example.
   • RV in the manufacturing
     • It is one of the forms of VR with greater development capacity. The RV and RA can ensure safety and quality in every step of the manufacturing, from design to inventory management.
   • Medical VR
     • Without a doubt, one of the VR manifestations most promising, as it allows simulations very immersive and faithful to the reality of processes surgical procedures, and thus allow risk-free training to surgeons.
   • RV therapy
     • There are patients with phobia or disorders related that can benefit from gradual exposure to source of the problem, a process called systematic desensitization or therapy of exposition. Virtual reality allows these patients to undergo to exposure therapy in a controllable, secure and private environment, which increases the effectiveness of the treatment.
   • Virtual reality mixed
     • This technology allows combining virtual reality with the physical world offering an experience unique and very realistic. It is not the same as Augmented Reality, which provides information superimposed on what we perceive, but here it is they overlap two worlds: the real and the virtual.

5. The main areas of reality app augmented are: * Architecture and urban design * Digital Marketing * Education and training * Engineering and robotics * Entertainment * Health care * Safety Occupational * Social Sciences and psychology
