The hi-tech companies are betting that there will change his life. But that extra-reality model manages to establish itself?

#Virtualreality.

With a head-up display, we can immerse ourselves in virtual worlds projected stereoscopic display on the two places at eye level. Processors and specialized software generate an environment in which we can move, exploring it 360 degrees and deep, offering an experience that, at best, we perceive as real. motion sensors manage our actions in this environment, #3Dsound increases the feeling of immersion and a controller to hold allows us to interact with objects. The key word is “presence”: when the VR technology is managed in the best, manages to trick the brain to the point that you can find yourself in front of a tyrannosaurus “fake”, and retreat in fear.

This is precisely the challenge of VR, which affirm itself needs to improve on some fronts, otherwise it is likely to remain firm to simple video to move with the mouse freccina on Facebook and YouTube (such as the video above). The first is the latency, ie the time that passes between the movement of our head and the virtual environment adaptation: in addition to break the illusion and give the sensation of “falsehoods” to the brain, high latency due to the so-called motion sickness, a kind of seasickness.
The second front, connected to the first, is that of the media: the helmets are heavy and totally insulating means that can not be taken for a long time and that, by disconnecting sight and hearing from the physical world, expose us to risks. In addition there is the cable barrier, playing against the freedom of movement. The third key aspect is that of content: are totally invented, or rather imagined.
Meanwhile it is spreading a VR lower, simpler. He is carrying on with its Google Cardboard, a small carton of $ 20 viewer (but you can also build it yourself or assemble it with about 3 euro) in which to insert a smartphone to view images 360 degrees with a degree of basilar immersion. It seemed like a joke, but when the New York Times, has sent 1.3 million to his readers to be able to see 360 ° its news reports via app (in the video below, in English, an example), others have followed ‘example, pushing the spread of this VR less pretentious.
