Virtual reality is coming to a close




by Christophe » 14/06/15, 20:57

Virtual reality, invented more than 30 years ago, is now back with great strides for the general public ... This thanks to the evolution of smartphones which have greatly reduced prices and miniaturized "HD" screens, graphics chips and motion detection components (accelerometers, gyroscopes ...)

History on wiki: http://fr.wikipedia.org/wiki/R%C3%A9ali ... _virtuelle

Free applications for the general public are already numerous: small simulators or 3D games, demos of technology, 360 ° video or even films ... just type "Cardboard" or "Virtual Reality" in Google Play or the Apple Store ... and there are certainly "eco-friendly" applications ...

Your shop forum favorite offers 2 headsets at low prices to discover virtual reality with a smartphone: https://www.econologie.com/shop/realite-virtuelle-c-98 (the quality depends on the smartphone used, it is equivalent, if not better than an oculus that I could test)

To test because it's really nice ... the most impressive is surely the 360 ​​° videos (in fact 360 ° in the 2 axes) but they are rather heavy: count 100 Mo / minutes.

You need 6 wide angle cameras (Gopro style) to make a 360 ° video!

Not to be confused with augmented reality, it's trivial, but I prefer to specify it: http://fr.wikipedia.org/wiki/R%C3%A9ali ... ent%C3%A9e

Here is a site that offers 360 ° videos: http://www.360heros.com/

We can read them directly on PC and move with the mouse (but the effect is much less interesting than in immersion with headphones).

Example of a video with a pendulum ULM: http://video.360heros.com/website/users ... php?vid=54

Attention the loading can be long, as I told you above, the 360 ​​° videos are, inevitably, quite heavy in terms of bit rate!

When will total immersion as in Total recall ou Matrix?

Soon Sen, soon! Google will do it before 2040 I think ...

But let's give Caesar what belongs to him: the first film to talk about total immersion is good Brainstorm in 1983, an excellent film of anticipation which had interested me well when I saw it at the time (I think beginning of the 90 or end of the 80).

I saw him again 2 or 3 years ago: he unfortunately has aged quite a bit (not in the concept but in the way of filming ...) and might deserve a remake (better than that of total recall which is a stew monstrous I think ...)

Small econological note: the main actor (I believe) uses a recumbent bike and we see a kind of earthship ecoconstruction-hqe / earthship-the-housing-recycle-green-and-ecolo de 40-year-t9821.html (green house)

Not too soon I hope, because in a world in crisis many could choose to stay permanently connected ...

But who tells you that we are not already connected? : Mrgreen:

Another great film, but as little known as Brainstorm, is Virtual past... which I highly recommend but which was ousted by Maxtrix at the time (well it was not the same budget and it has some faults but it made me, finally, more thinking than Matrix ...)

Imagine that this is a question taken seriously:

Do we live in a computer simulation created by our descendants?

As wacky as it may seem, American and German physicists have proposed a methodology capable of testing whether the reality in which we live is a computer simulation created by our descendants.

Are we living in a computer simulation created by our descendants? If this idea, launched ten years ago by Nick Bostrom, professor. of philosophy at the University of Oxford (read his article "Are you living in a computer simulation?" published in 2003 in the journal Philosophical Quarterly), is undoubtedly stimulating for the mind as evidenced by the success of Matrix, however, its probability legitimately appears to most of us to be very low. Yet, we have to admit ... that we have no proof to say that we do not live in a virtual universe created by future generations.


http://www.journaldelascience.fr/physique/articles/vivons-nous-dans-une-simulation-informatique-2867


And even more serious:
The world is a quantum computer

physique - by Pablo Arrighi AND Jonathan Grattage in monthly n ° 467 dated September 2012 on page 72 (2119 words) | Free

Can our Universe be represented as a very large parallel computer? No doubt, provided that this computer obeys the laws of quantum physics.

Yet a number of internationally recognized physicists, including Seth Lloyd of the Massachusetts Institute of Technology in the United States and Lee Smolin of the Perimeter Institute in Canada have recently taken up the subject. They support the idea that research in theoretical physics should focus on the notion of "information" and not on that of "matter". According to them, it is necessary to go beyond a vision of the world in which particles propagate and interact, and to emphasize concepts such as entropy (a function of measuring information) and the exchanges of between systems.

It makes you think!

Super thank you for these more scientific than filmographic articles.

In fact "a computer simulation created by our descendants" is quite the theme of the film Virtual Pass (which came out a little before these studies!) ..

Well, almost: I don't want to break the suspense for those who haven't seen it yet! There is still a "level" above :)

Google has just released the Cardboard Camera application which allows you to take 360 ​​° photos in less than a minute with a smartphone: https://www.econologie.com/shop/blog/goo ... ilement-n9

To be tested therefore, even if you do not have a virtual reality headset: a "panoramic" version is also created with each image!

So if you are lacking an expensive Christmas gift idea with a wide variety of applications, consider taking a look here: https://www.econologie.com/shop/google-c ... p-607.html
