Lei feng's network (search for "Lei feng's network", public interest) Editor's Note: do you want to know about Facebook vision for the next decade? VR vertical media VRerse (code), founder of Nada wrote about (very detailed) ~
For technology companies, attention CEO CTO than concern sometimes get dry. Facebook F8 Conference on the second day of this year, the opening is the CTO of Facebook and the Oculus company's chief scientist. The two of them together tells us Facebook wants to achieve over the next ten years.
First vision of Facebook introduced Facebook CTO Mike Schroepfer. As the world's largest social networking platform, in the next decade, Facebook hopes to become a closer connection and channel relationships between people. But how are they going to do? There are three problems need to be solved.
First: Facebook needs to build a global infrastructure systems to connect the whole world, covering those areas with no Internet.
Secondly, Facebook needs to develop a natural way to deal with the growing clutter of information, guarantee not to be overwhelmed by information.
Third: Facebook needs to create virtual reality, to make people and myself who are willing to place the experience they want.
Why Facebook wants to solve these three problems to achieve its purposes? Mike to the history of changes for example: infrastructure is the way information transfer – from wagon to the train to the telegraph to the telephone, and all these things is to convey information, means of connecting human, for the problems, efficiency is most important. However, the phone, the first time humans have a natural way of interaction, people can call each other in tone to determine sentiment, further communication at this level, emphasis on design, how to design to strengthen communication between man and man, of great importance. Virtual reality is the end of all this, as the Exchange is just and your Exchange objects in a certain space of a specific experience.
This is Facebook's main task for the next decade, then, they should now do what?
This is Facebook set up four centres for open computing projects, structures, components are designed and manufactured by Facebook engineer, General design compared to its efficiency, for one year only at the hardware level is for Facebook to save $ 2 billion. The project four years ago, are all open source, praised by industry, anyone can design according to your needs referencing Facebook to set up their own service center.
Hardware alone isn't enough, software level, Facebook has high performance PHP virtual machine HHVM, also has a source, Mike also announced that front-end React Native open source.
In terms of networking, roughly 1.1 billion to 2.8 billion people now live in outside of network coverage. In the context of the base station cannot be laid because the accounts does not come from any level, in areas with low population densities to create mass base station is wasteful and environmentally unfriendly. Do we have a way to reduce costs?
Facebook's answer is unmanned.
These UAVs for the Solar Wing, wings more than a Boeing 737, but the quality is only one car will fly at an altitude of 18 km-27 km, took off the air for three months at a time, in order to bring mobile network coverage in remote areas. Facebook will disclose more information about the second half of this year, and this is their response to Google Fibre and balloons.
This is in terms of infrastructure, Facebook's efforts-the entire world with network connectivity, and provides developers with a mobile Internet servers and front-end tools, bottom.
Natural interaction style, and most need to solve is the noise. Now we are inundated with information, every day there are a large number of unfiltered information is passed to us. What should you do? Facebook also has made some progress in the area of artificial intelligence – picture machines are nothing more than a collection of pixels, but certain things, its combination of pixels is a regular. Facebook currently only pixel analysis of artificial intelligence, will be able to distinguish between more than 400 different types of movement, but also video.
But the real difficulty is the dialog background. For example, this problem: I'm at the Office, Bob on the Court playing basketball. I received a phone call, where I am?
For people, this question is simple, but the computer, it's almost double Dutch – to answer the above question, actually requires is to have a complete set of frameworks in the world, know the basic operation of the world.
While Facebook is using something called Memory Network way, simulate the human brain can instantly learn the current situation and answer the questions. Achieved end result, which is read and understand a reading comprehension about the ring, and in a similar way to answer related questions. It was just six months before Facebook breakthrough.
And when these things succeed, artificial intelligence is able to get picked for you the information you need – what you like, what you hate, and more in control. You will not be disturbed for the information you are interested in, your valuable time will be placed at your favorite or something.
In fact, the level of personal assistants, the big three have been published: Google Google Now, Siri Apple and Microsoft of Cortana. At this level is nakedly after high levels of artificial intelligence.
Next – is the key: virtual reality.
For the VR, questions and more: the concept of VR is good, but why now? After all, it was in the 80 's of the last century has been defined the concept.
Reason-a VR head in every part, and only today, after just to be able to integrate, are making virtual reality real sense – in the sense of a minimum threshold level.
>, For example, the screen only today can be put down in a 5-6 inch size 1920x1080 pixels above and level switching speeds up to 2ms.
>, For example, track only today, to be able to sufficiently low price guarantee of up to 0.25 ° angle error, error of 0.1 mm below the position level.
>, For example, was delayed until today to ensure within 20 milliseconds, complete next generation level screen rendering.
And the price of all these parts are produced, only today, in order to achieve the degree of consumer acceptance, and ensure that consumers can experience into another world – in the sense of feeling.
Every part, every technology must meet a minimum requirement, so we can group them together, the achievements of a virtual reality system.
This is virtual reality tank driving simulation game in 1980. Do you feel in the tank?
Following this, it is a virtual reality games will this year: EVE:Valkyrie actual video of the game: VR Box Virtual Reality headsets
Imagine the 1:1 sitting in a cockpit completely ... ... From then on, "our journey is the star of the sea" is no longer just a slogan.
After this video was at the scene, Mike asked: "can you feel the rush out of the tunnel: moment of force? You can feel in the VR. "
"You can ... ... (Pregnant pause for 3 seconds, keep running eyes, mouth tics) playing in the Oculus released a product to this...... " Introduced prototype of Crescent Bay and tell everyone this prototype was finally able to achieve people's unconscious mind think they entered another world when you see yourself in the VR while standing on the edge of the cliff, you have no way of moving your feet, even if your mind is clear and he is a safe room. "This year, we finally can be achieved by consumer-grade products in the minimum requirements. "
However, this and Facebook has anything to do with it? Mike asked you a question: "how many of you are going to the theatre on my own? "
"Why would you go with someone else in a closed space, there is no way to communicate with others, just to stare at a big screen? Why not go alone? "
"Because you are with others, sharing a space, creating a period of experience and memories. Both in the way of excitement and discussion on way back, to you and your family, friends, loved ones share some experiences, life. "
"This experience is the essence of communication between man and man, and is also the ultimate vision of Facebook and the ultimate task. "
Is to be with people who care, experience is meaningless. People who not arrived on the scene. Each one of those surprises. Ends of the Earth and remember.
"Four days ago, my four year old daughter riding on a smaller bike for the first time. At that moment, I wanted her grandparents, uncle and aunt all saw, I hope everyone can be transferred there to share my joy. "
Therefore, the people from the lowest level of the subconscious to be transported to another place in sense and the world's largest social networking platform integration at this moment.
This is Facebook goal for the next decade – really bring people together.
And you, the "true" the Word may be sniffed at – virtual reality, then what is false.
However, Anthony Jia Kui said: the reality is plastic, what do you want to bend, just what can turn (Gee)
Alfred said: the map is not the territory.
The Heart Sutra says: color does not vary empty, empty is the same color.
For science students, however, these are dishonest, we use the scientific method! To prove the world is fake, everything is wrong!
So, Michael Abrash and Mike Oculus chief scientist will be on stage at the various examples below tell you: "why, virtual reality will be very important to you, and sooner or later, you will be absorbed by the VR. "
The concept of virtual reality, have been buried in the last century. It is called impossible science fiction, science jokes and make people dizzy. But perhaps, this is known as early as well, and now, everyone began to refocus on VR. However, Abrash VR systematical thinking, or from the "avalanche" and "the players first," these two science fiction began. "Avalanche" Abrash to know the feasibility of virtual worlds, but "players first," let everybody see what VR can be like.
These science fiction to Abrash a thinking framework, but "the matrix" movies make him truly understand the virtual reality of meaning and significance.
The answer, as Morpheus in the world saying:
This sentence, will be able to let you know why VR is not only very interesting, but also changed the world – and sooner or later, you have to participate.
Next detail the meaning of this sentence:
Most people are concerned in the virtual reality of "virtual" on the word, it means people all sensory systems of the signal system of the building. But in fact, the real concern is the "real" Word. Morpheus saying little is the core purpose of virtual realistic.
Our consciousness, or "soul", and never truly realistic (if present) talked, actually, we have been in communication, but eye, ear, nose, tongue, body corresponds to a part of the brain.
We'll never know, the real world after what – prior to filter our sensory systems and sensory perception is just a very small part of the real world.
Take our most developed part of the visual perception system, for example, we can't see IR-UV-x line, we have only three primary sensory system, only 2 parts that are true high resolution viewing angle degrees about as big as a thumb nail size, each eye has a blind spot in addition to focus others are fuzzy ... ...
But even if we can provide very complete and accurate 360 ° angle of photons to record each to reach our eyes, we still have no way to establish a proper framework in the world.
For example some time ago the very famous blue black and white gold dress, images of the actual color and color of the environment suggests that there is a very large gap. Everyone has different perception of implied and actual. But that's not the most important, most important is that you can see in this sweeping through the world of the Internet controversy, everyone is convinced of his perceived correctness.
So, we can look at Morpheus that defines part of the sentence: real is simply the brain electrical signals to you.
How we perceive the world through such a limited information? Basically, we already have a static model of the world, and constantly update it according to the information. And it is this model is your world, and everything that you perceive.
We feel not the world, but the model of the world, we just get a feel for it.
The window illusion, for example, in this scenario, the window on some of the details suggests that your brain, leading to short circuit your brain resulting in a match the actual perception, your Visual system will think that turning a half turn of the window back. Because of this and contrary to reality, so you see a possible scenario.
Morpheus ask everyone a question, do you want the red pill or the blue pill?
But in reality, you put all the blocks, you will find both red and blue, are the same.
Rubik's cube on the left in the blue and yellow of the Rubik's cube on the right as well. This example tells us that reality is determined by what we perceive color for most of the time, fabricated out of the system, and its fabrication is far beyond your imagination.
There are more extreme examples, brain's fill color is completely true the other way around.
Perhaps you will say, these are color, color blindness in the world ... ... Then the shapes?
These are the normal horizontal even vertical shapes, right? But we simply add some ... ...
If you don't believe this figure and above the box is horizontal even vertical, you can take any straight stuff. Cause of this illusion is based on comparison to determine the direction of your brain, and these in the box on the corner of the point is to use this to make your brain produce illusion of direction deviation. This is an example of a two-dimensional shape, if in three dimensions and how?
Left clear the table looks elongated, short wide on the right. In practice, however, both exactly the same area of the table. In the three dimensional world, a two-dimensional size depends on various factors, your brain will adjust automatically. This adjustment is wrong here, but generally more conducive to our operations in the three dimensional world.
Shape up ... ... What is the movement? You might think that the observed motion must be based on real feedback.
Look left, and look to the right, note the direction of rotation. Now look to the right, light the left and note the direction of rotation. You try it again?
This principle is based on your perception of the eye – your peripheral vision with a low resolution, only notes that the high contrast, which is part black, and the black part is just blinking at a line with the counter-clockwise direction, so in your peripheral vision, would think that point in a counterclockwise direction.
Following is the summary of face recognition systems, automatic tracking of the observer's face ... ...
Even more outrageous was sound. Following the McGurk effect tells us, whose voice has been fixed in our brains. We hear will be influenced by what we see – meets for solid, ears are more likely is worthless.
Therefore, we believe that the reality, are simply hallucinations after millions of years of evolution – a exercise, people can easily survive and multiply in this dangerous world of delicate illusions. These examples tell us that once gave us the right kind of information, even though intellectually we know that true "reality" is like, we find it difficult to choose to feel everything.
In this way, let some extra highlight – the reality is that we can choose:
We can choose from diagonal above or from the diagonal below this box.
Interactive virtual labs founder Jeremy Bailenson of Stanford University said: "all reality is virtual. "
This brings us back to on the subject of virtual reality, as well as the technology why before and all the technologies are so different – VR is to allow you to experience a truly virtual worlds, and the example above tells us is that whether an experience is real, sensory system is entirely up to you to decide. Your senses are automatically done for you to judge, no matter how rational you feel more "clever".
In other words, when virtual reality well enough, is a reality.
These examples also tell us from another angle, we don't need perfect copies of real (not now), can make you feel really to go into another world.
For example, Crescent Bay picture 90 frames per second speed to your eyes, and pictures and of course in the real world is continuous. If the speed is reduced to 60, some people will feel blinks to 10, everyone knew it was fake. Crescent Bay show and real-world rendering varies greatly, but need only meet the input requirements of the brain, you can achieve the effect of sense of presence.
For input requirements, the most important thing is the feedback. For example, at Crescent Bay in one of the shows, when you stand at the edge of a skyscraper roof, and no one dares to step forward. And if you watch the videos on a big screen, no matter how high, no one needs to ask for a handrail.
Difference is that when you are in a prototype of Crescent Bay, turn their heads a little, you feel the movement of the vestibular apparatus, the corresponding Visual translation on Parallax, in full compliance with your cognitive models of the world. When delays of these correspondence is low enough (less than 20 milliseconds), your brain is messed up, these virtual artificial signal recognition as part of the real world. This is the biggest difference between virtual reality and all media.
VR is the key to Hack all of our perceptual system directly, make another reality takes over the so-called "reality" in our control.
This means that the real virtual reality, not only to create all possible experiences in the world today (such as hill climbing, swimming in the water), are able to create in the context of human perception ability going through experience (as in a fantasy world of flight). Real strip you fly.
Of course, there are many things to do today to ... ... Today's consumer grade technology even see their bodies in the virtual world has difficulties. But at the same time, it is also one of the most exciting – virtual reality there are too many people to design, where to optimize.
For example, force feedback. We hope to see his hand in the virtual world, prefer to interact with the virtual world, to touch the objects in the virtual world. And now the game controller, obviously there is no way to provide this experience. But in the virtual world and the gap between real-world use of the hands, and not so far away as most people think.
For example, the vision. Viewing angle, the pixel density, dynamic range, image quality, zoom has a great deal of space, and with these improvements, industrial design, and the volume will also be upgraded. What's the upside? Suppose we want to Crescent Bay quality under normal sight distance, and on your desk as a normal display, then unilateral resolution until at least 5kx5k of the Crescent Bay, Crescent Bay probably 20 times more pixels than the current times (small guess: 5000x5000/20=1,250,000; 1200x1080=1,296,000). Clam? You ask to retina@180 ° level? 16kx16k (200 times) ... ...
Sounds much better, doesn't require a lot of hardware updates, just need more iterative computation and algorithms.
Track will be an important element, especially tracking the human body, if your face needs to be mapped to characters in virtual reality, for others to see, then this means that the track had to capture the eye, mouth, and face muscles twitching. VR box 3D headset
Every part of these technologies, require people to correspond to each part of the human body have a deeper understanding of how to work, and now the level is far from enough.
Why, Abrash think this VR will recover?
First of all is about to release the consumer version, is attractive enough to bring any equipment are not experienced in the past. Every person who has no preset, take this device is mad with excitement.
Second is the advancement of the industry: Abrash have now publicly listed four: Oculus, Sony, Samsung, HTC, not counting the undercurrent of secret research and development company, just a few have been able to let everyone know how big is the thrust behind this trend.
Advancement of the 3rd is a long-term commitment, in Facebook's acquisition in the VR status can be assured, such large bets on the down, no one can recall.
Last but not least is the speed of evolution of technology. Abrash got his first computer (no floating point calculations), and nV has just released TitanX floating-point computing power compared to 33 raise about 1 billion times. This is in the context of competition and demand, the speed of technology evolution. This will also be the future of VR.
What is the next platform? For us, VR is not just the next platform, because it will create all of human experience, it may be the end of mankind. Of course, there is still a lot of debris on the flattened: nobody knows how to solve mobility problems in virtual reality, no one has perfect input scheme, not to mention the VR movies, social way in VR and people want to play the game. But, sooner or later, there is a solution to leave you are a variety of opportunities in the process. We all have the potential to become part of the tide in the VR – and each of us to think about is, when to join in on this wave of unforgettable? Maybe you want to be leaders, promoters; you may want to wait until after the maturity of the technology. But VR has the potential to change the world, and odd-very cool. Therefore, sooner or later you will come to our side. (Public welcome micro-letter number: vrerse)
