Is virtual or real it is really important for VR

"Editor's note" author of the Tiber, VR senior industry practitioners.

As a virtual reality industry, of course I have many opportunities to experience virtual reality. Wearing VR, I entered another world: there is a desk in front of me, scattered laid some stationery in front is not too far from a display, showing some pictures. I can turn to see what's behind me, you can also close to observe the details of the stationery on the tables. The world looks so realistic, I can't help but think that this is true. Perhaps this is "virtual reality" (Virtual Reality) the source of the name. Here, we may have to ask the question: If one day the development of virtual reality to the matrix phase, how are we to distinguish between real and unreal?

This is a matter of metaphysical philosophy. Here we might as well talk about a real problem: how to tell if a photograph is PS?

PS,Photoshop for short. We see those magazine beautiful landscapes and figures, according to the times, we will say that this picture is PS; and a circle of friends who every day take pictures, we know is PS. It can adjust exposure, brightness, white balance, saturation, color curve, and spots on the face can also be removed, or the leg lines become thinner. In short, use software, neither Photoshop nor the Mito is Instagram or VSCOcam, we became more beautiful pictures, but even less real.

Then, in front of the PS picture real?

If the human eye can see pictures of long exposure?

Consider the perspective of digital cameras. Mechanics of the camera eye is actually the same: Photon passing through the lens, falling on the sensor into corresponding signals; the camera's electronic system to collect electric signals, processed by the algorithm, and restore the color and brightness, and form we see here. In this one, algorithms to explain which parts of the signal is red, what aspect of how bright, adjust the options ranging from color to white balance; software processing, and processing within the camera, logically, what is the difference?

More metaphysical question is, from the signal back into an image, a series of processing steps, what we might call "real"? After that step, then let it be true?

In this sense, becomes a relative term: our cognition of what is true, is certainly coming from our own world view. We can't help but picture compared with the scenes we see through the eyes of, if the photos in the blue like the blue color of the sky and we see, we feel that this photograph was taken of PS. But the question here is, the camera sees the world, is by Senor electronic systems and software algorithms that describe the world and we see the world is composed of retinal optic nerve system and brain's portrayal of the world, form the basis of the world will be different, how can we believe that the camera should see and we see the world?

Extended to more areas of science, a fraction of the visible wavelength spectrum, we cannot see infrared and ultraviolet light, not to mention long or hard-x-ray. IR UV Longwave and there is no x-ray? Can see wavelengths of biological or electronic system is more real than we see in the world?

So here we can make appropriate conclusions: the photo itself is not real or not, any photos would be a view of the building. Then we can use virtual reality as a reverse process of photography: photography is collecting photons and convert electrical signals, while virtual reality is converting the signal photons, eventually back into electrical signals in the brain.

Oculus Michael Abrash, Chief Scientist at OculusConnect 2 and F8 's keynote speech was made by the General Assembly on this topic--virtual and real where is the limit? He used a series of evidence showing a little-we are "what's real" itself is a construct, let tens of millions of years of evolution to the world itself-we have already established model to observe the world through this model. Abrash lift has several example: say perspective completely errors of Windows, because we of Visual system has a perspective relationship should is how of basic assumed; say to within concave of dinosaur head model, because human see face on will think face is to outside raised of; also say, in also of pronunciation Xia, mouth type of different on will caused we of for pronunciation of cognitive differences. cover Kenzo iPhone 6

Abrash lecture wants to say is two things:

First, we do not have a thorough understanding of how the human visual system works;

Second, virtual reality and real, and there is no philosophical difference.

Therefore, Morpheus (Morpheus, think about why Sony VR project named Project Morpheus) asks what is real when he asked one question.

Virtual reality: is it real? It wasn't. And true in itself: is it real?
