Virtual reality (VR)When you see the image falling from any of the higher places, VR looks like reality so much that you scream involuntarily. In response to the question, “Why does VR look like reality?”, US news media Vox explains in a video.
How Virtual Reality Fools Your Brain-YouTube
At the beginning of the movie, a man wearing a VR headset and a controller is shown sighing while looking at his feet.
There is also a woman who shouts, “What should I do!”
They are playing “Richie’s board experience“A VR game. Richie” s Plank Experience “can enjoy the simulated experience of” walking across a single wooden board installed at the height of the 80th floor. “
Richie “s Plank Experience The graphics are getting better, but the light reflections still look unusual …
Many of the outer walls of the building are gentle …
The leaves of foliage plants are also squishy.
Looking at the details, the graphics roughness is noticeable, but Richie’s Plank Experience has succeeded in giving the player a “realistic experience” even with harsh graphics. For exampleSearch for “VR FAIL VIDEO” on YouTubeThen you can see the rest of the moss crazy about the VR game, dropping things, lowering others, and making the same mistakes.
Why does VR “look like reality when it doesn’t look like reality”?
“Seeing others experiencing VR” and “Actually experiencing VR” The most different point is “Oculus Quest 2With or without a VR headset like “.
Specializes in VR product testing, etc.Roomera“VR headsets are the biggest failure in VR marketing,” said Song Nguyen. According to CEO Nguyen, the fact that people who play VR and those who see it cannot get the same experience because of VR headsets is an obstacle to the spread of VR.
CEO Nguyen explains, “VR provides the brain with a completely different experience than watching video on TV.” When we watch TV, smartphones, etc., we recognize that the image on the screen is a “flat thing” like a photograph, and we do not want to avoid showing the image of the ball flying on the screen. However, if you do not show the image of the ball flying in VR, people will react to avoid it.
The cause of this reaction and the VR headset is that there are two screens in front of each eye. Not only are each screen placed near the two eyes, but each screen displays a slightly different image.
This mimics the mechanism by which a person “sees slightly different images in each eye” sees things.
The fact that the two eyes are looking at different images can be confirmed by the experiment “If you put one finger in front of your face and wrap it one by one”. When the left eye is closed, the finger position is slightly off when the right eye is closed.
Humans determine the depth by the difference in the visual information obtained by each eye. this is, “Stereoscopic (stereoscopic)“It is the true nature of what makes VR a three-dimensional image immediately due to the phenomenon. When the three-dimensional image moves up, down, left, and right according to the movement of one’s face, the human brain says,” Misunderstood as “real image”.
In addition, stereo is one of the elements that makes VR images look like reality. Richie “The sound of the wind that changes the viewing direction in s Plank Experience changes.
Frank Sternick of the University of Hamburg, who has been studying VR technology for nearly 20 years, said that the information obtained from VR images can not be clearly distinguished from the actual information, “I spent 15,000 years. Our brains did not have the problem of “separating CG images from actual images.” VR is a technology unfamiliar to humankind, but because it is a technology that replicates the innate visual field mechanism, the brain quickly adapts to the virtual environment.
According to Sternick, there are also research results in which humans obtain 80% of information visually, and the visual impact on the brain is enormous. In the experiment that “while walking straight in the VR image, it actually draws a circle with a radius of 20 meters”, the result was that both subjects did not know whether they were walking in a circle in the real world. The brain of a person who has gained it depends on vision.
The brain tends to look at information from the visual sense, even though there is a difference between information from the rest of the perspective that depends on visual information and information other than time. In the real world, even if the temperature is hot, the subject who showed the image of the snowy mountain in VR may feel cold. Using this phenomenon, experiments are being conducted to relieve pain by showing a VR image of a snowy mountain when a burned patient changes his bandage.
VR images in 2020 are still rough, but Style, Nick said, “CG will appear that is indistinguishable from reality for about 5 to 10 years. But that is the reality. In this case, it is an ethical issue. Will emerge. “
