A hint of curiosity suddenly appeared in Wang Tong's eyes.
I saw him looking at the helmet up and down, and asked Xu Yun with some doubts:
"Dr. Xu, if I remember correctly...the past designs of MR and VR equipment seem to have an appearance similar to glasses, right?"
After saying that, Wang Tong made a square gesture around his eyes.
Hearing this, Xu Yun looked at Lu Xiao who was standing beside him, and the corners of their mouths raised a slight arc at the same time.
The two technologies of MR and VR are easily confused conceptually. Therefore, when mentioning MR, most people will think of an appearance that is similar to traditional VR and looks a bit like an eye mask.
In fact, most MR equipment does adopt a similar design.
For example, the VisionPro device released by Apple last year used MR technology, but because it was extremely close to the appearance of VR glasses, many people thought it was a VR product. In order to increase search volume on the e-commerce platform, Apple even added
Words like VR are also added here.
Therefore, in Wang Tong's subconscious mind, the MR equipment should be similar in appearance.
"..."
Looking at Wang Tong who was a little confused, Xu Yun smiled softly and explained:
"Brother Wang, in fact, at the beginning, we did adopt the design method of VR glasses."
"After all, glasses are more convenient than helmets."
"But later during offline experiments, we found that if they were wearing a device similar to an eye mask, tourists would easily bump into each other while viewing the exhibition."
"So after discussion, we designed this device that is similar to a racing driver's full-face helmet - compared to VR glasses, everyone has worn a helmet to some extent."
As Xu Yun said.
At the beginning of the project, Lu Xiao and the others also designed according to the appearance of traditional eye masks.
However, during the actual experience, Xu Yun and others quickly discovered a problem:
Since most people have never used VR equipment before, they showed obvious discomfort when wearing VR glasses to visit the exhibits.
After all, VR glasses are said to be glasses, but in fact they are quite heavy when worn on the head. They are fine in small scenes such as the bedroom, but it is a bit difficult when large-scale movements occur.
At the same time, although the aisles in the National Expo exhibition hall are not narrow, they are certainly incomparable to open-air venues. Wearing glasses can easily cause collisions. Even Lu Xiao herself bumped into the glass cabinet of the booth once during the experience.
So after repeated discussions, Lu Xiao and others finally came up with the design of this full-face helmet.
Although the full-face helmet weighs more than traditional goggles, its center of gravity is dispersed to 360 degrees. The thick sponge-like cushioning structure at the bottom of the full-face helmet can also greatly relieve the pressure on the cervical spine in terms of ergonomics.
In addition, Xu Yun also asked the Academy of Sciences to optimize an air inlet and outlet structure for breathing. When using it, there is no need to worry that the closed helmet will affect human breathing - in fact, there is a heart rate system inside this thing. Once the heart rate
If a problem occurs, the logistics staff can immediately find the corresponding tourist to handle it.
more importantly.
Whether traveling or fishing these days, who the hell hasn’t worn a helmet...
........
Xu Yun then handed the MR headset to Wang Tong and introduced him to the use of the device:
"Brother Wang, the button on the left is the equipment switch. Just press it after you enter the hall."
"At that time, the helmet will temporarily remove a baffle to block your line of sight, and it will automatically turn on in about ten seconds. There will be a prompt sound before turning on. We have also adjusted the indoor light so that there will be no sudden highlights.
The scene affects tourists’ vision..."
"The button on the right is the emergency call button. If you feel any discomfort, you can press it to call the duty personnel..."
"As for the shell of the headset, it is made of high-strength carbon fiber reinforced composite material, which is light and strong. In theory, there will be no problem if you hit the ground with your head - of course, we do not recommend such an attempt...
..”
"In addition, we are also equipped with drinking water with a straw. The straw can be inserted into the mouth through a hole..."
"If you want to communicate with Sister Zhang, you can press the button below. Our equipment supports up to six people on the same channel..."
"As for the viewing time of each hall, which is half an hour, we have arranged a total of three exhibition halls this time. The longest total viewing time is 90 minutes. There are snacks such as buns at the exit...
..."
Xu Yun gave a very detailed introduction. Huadun Biotech and China National Expo have already developed very complete services for today's exhibition...or a supporting response system.
Even considering that some Internet celebrities these days may even do extreme things in order to become famous, the glass in the exhibition hall is made of specially made high-strength materials. Even if someone goes crazy and hits the display cabinet, it will not cause any harm to the exhibits.
Wait for Xu Yun to finish his introduction.
Wang Tong and Zhang Ying each took the helmets and put them on their heads at the entrance.
As Xu Yun introduced.
This full-face helmet is designed very delicately. Except for a slight feeling of stuffiness when worn on the head, there is no obvious feeling of heaviness. Instead, the whole thing looks very light.
Then Wang Tong took a few breaths and found that its ventilation effect was indeed excellent.
To know.
Generally speaking, whether it is a full-face helmet or a flip-up helmet, due to structural problems, the air blown out when you exhale forcefully will usually hit the mask and bounce back to the face, giving people a very stuffy and strange feeling.
If you are myopic and wear glasses, your vision will often be affected by fog.
However, Wang Tong did not feel the rebound of gas in the headset, which meant that the air he exhaled was sent to the outside along the exhaust port.
Upon seeing this, Wang Tong gave Xu Yun a thumbs up and waited aside for half a minute. Zhang Ying has more than 700 degrees of myopia, so the staff adjusted the matching degree for her headset.
This chapter is not over yet, please click on the next page to continue reading the exciting content! The headset designed by Lu Xiao comes with a diopter adjustment, and it is 200 degrees higher than the 700-degree self-adjustment limit of Huawei's VR GLASS.
What makes Xu Yun feel crazy is that Lu Xiao actually considered the impact of astigmatism. He is worthy of being a Virgo player...
A full two minutes passed.
Wang Tong and Zhang Ying have just finished debugging.
Then the young couple connected to a private voice channel with just the two of them through the Bluetooth of the headset, and walked into the North 12th Hall hand in hand.
The entrance to North Hall 12 uses a closed double-layered dark glass door, so the inside cannot be seen clearly from the outside. When the young couple pushed the door open and walked into the exhibition hall, Zhang Ying's soft voice sounded next to Wang Tong:
"Wow, what a big exhibition hall..."
Wang Tong also nodded.
The exhibition hall that appeared in front of them at this time was about several thousand square meters. As soon as they entered the exhibition hall, they were greeted by rows of neat and impressive glass display cabinets:
Above the display cabinet are pieces of transparent tempered glass. These glasses are clear and translucent, like small windows. Their edges are obviously finely polished, smooth but not sharp, which not only ensures the safety of the audience, but also adds to the overall beauty.
sex.
Underneath the display cabinet is a carefully carved wooden base. As a science student, Wang Tong couldn't tell the specific material, but even a layman like him could tell that the wood was warm, delicate and elegant, and definitely not ordinary wood.
The layout of these display cabinets shows an obvious [plate] shape, which maximizes the use of the exhibition hall space. The width of the aisle is about two meters, which can accommodate two ordinary people without hearing loss.
As for the inside of the showcase...
I saw light yellow ancient books neatly arranged among them, which were obviously the legendary... "Yongle Dadian"!
"Hey, that's so strange."
Just when Wang Tong was feeling a little excited, Zhang Ying's voice came from his earphones again:
"Wang Tong, why is there no tour guide in the exhibition hall?"
Wang Tong was stunned when he heard this, and then subconsciously looked around the scene, with a trace of astonishment clearly appearing in his eyes.
As Zhang Ying said, except for those tourists who entered earlier than Wang Tong and Zhang Ying, there was no staff in the huge exhibition hall!
This is very strange...
be honest.
In this kind of exhibition, security personnel are arranged in a dark place. Wang Tong can understand and even support it. After all, for tourists, patrol work will affect the exhibition experience to some extent. The entrance security check and the special glass material do not require security personnel.
Always keep an eye out for anyone causing trouble in the open.
but.....
For such a big exhibition, you have to have a tour guide, right?
Not to mention that each person is assigned such a high standard, but there are ten or twelve people in the head office, right?
This is a very reasonable request, and it is not difficult for the National Museum to achieve.
But now in this exhibition hall, Wang Tong did not see any tour guide.
Then Wang Tong touched his chin and guessed:
"Is it because there are words on the exhibition hall, and the National Museum of China is going to let us read the words for a tour? Or is there something wrong with this helmet?"
Say it.
Wang Tong also knocked on the shell of the headset. With such a big thing covering his head, Wang Tong couldn't ignore it.
But before Zhang Ying had time to speak, a mechanical prompt sounded in Wang Tong's earphones:
"Dear visitors, you have entered the North 12th Exhibition Hall of the National Museum. Please follow the instructions before entering to activate the head-mounted display device to complete the model activation."
"If you do not perform any operation within ten seconds, the headset will automatically activate the relevant program..."
Wang Tong was stunned when he saw this. After he came to his senses, he quickly fumbled around on the left side of the headset for a few times. He found a button and pressed it immediately.
I almost forgot about the real thing...
Zhang Ying on the other side also pressed the button, and then a baffle appeared in front of the two of them, blocking their sight.
at the same time.
Inside the headset, a preset program begins to activate.
Among them, the most important model of the exhibition hall was transmitted and received from the cloud in an instant, and the details were accurate to every fine line carved on the lower half of the booth. This was a sample of the model completed in advance by Lu Xiao and others.
Immediately afterwards.
The headset begins to verify the light data.
Lu Xiao and others had made an extremely fine division of the exhibition hall in advance. In layman's terms, they had established a three-dimensional coordinate system. After the headset was activated, it first determined the specific position based on the sensing equipment. In theory, each position had an impact on the center of the ceiling.
Lighting equipment has different light reception rates. As long as the verified data and the preset are correct, the level will be passed.
Another second passed.
The headset has entered the most important link - floating point sample adoption.
Floating point samples may sound complicated, but in this case they are... visitors.
That's right, tourists.
Lu Xiao and others can build a model of the exhibition hall many days before the exhibition, but they cannot model it in advance for visitors to the exhibition - it is impossible to let the visitors cooperate with you to practice it first.
It is even more impossible for Xu Yun and the others to directly cancel the information scanning of tourists, otherwise after the MR headset is activated, Wang Tong... In other words, each tourist can only see the booth and not other people visiting the exhibition.
There may be couples holding hands but unable to see each other in the headset. It may also happen that there seems to be a ball of air in front of you, but you bump into one or even several people while walking... This picture is also
Taite Meow is so supernatural.
Therefore, the only way is to use the device activation as an excuse to conduct temporary modeling after visitors enter.
At the same time, this kind of modeling is not a one-time operation, but is recorded and simulated every moment. This process requires a huge amount of computing power.
Fortunately...Xu Yun and the others have Tianhe-3 to use this time.
In just 0.53 seconds.
More than 7 billion bytes were transmitted to the cloud. Four of the six cabinets of Tianhe-3 entered the running state, and the calculation was completed in 0.86 seconds.
at the same time.
Wang Tong suddenly felt a little itchy on the wing of his nose. He stretched out his hand and scratched his nose. A new set of data was born from the subtle movements.
This time, the headset recorded a middle-aged woman about ten meters in front of Wang Tong. In just 0.00003 seconds, the woman's earrings were analyzed into pixels, uploaded and the model was completed.
The third second...
The fifth second...
that's all.
When the time came to the fourteenth second, the prompt sounded in Wang Tong's ears again:
"Dear visitors, your head-mounted display device has been activated and the bezel will open within five seconds."
"five four three two one......"
After a five second countdown.
Suddenly, Wang Tong's eyes lit up slightly, and his vision returned to normal.
As Xu Yun said, the angle of incident light went through rigorous simulation calculations by Lu Xiao and others. The light will be completely filled within three seconds after the baffle is opened, so Wang Tong did not feel any discomfort during the whole process.
After regaining his vision, Wang Tong subconsciously looked forward.
As soon as he raised his head, his whole body trembled violently:
"Damn it, what the hell is this?!"
...

Higgs passed away, and there is one less person among the living physicists. A long sigh
