MTL - Rebirth Starts at 7 Million-Chapter 235 virtual reality technology

Luo Fan knew who was lying here.

After he was with Li Jingyi in the previous life, Li Jingyi told him.

This girl named Li Jingyue is Li Jingyi's sister.

Li Jingyi's character has been relatively free since she was a child. When she was 8 years old, Li Jingyi went to play water with her friends. Li Jingyue was worried and she went with her.

But what everyone didn't expect was that one of Li Jingyi's friends encountered an undercurrent after entering the water and was about to drown. Li Jingyue went into the water and rescued the person, but she herself never came up again.

Originally, Li Jingyi didn't like drawing, and she didn't like any two dimensions.

Since she was a child, she liked the knights who flew over the eaves and the walls, and the majestic planes and tanks, but after Li Jingyue passed away, Li Jingyi began to learn to draw and watch anime. These are Li Jingyue's hobbies.

Li Jingyi's parents told her that she was not to blame for her sister's affairs. Li Jingyue volunteered to save people, and Li Jingyi didn't need to do things she didn't like to do.

And Li Jingyi said that she wanted to live with her sister's share.

Li Jingyi has changed since then, but it doesn't seem to have changed.

Her character is still hot and hot, and she doesn't look like a girl, but her behavior and way of doing things are becoming more and more like her sister.

"Sister, I have a boyfriend, come, let me introduce you, this guy is called Luo Fan, he is the boss of a big company, he started from scratch.

Yesterday I went to his house to meet his parents, and he should come to our house for the Chinese New Year this year.

I also have a job now, and I even bought a villa in Shanghai, I..."

Li Jingyi talked a lot, and Luo Fan was listening silently by the side.

Looking at Li Jingyi's appearance, Luo Fan felt very distressed. At the same time, he thought in his heart if there was a way for people to see their deceased relatives?

Suddenly, Luo Fan thought of a video he had seen in his previous life. A mother in Bangzi country lost her child. Later, when the VR technology matured, the mother wore VR glasses and saw herself again in the virtual world. children.

The so-called VR is the abbreviation of VirtualReality, which means virtual reality in Chinese. It is a computer simulation technology that can create and experience virtual worlds.

To put it bluntly, the core of VR technology is the virtual scene, the interaction between people and the virtual scene, and the interactive equipment. Through the interactive equipment with computer vision, touch, and hearing, people can feel immersed in the virtual scene, as if they are in the real environment.

VR technology actually appeared much earlier than most people think.

In 1838, the sun never set, a Sir Charles Wheatstone first proposed the concept of the stereoscopic mirror.

He believes that the brain will receive the reflected light sources of the same object from different points together, and it is the object that looks deep and immersive.

Combined with his conjecture, the earliest stereoscope appeared.

Around 1930, the science fiction novel "Pygmalion's Glasses" mentioned such a kind of virtual reality glasses.

When people wear it, they can see, hear, and smell what the characters feel in it, as if they were actually living in it. This is the first time in human history that the concept of virtual reality has been proposed.

In 1956, a cinematographer created the first VR gaming device through the novel and the concept of a stereoscope.

It's a huge machine that can hold up to 4 people at a time.

It also combines a variety of technologies to stimulate all human senses, including 3D video, audio, vibration, smell and atmospheric effects.

In 1968, the first VRHMD appeared.

This VR gaming device is connected directly to the computer, and although very primitive, already has a tracking system capable of tracking the human brain.

The first interactive VR platform was also exhibited at the Milwaukee Arts Center in 1975. It uses computer graphics, projectors and cameras, without the use of goggles or gloves, to make users feel an "immersive" experience through a dark room composed of its large screen.

By 1985, the first company to use VR gaming equipment to produce VR goggles and gloves was established.

The company, VPLResearch, has developed a range of VR devices.

In 1995, Nintendo introduced the VirtualBoy controller, the first portable console to display 3D graphics, but it was a commercial failure due to lack of color and software support.

The follow-up VR technology appeared more in various animation and game works, such as "The Matrix", the sixth theatrical version of "Detective Conan", "The Undead of Baker Street", and the popular "Sword Art Online" are all quoted. The concept of virtual reality.

It wasn't until 2010 that Google introduced a stereoscopic 3D mode for its Street View maps, with a 90-degree field of view never before possible, and relying on computer processing power to deliver the imagery.

This new development has stimulated and refreshed people's interest in VR.

In the same year, the concept of VR became popular in many countries in Europe and America.

In 2012, VR technology also began to appear in China, but the application is still very small.

In 2014, Facebook's company acquired OculusVR for $2 billion, and VR equipment has revolutionized since then, and VR equipment has grown rapidly since then.

That same year, Sony announced that it was developing Project Morpheus, a VR gaming device for the PS4.

Google launched Cardoard, Samsung launched Gear. More and more companies are exploring the possibilities of VR gaming devices, including adding innovative accessories.

By 2016, the concept of VR has become quite popular in China, and many domestic companies have begun to join the ranks of VR.

Luo Fan just thought of letting the living see their deceased relatives, which was realized at this time.

This should be regarded as a type of psychotherapy. Many people who have lost their loved ones cannot get out of their grief for a while. Some psychotherapy institutions use the function of VR immersive experience to help patients with psychotherapy.

Virtual reality technology has infinite possibilities in a sense!

But unfortunately, VR technology has fallen into a bottleneck after it ushered in vigorous development in 2012 to 2016.

It boils down to two reasons:

The first user experience is too bad. As far as the current VR experience is concerned, many users will experience physical discomfort such as dizziness when using it.

There are many reasons for physical discomfort, such as resolution, image ghosting, image delay, discontinuous depth perception, and so on.

In the final analysis, there are too many sensory organs in the human body, constantly perceiving surrounding information and transmitting it to the brain at all times, and the brain constantly processes this information to determine whether it is normal and "reasonable".

So, if there is conflicting information that the brain doesn't recognize, the brain gets "troubled," which in turn creates discomfort.

The use of VR will greatly accelerate the fatigue of people's brains, and even cause dizziness and nausea, which will greatly shorten the VR experience time and affect the user experience.

The second is because of the price: VR products from big brands are very expensive, and the expensive ones are even more outrageous.

Take the average mobile phone for comparison, 3,000 yuan can already buy a mobile phone with high performance.

And 3,000 yuan to buy high-end VR equipment is not enough, and it is far worse.

Of course, there are actually many fake products on the market. This kind of VR equipment is very cheap, and you can buy one for dozens or hundreds of dollars.

But this kind of equipment is too limited, and the experience is very bad, it is easy to get dizzy, and cause various adverse reactions.

Thinking of this, Luo Fan sighed, VR technology will have such huge limitations in 2022, let alone now.

However, Luo Fan had already made a decision at this time. When he went back, he would allocate funds to start entering the VR field. This project did not want to make money. It would be a success if Li Jingyi could see her sister.

"Boom~"

There was a muffled thunder not far from the cemetery, Luo Fan and Li Jingyi looked up at the same time, and found that the sky had fallen for some unknown time.

The black clouds above the head have gathered, gloomy, and the wind is whistling in the sky and the earth, blowing the grass and the leaves.

"Looks like it's time to go!" Li Jingyi muttered to herself.

"Your sister doesn't want you to get caught in the rain either."

"I know, sister, we'll see you next time when we leave." After that, Li Jingyi and Luo Fan turned and left the cemetery together.

Coming out of the cemetery, the wind was stronger, and the direction of the wind was exactly the direction that Luo Fan and Li Jingyi went down the mountain.

When Luo Fan was a child, he liked to run wildly when the wind was down, which made him feel like the wind was running faster than the wind.

In junior high school, Luo Fan gradually felt that this kind of behavior was stupid and naive.

This may be the reason that people on the Internet will lose their innocence once they grow up.

"pat~"

A drop of rain fell from the sky and hit Li Jingyi's eyebrows.

"It's raining!"

"We are quite far from the parking lot below." Luo Fan said helplessly.

"A few steps ahead there is a pavilion where we can take shelter."

"Looking at the weather, it might rain heavily. If you stay in the pavilion, you may be trapped." Luo Fan said.

"Then run?" Li Jingyi asked.

"I can do it, see you."

"I don't care anymore, it's okay to get caught in the rain." Li Jingyi is not afraid of the rain at all. Her favorite thing is the rain. When she was a child, she often put away her umbrella and walked in the rain on purpose.

"Let's go now before it rains heavily!"

"Well! Then hurry up!" Li Jingyi's expression became serious again, "No! Run!"

After speaking, Li Jingyi took a step forward and rushed down the mountain. In the blink of an eye, Li Jingyi had already passed a small bend, and she could not be seen in front of her, so Luo Fan quickly trotted to catch up.

After running, Luo Fan felt that the air was cool and the wind was very comfortable.

After Luo Fan turned the corner, he found that Li Jingyi was waiting for him at the corner.

He jumped out childishly and wanted to scare Luo Fan.

Luo Fan naturally wouldn't be frightened by her little tricks, but Li Jingyi was in a bad mood today, so Luo Fan simply obeyed her and pretended to be taken aback.

"Your acting is too exaggerated, at least it's natural!" Li Jingyi complained.

"I'm not an actor, so don't ask too much!"

"Cut! It's not sincere to coax others, he's really a scumbag." After speaking, Li Jingyi started to run again, followed by Luo Fan.

When the two ran down the mountain, it was raining heavily.

Originally Luo Fan wanted to hurry to the car, but Li Jingyi stopped in front of a tin room.

On the small bench in the room sat an old man in security clothes.

"Master, you are alone today!" Li Jingyi said as she walked into the tin room.

Hearing this, the old man raised his head and glanced at Li Jingyi with a smile: "Li girl is you! Come to see your sister again?"

"Well, we just came down, sir, this is my boyfriend Luo Fan."

"Hey young! Girl Li has a boyfriend, don't forget to tell the uncle when you get married, I will definitely be there."

"Okay!" Li Jingyi agreed decisively.

This uncle's surname is Zhou. He is 81 this year. He has been guarding the gate here since Li Jingyi first came to this cemetery.

As Li Jingyi came more frequently, the two gradually became familiar with each other. Only then did Li Jingyi know that Uncle Zhou came here as a security guard to guard the entrance of the cemetery because her wife was inside.

Uncle Zhou's sons and daughters are all capable. They have persuaded Uncle Zhou not to guard the gate here more than once, and they will give him old age and death.

But Uncle Zhou refused. For many years, Uncle Zhou has been guarding the cemetery. He said that he did not want his wife to feel lonely.

When Li Jingyi asked Uncle Zhou whether he felt lonely when no one was there, Uncle Zhou said he was used to it.

After chatting a few more words with Uncle Zhou, Li Jingyi said goodbye to him and left.

Li Jingyi walked slowly behind Luo Fan, and after a while, Li Jingyi said, "Uncle Zhou is very old, and now he is much more haggard than when I saw him last summer vacation."

"In fact, there is nothing to be sad about. This is Uncle Zhou's own choice. He is not afraid of natural death, but is looking forward to death." Luo Fan said.

"I know, Uncle Zhou should miss his boss very much!" Li Jingyi sighed.

"Yeah! In a sense, when his boss passed away, Uncle Zhou had already finished his life, and he may have been prepared long ago. For him, this is not something to be feared and saddened by. thing.

If Uncle Zhou wanted to, there should be more people with him when he left, instead of walking quietly like this.

But no matter what, this is his own choice, he must have thought of different ways to leave, but in the end he chose this one. "

"Luo Fan, what do you think happens when someone dies?" Li Jingyi asked after a moment of silence.

"Dust to dust, dust to dust."

"What an unromantic answer."

"Then what answer do you want to hear?" Luo Fan asked back.

Li Jingyi didn't speak, and a picture emerged in her mind involuntarily:

It might have been a rainy day like today, because it was raining when Uncle Zhou's wife died.

Uncle Zhou may die listening to the sound of raindrops falling like today.

Maybe at the last moment of his life, Uncle Zhou could "see" his wife who had been with him for many years, walk out of the rain with an umbrella, and pick him up to go to another world!

"Boom."

The sound of thunder interrupted Li Jingyi's thoughts, and the rain became heavier. Luo Fan and Li Jingyi hurriedly got into the car and drove away from the quietest place in the city in the misty rain.
