Luo Fan knew who was lying here.

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

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

Li Jingyi's character has been relatively out-of-the-box since she was a child. When she was 8 years old, Li Jingyi went to play in the water with her friends. Li Jingyue was worried and she went along with her.

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

Originally, Li Jingyi didn't like painting, nor did she like two-dimensional things.

What she liked since childhood were knights flying over walls and flying over walls, and majestic airplanes and tanks. But after Li Jingyue's death, Li Jingyi began to learn painting and watch anime. These were Li Jingyue's hobbies.

Li Jingyi's parents told her that she was not to blame for what happened to her sister. Li Jingyue volunteered to save people, and there was no need for Li Jingyi to do things she didn't like to do.

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

Li Jingyi has changed since then, but she seems to have stayed the same.

Her character is still fiery and not girlish, but her behavior and the way she handles things are becoming more and more like her sister.

"Sister, I have a boyfriend. Come on, let me introduce you. This guy's name is Luo Fan. He is the boss of a big company and he is a self-made man.

Yesterday I went to his house to meet his parents. He should come to our house during the Chinese New Year this year.

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

Li Jingyi talked a lot, and Luo Fan kept listening silently.

Looking at Li Jingyi's appearance, Luo Fan felt very distressed. At the same time, he thought in his heart, is there 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 from Bangzi Country lost her child. Later, when VR technology matured, the mother wore VR glasses and saw herself again in the virtual world.

's children.

The abbreviation of ity, which means virtual reality in Chinese, is a computer simulation technology that can create and experience a virtual world.

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

VR technology actually appeared much earlier than most people think.

In 1838, Sir Charles Wheatstone first proposed the concept of a stereoscope.

He believes that the brain will receive reflected light sources from the same object from different points and combine them together to make the object appear to have depth and immersion.

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 the things the characters inside feel, just like they are living in it. This is the first time in human history that the concept of virtual reality has been proposed.

In 1956, a cinematographer used this novel and the concept of a stereoscope to create the first VR gaming device.

This is a huge machine that can accommodate up to 4 people at a time.

At the same time, it combines a variety of technologies to stimulate all the senses of the human body, including 3D video, audio, vibration, smell and atmospheric effects.

And in 1968, the first one appeared.

This VR game device is directly connected to the computer. Although it is very primitive, it already has a tracking system that can track the human brain.

The first interactive VR platform was also exhibited at the Milwaukee Art Center in 1975. It used computer graphics, projectors and cameras, without the use of goggles or gloves, to allow users to experience the experience through a dark room composed of its large screen

to an "immersive" experience.

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

The company called Arch develops a series of VR devices.

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

Subsequent VR technology has appeared in various animation and game works, such as "The Matrix", the sixth theatrical version of "Detective Conan", "Dead Man on Baker Street", and the popular "Sword Art Online".

The concept of virtual reality.

It was not until 2010 that Google introduced a stereoscopic 3D mode for its Street View map, which had an unprecedented 90-degree field of view and relied on computer processing power to transmit images.

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

In the same year, the concept of VR began to become popular in many European and American countries.

In 2012, VR technology also began to appear in China, but its application was still very niche.

In 2014, Facebook acquired the company for US$2 billion. Since then, VR equipment has undergone revolutionary changes, and VR equipment has developed rapidly since then.

In the same year, Sony announced that it was developing Heus, a gaming device.

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

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

Luo Fan's idea of ​​letting living people see their deceased relatives was realized at this time.

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

But unfortunately, after booming in 2016, it fell into a bottleneck.

Ultimately there are two reasons:

First, the user experience is too poor. As far as the current VR experience is concerned, many users will experience dizziness and other physical discomforts when using it.

There are many reasons for physical discomfort, such as resolution, picture ghosting, picture delay, discontinuous depth perception, etc.

The final analysis is that there are too many sensory organs throughout the human body, which are constantly sensing surrounding information and transmitting it to the brain. The brain is constantly processing this information to determine whether it is normal and "reasonable".

Therefore, if there is conflicting information that the brain cannot recognize, the brain will feel "disturbed" and feel uncomfortable.

Using VR will greatly accelerate people's brain fatigue, and even cause dizziness and nausea, which will greatly shorten the VR experience time and affect the user experience.

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

Just compare with ordinary mobile phones. You can buy a mobile phone with average performance for 3,000 yuan.

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

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

However, this kind of equipment has too many limitations, and the experience is very bad. It can easily make you 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 up his mind at this time. He would allocate funds to enter the field of VR when he returned. This project was not about making money, but it would be considered a success if it allowed Li Jingyi to meet 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 turned cloudy at some point.

The black clouds above our heads have gathered and become gloomy. The wind howls between the sky and the earth, causing the grass to sway and the leaves to wash.

"It seems it's time to go!" Li Jingyi murmured to herself.

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

"I know, sister, let's go and see you next time." After saying that, Li Jingyi and Luo Fan turned around and left the cemetery.

After coming out of the cemetery, the wind became stronger, and the direction of the wind was exactly the direction Luo Fan and Li Jingyi went down the mountain.

When Luo Fan was a kid, he loved running when there was a tailwind. This would make him feel like the wind was running faster than the wind itself.

When he was in junior high school, Luo Fan gradually felt that this kind of behavior was silly and naive.

This may be why people say on the Internet that once they grow up, they lose their innocence.

"Pap~"

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

"It's raining!"

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

"There is a pavilion a few steps further. We can take shelter in the pavilion."

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

"Then run down?" Li Jingyi asked.

"I can do it, it's up to you."

"I don't care anymore, it's okay to get caught in the rain." Li Jingyi is not afraid of getting caught in the rain at all. What she likes most is raining. When she was a child, she often deliberately put away her umbrella and walked in the rain.

"Let's leave quickly before it rains heavily!"

"Well! Then walk faster!" Li Jingyi's expression suddenly became serious again, "No! Run!"

After saying that, 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 could no longer see her figure in front of her. Luo Fan quickly ran after her.

After starting to run, Luo Fan felt that the air was cool and the wind was very comfortable.

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

He jumped out very childishly and wanted to scare Luo Fan.
