Chapter 278 How the Game Operates

Coming out of the brain-computer interface laboratory, Guo Yuan and the others went up to the negative floor.

Lin Yumo's AIDS research team is on this floor.

It was the first time Guo Yuan saw Lin Yumo at work.

At work, Lin Yumo was wearing a white coat, wearing glasses, her hair was combed into a ponytail, and she was staring at the microscope intently.

Guo Yuan didn't bother her, and went up with Su Yurou.

When they came to Su Yurou's office, Su Yurou asked the secretary to pour a glass of water for the two of them, and then asked Guo Yuan, "Guo Yuan, how do you plan to operate this game in the future?"

"How to operate? Free operation!"

"Free? Then how do you make money?"

"There are mainly two aspects. First, we need to spend money to buy our head-mounted brain-computer interface.

By now, Yurou, you should know the cost of the head-mounted brain-computer interface, right? "

Su Yurou nodded. According to the current experimental cost, the cost of the head-mounted brain-computer interface is between 400 and 500.

Implantable brain-computer interface is expensive because of the need for craniotomy to implant the corresponding equipment. Head-mounted brain-computer interface is completely unnecessary. According to this cost, it should be no problem to sell it for about 1000.

"According to my vision, as long as you buy a gaming helmet, you can log in to this virtual world and have your own adventures.

Not only that, but we have to impose layers of restrictions on the game, the most important being the play time.

I have already figured it out, when the game is released, I will limit the game time to a maximum of 3 hours a day.

And I don't plan to open the recharge channel, as long as you spend money to buy a helmet, you can play. "

Hearing this, Su Yurou already understood how Guo Yuan wanted to make money.

"Guo Yuan, are you planning to make money from the internal circular economy of the game?"

"Yes, at that time, players can earn in-game currency by fighting bosses and doing various life occupations. Currencies can be traded in the game, and can also be exchanged for Huaxia currency in proportion, but whether it is between players Whether it is trading or converting into Huaxia currency, we will take a commission.

Of course, we will also do some things that do not affect the game value, such as League of Legends skins and the like. "

"Then how do you limit the player's login time?" Su Yurou asked.

"It's very simple! The mobile phone and the helmet are bound. When the time comes, leave a QR code on the head-mounted brain-computer interface. Scan the QR code to connect the mobile phone and the head-mounted brain-computer interface. With the help of the mobile phone, you can complete the restriction. The operation of player login time."

"This is a good way." Su Yurou agreed.

"By the way, boss, do you want to buy a utility patent for the QR code of President Su?"

"No, the QR code was invented in 1994 by Mr. Masahiro Hara himself. Mr. Masahiro Hara voluntarily gave up applying for a patent on the invention of the QR code.

According to him, he did this for three reasons: the first patent is time-sensitive, and the protection period of the invention patent is only 20 years.It can be used for free after the expiration date, without authorization and payment. Mr. Yuan Changhong thinks this is very troublesome, and he doesn't want to keep staring at his patent all the time.

Second, Mr. Yuan Changhong has publicly said more than once on many occasions: I am an engineer, not a businessman.

Thirdly, the barcode appeared before the appearance of the QR code. Mr. Yuan Changhong felt that there was no charge for the barcode, so there was no need to charge for his QR code.

Therefore, in summary, Mr. Yuan Changhong did not apply for a patent on the QR code. "Su Yurou replied.

"So that's the case, then Mr. Su, what's the difference between a QR code and a bar code?" Cheng Shuqing continued to ask.

"I don't know about that. We don't use barcodes very much here. I don't know. Guo Yuan, haven't you ever stayed in an island country? Do you know?" Su Yurou asked.

"I really know this, in fact, in a sense, barcodes and QR codes are a pair of "brothers".

Barcodes were born in island countries after the 60s.

At that time, the island country entered a stage of rapid economic rise, and the sales of every supermarket in the island country were growing rapidly.

At that time, when cashiers were collecting money, they needed to manually input commodity prices for a long time, resulting in very slow efficiency, and under long hours of work, some cashiers' hands were prone to fatigue or even disease.

And so soon after, Norman Joseph Woodland, invented the bar code.

Later, barcodes have many disadvantages, such as relatively small data capacity, only letters and numbers, large size, and cannot be read after being damaged.

In order to solve these disadvantages, the QR code came into being in 1994.

The operating principle of the barcode is that the computer recognizes the black and white bars of uneven thickness in the horizontal direction, and can find out the product number information hidden in it.

The good brothers of barcode and QR code, to put it bluntly, are actually changing clothes for characters such as numbers, letters, symbols, etc., and dressing them up as black and white bars or blocks that can be recognized by mobile phone cameras.

Compared with the barcode that only carries information in one dimension, the two-dimensional code can carry information in both horizontal and vertical dimensions, and it is made into this square shape.

The QR code is to translate the information into small black and white squares, and then fill in the big squares, which is a bit similar to the answer sheets used in middle school exams.

To put it more simply, it is to turn the information into a pattern that can be scanned by the machine, and you can know the information contained in the QR code in an instant. "

"Then how did the information turn into this QR code pattern?" Cheng Shuqing asked.

"This brings us to the heart of programming: binary.

The numbers, letters, Chinese characters and other characters we usually use have completely different styles, but humans have invented a method so that they can be uniformly converted into a binary number sequence composed of 0 and 1. This conversion process is called coding.

After the characters become a sequence of numbers composed of only 0 and 1, a series of optimization algorithms are performed to obtain the final binary code.

In the last string of codes, a 0 corresponds to a small white square, and a 1 corresponds to a small black square. Fill these small squares into the large square in groups of 8, and this is a complete, The QR code pattern can be recognized by the mobile phone camera. "

"The two-dimensional code technology is actually quite mature now. Your company's technicians should be able to handle it, right?" Su Yurou asked.

"Well, our company recruited a group of technicians optimized by Ali some time ago. Ali is second to none in China in the use of QR codes. With their technicians, QR code technology is very easy for our company. can conquer."

"Then it seems that what is lacking in this game is our brain-computer interface, right?"

Guo Yuan nodded. From the current point of view, this is indeed the case, so Guo Yuan came to Longcheng Biology to check the progress of the brain-computer interface.
