After the key breakthrough of the thinking sensing technology, it is equivalent to opening up a broad development space, and the core of the thinking technology is going in two directions, one is a more sensitive and miniaturized thinking sensing transmitter, and the other is a feedback device.

Compared with the latter, although the road to miniaturization of the sensing device is difficult, it has seen the direction from afar, so the rest is to move towards the goal step by step, which is not difficult at the theoretical level, but difficult at the realization level.

Su Weimin has never been interested in this kind of research project that lacks challenges, so when he saw this fact clearly, he immediately turned to another direction.

Xing Yutong tried to study the software at the beginning, but soon Xing Yutong found that the essence of the algorithms and new network transmission protocols involved in the software is actually the positioning problem of virtual reality technology, that is, the height problem.

To put it simply, if you use a headset and then use pure vision and sound to perform virtual reality operations, it is a fairly simple thing, just like remote control model aircraft in reality, there is no difficulty, and even easier, because you can set more action packages in the program, simplify the operation, and even automatically limit unreasonable operations.

There are many people who can't control remote-controlled planes in reality, but there are no people who can't control remote-controlled planes in the virtual world, so Xing Yutong's research goal is not this at all, but the reverse feedback of the program.

If virtual reality is simply realized in the form of mental manipulation, then this virtual reality is too rudimentary, compared to the real reality. It's not just about the lack of smell, taste, and touch. Even if only one is missing. Virtual reality is always virtual and completely unrealistic.

Xing Yutong found that in order to achieve the highest possible realism, it is necessary to accurately convey the feedback of the virtual world to the user, which is not something that can be achieved by the shaking seats, electric pumps that can spray water, and blowers that can emit fragrance in 3D theaters, let alone the blowers. In order to do this, the user who uses virtual reality must use a huge device.

If it is only to use this workaround to create a virtual world, Xing Yutong needs to design algorithms and digital models that convey these feelings and interactions, which is not very difficult. However, Xing Yutong is obviously unwilling to accept this compromise approach, she is a perfectionist, she is also a warlock, she stands at a very high height, she thinks that since the thinking device can transmit people's thoughts, then it should also be able to transmit feedback. It's like the Ruyi Illusion God Array.

So from the very beginning, Xing Yutong's goal was to combine the Ruyi Illusion Divine Array with the Thinking Sense Technique. Therefore, the virtual reality system and network she wants to design are completely different from the existing network technology, not to mention the core technology real-world transmission and transformation, the network exchange itself needs to transmit an amazingly large number of jù, and the requirements for the speed are also amazing, and the transmission process is also required to be equal, this kind of number jù transmission, at least the current technology and standards are not possible.

Despite the difficulties, Xing Yutong is still very persistent in designing the virtual reality network in his mind, which involves a lot of things, including new algorithms and standards, including reverse thinking equipment, high-speed transmission system, and the transmission system involves hardware equipment such as digital processing, transmission, etc., this idea is definitely a huge project, and the difficulty coefficient is as high as 9, and it is precisely because of the high difficulty that Su Weimin rushed in like a moth to a fire, and the two of them were immersed in it day and night. The painstaking research process began.

The first direction chosen by Su Weimin and Xing Yutong is the reverse feedback device of the thinking sensor.

The difficulty of manufacturing reverse feedback equipment is very high, and this difficulty does not lie in the hardware, however, they have a very good beginning and model in their hands, which is the Ruyi Phantom God Array, although they do not fully understand the detailed principle of the Ruyi Phantom God Array, and they cannot make the Ruyi Phantom God Array, but they have the framework principle of the Ruyi Phantom God Array provided by Fangshi in their hands, which is enough.

In fact, Su Weimin didn't think he needed to build a magical device that could instill sight, hearing, taste, smell, and touch into people's brains according to network numbers, which was too difficult, and even more unrealistic than realizing Xing Yutong's high-speed and large-bandwidth transmission network.

If you want to achieve panoramic feedback of virtual reality, the user's own imagination is the key, just like the illusion cast by the warlock, in fact, it does not pass so many things to the recipient, the warlock just passes a false keyword, for example, after passing the information that you see a tree, then how tall the remaining tree grows, what kind of tree, how the leaves and so on are all imagined by the recipient himself.

Therefore, what Su Weimin has to do is to accurately and effectively transmit these keywords to the user through an electromagnetic magic device.

This is accurate and effective as it is easy to say, but it is actually quite difficult, in what order and at what pace are the keywords delivered? What is the process and algorithm of real-world restoration and extraction of keywords? Finally, there is the need to interact according to the user's mind, and the difficulty in this is definitely quite amazing.

Fang Shi has long known their research direction, in fact, this research plan Xing Yutong will naturally report to Fang Shi to apply, Fang Shi also supports this direction, and it is precisely because Fang Shi knows that he also knows that Su Weimin and Xing Yutong still have a long way to go if they want to make a breakthrough.

However, when Fang Shi saw the humble picture on the screen, he was still very shocked.

The talents of these two people can definitely make most people envious and jealous, Fang Shi couldn't help but glance at Academician Yuan, this old man smiled very happily, after all, the two young people who created this miracle were both his students.

"How? Isn't it amazing? ”

Academician Yuan asked triumphantly, the expression on Su Weimin's face was also very proud, and Xing Yutong was a little uncertain, and at the same time full of expectations, like a child waiting for her elders to evaluate her works, of course, she is indeed still a child.

"Yes, it's really amazing, I didn't expect you to be able to do this in such a short time, especially this real-life restoration and extraction process, which is definitely eye-catching, no, surprised."

Su Weimin laughed, and Xing Yutong's little face also bloomed with a sweet smile, and that happy appearance made everyone around feel that they were also happy.

There are two running puppies on the screen, but these two puppies are not the same, one is a white pug, the other is a wolf dog with a larger physique, these two virtual realities, in fact, there are two people who control zhì separately, these two people are also controlling a dog in virtual reality, running according to Su Weimin's instructions, turning and jumping and other actions, although the details are completely different, but the whole process is quite smooth.

Academician Yuan laughed for a while, and then said to Su Weimin: "You can continue." ”

Su Weimin nodded, and typed wildly on the keyboard with a smile, the instructions issued this time were more detailed.

"The control target is revoked, and a new target is established, this is a small black and white Dalmatian dog with a height of 30 centimeters, a body length of 60 centimeters, and a tail of about 20 centimeters."

Su Weimin sent the order out very chicly, and then on the screen in front of Fang Shi's eyes, two Dalmatians appeared one after another, although the two Dalmatians have looked quite similar, but they can still see obvious differences, at least, the location of the spots is different.

Fang Shi raised his eyebrows and praised with a smile: "Yes, this is already completely comparable to the clever illusion spell." ”

Su Weimin smiled and said, "Master Fang, don't be surprised so soon, the show has just begun." ”

Next, the line in the middle of the screen disappeared, the screen pulled a long view, and the two dogs stood face to face in an environment, Fang Shi's eyes shrank, and he looked at Xing Yutong in surprise, Xing Yutong raised his eyebrows proudly, and nodded lightly at Fang Shi.

Fang Shi turned his head to look at the screen, and then the two dogs gradually ran from slow to fast, the two dogs got closer and closer, and then violently bit together, at first the movements were quite stiff and slow, it looked like slow motion, but the situation was quickly improved, Fang Shi knew that this was because the two real people were getting familiar with this interaction.

However, the action of the two dogs biting and fighting has never been able to reach the fierce and agile Cheng dù in reality, which may be the bottleneck of the system or the bottleneck of the real person.

"Is this a system limitation or a human factor?"

Su Weimin seemed to know very well what Fang Shi wanted to ask, and turned his head and replied: "It's a system factor, people's thinking speed is very fast, in the virtual world, people should be more agile than animals in reality, and now this kind of bottleneck is because our computing speed can't keep up." ”

"Compute speed?"

This time, it was Xing Yutong who replied: "Elder, it is the bottleneck of keyword extraction, we need a lot of calculations to accurately extract an action into keywords and accurately send them to the opposite side." ”

Fang Shi was stunned for a moment: "Extract keywords, you mean, you extract this dog's actions into keywords, and then send them to the device of the opposite manipulator, and then extract the keywords from the actions of the other dog, and send them to the other manipulator?" ”

Xing Yutong nodded: "Yes, is there a problem?" ”

Fang Shi suddenly laughed: "Didn't you think about directly connecting the thoughts and feelings of these two people? In fact, the two people who are fighting don't need to know what the two dogs are doing. Only the bystander needs to know, so you need to extract the keywords and pass on the target to the bystander, not the two people who control the dog. ”

Fang Shi's reasoning is actually very simple, just like playing blind chess, the real need to look at the chessboard is actually the onlookers, and the two sides of the chess game do not need the chessboard at all, the chessboard is in their respective minds. (To be continued......)
