"Virtual reality technology, also known as mirror technology or artificial environment technology, is a kind of digital simulation technology, which uses a variety of information technology and other high-tech means based on computer technology to generate a realistic three-dimensional artificial virtual environment that can integrate people's vision, hearing, touch and smell within a specific range, and users can 'project' themselves into the environment through special equipment, and can interact with the environment through guò virtual sensing equipment."

Lin Dong touched the virtual training cabin and talked eloquently, and really began to "popularize" the "common sense" of virtual reality technology.

"Virtual reality systems generally have three main characteristics: immersion, interactivity, and conception. Immersion is at the heart of virtual reality, interactivity is the requirement, and imaginativeness is the goal. ”

"This is just the most basic knowledge, and you don't need to talk about it at all!" Lou Beifeng, who is very interested in virtual reality technology, originally thought that Lin Dong would say how profound knowledge he would, but he didn't expect what he said was the most basic common sense, and he couldn't help but scoff, "Can you say something useful?" We've all built virtual training pods and training gear, how can we not even know this? ”

As soon as Lou Beifeng's words fell, a weak voice sounded: "Can you talk about the three characteristics specifically?" ”

Lin Dong looked over and saw that it was a female researcher of the same age as Chen Qian, she raised her hand and asked, "We don't have much research on this, can you give us a detailed explanation?" ”

It turned out that although Lou Beifeng was the person in charge of the project team and had the most knowledge of virtual reality technology, not everyone in this second research room had his ability. Except for a few researchers he brought with him, most of the others are half-understood, most of them are self-taught, and some are what Lou Beifeng heard, not in those project teams, but only half-understood. Now that someone is systematically explaining, they naturally want to know more.

Someone asked for advice, Lin Dongle said: "Immersion, in fact, is that in the virtual environment provided by the virtual reality system, the experiencer does have the real feeling of 'seeing, touching, hearing, and smelling', and interactivity refers to the way the experiencer uses the behavior in daily life to communicate with people or objects in the virtual scene to produce a real interactive experience, which is similar to the game played now, but more realistic." ”

"As for imagination, it refers to the use of room to acquire new knowledge and experience in a virtual environment, to form perceptual or rational understanding, so as to generate new thoughts and actions, and effectively improve the ability to think and act."

After Lin Dong finished speaking, the female researcher raised her hand again and asked, "Since these three characteristics, in my opinion, this simulation training cabin developed by Researcher Lou has all of them?" So why do you still say that this is 'in vain'? ”

Lin Dong said with a smile: "The abacus is known as the earliest computer, and it can also quickly perform large number calculations, but compared with the current computer, how much is the difference between the abacus and the current computer?" ”

There was an uproar!

Comparing Lou Beifeng's simulation training cabin to a real simulation cabin to an abacus and a computer, this is a bit too exaggerated, right?

Many people became indignant, especially the people in the Lou Beifeng project team, who had a certain understanding of virtual technology, and were very dissatisfied with Lin Dong's analogy.

On the contrary, it was Lou Beifeng, the party concerned, who was thoughtful.

Lin Dong saw it in his eyes, and secretly felt that this person was not as arrogant as he thought just now, it seemed that at least the essence was not bad, and he knew how to reflect.

"I mean figuratively. In reality, the gap is not that big. Lin Dong ignored the others and continued to explain: "The general development trend of virtual reality technology is that there are four stages, from the current popular virtual glasses, to the more advanced virtual helmets, to the full-body virtual equipment, and finally to the development of virtual cabins or indoor three-dimensional virtual environments. The final development is a two-sided branch, which we will leave aside for the time being. The virtual glasses and virtual headsets, on the other hand, are the original versions of the full-body virtual equipment. ”

Lin Dong pointed to this simulation training cabin and said, "This looks like the final version, but I took a closer look just now and found that there is actually a built-in version that does not have a complete full-body virtual device." That's why it's said. ”

As soon as he said this, everyone suddenly realized that this was the case!

"In the current state of technology, the three-dimensional space built with virtual reality technology pays more attention to the user's visual, auditory and tactile experience." Lin Dong continued: "Through the three senses, these three senses come to give users the feeling of being immersed in nutrition. Vision is mainly done by helmet displays or virtual glasses, the auditory simulation system consists of a stereo receiver that transmits sound, and the tactile simulation system consists of a sensor's number of suits and a number of gloves. They connect the eyes, ears, hands, joints, and brains with the virtual world created by the computer. ”

Speaking of this, Lin Dong bent down and took out the Flying Wolf Helmet of the Changying Group from the virtual cabin, and then said: "If it is divided by level, this helmet we produce actually belongs to the second generation, and the full-body virtual equipment in this virtual cabin should be the third generation. But I think if you have experienced it, you will know that the realism and sensitivity of this helmet we produce are actually stronger than your three generations of full-body equipment, right? ”

The people present were all researchers, who were accustomed to speaking in terms of numbers, and although they were unwilling, they had to say that what Lin Dong said was true.

"That's the difference in technology." Lin Dong said with a smile: "The sensors are different, the coding is different, and the software is different, and the results obtained are naturally different. That's why your higher authorities asked me to come and work with you to create this simulation trainer. I think that if I don't make it clear, I'm afraid that there will still be trouble in cooperating in the future! ”

So that's it!

Many people suddenly realized. Lin Dong said so disdainfully at first, and then he took such a painstaking explanation and "popular science", and finally spoke with the fact of the helmet and the virtual cabin, in order to make less tongue and detours in cooperation in the future, and to avoid the people in the scientific research group from despising him because of his youth, causing unhappiness in cooperation.

This young man is really thoughtful!

Thinking of this, many people are relieved, after all, the helmet is indeed much more convenient than the virtual cabin, whether it is the sensitivity of the sensor, or the speed of the transmission of the number of jù, and even the comfort range is stronger than the simulation training cabin!

Originally, there were people who suspected that Lin Dong was not the real designer of the helmet, but now they basically believe that this Lin Dong is really level!

Even Lou Beifeng had to admit at this time that Lin Dong did have a hand in virtual reality technology! For mobile phone users, please visit wènhttp://mnet
