Chapter 400 There is a deep meaning in it!
"Virtual reality technology, also known as spiritual mirror technology or artificial environment technology, is a digital simulation technology that uses a variety of computer technology-based information technologies and other high-tech means to generate a human-like environment within a specific range. A realistic three-dimensional artificial virtual environment integrating vision, hearing, touch and smell, users can 'project' themselves into the environment through special equipment, and interact with the environment through virtual sensing devices."

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

"Virtual reality systems generally have three major characteristics: immersion, interactivity and conception. Immersion is the core of virtual reality technology, interactivity is the requirement, and conception is the purpose."

"These are just the most basic knowledge, and you don't need to explain it at all!" Lou Beifeng, who has a lot of research on virtual reality technology, thought that Lin Dong would talk about such profound knowledge, but he didn't expect him to talk about the most basic knowledge. I couldn’t help sniffing at the common sense, “Can you say something useful? We have created virtual training cabins and training equipment, how could we not even know this?”

As soon as Lou Beifeng finished speaking, a weak voice rang out: "Can you tell me about the three major characteristics?"

Lin Dong looked over, and it turned out to be a female researcher who was about the same age as Chen Qian. She raised her hand and asked, "We don't do much research on this, can you explain it to us in detail?"

It turns out that although Lou Beifeng is the person in charge of the project team and has the most knowledge about virtual reality technology, not everyone in this second research room has his ability.Except for the few researchers he brought with him, most of the others have little knowledge. Most of their understanding of virtual reality technology is self-taught, and some are from what Lou Beifeng heard, and they are not in those project teams. Just smattering.Now that someone is explaining it systematically, they naturally want to know more about it.

Someone asked for advice, and Lin Dongle gave a lecture: "Immersion, in fact, means that in the virtual environment provided by the virtual reality system, the experiencer does have the real feeling of 'visible, tangible, audible, and smellable'; and Interactivity means that 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 games played now, but more realistic."

"As for the conception, it means that users acquire new knowledge and experience in the virtual environment, form perceptual or rational knowledge, thus generate new thoughts and actions, and effectively improve the ability of thinking and action."

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

Lin Dong said with a smile: "The abacus is called the earliest computer, and it can also quickly perform large data calculations, but how different is the abacus from today's computers?"

An uproar!
Comparing Lou Beifeng's simulated training cabin to the real simulation cabin with an abacus and a computer, isn't this a bit too exaggerated?

Many people became aggrieved, especially those 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, the person involved, Lou Beifeng, was thoughtful.

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

"What I mean is just an example. In fact, the gap is not that big." Lin Dong ignored the others and continued to explain: "The general development trend of virtual reality technology has four stages. From the current popular virtual glasses, From more advanced virtual helmets to full-body virtual equipment, the final development is the virtual cabin or indoor three-dimensional virtual environment. The final development is a branch of two aspects, let’s not talk about it for now. And virtual glasses and virtual helmets are full-body The original version of the virtual equipment."

Lin Dong pointed to the simulated training cabin and said, "This looks like the final version, but I took a closer look just now, and it's actually a built-in version without complete full-body virtual equipment. That's why I said that."

When he said this, everyone suddenly realized that it was so!

"Under 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 these three senses, we can provide users with nutrition and be immersive. The feeling. The vision is mainly completed by the helmet display or virtual glasses, the auditory simulation system is composed of stereo receivers that transmit sound, and the tactile simulation system is composed of sensor data suits and data gloves. Through them, the eyes, ears, hands , joints and brains are connected to a virtual world created by a computer."

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

All the researchers present were accustomed to speaking with data. Although they were unwilling, they had to say that what Lin Dong said was true.

"This is the difference in technology." Lin Dong said with a smile: "The sensors are different, the codes are different, the software is different, and the results are naturally different. This is why your higher authority asked me to come and cooperate with you to create this simulation training The reason for the device. I think, if I don’t make it clear, I’m afraid there will still be troubles when we cooperate in the future!”

It was so!
Many people suddenly realized.Lin Dong spoke so contemptuously at the beginning, and later explained and "popularized science" so hard, and finally talked with the facts and data of the helmet and the virtual cabin, in order to spend less time in cooperation in the future, and avoid detours. Avoid people in the scientific research team despising him because of his youth, causing unpleasant cooperation.

This young man is really thoughtful!

Thinking of this, many people are relieved. After all, the helmet is indeed much more convenient to use than the virtual cabin. Whether it is the sensitivity of the sensor, the speed of data transmission, or even the comfort level, it is better than the simulated training cabin!
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 capable!

Even Lou Beifeng had to admit that Lin Dong was indeed good at virtual reality technology!
