Dreamwalker is a VR virtual reality system composed of a head-mounted display and multiple sets of sensors, head-mounted display technology has been around for decades, and the concept of VR has been hyped in the last century, but it quickly fell silent because of hardware limitations. As early as July 1995, Nintendo, one of the three giants of home game consoles, once launched a head-mounted portable game console called Virtual Wave Y, focusing on VR virtual reality games, intending to be the successor of the Game Wave Y game console.

However, this VB weighs nearly 900 grams after installing six AA5 batteries, so much so that when it was officially released, it had to add a bracket under the console, turning it into an inconvenient portable game console. Although the polarization spectrophotographic display system provided by Keio University can realize a 3D three-dimensional space composed of dotted line patterns, it is a red three-dimensional world, which is far inferior to the optical disc game console PS that Sony released a few months ago in terms of pure color.

Because the user experience of this product is very bad, the result is a decisive failure bird. In the same way, the once lively VR virtual reality concept is also subject to technical conditions, until recent years, with the improvement of the performance of a new generation of embedded processors and sensors, so that people have the technical basis for re-realizing the virtual reality, and the super plug-in of alien technology E7U is undoubtedly the fastest one.

As early as two years ago, when Pingxian was still in the second high school, Atletico Madrid made the first generation of head-mounted displays equipped with mobile phone motion sensors, and obtained good reviews from trial users Wei Wei and others. But it was rejected by Atletico Madrid himself, because the mobile phone motion sensor he used at that time was only the most basic kind of gravity sensor used to identify the horizontal and vertical screens of the mobile phone screen, and the sensitivity was not high, which led to problems with the recognition accuracy of the head-mounted display, and the display resolution was not satisfactory to him.

It wasn't until he started to build a quadcopter and came into contact with more and more professional sensors with higher indicators that the problem of action recognition accuracy was solved. The flight control module of the bee drone is used on the Dreamwalker eye patch, which can accurately identify the rotation, pitch and tilt of the player's head in combination with a variety of motion sensors, and after sending it to the controller, the display system, sound system and character motion control system can be adjusted in combination with the head movement parameters, which can greatly improve the player's viewing/game experience.

The laser measurement system equipped on the Dreamwalker omnidirectional treadmill can recognize the player's body and limb movements, but when the player's arm is stretched flat, the hand will be out of the laser radiation range, so the Dreamwalker glove is specially introduced, and the finger palm and wrist movement data are obtained through the pressure sensors on these two gloves.

The Dreamwalker playset includes three core components: an eye mask, gloves, and an omnidirectional treadmill, as well as accessories such as plastic models of swords, guns, sticks, bows, and arrows. However, even if you don't use an official model weapon, wearing the Dream Walker Glove to simulate the action of holding, swinging, and pulling the trigger with your bare hand can still control the weapon props in the game normally, but using the official attachment can provide a better grip, a sense of weight, and possible force feedback. Of course, model collectors can use their own collections to fight, just log it into the system, set the weight, and the length, width and height dimensions.

In addition, there is a special customized version of the Dream Walker Mask, which has an extra mask with a pressure sensor under the eye mask, which can be used to obtain the movement data of the player's face and mouth, which can be used by some special games to collect the player's smile and mouth opening movement, but because it is too ugly, it is not shown this time.

Because it is a development version, the eye mask and gloves are finally connected to the controller behind the waist through a cable fixed to the outside of the clothing, and the controller communicates with the treadmill ring ring close to the waist through light signals. Atletico Madrid's statement that the omnidirectional treadmill is just a supporting peripherals is actually a bit derogatory to it, because this "treadmill" is actually a powerful gaming PC, and the world of VR virtual reality runs on the "treadmill".

Ten minutes later, the five beta players lifted the Dream Walker blindfold from their faces with reluctance and reluctance, as the device ran out of power. The staff waiting on the side opened the protective ring on the waist of the treadmill and helped them out and walked to the backstage.

As soon as they left the omnidirectional treadmill, the trial players waiting behind them couldn't wait to walk in, and some people almost slipped because they stepped on the edge of a foot, but fortunately, the closer they got to the bottom of the concave surface, the greater the friction resistance, coupled with the timely blocking effect of the waist protective ring, they finally did not slip.

"Our staff will take the recycled Dreamwalker blindfolds and gloves backstage for routine sanitization, and then replace them with new rechargeable batteries and bring them back up. "At the moment, the battery we use is on the small side, which can only support more than 10 minutes of gameplay. In the future, the official version will provide an external battery interface and an external power interface, which can be attached to a larger capacity battery, or even directly connected to a treadmill or home socket with a low-voltage DC cable, and users can determine the power supply mode according to various usage scenarios. However, our advice is to keep the intense game to 10 to 30 minutes or less, and the virtual tour and 3D live action movie can be a little longer, but it's best not to take a short break for an hour. But you don't have to take off the eye patch, just start the eye protection program built into the eye mask, and it will play soothing and beautiful scenery images, which can help players soothe their emotions, effectively relieve eye fatigue, and prevent visual damage. ”

"Even so, we recommend not wearing the Dreamwalker Blindfold for long periods of time, as this display with only two displays in total darkness is not a very suitable physiology for the human eye, and our medical experts warn that prolonged use may damage vision. However, Atletico changed his words, "Fortunately, according to our tests, the continuous use time is less than 1 hour, and the cumulative use of the daily use is not more than 8 hours, and the reasonable use of eye care procedures will not damage the eyesight." ”

As a reporter present, Meng Bin got the opportunity to try out the Dream Walker blindfold in Atletico Madrid's hand after expressing his interest, although it was a little regrettable that he could not move at will without an omnidirectional treadmill. But after putting on the blindfold, Meng Bin was still shocked by what he saw.

Using sensor technology, bees can be said to have greatly revolutionized the experience of using stereo headsets and stereo headphones! Meng Bin found that when he felt a sound behind him, he turned his head back and looked back, and the sound would turn from behind him to the front with his head.5. The sound coming out of the 1-channel stereo headphones automatically changes direction according to the direction of his head, which greatly enhances the sense of space and direction.

When he turned his head and saw that the one running behind him was a vicious wolf that pounced on it with a cold light shining on its teeth, although he knew that there were many people standing next to him in the CJ venue at the moment, Meng Bin was so frightened that he screamed "ah", but fortunately, the sound was not loud and it didn't last long, so he didn't make a fool of himself.

It's not that Meng Bin quickly passed the will test of fear, it's really that the wolf's running speed is too fast, as soon as he saw it clearly, he couldn't help but exclaim, and the wolf pounced on him, and then nothing happened......

"Alas!" Meng Bin couldn't help but sigh, but there was a slight regret in his heart.

People are like this, when they see the wolf pounce on, most people will subconsciously because of the fear of carnivores in the genes and stimulate a large amount of adrenaline secretion, muscle tension and sweating, but when the process is quickly over and disappears, it is found that the original world is breezy, many people will feel sorry for the loss, and feel not exciting enough.

"Hungry wolf pounce" seems to be just an appetizer, or rather, a dismount, and after scaring people all at once, the world that they see and hear becomes peaceful and beautiful again. Because there is no omnidirectional treadmill, Meng Bin must move on the booth in order to make the world in his eyes move accordingly, in the audience it seems that this reporter is scurrying around the booth at the moment, but the strange thing is that he did not cower like a blind man who suddenly lost his sight and held it, the other people on the booth and the five omnidirectional treadmills were deftly avoided, as if he could still see the outside world while wearing an eye patch.

This is the bee "cheating", although the laser measurement system on the omnidirectional treadmill is oriented inward, used to quickly measure the user's movements, but for the laser signal reflected back from the surrounding environment, the system still has a certain ability to recognize. Although it is not possible to accurately identify the angle of the player's calf bend due to the distance and orientation, it is not a problem to recognize the surrounding wall pillars and the human body. These spatial measurements are shared by several devices, and the game PC that provides the video signal to Meng Bin's head also receives this signal and adds it to the construction of the virtual reality scene, so that the size and position of the obstacles in reality are restored to the world that Meng Bin sees. So although he couldn't see who was blocking him, he could see that there was an obstacle in front of him and should turn, Meng Bin was a little cautious at first, but after testing a few times to make sure that he wouldn't touch someone, his movements were obviously bold, if he hadn't learned light skills, maybe he would have been running all over the field.

When the battery ran out and he had to take off the blindfold, Meng Bin gasped and wondered, how could he "talk about the old man and be crazy with his youth" and run around for more than ten minutes under the blazing gaze of hundreds of people?

"That's the beauty of an immersive experience, where you unconsciously get deeper into the character's point of view, and your body reacts more intensely. Atletico, who sat across from him, explained.

In fact, after starting to line up for a trial, his press conference ended, and after handing over the scene to his subordinates, Atletico Madrid and Meng Bin moved to the business district to conduct an interview that had been scheduled for a long time.

Retracting the interview outline handed back by Atletico Madrid, Meng Bin looked down and saw that he had a number in his heart. This interview outline was something he had just thought about on the road, and as soon as he sat down in the business district, he immediately wrote it out by hand, because the appearance of the dreamwalker disrupted his plan, and the interview outline he had prepared was useless.

"Yes, when I first saw that wolf just now, I was so scared that I screamed, I don't know if I can hear it outside?" Meng Bin smiled and talked about his own troubles to pull the relationship.

"No, it's a bit noisy," Atletico shook their heads in denial.

After a few greetings, Meng Bin got to the point: "I see that this set of products seems to have a high degree of completion, Mr. Ma, do you have any promotion and sales plans for the next step?"

"In the next step, we do not plan to directly advertise and promote agents on a large scale, but plan to rely on more than 30 space station Internet cafes under our Bee Group and hundreds of Bee Sure stores to conduct a period of offline large-scale free trial activities. After all, this product is just like I said before, the effect of seeing the demonstration and listening to others is far less than one-tenth of what I feel in person, so the best way to let more people try it out and then use their word-of-mouth to gain recognition. ”

"Space station Internet café I know, the only real diskless and hostless Internet café, but what is the sure store?"

"It is the hardware product store that Bee will build in major consumer cities, mainly selling Bee mobile phones and other Bee hardware products. SURE is the abbreviation of the four major businesses of sale, upgrade, recovery, and entertainment. ”

"Originally, we thought about the name of a mobile phone factory store, a mobile phone workshop, a mobile phone wonderful house and other stores, but the names of the factory and the workshop did not feel very good, and there was a bit of an outdated impression that the factory and the wonderful house were too childish, so in the end, we had to choose the name sure store. In addition, the word "sure" is not as familiar to many people in Japan as OK, even if you have not studied English, but it is also a very recognizable word. After all, many people have done multiple-choice or fill-in-the-blank questions to identify the usage of "certain", "certainly", "ofcour" colors, "sure", and "surely" when they were in school. Bee named its store SURE store is to emphasize a one-stop solution to all problems and needs, safe, secure, secure and reliable feeling, and at the same time use English words to make the store name image will have a younger and international effect, we also specially registered the SURE store logo in a number of major countries and regions, and will be used as a unified logo for bee offline services in the future. Of course, according to the "Regulations on the Administration of Enterprise Name Registration", only Chinese characters can be used to name names, and the official name on the domestic business license is Shuerdian.

Meng Bin is not surprised by the four major businesses of the bee sure store, in fact, the vast majority of small mobile phone stores are both doing s sales and e-entertainment downloads. Because many people have no experience in using computers, they are not very good at downloading songs, wallpapers and videos from mobile phone TF cards, so they will seek help from mobile phone stores, and slowly open up a new type of business for mobile phone stores, which is to help customers download songs and videos.

However, although this business is convenient for consumers and has also brought some income to mobile phone stores, it has great legal risks, and these songs, film and television resources are basically pirated, and some mobile phone store owners will also provide cyan audio and video download services in order to meet customer needs and solicit business, which has escalated from cracking down on illegal pornography to the level of anti-pornography, and the crime has been further deepened.

Therefore, Meng Bin feels that the addition of bees to this piece should also be very helpful in regulating this business and making it formalized and legalized.

After he raised his concerns about the copyright of entertainment downloads, Atletico said: "At present, the regulations on the right to use and reproduce digital music in China are still very vague, and it is indeed illegal to copy music and film and television content to others without authorization, and even if it needs to be done legally, it is still a question of which unit should pay the copyright fee." We already have a solution to this point, and we must not break the law anyway. ”

Atletico Madrid's solution to the problem of not breaking the law is actually very simple, that is, they are not mixed in, the bee sure store will provide mobile phone users with some specially customized touch screen computers as "download machines", users can connect with a data cable, they can directly search for resources such as movies and television songs and pictures on the Internet, and download them to the mobile phone with just one finger. The resources come from a third party, and the operation is carried out by the user independently, so as to avoid the legal risks of the bee itself. In fact, this trick is now used by many music and video websites, and Bee has just moved this method offline.

"So what's going on with the upcycling and recycling business of your SURE shop, can you tell us about it?"

"Upgrading is to help users replace the parts of the mobile phone, from the shell to the processor chip, and then recycle the waste parts. This prevents users from spending huge sums of money on a new phone just for a look or function, and at the same time, such an upcycling and recycling mechanism can reduce waste and protect our planet. ”

"This should be hard to achieve, right? There are so many mobile phone models these days. ”

Atletico Madrid waved his hand, "This upcycling can only be operated for bee mobile phones, after all, our staff is not familiar with other models, isn't it? Each main function is basically integrated on a chip, and the function of the mobile phone can be upgraded by replacing the corresponding chip like a computer replacing a CPU chip memory graphics card. When designing the internal circuit of our bee mobile phone, we have designed our exclusive mobile phone chip interface with reference to the PC interface, and professionals can easily upgrade and replace the main components with the help of tools. ”

"Can it be like a DIY computer?"

"In the future, there may be modular real DIY phones, but at least not yet. There are only motherboards, CPUs, memory, graphics cards, hard disks, fans, and floppy drives and optical drives that are gradually losing their status, but for mobile phones, in addition to processor chips, there are GSM baseband chips, Bluetooth WiFi chips, power management chips, and a variety of sensors, many of which are millimeter-sized and need to use tweezers and magnifying glasses, so that ordinary users will be very worried about hand-assembling mobile phones.
