Wang Yufei paused when he said the fifth step, not because he was selling off, but because he seemed to have some trouble with the fifth step.

"The fifth step of silent police is actually somewhat controversial. Including whether this feature should be added, I also had some arguments with Weihua engineers at the time. However, it was decided to add this step, but this step is optional. ”

"This step is actually to ask for help from the mobile phones around you that also have brain-computer chips, that is, to send a request for help to countless ordinary people. ”

"The point of contention between me and engineers for China is that when people are threatened by their lives in extreme environments, asking for help from people they don't know around them can put ordinary people in a moral dilemma. and the possibility of creating opportunities for bandits. For example, in the case of a planned violent crime, this technology is used to detect whether the victim has the intention and intention to report to the police. ”

"But in the end, I decided to add this feature, but I also added restrictions to this feature. ”

"First of all, it's a two-way alarm function, which means that if you want to use this service, you have to join the crisis support program. This will be specifically noted in the use of the service. In other words, if you are in a crisis situation and want someone around you to help you in time, then you should also choose to passively receive these alerts. ”

Second, this function does not call for help based on the distance, but selectively calls for help to nearby mobile phones with the same function according to a specific algorithm. The algorithm for this judgment is multidimensional, and for various reasons, I will not elaborate on it. But I would like to state again that Huawei and Changxiang Technology have decided to set up a brain-computer chip for this function, and the purpose of the fund's existence is to help those ordinary people who receive distress signals and choose to help provide a certain degree of protection. Please refer to the official website for details. ”

In addition, in order to prevent false alarms and waste public resources of this silent alarm function to the greatest extent, we have also made some technical limitations on this function. For example, when the owner tries to activate this function, the brain-computer chip will make a simple judgment on the state of the owner at that time. The principle is that the brainwave signal when a person is extremely nervous and flustered in a crisis state will be significantly different from the brainwave signal when activating this function with a joking mentality. ”

This means that in a completely safe environment, the silent alarm function may not be triggered. However, in order to maximize the original meaning of this technology, and under the condition that our brain-computer chip technology is not mature enough, this silent alarm function can still be triggered in most cases. For example, in the case of rapid running, heart beating, various exciting sports and playing some exciting games in the playground, this alarm function may be successfully activated. ”

"But here I want to remind all consumers that the silent alarm function has added a user blacklist function, if you try to use this function with a fun mentality for no reason, and there are consequences, the first time this function will be closed for a week, the second time will be closed for a month, the third time will be closed for a year, and the fourth time will be directly sealed forever!"

"And I need to emphasize that it is the user's brainwave data signal that is permanently sealed. It's not as simple as changing your phone and applying for a new account. The brainwave signal characteristics of all products will leave a multi-dimensional feature code on the server. This pattern code can protect the information security of your device to the greatest extent, whether you change your account or have several similar mobile phones, but the pattern code will not change on the brainwave signal server. Therefore, for your safety and the safety of others, please use this feature with caution. ”

"Then some people will surely wonder, if I can't test it, how do I know if my P45 will really help me if I'm really in danger, and will there be something wrong with this feature?"

"It's actually very easy to solve, and in order to prevent this from happening, we designed a crisis test environment specifically for this purpose. That is to say, if users want to try our silent alarm function, and do not occupy public resources to really dial the alarm number, they can enter this crisis test environment to test. Next, I will demonstrate the workflow of the entire silent alarm function in a crisis test environment. ”

......

The voice fell, and Lu Yuxin walked up to the rostrum with a mobile phone.

Quietly stood at the other end of the rostrum.

Then Wang Yufei clicked on the brain-computer function module on the table again, this time it was different from the interactive interface before binding, and there was already an icon enabled for the microcomputer test environment in the most eye-catching position.

Wang Yufei clicked on the icon, and a dialog box popped up.

"Please enter a phone number instead of the 110 public police number. Please note that in order not to cause any trouble to others, please do not enter the phone number of unrelated people, as being reported may affect your brain computer credit score. ”

"As you have seen, the phone entered here will replace the 110 public police number, you can choose your second number, or say hello to a friend in advance, and then enter his number, I am using another mobile phone number prepared for Hua here. ”

After speaking, Wang Yufei stood there without moving, and the mobile phone automatically filled in a number.

Wang Yufei then spoke: "As you can see, after binding brainwaves, although we can't directly input complex Chinese character content, pure digital content can be basically entered without barriers in the brain-computer interaction mode. At the same time, in this mode, after the input is completed, we silently recite 1 three times in our mind, which means that we confirm that we have entered the next step, and silently recite 0 three times, which will go back to the previous step. ”

When the voice falls, the phone has entered the next step, prompting the user to set the number of the emergency contact.

This time it was faster than just now, about ten seconds, and the phone automatically filled in a different number.

Then automatically skip to the next step.

"Please set up a WeChat emergency contact. This function needs to wake up WeChat and read the list of WeChat users. ”

Soon WeChat was called, obviously a new application for WeChat, there were only a few people, Wang Yufei reached out and selected all the people on WeChat.

......

Wang Yufei was operating the mobile phone here, and Lu Yuxin didn't stop the movements in her hand, a total of five mobile phones were placed in a row by her, and all of them opened WeChat.

At the same time, the big screen behind the two began to switch again, and the screen of each mobile phone was projected on the big screen in real time.

"Okay, now that everything is ready, I'll turn off the screen of this phone now, put it in my pants pocket as usual, and enable the silent alarm function......"
