Almost everyone knows, "how many steps does it take to put an elephant in the refrigerator? But no one cares, because we don't have elephants.
However, people who are reading this article almost have to face the problem of "how many steps does it take to transfer mobile phone files to the computer?"? Because we have mobile phone files, and all of them need to be transferred to the computer.
Ideally, the answer to both questions is the same:
It really only takes three steps to put an elephant in the refrigerator
In most cases, we have more trouble transferring files than we think:
Open the wechat of the mobile phone, find the file transfer assistant in it, select the file of the mobile phone, send the file to the file transfer assistant, open the wechat of the computer, right-click in the file transfer assistant to transfer the file to the local computer.
Of course, there are many other ways to transfer mobile phone files to the computer, such as dual port U disk, such as network disk transfer, and Bluetooth transmission, but in the end, the steps are cumbersome, which requires continuous switching and operation between the mobile phone and the computer.
The network has drawn into the distance between you and me, but even if you stack your mobile phone and computer together, the files inside are still quite different.
In short, the "multi screen collaboration" function, which is continuously upgraded from the "one touch" small function, has become an indispensable killer function in Huawei's smart ecological experience.
The original purpose of the "one touch transfer" function is to solve the problem of "how many steps does it take to transfer mobile phone files to the computer?"? On this issue, the original "one touch transmission" and the current "multi screen cooperation" realized the operation of "opening the refrigerator door, putting the elephant into the refrigerator, and closing the refrigerator door".
In Huawei's newly released Huawei matebook 13 2021, we can repeat this three-step operation.
Keep the Bluetooth and Internet switch of mobile phone and computer on, and then you can easily put the elephant into the refrigerator
If the three-step transmission is not fast enough, then double-click the mobile phone window file on the PC, you can directly call word to modify. All changes will be synchronized to the mobile phone document at any time, and the transmission becomes more invisible.
Of course, the above transfer file demonstration is not new for Huawei ecological users. What you are interested in must be the new products just released.
Huawei's latest Huawei mate Book 13 2021 uses a 13 inch 2K resolution full screen, with a 3:2 screen ratio, so that the screen of the same size can display more pictures.
Huawei's matebook 13 2021 is equipped with high-precision 10 point touch as standard. It can not only cooperate with multi screen cooperation to realize more convenient ecological interconnection experience, but also add a variety of gesture touch operations to realize shortcut operations such as "three finger down screen capture".
Together with the new Wi Fi 6 network protocol, you can enjoy a more stable and faster network connection experience with a large band of broadband when you use it with a new generation of Wi Fi 6 router.
The improvement and support of the hardware performance is actually to make users closer to the ideal "intelligent office".
Shut the elephant in the fridge and leave the elephant alone?
In fact, from "one touch transmission" to "multi screen collaboration", there have been several iterations. Now the "multi screen collaboration" function that we can use in Huawei's new matebook series is far more than file transfer.
It can be said that file transfer is a requirement scenario of high frequency rigid demand in the working scenario, but there are other similar scenarios in the working scenario that need to be optimized by technology.
It's like we have to think about the things behind the elephant after we shut the elephant in the refrigerator. Shutting the elephant in is not the end of the matter. The end of the matter is "smart office".
With the development of smart devices, our office is no longer limited to the desk. When we are on business, we use our mobile phones to record the key points of the meeting, the fleeting inspiration in the coffee shop, and the important information exchanged with customers. Mobile phones often carry the task of recording and saving work materials.
Instead of dealing with these various content information on the stretched mobile phone screen, we might as well use the hardware advantages of PC to complete more efficient work output.
The mobile phone gently touches the notebook sensor area to connect "multi screen collaboration", which can open three mobile phone windows at the same time to complete the work collaboration. While listening to the conference recording, you can tap down the key points of the meeting, drag and drop important ppt photos into the document, and a meeting record can be easily completed.
There is no need to switch back and forth between different devices and different interfaces. Some things should be so simple.
The content crossover between multiple devices can not only improve the work efficiency, but also bring more convenience in daily life.
If you want to order a takeout at lunch time and are worried about collecting wool for the takeout platform, you can open two takeout softwares at the same time to compare prices. You can know who is more favorable by comparing all kinds of takeout, red envelopes and coupons, and you won't spend more money.
The same is true of online shopping. Nowadays, shopping on mobile phones has become a shopping habit of more and more people. Shopping platforms set up many coupons that can only be enjoyed by mobile terminals, and the discount price is often quite low. With the help of multi screen collaboration, Jingdong, tmall and Taobao can be opened at the same time for price comparison. It is a wise choice for consumers in the new era to place an order after comparing three stores.
The reason why "multi screen collaboration" can realize the interconnection between PC and mobile phone, thus bringing users a more intelligent lifestyle is that there are many invisible technical indicators behind it.
For example, when you swipe a short video on a PC, whether it's sliding up and down or playing video, it's no different from the operation on the mobile phone, and this operation is synchronized in time. When you slide on the mobile phone or PC, the other end will respond to the operation in time.
In order to achieve such undifferentiated synchronization, we need to control the display delay and audio-visual synchronization delay low enough. Huawei can control the display delay within 50 ms (industry average > 100 ms), and the audio-visual synchronization delay can be less than 200 ms, which can almost eliminate the sense of delay brought by wireless transmission.
Data transmission should not only be fast, but also be stable enough. By deeply optimizing the stability of transmission protocol (Huawei has its own developed protocol, which is obviously ahead of others), Huawei makes the connection success rate between devices higher. After testing, the connection success rate of multi screen collaboration is more than 99%.
"Multi screen collaboration" relies on Wi Fi P2P high-speed transmission technology. The maximum transmission speed can reach 60MB / s, and the bandwidth is large enough to allow 1080p resolution and 60 FPS frame rate high-quality transmission of mobile phone images, making it no different from mobile phones in terms of sliding or playing videos on PC.
Why is Huawei the only one to shut the elephant in the refrigerator?
Huawei's idea of multi screen collaboration was born in the laboratory as early as 2016. Planners have found a very interesting phenomenon: when users are working, they have eight hours a day to operate on the PC, while at the same time, they also have eight hours or more to spend on the mobile phone.
Users in two different device platforms have a very high frequency of use, but when file exchange occurs between devices, there is no good way to achieve convenient and efficient file transfer.
As a result, Huawei has invested a lot of resources to develop a "digital bridge" that can connect the two screens in combination with its advantages in the field of distributed database. It is the first time that the digital bridge has been opened to traffic.
From initially only supporting picture and video sharing, to adding the function of one touch transferring document and sharing clipboard, and then being able to open multiple mobile application windows on the computer at one time, multi screen collaboration is truly realized.
In the past two years, Huawei has been continuously expanding the capacity of this "digital bridge" and gradually realizing its vision of making the content of the two screens interoperable.
There are complex technical problems hidden in the simple desire, which is not simply to PC the mobile phone, or to simulate the mobile platform with PC, but involves the underlying intercommunication of the two systems.
How to share the capabilities of different hardware and ensure the security of distributed data will be the obstacle for Huawei to achieve efficient "multi screen cooperation".
For this reason, Huawei has established an independent transmission channel between the mobile phone and PC through the deep customization of the mobile phone and PC and the optimization of the system level, and adopted the self-developed minimalist protocol, which realizes the hardware call between the mobile phone and PC, greatly improves the success rate of the connection, and at the same time consumes less time.
Using PC to make low delay audio and video calls, and transmitting ultra clear video captured by mobile phone to PC at the bandwidth speed of 60MB / s, these cross platform operations can be realized on Huawei's matebook 13 2021.
Throughout the development of "multi screen collaboration", from the initial simple idea to the implementation of technical achievements, it has been experiencing iteration and upgrading, and constantly improving and enriching functions in order to bring users more intuitive operation experience.
With the increase of the number of hardware devices, the demand for content interaction between devices will be greater and greater. The "multi screen collaboration" of continuous optimization and upgrading is not only to connect the content of mobile phone and PC, but also to realize the collaborative integration of various intelligent devices, forming an invisible super interconnected terminal.
