How does Huawei put the “elephant in the refrigerator” and make the elephant bigger?

Almost everyone knows the question "How many steps does it take to put an elephant in the refrigerator?" But no one cares because we don't have an elephant.

But those who are reading this article almost have to face the question of "How many steps does it take to transfer mobile phone files to the computer?", because we have mobile phone files, and they all need to be uploaded to the computer.

Ideally, the answers to these two questions are the same:

  • Open the refrigerator door (mobile phone connected to computer)
  • Put the elephant in the refrigerator (select the phone file)
  • Close the refrigerator door (transfer files to the computer)

It really only takes three steps to shut the elephant in the refrigerator

In most cases, it is much more troublesome than expected to transfer files:

Open the mobile phone WeChat, find the file transfer assistant inside, select the phone file, send the file to the file transfer assistant, open the computer WeChat, right-click in the file transfer assistant to transfer the file to the 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 after all, the steps are complicated and require constant switching and operation between the mobile phone and the computer.

The Internet has drawn the distance between me and you, but even if the phone and computer are stacked together, the files inside are still very clear.

Now, entering the Huawei 1+8+N smart ecosystem, users who own Huawei laptops and Huawei mobile phones must be familiar with the "multi-screen collaboration" function.

Simply put, this "multi-screen collaboration" function, which has been continuously upgraded from the small function of "One Touch", has become an indispensable killer feature in Huawei's smart ecological experience.

The original intention of the "One Touch Transmission" function is to solve the problem of "How many steps do you need to transfer files from a mobile phone to a computer?" On this issue, the original "One Touch Transmission" and the current "Multi-screen Collaboration" The operation of "open the refrigerator door, put the elephant in the refrigerator, and close the refrigerator door" is realized.

On the Huawei MateBook 13 2021 that Huawei just released, we can once again reproduce this three-step operation.

Keep the Bluetooth and interconnection switches of your phone and computer on, and then you can easily put the "elephant in the refrigerator":

  • The phone is close to the touchpad
  • Select the required file
  • Drag and drop directly to the desktop

We have become accustomed to the computer language of copy, paste, and save as, but we have forgotten that the operation of "pick up and put down" is our instinctive habit. When virtual documents can also use drag-and-drop operations as instinct, the matter of transferring documents becomes no longer cumbersome.

If the three-step transmission is not fast enough, then double-click the phone window file on the PC to directly call Word to modify, and all changes will be synchronized to the phone document at any time, and the transmission becomes more invisible.

Of course, the above transmission file demonstration is not new to Huawei ecological users, and everyone must be interested in the new products that have just been released.

Huawei's latest Huawei MateBook 13 2021 model uses a 13-inch 2K resolution full screen, with a 3:2 screen ratio, allowing the screen to display more images under the same body size.

Huawei MateBook 13 2021 models are equipped with high-precision ten-point touch control as standard, which can not only cooperate with multiple screens to achieve a more convenient ecological interconnection experience, but also add a variety of gesture touch operations, such as "three-finger under-swipe screen capture" And other quick operations.

In addition, Huawei MateBook 13 2021 has updated the 11th generation Intel® Core ™ The processor has a performance increase of up to 35%, and it can be more handy when dealing with large-scale computing tasks or audio and video processing.

Also upgraded with the new Wi-Fi 6 network protocol, with a new generation of Wi-Fi 6 routers, you can enjoy a more stable and faster network connection experience brought by large bandwidth.

The improvement and support of these hardware performances are actually aimed at bringing users closer to the ideal "smart office."

Put the elephant in the refrigerator and leave it alone?

In fact, from "One Touch Transmission" to "Multi-screen Collaboration", there have been several iterations, and now we can use the "Multi-screen Collaboration" function on the new Huawei MateBook series more than just transferring files. Up.

It can be said that file transfer is a high-frequency and just-needed demand scene in the work scene, but there are other similar scenes in the work scene that need to be optimized by technology.

It's like after we put the elephant in the refrigerator, we have to consider the things behind the elephant. The end is not the end of the matter. The end of this matter is "smart office".

With the proliferation of smart devices, our office is no longer confined to desks. We use mobile phones to record the key points of meetings during business trips, record fleeting inspirations in coffee shops, and record important information communicated with customers. In many cases, mobile phones carry the task of recording and saving work materials.

Rather than dealing with such a wide range of content and information on a stretched mobile phone screen, it might as well use the hardware advantages of a PC to complete more efficient work output.

Touch the induction area of ​​the notebook to connect to the "multi-screen collaboration", you can open three mobile phone windows at the same time to complete the work collaboration, while listening to the meeting recording, tap the meeting points, drag and drop important PPT photos into the document, a meeting record It can be done easily.

There is no need to switch back and forth between different devices and different interfaces, some things should be so simple.

Content crossover between multiple devices can not only improve work efficiency, but also bring more convenience in daily life.

If you want to order a takeaway at lunch time, and you are worried about giving the takeaway platform back to the fleece, you can open two takeaway software at the same time to compare prices. All kinds of takeaways, red envelopes, and coupons will know who is more favorable and no longer spend more. Wrong money.

The same is true for online shopping. Nowadays, shopping on mobile phones has become a shopping habit for more and more people. For this reason, shopping platforms have set up many discount coupons that can only be enjoyed on mobile terminals, and the discount prices are often quite a lot. With the help of multi-screen collaboration,, Tmall and Taobao can be opened for price comparison at the same time. It is the wise choice for consumers in the new era to shop around and place an order.

The reason why "multi-screen collaboration" can realize the interconnection between PCs and mobile phones, thereby bringing users a smarter lifestyle, is because there are many invisible technical indicators behind it.

For example, when casting a short video on the PC, whether it is sliding up and down or playing the video is no different from the operation on the mobile phone, and this operation is synchronized in time, sliding on the mobile phone or PC, the other end will respond to the operation in time.

To achieve such indifferent synchronization, it is necessary to control the display delay and audio-visual synchronization delay to be low enough. Huawei can control the display delay within 50 milliseconds (the industry average level> 100 milliseconds). The synchronization delay can also be less than 200 milliseconds, which can almost eliminate the delay caused by wireless transmission.

Data transmission must not only be fast, but also stable enough. Huawei deeply optimizes the stability of the transmission protocol (Huawei has a protocol developed by itself, which is clearly ahead) to make the connection success rate between devices higher. After testing, the connection success rate of multi-screen collaboration is greater than 99%.

"Multi-screen collaboration" relies on Wi-Fi P2P high-speed transmission technology. The maximum transmission speed can reach 60MB/s. The bandwidth is large enough to allow mobile phone screens to be transmitted with high quality at 1080P resolution and 60 FPS frame rate, so that whether it is sliding on the PC Or playing a video, just like a mobile phone.

Why only Huawei put the elephant in the refrigerator?

Huawei's concept of multi-screen collaboration was actually born in the laboratory as early as 2016. The planners discovered a very interesting phenomenon: When users are working, they have 8 hours a day to operate on the PC, and at the same time, 8 hours or more are spent on the mobile phone.

Users have extremely high frequency of use on two completely different device platforms, but when file exchange between devices occurs, there is no good way to realize convenient and efficient file transfer.

Since then, Huawei has combined its own advantages in the field of distributed databases and invested a lot of resources to develop a "digital bridge" that can connect two screens. The launch of "One Touch Legend" is the first opening of this "digital bridge".

From the initial support only for sharing pictures and videos, to adding the functions of uploading documents and sharing the clipboard with one touch, to being able to open multiple mobile phone application windows on the computer at once, realizing multi-screen collaboration.

In the past two years, Huawei has continuously expanded the capacity of this "digital bridge" and gradually realized its vision of enabling the content of the two screens to communicate.

There are complex technical problems hidden in simple wishes. This is not just simply turning a mobile phone into a PC or using a PC to simulate a mobile platform, but involves the underlying interoperability of the two systems.

How to make the capabilities of different hardware mutually help and share, and ensure the security of distributed data, will be a hurdle that Huawei cannot avoid to achieve efficient "multi-screen collaboration".

To this end, Huawei has established an independent transmission channel between the mobile phone and the PC through in-depth customization of mobile phones and PCs and optimization of the system level, and adopted a self-developed minimalist protocol to implement hardware calls between mobile phones and PCs. It also greatly improves the success rate of the connection, and also takes less time.

Use the PC to make low-latency audio and video calls, and transfer the ultra-definition video shot by the mobile phone to the PC at a bandwidth speed of 60MB/s. These cross-platform operations can all be implemented on the Huawei MateBook 13 2021 model experienced this time.

Throughout the development of "multi-screen collaboration", from the initial simple idea to the landing of technical achievements, it has been undergoing iterations and upgrades. It has been continuously improved and enriched in order to bring users a more intuitive operating experience.

With the increase in the number of hardware devices, the demand for content interaction between devices will increase. The continuous optimization and upgrading of "multi-screen collaboration" is not only to connect the content of mobile phones and PCs, but also to enable various smart devices to achieve Collaborative integration to form an invisible super interconnected terminal.

In other words, the "multi-screen collaboration" that can be experienced at present is only part of its infinite possibilities. After the full ecological completion of Huawei's 1+8+N smart devices in the future, the "multi-screen collaboration" is far more than that.
