At 2: on June 2nd, Huawei HarmonyOS 2 and Huawei's new product launch conference were held as scheduled. At the press conference, the highly anticipated official version of HarmonyOS 2 was released, which means that HarmonyOS, which has been dormant for many years and devoted to research, has officially arrived!
in addition, Huawei has also released a number of new products equipped with HarmonyOS 2, such as the new version of HUAWEI Mate4 series, HUAWEI WATCH
, Huawei's annual flagship smart watch, and Huawei MatePad Pro, a new generation of semi-open wireless Bluetooth headset HUAWEI FreeBuds 4, high-end displays HUAWEI MateView and HUAWEI MateView GT are also officially available.
At the Huawei Developers Conference in 219, the mystery of HarmonyOS was unveiled for the first time. In the following year, HarmonyOS did not publicize itself, but kept a low profile, constantly improved its ecology, and devoted itself to studying in the days when people were out of sight. One year later, at the Huawei Developers Conference 22, HarmonyOS 2. made a stunning appearance, with a brand-new upgrade from capability, open source and the implementation of Huawei's "1+8+N" strategy.
According to Yu Chengdong, managing director and CEO of Huawei's consumer business, and Wang Chenglu, president of Huawei's consumer business software department, HarmonyOS 2. will be open to different devices including mobile phones, watches, smart screens and motorcycles in the future, and the "+"in Huawei's "1+8+N" strategy finally has the best cross-platform system support.
on may 25th, Weibo, the official official of Huawei EMUI, released a Weibo, announcing its official name change to HarmonyOS. Subsequently, Huawei EMUI official WeChat and Weibo officially put on new avatars related to HarmonyOS, announcing the arrival of HarmonyOS.
Tonight, HarmonyOS 2 officially came out, what amazing capabilities did it bring? Let's take a look.
HarmonyOS 2 was officially launched, and everything in life is unified.
The first appearance was made by Yu Chengdong, managing director of Huawei and CEO of consumer business. He said that a long-term strategy of Huawei's consumer business in the next decade is a full-scenario smart life strategy, focusing on five scenarios to create a user experience: smart home, smart office, smart travel, sports health, and audio-visual entertainment.
Today, we have entered an era in which everything is interconnected and everything is intelligent. But in this era, the sense of experience is very problematic: the connection is complicated, the control is complicated, and the experience is divided. In the IoT era, excellent connectivity has become a necessity, and this ability requires higher operating systems and is very fragmented.
HarmonyOS is an operating system that can support multiple devices and hardware. It can be installed on Huawei products and a wide range of IoT devices, even cameras, household appliances, sockets, desk lamps and so on. In the era of all things intelligence, HarmonyOS 2 provides the most widely supported operating system, with all things in life, All as one, One as all.
Dr. Wang Chenglu, President of Huawei's Consumer Business Software Department, followed closely by the introduction of HarmonyOS 2. He said that HarmonyOS adopted the whole station decoupling architecture from the beginning of its design five years ago, aiming to "meet the requirements of all sizes with one set of code". In the era of Internet of Everything, the connection of devices is very important, otherwise the Internet of Everything would be impossible. HarmonyOS creatively puts forward distributed technology, which connects various independent devices with soft bus. Soft bus is like a highway connecting various devices, and consumers can assemble the required devices by themselves according to their needs. No matter how many devices are connected together, HarmonyOS 2 must make it as simple for consumers as using one device.
Subsequently, Wang Chenglu formally introduced several functional and technical changes brought by HarmonyOS 2 installed on Huawei smartphones.
1. Three centers: control center, service center and notification center
Control center includes three modules: broadcast control center, quick switch and super terminal. So that consumers can easily control the local module and other devices connected to the local machine, and easily form a super terminal. It displays the status, switches and so on of all the third-party devices connected with the mobile phone in a unified control center in the form of cards. Consumers can view and control the status of all the third-party devices connected with the mobile phone in real time through a unified entrance, and can complete the connection between devices by simply dragging and dragging, abandoning the cumbersome multi-terminal operation mode in the past.
Service center: the service center is the negative screen of the original Huawei EMUI system. In HarmonyOS 2, more fast Applications form atomic components, and the corresponding functions can be operated more quickly without downloading the app.
the service center is the negative screen of the original EMUI system. now, in the HarmonyOS system, more fast Applications form atomic components, which can realize the operation of corresponding functions more quickly without downloading the app.
notification center: notification center and control center actually split the slide status bar in the original Android system into two parts. The notification center displays messages such as App and mobile phone.
2. Distributed soft bus technology allows users to assemble their own hardware
The biggest difference between HarmonyOS and Android is that HarmonyOS has a distributed bus, which is also the core of Harmony OS to realize the concept of "super terminal". Devices equipped with HarmonyOS can combine with each other, learn from each other's strong points and realize a new operating experience in the era of Internet of Everything.
For example, when a mobile phone wants to be a multiple camera, all the cameras of drones, motion cameras or other devices are linked with the mobile phone through a soft bus, and the mobile phone can control other cameras according to its own needs, just like scheduling the local camera, to form a super terminal in multiple camera. Super terminals can also be formed between mobile phones, computers and tablets. Although the PC is running Windows operating system and the mobile phone is HarmonyOS, as long as the distributed plug-in of HarmonyOS is installed on the PC, the file managers of the two will communicate with each other, and it will be very easy for them to call each other's contents and materials. For example, I found a good recipe. After putting the ingredients into the oven equipped with HarmonyOS system through the proportion of ingredients, I can make delicious food with a single click. Let the equipment no longer be a cold equipment, but also have the intimate service of temperature. Based on the distributed ability of HarmonyOS, consumers can assemble scene-based operation terminals at will according to their own needs, which has endless imagination space.
This is the concept of HyperTerminal. Users can use HyperTerminal to connect all devices equipped with HarmonyOS. Although it is easy to operate, it actually needs very strong technical support to realize these functions.
3. Short clock reference and anti-interference algorithm
When the connection becomes simple, the seamless flow between terminal devices is also one of the secret weapons of HarmonyOS 2. For example, when listening to songs on a mobile phone, you can push the songs in the mobile phone to the living room stereo and play them without feeling the interference and delay of the channel. Seamless flow between devices benefits from the soft clock reference and anti-interference algorithm of HarmonyOS 2 core, which mainly solves the problem of smooth synchronization and switching of audio and video.
The synchronization of soft clock makes three devices connected together to form a super terminal, * * * all abide by a clock reference; The anti-jamming algorithm can ensure the common interference caused by wireless transmission. Once there is too much interference, it will bring jitter, delay and packet loss. The anti-jamming algorithm must ensure that the interference of wireless channels in this scene is reduced to a tolerable range. Only by using these two technologies can we ensure the synchronization of picture and sound when the terminal switches, which is a technological breakthrough behind bringing convenience to users.
4. Atomization service
Wang Chenglu said that he hopes to use cards as a unified carrier of atomization service and a unified communication language among all HarmonyOS devices. Card is the carrier of atomized services, which can be easily obtained and shared in the service center, without downloading and installing, and all kinds of services can be obtained in one step. As the carrier and language of unified interaction between HarmonyOS ecological devices, the services will go wherever the card goes.
behind the atomized service lies the service form of "one-time development, multi-terminal deployment and cross-terminal circulation". For developers, when developing applications, they only need to write logic code once based on HarmonyOS 2, and then they can be deployed on various HarmonyOS terminals, which greatly reduces the development cost.
Performance is improved in an all-round way, and privacy is guaranteed
Wang Chenglu said that performance is an area that Huawei has been very focused on. The fluency of the new HarmonyOS 2 system has been greatly improved compared with the previous generation EMUI. After 36 months of use, the mobile phone still has a reading and writing speed close to that of the new mobile phone, even though the remaining space is extremely small.
HarmonyOS 2 optimizes the protection ability of background applications, making tasks online for a long time. Even if more applications are used, the state can be restored, and the information you see when you leave can be read when you come back. For example, when online shopping, you can reply to WeChat messages temporarily, open the search App to check the information, and when you return to the shopping App, you can directly return to the last browsing interface. In addition, HarmonyOS 2 can also make the game play longer: play "Peace Elite" with Mate 4 Pro equipped with HarmonyOS 2, and the battery life can reach 5.1 hours.
There are two important technical upgrades behind this:
1. Technical optimization of kernel layer, hardware abstraction layer, ROM layer, framework, etc.
According to Huawei's statistics, after about 2% users have used their mobile phones for 36 months, the ROM storage space of this machine has almost reached the limit, and the system will become very slow at this time. Users will generate a large amount of data in every step of operating the mobile phone, and these data are randomly read into the local storage space. Once the speed of reading the memory is affected, the experience of using the mobile phone will become very bad. After testing, when HarmonyOS 2 system is almost full, the aging degree of sequential reading, sequential writing, random reading and random writing is greatly reduced, that is to say, users who use HarmonyOS system can still use it very smoothly even if the mobile phone space is close to full capacity.
2. Huawei's self-developed full-set graphics stack
The Harmony OS 2 system has completely used Huawei's self-developed full-set graphics stack, and there are several technical innovations:
(1) The technical computing scheduling is put into the system, and the rendering of the whole graphics is no longer only dependent on the GPU, but the GPU and CPU can jointly do intelligent scheduling and rendering;
(2) separate the rendering logic and the business processing logic, and separate the rendering logic from the business logic;
(3) No more repeated drawing, which greatly reduces the load of video processing.
when these technologies are added up, users can operate and sell more smoothly and have a longer battery life. Here, Wang Chenglu gives an example: compared with the latest Apple mobile phone, playing a heavy game on Apple mobile phone lasts for 3.9 hours, and playing on Huawei mobile phone can last for 5.1 hours.
On the other hand, new actions have been taken in the consumer privacy and safety section. In order to ensure the safety of every device in the whole scene, and the safety of every data storage, transmission and use, multi-device collaborative identity authentication is started, which can be unlocked only through the double insurance of face recognition of mobile phone and watch connection. At the same time, HarmonyOS provides classified management of users' data and classified protection of devices, and sets a security threshold for super terminals: only devices that meet the security level requirements can access the data of the corresponding security level, so that users can safely use multi-device interconnection. Take unlocking a mobile phone as an example. When a user turns on collaborative authentication of multiple devices, if the watch and the user's face information are authenticated at the same time, the reliability level will be much higher than today's single-dimensional level.
Wang Chenglu said that the brand-new HarmonyOS is the first distribution based on the Open Atomic Open Foundation, and OpenHarmony is an open source project in an open community. Only by doing the ecology of HarmonyOS in an open way can it be open, and everyone is encouraged to do distributions and products in various fields based on the open community.
ecological vanguard array, all new products in the whole scene are equipped with HarmonyOS 2
After introducing HarmonyOS 2, a series of new products are followed.
Huawei WATCH 3, the first HarmonyOS product brought by COO He Gang of Huawei's consumer business.
1. Huawei WATCH 3 Series
