Shulou(Shulou.com)11/24 Report--

It is said that wireless is the trend of technology in the future, but many times the actual experience of wireless devices is often indescribable.

For example, when your game comes to a critical moment, you lose a good game because of the delay of the wireless mouse.

When you have a meeting, you have to connect wireless keyboard and mouse, headset and screen at the same time, but it makes you worry when you see so many USB transceivers.

For example, many mobile phones can cooperate with computers on multiple screens, but as soon as the network is congested or a little farther away, the collaborative picture will be very stuttered, very bad.

All the above pain points are seriously affecting the experience of human-computer interaction in the wireless era.

Of course, it is not that wireless is bad, but that the traditional wireless connection technologies such as Bluetooth and Wi-Fi will fall short in the face of more and more intelligent terminals and the extreme requirements of high-speed and low-delay human-computer interaction scenarios in the new era.

Obviously, we need new wireless technologies to make up for the limitations of Bluetooth, Wi-Fi and other new scenarios in the era of the Alliance of everything.

As a result, starglitter technology appeared.

Star flash (NearLink) is a new generation of wireless short-distance communication technology. It is newly designed from 0 to 1, driven by the need for personalized, diversified, innovative experiences in the Internet of everything era. Moreover, this technology is native to China and brings together the collective wisdom of more than 300 leading enterprises and institutions in China.

Among them, Huawei is the main contributor to the research and standard-setting of star flash technology.

At the last Huawei developer conference HDC, Huawei terminal CEO Yu Chengdong officially announced the combination of Hongmeng system 4.0 and Starflash technology, and brought a lot of application scenarios of Starflash technology, which was quite amazing.

So, what kind of new experience can Starflash technology bring to the human-computer interaction in the era of Wisdom? Let's talk about it today.

So you are such a star twinkle.

To understand the value of Starflash, we first need to know what kind of technology it is.

Bluetooth and Wi-Fi technology have always been the mainstream in short-range wireless communication, but after more than 20 years of development, they have been burdened with a heavy historical burden in order to be compatible forward, and are gradually unable to meet the needs of the new era.

"Star Flash" is actually a close-range wireless communication technology similar to Bluetooth and Wi-Fi. Although it is "similar", its birth is aimed at the shortcomings of Bluetooth and Wi-Fi, so it will be more advanced in architecture design and many technical details.

For example, the standards between Bluetooth and Wi-Fi are separated, Bluetooth focuses on low power consumption, Wi-Fi pursues high speed, each has its own advantages but is not compatible. The "Star Flash" from the architectural design to take this into account, into a standard multiple patterns.

As you can see from the system architecture diagram below, there are two modes in the access layer of Starflash: SLE and SLB. SLE to Bluetooth and SLB to Wi-Fi, but the basic services and applications above these two modes are integrated, which is equivalent to combining the advantages of Bluetooth and Wi-Fi.

Just like basketball players, players in the past were either tall but slow, or fast but short, but now there is a player who is tall and fast, so who doesn't like it?

Among them, SLE standard Bluetooth, and like Bluetooth are in the 2.4GHz unauthorized band, but it is more advanced in the specific technology, can achieve ultra-low delay and power consumption, and has stronger performance and longer coverage distance than Bluetooth.

For example, in the human-computer interaction scenario of keyboard and mouse, the delay of SLE can be as low as 250us, while Bluetooth can only achieve 7.5ms. Not only that, it can also bring the wireless mouse to the refresh rate of 4K, and the average Bluetooth mouse has only 125Hz.

This can be done because Starflash uses a lot of 5G-like technologies in empty port technology, while it is more advanced than Bluetooth and Wi-Fi in technical details.

For example, star flash is very similar to 5G in OFDM and CP design, time domain and frequency domain scheduling particles, and even uses 5G Polar coding technology, which brings the gain of sensitivity and the improvement of anti-jamming ability.

Seeing that Starflash technology is so advanced, I believe my friends also hope that it can mature and popularize as soon as possible. Speaking of which, we should not forget the promoter behind it, the Star Flash Alliance.

The Star Flash Alliance, established on September 22, 2020, is responsible for star flash technology research, standard setting, industrial landing and other activities, and currently has more than 320 members.

At the same time, Starflash Alliance has promoted the release of Starflash 1.0 standard, as well as complete Starflash testing and certification conditions. For example, at the International Starflash Wireless short distance Communications Alliance launch Summit held on July 1 this year, a number of Starflash Alliance innovation leading members officially released and displayed Starflash chips, modules, development boards, test instruments and quasi-commercial Demo, which indicates that Starflash's commercial landing has been driven into the fast lane. And this year is the first year of Star Flash business.

In the Star Flash Alliance, there is one member that has to be mentioned, that is Huawei. Huawei not only actively participates in Starflash's technology research and standard-setting activities, but also contributes its leading wireless communication experience and technology precipitation for more than 30 years, such as the 5G Polar coding technology just mentioned.

In the HDC of Huawei developer Conference, Huawei further promoted the landing and application of Xingluan Ecology through a series of actions.

Six values bring innovative experience, Hongmeng + Xingshen is a perfect match.

Just now we introduced the technological advantages brought by the innovative design of Star Flash technology in the physical layer, which will inject new value into the experience of many scenes such as human-computer interaction in the era of Wisdom.

At this HDC conference, Yu Chengdong, the CEO of Huawei, officially announced the cooperation between Hongmeng system and Starflash Technology, saying that Starflash technology will also bring six innovative experiences to Hongmeng Ecology, namely, lower energy consumption, faster data transmission, lower transmission delay, more stable and reliable wireless connection, wider signal coverage, and larger networking scale.

Specifically, for example, in terms of delay, star flash technology can reduce the communication and interaction delay between Hongmeng ecological terminals to the original 1max 30, increase the anti-interference ability of 7 dB, expand the coverage of signals between devices by two times as much as in the past, increase the maximum number of terminal connections by 10 times, and increase reliability from the original 90% to 99.99%. Every interaction can be hit accurately. These are considerable upgrades to the experience.

At the Hongmeng Zhaopin Summit on August 5, Huawei Hongmeng Zhaopin Ecology is also opening a cooperation with Xingshen, and held a Starflash cooperation launching ceremony. At the cooperation ceremony, Huawei announced that Xingshen will become the highest certification standard of Hongmeng Zhaopin S +.

I believe you can find that the soft bus and distributed characteristics of the Hongmeng system, the hardware ecology built by Hongmeng Zhaopin towards full scene intelligence, and the innovative advantages of Starflash technology can be said to be a natural match, and the combination of the two will inevitably lead to the upgrading of end-to-end experience. this upgrade will not only enhance the human-computer interaction experience of existing equipment, but also expect Hongmeng + Xingshen to collide with an innovative interactive experience. Achieve the effect of 1: 1 > 2.

Of course, as a new basic communication technology, Starflash can enable not only the interactive experience of Hongmeng Zhaopin, but also the change of human-computer interaction experience for all the devices that support it, but its combination with Hongmeng. People are particularly looking forward to it.

What is the ultimate human-computer interaction experience? That's it

Why is it so anticipated? If you have experienced the demonstration of Star Flash human-computer interaction Demo in this HDC, I believe you will understand.

In the demonstration, three kinds of wireless mice are compared: the ordinary Bluetooth mouse with 125Hz return, the 2.4G wireless mouse with 1KHz return and the Star Lightning Mouse with 4KHz return.

Using the 125Hz mouse to operate, I feel there is a delay, not very close to the hand, but because we used to use this kind of mouse most of the time, we are used to it. 1KHz's mouse operation experience is obviously better, but watching the animation of the mouse track on the computer, there is also a delay, especially when sliding quickly, the feeling of not following the hand is still obvious.

And then experience the e-sports mouse and computer connected wirelessly through Starflash, and it feels as if it has opened a new world. Under the blessing of the microsecond empty port transmission delay, the mouse easily achieves the 4KHz rate of return, with a high refresh rate display. When you use it, you can hardly see the delay when you look at the mouse trajectory animation on the computer screen. Even if it is a fast slide, it is also very easy to follow. This feeling is like painting on the screen with a marker, without muddling at all. If you look at the data of the real-time refresh rate of the mouse next to you, it is easy to get 3400Hz +.

In short, this is completely different from the wireless mouse we have experienced in the past. If we really experience it, the feeling will be more profound.

Delay and slow response are the most difficult to accept in the process of human-computer interaction. In the past, both Bluetooth and Wi-Fi are difficult to achieve low delay and ultra-sensitive response without induction, but these are the foundation and standard for star flashing.

This ultra-low latency and ultra-sensitive interaction is reflected not only in the use of wireless keymice on a single device, but also in more applications.

For example, multi-screen collaboration will be the most basic and high-frequency office scene in the future. Mobile phones, tablets and PC productivity devices cooperate with each other and can be input on different devices with only one set of keyboard and mouse. But in reality, when using Bluetooth or Wi-Fi to connect devices, the keyboard and mouse switch between different terminals is not always smooth, a setback, can be normal input, this interactive experience affects the efficiency and comfort of multi-screen office.

While the wireless keyboard and mouse supporting star flash technology and the terminal carry out multi-screen cooperation at the same time, they can quickly identify focus devices by virtue of the microsecond delay of star flash, so that when keys and mice switch between multiple devices, they can be truly seamless, as if the cooperative PC, tablet and mobile phone are a whole device, which can make your office productivity double smoothly.

In addition to low latency, Starflash also brings ultra-high concurrency to human-computer interaction in the Internet of everything era, supporting hundreds of terminals to connect at the same time, and networking up to 10 times the number of connections in Hongmeng Zhaopin ecology.

For example, in work meetings, conference rooms often do not have so many plug-ins, and you need to wirelessly connect keyboards, mice, headsets and even wireless large-screen displays and speakers at the same time to meet document processing and presentation. Voice communication, playing demonstration projects and other needs. In the past, almost every one of these wireless terminals needed a corresponding transceiver, and computers could not connect so many devices at the same time.

However, Starflash supports parallel connection of multiple devices and collision-free concurrency of multi-service uplink and uplink. The key point is that only one USB receiver is needed to realize the simultaneous access of these wireless accessories, which not only greatly reduces the complexity of multi-device pairing connection, but also avoids the problem that audio signals are easy to squeeze and stutter each other when Bluetooth multi-device access.

In the future, when people have meetings, they will no longer have to drag messy wires or many USB receivers. In addition to the conference office, we can also get help from Starflash technology when we connect to the wireless controller to play games. For example, many computers or mainframes are limited to a maximum of 2-4 handles, which cannot meet the demand when playing some multiplayer games. Under the blessing of strong high concurrency ability, Starflash technology can connect 8 handles at the same time, and it is no problem for the whole family to play together.

More useful is in some somatosensory games, we know that somatosensory games need to bind sensors on the body, the more sensors supported, the more accurate the motion capture, the less mistakes will be made in the game. Star flash technology can now support 10 somatosensory sensors to send and receive signals at the same time, and the signals can be aligned with microsecond errors, accurately capturing the movements of the user's head, torso and limbs, so that you can perform more elaborate dancing, fitness movements, and attack the enemy more accurately in the game.

Furthermore, with the blessing of Starflash technology, XR and meta-universe games can also be combined with more sensing accessories in the future, so that players can carry out all kinds of fine operations in the virtual world as in the real world, and the whole process is almost without delay, which will undoubtedly be an unprecedented and shocking game interaction experience.

The above features of high fineness, high concurrency and low latency will make you feel as if you are in a game. This is the ultimate immersive human-computer interaction experience.

When it comes to playing games, I believe you have also encountered a problem: for example, if you play games together at a company party, your seat is relatively far away, then the reliability of the handle operation will be greatly reduced, the keystroke will be ineffective, and the response speed will be interfered. Even control errors and so on, very affect the operation. All these are due to the poor coverage and low reliability of the Bluetooth connection, which is slightly farther away, although it can also be connected, but the signal quality has been greatly degraded, and it is easy to be interfered by other signals, resulting in transmission errors.

In the future, wireless handles, computers and mainframes that use star flash technology will no longer have this problem. As mentioned earlier, star flash equipment can rely on its own strong 5G Polar polarization code error correction ability, so that the transmission "foolproof", high reliability, no fear of errors. In fact, not only do we use wireless handles when playing games, but we can control them accurately over longer distances by using all other wireless controller devices.

In the era of Internet and mobile Internet, the main objects of human-computer interaction are PC and mobile phones, while in the era of the Alliance of everything, the objects of human-computer interaction will be greatly expanded. In addition to mobile computers, there will also be smart speakers, televisions, watches, headphones and various household appliances, and these devices are all connected wirelessly into a whole, which can be coordinated and controlled with each other, that is, the intelligence of the whole house.

At present, the intelligence of the whole house is mainly realized through Bluetooth and Wi-Fi connections, but I believe that friends who have experienced it will feel the same way. after there are many devices, the interference with each other is very serious, and they often disconnect and fail unwittingly. You want the intelligent speaker to lower the clothes rack, and it tells you that "the device has not been found". This is obviously not the smooth human-computer interaction of the whole house as we imagined.

In the future, with the blessing of Starflash technology, the whole house intelligence will be able to completely eliminate the potential conflicts between different connections through a unique interference and coordination mechanism, ensuring that many starflash devices do not stutter and connect continuously, so that when we interact with various terminals and household appliances in the intelligent scene of the whole house, we can really feel that they are "always online and responsive to a call."

Of course, not only the intelligent scene of the whole house, but also many application scenarios, our human-computer interaction experience can have stronger stability and anti-interference ability, such as working in a large office area with dense crowds. Your wireless keyboard and mouse will no longer be disconnected because there are too many Bluetooth devices in the environment, and when you wear starflash headphones to subway stations and airports, there will not be sound quality degradation and disconnection due to environmental interference.

Shi Yuanchun, a long professor in the Department of computer Science and Technology of Tsinghua University, once concluded that human-computer interaction is to make machines better adapt to human beings, human nature, manipulation, perception and cognitive ability.

Human nature likes simple, direct manipulation and cognition, repels even the slightest wait, and has the ability of multi-dimensional synchronous perception. The so-called ultimate human-computer interaction experience is also working in this direction.

As a connection technology and a transmission intermediary of human-computer interaction, Starflash makes us see the possibility of the ultimate human-computer interaction experience. It has a series of leading characteristics, such as low delay, high concurrency, anti-interference, high reliability and wide coverage, which accords with "human nature". At the same time, it is also trying to break down the barrier between people and machines, making the interaction more simple and direct, what they see, what they think, what they do, that is, what they get.

Conclusion

As we mentioned earlier, 2023 is the first year of Starflash's commercial use. Chips, modules and development boards are gradually maturing, and the testing and certification conditions are complete. In addition, during this HDC period, Hongmeng Zhaopin Ecology, which has 6400 + SKU, works closely with Starflash. It is believed that Starflash technology and ecological applications will develop rapidly in a foreseeable time.

In 2023, Star Flash Alliance was approved as an international industry and standards organization. Therefore, this technology is not only a milestone for China's communications industry, but also will open up a new world in the global short-range wireless communication market. We believe that in the future, Starflash will work together with Bluetooth and Wi-Fi to form a tripod situation and jointly create the ultimate wireless human-computer interaction experience for global users.
