Huawei Notebook 1 12 15 What is the technology of ultrasonic control? Huawei officially released the product preheating information, and it is very likely that Huawei will release a new heavy notebook this month. Before the official preheating poster, it was reported that "Huawei notebooks will support ultrasonic control", and many friends may put a question mark when they see ultrasonic control. How is this technology used in notebook computers and what is its use?
What kind of immortal technology is ultrasonic manipulation?
Ultrasound sounds cool literally, but in fact, it is really not a technology that we can easily use in our daily life. Precision measurement is an application scene of ultrasound, but it is very professional. For example, ultrasonic wave detector can be used to measure the flow, channel and depth of reservoirs, lakes, rivers, shallow seas and other water bodies.
When sounding, the ultrasonic instrument is placed on the water surface or at a certain depth, and the detailed data are calculated by using the fixed sound speed of ultrasonic waves in water and the time from ultrasonic transmission to reception.
Can I use the new Huawei laptop to work in the field of professional data? For example, if it is used in mining, sports competitions, professional training, logistics and transportation, it is likely to be equipped with some extended sensor peripherals, such as positioning devices and scanning devices.
Another application direction of ultrasonic application: ultrasonic propulsion. A company named NTT· Dokomo has introduced a new unmanned aerial vehicle, which uses a round helium-filled balloon and an ultrasonic propulsion system. No propeller is needed, and the balloon filled with helium can remain suspended in the sky with minimum energy consumption. Compared with traditional drones, it is super quiet, without the hum of propellers and motors, and can collect more data, including photos and videos.
Reliable speculation about Huawei's new PC
Huawei's analysis of scene applications has been superb, never simply pursuing the dazzling skills of technology, but striving to solve the actual pain points in users' use. However, considering Huawei's pragmatic style, it is unlikely that the notebook will float, but it is not impossible to use the computer smoothly through remote operation.
What is the ultrasonic control technology of Huawei notebook? In today's AI artificial intelligence era, the fusion of algorithms and hardware endows the machine itself with more "self-awareness" similar to human beings. For example, it can accurately identify and predict the user's operation intention, and thus automatically respond. The most typical example is "remote control".
Previously, on Huawei smartphones, users simply pointed their palms at the front of the front camera and waved their wrists in the air, so the screen could slide up and down or take screenshots in the air. This kind of futuristic human-computer interaction is very practical in reality, which can solve the control pain point that users can't touch the screen with their hands in cooking, eating, lying down and other scenes.
Now, it is said that Huawei's more powerful "air control" is coming. On 12 and 15, it was reported that Huawei's new PC products will support ultrasonic control, and the official new product preheating information seems to confirm this. Literally, the biggest difference from the past is that Huawei has adopted a brand-new ultrasonic technology. What are the advantages of the new "black technology" and what functional changes can it bring to users?
What is the so-called ultrasonic technology?
The frequency range of the sound that the human ear can hear is between 200,000 and 20,000 hertz (Hz). The fluctuation above this range is called ultrasonic wave, and the sound below this range is called infrasound wave.
Ultrasound is widely used in real life, such as color Doppler ultrasound and B-ultrasound in medical field, ultrasonic glasses cleaning box starting from 100 yuan in consumer field, and ultrasonic screen fingerprint recognition in smart phones. In addition, there are more professional industrial automation control, pharmacy, circuit detection and so on.
In fact, some manufacturers have previously introduced the use of "ultrasonic technology" to achieve long-distance gesture operation. At the MWC exhibition of 20 19, the Elliptic Laboratory demonstrated the "ultrasonic gesture recognition technology". They integrate ultrasonic sensors into the equipment and then emit ultrasonic waves through speakers. At this time, the sound waves hitting the user's palm will rebound, and finally the device microphone will collect sound waves and induce the user's gestures.
Based on this, we can boldly guess that Huawei's new products will support ultrasonic control, which is also a similar technical principle. However, this "ultrasonic control" technology belongs to Huawei's brand-new patent, and it must be different.
Looking forward to the practical application, what functional experience can Huawei ultrasonic control bring?
First of all, ultrasonic operation significantly improves the working efficiency of independent foundation. For example, with the help of ultrasonic technology, the recognition speed and accuracy will definitely be greatly improved. At least, we don't need to carefully point our palms at the front camera, and we can do it with a wave of our hands.
Second, bring more advanced and smarter advanced gameplay. Through the "ultrasonic technology", the machine can calculate the sound speed and frequency of the user's hand moving in front of the screen, and detect the three-dimensional position of the gesture, which provides us with unlimited imagination space. In the future, we may be able to complete special functions such as handwriting input, painting, biometrics and playing games from a distance.
Third, eliminate nuclear weapons and realize "remote global control". Combining the technical characteristics of the first item and the second item, it is obvious that with the blessing of "ultrasonic control", we can almost meet most of the operating requirements, then the mouse may become useless in the future, just use your hands directly, and the beautiful blueprint of "long-distance global control" is not far away.
Undoubtedly, the "wonderful use" of ultrasonic technology is very rich, but it has been widely used in the field of high-tech production before, and the perception of functional attributes brought by mass consumption is not strong. This time, through technological innovation, Huawei applied and popularized "ultrasonic control" to civilian-grade PC products for the first time, which not only brought efficient and practical "black technology" functions to users, but more importantly opened the door to a new "human-computer interaction mode" in the future, which is of great significance.
The landing product that can take the lead in carrying Huawei's "ultrasonic control" technology must have performed well in other aspects, and it can indeed be called "Huawei's strongest flagship PC of the year", which is very worthy of your expectation and attention.
What is the ultrasonic control technology of Huawei notebook? 3 Huawei officially released new product information, saying that Huawei notebooks will support ultrasonic control, which immediately triggered a wide discussion of Huawei fever powder. Some netizens think that this technology is very futuristic, or it may subvert the PC industry, which makes people more and more curious about ultrasonic technology.
However, in order to understand the ultrasonic operation, we must first briefly understand the ultrasonic itself and some known applications.
We call the sound wave with frequency higher than 20KHz ultrasonic wave, which has extremely short wavelength and good directivity and penetration ability. It can be used for speed measurement, distance measurement, disinfection and sterilization, cleaning, welding and so on.
At present, ultrasonic technology has applications in many aspects of life, such as medicine, ultrasonic cleaning, ultrasonic ranging and so on. For example, in clinical treatment, we use "high-power ultrasound" to kill tumor cells, ultrasonic acupuncture. We know that the energy of ultrasound is very high. Using medical imaging technology, multiple ultrasonic beams are focused on diseased cells, and the intensity and time of irradiation are controlled to make the temperature reach 70~ 100℃ in a short time, killing diseased cells and protecting surrounding tissues. Ultrasonic acupuncture uses ultrasonic technology to stimulate acupoints. This therapy has the advantages of no damage to tissues, no pain and no adaptability. In addition, ultrasound is often used in extracorporeal lithotripsy, physical therapy, dentistry and so on.
In addition to "power ultrasound", there are also related applications of "detection ultrasound", that is, using the directional characteristics of high-frequency acoustic radiation of ultrasound itself, the distance of objects, the composition and density of substances can be detected by analyzing the information reflected by sound waves. Common applications include sonar, biomedical ultrasonic imaging, ultrasonic nondestructive testing, acoustic logging and so on. From this point of view, after the remote control equipment empowers the PC industry, it should bring consumers a new way of interaction.
Perhaps in the near future, when users use the new Huawei smart office laptop to display PPT and photos in the conference room, they can use their hands instead of the remote control to give off-screen instructions, and they can flip the pages of PPT and photos up and down just by waving their arms. In leisure and entertainment, they can easily control video playback, switch screen content, control volume and so on. In the near future, simple drawing and even games on equipment may be controlled by ultrasound.
From this point of view, Huawei's new PC product pioneered the "ultrasonic remote control" black technology, and the further innovation on the basis of the original interactive experience may be to further bring "mouse-free" interaction to users.
As a production tool, computer is also the projection of our state, emotion and cognition in our work and life. Only by continuous innovation can we bring value to users. At this new Huawei smart office product launch conference, I believe this new "black technology" product supporting long-distance ultrasonic operation will bring us many surprises. Let us wait and see, and look forward to the debut of Huawei's strongest flagship of the year!
