Huawei officially released new product information that Huawei notebooks or will support ultrasonic control, which immediately triggered extensive discussion of Huawei's fever powder. Some netizens believe that this technology is very futuristic, or may subvert the PC industry, which also makes people more and more curious about ultrasonic technology.
However, to understand ultrasonic manipulation, we must first briefly understand the ultrasonic itself and some of the currently known applications.
We call sound waves with frequencies higher than 20KHz ultrasonic waves, which have extremely short wavelengths and good directionality and penetration. It can be used to measure speed, distance, disinfection and sterilization, cleaning, welding, etc.
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 and ultrasonic acupuncture, we know that the power of ultrasound is very large, the use of medical imaging technology, the multi-beam ultrasound is focused on the diseased cells, control the intensity and time of irradiation, the temperature of a short time will reach 70 ~ 100 ° C, while protecting the surrounding tissues while killing the diseased cells. Ultrasound acupuncture is the use of ultrasonic technology to stimulate acupuncture points, this therapy has no damage to tissues, and has the advantages of painlessness and adaptation. In addition, ultrasound is often used in external lithotripsy, physiotherapy, dentistry, etc.
In addition to "power ultrasound", there is also a related application of "detection ultrasound", that is, the use of the directional characteristics of high-frequency acoustic radiation of ultrasonic waves themselves, through the analysis of the information reflected by sound waves, to detect the distance of the object, the composition of the substance, and the density. Common applications include sonar, biomedical ultrasound imaging, unisondesonic testing, acoustic logging, etc. From this point of view, after the air control device empowers the PC industry, it should bring a new way of interaction to consumers.
Perhaps in the near future, when users use the new Huawei smart office laptop to screen PPT and photos in the conference room, they can replace the remote control with their hands, give instructions to the screen, just wave their arms, you can turn the page up and down on the PPT and photos, and when leisure and entertainment, you can easily control video playback, switch screen content, control volume, etc. In the near future, simple drawing, and even games on the device may be able to use ultrasonic control.
In this way, Huawei's new PC product pioneered the "ultrasonic air control" black technology, further innovating on the basis of the original interactive experience, perhaps to further bring users a "mouseless" interaction method.
As a production tool, the computer is also a projection of our state, emotions, and cognition when we work and live. Only continuous innovation can bring value to users. At this Huawei smart office new product conference, I believe that this new "black technology" product that supports ultrasonic air operation may bring many highlights that surprise us, let us wait and see, and look forward to the appearance of Huawei's strongest flagship of the year!
