The emergence and popularization of touch screens have gradually made us bid farewell to the years when we used physical keyboards to manipulate mobile phones. Today's trendy mobile phones cannot even find a physical keyboard on the main screen. The emergence of capacitive touch screens has even made mobile phones bid farewell to the standard stylus. We have begun to use one finger to click on two fingers to rotate and zoom to manipulate the screen. The influence of new materials on us is obvious. At this CES, several updated materials let us see the possibility of further changes in the way of interaction. The most exciting, naturally, is the flexible electronic screen when the computer screen can be bent or even folded, what does it mean? Yes, maybe one day we simply need to not worry about carrying a larger mobile phone screen, because then maybe the sleeves of our coat are made of flexible electronic screen, then only need to look at the arm and then a few light clicks to continue to interact with the smart terminal. At that time, the flexible electronic screen, which was integrated with clothes, may have also used the deformed touch technology that also appeared at CES this time. A bump will appear in all places that need to be clicked, which is convenient for you to click accurately, and you no longer have to worry about the tedium and inaccuracy of non-feedback interaction like the traditional touch screen. Of course, the further development of deformable touch technology can better control the hardness of the touch screen. When a screen can be hard or soft, the "Stephen Chow" scenario of a scarf a minute ago and a tablet computer a minute later may really appear in our lives. On that day, smartphones or tablets may be developed by digital giants and fashion giants. Materials are changing with each passing day, which is an important manifestation of the manufacturing industry entering the third industrial revolution, especially under the premise of the integration of information technology. For consumers, more new materials mean more new products. But for the industry giants, it means that every step of development will be a thrilling jump. Think of Nokia and BlackBerry. A few years ago, they were giants in the mobile phone industry, but they almost withdrew from the stage of history because they ignored the huge impact of touch screen on mobile phones. Of course, danger is organic. While the old giants are declining because they missed out on new material technology, there are bound to be new giants rising because of new material technology. The best case is 3D SystemsCorporation, which is famous for its 3D printing technology. The stock price of this technology company listed on the New York Stock Exchange has risen 266.33 percent in the past year. New materials are constantly changing the way we interact with electronic products, and this change will continue, even triggering a new revolution.
