The modern development trend of the keyboard

If the CPU is the heart of the computer and the monitor is the face of the computer, then the keyboard is the mouth of the computer. It is the smooth communication between people and the computer. However, as the most peripheral products we have come into contact with, the role of the keyboard in most cases has been neglected. Of course, this is inextricably linked with the slow development.

"Big mouth" history of the PCXT/AT era of the keyboard mainly 83 key-based, and continued for a long period of time, but with the Windows system has been eliminated in recent years, such as Hewlett-Packard, Lenovo and other brand machines are the first The use of this type of keyboard has been widely praised and was once considered a feature of the brand machine. As time goes on, gradually, independent products with various quick functions appear on the market and are sold separately. They also have dedicated driver and setting software, and they can also be personalized on compatible machines.

A preliminary look at "mouth shape" shells Conventional keyboards have CapsLock (case lock), NumLock (numeric keypad lock), and ScrollLock 3 lights to mark the current state of the keyboard. These indicators are generally located in the upper right corner of the keyboard, but some keyboards such as Acer's ErgonomicKB and HP original keyboards use key caps built-in indicator light, it is easier to determine the current state of the keyboard, but due to the complexity of the process, most of the keyboard are not used design.

No matter how the form of the keyboard changes, the basic arrangement of buttons remains basically the same, and can be divided into a main keyboard area, a numeric auxiliary keyboard area, an F-key function keyboard area, a control key area, and a shortcut key area for the multifunctional keyboard.

The "three ports" contention keyboard can be divided into desktop computers, laptop keyboards, and IPC keyboards according to applications.

The traditional desktop keyboard is still the mainstream in the market, but no matter the appearance or technology, it has no essential difference compared with the products of a few years ago. With the improvement of the quality of life, the thick desktop keyboard is more and more incompatible with the stylish and healthy LCD display and the smart and comfortable optical mouse. The traditional desktop keyboard adopts a track-sliding type structure. Although the keystrokes of the keys are relatively long, the keys have a better feel, but due to the defects of the architecture itself, the sound when inputting the text is relatively large. Therefore, many well-known manufacturers have constantly reformed the traditional keyboard. For example, as a patriot of a well-known brand in the industry, he is skilled in technological innovation, good at grasping fashion, and has keen insights into demand. The ultra-thin feel KB-F920 launched in the second half of 2006 is even more refined. Its design concept continues the "ultra thin" concept, the thinnest keyboard less than 1cm, breaking the heavy stiff old keyboard. The arc of the lines is more natural and smooth, the buttons are slightly projected and full of texture, and the entire appearance is refined and elegant, allowing people to remember; at the same time, the Patriots are trying to help the user to easily face the flaws of the keyboard water, and carefully improve the product structure, strictly selecting Making materials, making waterproof design more perfect, making the development of traditional keyboard to a higher level.

Although the laptop keyboard did not appear in 2003, it was greatly glorified in 2003. The consistent feature of this type of keyboard is its compact size and stylish appearance. Many users choose the notebook keyboard to match the LCD monitor, so the entire desktop will look simple and stylish. In terms of keys, they use the structure of a laptop keyboard. The key will not cause the keycap to tilt because of uneven tapping force or incorrect position of the tap, and the phenomenon of the card key will not appear. At the same time, the intensity of the keystroke is relatively small, and the user cannot easily feel tired when inputting for a long time. In terms of silence, the notebook-based keyboard is designed to be quite good, and the user's input text is much smaller than the traditional desktop keyboard. In addition, the keyboard structure of the notebook-based keyboard is very short, and the conventional desktop keyboard is far from being touched when hitting.

"Word of mouth"

The development trend of the keyboard is more and more professional, and the performance of the keyboard varies according to the different purposes. For example, a game player basically has a display screen, or a lot of shortcut keys; and to frequently use the user, it is necessary to be equipped with easy-to-wash keyboard; there are able to shine keyboard, separate keyboard and so on. These are designed for the needs of users. For example, the keyboard designed for game applications - the ZBOARD gaming keyboard. The most outstanding feature of this keyboard is the built-in technical advantage. Compared with most other keyboards, which can simultaneously press two to four keys, the Battle Fighter keyboard can press up to seven keys at the same time. W/E/D 3 common keys can work at the same time, perfect solution to the problem of key position conflicts, so that the players in the game when the release of action instructions faster and more convenient.

The previous keyboard was only a simple operation on the computer, and now the keyboard gives more functionality. A multimedia-enabled keyboard allows users of the computer to control directly on the keyboard. There is no need to click on the small icon of the Internet on the screen with the mouse. In the same way, there are also specific keys that can control the CD-ROM, Internet keys, send and receive E-mail keys, sound adjustment keys readily available. Some have a circular adjustment disk under the keyboard. This adjustment disk can be used instead of the mouse function.

The hottest wireless technology on the market is also applied to the keyboard. The application of wireless technology allows you to get rid of the restrictions and constraints of the keyboard line, one end is a computer, the other end you can be free, free to operate, mainly Bluetooth, infrared and so on. The two have different distances and anti-jamming performance. In general, Bluetooth is superior to infrared in terms of transmission distance and security. The effective transmission distance of infrared rays is about 1 to 2 meters, and the effective distance of Bluetooth is about 10 meters. It can be seen from this that the future of wireless keyboards is infinite. It is not only to solve the problem of computer peripheral equipment, but also paves the way for the future development of computer-based entertainment. Use the TV screen to browse the Internet and watch online TV programs. Can use the wireless keyboard to control, wireless features have been fully demonstrated.
