RSI Prevention: All About Computer Keyboards


When choosing a keyboard for your computer, do not just think about its look, function, and whether it will match your computer system or not. More importantly, consider your health by making sure that your keyboard will not cause your repetitive stress injury such as carpal tunnel syndrome when you use it often and for long periods of time.


A computer keyboard is a computer peripheral used as a data input device for keying in characters and commands to control the operation of the computer. It consists of letters, numbers, and symbols partially arranged and modeled after the typewriter keyboard. It also has additional functions for computer-specific commands. The keys are pressed simultaneously to perform these commands.


Types of Computer Keyboards


First, there is the basic computer keyboard. In principle, the basic keyboard design is governed by the ISO/IEC 9995 international standard. It is a flat rectangular pad with a keyboard cable that connects to the back of the computer hardware or CPU. It corresponds to the operating system and software.


Your second option would be an illuminated keyboard. This is a computer keyboard that uses a special backlight that allows the keys to be easily seen when working in poorly lit areas. It is ideally used at night.


Then, there is the ergonomic keyboard, a special keyboard that follows the natural contours of the fingers, palms, and hands. It provides the most relaxing and harmless way of typing on a keyboard. It is ideal for those who type or access the computer the whole day, since it is made with a palm and thumb rest. Its keys are arranged to provide the utmost comfort.


There is also what is known as the industrial keyboard. An industrial keyboard follows the standard specification designs for a rackmount cabinet. It has system security and space conservation features. It is made from heavy-duty and high-grade materials to withstand industrial operations.


If you are left-handed, you may want to get a left-handed computer keyboard that is especially designed for the lefties. It’s left and right sides are switched to make it easier to use.


Finally, there is the wireless keyboard. A wireless keyboard does not need a cable to connect to the computer. Instead, it uses infrared or Bluetooth technology. It is powered by batteries. However, it poses an “eavesdropping” security risk.


Choosing a Computer Keyboard


Aside from its function, design, and ease of use, keyboards should make your working life easier and prevent you from building stress and tension on your hands and wrist. Thus, the perfect keyboard to choose is the one that provides comfort and ergonomics for your fingers and hand. A wireless keyboard can also be a good choice since you will not be limited by a cord and you can move it closer to your body for ease and comfort, too.



More importantly, no matter how perfect and ergonomically-created your keyboard is, you should still not let typing and computer work get the best of you. Take a break once in a while to prevent stress and injuries on your hands.
