Q. Describe Ergonomic Keyboards?
Ergonomics is the study of environment, conditions as well as efficiency of workers. Ergonomics proposes that keyboard wasn't designed with human beings in mind. Certainly continuous typing can be dangerous to health. This can lead to pain or some ailments like the Carpal Tunnel Syndrome.
For normal typing on a keyboard you have to place your hands separately bending them at wrists and hold this position for a long time. You also have to bend your wrist vertically in particular if you elevate your keyboard employing the little feet behind keyboards. This stresses the wrist ligaments and squeezes the nerves running in the hand by the Carpal tunnel through wrist bones.
To decrease the stress keyboards known as ergonomic keyboards have been designed. These split the keyboard in two and angle the two halves so as to keep wrists straight. To decrease vertical stress many keyboards also offer extended wrist rests. For those who indulge in heavy, regular typing it's recommended that they employ more ergonomics based keyboards and follow ergonomic advice in all aspects of their workplace.
