Qwerty & Dvorak Keyboards!


Qwerty keyboard layout was designed by Christopher Sholes in 1868 and was patented by himself in 1874. In the begining all keys were arranged alphabetically.

Later he noticed that when typists type at a faster rate the key would stick or jam. It is believed that he placed all frequently used keys as far apart from each other to resolve this problem.Thus the QWERTY design was formed to solve the slow mechanical movement of earlier typewriters. It was not designed for today’s use, because touch typing had not been developed at that time.

The layout of the keyboard letters on the home row is arranged as QWERTY. Hence the name QWERTY.

DVORAK keyboard was patented in 1936 by Dr. August Dvorak, who worked as a professor and educational psychologist in the University of Washington.

The Dvorak keyboard layout has got all the vowels and consonants in the home row. These are the letters a typist uses most frequently. Thus, the DVORAK keyboard layout reduces the distance travelled by the fingers.

The vowels and consonants are arranged in such a way that a fast and accurate typing rythm can be achieved.The keying is right-hand, left-hand, right-hand and then left-hand. It is called back and forth flow, which makes typing much faster. 

In a QWERTY keyboard the typist’s fingers has to cover a lot more distance than on a Dvorak keyboard.

Moreover, the possibility of having carpal tunnel syndrome and other repetitive motion injuries are less when we use DVORAK.

Even if it is very good to use DVORAK did not become popular. One of the reasons for this was: by the time Dvorak was designed there were hundreds of thousands of QWERTY typewriters available and it would have cost a lot to convert them all to DVORAK. Additionally, the typists were already familiar with the QWERTY typewriters.
