A few days ago, the keyboard widely used by the public was called "fast hoof keyboard", and the original text was "QWERTY". Do these irregular letters look familiar? Yes, it is a combination of the letters on the left of the first line on the keyboard. The English arrangement order on the "fast hoof keyboard" is exactly the arrangement order of English typewriter keyboard letters. This paper will deeply discuss the origin and characteristics of QWERTY keyboard, so as to help readers better understand the history and development of keyboard.

Mechanical technology is not perfect.

The letters of early typewriters were not arranged in this way, but the mechanical technology at that time was not perfect, which made the keys bounce back slowly after being hit. Once the typist hits the keys too fast, the two keys are easily twisted together and have to be carefully separated by hand, which seriously affects the typing speed.

The easiest way to slow down typing.

In order to solve the problem that typists are typing too fast, Christopher latham Shoals, an American, decided to use the simplest method to reduce the typing speed, that is, to transform the keyboard.

Disrupt the arrangement of 26 letters

His idea is to disrupt the arrangement of 26 letters and put the more commonly used letters under clumsy fingers. For example, the letters "Q", "S" and "A" are frequently used, but they are hit by the clumsiest right hand ring finger, left hand ring finger and left hand little finger. Unusual letters such as "V", "J" and "U" are handled with the most flexible index finger.

Very inefficient

"QWERTY" keyboard is very inefficient. According to statistics, after typing for a few hours, the average finger movement distance is more than 20 kilometers, so there have been many reasonable alphabetical design schemes, but none of them can be popularized, which shows that the power of habit is very strong.
