Why is the letter arrangement of computer keyboard qwert'' instead of ABCD'''?
At present, the keyboard commonly used by the public is called "fast hoof keyboard", and the original text is "QWERTY". Has anyone found that this word looks a little familiar and unfamiliar, but it is actually a combination of the first row of letters on the keyboard? Please look at the following three lines of letters:
Q
W
E
rare
T
Y
U
I
O
P
A
S
D
F
G
H
J
K
L
Z
X
C
V
B
ordinary
M
The first typewriter appeared in 1868.
This is the arrangement order of all computer keyboard letters or English typewriter keyboard letters. Interested readers may wonder: Why do you want to arrange 26 letters in this random way? It is difficult to remember and master. The original keyboards were basically arranged alphabetically, but in order to prevent the typewriter from hitting too fast, the mechanical rods supporting the keyboards collided with each other and caused failures, so the positions of some letters were adjusted, forming what it is today. It is said that the reason is this:
19 in the 1970s, Shoals company (Sholes
Company) was the largest typewriter manufacturer at that time. Because the mechanical technology at that time was not perfect, the keys rebounded slowly after hitting. 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. To this end, the company often receives complaints from customers.
In order to solve this problem, designers and engineers have been racking their brains, because there is really no way to increase the rebound speed of keys. Later, a clever engineer suggested that on the one hand, the keys of the typewriter were twisted too slowly, on the other hand, the typist was typing too fast. Since we can't increase the speed at which the keys pop up, why not try to slow down the typist's keystrokes? This is undoubtedly a new idea. There are many ways to slow down the typist's keystrokes. The easiest way is to disrupt the arrangement of 26 letters and put the more commonly used letters under clumsy fingers. For example, the letter "O" is the third most frequently used letter in English, but it is placed under the ring finger of the right hand. The letters "S" and "A" are also commonly used letters, which are used for the clumsy left hand ring finger and little finger. For the same reason, uncommon letters such as "V", "J" and "U" are handled by the most flexible index finger.
Thus, this "QWERTY" combination keyboard was born and gradually formed. Later, due to the development of materials and technology, the key bounces much faster than the typist, but the alphabetical order of the keyboard cannot be changed.
This arrangement does bring a lot of trouble to beginners in input. In fact, as early as 1936, someone noticed this problem and introduced a more ergonomic keyboard. Unfortunately, this keyboard died before it went on sale in World War II. Recently, a group actively promoted this keyboard named "Devzak", and perhaps in the near future, the new alphabet arrangement will be widely adopted.
