The answer is this: When Sauers built a typewriter, he was surprised to find that a typist always broke down during normal typing. To solve this problem, Sauers went to his brother-in-law, a mathematician and school teacher, for help. His brother-in-law put forward a solution: separate the commonly used connected letters on the keyboard, so that the speed of keystroke will be slightly slower and the occurrence of faults will be reduced.
Shores happily adopted his brother-in-law's suggestion and arranged the letters in a strange QWERTY keyboard order. Sauers told the public that in order to avoid failure, the letters must be arranged out of order, which may be embarrassing. So he cleverly played a trick, saying that this arrangement is the most scientific and can speed up people's typing.
In fact, Sauers' statement has been recognized as "one of the biggest cheating activities in history" and "a complete lie" by the authorities in the history of British typewriter development.
Strangely, those more scientific keyboards designed by Sauers have been eliminated by history, but people are beginning to get used to using this strange arrangement of keyboards.
People have spent centuries trying to invent typewriters. In England, Henry Mill applied for a patent for a machine. The name of this machine is "man-made machine or tool for copying letters" With it, you can write a single letter or several letters in succession, just like writing. All written contents can be neatly and accurately copied on paper or parchment in capital letters, which is comparable to printing. That machine may not be sold because no one remembers its name.
The first typewriter used was Christopher latham's 1868. Shoals obtained the patent right. His machine is called a typewriter. He has a movable shelf, a joystick for changing typing paper and an alphabet keyboard.
But there's a problem with the shallows. In his original model, this arrangement of "ABC" keys often caused a key card when the typist typed quickly. Shoals doesn't know how to keep these keys from interfering with each other. His solution is to ask typists not to type too fast. Shoals asked his brother-in-law to rearrange the keyboard, so that the most commonly used letters would not be tested too close, and the type linkage could move in the opposite direction, so as not to collide and block the machine. The new arrangement is the QWERTY arrangement used by typists today. Of course, Shoals said that the new arrangement is scientific and can improve speed and efficiency. In fact, the only efficiency it improves is to slow down the typist, because almost no matter what word is typed in English, the typist's fingers are required to span a longer distance on the keyboard.
The advantages of typewriter certainly outweigh the disadvantages of this keyboard. Typists soon remembered this strange arrangement of letters, and the typewriter was a great success. By the time the typist remembers the new arrangement of letters, the typing speed has improved, the production technology of typewriters has also improved, and the letter keys are no longer blocked as easily as they were at first.
At present, the keyboard invented by Shoal is really not so good, and the arrangement of letters has too many shortcomings. For example, eight of the most commonly used letters 10 in English are too far away from the designated finger position, which is not conducive to improving typing speed; In addition, there are too many letters on the keyboard that need to be typed with the left hand, because most people are right-handed, and there are only 3,000 words in English that can be typed with the left hand, which is awkward to use. Some people have done statistics, using QWERTY keyboard, a skilled typist can move his fingers 25.7 kilometers in 8 hours, and he is exhausted at the end of the day. Unfortunately, thousands of people have become accustomed to it. Today, QWERTY keyboard still firmly occupies the input field of computer. Although some people have designed more scientific arrangement keys, they still can't become a climate. Modern computer keyboards don't have any cumbersome metal bars, which is of course unexpected for shoals.
