Hope to adopt it~!
As we all know, computer keyboard letters are arranged in a chaotic order. Maybe you are wondering: Why are the letters arranged in the same order on all computers, printers and typesetting equipment? Why is the distribution of letters not in English alphabetical order but chaotic and irregular? The answer is this: Sauer After Si built the typewriter, he strangely discovered that a typist always failed when typing normally. To solve this problem, Sauers asked his brother-in-law, a mathematician and schoolteacher, for help. His brother-in-law came up with a solution: separate the commonly used letters on the keyboard, which would slow down the keystrokes slightly and reduce the risk of malfunctions. Sauers readily adopted his brother-in-law's suggestion to arrange the letters in a strange QWERTY order. Sauers might have been embarrassed to tell the public that the letters had to be arranged haphazardly to avoid malfunctions. So, he cleverly played a trick, saying that this arrangement was the most scientific and could speed up people's typing speed. In fact, Sauers's statement has been regarded as "one of the largest deceptions in history" and a "complete lie" by authorities on the history of the development of British typewriters. Strangely, those more scientific keyboards that were different from Sauers' designs were eliminated by history, while people gradually became accustomed to using this weirdly arranged keyboard.
People spent centuries trying to invent the typewriter. In 1714 in England, Henry Mill applied for a patent for a machine called "an artificial machine or instrument for copying letters, by which a single letter can be written, as in writing, or several letters in succession. All writing could be transcribed neatly and accurately on paper or parchment in capital letters, as if printed.” That machine probably won't be bought because no one can remember its name. The first typewriter used was in the United States in 1868 by Christopher Latham. Shores patented. His machine was called a typewriter. It had movable stands, levers that redirected typewriter paper, and alphabetical keyboards. But Shores had a problem. On his original model, its "ABC" key arrangement often caused the keys to jam when typists typed quickly. Shores didn't know how to keep the keys from interfering with each other. His solution was to stop the typist from typing too fast. Shores asked his brother-in-law to rearrange the keyboard so that the most commonly used letters would not be too close together and so that the type linkage rods could move in opposite directions so that they would not collide and jam the machine. The new arrangement was the QWERTY arrangement used by typists today. Of course, Shores said the new arrangement was scientific and would increase speed and efficiency. In fact, the only efficiency it adds is to slow down the typist, because typing almost any word in English requires the typist's fingers to cover a longer distance on the keyboard. The advantages of a typewriter certainly outweigh the disadvantages of this keyboard. Typists quickly memorized the strange letter arrangement, and the typewriter became an instant success. By the time typists had memorized the new arrangement of letters and typed faster, typewriter technology had improved and the letter keys no longer jammed as easily as they had originally. From today's perspective, the keyboard invented by Shores is really not very good, and its letter arrangement has too many shortcomings. For example, 8 of the 10 most commonly used letters in English are too far away from the prescribed 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" "Zi", there are only about 3,000 words in English that can be typed with the left hand, so it is very awkward to use it. Someone once made statistics that using a QWERTY keyboard, a skilled typist's fingers move up to 25.7 kilometers in 8 hours, making him exhausted at the end of the day. Unfortunately, the habits of hundreds of people have become natural, and the QWERTY keyboard still firmly occupies the computer input field today. Although some people have designed a more scientific key arrangement long ago, it has never become a trend.
Modern computer keyboards do not have cumbersome metal rods at all, which is of course something Sholes did not expect
