Who invented the keyboard?

Keyboards have a long history. As early as 17 14, people in Britain, America, France, Italy, Switzerland and other countries began to invent various types of typewriters. The earliest keyboards were used on typewriters with immature technology at that time. Until 1868, Christopher Latham Sholes, the American "father of typewriter", obtained the patent of typewriter model and the right to operate it. A few years later, he designed a practical form of modern typewriter and standardized the keyboard for the first time, which is now the "QWERTY" keyboard. Why should the keyboard be standardized to the current "QWERTY" keyboard key layout? This is because at first, the keyboards of typewriters were arranged in alphabetical order, and typewriters were all-mechanical typing tools. Therefore, if the typing speed is too fast, some key combinations are easy to get stuck, so Christopher Latham Sholes invented the QWERTY keyboard layout. He put the most commonly used letters in the opposite direction, slowed down the typing speed to the maximum extent and avoided the key jam. Shoals applied for a patent in 1868, and the first commercial typewriter with this layout was successfully put on the market in 1873. This is why there is today's keyboard arrangement. QWERTY's keyboard key layout is very inefficient. For example, most typists are right-handed, but with the QWERTY keyboard, the left hand takes up 57% of the work. The two little fingers and the ring finger of the left hand are the weakest fingers, but they are used frequently. The utilization rate of letters in the middle column only accounts for about 30% of the whole typing workload, so in order to type a word, you often have to move your fingers up and down. 1888 held an open typing competition in the United States. Ma Jialin, a court stenographer, showed his blind typing skills according to the clear division of fingering, and the mistakes were only three ten thousandths, which surprised the people present. According to the records, Ma Jialin's prize was 500 yuan. Since then, many people have followed this blind typing, and the United States has also begun to set up schools to train typists. Because of the appearance of blind typing technology, the keystroke speed is enough to meet the needs of daily work. However, 60 years later (1934), a man named dvorak invented a new arrangement method, which enabled his left and right hands to alternately type more words. This keyboard can shorten the training period by 1/2 times and increase the average speed by 35%. Dvorak's keyboard layout principle is: 1, try to strike alternately with your left and right hands to avoid one-handed combo; 2. The average moving distance of verbal attack keys is the smallest; 3. The most commonly used letters should be ranked in the key position. More reasonable and efficient than DUORAK keyboard is the malt keyboard invented by Lillian Malt. It changes the original staggered rows of character keys, makes the thumb easier to use, and makes the keys such as backspace, which were far away from the center of the keyboard, easier to reach. But the malt keyboard needs special hardware to be installed on the computer, so it has not been widely used. By the middle of the 20th century, the keyboard had another use-as a basic input device for computers. On the other hand, up to now, "QWERTY" keyboard is still the most used keyboard layout, which is a very typical example of "inferior products win superior products". No matter who invented it, just look at this information: the origin of computer keyboard /A/7893/2294.html Concise information: the history of keyboard/A/7893/2304. As we all know, the letters of computer keyboard are arranged in an unordered order. Maybe you will wonder: Why are the letters arranged in the same order on all computers, printers and typesetting equipment? Why is the distribution of letters not arranged in alphabetical order, and there is no rule to follow? 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. The reason for the arrangement of letters on the keyboard 1860 invented the typewriter, but the purpose of breaking up the letters into discontinuities was to. In the 1980s, when typewriters were just budding in the United States, many people would unconsciously type faster and faster, resulting in mechanical failures (such as tangled typing and jammed keys). In order to reduce the time wasted by users in repairing the mechanical faults of typewriters, the engineer Christopher Sholes skillfully designed the usual QWERTY keyboard letter arrangement shown on the right, breaking the letters into discontinuous parts to reduce the typing speed of typists. When you understand this, you will find it hard to imagine. If you want to see it further, you can go online: /awe/pages/features/qwerty. Shtml Today, the mechanical problems of computer keyboards have disappeared, but we still have to continue to learn 26 English letters with irregular positions according to the old design of19th century.
