After Sauers built the typewriter, he strangely found that a typist always failed when typing normally. In order to solve this problem, Sauers went to ask him My brother-in-law, a mathematician and schoolteacher, came up with a solution: Split the commonly used letters on the keyboard so that the keystrokes would be slightly slower and less likely to occur. The malfunction occurred. \x0d Sauers happily adopted his brother-in-law's suggestion to arrange the letters in a strange QWERTY order. In order to avoid the malfunction, the letters had to be arranged haphazardly, and telling the public about this fact might This would make Sauers feel embarrassed. So he cleverly played a trick, saying that this arrangement was the most scientific and could speed up people's typing speed.\x0dIn fact, Sauers's statement has been adopted by British typewriters Authoritative sources in the history of development identified it as "one of the largest deceptions in history" and a "complete lie".\x0dWhat is strange is that those more scientific keyboards that were different from Sauers' designs were eliminated by history. , and people gradually became accustomed to using this weirdly arranged keyboard. \x0dIt took people centuries to try to invent the typewriter. In 1714 in England, Henry Mill applied for a patent for a machine that gave its name A man-made machine or tool called "copying letters", which can be used to write a single letter alone or several letters in a row just like writing. All written content can be copied neatly and accurately on paper or parchment in capital letters. "As good as printing". That machine probably couldn't be bought because no one could remember its name.\x0dThe first typewriter in use was in the United States in 1868 by Christopher Latham Shore. Sholes patented it. His machine was called a typewriter. It had a movable frame, a lever that moved the typed paper, and an alphabetical keyboard.\x0dBut Sholes had a problem. In his On the 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 let the typists Clerks should not type 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 to allow the type linkage rods to move in opposite directions so they would not collide. They jammed the machine together. The new arrangement was the QWERTY arrangement used by typists today. Of course, Shores claimed that the new arrangement was scientific and could improve speed and efficiency. In fact, the only efficiency it improved was that it made typists slower. down, because typing almost any word in English requires the typist's fingers to cover a longer distance on the keyboard.\x0dThe advantages of the typewriter certainly outweigh the disadvantages of this keyboard. Typists quickly memorized the strange letter arrangement, The typewriter was an immediate success. By the time typists had memorized the new arrangement of letters and their typing speeds had increased, typewriter manufacturing technology had also improved, and the letter keys no longer clogged as easily as they had originally.\x0dToday From a personal perspective, the keyboard invented by Shores is really not that good. 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 positions, 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 about 3,000 words in English that can be typed with the left hand, so
It is very awkward to use. Some people have made statistics. Using 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, thousands of people have become accustomed to QWERTY. The keyboard still firmly occupies the computer input field today. Although some people have long designed a more scientific key arrangement, it has never become a trend. Modern computer keyboards do not have cumbersome metal rods and the like at all. This is of course the result of Sholes. Something we didn't expect.\x0dThe keyboard currently commonly used by the public is called "QWERTY", the original text is "QWERTY". Has anyone noticed that this word looks a little familiar and a little strange, but in fact it is the first row of the keyboard. The combination of letters. Please look at the following three rows of letters:\x0dQ W E R T Y U I O P\x0dA S D F G H J K L\x0dZ You will feel strange: Why should 26 letters be arranged in such an irregular manner? It is difficult to remember and master. The original keyboard was basically arranged in alphabetical order, but in order to prevent the typist from typing too fast, the keyboard was not supported The mechanical rods collided with each other and caused a malfunction, so the position of some letters was adjusted to form what it looks like today. It is said that the reason is this:\x0dIn the 1870s, Sholes Co. was the largest specialized company at the time. Manufacturer of typewriters. Due to the imperfect mechanical technology at that time, the keys bounce back slowly after being hit. Once the typist hits the keys too fast, it is easy for the two keys to get twisted together. You must use The hands are very careful to separate them, which seriously affects the typing speed. For this reason, the company often receives complaints from customers.\x0dIn order to solve this problem, designers and engineers have been racking their brains because there is really no way to add more character keys. Later, a smart engineer suggested that the reason why the typewriter keys are twisted is, of course, that the rebound speed of the keys is slow, and the typist's keystroke speed is too fast. Since we can't improve Why not try to reduce the typist's typing speed when it comes to the speed at which the keys bounce? This is undoubtedly a new idea. There are many ways to reduce the typist's typing speed. The simplest method is to disrupt the arrangement of the 26 letters. order, placing 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" is also a very frequently used letter, but it is given to the clumsiest ring finger and little finger of the left hand to hit. For the same reason, letters such as "V", "J" and "U" that are used less frequently are struck by The most flexible index finger is responsible.\x0d As a result, this "QWERTY" combination keyboard was born and gradually became finalized. Later, due to the development of materials and technology, the rebound speed of the keys was much greater than the typist's strokes. Key speed, but the keyboard alphabetical order cannot be changed.\x0dThis arrangement does cause a lot of input troubles for beginners. In fact, someone noticed this problem as early as 1936 and introduced a more ergonomic keyboard. , it is a pity that during the Second World War, this keyboard died before it was launched. Recently, a group has been actively promoting this keyboard called "Dvorzak". Maybe in the near future, the new letter arrangement method will be widely used. Adoption.
Keyboards have a very long history. As early as 1714, people from Britain, the United States, France, Italy, Switzerland and other countries began to invent various types of typewriters. The earliest keyboards were used at that time. On typewriters whose technology was not yet mature. It was not until 1868 that the American Christopher Latham Sholes, the "father of the typewriter", obtained a patent for the typewriter model and obtained the operating rights. A few years later, he designed a practical version of the modern typewriter. Form and standardized the keyboard for the first time, now known as the "QWERTY" keyboard.
?
Why should the keyboard be standardized into the current "QWERTY" keyboard key layout? This is because originally, the keyboard of the typewriter was arranged in alphabetical order, and the typewriter was a fully mechanical typing tool. Therefore, if the typing speed was too fast, certain key combinations were prone to jamming problems, so Christopher Christopher Latham Sholes invented the QWERTY keyboard layout. He placed the most commonly used letters in opposite directions to slow down typing as much as possible to avoid key jams. Shores applied for a patent in 1868, and the first commercial typewriter using this layout was successfully put on the market in 1873. That's why keyboards are arranged the way they are today. ?
QWERTY keyboard key layout is very inefficient. For example: Most typists are right-handed, but when using a QWERTY keyboard, the left hand does 57% of the work. The two little fingers and the left ring finger are the weakest fingers, but they are used frequently. The usage rate of the letters in the middle column only accounts for about 30% of the entire typing work. Therefore, in order to type a word, you often have to move your fingers up and down. ?
In 1888, a public typing competition was held across the United States. Magalin, a court stenographer, demonstrated his touch typing skills according to a clear division of fingering. The error was only three out of 10,000, which surprised everyone present. According to records Magalin's bonus was 0 yuan. Since then, many people have imitated this kind of touch typing, and schools specializing in training typists have begun to appear in the United States. ?
Due to the emergence of touch typing technology, the keystroke speed was sufficient to meet the needs of daily work. However, 60 years later (1934), a man named Dvorak in Washington artificially made the left and right hands able to type. A new arrangement method is invented by alternately typing more words. This keyboard can shorten the training cycle by 1/2 and increase the average speed by 35%. The principles of DVORAK keyboard layout are: 1. Try to hit alternately with left and right hands to avoid single-handed combos; 2. The average moving distance of keystrokes across rows is the smallest; 3. The most commonly used letters should be placed in the leading key positions. ?
More reasonable and efficient than the DUORAK keyboard is the MALT keyboard invented by Lillian Malt. It changes the original staggered rows of keys and allows more thumb use, making the "Backspace" key and other keys that are originally far away from the center of the keyboard easier to reach. However, MALT keyboards require special hardware to be installed on computers, so they are not widely used. ?
By the mid-20th century, the keyboard had another use - as the basic input device for computers. On the other hand, the "QWERTY" keyboard is still the most commonly used keyboard layout to this day. This is a very typical example of "an inferior product defeats an advantageous product".
IT Character Biography: QWERTY Keyboard Inventor--Shores
Today, the most commonly used input devices for personal computers are keyboard and mouse. ?
The universal 101-key or 102-key keyboard is named according to the arrangement of English letters and is called a QWERTY keyboard. There is no doubt that it was "born out" of the English typewriter. Bill Gates once used this keyboard to illustrate what a "de facto" standard is: "The order of letters on English typewriters and computer keyboards is QWER?TY. There is no law saying that they must be arranged this way. But they do. Effectively, most users will stick to this standard. Interestingly, this arrangement is not a reasonable layout. ?
The inventor of the QWERTY keyboard is Christopher Sholes (C. Sholes), who lived during the American Civil War in the 19th century and was the editor of the "Milwaukee News". With the assistance of his friend Saul, Shores developed a page numbering machine and obtained a patent for the invention. Glidden, a colleague at the newspaper office, suggested that he further develop the typewriter on this basis and found him experimental data from the British. ?
After years of hard work by Shores and two partners, in 1860, they made a prototype of the typewriter. However, Shores discovered to his dismay that his machine would not work properly if he typed even slightly faster. As a rule, Shores arranged the 26 English letters on the keyboard in the order of ABCDEF. In order to make the typed words one by one, the keys should not be too far apart. In this case, as long as the finger movement is slightly faster, the metal rods connecting the keys will interfere with each other.
In order to overcome the interference phenomenon, Shores rearranged the positions of the letter keys, placing commonly used letters as far apart as possible to extend the finger movement process. ?
The abnormal thinking method has been successful. Sholes excitedly typed a line of letters: "The first blessing, dedicated to all men, and especially to all ladies." Sholes "especially" dedicated his invention to women. He wanted to They created an unprecedented new profession - "typist". On June 23, 1868, the U.S. Patent Office officially accepted the typewriter invention patent jointly registered by Shores, Glidden, and Saul. ?
From today's perspective, the keyboard letter arrangement invented by Shores 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", so it is very awkward to use. Someone once made statistics that using a QWERTY keyboard, a skilled typist's fingers can move up to 25.7 kilometers in 8 hours. However, QWERTY remains the "de facto" standard for computer keyboards today. Although A. Dvorak, a professor at the University of Washington, designed the DVORAK keyboard with a more scientific key arrangement in 1932, it never became popular. The mouse was invented by American scientist Douglas Engelbart in 1964. Professor Negroponte wrote in "Digital Survival": "He originally designed the mouse to point to files, not to draw. But this invention has been passed down and can be seen everywhere today."?
Engelbart was an outstanding thinker, inventor and computer pioneer. He wrote 25 books in his lifetime and held more than 20 invention patents. He has made genius predictions and proposed theoretical frameworks in many fields such as hypertext and hypermedia systems, human-computer interaction and network technology. He spent his whole life trying to develop a computer that would increase intelligence for mankind, and the mouse was just a small invention that came with it. ?
Engelbart served as a ship radar technician during World War II and received a doctorate from the University of California, Berkeley, after the war. He often imagined that computers could display graphics like radar and control operations through joysticks. In 1964, with funding from the Defense Department's Advanced Planning and Research Agency (ARPA), Engelbart established an "Amplification Research Center" to realize his dream. In 1968, at the American Autumn Computer Conference, Engelbart demonstrated his new invention to the attendees: using a keyboard, a monitor, and a crude mouse to remotely operate a crude large computer 25 kilometers away. It caused a great sensation among those who still used punched cards for output. ?
The casing of Engelbart's prototype mouse was delicately carved from wood and had only one button instead of three like modern mice. A metal roller is installed at the bottom to control the movement of the cursor. When the patent was issued in 1970, the name of this little device was "Display System X-Y Position Indicator." Some people in the United States joke that only men would think of calling it a "mouse" because in American slang, "mouse" also means "girlfriend." ?
In 1972, Xerox's Palo Alto Research Center (PARC) developed the "Alto" microcomputer with a graphical interface, and some of the developers "jumped" from Engelbart's laboratory. People, they configure the mouse on this computer as a convenient graphics control device. In 1983, Apple followed suit by equipping their first mouse on the "Lisa" microcomputer. Since then, the mouse has gradually become an essential input device for personal computers. (n104)
At present, the negative impact of computers on human body physiology and psychology has attracted increasing attention. For this reason, it is very necessary to use computers scientifically and reduce the harm of computers and the Internet. ?
The first is to enhance self-care awareness and take appropriate breaks between work. Generally speaking, computer operators should rest for about 10 minutes after working continuously for one hour. And it is best to move your hands, feet and trunk outside the operating room. It is necessary to strengthen physical exercise, enhance physical fitness, and conduct regular physical examinations and self-psychological tests.
?
Second, pay attention to the working environment. The light in the computer room should be appropriate, not too bright or too dark, to avoid direct light shining on the fluorescent screen and causing interference. The studio should be kept ventilated and dry to eliminate harmful gases. Eject as soon as possible and try to use a non-impact printer to reduce noise. ?
Third, pay attention to the correct operating posture. The center of the computer screen should be installed at the same level as the operator's chest. It is best to use an adjustable chair. There should be enough space to stretch your feet when sitting, and do not cross your feet to avoid affecting blood circulation. ?
Fourth, pay attention to protecting your eyesight. Avoid operating the computer continuously for a long time and take breaks in between. To maintain the most appropriate posture, the distance between the eyes and the screen should be 40-50 cm, so that the eyes are looking straight or slightly downward at the screen. This can relax the neck muscles and minimize the exposed area of ??the eyeballs. If you have dry, red eyes, burning or foreign body sensation, heavy eyelids, blurred vision, or even eyeball pain or headache, you need to go to the hospital to see an ophthalmologist. ?
The fifth is to pay attention to nutritional supplements. If computer operators work in front of the fluorescent screen for too long, the rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized from vitamin A. Therefore, computer operators should eat more carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. And drink more tea, the tea polyphenols and other active substances in the tea will help absorb and resist radioactive substances. ?
Sixth, pay attention to keeping your skin clean. There is a lot of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the exposed skin of the face and hands. Over time, rashes and pigmentation are prone to occur. , severe cases may even cause skin lesions. ?
Health care for computer users?
Can computer users drink more green tea and chrysanthemum tea?
In addition to being exposed to more electromagnetic radiation, computer users also suffer from computer fluorescent screens. Flashing also has a strong irritating effect on the eyes. ?
Those who use computers for a long time are prone to eye diseases. Experts believe that drinking more green tea can have a certain anti-radiation effect. In addition, chrysanthemum is very effective in treating eye fatigue and blurred vision. For computer users who often feel their eyes are dry, drinking more chrysanthemum tea is beneficial and harmless. ?
Many people know that long-term computer use can affect health. ?
Computer users are prone to varicose veins of the lower limbs, cervical spondylosis, lumbar disc herniation and eye diseases. ?
The eyes are in a state of tension?
Because computer users sit in front of the computer for a long time and look at things closer, forcing the ciliary muscles of the eyes to be in a state of contraction and tension, thus making the lens convex to adapt When looking at near objects, the eyes are in a state of tension for a long time without rest, which will lead to myopia. Excessive visual fatigue can also cause obstruction of aqueous humor, which can easily lead to glaucoma. At the same time, dry eye syndrome, cataracts, corneal ulcers and retinal detachment are also eye diseases that people who use computers for a long time are susceptible to. ?
In addition to being exposed to electromagnetic radiation, computer users also have a strong irritating effect on the eyes caused by the flickering of computer screens, causing symptoms such as tears, vision loss, and dizziness. ?
The anti-radiation effect of green tea?
Experts believe that drinking more green tea can have a certain anti-radiation effect. "Shen Nong's Materia Medica" includes tea among 365 kinds of medicines, and says that "tea tastes bitter, and drinking it makes people think better. It helps to lie down less, lighten the body and improve eyesight."?
Experts believe that green tea contains Vitamin C and vitamin E, especially tea polyphenols, have strong antioxidant activity and can scavenge oxygen free radicals in the human body, thereby resisting radiation and enhancing the body's immunity. ?
In addition, tea contains carotene, which can be converted into vitamin A under the action of the intestinal wall and liver. Vitamin A can nourish the eyes, relieve eye fatigue, and prevent night blindness. ?
Make the brain more agile?
Not long ago, British scientists discovered that drinking tea can prevent the synthesis of an enzyme in the human body that destroys the transmission of information between brain cells. The medium of acetylcholine. Therefore, drinking tea has another benefit of making the brain more agile for office workers who often use computers. ?
Medical reports in the past have shown that more than 700 known compounds have been isolated and identified in tea, including proteins, fats, sugars and polyphenols, saponins, alkaloids, and theanine. Acids, pigments, aromatic substances, etc.
?
Chrysanthemum tea cares for eyes?
In addition, computer users can also use chrysanthemum tea to "care" for their eyes. The Chinese have known since ancient times that chrysanthemum has the effect of protecting eyes. Chrysanthemum has a good effect on treating eye fatigue and blurred vision. ?
Chrysanthemum tea with wolfberry?
"Compendium of Materia Medica" records that chrysanthemum is "sweet in nature and cold in taste, and has the effects of dispersing wind and heat, calming the liver and improving eyesight." Modern pharmacology shows that chrysanthemum is rich in vitamin A, which is an important substance for maintaining eye health. Chrysanthemum tea can make people clear-headed and bright-eyed. It is especially effective for dry eyes caused by excessive liver fire and excessive eye use. For computer users who often feel that their eyes are dry, drinking more chrysanthemum tea is beneficial and harmless. ?
The way to drink chrysanthemum tea is simple. Just soak or boil the dried chrysanthemums available on the market. You can drink one or two cups of chrysanthemum tea regularly to achieve eye health. If you drink three to four cups of chrysanthemum tea every day, it will also help your eyesight. ?
Some people also like to add wolfberry to chrysanthemum tea. The brewed tea is the famous "chrysanthemum and wolfberry tea", which has a higher eye-protecting effect, because chrysanthemum and wolfberry are both eye-protecting medicinal materials in traditional Chinese medicine. . ?
It is worth noting that chrysanthemum is cool in nature, people with weak constitution, usually afraid of cold, and prone to cold hands and feet should not drink it often, but should drink it in moderation. ?

The anti-radiation effect of green tea?
Experts believe that drinking more green tea can play a certain anti-radiation effect. "Shen Nong's Materia Medica" includes tea among 365 kinds of medicines, and says that "tea tastes bitter, and drinking it makes people think better. It helps to lie down less, lighten the body and improve eyesight."?

Beware of computer hazards?
In OFFICE, computers are our most important office supplies. It is hard to imagine how we would work without computers. But unfortunately, while we enjoy all the conveniences that computers bring us, we also have to accept the threats it poses to our health, both physically and mentally. Therefore, understanding computer "diseases" and preventing and curing computer "diseases" have become our urgent tasks. In order to fully understand the negative impact of computers on OLs' physical and mental health, we specially organized this planning to comprehensively introduce tips and methods to alleviate the eight major computer "diseases" that OLs are most difficult to escape. ?
Crime 1: Electromagnetic radiation?
Symptoms: insomnia, endocrine disorders?
Cause of disease: The monitor is too hot, which will occur while working A considerable amount of electromagnetic radiation will ionize the air, continuously generate positive charges (positive ions), and constantly neutralize the negative ions in the air, resulting in the content of negative ions being almost zero. The more negative ions are beneficial, the more positive ions are harmful. If you are exposed to an environment with too many positive ions for a long time, they enter the lungs through breathing and are then transported to various tissues of the human body along with the blood circulation, making the blood and body fluids acidic and delaying the normal functioning of the body. Metabolic function causes toxins to accumulate in the body. It can cause insomnia, decreased immunity, and female endocrine disorders. ?
Mitigation methods?
1. Carefully clean the office environment. Because positive ions will be firmly adsorbed on dust particles, the more dust, the more positive ions. ?
2. Drink more tea. Tea polyphenols and other active substances contained in tea can help absorb radioactive substances. ?
3. Most of the radiation emitted by the monitor does not come from its front, but from the sides and back. Therefore, don't point the back of your monitor toward the back of your colleague's head or the side of your body. ?
4. Drink green tea often. Green tea is the most popular health drink in recent years because it contains powerful antioxidants catechol and vitamin C, which not only can remove free radicals in the body, but also cause the adrenal cortex to secrete antioxidants to fight stress. Hormones can greatly improve mood and irritability. However, it is best to drink it during the day so as not to affect your sleep. ?
5. Mung beans can clear away heat and detoxify, diuresis and reduce swelling, while barley can strengthen the spleen, stop diarrhea, lighten the body and replenish qi. When you often need to stay up late to work or are upset, dry mouth, or constipated, Very helpful in eliminating irritability. ?
6. Washing your face frequently can prevent radiation waves from irritating your skin. ?
7. Place a pot of plants or water under the computer desk to absorb the electromagnetic waves emitted by the computer. ?
8. Try to use LCD monitors. ?
9. Wear a radiation-proof bellyband. ?
Crime 2: Dust field?
Symptom: Skin allergy?
Cause of disease: An electrostatic field will be formed around the monitor when it is turned on. It will almost inhale the dust suspended in the air of the entire room into its own field, which will irritate the facial skin and cause allergic rashes and other phenomena. When sitting in front of a computer, the air around you is filled with a large amount of dust particles. Therefore, the user's skin is very prone to allergic reactions such as rashes. ?
