The keyboard has a very long history. As early as 1714, people from Britain, the United States, France, Italy, Switzerland and other countries have invented various types of typewriters. The earliest keyboards were used in those immature typewriters at that time. Up. Until 1868, the "father of the typewriter", the American Christopher Latham Sholes, obtained the patent for the typewriter model and obtained the right to operate it, and a few years later, he designed the practical form of the modern typewriter. The keyboard was standardized for the first time, the "QWERTY" keyboard.
Why standardize the keyboard 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 typing tool with a full mechanical structure, so if the typing speed was too fast, some key combinations were prone to card key problems, so Christoph Christopher Latham Sholes invented the QWERTY keyboard layout by placing the most frequently used letters in opposite directions, maximizing the time between repeated keystrokes to avoid jamming. Shoals applied for a patent in 1868, and the first commercial typewriter using this layout was successfully marketed in 1873. That's why there are today's keyboard arrangements.
QWERTY's keyboard keys are laid out in a very inefficient way. For example: Most typists are right-handed, but with 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, it is often necessary to move the finger up and down.
In 1888, an open typing competition was held in the United States. The court stenographer Ma Jialin showed his touch-typing skills according to a clear division of fingering. The error was only 3/10,000, which surprised the audience. According to records, Ma Jialin's prize was 500 US dollars. , Since then, many people have imitated this kind of touch typing, and there have also been schools in the United States that specialize in training typists.
Due to the advent of touch typing technology, the speed of keystrokes is sufficient to meet the needs of daily work. However, 60 years later (1934), a Washington man named Dvorak (Dvorak) made it possible to alternately type more words with the right and left hands. Inventing a new arrangement, this keyboard reduces training cycles by 1/2 time and increases average speed by 35%. The principles of DVORAK keyboard layout are: 1. Try to strike alternately with left and right hands to avoid one-handed combo; 2. The average moving distance of the more rows of keys is the smallest;
By the mid-20th century, the keyboard had another use—as the basic input device for computers. On the other hand, so far, the "QWERTY" keyboard is still the most used keyboard layout, which is a very typical example of "the inferior product wins the superior product".
