Why are the keys of the computer arranged like this?

1.QWERTY keyboard is to slow down typing.

At first, the keyboards of typewriters were arranged alphabetically, but if the typing speed is too fast, some key combinations are prone to key sticking problems, so Christopher? Larson? Christopher latham Shoals invented the QWERTY keyboard layout. He put the most commonly used letters in the opposite direction, so as to slow down the typing speed to the maximum extent and avoid getting stuck. Grant 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.

Ironically, this keyboard arrangement, which was formed 29 years ago to slow down typing, has continued to this day. 1986 Bruce? Sir Buryvein once said in the article "Wonderful Writing Machine": "The arrangement of QWERTY is very inefficient." For example, most typists are right-handed, but on QWERTY, the left hand does 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.

2.DUORAK keyboard is much faster than QWERTY keyboard.

Augst in 1930? August dvorak invented an advanced Dolak keyboard system, in which nine most commonly used letters are listed on the keyboard. This design enables typists to type at least 3000 words without leaving the keyboard. QWERTY can only do 50 words. DUORAK reduces work intensity and improves work efficiency by reducing finger movement. With DUORAK, the typist's fingers move an average of 65,438+0 miles a day, while QWERTY moves 65,438+02 to 20 miles.

During World War II, Augst? Dolak once assembled 14 naval typists to practice Dolak. 1 month later, their speed increased by an astonishing 68%. Dolak keyboard allows the right hand to undertake 56% of the work; The most powerful finger has the largest workload; 70% typing is done in the middle column, without finger. But at that time, it coincided with the Second World War, and the war materials were scarce. This new keyboard was discontinued without asking the market.

Try the DUORAK keyboard yourself!

Windows built-in support for it. Open the control panel → keyboard, enter the input method regional setting tab, click the Add button, set the input method regional to English (USA), and find "American English -DUORAK" in the keyboard layout/input method column. Upon confirmation, all key positions have been changed. Now you have capital to improve your English typing speed. Of course, it will take time to re-adapt to the new system and train patiently to succeed.

3. A more advanced malt keyboard

Further than Dolak is Li Lian? 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.
