Keyboard Dvorak
The most common keyboard layout at the moment is QWERTY, invented in the 70s of the XIX century. The reason for this layout was the frequent "stickiness" of the keys, when arranged in alphabetical order. Simply put, the letters of most letter combinations in QWERTY were scattered far away from each other, which reduced the likelihood of “sticking”. In addition, this reduced the speed of printing, which, in general, led to the same effect. For modern realities, QWERTY is a model obsolete, but still used by most users.
With the advent of the first electric typewriters, the very meaning of using QWERTY layouts ended its existence and something more convenient for the person typing the text was asked to change. This is what Dvorak Keyboard has become. August Dvorak studied the frequency of letters and the physiology of human hands and created a layout based on the following principles:
- when typing hands should alternate as often as possible;
- for maximum speed and efficiency of recruitment, the most frequently used symbols should be typed the easiest. This means that the keys with these letters should be in the main row, where the fingers of a person are installed and in the zone of index and middle fingers;
- similarly, rare letters should be in the bottom row, the keys of which are hardest to press;
- the right hand should take on more “work”, because most people are right-handed;
- to collect digraphs with neighboring fingers is more difficult than those located far from each other.
The layout was finally developed in 1932 and in 1936 received US patent No. 2,040,248. American National Standards Institute (ANSI) in 1982, Dvorak's keyboard was designated as the standard along with QWERTY.

At the moment, most operating systems (for example, GNU / Linux, Mac OS, and Microsoft Windows) have built-in support for all versions of Dvorak's keyboard. But despite this, QWERTY is still used by the vast majority of users.
In addition, it is worth noting the presence of variants of Dvorak Keyboards, like a keyboard for one left or right hand, or a keyboard for programmers.
The only, but very significant at the moment, minus Dvorak Keyboards is multilingual. More precisely the inconvenience of using this layout for most international languages. The placement of the keys of the English alphabet does not change when transferred to another language. This is not always convenient, because grammar and language statistics may require different placement.
An interesting fact is that the Guinness Book of Records says that as of 2005, the world record for the speed of dialing belongs to Barbara Blackburn. Using the simplified layout of Dvorak, in 1985 she typed at a speed of 150 words per minute for 50 minutes, sometimes her speed rose to 170 words per minute; and for a short time, it reached a speed of 212 words per minute.
