Dvorak proponents claim that it requires less finger motion and as a result reduces errors, increases typing speed, reduces repetitive strain injuries, or is simply more comfortable than QWERTY. Dvorak has failed to replace QWERTY as the most common keyboard layout, with the most pointed-to reasons being that QWERTY was popularized 60 years prior to Dvorak's creation, and that Dvorak's advantages are debated and relatively small.

Overview

speeds with respect to the QWERTY layout by alleviating some of its perceived shortcomings, such as: * Many common letter combinations require awkward finger motions. * Some common letter combinations are typed with the same finger. (e.g. "ed" and "de") * Many common letter combinations require a finger to jump over the home row. * Many common letter combinations are typed with one hand while the other sits idle (e.g. was, were). * Most typing is done with the left hand, which for most people is not the dominant hand. * About 16% of typing is done on the lower row, 52% on the top row and only 32% on the home row. August Dvorak studied

of the hand and created a new layout to alleviate the above problems, based on the following principles: * Letters should be typed by alternating between hands (which makes typing more rhythmic, increases speed, reduces error, and reduces fatigue). On a Dvorak keyboard, vowels and the most used symbol characters are on the left (with the vowels on the home row), while the most used consonants are on the right, just like how the

, where the fingers rest, and under the strongest fingers. (About 70% of letter keyboard strokes on Dvorak are done on the home row and only 22% and 8% on the top and bottom rows respectively.) * The least common letters should be on the bottom row which is the hardest row to reach. * The right hand should do more of the typing because most people are right-handed. *

s should not be typed with adjacent fingers. *Stroking should generally move from the edges of the board to the middle. An observation of this principle is that, for many people, when tapping fingers on a table, it is easier going from little finger to index than vice versa. This motion on a keyboard is called ''inboard stroke flow''. The Dvorak layout is intended for the English language, since other European languages have letter frequencies, letter sequences, and bigrams differing from those of English. Also, many languages have letters that do not occur in English. For non-English use, these differences lessen the alleged advantages of the original Dvorak keyboard. However, the Dvorak principles have been applied to the design of keyboards for other languages, though the primary keyboards used by most countries are based on the QWERTY design. The layout was completed in 1932 and granted in 1936. The

had come into wide use by that time and Dvorak became interested in the layout while serving as an advisor to Gertrude Ford, who was writing her master's thesis on typing errors. He quickly concluded that the QWERTY layout needed to be replaced, as QWERTY had not been laid out with the pure intention of ease and speed. Dvorak was joined by his brother-in-law William Dealey, a professor of education at the then North Texas State Teacher's College in

. Dvorak and Dealey's objective was to scientifically design a keyboard to decrease typing errors, speed up typing, and lessen typist fatigue. They engaged in extensive research while designing their keyboard layout. In 1914 and 1915, Dealey attended seminars on the science of motion and later reviewed slow-motion films of typists with Dvorak. Dvorak and Dealey meticulously studied the English language, researching the most used letters and letter combinations. They also studied the physiology of the hand. The result in 1932 was the Dvorak Simplified Keyboard. In 1893, George Blickensderfer had developed a keyboard layout for the Blickensderfer typewriter model 5 that used the letters ''DHIATENSOR'' for the home row. Blickensderfer had determined that 85% of English words contained these letters. The Dvorak keyboard uses the same letters in its home row, apart from replacing ''R'' with ''U'', and even keeps the consonants in the same order, but moves the vowels to the left: ''AOEUIDHTNS''. In 1933, Dvorak started entering typists trained on his keyboard into the International Commercial Schools Contest, which was a typing contest sponsored by typewriter manufacturers consisting of a series of professional and amateur contests. The professional contests had typists sponsored by typewriter companies to advertise their machines. In the 1930s, the Tacoma, Washington, school district ran an experimental program in typing designed by Dvorak to determine whether to hold Dvorak layout classes. The experiment put 2,700 high school students through Dvorak typing classes and found that students learned Dvorak in one-third the time it took to learn QWERTY. When a new school board was elected, however, it chose to terminate the Dvorak classes. During World War II, while in the Navy, Dvorak conducted experiments which he claimed showed that typists could be retrained to Dvorak in a mere 10 days, though he discarded at least two previous studies which were conducted and whose results are unknown. With such great apparent gains, interest in the Dvorak keyboard layout increased by the early 1950s. Numerous businesses and government organizations began to consider retraining their typists on Dvorak keyboards. In this environment, the

commissioned Earle Strong to determine whether the switch from QWERTY to Dvorak should be made. After retraining a selection of typists from QWERTY to Dvorak, once the Dvorak group had regained their previous typing speed (which took 100 hours of training, more than was claimed in Dvorak's Navy test), Strong took a second group of QWERTY typists chosen for equal ability to the Dvorak group and retrained them in QWERTY in order to improve their speed at the same time the Dvorak typists were training. The carefully controlled study failed to show any benefit to the Dvorak keyboard layout in typing or training speed. Strong recommended speed training with QWERTY rather than switching keyboards, and attributed the previous apparent benefits of Dvorak to improper experimental design and outright bias on the part of Dvorak, who had designed and directed the previous studies. However, Strong had a personal grudge against Dvorak and had made public statements before his study opposing new keyboard designs. After this study, interest in the Dvorak keyboard waned. Later experiments have shown that many keyboard designs, including some alphabetical ones, allow very similar typing speeds to QWERTY and Dvorak when typists have been trained for them, suggesting that Dvorak's careful design principles may have had little effect because keyboard layout is only a small part of the complicated physical activity of typing. The work of Dvorak paved the way for other optimized

Original layout

Over the decades, symbol keys were shifted around the keyboard resulting in variations of the Dvorak design. In 1982, the
American National Standards Institute The American National Standards Institute (ANSI ) is a private nonprofit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organiz ...
(ANSI) implemented a standard for the Dvorak layout known as ANSI X4.22-1983. This standard gave the Dvorak layout official recognition as an alternative to the QWERTY keyboard. The layout standardized by the ANSI differs from the original or "classic" layout devised and promulgated by Dvorak. Indeed, the layout promulgated publicly by Dvorak differed slightly from the layout for which Dvorak & Dealey applied for a patent in 1932most notably in the placement of Z. Today's keyboards have more keys than the original typewriter did, and other significant differences existed: * The numeric keys of the classic Dvorak layout are ordered: 7531902468 (an order used today in the "Programmer Dvorak" layout) * In the classic Dvorak layout, the question mark key ? is in the leftmost position of the upper row, while the slash key / is in the rightmost position of the upper row * For the classic Dvorak layout, the following symbols share keys (the second symbol being printed when the hiftkey is pressed): ** colon : and question mark ? ** ampersand & and slash / Modern U.S. Dvorak layouts almost always place ; and : together on a single key, and / and ? together on a single key. Thus, if the keycaps of a modern keyboard are rearranged so that the unshifted symbol characters match the classic Dvorak layout then the result is the ANSI Dvorak layout.

), the user could be forced to switch layouts depending on the application. Occasionally, stickers were provided to place over the keys for these layouts. However, IBM-compatible PCs used an active, "smart" keyboard. Striking a key generated a key "code", which was sent to the computer. Thus, changing to an alternative keyboard layout was accomplished most easily by simply buying a keyboard with the new layout. Because the key codes were generated by the keyboard itself, all software would respond accordingly. In the mid to late 1980s, a small industry for replacement PC keyboards developed; although most of these were concerned with keyboard "feel" and/or programmable macros, there were several with alternative layouts, such as Dvorak.

operating systems from the 1986 version 1.2 onward allow the user to modify the keyboard layout by using the setmap command line utility with "usa2" as an argument, or later in 3.x systems by opening the keyboard input preference widget and selecting "Dvorak". Amiga systems versions 1.2 and 1.3 came with the Dvorak keymap on the Workbench disk. Versions 2.x came with the keymaps available on the "Extras" disk. In 3.0 and 3.1 systems, the keymaps were on the "Storage" disk. By copying the respective keymap to the Workbench disk or installing the system to a hard drive, Dvorak was usable for Workbench application programs.

In May 2004, Microsoft published an improved version of its Keyboard Layout Creator (MSKLC version 1.3 – current version is 1.4) that allows anyone to easily create any keyboard layout desired, thus allowing the creation and installation of any international Dvorak keyboard layout such as Dvorak Type II (for German), Svorak (for Swedish) etc. Another advantage of the Microsoft Keyboard Layout Creator with respect to third-party programs for installing an international Dvorak layout is that it allows creation of a keyboard layout that automatically switches to standard (QWERTY) after pressing the two hotkeys (SHIFT and CTRL).

Another third-party developer offered a utility program called MacKeymeleon, which put a menu on the menu bar that allowed on-the-fly switching of keyboard layouts. Eventually, Apple Macintosh engineers built the functionality of this utility into the standard system software, along with a few layouts: QWERTY, Dvorak, French (

), and other foreign-language layouts. Since about 1998, beginning with Mac OS 8.6, Apple has included the Dvorak layout. It can be activated with the Keyboard Control Panel and selecting "Dvorak". The setting is applied once the Control Panel is closed out. Apple also includes a Dvorak variant they call "Dvorak – Qwerty ⌘". With this layout, the keyboard temporarily becomes QWERTY when the Command (⌘/Apple) key is held down.

and may make the transition easier. Mac OS and subsequently Mac OS X allow additional "on-the-fly" switching between layouts: a menu-bar icon (by default, a national flag that matches the current language, a 'DV' represents Dvorak and a 'DQ' represents Dvorak – Qwerty ⌘) brings up a drop-down menu, allowing the user to choose the desired layout. Subsequent keystrokes will reflect the choice, which can be reversed the same way. Mac OS X 10.5 "Leopard" and later offer a keyboard identifier program that asks users to press a few keys on their keyboards. Dvorak, QWERTY and many national variations of those designs are available. If multiple keyboards are connected to the same Mac computer, they can be configured to different layouts and use simultaneously. However should the computer shut down (lack of battery, etc.) the computer will revert to QWERTY for reboot, regardless of what layout the Admin was using.

requires typists to rest their fingers in home position (on QWERTY, the "ASDF" and "JKL;" keys). The row containing said keys is called the home row. The more strokes there are in the home row, the less movement the fingers must do, thus allowing a typist to type faster, more accurately, and with less strain to the hand and fingers. According to letter frequency analysis, the majority of the Dvorak layout's key strokes (70%) are done in the home row, claimed to be the easiest row to type because the fingers rest there. Additionally, the Dvorak layout requires the fewest strokes on the bottom row (the most difficult row to type). By contrast, QWERTY requires typists to move their fingers to the top row for a majority of strokes and has only 32% of the strokes done in the home row. Because the Dvorak layout concentrates the vast majority of key strokes to the home row, the Dvorak layout uses about 63% of the finger motion required by QWERTY, which is claimed to make the keyboard more ergonomic. Because the Dvorak layout requires less finger motion from the typist compared to QWERTY, some users with repetitive strain injuries have reported that switching from QWERTY to Dvorak alleviated or even eliminated their repetitive strain injuries; however, no scientific study has been conducted verifying this. The typing loads between hands differs for each of the keyboard layouts. On QWERTY keyboards, 56% of the typing strokes are done by the left hand. As the right hand is dominant for the majority of people, the Dvorak keyboard puts the more often used keys on the right hand side, thereby having 56% of the typing strokes done by the right hand.


Awkward strokes

Awkward strokes are undesirable because they slow down typing, increase typing errors, and increase finger strain. The term hurdling refers to an awkward stroke requiring a single finger to jump directly from one row, over the home row to another row (e.g., typing "minimum" hich often comes out as "minimun" or "mimimum"on the QWERTY keyboard). In the English language, there are about 1,200 words that require a hurdle on the QWERTY layout. In contrast, there are only a few words requiring a hurdle on the Dvorak layout (e.g. "spiky", where the "piky" is typed entirely on the left pointer finger; it corresponds to ";rgvt" on QWERTY).


Hand alternation and finger repetition

It is claimed that words involving both hands can be typed faster than words involving only one hand, and with more hand alternation there is, the faster it can be typed. This improvement comes from splitting the workload more evenly between the two hands. The QWERTY layout has more than 3,000 words that are typed on the left hand alone and about 300 words that are typed on the right hand alone (the aforementioned word "minimum" is a right-hand-only word). In contrast, with the Dvorak layout, only a few words are typed using only the left hand and even fewer use the right hand alone. This is because most syllables require at least one
vowel A vowel is a speech sound pronounced without any stricture in the vocal tract, forming the nucleus of a syllable. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness a ...
, and, in a Dvorak layout, all the vowels (and "y") fall on the left side of the keyboard. However, this benefit dwindles for longer words, because one English syllable can contain numerous consonants (as in "schmaltz" or "strengths").


Standard keyboard

QWERTY enjoys advantages with respect to Dvorak due to the fact that it is the de facto standard keyboard: *Keyboard shortcuts in most major operating systems, including Windows, are designed for QWERTY users, and can be awkward for some Dvorak users, such as Ctrl-C (Copy) and Ctrl-V (Paste). However, Apple computers have a "Dvorak – Qwerty ⌘" setting, which temporarily changes the keyboard mapping to QWERTY when the command (⌘) key is held, and Windows users can replicate this setting using

scripts. *Some public computers (such as in libraries) will not allow users to change the keyboard to the Dvorak layout. *Some standardized exams will not allow test takers to use the Dvorak layout (e.g.

Some games will automatically detect the keyboard is in Dvorak and adjust keys to the Dvorak equivalent, ",AOE", while others allow the same effect with some manual tweaking; games with hard-coded keybinds that do not allow changing the keys away from WASD become practically impossible to play under Dvorak. *People who can touch type with a QWERTY keyboard will be less productive with alternative layouts until they retrain themselves, even if these are closer to the optimum. *Not all people use keyboard fingerings as specified in touch-typing manuals due to either preference or anatomical difference. This can change the relative efficiency on alternative layouts.


Variants


One-handed versions

In the 1960s, Dvorak designed left- and right-handed Dvorak layouts for touch-typing with only one hand. He tried to minimize the need to move the hand from side to side (lateral travel), as well as to minimize finger movement. Each layout has the hand resting near the center of the keyboard, rather than on one side: the index finger rests on E and the pinky on D. Because the layouts require less hand movement than layouts designed for two hands, they can be more accessible to single-handed users. The layouts are also used by people with full use of two hands, who prefer having one hand free while they type with the other. The left-handed Dvorak and right-handed Dvorak keyboard layouts are mostly each other's mirror image, with the exception of some punctuation keys, some of the less-used letters, and the 'wide keys' (Enter, Shift, etc.). Dvorak arranged the parentheses as ")(" on his left-handed keyboard, but some keyboards place them in the typical "()" reading order. Dvorak's original ")(" placement is the more widely distributed layout, and the version that ships with

. While the letters are in the same places as the regular Dvorak layout, the numbers and most symbols have been moved. The top row contains brackets, curly brackets, and parentheses positioned in a way which makes opening and closing these symbols more intuitive. Some other common programming symbols are also placed in the top row for easy access: (&%=*+!#). The numbers are in the top row as well but the Shift key must be used to type them like on typewriters. The numbers are arranged with the odds under the left hand and the evens under the right hand, as on Dvorak's original layout. Another notable change is the swap of the semicolon/colon key with the quotation/apostrophe key. Many programming languages require each line to end with a semicolon; therefore, it makes sense to put the semicolon in a spot which is easy to reach. This layout is preinstalled on some

Research on efficiency

The Dvorak layout is designed to improve touch-typing, in which the user rests their fingers on the home row. It would have less effect on other methods of typing such as hunt-and-peck. Some studies show favorable results for the Dvorak layout in terms of speed, while others do not show any advantage, with many accusations of bias or lack of scientific rigour among researchers. The first studies were performed by Dvorak and his associates. These showed favorable results and generated accusations of bias. In 1956, a study with a sample of 10 people in each group conducted by Earle Strong of the U.S.

Research published in 2013 by economist Ricard Torres found that the Dvorak was more efficient than QWERTY.


Resistance to adoption

Although the Dvorak design is the only other keyboard design registered with ANSI and is provided with all major operating systems, attempts to convert universally to the Dvorak design have not succeeded. The failure of Dvorak to displace QWERTY has been the subject of some studies.

can have other typing needs for optimization (many are very different from English). Because Dvorak was optimized for the statistical distribution of letters of English text, keyboards for other languages would likely have different distributions of letter frequencies. Hence, non-QWERTY-derived keyboards for such languages would need a keyboard layout that might be quite different from the Dvorak layout for English.


Brazilian Portuguese

There are some non standard Brazilian Dvorak keyboard designs currently in development. The simpler design (also called BRDK) is just a Dvorak layout plus some keys from the Brazilian ABNT2 keyboard layout. Another design, however, was specifically designed for

Danish

The Danish layout DanskDvorak is similar to the Norwegian.


Finnish

A FinnishDAS keyboard layout follows many of Dvorak's design principles, but the layout is an original design based on the most common letters and letter combinations of the Finnish language. Matti Airas has also made another layout for Finnish. Finnish can also be typed reasonably well with the English Dvorak layout if the letters ä and ö are added. The Finnish ArkkuDvorak keyboard layout adds both on a single key and keeps the American placement for each other character. As with DAS, the SuoRak keyboard is designed by the same principles as the Dvorak keyboard, but with the most common letters of the Finnish language taken into account. Contrary to DAS, it keeps the vowels on the left side of the keyboard and most consonants on the right hand side.


French

In French, there is a Dvorak layout, as well as the Bépo layout, designed based on Dvorak's method of analyzing key frequency. Although Bépo's placement of keys is optimised for French, the scheme also facilitates key combinations for typing characters of other European languages, Esperanto and various symbols.

Dvorak layout is the German Type II layout. It is available for Windows, Linux, and macOS. There is also the Neo layout and the de ergo layout, both original layouts that also use many of Dvorak's design principles. Because of the similarity of both languages, even the standard Dvorak layout (with minor modifications) is an ergonomic improvement with respect to the common QWERTZ layout. One such modification puts ß at the shift+comma position and the umlaut dots as a dead key accessible via shift+period (

Icelandic

An IcelandicDvorak layout exists, created by a student at Reykjavik University. It retains the same basic layout as the standard Dvorak but features special Alt-Gr functions to allow easy usage for common characters such as "þ", "æ", "ö" and dead-keys to allow the typing of characters such as "å" and "ü".


Norwegian

The Norwegian implementation (known as "'' NorskDvorak''") is similar to Parment's layout, with "æ" and "ø" replacing "ä" and "ö".


Polish

Polish propositions of a national keyboard layout smiliar to Dvorak were created in 1950s but were not introduced due to a new version of Polish Norm in 1958 with modernized QWERTZ layout.


Romanian

A Romanian version of the Dvorak layout (named ''Popak'' after the name of its inventor) was released in October 2008. It is available for both Windows and Linux.


Spanish

Three Spanish layouts exist.


Swedish

The Svorak (''Swedish Dvorak'') layout places the three extra Swedish

s ( å, ä and ö) on the leftmost three keys of the upper row, which correspond to punctuation symbols on the English Dvorak layout. This retains the original English DVORAK design goal of keeping all vowels by the left hand, including Y which is a vowel in Swedish. The displaced punctuation symbols (period and comma) end up at the edges of the keyboard, but every other symbol is in the same place as in the standard Swedish

layout, facilitating easier re-learning. The Alt-Gr key is required to access some of the punctuation symbols. This major design goal also makes it possible to "convert" a Swedish QWERTY keyboard to SVORAK simply by moving keycaps around. Unlike for Norway, there is no standard Swedish Dvorak layout and the community is fragmented. In ''Svdvorak'', by Gunnar Parment, the punctuation symbols are as they were in the English version; the first extra vowel (å) is placed in the far left of the top row while the other two (ä and ö) are placed at the far left of the bottom row.


Turkish

The Turkish F keyboard layout ( link in Turkish) is also an original design with Dvorak's design principles, however it's not clear if it is inspired by Dvorak or not. Turkish F keyboard was standardized in 1955 and the design has been a requirement for imported typewriters since 1963.


UK English

Whether Dvorak or QWERTY, a United Kingdom keyboard differs from the U.S. equivalent in these ways: the " and @ are swapped; the backslash/pipe key is in an extra position (to the right of the lower left shift key); there is a taller return/enter key, which places the hash/tilde ~key to its lower left corner (see picture). The most notable difference between the U.S. and UK Dvorak layouts is the "key remains on the top row, whereas the U.S. "key moves. This means that the query ?key retains its classic Dvorak location, top right, albeit shifted. Interchanging the ?and @keys more closely matches the U.S. layout, and the use of "@" has increased in the information technology age. These variations, plus keeping the numerals in Dvorak's idealised order, appear in the Classic Dvorak and Dvorak for the Left Hand and
Right Hand In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to and causing it to be stronger, faster or more dextrous. The other hand, comparatively often the weaker, less dextrous or simply le ...
