On the first page of this section, one of the keyboard layouts I showed was a typical layout for a three-bank manual typewriter.
1 2 3 4 5 6 7 8 9 0 Q W E R T Y U I O P @ $ % ! _ * / - # A S D F G H J K L ( ) ? ' " : ; & Z X C V B N M , .
This is the keyboard arrangement found on a Corona typewriter. Other typewriters used different arrangements of characters.
For example, some later Blickensderfer typewriters used this arrangement of characters:
" # $ % _ & ' ( 0 ) Q W E R T Y U I O P / - ¢ ; : ! ^ 1 A S D F G H J K L . 2 3 4 5 6 7 8 9 Z X C V B N M ? ,
The Blickensderfer was a manual typewriter that had an interchangeable typewheel, thus providing the flexibility of changing between different styles of type on a single machine long before the IBM Selectric typewriter was invented. But unlike the Selectric, I suspect that the mechanism of this typewriter hampered the speed of typing compared to that on conventional manual typewriters.
Be that as it may, another thing that likely greatly hampered the popularity of the Blickensderfer typewriter was that most of them had a keyboard layout like this:
" ( ) _ ; * ' : Z X K G B V Q J % / - ¼ ! ½ + ¾ = £ & P W F U L C M Y ? . , 1 2 3 4 5 6 7 8 9 0 D H I A T E N S O R
It would appear to me that it was intended that on this type of keyboard, the bottom row of keys, rather than the middle row, was to serve as the home row. This makes sense on a three-bank keyboard, since even the double up-reach to where the number keys are on a four-bank keyboard is easier than a down-reach.
Presumably, this arrangement of keys could be adapted to the conventional layout of a four-bank keyboard to produce something like this:
! " # $ % _ & ' ( ) * + 1 2 3 4 5 6 7 8 9 0 - = @ ? ¼ ¢ P W F U L C M Y / ½ : D H I A T E N S O R ; Z X K G B V Q J , .
Since the conventional layout of keys on a typewriter was modified to prevent typewriters from causing the typebars on a mechanical typewriter to jam from typing too fast, now that the keyboard is connected to an electronic device, the computer, it is not surprising that some have suggested that a more efficient keyboard be used with keyboards today.
In fact, since mechanical typewriters improved during their reign from the earliest model, this possibility was considered long ago.
Slightly different keyboard layouts are used in some countries speaking languages other than English which still use the Roman alphabet.
Thus, in France and Belgium, the normal keyboard layout arranges the letters in this manner:
AZERTYUIOP QSDFGHJKLM WXCVBN
and in Germany, the change is even smaller:
QWERTZUIOPÜ ASDFGHJKLÖÄ YXCVBNM
but some other countries have keyboards which involve more extensive changes.
To avoid problems dealing with accented letters not in the standard 8-bit extension to ASCII, this image illustrates the Latvian keyboard arrangement:
And, in Turkey, the standard layout for typewriters there was promulgated after extensive study of the properties of the Turkish language and of typing efficiency:
In 1937, Portugal's dictator Antonio Salazar decreed the use of the following keyboard arrangement:
¶ § " ' ( ) / % & £ ª ` 1 2 3 4 5 6 7 8 9 $ º ^ _ ´ - H C E S A R O P Z ~ ! ; ? Q T D I N U L M X , : Y Ç J B F V G K W .
which is apparently no longer in use in Portugal, that country having returned to a QWERTY-based arrangement.
In Belgium, the following keyboard arrangement, clearly developed, like the Dvorak keyboard, to permit efficient typing, was once in use:
1 3 4 5 6 7 8 § * " è à & _ ( F Z X B ! 2 ° é A E U - K G L M N P ¨ 9 / ^ O I Y : ç Q T R S C : % + = ? ´ ) ù , W J D ' H V
but as it is not offered even as an alternate keyboard now for that country by computer makers, I can only assume that it, too, has fallen into disuse.
The following diagram shows three Russian keyboard arrangements of interest, along with three keyboard arrangements for Bulgarian, which (at least at present) uses the same Cyrillic letters as Russian:
At the top of the diagram is the old Russian keyboard arrangement for typing in the old orthography.
Originally, I omitted two of the additional letters used in the old orthography, as the keyboard image I found did not include them. More recently, having seen an image of a keyboard with an arrangement like that in the second diagram, but also with a V perhaps for writing Roman numerals, I took its position as a clue to deciding where those two letters might have gone.
One of those two letters, "izhitsa", which looks like a V, sometimes with a tail on the top right, was very rarely used; according to Wikipedia, by 1901 or thereabouts, only the Russian word for myrrh was consistently spelled using that letter. The other missing letter is "fita", which looks like the Greek letter theta, and which was used in many, but not all, Russian words derived from Greek in place of the normal Russian letter F which looks like the Greek letter phi. Wikipedia notes that some Russian words derived from Greek went and used T instead to replace theta.
The second diagram shows an early Russian keyboard for the new orthography, where the positions of the letters which were removed were simply reused; only the hard sign was moved.
The third diagram shows a modern Russian typewriter for the new orthography. Instead of moving other letters into the vacated spaces, the whole row of letters to the right of two of the vacated spaces is moved one position to the left, which changed the keyboard arrangement enough to require people to learn to type again.
The fourth diagram shows the modern standard Bulgarian keyboard arrangement.
The fifth diagram shows an example of the keyboard on a Bulgarian typewriter which predated that modern standard; the character "yerry" is handled differently, being available in upper-case on the older arrangement, and a couple of other letters are moved around: the letter F is almost exchanged with "yerry", but not in exactly the same position on the bottom row, and so "e oborotnoye" is moved over one position.
And then the sixth diagram shows a keyboard in which "yerry" is entirely omitted, but where an additional letter, "yus", unique to Bulgarian, is present in the position used for Q on a QWERTY keyboard, and, in addition, the letter "yat", also found in old orthography Russian, is also present.
Just as on many English-language typewriters, one had to use the lowercase L for the numeral 1, note how both the capital letter O and the Russian capital letter for Z are used for numerals, 0 and 3 respectively. This was also done on many Armenian-language keyboard layouts:
The diagram above shows the Armenian-language keyboard layouts offered by the Royal, Olympia, and Underwood companies respectively, followed by my attempt to reconstruct the keyboard arrangement of typewriters used in Soviet Armenia, based on a comment that Microsoft had mixed up two letters in their Eastern Armenian keyboard, and some inferences of my own concerning numbers and punctuation. Note that the arrangement of the letters matches that of the Olympia typewriter in part.
Olympia offered two variations of their Armenian keyboard; the other one is the arrangement depicted on the top of this diagram:
While that arrangement is not too much different from the other one of theirs depicted above, it more closely resembles the second arrangement in this diagram; this one, found on a typewriter made by Royal, while it resembles the Olympia arrangement more than their own, follows the Underwood one in avoiding replacing the digits 2 and 3 by the Armenian letters that resemble them - and, thus, is a potentially more useful keyboard arrangement in our computer age.
If one took the Eastern Armenian keyboard and modified it in the same way that this arrangement by Royal modified the Olympia one, one could get a keyboard like this:
based on the physical layout of the Japanese keyboard, but with a normal spacebar. Unfortunately, Armenia is too small a market for manufacturers to feel that even so small a degree of retooling for just that market would be worth it.
Given that keyboards without enough room for the Armenian alphabet and the ten digits seem to be inevitable, I would at least recommend the following two measures:
rather than using the Alt key to access digits on the top row.
In the infancy of the typewriter, many different manufacturers had their own keyboard arrangements, such as the DHIATENSOR arrangement used with the Blickensderfer shown above. And many more efficient alternatives to the QWERTY keyboard have been proposed over the years, and new ones are still being invented. Even programs to begin with a starting keyboard layout and make changes to it to produce a more optimum keyboard are offered by more than one site.
But, of course, the only more efficient keyboard arrangement to achieve any significant recognition is the Dvorak keyboard layout:
7531902468= ?,.PYFGCRL/ AOEUIDHTNS- ,QJKXBMWVZ
in its original form, and
1234567890 ',.PYFGCRL/=\ AOEUIDHTNS- ;QJKXBMWVZ
as commonly used today.
While I do feel the prospects for any simplified keyboard layout other than Dvorak are quite dim, still, I will note that if I were to approach the design of a more efficient keyboard in a simplistic fashion, I might come up with something like this:
,.HSYFCMWG OIAEULTNRD ;/JXZQKVBP
based primarily on individual letter frequencies, but also giving the letters H, S, and Y to the left hand because they are somewhat more likely to be found together with other consonants than many other consonants. This is also slightly true of Z, while Q invariably precedes U, confirming the decision to follow frequency instead of alphabetical order.
However, none of the alternative keyboard arrangements I've encountered seem to resemble this one very much, so presumably I have not given enough weight to some more sophisticated variables impinging on typing speed.
Of course, on the theory that just about anything is better than QWERTY, the arrangement:
,.KLMNOPQR ABCDEFGHIJ ;/STUVWXYZ
would at least be easy to memorize; and, by departing slightly from plain alphabetical order by putting the first letters in the middle row, it still makes an effort to make the most frequent letters the easiest to reach. Of course, swapping the two letters D and E would be an obvious further improvement. (Could the result be called the abecedarian keyboard?)
Or, one could go with:
,CGUVWQ789 .DHK;/P456 AEILMNORST BFJXYZ0123
to make use of the regular spacing of the first three vowels in the alphabet, but it isn't really clear that the form of alphabetic order visible in this arrangement will really help all that much in memorizing it. Sneaking a numeric keypad arrangement for the numbers into the design is, at least, interesting.
But, as noted, it is enough trouble to bother with any keyboard arrangement other than QWERTY for improved typing speed; at least Dvorak has a modicum of recognition, and would seem to be the only alternate keyboard arrangement worth bothering with on a normal keyboard. Of course, while this is true for regular keyboards, for other types of keyboard, arrangements such as the FITALY keyboard for stylus entry, or the ergonomic Maltron keyboard, or a pure alphabetic arrangement of keys for devices with keypads too small for touch-typing, can have a valid place.
The keyboard on the IBM Personal Computer was designed to offer an important feature to avoid frustration while typing. The keyboard was constantly scanned by sophisticated circuitry which sent one code to the computer when a key was depressed, and another code when the key was released.
Quite early in the life of the IBM PC, someone made a keyboard overlay and software so that two rows of keys on the PC keyboard could be used as a piano keyboard, thanks to this feature.
Could someone make software for the PC so that one could, by pressing several keys at once, type, say, an entire English syllable?
So, to type the word "strengths", from left to right on the keyboard, one might press the left "s" key, the "t" key, the "r" key, the "e" key, the "ng" key, the "th" key, and the right "s" key.
Some keyboards have been made like this.
Of the three keyboards I will note of this type, the first is the Stenotype keyboard, used for court reporting. It is described in U.S. Patent 1,143,160, from the year 1915. Alice M. Anderson is the inventor. This keyboard is noted by (1) in the diagram at the left.
Four keys represent vowels, and they are operated with the thumb; this is a factor common to the two other keyboards I will discuss later, and as it seems to me that having the thumbs operate the vowel keys is an unavoidable feature of a syllable chord keyboard, it seems to prevent providing such a keyboard using only software.
This type of keyboard remains in use for court reporting to the present day. As the Wikipedia article on it notes, individual users of this type of keyboard may use their own combinations of letters that do not normally occur together in syllables to stand for consonants not shown on the machine. Because this means the use of this type of keyboard is of a personalized nature, I was not surprised that I did not initially turn up references to attempts made to adapt it to computer data entry, but later I did find that at least one company, Advantage Software, appears to have developed closed-captioning systems, and other related products, based on this type of keyboard.
Also, the asterisk appears to be used to indicate that voiced consonants are to be replaced by their unvoiced counterparts.
In Britain, a different keyboard design is often used for court reporting. This keyboard is known as the Palantype keyboard. This keyboard is described in U.S. Patent 2,318,519, issued in 1943. The inventor was Clementine Camille Marie Palanque. It is indicated by (2) in the diagram at left.
As there were three rows of consonants instead of two rows, the key combinations for the less used letters were standardized on this keyboard, and so while in its original form, each syllable was represented by a row of letters each of which was either present or not in its own position in the row, as with the Stenotype, electronic versions of this keyboard were made which used a large dictionary of the words of English to produce output with conventional spelling. The BBC used this method for real-time closed captioning of television shows, and keyboards of this type are also used in Britain for the hearing-impaired to communicate. The company supplying keyboards of this type in Britain, Possum Controls Limited, recently closed down, but licensed its technology so that it would remain available to hearing-impaired individuals there.
The dot indicates that the vowel should be long, and the plus signs on each half of the keyboard indicate that the unvoiced consonant on that side of the syllable is to be replaced by its voiced counterpart.
Still later, another type of keyboard, first known by its original trademark, Velotype, and currently available under the Veyboard name, was developed. This is described in U.S. Patent 4,804,279, granted in 1989. Its inventors were Nicolaas M. Berkelmans and Marius Den Outer, and was assigned to the Dutch company Special Systems Industry B.V., and is indicated by (3) in the diagram at left.
This keyboard also operates on the basic principle of the fingers of the left hand indicating the consonants before the vowel, the thumbs the vowel, and the fingers of the right hand indicating the consonants after the vowel. But it was not designed for court reporting, and was designed from the beginning to facilitate entry of text with normal spelling. The patent describes how the interpretation of the keys of the keyboard is modified so that it can be used with English, Dutch, or German.
While it was originally sold as a generally useful keyboard for anyone who would like to type text on a PC more quickly, limited demand has led to its price going up, and the information I have seen implies that its remaining users are largely Dutch TV stations, for their closed captioning. It had been used in the U.S. and other countries both for that purpose and for other purposes in its heyday.
Like the Palantype, this keyboard also had three rows of consonants for the fingers. Except for A and U, it had two complete sets of vowels so that the spelling of dipthongs could be indicated, but they are located where a finger, not the thumb, reaches them.
Syllable chord keyboards appear not to have been particularly successful, except in niche applications, and this is, of course, not particularly surprising in view of the amount of training that is required to use them successfully.
It occurs to me, however, that a conventional ergonomic keyboard design could be modified by splitting the space bar into two keys, and adding some keys below it and perhaps above it as well to allow the keyboard to optionally be used as a syllable chord keyboard. With four rows of keys for the fingers, instead of two or three, perhaps the design could be simplified so as to reduce the learning curve significantly, even if that meant the typing speeds achievable would not be quite as high as with previous designs.
The large keys for changing capitalization and spacing on the Velotype or Veyboard are meant to be operated by the forearms; to have such keys on the type of keyboard I am describing, and yet have them out of the way when the keyboard is used conventionally, one could have a bar that swings out of the way, linking two small keys (which could be mechanically linked underneath, like the sides of a space bar on many computer keyboards).
Thus, one would start from a typical ergonomic keyboard design:
modify it so that the amount by which the rows of keys are staggered is uniform:
change the shape of the keys, so that it is possible for one finger to easily press two keys that are adjacent in the same column, and add the additional keys required for chord keyboard usage:
and finally, develop the arrangement of keys required for such usage:
The home locations of the fingers would remain the same as when the keyboard is used conventionally, on the keys that on the QWERTY layout correspond to (A S D F) and (J K L ;). Up to six consonant sounds might occur in a syllable, and the fingers that indicate them would be (A)(SD)(F) before the vowel and (J)(KL)(;) after the vowel. So most consonants would be indicated by the (SD) and (KL) fingers; the other fingers would be used for those which combine before or after other consonants.
If necessary, the fingers which rest on the S and K keys would be used to "shift" the meanings of the keys struck by the fingers from the D and L keys respectively to allow more than fourteen consonants to be present in the middle position of a consonant cluster.
Some combinations of consonants, such as TH and NG, would be treated as single letters; this would also be true for QU on the left-hand side of the keyboard.
My goal is to make a chord keyboard that can be used as a normal keyboard, and which is simple to learn, to allow people to try getting started with this approach without a large up-front investment in effort.
