Description

The agile keyboard layout

Technical field

The utility model relates to a kind of agile keyboard layout.

Background technology

The letter district layout of existing English keyboard with key supporting is continued to use the English machinery typewriter layout of QWERTY in 1872 basically, this layout then is to hammer into shape owing to the too fast generation obstruction of input speed designs for the word that prevents machinery typewriter, the deviser is by spreading out 26 letters (especially Chang Yong letter to) to reduce the generation of mechanical fault, doing the cost of being paid like this is the input difficulty, the serious reduction of input speed, finger comfort level.For a reasonably alphabetical district layout, naturally should allow the highest letter of frequency of utilization be positioned at the position that the easiest quilt impacts, and the height that existing keyboard layout occurs by frequency exactly is not provided with the position of letter.For example: letter " J " is located at forefinger district, right hand base key position, belongs to the most normal use district, but proves that through the statistical study to the alphabetical frequency of occurrences of a large amount of english articles letter " J " belongs to one of 6 alphabetical VKXJQZ of minimum use in 26 letters.Equally, also there is same situation in letter " K ".See letter " T " again, statistical result showed, this letter belongs to the most normal use letter, but the setting of existing keyboard is to be responsible for impacting by left index finger, impact letter " T " and then need left index finger sidesway and outwards stretching, extension, like this because of stroke need affect wrist than length, and to be that two actions are compound cause not only time-consuming but also accuracy has also reduced, very inconvenience.Similarly also can enumerate many letters cases and arrange irrational example.In a word, existing keyboard layout is not by the alphabetical frequency of occurrences and impact complexity setting, the input difficulty when having caused English the input, and inefficiency has seriously reduced input speed.

Summary of the invention

The purpose of this utility model is: existing keyboard layout for english input is improved, to overcome the above-mentioned defective of existing keyboard layout, provided a kind of agile keyboard layout.

The agile keyboard layout, the letter district divides the triplex row setting in the key position, and it is that second row is followed successively by the 2nd, 3,4,7,8,9 key positions from left to right: N, O, T, E, A, I.

The utility model also is provided with three Windows singly-bound shortcuts for ease of operation, and is positioned at the strong district of function, and title and figure name with Microsoft itself are labeled as " Explorer ", "-", " X " respectively.Keyboard layout for english input after the improvement is compared with existing keyboard layout for english input and is had the following advantages:

1, can obtain the fastest input speed.

The complicacy of moving when fatigue strength of pointing when 2, alleviating input significantly and minimizing keystroke only need easily impact 13 or 14 basic key positions and can finish about 80% input.

Sight line focuses mostly on and arranges in the letter district when 3, importing, and has concentrated notice better, has strengthened judgment.

4, layout is easier to memory.

5, use Windows operating system more convenient, quick.

Embodiment

The technical solution of the utility model is: according to the use complexity of the frequency of occurrences of English 26 letters and each key position, key letter district and for the most alphabetical right continuous input of frequent use is optimized keyboard layout is set.The utility model does not change existing other key position of keyboard, only changes the alignment placement of 26 letters and 1 character.It is divided into two schemes.The first string is: 26 letters are divided into triplex row, and first row is followed successively by: Q, L, R, Y, J, K, G, H, D; , second row is followed successively by: C, N, O, T, W, P, E, A, I, U, the 3rd is followed successively by: Z, V, X, M, B, F, S.Second scheme is: 26 letters are divided into triplex row, and first row is followed successively by: Q, M, L, B, J, K, G, H, D; , second is followed successively by: C, N, O, T, W, Y, E, A, I, U, the third line is followed successively by: Z, V, X, R, P, F, S.These key positions constitute about two the row zones, parallel four limit to moving with ", ", ". ", "/" key, and the parallelogram in left side is tilted to the right.

In that frequently statistics program is after the frequency of occurrences of English 26 letters adds up under to all kinds of language material situations with the CalcFreq English words, the result is as follows: in this statistics, totally be the frequency of occurrences of Chinese and English 26 letters of real world, be designated as ξ.We take out the sample (choosing this three classes language material is because on behalf of three kinds of typical cases of English input, they use respectively) of three class language material-literature, science and news from overall ξ, the sample size of every class language material is all greater than 10, each sample statistics letter number average is 1,000,000.Adopt the square estimation technique for population moment, estimate population mean E (ξ), sample variance S with sample average ξ ²Estimate population variance D (ξ), Figure 11 (pressing the descending arrangement of literature sample average ξ) is seen in the sample average ξ contrast of three class language materials.The concrete data of the sample average of three class language materials and variance are as follows: literature: the total alphabetical number of statistics: 99,049,583

	The most normal use	Inferior normal use	Common	Minimum use
					Literature	ETAONIHS	RDLU	MWCFYGPB	VKXJQZ
Academic class	ETAOINSR	HLDC	UFMPWYGB	VKXQJZ
					News category	EATIOSNR	LCHD	MUPFGYWB	VKJXQZ

Wherein the tired frequency (total frequency of occurrences) of the most normal use and time normal 12 letters that use is all above 80%, and the tired frequency of 6 letters of minimum use is all less than 3%.Can find out that thus the letter of frequent use has only 12, and has 6 letters not use substantially, has shown the extremely inequality of each alphabetical frequency of occurrences.2, in addition by sample variance S ²Can find out that the common and minimum sample variance of letter of using of three class language materials is all very little, except that indivedual letters, common letter is all less than 0.06, and minimum use letter is all less than 0.02.And for the most normal use and time normal sample variance of using letter, literature is all less than 0.1, academic class is all less than 0.2, news category is big slightly, but except alphabetical H, C and I, other letters are also all less, and this illustrates the frequency of occurrences quite stable that each is alphabetical, and the mean value of the frequency of occurrences of listing in the table promptly can be used as the actual frequency of occurrences of each letter.

Thus, each alphabetical frequency of occurrences of comprehensive three class language materials is got its mean value, and we can draw each total alphabetical frequency of occurrences height order (from high to low):

E T A O I N S R H L D C Uξ 12.21 8.94 8.07 7.61 7.22 7.01 6.70 6.27 5.34 4.04 3.97 3.15 2.85

Figure 12 (arranging from high to low by total frequency of occurrences) is seen in the alphabetical frequency of occurrences contrast of each of adjusted three class language materials:

By last figure as can be seen, roughly coincide by total each alphabetical frequency of occurrences curve of the tactic three class language materials of frequency of occurrences height, just inferior normal letter some deviation a little of using, in view of the above, we can think that total frequency of occurrences just is an acceptable.

By last, we have drawn the frequency of occurrences order of 26 letters, so how each letter is arranged into corresponding key position and has just become sixty-four dollar question by the height of each alphabetical frequency of occurrences, addressing this problem the most basic principle is: the letter that frequency of utilization is high should be easy to impact, otherwise then is difficult to impact.

For common keyboard, by initial 8 the key positions of the row of placing of finger, each 8 key position of the two rows that finger stretches or withdrawal can impact, add 6 key positions that the forefinger sidesway is responsible for and constituted the letter district of 30 basic key positions, this comprises 26 letters and 4 characters, the letter district of shape parallelogram (seeing accompanying drawing 5) is exactly the common keyboard letter district that we will study, when the physilogical characteristics from the finger keystroke can be arranged into corresponding key position with each letter by each alphabetical frequency of occurrences and form improved key letter district layout by after impacting complexity discharge one order in 30 key positions for this reason.

And after this parallelogram zone is severed by its side directions from the centre, left part is made just to have formed behind the flip horizontal the more symmetrical figure (seeing accompanying drawing 3) that the parallelogram by two levels constitutes.This figure is exactly our the natural key letter district that will study (what be called nature is because be 60 degree angles approximately during people's both hands nature keystroke, and the layout of this keyboard just in time meets these characteristics).At first, the people points when keystroke and the motion conditions of palm can be divided into following four classes (from the easier to the more advanced arranging as follows by using complexity):

1) finger need not move.

2) finger moves but does not affect palm.

3) finger moves and slightly affects palm.

4) finger moves and affects by a relatively large margin palm.

Secondly, also there are following characteristics (because of thumb only is responsible for impacting space bar, so will not discuss) in finger when keystroke:

1) ordinary people's right hand is than left hand flexible (being that most Genus Homos make right-handed crowd in right-handedness crowd one custom).

2) continuously during keystroke, the two hands coordination alternate key stroke is fastest, and one hand changes and refers to take second place, and singlehanded finger together is minimum.

3) finger outwards stretches than easier the accomplishing of inside withdrawal.

4) dirigibility, endurance are successively decreased successively by forefinger, middle finger, the third finger, little finger of toe order, and have the class difference between forefinger and middle finger, the third finger, and middle finger, the third finger are again and have the class difference between the little finger of toe.

5) forefinger three refers to by force many than other with regard to dirigibility, endurance, but its length is short slightly, so sidesway, withdrawal are easier than stretching, extension, need not affect wrist.

6) not only dirigibility of little finger of toe, endurance are minimum, and length is also the shortest, so stretch and the withdrawal keystroke all is difficult to accomplish.

In conjunction with above four class situations and six characteristics, we can draw the use complexity of each key position, letter district of nature keyboard and common keyboard, see accompanying drawing 4,6.The name of each key position can be referring to accompanying drawing 3,5, and on behalf of letter, alphabetical L, the R in the name distinguish left and right side respectively, and on behalf of the letter district, U, M, D go up row, middle row and following row respectively.Elaborate with regard to getting of accompanying drawing 4,6 below:

At first we study the use difficulty or ease order of each key position, nature key letter district.Because should be left-right symmetric in the letter district, so only need research one side get final product, characteristics 1,2 can corresponding release when the keystroke according to finger for opposite side, and we select the right side at this.

We can tell some fundamental regions with the alphabetical zoning of nature keyboard earlier the four class situations that finger and palm move during according to keystroke.For first kind situation, we can draw 4 of base key positions: RM2, RM3, RM4 and RM5, i.e. the key position of right finger initial placement when keystroke, middle row's light gray areas of seeing accompanying drawing 4 right sides; For the second class situation, in conjunction with characteristics 3,5, key position RD2 that we can draw that forefinger withdrawal impacts and middle finger and nameless two key position RU3 impacting and RU4 3 the key positions altogether of stretching, we can draw 7 expansion base key positions that comprise 4 base key positions, whole light gray areas of seeing accompanying drawing 4 right sides thus; For the 4th class situation, we can draw the most awkward key position RU1, and this key position needs the forefinger sidesway, stretches and affects palm by a relatively large margin, sees the dark-grey chroma key position, the upper left corner on accompanying drawing 3 right sides.Characteristics 6 during in addition according to the finger keystroke, we draw two other the most awkward key position RU5, RD5, see the upper right corner on accompanying drawing 3 right sides and two dark-grey chroma key positions in the lower right corner; At last, we draw the common key position corresponding to the 3rd class situation, are to remove 7 expansion base key positions and 3 the most difficult use key position all the other 5 key position RU2, RM1, RD1, RD3 and RD4 in addition.So far, we are by using complexity successively alphabetical zoning to be divided into three zones: expand basic key-position area, common key-position area and the most difficult use key-position area.Next we study the use complexity of inner each the key position of each key-position area.The use complexity of each key position can be referring to the numeral size (the more little easy more use of numeral) on accompanying drawing 4 right sides.

For the expansion key-position area, the order that each key total word is responsible for impacting by forefinger, middle finger, the third finger and little finger of toe increases successively, and this is for characteristics 4.All greater than the key total word (corresponding being meant by same finger is responsible for impacting) of corresponding basic key-position area, this is for situation 2 to the key total word of non-basic key-position area.In addition, it should be noted that the key total word maximum that little finger of toe is responsible for impacting, this is because characteristics 6.

For the most difficult use key-position area, the RU1 key total word minimum in the upper left corner on accompanying drawing 4 right sides, this is that the RU5 key total word in the upper right corner on accompanying drawing 4 right sides then is for characteristics 3 less than the RD5 key total word in the lower right corner because of characteristics 4.

For common key-position area, this is because characteristics 4 to the numeral of 3 key positions of being responsible for by forefinger less than other 2 key positions, drawing of the numeral size of these 3 key positions then is that (we can think that the RD1 key position of forefinger lower-left side is than the easier use in RM1 key position in left side for characteristics 5, affect the degree of wrist a little littler because impact RD1 key position), draw then still for characteristics 4 as for the numeral of other 2 key positions.At last, according to characteristics 1 and 2, we can correspondingly draw the use complexity of each key position, nature keyboard left side, referring to the numeral size in accompanying drawing 4 left sides.

As for the use difficulty or ease order of each key position, common keyboard letter district,, be not left-right symmetric, so the use difficulty or ease that need contrast each key position of nature keyboard be done some adjustment in proper order because should left side, letter district and the natural angle when not meeting people's left hand keystroke.

At first, for the basic key-position area of expansion in left side, letter district,,, see the whole light gray areas in accompanying drawing 6 left sides so reduce the base key position of an expansion because the left index finger withdrawal impacts and do not affect that key position of wrist not exist.Secondly, for the most difficult use key-position area in left side, letter district, the key position of being responsible for impacting and affect by a relatively large margin wrist by forefinger is not or not the upper right corner in left side letter district but accompanying drawing 5 left sides dark-grey chroma key position LD5 is seen in the lower right corner.Thus, also corresponding the changing in the common key position in left side, letter district removed 6 expansion base key positions and 3 the most difficult use key position 6 key position LU4, LU5, LM5, LD2, LD3 and LD4 in addition.

Because common keyboard letter district is left-right symmetric no longer,, key position, the left and right sides need be taken all factors into consideration so the use difficulty or ease order of each key position, left side letter district no longer can be released by corresponding key position, right side simply according to characteristics 1,2.

For the basic key-position area of expansion, few one of expansion base key position, left side, numeral of so positive this expansion base key position correspondence of answering is just skipped.For common key-position area, many LD4 key positions, common key position, left side, this key position is impacted by forefinger sidesway, withdrawal, can think the RD1 key position of this key position corresponding to right side, letter district.In addition, for key position LU5, this key position by the forefinger sidesway, stretch and to impact, for characteristics 4 and 5, we can think that the use complexity of this key position is between LU4 key position and LD3 key position.Thus, we have drawn the use complexity of each key position, common keyboard letter district, see all numerals in the accompanying drawing 6.

So far, we have drawn each key position use difficulty or ease order of letter district of nature keyboard and common keyboard.How we begin to consider that use complexity with the frequency of occurrences of 26 letters and each key position, letter district combines and form letter district final layout now.

We think that best combination should meet following three principles: 1. the letter that frequency of utilization is high should be easy to impact, otherwise then is difficult to impact.2. smooth when importing continuously.3. take into account transition with existing qwerty keyboard layout.

Getting of principle 1 is conspicuous, yet the just single letter input that principle 1 solves, when the continuous input of a plurality of letters, characteristics 2 when we must be according to the finger keystroke are optimized (in order to import the more smooth key position that can exchange the letter that the frequency of occurrences is close) accordingly, and what principle 2 was considered is exactly this problem.As for principle 3, what mainly consider then is four characters and some keyboard shortcut CTRL+C, CTRL+V commonly used and the keys arrangement of CTRL+X.

What at first we need solve is the arrangement of four characters in letter district.Character in the existing qwerty keyboard layout "; " having occupied natural keyboard, to use easy degree be that to use easy degree be the 12nd key position for the 13rd key position and common keyboard; and the frequency of utilization of this character is very low; go out character is positioned over together consideration, and we can move to this character nature keyboard and common keyboard and use easy degree to be 27 RU5 key position.As for three other characters, because after their occupied key positions used easy degree comparatively to lean on, for the consideration of principle 3, we kept the key invariant position of these three characters.

On principle 1, we are arranged in the most easy-to-use key position by the letter that total frequency of occurrences is the highest, the letter of the frequency of occurrences second is arranged in the second easy-to-use key position, the rest may be inferred (skip with regard to corresponding the key position of four characters), draw the initial letter district layout of nature keyboard and common keyboard, see accompanying drawing 7,9.Our statistics drawn the frequency of occurrences at preceding 26 letter to tabulation (letter to being two continuous in English word letters), the letter of three class language materials is to frequency of occurrences height order (arranging from high to low) as follows: literature: total letter of statistics is to number: 75,528, the academic class of 464th he in er an re nd ou ha at en ed to hi it ng or is as es st ar te of me: total letter of statistics is to number: 21,390,484th he an in er re of on nd en es at or is it ti ed te ar st ha se al nt to hi news category: total letter of statistics is to number: 55,505,548in th er on he an re es or at en te st ti ar nd al nt to it se ed co is ng ri is by last, and it is right that we can draw 28 the highest letters of the frequency of occurrences: an at ar al aser en es edhe hain it isme ng ndon of or oure st seth to ti te

Characteristics according to the finger keystroke time more than 2 pairs 28 right inputs of letter be optimized and the consideration for principle 3 after, we have drawn the final letter district layout of adjusted natural keyboard and common keyboard, see accompanying drawing 8,10, next, we elaborate with regard to getting of accompanying drawing 8,10.

For natural keyboard, the key position exchange of letter C, M is for the input of letter to ME and CTRL+C keyboard shortcut, the key position exchange of letter G, Y is for the input of letter to NG, then is input for CTRL+V and CTRL+X keyboard shortcut as for the key position exchange of alphabetical V, K, X.For common keyboard, letter H, the exchange of the key position of R be for letter to TH, HE, ER, RE, HE, the input of AR and OR, letter D, the exchange of the key position of L be for letter to ND, the input of AL, letter U, the exchange of the key position of C be for letter to the input of OU and the input of CTRL+C keyboard shortcut, letter F, the exchange of the key position of M be for letter to OF, the input of ME, letter G, the key position exchange of W is for the input of letter to NG, letter V, K, the key position exchange of X is the consideration that remains for CTRL+V and CTRL+X keyboard shortcut, as for letter b, the key position exchange of J then is the consideration for principle 3.

So far, in conjunction with the use complexity of the frequency of occurrences of 26 letters and each key position, letter district and for after optimization is made in input continuously, finally drawn the letter district layout of natural keyboard and common keyboard.Natural key letter district layout by two symmetrical parallel quadrangular arraies: first row is followed successively by: Q, M, L, B, J, K, G, H, D; , second is followed successively by: C, N, O, T, W, Y, E, A, I, U, the third line is followed successively by: Z, V, X, R, P, F, S.The common keyboard letter district layout of arranging by parallelogram: first row is followed successively by: Q, L, R, Y, J, K, G, H, D; , second row is followed successively by: C, N, O, T, W, P, E, A, I, U, the 3rd is followed successively by: Z, V, X, M, B, F, S.For 3 Windows singly-bound shortcuts setting up, the singly-bound shortcut of so-called Windows refers to function key ad hoc on keyboard, be applied to relate in the window operation of Windows operating system of the later Microsoft of Windows95, only need to activate corresponding program or operation by a key.So far, existing two operations are composed with the singly-bound shortcut, it is respectively (Application) key of Windows logo (Start) key and " application program ", but only there are two still to lack a little, still have the quite high operation of some frequencies of utilization not composed with the singly-bound shortcut, particularly following three operation: Start+E (opening explorer), Start+D (minimized window) and ALT+F4 (closing the current active window), these three strong being arranged in the function key zone of operation, title and figure name with Microsoft itself, be labeled as " Explorer " respectively, "-" " X " is referring to accompanying drawing 1,2 upper right corner square frame parts.
