Description

Agile computer keyboard layout

The utility model relates to a kind of computing machine keyboard.

The letter district layout of active computer keyboard is continued to use the English power of old QWERT tool typewriter basically, this layout then is mechanical fault takes place to design owing to frequently being impacted for the word hammer that prevents machinery typewriter, the deviser attempts 26 letters are spread out to reduce the generation of mechanical fault, and doing the cost of being paid like this is the serious reduction of input speed.For a rational letter layout, naturally should allow the highest letters case of frequency of utilization in the position that is easily impacted, and the height that existing keyboard does not occur by frequency exactly is provided with the position of letter key.For example: letter " J " key 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 5 letters of minimum use in 26 letters.Equally, also there is same situation in letter " K " key.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, left index finger impacts letter " T " then needs the wrist sidesway to stretch upwards two actions of forefinger again, longer because of stroke like this, and to be that two actions are compound cause not only time-consuming but also accuracy also reduces, very inconvenience.Similarly also can enumerate many letter keys and arrange irrational example.In a word, existing keyboard exists not by the alphabetical frequency of occurrences and impacts difficulty or ease setting, has caused the inefficiency of English input, has seriously reduced input speed.

The purpose of this utility model is: the active computer keyboard layout is improved, according to the height of frequency of utilization 26 letters are arranged into corresponding suitable key position, to overcome the above-mentioned defective of existing keyboard.

The technical solution of the utility model is: the complexity of left and right finger keystroke is provided with keyboard layout in frequency height that occurs according to 26 letters in the English Typing and the keyboard.The utility model does not change existing other key position of keyboard, only changes the alignment placement of 26 letters and 1 character.26 letters are divided into triplex row, and second row is followed successively by: H, N, O, T, D, R, E, A, I, S key.On this basis, first row is followed successively by: Q, Y, F, C, K, V, U, M, W, J key, the third line are followed successively by: Z, B, P, G, X, L; Key; Also can be set to, first row is followed successively by: Q, G, W, M, X, K, C, F, Y, J key, and the third line is followed successively by: Z, V, B, P, U, L; Key, these key positions and "＜", "〉", "! " key constitutes about two the row zones, parallel four limit to moving, and the parallelogram in left side resembles right bank.

This product, also is provided with three Windows operation singly-bounds, and is positioned at function key area for ease of operation with novel, can " Explorer ". and "-". " X " mark.

Computer keyboard after the improvement is compared with existing computer keyboard and is had the following advantages:

1. can obtain input speed faster.

2. the complicacy of moving when alleviating the fatigue strength of pointing in the input significantly and reducing keystroke, only need easily impact the base key position just can finish most of input service.

3. side-looking has been avoided in the positive aspect of central authorities in the eyes many places in the input, has concentrated notice better, has strengthened judgment.

4. layout is more convenient for remembering.

5. use Windows more convenient, quick.

Accompanying drawing 1 is the utility model scheme one layout;

Accompanying drawing 2 is the utility model scheme two layouts;

Accompanying drawing 3: be the utility model scheme one key bitmap;

Accompanying drawing 4: for the utility model scheme one alphabetical frequency just is provided with figure;

Accompanying drawing 5: be the utility model scheme two key bitmaps;

Accompanying drawing 6 just is provided with figure for the utility model scheme one alphabetical frequency;

The utility model is elaborated during below in conjunction with accompanying drawing.

We add up the frequency that 26 letters occur with program, the total degree of letter statistics is 67350753, according to frequency of occurrences ordering from high to low see the following form (wherein E (%) is the mean value of each alphabetical frequency of occurrences, and D (%) is the variance of each alphabetical frequency of occurrences).

E T A O I N S H R D L U CE(％) 12.6 9.1 7.9 7.6 7.0 6.9 6.4 6.2 5.9 4.2 4.0 2.8 2.7D(％) 0.1 0.1 0.0 0.0 0.1 0.0 0.1 0.4 0.0 0.1 0.1 0.0 0.2

M F W Y G P B V K X J Q ZE(％) 2.7 2.4 2.1 2.0 1.9 1.8 1.6 1 0.7 0.2 0.1 0.1 0.1D(％) 0.0 0.0 0.1 0.0 0.0 0.1 0.0 0.0 0.0 0.0 0.0 0.0 0.0

From table, can find out following 2 points:

1. single from frequency averaging value numerical value, the having levels property of mean value of each alphabetical frequency of occurrences can mark three separations 6.0%, 4.0% and 1.0%.8 letters (ETTAOINSH) of normal use have been marked respectively, 3 (RDL) of inferior normal use, common 10 (DCMFWGPBV) and minimum use 5 (KXJQZ) wherein the most normal use and the frequency of occurrences that time normal 11 letters that use are total up to 78.1%, the total frequency of occurrences of 5 letters of minimum use only reaches 1.2%, can find out thus, the frequent letter that uses has only 11, and has 5 letters not use substantially, has shown extremely inequality of alphabetical use.

2. can be found out by variance in addition that except that letter " H " and " C ", variance is all very little, only is 0.0 or 0.1, this explanation each letter in the quilt text of adding up occurs frequently single-phase when stablizing, and the mean value that draws in the table promptly can be used as the actual frequency of occurrences of each letter.

By last, we have drawn the frequency of occurrences of 26 letters, so, how by each alphabetical frequency of occurrences height each letter to be arranged into corresponding suitable key position has made into sixty-four dollar question, addressing this problem the most basic principle is exactly: 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 character area of 30 basic key positions, this comprises 26 letters and 4 characters, the character area of shape parallelogram (seeing accompanying drawing 3) is exactly the zone of our research, when the physilogical characteristics from the finger keystroke just can be arranged into corresponding key position with each letter by each alphabetical frequency of occurrences and form improved keypad character district layout by after impacting complexity row one order in 30 key positions for this reason.

And after this parallelogram zone is severed by its side directions from the centre, again left part is made just to have formed behind the flip horizontal the symmetrical figure (seeing accompanying drawing 4) that the parallelogram by two levels constitutes.This figure is exactly the character area of our the natural keyboard that will study.(what be called nature is because be 30 ° of angles approximately during people's both hands nature keystroke, and the layout of this keyboard just in time is fit to this characteristics).

There are following characteristics in finger when keystroke:

1 dirigibility, endurance are pressed forefinger, middle finger, and nameless, little finger of toe successively decreases successively, and existence one class difference between forefinger and middle finger, the third finger, have a class difference between middle finger, the third finger and the little finger of toe again.

2. ordinary people's right hand is flexible than left hand.

3. finger outwards stretches than inwardly withdrawal is easier.

4. forefinger is because of its dirigibility.Endurance than middle finger, the third finger and little finger of toe by force many, but its length is short slightly, so translation and to impact in it key position, skew back below easier than stretching.Need not drive wrist.

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

6. both hands alternate key stroke speed is the highest, and one hand changes and refers to take second place, and singlehanded finger together is minimum.

According to 6 above points, can draw the use difficulty or ease order of each key position of common and natural character area.Getting of two figure done an explanation at this point below: by These characteristics 4, so forefinger translation and impact that key position, skew back below all is easy to accomplish in it is can be with the base key position of the zone in accompanying drawing 3 and 41 as forefinger.Left and right district symmetry among Fig. 4 is so the base key position of forefinger also is symmetrical.And in Fig. 3, left index finger will impact its right side and tiltedly descend the square key position but more but to be difficult to accomplish because of its position, so reduce by a key position.8 key positions that finger initially places when the base key position of forefinger and keystroke and back together total base key position that formed.See the zone 2 in accompanying

drawing

3 and 5, the reason of doing this merging be because: the dirigibility of forefinger, endurance is high than other three finger, and forefinger moves and impacts its base key position base key position the same easy accomplish initial with finger stroke, and degree is low slightly only easily.

In addition by characteristics 5, the most difficult 4 the key positions that impact of can drawing, they lay respectively at 4 corner positions of character area.

Based on above total base key position and the key bit position that is difficult to impact most, can further determine the use complexity order of each key position of character area, see the numeral in accompanying

drawing

3 and 4, the more little then easy more use of numeral.

By numeral as can be seen: base key bit digital minimum, because of its easiest use; Four jiaos of key total word maximums, this is because it is difficult to use most; Right hand region key total word is all less than corresponding left hand district key total word, and this is because characteristics 2; In row numeral less than upper and lower row, on arrange numeral again less than row's numeral down, this is because characteristics 3; Two adjacent numerals place the left hand and right hand district respectively, and this is for characteristics 6; The numeral of middle key position is less than both sides, and this is for characteristics 1.

So far, we have drawn each key position of character area and have used the difficulty or ease order, but suitable key position still has a problem unresolved just being arranged into accordingly by the frequency of occurrences 26 letters, is exactly the arrangement of 4 characters.At this, following row's key position that 4 character unifications can be arranged in right hand region promptly character "; " change into being arranged at and arrange several second key positions, a left side under the right hand region, this is for following 3 points: one, be the transition with present keyboard layout; Two, with 4 character arrangements same row, can expect soon in the time will keying in these 4 characters when importing like this that they all are under the right hand row, thus the dispersion of notice when reducing input; Three, also be because the statistics of the alphabetical frequency of occurrences.We have drawn the most normal use and time normal 11 of the letters that use, arrange just to form these 11 letters like this and can be arranged in the base key position fully, that is to say that in the input of 100 times English alphabets, about need not point for 78 times moved or only needed slight the moving of forefinger just can finish.

Through to the statistical results show of a large amount of english articles, 26 letters each alphabetical frequency of occurrences under the bigger situation of total occurrence number is very stable and have apparent otherness, and the frequency of occurrences accounts for the letter of top ten and arranges as follows:

E T A O I N S H R D

12.6 9.1 7.9 7.6 7.0 6.9 6.4 6.2 5.9 4.2(％)

These ten total frequencies of occurrences of letter are about 75%, and promptly in the input english article, it is to impact this ten letters that 100 letters of keystroke have 75 times approximately.

The female frequency of occurrences of a composing is in the middle of the basic key-position area of original QWERT keyboard:

A S D F G H J K L ；

7.9 6.4 4.2 2.4 1.9 6.2 0.1 0.7 4.0 0.0

These ten total frequencies of occurrences of letter are about 35%, with ten letters of the most normal appearance always now frequency 75% compare and differ greatly.So keyboard letter key second row is made as successively: E, T, A, O, I, N, S, H, R, D.

So far, the alignment placement that can finally draw character area in conjunction with the setting of the use complexity of the frequency of occurrences of 26 letters and each key of character area and 4 characters is arranged (being the plain edition keyboard) by parallelogram, then letter first row is followed successively by: Q, Y, F, C, K, V, U, M, W, J key, second row is followed successively by: H, N, O, T, D, R, E, A, I, S key, and the third line is followed successively by: Z, B, P, G, X, L; Key.If by two symmetrical parallel quadrangular arraies (being the natural type keyboard) then letter key first row be followed successively by: Q, G, W, M, X, K, C, F, Y, J key, second capable being followed successively by: H, N, O, T, D, R, E, A, I, S key, the third line are followed successively by: Z, V, B, P, U, L; Key.

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 Wndows operating system of the later Microsoft of Windows95, only need to eject corresponding menu or option by a key.So far, existing two keys are done to be composed with the singly-bound shortcut, be respectively beginning (Start) key and application (Appllcatlan) key, 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 (minimizing current window) and ALT+F4 (closing the current active window), these three operating keys are arranged in the function key zone, title and figure name with Microsoft itself are labeled as " Explorer " respectively, "-", " X ".
