The present invention has raised double spelling typewriting efficiency and comfortable use feeling.
Based on the existing Qwerty keyboard, the initial consonants and the vowels are mapped to 26 letter key positions. In order to realize the design, the invention selects the following objective functions:
the working balance of each finger: scientific research and life common knowledge indicate that the strength and flexibility of fingers are from strong to weak: index finger, middle finger, ring finger, little finger. The workload distribution should therefore be:

Utilization rate of the main row key: a key area in the keyboard is divided into four rows, the rows from top to bottom are a, b, c and d respectively, and a main row key is defined as a row c. The utilization rate is as follows:
Figure BDA0001481686740000033
wherein eta isUtilization factor, NcThe number of strokes on the primary row of keys, N represents the total number of keystrokes.
Row key toggle frequency: define the letter of the ith input as ciDefining the letter input at the i +1 th time as ci+1And two inputs satisfy
ci∈Hp,ci+1∈Hq,p,q∈[1,2,3]
Wherein c isiIs the ith letter input, ci+1Is the letter of the i +1 th input, HpDenotes line p, HqRepresenting line q. Now introduce the 0-1 variable xiDefinition of

Now introduce the variable y of 0-1iDefining:

the row key toggle frequency is:
Figure BDA0001481686740000046
wherein A isiIndicating the area where the standard fingering is located and N indicates the total number of keystrokes.
And (3) establishing a constraint condition:
the left and right hand workloads are specified to satisfy the following relationship:
0.85WR≤WL≤1.05WR
wherein WRRepresents the right-hand workload, WLRepresenting the right hand workload.
For the 0-1 variables, there is a constraint that their cumulative sum must not exceed the total number of keystrokes, namely:
Figure BDA0001481686740000051
according to the common sense, zh, ch, sh are expressed by 3 of 6 vowels which are only used as vowels, and a, o, e can be independently formed into tones, so that to avoid the misjudgment of the initial consonants, zh, ch, sh need to be mapped into i, u, v, namely:
Figure BDA0001481686740000052
wherein Λ { ξ } represents a complex initial consonantSet of (2), ΩmRepresenting each letter-key set, Ψ, of the first rowmShowing the third row of each letter key set.
If all vowels except 6 vowels need to be represented by keys except 6 vowels, there are:
Figure BDA0001481686740000053
wherein, Λ { ζ } represents complex vowel set, E represents all letter key set, and ΓmRepresenting a second row of each set of letter keys. In order to enable people to memorize a double spelling scheme more quickly during double spelling input and to enable key distribution to be as uniform as possible, the coincident code rate of Chinese character key positions should be reduced as much as possible, namely, the condition that one key position replaces more than two initial consonants and vowels at the same time cannot occur, namely:
Num(Em)≤3,m＝1,2,L 26
wherein N isum(Em) Representation set EmThe number of elements of (c).
Selecting text data: selecting a Bingcheng (author: Shenyu, Beiyue literature and Art Press 2014 edition) as a data text, converting the data text into a Pinyin text, wherein the data volume is more than 15 ten thousand characters which can be considered to be large enough to represent the daily Chinese text input condition.
And (3) solving:
the first step is as follows: by utilizing a layering method, the maximum utilization rate of the main row key is the first level, and by combining the constraint conditions, the method comprises the following steps:
Figure BDA0001481686740000061
in summary, the first 16 complex vowels with the largest number of times of typing in the text data are mapped to Γm12, L19 is provided for 8 key positions, and the 16 complex vowels belong to the set together:
Λ{δ}＝{ao,en,ai,ang,ui,ian,ou,uo,an,ing,uan,ei,ong,eng,iao,in}
the second step is that: using greedyAnd (4) performing local optimal selection by using an algorithm. To determine the approximate target in the algorithm, 0.85W is used as the constraintR≤WL≤1.05WRCan be processed as WL≈0.9WRThen, for 26 letter keys, there are:
NΛ{δ}+NΛ{ζ}＝1.9NR
wherein N isΛ{ζ}Number of keystrokes for a single initial, NΛ{δ}The number of keystrokes for the 16 compound vowels, NRThe number of keystrokes for the right hand. From which an approximation target N is calculatedR-NL6790 times.
Then, a greedy strategy is customized, when the first eight compound vowels with the largest typing times are in the right hand region and the other eight compound vowels are in the left hand region, N is obtained through calculationR-NL＝5739<6790 times, so there is no optimal solution, i.e. the strategy should be as close to the target as possible, resulting in the situation of primary row key mapping as shown in fig. 1.
The third step: and (3) performing an optimal mapping scheme of other three complex initials and eleven complex finals by using a genetic algorithm based on the target, as shown in fig. 2.
Based on the Chinese double-spelling mapping scheme, the working balance f of each finger is obtained1Primary row key utilization factor f2The method comprises the following steps of switching the values of targets such as a frequency alpha, a two-hand alternating frequency beta, a finger alternating frequency gamma and the like back and forth by a row key, judging whether the target values meet the balance degree standard of left and right hand operation, calculating all index values of a known dog searching double-spelling scheme, and comparing the index values with the index values, wherein the specific steps are as follows:
f1 f2 α β γ satisfy the balance of the left and right hands
The design 2 45.17％ 67.93％ 54.94％ 84.96％ Is that
Dog-searching double spelling 2 34.99％ 64.84％ 49.93％ 84.14％ Whether or not
Longitudinal analysis is carried out, and for the mapping scheme, the matching deviation of the workload of each finger and the flexibility of the mapping scheme is 2, so the performance of the work balance degree is more ideal; the utilization rate of the main row key is basically close to 50 percent, and is considerable; the back-and-forth switching frequency of the health care is higher, and the alternating frequency of the two hands is lower, which can increase the operation fatigue of the hands, which is a place to be improved by the scheme; the finger alternating frequency is high, and the requirement is met; moreover, the left-right manual load distribution is also within a reasonable range and can be accepted. In summary, from the overall view, the double-spelling and vowel mapping scheme solved by the invention is considered to be effective in a reasonable and parallel manner.
The transverse comparison analysis is carried out, it is obvious that the Chinese double-spelling mapping scheme formulated by the invention has the same performance with the working balance degree of each finger of the dog searching double-spelling, the utilization rate of the main line key is far higher than that of the latter, the back-and-forth switching frequency of the line key is slightly lower than that of the latter, the alternating frequency of the two hands and the alternating frequency of the finger are both higher than that of the latter, the former meets the requirement of the balance degree of the left-and-right manual work, and the dog searching double-spelling scheme does not meet the requirement. In conclusion, the Chinese double-spelling scheme designed by the invention is superior to the dog searching double-spelling scheme in the index performance.
