Detailed Description
Example one
Referring to fig. 1-17, the present invention provides a technical solution:
based on the novel keyboard design of initial and final layout, the appearance of the novel keyboard provided by the scheme is as shown in the attached figure 1 of the specification, and initial and final characters and punctuation characters are arranged on keycaps of the keyboard 1, so that the keyboard 1 is convenient for Chinese input;
according to the scheme, the common QWERT keyboard layout in the market is changed, English characters on the surfaces of the keycaps on the traditional keyboard are replaced by initial consonant characters and punctuation characters, and the keyboard design is more convenient for Chinese input.
The letter layout on the keyboard on the market at present is directed at an English input method, a layout specially designed for Chinese input does not appear at present, the project abandons a single letter spelling mode of English input, an initial consonant-vowel input mode is designed according to a Chinese spelling habit and the characteristic that Chinese input is mainly word, a complex vowel character is added, special symbols of English input are removed, the weight of each initial consonant is calculated by an algorithm, and the Chinese keyboard layout is designed by combining human engineering.
After research and research, most character editing workers using double spelling for simplifying and accelerating typing speed are found, and the keyboard can accelerate the typing speed of double spelling and improve the Chinese input speed.
Meanwhile, near ten million characters of three types of data of news, blogs and novels are captured, the number of each initial consonant and the final is counted, the correlation degree of the initial consonant and the final is judged by utilizing a correlation matrix, the arrangement sequence of the initial consonants and the final is analyzed according to human engineering documents, and the arrangement diagram of the initial consonants and the final is manufactured.
First, the questionnaire is analyzed for a specific user and a market, i.e., a group of people who need to use a large amount of chinese for typing (news editors, chinese novels authors) and the like, and the displayed results of the questionnaire are shown in fig. 3 to 5 of the specification. The questionnaire shows that 78.85% of users in the specific user oriented input, the existing keyboard with English layout has low efficiency for inputting Chinese characters, people are generally familiar with the layout of English keyboard but can not improve the efficiency better, and for this group we have carried out the second questionnaire issue to explore whether they are willing to accept the layout of Chinese keyboard, wherein 63.83% of users think that they are willing to accept the layout of Chinese keyboard as long as the efficiency of code word can be improved, wherein most of the word editors use double spelling, and we draw conclusions from the questionnaire: the project has good market prospect.
Then we continue to collect datasets (related works, scripts, etc.) for specific target users, crawl text data using the beautifuloup module, and crawl according to order or keyword information. By specifying the number of pages traversed, the contents of the specified website can be crawled and written locally.
Part of the code is shown in figure 6 in the specification.
And then cleaning the obtained data set, screening out data which do not meet requirements, such as messy codes, wrongly written characters, English input and the like, and performing corresponding transcoding on the data which meet the conditions by utilizing the pronunciation rule of a python reading pinyin dictionary to obtain the required initial consonants and vowels, wherein part of codes of the initial consonants and vowels are shown in the attached figures 7-8 of the following description.
The results are shown in FIGS. 9-10 of the specification.
Then, we consult the related literature (article number of the' English input keyboard layout modification): 1000-7024(2004)01-015304-04) and record that "the letter zone is left-right symmetrical so that only one side needs to be studied, the other side can correspondingly deduce 4 types of conditions that the right side is selected according to the movement of fingers and palms when clicking, the letter zone of the natural keyboard can be divided into some basic zones firstly, and 4 RMZs, RM3, RM4 and RMS, namely the keys initially placed by the fingers of the right hand when clicking are obtained for the 1 type of conditions (see the middle row light gray zone on the right side of FIG. 4 in FIG. 11 in the description); for the 2 nd case combined with the characteristics 35, it can be concluded that one key position RDZ of index finger retraction stroke and two key positions RU3 and RU4 of middle finger and ring finger extension stroke total 3 key positions, so that it can be concluded that the extended basic key position region is composed of 7 extended basic key positions (see the whole light gray area on the right side of figure 4 in figure 11 of the specification) including 4 basic key positions; for the 4 th case, the corresponding key position area which is most difficult to use can be obtained (see the upper left corner dark gray key position on the right side of the figure 3 in the attached figure 11 of the specification); finally, the general key position area corresponding to the 3 RD type condition, i.e. the area composed of the other 5 key positions RUZRMIRDIRD3 and RD4 except the expanded basic key position area and the most difficult key position area, is obtained, for the letter area of the general keyboard, because the left side of the letter area does not conform to the natural angle of the left hand when the user clicks, the left side of the letter area is not in bilateral symmetry, so that the adjustment is needed to be made according to the using difficulty and the ease sequence of the key positions of the natural keyboard, for example, for the expanded basic key position area on the left side of the letter area, because the left hand and the index finger retract to hit and the key position which does not pull the wrist does not exist, one expanded basic key position is reduced (see all light gray areas on the left side of figure 6 in figure 11 in the description), for the numbers of the expanded basic key position area of the natural keyboard, the order of the index finger and the little finger responsible for hitting is increased sequentially, which is because the key positions of the non-basic key position area of the characteristic 4 are all larger than the corresponding key positions (correspondingly, respectively, the same finger is responsible for hitting otherwise), is because the condition 2 It should be noted that the most important key position number for the little finger to hit is because the difficulty level of using the key position in the most difficult key position area and the normal key position area corresponding to the feature 6 can be similar to the last, and the difficulty level of using the key position on the left side of the natural keyboard can be obtained according to the features 1 and 2, which can be referred to all the numbers in the figure 11 of the description and figure 6 of the figure 4 of the figure size of the general keyboard letter area on the left side of the figure 11 of the description.
Based on the difficulty degree of using each key in the key area in the document, the initial consonant obtained after the analysis is placed in an easy place in the key position, and most of the final consonants only need to be complemented by pressing tab keys based on the word input of the project.
In the key position design arrangement, the load born by the flexibility degree of each finger in human engineering is also considered, the reference document is 'exploration about the keyboard letter layout of the Chinese phonetic input method' chapter number: 1003-; according to engineering psychology experimental data, the interval of the motion of knocking the keyboard by the same finger is 0.09s on average, the interval of the knocking motion between different fingers of the same hand is 0.03s on average, the interval of the knocking motion between the fingers of different hands is 0.02s on average, the efficiency of alternatively knocking the keyboard by the left hand and the right hand is higher than the efficiency of continuously knocking the keyboard by a single hand, and the fingers are less fatigued under the condition, so that the knocking motion is performed alternately in the left hand and the right hand as much as possible, and the recorded data are shown in the attached figure 12 of the specification.
Secondly, when considering common initial consonant statistics, in order to discharge more initial consonants of Chinese characters to a more suitable position, the value of the alternation rate is required to be as close to 1 as possible, and the reference is 'exploration about the keyboard letter layout of the Chinese pinyin input method' chapter number: 1003-0077(2010)06-0108-06 ', wherein the description is that' a left key region is an A region, a right key region is a B region, and the pinyin of a Chinese character is a1a2 … ai … an, wherein ai ∈ { a, B, c, …, z }, the pinyin length a1a2 … ai … an <7, i ═ 1, 2, …, N, N ∈ N +, if ai appears in the A region and ai +1 appears in the B region, a certain character is called that the left hand and the right hand are alternated, and the ratio of the number p of Chinese characters which are alternated by the left hand and the right hand to the total number q of Chinese characters is called as the alternation rate. Here, we use the alternation rate for reference, and consider that the initial combination under the condition of left-hand and right-hand matching can drive more words, i.e. more Chinese characters, so that the value of the alternation rate approaches to 1 as much as possible, and we analyze a large number of data sets through python, and part of codes of the data sets are shown in the attached figure 13 of the specification.
And (5) counting the correlation of the parents of all the two-word words, and constructing a correlation matrix. And the keyboard layout is preliminarily designed according to the statistical result, the display result is shown in the attached figures 14-15 of the specification, and the darker areas in the figures are the combinations of the initial consonants, so that more words can appear in the combinations of the initial consonants, and the initial consonants can be placed in more reasonable places.
Continuing, we have further studied human engineering, and the reference is 'exploration on the keyboard letter layout of the Chinese pinyin input method' chapter number: 1003-. "it is reasonable to have a left keypad larger than a right keypad in the workload, but not much more than necessary, as shown by the graph data; it is reasonable in workload that the middle row > the upper row > the lower row. We also use this as one of the important factors of the layout in the keyboard layout.
Therefore, the arrangement of the initial consonant and vowel characters in the attached figure 1 of the specification is designed at present.
In conclusion, the design idea of the scheme is as follows:
firstly, determining a specific user group, collecting corpus data on regular websites such as a national statistical network and CNKI (CNKI), taking the corpus data as a data set for empirical statistical analysis, respectively counting word frequencies of two-word words and multi-word words through technical means such as data cleaning and word segmentation, constructing a dictionary from Chinese characters to pinyin, and mapping the Chinese characters to the pinyin;
analyzing the correlation between the initials and the finals in the vocabulary by utilizing the principle of statistics, and determining the importance of the corresponding key positions according to the strength and the occurrence frequency of the dependency relationship;
thirdly, the keyboard layout based on the initial consonant and the vowel key positions, which has higher alternation rate, can enable the fingers to be less fatigued by comprehensively designing a theory by combining the difficulty degree of using each key position in the traditional keyboard layout, the flexibility degree of each finger in human engineering and the corresponding load capacity;
fourthly, analysis algorithm: text data are collected for a class of people needing layout design and are mapped to corresponding pinyin sequences and consonant and vowel sequences. And then converting the pinyin sequence into a directed weight graph by using a TextRank algorithm. The important components in the text are sorted by using a voting mechanism, and the key words can be sorted only by using the information of the current document. The required key words are not extracted finally, but undirected weighted graphs learned by the model in the iterative training process are extracted and used as references of keyboard layout;
and fifthly, in concrete implementation, word segmentation and part-of-speech tagging are carried out on each original text data, stop words are filtered, transition to a pinyin sequence is completed, and sequencing based on correlation degree between initial consonants and vowels in pinyin is completed. The input of the sequence further refines the analysis of the original sentence level of the TextRank, and considers the co-occurrence degree of the initials and the finals by taking the combination of n continuous initials and finals in the pinyin sequence as metadata. Firstly, inputting a pinyin sequence which is mapped as a model, carrying out sequence annotation, and constructing an undirected graph G (V, E) related to initials and finals, wherein V is a node set and consists of all initials and finals, and E is an edge set and represents the correlation degree between connected nodes. And then, iteratively calculating an edge between two points by adopting a co-occurrence relationship (co-occurrence), wherein a relation necessarily exists between any two nodes, and the strength of the relation between the nodes is learned by inputting a pinyin sequence through the model. The setting of the collinear window size K is to be evaluated experimentally as a hyper-parameter. And (4) iteratively propagating the weight of each node and the weight of each edge according to a formula. On the other hand, the relevance calculation at the sentence level is separated, and the relevance of different initial consonants is directly calculated on the global context;
and sixthly, in implementation, the vocabulary sequence is obtained through data cleaning and word segmentation operation. And then extracting the front initial consonant and the rear initial consonant contained in the words, calculating the occurrence frequency of each different ordered binary group, drawing a correlation matrix according to statistics, and visually analyzing the correlation between the initial consonants.
And seventhly, a basic use rule of the input method is that after the correlation between the initials and the finals is calculated, according to a balance principle of left-hand and right-hand alternation rates in human engineering, a user hopes that the initials are input by the left hand of the user and then the finals are input by the right hand, or the finals are input by the left hand of the user after the initials are input by the right hand, according to the balance principle of left-hand and right-hand workload, the left-hand and right-hand workload is reasonably arranged in a designed way, so that the left-hand and right-hand workload is approximately the same, and the fingers are reasonably distributed according to the working intensity. Meanwhile, reasonable distribution is carried out on the layout according to the working strength of each finger.
Eighthly, letter key position arrangement design idea: the input of the Chinese character is divided into an initial consonant and a final sound, and the key positions are correspondingly changed into the initial consonant and the final sound. The whole initial consonant is positioned at the upper part of the keyboard. The consonants are directly input, and the vowels are input in a mode of complementing by using a complementing key.
Based on the layout design idea, the keyboard layout design mode is compared with a full spelling mode and a double spelling mode:
1. contrast double spelling
The specific vowel position mapping in the double spelling does not need to be memorized, and the vowel position mapping is visually represented by different key positions in the keyboard layout;
2. contrast full spelling
The designed keyboard based on the initial and final layout is superior to full spelling in the aspects of code length error rate (the code length is the number of times of pressing keys required for inputting a character, for example, the zhang full spelling code length is 5, while the novel keyboard only needs zh and ang, the code length is 2), fatigue and left-right hand alternation rate. Through logic analysis, the main reason for the difference is considered to be that the average code length is greatly reduced, the same content is input, the number of times of key pressing of the full spelling is more than that of the mode based on the initial consonants and vowels, the full spelling is slower to a certain extent on the premise of certain key pressing speed, the number of times of input of the full spelling is more, and therefore the possibility that errors need to be modified is higher.
