Description

A digital keyboard convenient for Chinese and English input

Technical field: computer input device - design scheme of keyboard

Background technology: although the English keyboard widely used in China can also realize the input of Chinese and English at present, it is not very convenient to use, because it has the following deficiencies: (1) only people who know 26 English letters can use this keyboard. Keyboard; (2) It is not very convenient for people who know 26 English letters to use, because the order of English letters is very disordered, not arranged in the order of the English alphabet, it will take a long time for beginners to be familiar with and master the keyboard. time; (3) after mastering the keyboard, it is only more convenient for inputting English and full spelling, it is not convenient for double spelling input, nor is it convenient for the input of font code and phonetic code, because there is no information mark of them on the keyboard , this is also the main reason why the Quanpin input method is currently popular, while other input methods are increasingly "declining" (that is, the keyboard is causing trouble); (4) most of the current input methods cannot be easily converted into numbers Input is not conducive to the digitization and automation of input methods, it is difficult to realize the input of numeric keypads, and it is not very convenient to realize the input of mobile phone keypads. In order to make up for the above deficiencies, we have invented a digital keyboard that is convenient for both English input and Chinese input, so that any input method can be easily input, and can be easily converted into the input of a numeric keypad and a mobile phone keypad.

Summary of the invention: The overall pattern of the existing English keyboard is not changed, but the order of the 26 letter keys is regularly adjusted, and marks that are conducive to font code and double-pin input are added to the letter keys. is marked digitally as follows:

1. Arrange the 26 English letter keys in the existing letter key area according to the order of the English alphabet. The first row is arranged from left to right A, B, C, D, E, F, G, H, I, J ten letter keys, nine letter keys of K, L, M, N, O, P, Q, R, S are arranged in the second row from left to right, and T, U, V, W, X, Y, Z are seven letter keys, and the mark of ü is added on the V key, so as to facilitate the beginners of Quanpin input method to use. (see picture 1)

2. Provide keyboard marks for Shuangpin. There are many and varied schemes for Shuangpin at present, but the amount of memory is not small, which seriously affects the popularization of Shuangpin. Based on years of research, we have provided a set of very regular Shuangpin solutions for the inventors and users of the Shuangpin input method in the future, so that they can learn from and use them conveniently. details as follows:

1, double initial consonant zh, ch, sh are marked on I, U, ü (V) key, i.e. zh=I, ch=U, sh=ü (V). See Figure 2

2, the first seven ai, ei, ui, ao, ou, iu, ie in the first nine general complex vowels in the pinyin alphabet are marked successively on the seven consonant keys of the first row from B to J ( Skip when meeting vowel letter key E and I), promptly B=ai, C=ei, D=ui, F=ao, G=ou, H=iu, J=ie. The eighth complex final vowel üe is owing to be very similar with the front part of ui, just let the two gather together, mark jointly on the D key, promptly üe=D=ui. Since the ninth compound final er is always zero initials, it will never match any initials, so there is absolutely no need to mark it on the keyboard for one-key input, and press e and r whenever you want to input er Two-key input is more in line with the characteristics of Shuangpin. If someone insists on marking, marking it on any consonant key will not produce repeated codes with other words. Therefore the first row of letter key also can be referred to as general complex vowel area, see Fig. 2.

3. Mark the 9 nasal finals in the pinyin alphabet on the 8 keys from K to S in the second row (skip when encountering the vowel key O), wherein un and ün share an N key, namely an =K, en=L, in=M, un=N=ün, ang=P, eng=Q, ing=R, ong=S, see Fig. 2. Therefore, the second row of letter keys can also be called the nasal vowel area

4. The remaining 11 compound finals are unsorted compound finals in the primary school pinyin alphabet. It is a little difficult to master, but there are rules to follow. First of all, we mark the compound finals ia and ua composed of two letters on the T key of the third row, and mark uo on the single final key o key (so that we will not make mistakes because we cannot distinguish the pronunciation of o and uo ); the compound final vowel uai, iao, ian, uan (containing üan) that three letters form is marked on 4 key positions from V to Y successively, wherein uan and üan share a Y key, namely V=uai, W =iao, X=ian, Y=uan=üan; the compound final vowel iang and uang of four letters will be marked on the Z key, and at last the iong is also marked on the S key, so that it and ong coexist in one key, which is easy to grasp , see Figure 2. Therefore the third row of letter key also can be referred to as combined final vowel area.

In this way, all double initials and complex finals are marked on the keyboard regularly, which is very conducive to the learning and mastering of Shuangpin, the popularization and improvement of Shuangpin, and thus the speed of the pinyin input method can be greatly improved.

3. Keyboard marks and invisible marks are provided for font codes and phonetic codes, making the input of font codes or phonetic codes more convenient. At present, the input method of font-code and phonetic-stroke code is multifarious especially, and scheme is extremely many, but learning difficulty is generally all larger, and the input speed that is easy to learn is very slow again. This has a lot to do with the plain English keyboard currently in use. Because there are no marks of strokes and parts (also called radicals) of any Chinese characters on the keyboard, the corresponding relationship between many strokes and parts and letter keys can only be mastered by rote memorization, so relatively speaking, the learning difficulty of font codes and phonetic codes Just bigger, make people " daunting ", would rather learn the pinyin input method that input speed is relatively slow but well mastered, also be unwilling to learn the font code or phonetic code input method that input speed is very fast but difficult to master. Is it possible to make simple marks on the keyboard, just can provide a broad basis for various font codes or phonetic-stroke code input methods? We think it's possible. Because any input method related to the font code is all input by parts or strokes. The components and strokes are regular. According to the "GB13000.1 Character Set Chinese Character Order (Stroke Order) Specification" promulgated by the state, all the strokes of Chinese characters are simply summarized into five types: horizontal, vertical, dot, and fold, which are represented by numbers as 1, 2, 3, 4, 5, i.e. 1=horizontal, 2=vertical, 3=left, 4=dot, 5=folding, where the pen is lifted to the horizontal, the pen to the down is to the point, except for the left vertical hook to be vertical, any other The strokes of the turning point are all attributed to folding. Accordingly, we can mark these five basic single strokes on the five keys from U to Y in order, as shown in Figure 3. However, it must be very slow to input Chinese characters completely by single stroke. Therefore someone has invented the method of double-stroke input Chinese character, promptly one key inputs two Chinese character strokes simultaneously, and this is a huge progress. Since there are only five basic single strokes, there are only 25 double strokes at most, as shown in Figure 4. Represented by numbers is the form of Figure 5. Since there are 26 English letter keys on the keyboard, it becomes possible to represent a kind of double stroke with one letter key, as shown in Fig. 6 . As can be seen from Fig. 6, we put five kinds of double strokes 11 (horizontal and horizontal), 12 (horizontal and vertical), 13 (horizontal skimming), 14 (horizontal dot), 15 (horizontal folding) in order that the first stroke is all 1 (horizontal) Arranged on the five key positions of A, B, C, D and E, therefore, these 5 letter keys can also be called 1 (horizontal) area; the first stroke is five kinds of double strokes of 2 (vertical) 21 (Vertical), 22 (Vertical), 23 (Vertical), 24 (Vertical point), 25 (Vertical folding) are arranged on the five keys of F, G, H, I, J in sequence, therefore, These 5 letter keys can also be referred to as 2 (vertical) districts; The first stroke is all five kinds of double strokes 31 (horizontal), 32 (vertical), 33 (left), 34 ( apostrophe), 35 (skimming) are arranged successively on five key positions of K, L, M, N, O, therefore, these 5 letter keys can also be called 3 (skimming) districts; Five kinds of double strokes 41 (dot horizontal), 42 (dot vertical), 43 (dot left), 44 (dot point), 45 (dot fold) of 4 (dot) are arranged in P, Q, R, S, On five key positions of T, therefore, these 5 letter keys also can be referred to as 4 (dot) districts; The first stroke is all five kinds of double strokes 51 (folding horizontally), 52 (folding vertically) of 5 (folding). , 53 (folding), 54 (folding point), and 55 (folding) are arranged on the five key positions of U, V, W, X, and Y in turn. Therefore, these 5 letter keys can also be called 5 ( fold) area. Like this, the corresponding relation of 25 kinds of double-strokes and 25 letter keys is just determined very regularly, promptly the first stroke of double-stroke determines which district it is on the keyboard, and the second stroke determines which district it is in. The key positions are clear at a glance and do not need to be memorized at all. For example, the digital code of the vertical double pen is 32, so it belongs to 2 digits of the 3 districts, and if you want to input the vertical double pen, press the key marked 32, that is, the K key; the digital code of the foldable double pen is 55, then Just belong to 5 digits of 5 districts, want to import this double pen and just press the key that is marked with 55, i.e. Y key; The bond, that is, the H bond. How to input other double strokes is self-explanatory. The only thing that needs to be explained is that there is still a Z key on the letter keys without any number marks. Considering that some font-code input methods may use the Z key, the Pinyin input method and English input must use the Z key. To realize digital input (see later), we have marked the number 6 on the Z key.

With the single-stroke and double-stroke markings on the keyboard, various input methods that are only related to strokes are very convenient. But, except stroke, also have a lot of font-code input methods to also adopt component input, according to " modern commonly used character component and component name specification " promulgated by the country, the component of standard is just as many as 512, so many components must be marked It is an unrealistic thing on the keyboard, and it is also of little significance, because even if it is really marked on it, it is not easy to remember and master. Is this keyboard powerless to the input of parts? No, definitely not powerless, but promising. Because any part is composed of a single or more than two strokes, if it is a single stroke part, it can be input through the single stroke mark key introduced above, if it is a part composed of more than two strokes, just hold This " bull nose " of this part " head double pen " (the first stroke and the second stroke) promptly grasps this key point of " head double stroke ", then inputs by the corresponding double stroke marking key. That is to say, for any parts composed of more than two strokes, which button this part belongs to is completely determined by its "head double pens". The corresponding double-stroke marking key input, that is, the first stroke of the "head double stroke" determines which area it is on the keyboard, and the second stroke determines which key position it is in this area, which is called the "head double stroke" of the component. Two pens determine the key button principle". For example, if the first double strokes of the "white" part are 丿丨, and the numerical code is 32, then it belongs to the button marked with 32; the first double strokes of the "horse" component are 乛乛, and the numerical code is 55, so it belongs to On the button that is marked with 55; Other components belong to which key and so on, which is self-explanatory. From this, we can also see that the parts assigned according to the principle of "the first two pens determine the button" are all "invisible parts". Although they are not directly marked on the keyboard, as long as the user has mastered the ", you can quickly know which button they belong to, and you can be truly "handy" and clear in your chest. This is called no parts in the key, but a part in the heart. In this way, all single strokes, double strokes and parts all have simple, clear and clear correspondences with the letter keys on the keyboard (also known as "graphic code number keys" now), thereby providing various forms of The code input method provides a good foundation and platform from strokes to components. Through this platform, no matter the inventor or the user of the font-code input method, they will no longer feel that the font-code input is a difficult thing. It is easy to learn and no longer memorize it by rote, which is very beneficial The popularization, popularization and improvement of font-code and phonetic-graphic-code input methods are conducive to promoting the Chinese character culture of the Chinese nation, so that the ancient Chinese character culture can also promote its own input characteristics in the computer field, and will never decline.

4. Make appropriate adjustments to a few invisible parts and mark them on the keyboard.

Completely follow the "principle of double pens on the first head to determine the button", without making any adjustments to the invisible parts, you can create a quite satisfactory graphic code input method, which can fully meet the needs of general typing. However, for some inventors and users who want to pursue extremely fast typing speed, it is not enough to fully follow the "principle of the first two pens to determine the button" because the components are input completely according to the "principle of the first two pens to determine the button". The distribution on the keyboard is not very even. There are more parts on some buttons, and there are fewer parts on some buttons. It is easy to generate repeated codes on buttons with more parts, and the usage rate of buttons with fewer parts is lower, which is not conducive to the improvement of the overall input speed. Therefore, if you want to pursue a faster typing speed, you should "kill the rich and help the poor", and transfer some components on the multi-component keys to the few-component keys, which is also called "frequency modulation". With reference to the word-building ability of the components counted in the "Modern Commonly Used Character Components and Component Name Specifications" promulgated by the state, and combined with our many years of coding practice, we boldly made preliminary frequency adjustments that we think are reasonable for some invisible components, so as to facilitate the pursuit of The inventor and user of the high-speed typing input method tried it out in order to obtain a more reasonable and scientific FM result in the future. If can be based on this, all font codes are all unified, accomplish the scientificization and standardization of font code input, also will be the thing of a meritorious deed. details as follows:

1. The wood parts on the 12 keys are transferred to the 52 keys, the Lv parts are transferred to the 14 keys, the push parts are transferred to the 15 keys, and the earth parts are transferred to the 55 keys.

2, the mountain part on the 25 key is transferred on the 21 key, the day part is transferred on the 22 key, the mouth part is transferred on the 23 key, and the worm part is transferred on the 24 key.

等)转移到42键上，非成字部件的代表键为玄字头亠；把31键上的钅部件转移到51键上；把44键上的氵部件转移到53部件上；把35键上的月部件转移到54键上。3, all non-character parts (亠, 疒, 冫, 丬,

etc.) are transferred on the 42 keys, and the representative key of the non-character parts is a black prefix; the 钅 parts on the 31 keys are transferred to the 51 keys; the 鰵 parts on the 44 keys are transferred to the 53 parts; the 35 keys are transferred The monthly parts on the 54 keys are transferred.

4. Considering that the moon part and the "冃" at the bottom of the blue character are difficult to distinguish, the bottom of the blue character on the 25 key and the month part are put together and share the 54 keys.

At this point, all FM is over. The parts after FM transfer are all marked on the key positions, and the parts without marks are still invisible parts according to the "principle of double pens on the first head to determine the button", as shown in Figure 7. In Figure 7, we can also find that the 5 parts transferred to the 5th area are arranged successively into gold (beside the gold word), wood, water (three points of water), moon (including 冃), and soil, which is very meaningful. Aids in memory. Therefore, all the FM results can be summed up in four catchy jingles:

Grass head handle 14-5, (grass head and handle are transferred to 14 and 15 keys respectively)

Point horizontal non-word to Q; (the non-form word parts of point horizontal double pen beginning are transferred to 42 keys and be on the Q key)

Yamichikou worms are arranged sequentially, (the 4 parts of Yamahikouchi worms are arranged on 21, 22, 23, 24 in turn)

Gold, wood, water, moon and soil are the last. (Zi wood and moon soil are arranged on keys 51, 52, 53, 54, and 55 in sequence)

After mastering these four jingles, add the single and double strokes of the previous marks and the invisible parts without marks, you can create a very fast input method of shape code or phonetic shape code, so that Chinese characters can be input in a computer. In terms of speed, it can gain a huge advantage, so that it can "stand out from the crowd" and "better than me". Of course, our FM is not necessarily the most perfect, and needs to be further explored, because the input method has never been the best, only better.

5. The magical effect of font code and digital code mark

From the above introduction, it can be seen that adding number marks on the basis of letter keys is the need of the font code input method. With the number marks, various font code input methods become very easy, and there is no need to remember Parts, back parts too. However, the function of digital marking is by no means limited to this, it also has the following three important functions:

1. It is convenient to directly convert various font-code input methods into numeric keypad or mobile phone keypad input. Method is when making original code table file, directly encodes (the numeral code of parts is determined by its head pair of pens) with the number code of stroke and parts, rather than encodes with letter code. If there is a ready-made alphabet code table file, the alphabet code table file can be converted into a digital code table file very quickly according to the corresponding relationship between letters and numbers on the keyboard map, using the replacement function of the document software.

2. It is very convenient to convert various pinyin input methods into numeric keypad or mobile phone keypad input. Because this keyboard is all marked with numerical code on each letter key, and this mark is very regular, thereby also be easy to learn and grasp. Its characteristics are: A, B, C, D, E correspond to 11, 12, 13, 14, 15; F, G, H, I, J correspond to 21, 22, 23, 24, 25; K, L, M, N, O correspond to 31, 32, 33, 34, 35; P, Q, R, S, T correspond to 41, 42, 43, 44, 45; U, V, W, X, Y, Z correspond At 1, 2, 3, 4, 5, 6. After mastering this feature, it is easy to realize the digital input of the pinyin input method. First of all, according to the above corresponding relationship, use the replacement function of the document software to convert the code table file of the pinyin letters into a digital code table file, and then install it on the computer or mobile phone to use it. Just the people who do not understand this keyboard at all, as long as they have mastered the corresponding relationship between the above letters and numbers, they can easily compile or use the software for digital input of pinyin. The input speed of digital software is faster than the current letter input method on the small keyboard of the mobile phone.

3. It is very convenient to convert the English input method to the input of the numeric keypad or the numeric keys of the mobile phone. The principle is the same as above, as long as you master the correspondence between the above letters and numbers, you can easily compile or use English digital input software. Equally, the input speed of digitization software will be faster than current letter input method on mobile phone keypad.
