Description
Technical field
The present invention relates to a kind of input method of Chinese character, relate in particular to a kind of sound subregion Chinese character pinyin input method, be particularly useful for the Chinese character input of touch-screen mobile phone.
Background technology
Chinese character input at present mainly contains search dog input method, Intelligent ABC input method, double-spelling Chinese character input method, Baidu's input method, king's code five-stroke input method etc.According to other alphabetic writings, can not possess, the notable feature that the Chinese phonetic alphabet is unique, the phonetic of each Chinese character is comprised of an initial consonant at most, (minimum for not having, as " and---er, like---ai " etc.), if in input, initial consonant (English consonant) and simple or compound vowel of a Chinese syllable (English vowel) are in the mixing of same region, obviously be quite irrational, present full keyboard layout, training method when having got used to inventing the earliest " typewriter " due to user completely, thereby on " microcomputer " keyboard, can " recite " use " touch system " of property and then improve typing speed, but, on mobile phone touch screen (particularly full keyboard pattern), realize touch system, almost impossible.So, after an initial consonant of input, when input simple or compound vowel of a Chinese syllable, simple or compound vowel of a Chinese syllable surrounds initial consonant around, just certainly will cause wrong by, and there is the inconvenience that " Two bors d's oeuveres association " needs " backspace " key to modify in aobvious hurdle in advance, and often the Chinese phonetic alphabet is not comprised of a single simple or compound vowel of a Chinese syllable, but the simple or compound vowel of a Chinese syllable combination that the letter such as similar " ao " or " ang " forms, because the single key of full keyboard on mobile phone touch screen is very little, the 4 inch screens of take are example, are only high 7mm, the rectangular area of wide 5mm, while there is like this input simple or compound vowel of a Chinese syllable, the probability that mistake is pressed initial consonant is just quite high.And this mode has been destroyed the formed traditional unique musical note aesthetic feeling of Bopomofo pronunciation feature.
English full keyboard bond order has caused a defect of having been ignored by people, because will adapt to and " typewriter " identical bond order, thereby causes the people with computation custom, can remove to find with " memory " help " vision " ad-hoc location of a key.This custom is rooted in the hearts of the people, but, because English full keyboard letter sequence only has three row, as shown in Figure 8, square letter key can only be arranged out the key mapping region of " prolate ", and mobile phone screen to be input method letter stay is the restricted area of approximate " square ", as shown in Figure 9.So, under English sequence full keyboard form, letter only has 3 row, but there are whole 10 row, so just certainly will cause 10 horizontal " row " will be arranged in a size that is wider than slightly 3 " OK " longitudinally, so, each key will be " vertically to " rectangle as Fig. 9, and wrong by probability in order to reduce as far as possible, every row letter key is mutually straggly with center line, is one typical " west " custom like this.
In input " Two bors d's oeuveres " pattern, no matter be English " nine keys " keyboard layout, still " full key board " keyboard layout, all need finger just can complete Two bors d's oeuveres input through certain " stroke ", the custom of each ten finger that have a fixed position on computor-keyboard is unchallenged for this " stroke ", but, for only having mobile phone touch screen of one or two finger input, with regard to relative difficult with easily made mistakes.
If take merely the concept of " the initial and the final is separated " layout, but, all simple or compound vowel of a Chinese syllable combinations are all enumerated on keyboard, there will be two defects: first, cause key mapping to surpass 26 keys of English layout, limited because of the area of single key, on a key, arrangement is as the simple or compound vowel of a Chinese syllable combination of " elongated " golygram combinations such as " iang ", just need in the middle of minimum letter, retrieve with eyes, this process is extremely to waste spirit.The second, keyboard layout be difficult to form the sequence of " logicality ", causes all information retrievals by vision, to pass to consciousness completely, or the memory of augmented form completes, and is unfavorable for like this user of preliminary contact.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of sound subregion Chinese character pinyin input method is provided, solved the problem of the inapplicable mobile phone of input method of Chinese character in prior art.
Technical scheme of the present invention is as follows:
Touch screen keyboard comprises initial consonant region, compound vowel region, function key region; Described initial consonant region ordering mode is by B, P, and M, F---D, T, N, L---G, K, H---J, Q, X---R, W, Y, Z, C, S lines up the five-element's four row; Simple or compound vowel of a Chinese syllable ü is positioned at after initial consonant X, attached h after initial consonant Z, C, S; Described compound vowel region be take i as core, and i is in centre, and a, e, o, u lay respectively at the form of formation nine grids up and down of i, simple or compound vowel of a Chinese syllable i and initial consonant G, and K, H key mapping is in same a line; Described function key region comprises funny number key, fullstop key, digital switch key, Sino-British handoff functionality key, decollator number key, mark function key, backspace key, space bar and enter key; When described keyboard switches to numeral by digital switch key, numerical key 123; 456,789 is corresponding to initial consonant g, k, h respectively; J, q, x; R, w, y are upper, and 0 key correspondence is on simple or compound vowel of a Chinese syllable ü.
The smooth vertical and horizontal typesetting of described keyboard, forms vertical laterally than the vertical rectangle that is 5:4; The initial and the final subregion, each letter key is square.
Described h keyboard is long-pending to be presented with 2/3 key mapping area of consonant key.
Described funny number key, Sino-British handoff functionality key and enter key and initial consonant B, P, M, F key colleague, after being sequentially arranged in consonant key.
The left and right sides of the final key a that described fullstop key and space bar are positioned at same a line.
Described mark function key mapping is in the rear of simple or compound vowel of a Chinese syllable u; Described mark function keyboard is long-pending to be presented with 2/3 key mapping area of consonant key.
Described numerical key and enter key are positioned at the left and right sides of the final key e of same a line.
Described segmentation symbol key mapping is between the consonant key L and final key ü of same row.
When described keyboard switches to numeral by digital switch key, on keyboard, comprise unit, computing formula and punctuation mark.
Advantageous effect of the present invention is as follows:
1, change the initial and the final lexicographic ordering that lexicographic order is Chinese textbook of elementary school, and make two regions with the initial and the final.Thereby increase the area of each letter key, reduce the wrong probability of pressing.
2,, by simple or compound vowel of a Chinese syllable assembled classification, utilize the conventional simple or compound vowel of a Chinese syllable combination of touch screen animation mode display section, as the simple or compound vowel of a Chinese syllable combination with initial consonant " n ", " ng " such as " an, ang ".Cause a characteristic regulations in function, while being a Chinese character of every input, finger contact initial consonant region only once, this is also the pronunciation character that has utilized Chinese character initial consonant unique, no matter how simple or compound vowel of a Chinese syllable district letter combines, and finger never returns to initial consonant district and operates, thereby reduces wrong probability, and help user brains and eye information interaction in input process, the pronunciation law of the strengthening Chinese phonetic alphabet one sound one rhythm.
3, suitably adjust function key area, as the layout of numeric keypad, reduce the utilization rate of symbol switch key; Suitably adjust function key as size and the color of " carriage return ", " space ", " backspace " key, thereby facilitate user to remember key mapping in the long-term process of using, and reduce the wrong probability of pressing.

Embodiment
Embodiment
As shown in Figure 1, first, touch screen keyboard is divided into three large functional areas substantially.
(1) initial consonant region
The phonetic " pithy formula " that in Chinese textbook of elementary school, teaching is used is used in initial consonant region, is sortord, changes original full keyboard
English sequence mode, that is: " B, P, M, F---D, T, N, L---G, K, H---J, Q, X---R, W, Y,---Z, C, S ".The adjustment that wherein has two places to make for being applicable to keyboard layout: first, owing to there being the children's folk rhymes formula pithy formula of " J; Q; the X urchin; see flake and just cut out " to go deep into the Chinese popular feeling in former pithy formula, so, simple or compound vowel of a Chinese syllable " ü " layout is entered to this initial consonant sequence, and the simple or compound vowel of a Chinese syllable district of (all the other five simple or compound vowel of a Chinese syllable) layout is close in position, these five simple or compound vowel of a Chinese syllable are also in English, to have and only five vowels i.e. " A, E, I, O, U ".Second, owing to there being and only having three initial consonants to combine with initial consonant in the Chinese phonetic alphabet, three letters " Z, C, S " of distinguishing " the flat tongue that sticks up " are corresponding to " Zh, Ch, Sh ", for fear of the inconvenience that appears at initial consonant district and click twice of screen in operation input, adopted two kinds of modes that these three initial consonants are emphasized out: 1, in layout, to utilize last three key mappings of the last column in initial consonant district to place this three letters; 2, with repeatability, " h " key that will represent a small letter of " sticking up tongue " presents with " 2/3 " individual key mapping area, when user needs input " sticking up tongue " initial sounds, without clicking this letter i.e. " Z, C, S ", only after need click corresponding letters, attached " h " can be in " aobvious hurdle in advance " inner presenting " cacuminal ", as clicked " S " " h " below, there is " Sh " in aobvious hurdle in screen in advance.
The advantage that the layout adjustment of initial consonant district brings is as follows:
1, one word is once: according to other alphabetic writings, can not possess, the notable feature that the Chinese phonetic alphabet is unique, the phonetic of each Chinese character is comprised of an initial consonant at most, (minimum for not having, as " and---er, like---ai " etc.), if in input, initial consonant (English consonant) and simple or compound vowel of a Chinese syllable (English vowel) are in the mixing of same region, obviously be quite irrational, present full keyboard layout, training method when having got used to inventing the earliest " typewriter " due to user completely, thereby on " microcomputer " keyboard, can " recite " use " touch system " of property and then improve typing speed, but, on mobile phone touch screen (particularly full keyboard pattern), realize touch system, almost impossible.So, after an initial consonant of input, when input simple or compound vowel of a Chinese syllable, simple or compound vowel of a Chinese syllable surrounds initial consonant around, just certainly will cause wrong by, and there is the inconvenience that " Two bors d's oeuveres association " needs " backspace " key to modify in aobvious hurdle in advance, and often the Chinese phonetic alphabet is not comprised of a single simple or compound vowel of a Chinese syllable, but the simple or compound vowel of a Chinese syllable combination that the letter such as similar " ao " or " ang " forms, because the single key of full keyboard on mobile phone touch screen is very little, (the 4 inch screens of take are example, are only high 7mm, the rectangular area of wide 5mm, while there is like this input simple or compound vowel of a Chinese syllable, the probability that mistake is pressed initial consonant is just quite high.And, this mode has been destroyed the formed traditional unique musical note aesthetic feeling of Bopomofo pronunciation feature, and after initial consonant region is rearranged by everyone initial " pithy formula " order of acquiring at primary school time, a Chinese character of each input, finger at most only needs in initial consonant district to click once, the wrong probability while so just greatly reducing simple or compound vowel of a Chinese syllable input.
2, reasonable and spacious layout: English full keyboard bond order has caused a defect of having been ignored by people, because adapt to and " typewriter " identical bond order, thereby cause the people with computation custom, can remove to find with " memory " help " vision " ad-hoc location of a key.This custom is rooted in the hearts of the people, but, because English full keyboard letter sequence only has three row, as shown in Figure 8, square letter key can only be arranged out the key mapping region of " prolate ", and mobile phone screen to be input method letter stay is the restricted area of approximate " square ", as shown in Figure 9.So, under English sequence full keyboard form, letter only has 3 row, but there are whole 10 row, so just certainly will cause 10 horizontal " row " will be arranged in a size that is wider than slightly 3 " OK " longitudinally, so, each key will be " vertically to " rectangle as Fig. 9, and wrong by probability in order to reduce as far as possible, every row letter key is mutually straggly with center line, is one typical " west " custom like this.Chinese visual custom is the typesetting of " smooth vertical and horizontal " " Chinese characters " shape, use the typesetting of the initial and the final subregion method, each letter key is " square ", whole initial consonant district is close to one " 4 row; 5 row " that square area is complete arranges, the similar Chinese character of shape vertical laterally than the vertical rectangle (as shown in Figure 1) that is 5:4.So, the area of each key (take 4 inch screens be 6.5mmX6.5mm for example) is increased.The every keyboard of the present invention is amassed as 6.5x6.5=42.25mm2, the every keyboard of English full keyboard is amassed as 7x5=35mm2, obviously, each key has increased 42.25-35=7.25mm2, although under the restriction of full layout area, the area change of every key is limited, but laterally only has 5mm due to former full keyboard, cause and click wrong probability, nearly all to push the wrong " in row " to be listed as adjacent letter, can't " inter-bank pushes the wrong ", horizontal every key (adding space) is similar to broadening 2mm now, so, the probability pushing the wrong on row and column equates, and, significantly reduced wrong by probability.
3, super " Two bors d's oeuveres " easily input: in input " Two bors d's oeuveres " pattern, no matter be English " nine keys " keyboard layout, still " full key board " keyboard layout, all need finger just can complete Two bors d's oeuveres input through certain " stroke ", the custom of each ten finger that have a fixed position on computor-keyboard is unchallenged for this " stroke ", but, for only having mobile phone touch screen of one or two finger input, with regard to relative difficult with easily made mistakes.Such as input " disconsolate ", the finger stroke of full keyboard, as the contrast of Figure 10 and Figure 11, in Figure 11, only need to can complete input by the small letter " h " after twice striking of same position " C ".Another example " advocating ", as the contrast of Figure 12 and Figure 13, can illustrate the simplification of finger shift motion more.Milli glitch-free the completing (needn't be subject to the interference of simple or compound vowel of a Chinese syllable letter completely) in a unified region that be operated in of initial consonant input, just more simple.Under the mode of Two bors d's oeuveres association input, if common user's defeated initial consonant and do not input the condition that simple or compound vowel of a Chinese syllable will face " super more options " completely only, such as input " address ", if only input the i.e. " d of initial consonant, z " there will be more than 30 word of page turning on screen, for user, select, in this case, user is usually by intactly inputting second word in the middle of a word, so both exempted from but to select the trouble of phonetically similar word, also exempted from but the trouble of a lot of letters of input, such as above said " advocating ", requiredly in the middle of Ben keyboard layout press " h " key after key mapping " C " once, " h " key after " S " once, then pin " a " key in simple or compound vowel of a Chinese syllable district, right sliding screen occurs that " ang " completes the accurate input of whole word.
(2) compound vowel region
The arrangement of compound vowel region as shown in Figure 1, is one and take " i " that (the highest letter of the frequency of occurrences in the middle of simple or compound vowel of a Chinese syllable combination) is core, in centre, and the form of " nine grids " in the only one China traditional culture of formation." nine grids " are that the Tang Dynasty calligraphist Ouyang Xun is incorporated into " calligraphy " imitation field the earliest, also be the earliest form of China " river figure ", what wherein numeral " 5 " was listed as at three row three is middle, so this pattern has formed " fixing " aesthetic feeling of being rooted in the hearts of the people in Chinese culture, if each lattice of finger (take right hand thumb as example) striking successively " nine grids ", its " running " mode, also can, from simple " grid " translation mode, become the mode of a kind of " circumference " motion.So, " i " that the most often use in Chinese phonetic alphabet simple or compound vowel of a Chinese syllable combination (as iu, ia, ie, io, ian, iang, the combinations such as iong, all with alphabetical i beginning) be placed on bosom, other 4 simple or compound vowel of a Chinese syllable, around arrangement, make user form one and with finger " counterclockwise ", rotate the mobile custom that just can complete input.For example, input Chinese character word " pride ", can find, on 26 common key full keyboards, the movement of finger is unordered completely, deep memory that need to be to keyboard, the placement position information that coordinates eyes to receive, collaborative fulfiling assignment, and once formation input habit in this layout of the present invention, completes the input of " pride ", quite easy, the stroke of finger, in simple or compound vowel of a Chinese syllable district, is the systematicness motion of twice " counterclockwise ", and this operation can make people after forming preliminary memory, under automatism, complete input.
If take merely the concept of " the initial and the final is separated " layout, but, all simple or compound vowel of a Chinese syllable combinations are all enumerated on keyboard, there will be two defects: first, cause key mapping to surpass 26 keys of English layout, limited because of the area of single key, on a key, arrangement is as the simple or compound vowel of a Chinese syllable combination of " elongated " golygram combinations such as " iang ", just need in the middle of minimum letter, retrieve with eyes, this process is extremely to waste spirit.The second, keyboard layout be difficult to form the sequence of " logicality ", causes all information retrievals by vision, to pass to consciousness completely, or the memory of augmented form completes, and is unfavorable for like this user of preliminary contact.
Run into the combination jointly completing as " an " or " ang " this simple or compound vowel of a Chinese syllable and initial consonant, the present invention has taked a kind of touch screen distinctive " ejection " formula animation, makes input become more succinct, as shown in Fig. 3-Fig. 7.Once point and do not frame out as i.e. contact alphabetical " a ", i.e. so-called " viscosity " input, or in the middle of computerese, be called " long pressing " mode, letter " a " will eject from the left side " an ", from the right, eject " ang " ([note] letter " u " is a special case simultaneously, because only have " un " in simple or compound vowel of a Chinese syllable combination, there is no " ung " so " u " is placed on to the limit of keeping right most, needn't eject the position of " ung ", as shown in Figure 7.) like this, avoided point in the combination of input simple or compound vowel of a Chinese syllable or simple or compound vowel of a Chinese syllable and need to come back to " initial consonant district " and go to select letter, also save the trouble of input " elongated " combination, for example input " in a panic " (cang, huang).
[special case] at the input Chinese phonetic alphabet " er ", when Chinese character " and, youngster, two, ear " etc., for this keyboard layout
Be a special case, must first input simple or compound vowel of a Chinese syllable " e " and then point and get back to initial consonant district contact " r ", so, " e " is arranged in to next line, obtain " r " with initial consonant district as far as possible to press close to, to save finger stroke.
(3) function key region
The function key area of full keyboard, owing to will supplying the left room of letter key, formed function key anisometric " irregular " visual form, and all function keys of this layout be all square etc. large, etc. large function key comprise two punctuation marks often using of input Chinese character ", " and ".", digital switch key " 123 ", Sino-British handoff functionality key " in/English ", and decollator number key " ' " comprises a mark function key " symbol " that accounts for 2/3 key mapping.Other three usual function keys i.e. " backspace ", " space " and " carriage return " have suitably increased area, for 1 and 2/3 of letter key, thereby make the operations such as error correction, confirmation, reversion more intuitively simple and easy, and can when using function key, mistake not press letter key, cause unnecessary confusion.
Secondly, function key all adopts " powder blue " surface, and to distinguish letter key, and this layout, emphasizes out the layout independence in " simple or compound vowel of a Chinese syllable district " and operate independence.
(4) numerical key
Tradition touch screen keyboard is after pressing " numeric keypad switching " (be label be " 123 ") key, screen there will be nine key boards, be respectively digital 1-9, and utilize space therebetween to arrange some function keys, but, often, in the process of Chinese character input, the meaning of digital representative is all relevant to " date " or " calculating ".Although nine key layouts can keep lower mistake to press rate,, often need under numeric keypad and two kinds of patterns of pinyin keyboard, carry out switching back and forth repeatedly.The feature of this layout illustrates above, because the area of single key increases to some extent, so, needn't leave no choice but embody numeric keypad by nine key patterns, the low mistake of guarantee is by rate, so, use at " long press " state and occur nine digital identical keys, initial consonant district pithy formula take that " three or three " be rule " g, k, h, j, q, x, r, w, y " as corresponding " 123, 456, 789 ", using the special simple or compound vowel of a Chinese syllable of the Chinese phonetic alphabet " ü " of middle row is " 0 " key, like this, vacant lower a lot of key mappings in the middle of whole keyboard layout just, utilize these vacant key mappings to form the special area of " directly Chinese character ", can there is respectively expressing " the year of conventional unit in click, month, day, m, cm, mm, %, ℃ " and expression computing formula "+,-, *, /,=, . " or input "-" that " between digital block " used, symbol and " ~ " symbol, all disposable subregion is arranged on screen, as much as possible reduce the number of times that user is switched back and forth.
Sound subregion Chinese character pinyin input method advantage summary
1, its return to China traditional culture custom
The keyboard layout of English 26 keys, in the situation that Chinese use computer for a long time, be rooted in the hearts of the people, but what this layout embodied is " at random " property lexicographic order of Romance, so on common keyboard, we cannot find any " regionality " and " logicality ", in the course of time, Chinese also can lack " sound " separation gradually to marking the letter of own Chinese speech pronunciation, this being divided into two and the aesthetic perception in culture of the distinct Chinese characteristics that two combine into one.Being formed in traditional Chinese culture of so-called " monoyin and monoyang Wei Zhi road " this " negative and positive " is ubiquitous, at Chinese character (standard mandarin), break away from gradually with " pictograph " word or the six scripts and form the standardized today of stroke that is tending towards " symbolism ", the pronunciation of Chinese character can retain the important clue that " initial consonant, simple or compound vowel of a Chinese syllable (or simple or compound vowel of a Chinese syllable combination) " is succession character cultural.Abandon the difference of " the initial and the final ", forget layout that childhood learns very scientific order and " phonetic alphabet " suitable for reading bright and remove to use the alphabetic keypad of a randomness, be obviously not suitable for Chinese custom." custom " be " memory " best helper just, in use, by the help of " custom memory ", can make user realize very soon the pattern with memory area and vision retrieval collaborative work, thereby improve input efficiency.
2, be applicable to the square key interface that finger is clicked
The key interfaces such as the modern life central " telephone key-press ", " coded lock key-press " are ubiquitous, why do all key interfaces all adopt the closely design of " square "? people's vision is more acceptant positional information in the square button of retrieval, finger is because surface of contact comprises finger tip completely when touching by square button, and the probability of makeing mistakes is also very little.But because existing " English 26 keys " key mapping will be applicable to the keyboard form of computing machine (typewriter), single button will be contained in a similar foursquare region, just must be designed in a rectangle of present " setting " formula presenting, this causes QWERTY keyboard to be unfamiliar with, it is very difficult that retrieval key mapping is found letter only according to the user of vision, and the slightly thick user of finger often pushes the wrong the letter of adjacent position." the initial and the final zoning " can make each letter key become the square that applicable finger taps, and partition system logicality is strong, also can help user to form key mapping memory.
3, super easy simple or compound vowel of a Chinese syllable combinatorial input
The rule of the Chinese phonetic alphabet very simple and easy (except minority Chinese characters such as " er " mentioned above), may be summarized to be " the many rhythms of a sound " substantially, and this is also the reason that Tang poems and Song ci has unique music aesthetic feeling.Yet in Pinyin Input, user is by the initial consonant that is over, also need under full key board position, retrieve, if a phonetic is as " niang " (Chinese character " ma "), clearly, the required work of paying of brain is in 26 key mappings, to carry out 5 times retrieve and react.This is obviously irrational." sound zoning " substantially provides such information retrieval rule, and for " n ", vision actual retrieval scope is " the second row ", because pithy formula is " d, t, n, l ", initial consonant is 4 to select 1 so.Simple or compound vowel of a Chinese syllable district just only had 6 (comprising ü) in fact only need in the middle of 5, select " i " originally, then selected " a ", had just completed current input, and simple or compound vowel of a Chinese syllable is 5 to select 2 so.This information retrieval system obviously likens 5 times 26 to select 1 simply too much.In principle, sound subregion input method, although utilize exactly the simple or compound vowel of a Chinese syllable of the Chinese phonetic alphabet often to need combination, but simple or compound vowel of a Chinese syllable only has altogether 6, the feature of this " congenital ", gives separately simple or compound vowel of a Chinese syllable a separated specific region, in any case combination (except ü), all only need be in one " nine grids " inner the completing of " cross ", so just greatly simplified the process of combinatorial input.The short essay of 500 words of statistics, for former 26 key boards, the retrieval number of times average out to that brain is paid selects 1 1625 times 26, even and if " initial consonant pithy formula " completely formed to the user of memory, also only need pay average 500 times 20 selects 1, and 500 times 5 are selected 2.12.So, the process of information retrieval is simplified, and the perfection of actuation of keys completes number of times and is enhanced in addition, and input is originally so not painful.
