Description

A kind of input method of mixing based on the words of button and stroke

[technical field]

The present invention relates to a kind of Chinese character input method of electronic message unit, relate in particular to a kind of by the palm electronic message unit keypad and with the mixed input method of individual character and word in the coding angle of stroke and search channel, the realization Chinese character.It can be applicable to the Chinese character input field of portable keypad electronic message units such as telepilot, game machine, cell-phone, palm PC, electronic dictionary, digital camera, electronic notebook, personal digital assistant.

[background technology]

When people carry out the Chinese character input on the keypad of electronic message units such as cell-phone at present, in the known method that is adopted, the type of basic input scheme has varied: in key-press input method, the method by Pinyin coding is arranged, the method by stroke coding is also arranged; In the method for stroke coding, the method for single Chinese character input is arranged, also there is words to mix the method for input; Even in the words mixed input method, multiple different design proposal is arranged also.

With respect to handwriting input and phonetic entry, on the basis of current the most common button Chinese-character input scheme, can adopt the stroke of Chinese character to constitute and stroke along as clue, carry out the coding retrieval with Chinese character of being pre-created of code book, and and then individual character in the Chinese and word mixed ground Unified coding, the unified input.In the background technology of this special Chinese-characters input is in the Chinese-character input scheme that mixes of button realization, stroke coding, words, at present common technical characterictic have following some:

---utilize a plurality of buttons in the keypad, realize the operation of Chinese character input, these a plurality of buttons can relate to numerical key, directionkeys, acknowledgement key etc. usually;

---according to coding rule designed in the input method, utilize the button of appointment, participate in each basic stroke type of coding in input individual character or the word, or Chinese character component parts such as radical, radicals by which characters are arranged in traditional Chinese dictionaries, radical;

---use a kind of prepare word tabulation, operation interface as input method, it will enumerate out in the input method code library, meet all individual characters and word by the current search key condition of having imported of keypad, when importing without any search key, the prepare word in the prepare word tabulation just shows as all individual characters and the word in the whole input method code library;

---in the prepare word tabulation, use the method for digital keys numbering, the method for perhaps using cursor to highlight positions sign to each words option, so that the operator is to the selected input of specific words option;

---at the stroke coding with words is clue, during to the retrieval of prepare word tabulation carrying out words, retrieval code position of common every increase input, prepare word tabulation all will carrying out time Refresh Data, and along with the continuous input of retrieval code position, the quantity size of the prepare word in the prepare word tabulation will be with exponential velocity attenuation;

---in the current page of prepare word tabulation showed, when the words that will import occurred, the operator can finish the operating process of a basic words input with its selected input;

---in view of the words quantity in the prepare word tabulation more, the prepare word tabulation comprises a plurality of pages usually and needs split screen to show page by page, in the stroke retrieving and words is selected finish after, only the homepage of acquiescently current prepare word being tabulated is presented in the screen, but can carry out forward and backward page turn over operation to it where necessary.

Be accompanied by the development trend of portable electric appts miniaturization, its keyboard becomes more and smaller and more exquisite, makes that the interval of button is compacter, and the surface of button is narrower and small, and prints littler numeral and alphabetical at key-top.Regrettably, the operator of these electronic equipments meets difficulty sometimes in identification or when pushing the button of those narrow and small and compact arrangements in surface, causes easily once pressing a plurality of keys or pressing the wrong button.For cell-phone and other portable electric appts, exist these defectives, therefore the total quantity of button that need the input Chinese character is involved reduces as best one can.Meanwhile, people to the requirement of the simplification of Chinese character input in the electronic equipment and speed also more and more higher.

In the various Chinese-character input scheme that exists at present, cut both ways usually.But with regard to the scheme that the background technology that aforementioned special Chinese-characters is imported is button realization, stroke coding, words mixing, although it has the diversified form of expression, also ubiquity that the number of keys that relates to is more, the type of coding unit is not easily distinguishable, coding rule is too complicated, the selected inconvenience of prepare word, Chinese character input speed waits weak point more slowly.

[summary of the invention]

The present invention has overcome deficiency of the prior art, and a kind of input method of mixing based on the words of button and stroke is provided.Its objective is, whole operation process with the Chinese character input, be implemented in the keypad and concentrate on a small amount of several buttons that distribute and be convenient to operate, break away from this that the vision to button relies in Chinese character input process, and improve the button operation speed in the Chinese character input process; While rational word coding method scheme of design science and button operation rule, the code efficiency of increase key is to reduce the touch potential in the Chinese character input process as far as possible; And realize the quick input in Chinese pattern that words mixes.Generally speaking, the objective of the invention is to improve the convenience of character input operation in the keypad palm information equipment.

To achieve these goals, the present invention solves by the following technical programs.

(1) utilizes at the button of Chinese character input

(1) individual character no matter, or word, its input process all are implemented in the keypad on a spot of several buttons.These a spot of several buttons mainly are meant five key groups, and this five keys group is concentrated on keypad and distributed, and it is made of five buttons that are distributed in upper and lower, left and right, middle position relatively; Some other function key distributing position on keypad of realizing booster action does not then have specific (special) requirements, because they relatively less use in Chinese character input process usually.

(2) when five key groups are carried out button operation, in order to realize the multiplexing functions of same button, will be referred to three kinds of button operation modes promptly press, long by, two by among by two kinds of appointment arbitrarily.Difference between three kinds of button operation modes is: press and be operating as basic button operation; Long be different from the duration and press operation by operating in button; Twoly be different from interval time and press operation by operating in button.

(2) on the stroke coding of Chinese character input

(3) individual character no matter, or word, in its stroke coding constituted, all stroke formation and the stroke order with Chinese character was clue, and was horizontal, vertical, left, points, discount with five kinds of basic stroke types, as five stroke coding units.

(4) for individual character, the formation of the stroke coding that it is complete definition is, constitutes the coding sequence that is determined with stroke order, all stroke coding positions are connected in sequence by the stroke of whole Chinese character.

(5) for word, the formation definition of the stroke coding that it is complete is, according in aforementioned about the formation definition of the stroke coding of individual character, all stroke coding positions during the stroke coding position of at least one that extract separately in being made of the complete stroke coding of each non-ending Chinese character of other except that last Chinese character in the word and the complete stroke coding of ending Chinese character constitute, the coding sequence that is connected in sequence.Here define among all stroke coding positions of complete stroke coding of a word of described formation, with the corresponding stroke coding of an ending Chinese character position, be exactly all the stroke coding positions during the complete stroke coding of its individual character self constitutes, clearly limit herein; But with the corresponding stroke coding of each non-ending Chinese character position, the bits of coded of at least one in only being defined as the stroke coding formation, and its particular location and quantity in this stroke coding constitutes, there is no clearly herein and limit, although they will clearly limit in concrete case study on implementation, and relevant with designed specific coding rule.

(3) on the input scheme that words mixes

(6) prepare word tabulation in its each page, has four candidate item that are embodied in individual character or word as the operation interface of Chinese character input, and they go to upper and lower, left and right relative position distribution.

(7) prepare word tabulation is as the operand of Chinese character input, in the words input process, can carry out to it that stroke retrieval, words are selected, three kinds of button operations of tabulation page turning.

(8) in the stroke retrieval of words input, individual character and word are retrieved uniformly comprehensively, they are all as the base unit of Chinese character index, and all as the structure element of input method character word stock, jointly form the complete or collected works of each words that input method can import.

(9) in result's demonstration of prepare word, demonstration enumerated uniformly in individual character and word, the base unit that they are all imported as Chinese character, and all as the composition option of prepare word tabulation, be presented among each page of prepare word tabulation with mixing.

(10) promptly press at three kinds of key modes of five key groups, long by, two by among, choose any two kinds of different key code environment that are used separately as button operation, five key groups under a kind of therein key environment all are used for the stroke retrieval, and the four-way key under another kind of key environment is used for the page turning backward that words is selected, center key is used to tabulate.By distinguishing two kinds of different key environment,, finally realize the functional diversities of same button like this to enrich the key value.

(11) when stroke is retrieved, stroke coding according to the individual character that will import or word constitutes, key mode by certain appointment of five buttons in the five key groups, import five kinds of stroke coding positions of horizontal, vertical, left, points, discount in its stroke coding formation respectively successively, and satisfying under the precondition of one-to-one relationship, these five stroke coding units distribution mode on five buttons in five key groups is arbitrarily.

(12) when words is selected, the position, residing upper and lower, left and right in prepare word tabulation current page according to the individual character that will import or word, by the corresponding button in position, upper and lower, left and right with it in the four-way key, and utilize the key mode of certain appointment of this button, with target individual character or the selected input of word.

(13) in tabulation during page turning, according to the needs of searching to the individual character that will import or word, the key mode of certain appointment by center key is to prepare word tabulation carrying out page turning backward.The page turning of prepare word tabulation, mostly just as a kind of supplementary means of words retrieval, but it should have two kinds of functions of page turning forward and page turning backward simultaneously, here only mentioned the page turning backward of prepare word tabulation, as for its page turning forward, can use other flexible and changeable implementation method, in concrete case study on implementation, will describe in detail.

It more than is technical scheme of the present invention.Compared with prior art, beneficial effect of the present invention mainly shows as the high efficiency and the dirigibility of the input of keypad Chinese character.

[embodiment]

To be example below with the cell-phone, from four aspects, and in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail.

(1) the button utilization of importing about Chinese character

(1) routine of keypad distributes

In Fig. 1, provided in the present cell-phone keypad, the exemplary distribution mode of part button, these buttons have related to navigation key, numerical key, function key altogether, and they are respectively described below:

Navigation key among this figure is commonly called five navigation key again.In view of the relative position distribution of five buttons in the navigation key, in the text editing input of small keyboard information equipment and function menu were browsed, they were generally used for the feature operation that realizes that cursor moves and menu is selected.

Numerical key among this figure has comprised the 10 numeric keys of 0-9.In common small digital keyboard, this 10 numeric keys will distribute with the position form of standard.

Function key among this figure has related to clear key, soft key, * key, # key.Clear key wherein is commonly called title forms such as CLR key, C key, return key, ESC Escape again; Soft key wherein has two usually in cell-phone, and is positioned at the top of keypad, defines its keypress function under current operation status by software flexible, and gives brief description by the label literal of row at the bottom of the screen; * key wherein and # key are because they in the specific embodiment of the present invention, can be used to the feature operation of appointment, i.e. the switching of input state here why as function key.

The formation definition of (2) five key groups

In enforcement of the present invention, will mainly use one five key group, realize the Chinese character input process that words mixes.

Five key groups only are made of five buttons, and these five buttons go to upper and lower, left and right, in the cruciform relative position distribution, its distribution shape is as shown in Figure 2.In whole five key groups constituted, it comprised four-way key and center key, and four-way key wherein specifically comprises key, time key, left button, right button again, the middle key that is otherwise known as of center key wherein.

The cruciform button of five key groups above-mentioned distributes, its implication only is the button formation of five key groups and the relative position arrangement between each button, the external appearance characteristic as five key groups of specific embodiment that provides in Fig. 2 does not limit the wherein concrete shape of each button.Therefore, after art designing's design of the shape of these five buttons being carried out variety of way, will belong within the concept field of five key groups of the present invention.

In the Machine Design of five key groups, for structural compactness and the operation suitability that improves button in the five key groups, should consider in the five key groups distribute spacing problem between five buttons, if upper and lower, left and right, in five buttons are independent distribution separately, so wherein the center of four of upper and lower, left and right buttons is with respect to the distance between the center of center key, the comfortable operation that all should be adapted to point; In five key groups, on the tactile feedback of five buttons, should make five key groups that suitable button feel can be provided in addition by appropriate Machine Design.

Each button in the five key groups in Machine Design except independent distribution separately, also can they are integrated, be about to whole five key groups mechanically one turn to one five to the lever-type button, it also can be pressed downwards except the four-way of upper and lower, left and right is pressed; Also the upper and lower, left and right key in the five key groups mechanically can be designed as a whole, and center key independent distribution only.With upper and lower, left and right in the five key groups, in five buttons fully or partly, in Machine Design, be integrated in one, the mechanical features that can meet five key groups described above equally, therefore also be to carry out the Chinese character input as five key groups involved in the present invention, and the button of integrated form will be more convenient flexible when operation.

In a word, the above-mentioned mechanical features of five key groups shows that the quantity of five buttons is to be convenient to be familiar with for people; The residing upper and lower, left and right of each button, in relative position also be to be convenient to people grasp; Compact button distributed architecture can be for shortening finger (being generally thumb) displacement and elapsed time on keypad in Chinese character input process; The button moulding meeting of having strengthened the feel design provides good tactile feedback for the user.All these are the user to the handled easily of five key groups, especially for being that " blind " operation (not seeing button) provides useful help, thereby provide possible condition for carrying out Chinese character input fast, consistently.

In Chinese character input process, the benefit that " blind " change mode of operation of button is brought is, the vision of having broken away from button because of the user relies on, and has also avoided the continuous switching of sight line between keyboard and screen, thereby sight line can be concentrated entirely on the prepare word tabulation on the screen.Therefore, also there is not to import the prepare word that finishes and just in the prepare word tabulation, occurred for its stroke coding, make things convenient for the user in the very first time, it directly to be carried out the selected operation of words as much as possible, and avoided this unessential unnecessary stroke code position to continue the situation of input.

By the mechanical key of pressing operation, the touch key-press by induction control for novel can constitute the five key groups that satisfy upper and lower, left and right, middle position distribution characteristics equally, and utilize this five keys group to carry out character input operation except traditional.

The form of expression of (3) five key groups

Five key groups of crossing distribution belong to an ingredient on the electronic message unit keypad.Fortunately, on the keypad of current electronic message unit especially cell-phone, exist five key combinations that its distribution shape meets " upper and lower, left and right, in " feature.Specifically be exactly that the distributing position of five key groups on whole keypad can show as one of three kinds of following forms:

The first, five key groups are distributed on five navigation key in the keypad.Can directly utilize five common in the keypad of current electronic message unit navigation key, carry out Chinese character input involved in the present invention.Five navigation key are the one group of related key that is distributed as upper and lower, left and right, middle position relatively, and it is usually located at the top of keypad in cell-phone.

It two is, five key groups are distributed on " 2-8-4-6-5 " or " 5-0-7-9-8 " numerical key combination in the standard numeric keyboard.On standard numeric keyboard, 10 numerical keys of 0-9 and 2 function keys of * and #, usually with the array distribution of 4 (OK) * 3 (row), and five numerical keys " 2-8-4-6-5 " in them or " 5-0-7-9-8 " have all constituted the relative distribution shape of cruciform of " on-down-L-R-in " just, meet the distribution characteristics of five key groups involved in the present invention and constitute definition.

It three is, five key groups are distributed on five membrane keyboards combinations of going to upper and lower in the keypad, left and right, middle position arrangement.Five key groups can also show as novel touch key-press except showing as traditional mechanical key, and utilize the mode of touch sensible to control button operation.

When five key groups are positioned on five navigation key, its great advantage is, this is exactly that compact conformation, feel are good usually in Machine Design for five navigation key in the electronic equipment keypad, and it can be for the present invention directly uses, and gives the additional functionality that its Chinese character is imported.Especially when Chinese character input method of the present invention is applied to cell-phone, when utilizing five navigation key on the keypad top that is positioned at it and utilizing thumb to carry out character input operation, controlled phone easilier by the user; Simultaneously, because this Chinese character input method does not take the numerical key resource on the keypad in this case, therefore can be implemented under the situation of not switching this input method of Chinese character state, directly utilize numerical key to carry out numeral and import or utilize numerical key not use the input method of Chinese character of five navigation key to carry out the Chinese character input with other.But on the other hand, a unfavorable factor when five key groups are positioned on five navigation key is, when text editing, five navigation key are between character input function of newly giving and the former conventional defined function that has, tend to produce the conflict by on the key definition, this conflict need be managed to solve separately.

The mode of operation of (4) five key groups

Button operation for five key groups among the present invention, will be referred to three kinds of modes promptly press, long by, two by among by two kinds of appointment arbitrarily, in realizing running software of the present invention, corresponding to these two kinds of different key modes of same button in the five key groups, will produce each self-corresponding program reaction.Above-mentioned three kinds of key modes are explained as follows respectively:

To " pressing " operation of button, be basic, the most general a kind of key mode.The definition of this " pressing " should be a prerequisite not conflict mutually with the definition of following " length is pressed ", " two pressing ", promptly in the definition of this " pressing ": in order to be different from " long pressing ", should promptly unclamp after button is pressed; In order to be different from " two pressing ", must not be pressed once more within the utmost point short time period of same button after being pressed.In an embodiment of the present invention, normal conditions are for the feature operation that relative high frequency is used, will use this button operation mode.

" long by " operation to button is meant and presses certain button, and the state that always keeps this button to be pressed within the defined sufficiently long time period at a software.With by the bond distance by corresponding programs reaction this time elongate member take place automatically after satisfying, whether unclamped irrelevantly with button at that time, the operator can refresh by the demonstration of screen, knows that current length enters into force by operation.In an embodiment of the present invention, normal conditions are for the feature operation that relative low frequency uses, will use this button operation mode.

" two pressing " operation to button, be meant and press certain button continuously twice, and within the time period of the time interval between pressing for twice less than a defined enough weak point of software, this " two pressing " operation is very similar to " double-click " operation of computer mouse.Two with button is to take place automatically pressing the second time of satisfying this time interval condition after by the corresponding programs reaction, and the operator can refresh by the demonstration of screen equally, knows that current pair enters into force by operation.In an embodiment of the present invention, normal conditions are for the feature operation that relative low frequency uses, will use this button operation mode.

When five key groups showed as five touch key-presss, the implication of above-mentioned three kinds of button operation modes did not have essential change, and the action when being button operation changes touch into by pressing, keeps touching, changing continuous touch into by pressing continuously by keeping pressing changing into.

In the present invention, above-mentioned three kinds of different key modes only are aimed at five buttons in the five key groups.Key mode for other button in the keypad does not limit, and does not do special instruction yet.

(2) stroke coding of importing about Chinese character

(1) use of basic stroke coding unit

Word involved in the present invention, speech input method are on the basis of the related specifications that meets the national language literal, the encode Chinese characters for computer that foundation is easy to learn and use.It is categorized as known five kinds with the basic stroke of Chinese character: horizontal stroke (is expressed as one, contains and carry

), perpendicular (be expressed as Shu, contain Shu Gou 亅), cast aside (being expressed as Pie), point (is expressed as Dian, contains right-falling stroke ), the folding (Biao Shi is Ya, comprises a various foldings stroke, as: Ya, Yin,

く ...), and constitute and stroke order according to the stroke of Chinese-character writing, words is encoded; On the other hand, also will be as clue, the stroke search operaqtion when carrying out the words input.In a word, no matter individual character, or word in its coded system and retrieval mode, all is that the stroke according to Chinese character constitutes and stroke order, with five kinds of basic stroke types of horizontal, vertical, left, points, discount, as the coding of words and five stroke coding units of retrieval.

In the stroke coding of word, speech, utilize five kinds of basic stroke types of known Chinese character, be five stroke coding units of horizontal, vertical, left, points, discount, and the stroke and the order of strokes observed in calligraphy during according to Chinese-character writing are encoded to words, in the stroke coding of words constituted, each stroke coding unit all showed as a stroke coding position.We can say that bits of coded is the minimum code unit during stroke coding constitutes, coding unit then is the summary to the fundamental type of bits of coded.

The stroke coding of word, speech based on the stroke of each Chinese character constitute and stroke order, should be with relevant national standard and industry standard as the reference foundation.Need to prove simultaneously, convenience for describing word, speech stroke coding, five numerals of " 1 ", " 2 ", " 3 ", " 4 ", " 5 " will be used in the back, five kinds of basic stroke types representing " horizontal stroke ", " erecting ", " left-falling stroke ", " point ", " folding " successively respectively accordingly, so in the stroke coding of representing with numeric string constitutes, each numeral will be represented a stroke coding position.

(2) coding rule of individual character and word

For individual character and word, employed coding rule is described below respectively.In the process of words input, also should carry out the stroke search operaqtion according to the clue of following coding rule.

For individual character, the formation of the stroke coding that it is complete definition is, constitutes the coding sequence that is determined with stroke order, all stroke coding positions are connected in sequence by the stroke of whole Chinese character.

For word, the formation definition of the stroke coding that it is complete is, according in aforementioned about the formation definition of the stroke coding of individual character, all stroke coding positions during the stroke coding position of at least one that extract separately in being made of the complete stroke coding of each non-ending Chinese character of other except that last Chinese character in the word and the complete stroke coding of ending Chinese character constitute, the coding sequence that is connected in sequence.

Define in front among all stroke coding positions of complete stroke coding of a word of described formation, each non-ending Chinese character all provides the stroke coding position of at least one, but this at least one stroke coding position, particular location and quantity in the complete stroke coding of its individual character self constitutes, all be regarded as the key element of refinement undetermined, and can derive various specific coding schemes thus.Because this at least one stroke coding position in the complete stroke coding of its individual character self constitutes, can be continuous, also can be discontinuous; Being equally under continuous situation, can be to be positioned at head, also can be to be positioned at middle part or afterbody; Be equally continuously, be positioned under the situation of head, the quantity of the stroke coding position that each non-ending Chinese character is extracted can be changeless, also can be mutually different.As a kind of case, for word, the formation definition of the stroke coding that it is complete is, according in aforementioned about the formation definition of the stroke coding of individual character, be arranged in all stroke coding positions that the complete stroke coding of the stroke coding position of top fixed qty and ending Chinese character constitutes in constituting by the complete stroke coding of each non-ending Chinese character of other except that last Chinese character in the word separately, the coding sequence that is connected in sequence; And to each non-ending Chinese character the fixed number value that is positioned at top stroke coding position of intercepting separately, be one more than or equal to 1 and smaller or equal to 4 integer; In addition when the total length of the stroke coding of non-ending Chinese character during less than this fixed number value, all the stroke coding positions in getting then that the whole stroke coding of this non-ending Chinese character is actual and constituting.

In front, the prefix of regular length in the complete stroke coding of non-ending Chinese character each, during as the ingredient of the complete stroke coding of whole word, although the numerical value of this regular length has been constrained within the integer range of 1-4, but, will exist the prefix intercepted length and be respectively four kinds of different schemes of 1,2,3,4 according to the difference of this concrete numerical value.As a kind of more specifically case, in the formation definition of the complete stroke coding of word, to the complete stroke coding of each non-ending Chinese character wherein, the fixed qty that is positioned at top stroke coding position that institute intercepts separately, value is 2.If no special instructions, the word coding under the described hereinafter various for example situations all will adopt this prefix intercepted length to be fixed as 2 scheme.

In the narration of superincumbent word coding method rule, can learn by contrast, individual character no matter, or word, all be that last Chinese character is wherein got its complete stroke coding and the prefix part that its stroke coding only got in each Chinese character before its, so aforesaid coding rule to individual character and word is consistent in itself, to the coding rule of individual character just to a kind of extreme case of the coding rule of word.

Usually,, in the input method code book, need to preserve its complete stroke coding, because according to the requirement of match retrieval, all stroke code positions of any one words all are indispensable in the input method code book for the coding of words; And for the retrieval of words, in the button input process of stroke coding, then unnecessary its all stroke code position of using, because before all stroke code position inputs are finished, the words of importing just might appear at and be used for having there is no need to continue the more stroke code of input position this moment among the current screen acquiescence homepage that show, that prepare word is tabulated.

(3) coding of individual character and word for example

For above-mentioned concrete word coding method rule, illustrate as follows.It should be noted that, in the stroke coding of the more occurring words examples of following word example and back is represented, junction symbol "-" itself is not as the ingredient of word stroke coding, it only be for read identification just, be used for segmentation and represent the pairing stroke coding of each individual character of word position.

The complete stroke coding of individual character " state " is defined as " 25112141 ", this stroke coding is the complete stroke coding position by " state " word, connect the sequence (perpendicular folding horizontal stroke is horizontal anyhow horizontal) that is constituted successively, when the stroke retrieval of individual character " state ", also should import its each bits of coded successively with this clue of encoding;

The complete stroke coding of word " motherland " is defined as " 45-25112141 ", this stroke coding is by preceding two stroke coding positions of " ancestral " word, the complete stroke coding position of " state " word, connect the sequence (some folding-perpendicular folding horizontal stroke is horizontal anyhow horizontal) that is constituted successively, when the stroke retrieval of word " motherland ", also should import its each bits of coded successively with this clue of encoding;

The complete stroke coding that word " is loved one's country " is defined as " 34-45-25112141 ", this stroke coding is by preceding two stroke coding positions of preceding two stroke coding positions of " love " word, " ancestral " word, the complete stroke coding position of " state " word, connect the sequence (apostrophe-perpendicular folding of a folding horizontal stroke is horizontal anyhow horizontal) that is constituted successively, when the stroke retrieval that word " is loved one's country ", also should import its each bits of coded successively with this clue of encoding;

The complete stroke coding that word " has ardent love for the motherland " is defined as " 12-34-45-25112141 ", this stroke coding is by preceding the stroke coding position of preceding two stroke coding positions of preceding two stroke coding positions of " heat " word, " love " word, " ancestral " word, the complete stroke coding position of " state " word, connect the sequence constituted (anyhow-an apostrophe-folding-perpendicular folding horizontal stroke is horizontal anyhow horizontal) successively, also should import its each bits of coded successively when the stroke that " has ardent love for the motherland " at word is retrieved with this clue of encoding.

In word coding, if the stroke sum of non-ending Chinese character less than specified coding prefix intercepted length, so then the stroke coding length with this word reality is as the criterion.For example in word " ", two of the stroke of non-ending Chinese character " " sum less thaies are then only got its unique stroke coding position " 1 ", and the stroke coding formation of whole word " " is " 1-342 "; Similarly, the stroke coding of word " on the other hand " constitutes " 25-1-41-132522111 ", and the stroke coding of word " Party B " constitutes " 5-4153 ", and the stroke coding of word " tygon " constitutes " 12-5-43343413252 ".

(3) input scheme that mixes about words

(1) prepare word tabulation

The prepare word tabulation is the operation interface of Chinese character input, and in the whole Chinese character input process after entering this Chinese character input method, the prepare word tabulation exists all the time.

The prepare word tabulation is meant, according to the current stroke coding string of having imported as search key, each individual character that the operator who is predicted by system intelligence in whole input method character word stock imports possibly and the tabulation of word, may be more in view of the quantity of the candidate's individual character in the prepare word tabulation and candidate's word, it often comprises a plurality of pages and needs split screen demonstration page by page.

The prepare word tabulation is selected each individual character of input or the tabulation of word as current for the operator, each words that is arranged among the tabulation of current prepare word all satisfies such coding retrieval character: the whole stroke coding of words or the prefix part of its whole stroke coding (one or more continuous programming codes position that stroke coding starts), and identical with the current stroke coding string of having imported as search key; When importing without any the stroke code position, the words option in the tabulation of current prepare word constitutes, and just is the complete or collected works of character library and dictionary in the input method.

In case enter this input method of Chinese character state, the prepare word tabulation occurs at once and exists all the time, the existence of prepare word tabulation can provide various facilities for character input operation: at first, when it will be imported for words without the selected possibility that provides of stroke retrieval directly carrying out words; Secondly, it will cushion the matching operation between the two of stroke input and result for retrieval and concern; Once more, it will help to handle the input problem of the words that stroke coding is identical or prefix is identical.

The prepare word tabulation often is made of a plurality of prepare words, so it usually needs, and multipage is preserved, page turning shows.In each page of prepare word tabulation, show four words altogether as candidate item, and they go to upper and lower, left and right relative position concentrates and distributes, as shown in Figure 3A.

On the corresponding relation between four prepare words in four-way key in five key groups and the screen display, set up the direct mapping between the two by this method---the relative position of each prepare word in its original list promptly represented the relative position of four-way key in five key groups of selected this words, and such location map relation will make the selected operation of words become very directly perceived.In the input process of words, can be by the four-way key of the upper and lower, left and right in the five key groups, respectively in the current prepare word original list of selected successively input with the corresponding candidate's individual character in their positions, upper and lower, left and right or candidate's word.Like this, be the shape-designing of prepare word tabulation by operation interface to the words input, be equivalent to each prepare word in the page has been carried out being convenient to especially the selected secondary coding of importing, because it provides direct key position information towards button operation.

Three of the distribution shape of four prepare words kinds of distortion in the prepare word original list are shown in Fig. 3 B, Fig. 3 C, Fig. 3 D.In these three kinds of distortion, though the relative position distribution of the upper and lower, left and right between four word candidate item is expressed intuitively obviously not as Fig. 3 A like that, but they all only take the display space of two line characters, with respect to three line characters of Fig. 3 A, they can be the display space that screen is saved delegation.

In a word, the above-mentioned appearance attribute of prepare word tabulation shows that the capacity of four words of every page of demonstration can be accepted by people's field range easily in the prepare word tabulation; Simultaneously, four prepare words in the prepare word original list are the distribution shape in four orientation, these four prepare words can be correspondingly and are equally in the five key groups between the four-way key that four orientation distribute and set up a kind of relation of location map intuitively, to be convenient to the selected operation of words.

Various concrete button operation in whole words input process all is to be center object with the prepare word tabulation, and its elementary object all is that the words that will import is called within the text input editing district from the prepare word tabulation.Button operation for the prepare word tabulation has three types: stroke retrieval, selected, the tabulation page turning of words are described below respectively them.

The stroke search operaqtion refers to, and constitutes according to the stroke coding that will import words, imports its each stroke coding position successively, and with this as key condition, the words that retrieval will be imported in current prepare word tabulation.In the words input process, along with the continuous input of the stroke code position of words, all words in the existing prepare word tabulation are also carrying out constantly retrieval.Each words that will meet the retrieval requirement continues to remain in prepare word tabulates, will superseded disappearance from tabulation and meet the words of retrieving requirement.Continue to remain in being still of tabulation with the current stroke coding string of having imported all words for the prefix part of its stroke coding or its stroke coding, therefore stroke code position of every input, the prepare word tabulation also will be upgraded immediately.When the code element number that participates in word coding method is 5, in the ideal case, the number of words in the prepare word tabulation will be dwindled (length that N is the stroke coding imported) with the rate of decay of (1/5) N.In the process of stroke retrieval, the current page that is used for the prepare word tabulation of screen display always points to its homepage acquiescently.

The selected operation of words refers to, to appearing at the words that to import in the prepare word tabulation current page, utilize the visual location corresponding relation between four prepare words and the four-way key, it is inserted into the current cursor part of input text area by corresponding key operation.When the words that will import has come across the current page of prepare word tabulation, need this button operation, and words selected be all requisite operation steps in arbitrary words input process because it is representing finally finishing of words input operation.

The tabulation page turn over operation refers to, when prepare word factor amount more and have a plurality of pages and the words that will import when not appearing in the current page, can be by button operation to the forward and backward page turning of prepare word tabulation carrying out, searching the words that will import page by page, and the page turning forward of tabulation is reciprocal with page turning backward.The use occasion of the page turning backward of tabulation normally, in the stroke retrieval, when the operator is difficult to grasp to importing the difficult or stroke order of some stroke types identification in the words, and the continuation of having interrupted the stroke code position is imported, simultaneously too many because of the very few prepare word that causes in the stroke code position of being imported, and it is when failing to appear at the current homepage of prepare word tabulation; And in stroke retrieval, though all imported and finish when importing all stroke code positions in the words, more because of the repeated code words, and it is when failing to appear at the current homepage of prepare word tabulation.

Three kinds of button operation types described above are complementary, and they can carry out mutually across in the words input process, and under arbitrary state of prepare word tabulation, all can carry out in these three kinds of button operation types any one.What need explanation a bit is, in the process of words input, for the words that will import is come across among the current page of prepare word tabulation, can be by the mode of stroke retrieval, can be to improve the words input efficiency also, the words that import is appeared among the homepage of prepare word tabulation as soon as possible by the mode of searching of page turning backward of tabulation, should retrieve it by the method for input stroke code position as much as possible, rather than search it by the method for tabulation page turning.This be because, the input of stroke code position belongs to a kind of index search mode, and the tabulation page turning then belongs to a kind of block research mode, and the former can dwindle seek scope with exponential speed, the latter then only dwindles seek scope with linear speed, and the former efficiency of algorithm is than latter height usually.So, even the words of importing is association's words of a last input words, but because the more and words that will import of association's words quantity of a last input words is when failing to be arranged among the homepage of prepare word tabulation, for improving input efficiency, also should try one's best and not use or at first do not use the mode of page turning to search it, but preferentially use the mode of stroke retrieval to search it.

Before the button operation that the retrieval of stroke in arbitrary words input process, page turning are searched, the prepare word residing state of tabulating is referred to as original state.The original state of prepare word tabulation is embodied in: after entering this input method of Chinese character state and do not carry out the state of any button operation; Or after just finishing and do not carry out the state of any button operation to the selected input of a words; Or in the process of stroke retrieval, be judged as the state that illegally causes tabulating after automatically reseting through system because of the stroke coding of being imported; Though or in the process of word lookup, carried out the operation of stroke retrieval or tabulation page turning but be eliminated and state after the hand-reset that causes tabulating.Under original state, the words option in the prepare word tabulation constitutes, and is the whole character library of this input method and the complete or collected works of dictionary, and the current screen homepage of show candidate words tabulation acquiescently only.

In the arrangement that puts in order between each prepare word in the prepare word tabulation, according to priority order from high to low, the cardinal rule that should follow is: Pi Pei words is positioned at before the words of prefix matching fully; The words of association is positioned at before the words of non-association; The words that high frequency uses is positioned at before the words of low frequency use.

In addition, though will be according to above-mentioned cardinal rule to all individual characters in the input method character word stock and word mixing ordering, but with regard to above-mentioned " words that high frequency uses is positioned at before the words of low frequency use " this concrete principle, relative sequencing between each words is not unalterable, they can constantly dynamically be adjusted along with the input process of operator to different words fully.Its objective is by adapting to operator's words use habit, just pass through the real-time change of words usage frequency, to improve the efficient of its words input more easily at particular operators.

(2) unitarity of words

In the present invention, individual character and word all are base units of Chinese character input, so in the character library and dictionary of input method, need carry out uniformly the stroke retrieval, and will meet all individual characters of the retrieval character of encode and word in the two uniformly as awaiting selecting the words of importing to the two.

In the present invention, individual character is meant single Chinese character; Then for individual character, it is made of the Chinese character more than word, and it is usually expressed as multi-character words, phrase is phrase or even common sentence etc.

At first, in the stroke retrieval of words input, individual character and word are retrieved uniformly comprehensively, they are all as the base unit of Chinese character index, and all as the structure element of input method character word stock, jointly form the complete or collected works of each words that input method can import.In the stroke retrieval of words input, the input of its stroke code position should be carried out respectively according to they coding rules separately, and needn't carry in the key of being imported and be used to specify the Chinese character type of being imported is the individual character or the characteristic information of word.

Secondly, in result's demonstration of prepare word, demonstration enumerated uniformly in individual character and word, the base unit that they are all imported as Chinese character, and all as the composition option of prepare word tabulation, be presented among each page of prepare word tabulation with mixing.As long as meet the search condition feature of the current stroke code position of having imported, no matter be individual character, or word, they all will be contained among the current prepare word tabulation as basic candidate item.

(3) character and word input method

In operation to five key groups, Ying Zaisan kind key mode promptly presses, long by, two by among, choose any two kinds of different key code environment that are used separately as button operation, five key groups under a kind of therein key environment all are used for the stroke retrieval, and the four-way key under another kind of key environment is used for the page turning backward that words is selected, center key is used to tabulate.To form the concrete scheme of following six kinds of different arrangement modes for this reason:

Press five key groups and be used for the stroke retrieval, it is selected that length is used for words by the four-way key, the long page turning backward that is used to tabulate by center key;

Press five key groups and be used for stroke retrieval, two to be used for words by the four-way key selected, two page turnings backward that are used to tabulate by center key;

Long be used for the stroke retrieval by five key groups, pressing the four-way key, to be used for words selected, presses the page turning backward that center key is used to tabulate;

Long be used for the stroke retrieval by five key groups, two to be used for words by the four-way key selected, two page turnings backward that are used to tabulate by center key;

Twoly be used for stroke retrieval by five key groups, pressing the four-way key, to be used for words selected, presses the page turning backward that center key is used to tabulate;

Twoly be used for stroke retrieval by five key groups, long to be used for words by the four-way key selected, the long page turning backward that is used to tabulate by center key.

As a best case study on implementation, button operation to five key groups, above the optional usefulness among six kinds of schemes first kind just will be pressed and grow by the key mode as two kinds of appointments: by to the pressing of five buttons in the five key groups, realize the stroke search operaqtion; By the length of four-way key in the five key groups is pressed, realize the selected operation of words; By the length of center key in the five key groups is pressed, realize the page turn over operation backward of tabulation.

In the best case study on implementation that the foregoing invention people thinks, in the time of also can be with the selected operation of words to the length of four-way key by change into two during by, the page turn over operation backward that will tabulate to the length of center key by change into pair by, so just, formed the preferable case study on implementation of another one, it is among top six kinds of schemes second kind.

Here former and later two different case study on implementation, when only being different from the page turning backward of the selected and tabulation of words, to the length of five key groups by or two key mode of pressing on, and these two kinds of different key modes respectively have weak point:

In the former scheme, because of having used " long by " operation of button, when stroke retrieve, the maximal value of the duration when five buttons are pressed in the five key groups had been made condition restriction (not too much, otherwise can be regarded as long by operating); During the page turning backward of and tabulation selected at words, then need again the operator by the bond distance on time to the patient visual wait of screen reaction.

In latter's scheme, because of having used " two by " operation of button, when stroke retrieve, the minimum value in the time interval during to the identical stroke code of continuous input position had been made condition restriction (must not be too small, otherwise can be regarded as two by operating); During the page turning backward of and tabulation selected, then need the operator again two the pressing continuously fast same button on time of button at words.

When the stroke search operaqtion, should constitute according to the stroke coding of the individual character that will import or word, specific keys mode by five buttons in the five key groups, import five kinds of stroke coding positions of horizontal, vertical, left, points, discount in its stroke coding formation respectively successively, and satisfying under the precondition of one-to-one relationship, these five stroke coding units distribution mode on five buttons in five key groups is arbitrarily.According to aforementioned best case study on implementation, the specific keys mode of five buttons in the five key groups is referred to press here.In addition, five stroke codings unit in the word coding method and the one-to-one relationship between five buttons in the five key groups, as an example, can show as particularly: horizontal stroke-go up key, perpendicular stroke-following key, cast aside stroke-left button, put stroke-right button, roll over stroke-middle key, this corresponding relation such as Fig. 4 represent.In this corresponding relation, be easy to associate stroke type with its corresponding form of a stroke or a combination of strokes tendency and its representative by the position of each button in whole five key groups, this can provide the hint help of usefulness to the operator, even will each stroke type be printed on the respective keys in the five key groups.

Stroke search operaqtion to above-mentioned illustrates as follows:

The complete stroke coding of individual character " state " is defined as " 25112141 ", and the formation sequence of promptly complete stroke code position is " perpendicular folding horizontal stroke is horizontal anyhow horizontal ", and then its complete key list entries corresponds to " going up upper right on down up and down ";

The complete stroke coding of word " motherland " is defined as " 45-25112141 ", and the formation sequence of promptly complete stroke code position is " some folding-perpendicular folding horizontal stroke is horizontal anyhow horizontal ", then its complete key list entries correspond to " in the right side-under on go up up and down upper right ";

The complete stroke coding that word " is loved one's country " is defined as " 34-45-25112141 ", the formation sequence that is complete stroke code position is " an apostrophe-folding-perpendicular folding horizontal stroke is horizontal anyhow horizontal ", then its complete key list entries correspond to " about-right side in-under on go up up and down upper right ";

The complete stroke coding that word " has ardent love for the motherland " is defined as " 12-34-45-25112141 ", the formation sequence that is complete stroke code position is " anyhow-an apostrophe-folding-perpendicular folding horizontal stroke is horizontal anyhow horizontal ", then its complete key list entries correspond to " up and down-about-right side in-under on go up up and down upper right ".

When the selected operation of words, should be according to the individual character that will import or word position, residing upper and lower, left and right in prepare word tabulation current page, by the corresponding button in position, upper and lower, left and right with it in the four-way key, and utilize the specific keys mode of this button, with target individual character or the selected input of word.According to aforementioned best case study on implementation, here to the specific keys mode of one of four-way key refer to long by.In addition, after a chosen input of prepare word, the prepare word original list also will refresh immediately, and the prepare word in the page after refreshing is generally association's words of an input words.

Individual character no matter, or word, in the process of its stroke retrieval, there is no need under normal conditions their whole stroke coding is intactly imported, and often in only having keyed in its whole stroke coding after several stroke code positions as prefix part, as the stroke result for retrieval, the words of desire input has just come across among the current homepage of prepare word tabulation, this moment by long by in the four-way key with the corresponding button in this words position, can directly select and import this individual character or word.

In tabulation during page turn over operation, should be according to the needs of searching, by the specific keys mode of center key, to prepare word tabulation carrying out page turning backward to the individual character that will import or word.According to aforementioned best case study on implementation, here to the specific keys mode of center key refer to long by.In addition,, corresponding page turning mark should be arranged on screen display, for example can use character " P " expression corresponding to the page turn over operation backward of this tabulation.

Basic demand to the tabulation page turn over operation is, the arbitrary prepare word that is included among the tabulation of current prepare word all can be by browse displays repeatedly, has a problem that how to be presented at each shown before the page turn over operation of backward tabulating page again here.This problem there are following two kinds of solution routes, can use one of them of the two or simultaneously and use.

The first, the page turn over operation backward to prepare word tabulation shows as unidirectional round-robin form, promptly continues page turning backward under current display page is the situation of last page of prepare word tabulation, with the homepage of show candidate words tabulation again.Under the situation of the page negligible amounts that the prepare word tabulation is comprised, it is practicable searching prepare word by the mode of this unidirectional circulation page turning.

It two is, under the situation of the page turning backward of having carried out prepare word tabulation at least once continuously, can pass through clear key, realizes page turning forward that prepare word tabulates, is the contrary operation of above-mentioned page turning backward.Mode by this page turning is forward searched prepare word, can only be to carry out under the precondition of page turning current the execution backward, but not be subjected to what puzzlement of page quantity in the tabulation of current prepare word.

(4) input process for example

On the screen display of a specific embodiment of the present invention, three elements are arranged: text character editing area, prepare word list area, key input viewing area, as shown in Figure 5.Wherein:

The text character editing area is used to show the current text character of importing, but if its content more at most roll screen show, and, will use a black square to represent at subsequent drawings Chinese version cursor with the current editor position of text cursor videotex;

The prepare word list area is used to show the page of the prepare word tabulation under the current operation status, and one of them of four prepare words in this page will be inserted into the cursor position place of text character editing area after chosen;

Key input viewing area, be used to show the sequence of current all keys of having imported, promptly by the character " ", " Shu ", " Pie ", " Dian ", “ Ya that represent the stroke coding position ", and the character " P " of the page turning backward of expression tabulation, the character string that is constituted.

The composition of three screen displays part that in Fig. 5, provides and between the relative position arrangement, be a kind of for example.Except the prepare word list area, give other two screen display parts here, its purpose only is the needs of subsidiary book patent description.In addition, in the process of Chinese character input, the display position of prepare word list area also may not be changeless, if the display screen of electronic message unit is bigger, the prepare word original list is as the operation interface of Chinese character input so, it can be followed the change of text editing when input cursor position and change, because the floatability of this words inputting interface shows, will be convenient to the sight line of operator in text input process and concentrate.

Illustrate the operating process that words mixes input below, and represent with Fig. 6 A-Fig. 6 K.

Suppose that the Chinese-character text that will import is " input in Chinese of personal digital assistant device ", and use the words separate mode of " move/information/terminal// input in Chinese ".Under the initial state shown in Fig. 6 A, at first, according to the one-to-one relationship between five buttons in the five key groups and five the stroke coding units, press five buttons, (complete stroke coding is: 31-115453 to import each stroke coding position that word " moves " successively, complete accordingly therewith key sequence is: upper left-in the right side left side in going up), stroke code position of every input, the prepare word original list just once shows and refreshes, after having imported its preceding 7 stroke code positions, word " moves " among the current homepage that appears at the prepare word tabulation, and be arranged in the upper/lower positions of original list, shown in Fig. 6 B, this moment is by long selected this word of key of pressing, shown in Fig. 6 C; Then, (complete stroke coding is: 32-3251114544 to import each stroke coding position of word " information " in the same way successively, complete accordingly therewith key sequence is: go up in the right side right in lower-left-lower-left), after having imported its preceding 5 stroke code positions, word " information " appears among the current homepage of prepare word tabulation, and is arranged in the last position of original list, shown in Fig. 6 D, select this word by long by last key this moment, shown in Fig. 6 E; Then, since occurred in the current homepage of prepare word tabulation association's word " terminal " of the word of importing " information ", so there is no need to have carried out the stroke search operaqtion this moment, and can directly select this word by its pairing right button, shown in Fig. 6 F by long; Continue, similarly directly by long by last key import individual character " ", shown in Fig. 6 G; At last, (complete stroke coding is: 25-41-15-34 to import each stroke coding position of word " input in Chinese " successively, complete accordingly therewith key sequence is: down-upper right-in going up-about), after having imported its preceding 6 stroke code positions, word " input in Chinese " appears among the current homepage of prepare word tabulation, and is arranged in the last position of original list, shown in Fig. 6 H, this moment, by selected this word of last key, shown in Fig. 6 I, text input was so far all finished by long.

On the basis of state shown in Fig. 6 I, if carry out the page turning backward of twice tabulation continuously, promptly successively length is pressed middle key twice, then its priority process is shown in Fig. 6 J and Fig. 6 K, they have shown two follow-up pages in the prepare word tabulation respectively, and have incrementally added page turning symbol " P " successively in key input viewing area.If on basis shown in Fig. 6 K, carry out the page turning forward of twice tabulation more continuously, promptly successively operate clear key twice, then its priority process is shown in Fig. 6 J and Fig. 6 I, they have then shown previous two pages shown, that be positioned at head in the prepare word tabulation respectively again, and have deleted page turning symbol " P " successively degressively in key input viewing area.What demonstrate is the forward and backward page turn over operation to tabulating under the situation that does not have the input of stroke code position herein, equally also can carry out this forward and backward page turn over operation at any time in the process of stroke retrieval.

(4) about the further feature of input scheme

(1) state of prepare word tabulation resets

Under the original state of prepare word tabulation, words option wherein constitutes, and is the whole character library of this input method and the complete or collected works of dictionary, and the current screen homepage of show candidate words tabulation acquiescently only.

In the stroke retrieving of words input, all words in the current prepare word tabulation, all the time be according to the result for retrieval of stroke code string in whole character word stock of having imported, but the stroke code string that ought import is illegal, be do not exist in the input method code book as the coding or the coding prefix words the time, system will remove current all stroke code positions of having imported automatically, and make prepare word tabulation turn back to previous, the original state when not importing any retrieval code position.The original intention of this design proposal is to be convenient to the stroke coding that the operator restarts to import words, and to need not manually to remove in advance all stroke code positions of having imported.To this characteristic for instance, under the original state shown in Fig. 7 A, after three stroke code positions of input " horizontal stroke, point, perpendicular ", in the homepage of prepare word tabulation, shown to meet four prepare words that retrieval requires, shown in Fig. 7 B; After now continuing the 4th stroke code position of input " left-falling stroke " on this basis, because in the whole character word stock of input method, not existing with " horizontal stroke, point, perpendicular, left-falling stroke " is the words of stroke coding or stroke coding prefix, so Shu Ru the 4th stroke code position " left-falling stroke " is illegal here, under the situation that runs into the input of illegal stroke code position, the prepare word tabulation will automatically reset to previous original state shown in Fig. 7 A.After the prepare word tabulation automatically reset, system as prompting, fed back to the operator with the sound.

In the stroke retrieving of words input, though the stroke code string of having imported is legal, but the operator recognizes that it is to belong to keystroke mis-operation for the stroke coding that will import words, can utilize this moment the CLR key to remove current all stroke code positions of having imported with initiatively correcting, and make the prepare word tabulation turn back to previous, the original state when not importing any retrieval code position.If before this CLR key operation of next-door neighbour, carried out the page turn over operation backward of the tabulation of several times, be the continuous page turning identifier " P " of at least one promptly at the last of key input viewing area, the CLR key operation of carrying out this moment will be the page turning forward to tabulation so, and CLR key operation of every execution, with page turning forward once, delete a page turning identifier " P " simultaneously, again the homepage that shows current prepare word tabulation up to screen, be that last character that key is imported in the viewing area no longer is page turning identifier " P ", after this CLR key operation side of Zhi Hanging is the hand-reset to the prepare word tabulation, and the CLR key operation that continues to carry out after the prepare word tabulation resets will be the deletion to text character.To this process for instance, under the original state shown in Fig. 8 A, when four stroke code positions of input and after carrying out the page turn over operation backward of twice tabulation, shown in Fig. 8 B, now begin to carry out continuously the CLR key operation on this basis: at first because of the backward page turning of a last button operation for tabulation, after carrying out the CLR key operation this moment, the prepare word tabulation will be carried out the page turning forward of tabulation, shown in Fig. 8 C; Carry out the CLR key operation once more, the prepare word tabulation will be carried out the page turning forward of tabulation, shown in Fig. 8 D; Continue to carry out the CLR key operation, the prepare word tabulation will reset to the state shown in Fig. 8 E, and this state is identical with the original state shown in previous Fig. 8 A; Still carry out the CLR key operation again, just begin to delete a character before the cursor in the text character editing area, shown in Fig. 8 F.

In front, no matter be because of automatically reseting that stroke coding illegally causes, the still hand-reset of carrying out because of keystroke mis-operation, system all will remove whole stroke codes position of having imported, but not last stroke code position of current input.Its design considerations is, the input error of stroke coding, often be not to be that a stroke code position by last input causes, but by the sequence error between current each stroke code position of having imported, be that order of strokes observed in calligraphy mistake causes, need the operator to start anew to re-enter correct stroke coding.

(2) the back moment retrieval that automatically resets is invalid

In the stroke retrieving of words, because the operator is to the stroke formation of related Chinese character and the misunderstanding on the aspects such as stroke order and word coding method rule, perhaps casual once in a while button error, the stroke code position that all might cause input error, and and then cause automatically reseting of prepare word tabulation possibly.This operator of occurring in imports automatically reseting of prepare word tabulation in the process of stroke code position fast, although system can accompany by the sound simultaneously and remind, but for the operator of quick operation push-button, very likely can be because of " inertia " effect, after automatically reseting, tabulation still continues to have imported more one even several stroke codes position unavoidably, therefore before the operator plans to start anew to re-enter correct stroke coding, need primarily the more stroke code position of these follow-up inputs manually to be removed.

In order to overcome the inconvenience that needs manually to remove the stroke code position of follow-up input, in specific embodiments of the invention, can enable the prepare word tabulation invalid function of back moment retrieval that automatically resets, in the i.e. of short duration time period after the prepare word tabulation automatically resets, system is for any stroke code position of being imported by five key groups, and all doing shielding processing just will not any key response.After this section, the function of five key group strokes retrieval can recover normal defined blink.Here defined blink section concrete numerical value, excessive or too small all is inappropriate.

To above-mentioned characteristic for instance, in Fig. 9 A, imported three stroke code positions " horizontal stroke, point, perpendicular ", in the homepage of prepare word tabulation, also shown to meet four prepare words that retrieval requires; After now continuing the 4th stroke code position of input " left-falling stroke " on this basis, because in the whole character word stock of input method, not existing with " horizontal stroke, point, perpendicular, left-falling stroke " is the words of stroke coding or stroke coding prefix, so Shu Ru the 4th stroke code position " left-falling stroke " is illegal here, under the situation that runs into the input of illegal stroke code position, the prepare word tabulation will automatically reset to previous original state, shown in Fig. 9 B.What will say here is, in the extremely of short duration time period after entering Fig. 9 B state by Fig. 9 A condition, it will be invalid carrying out the stroke search operaqtion, and promptly system will all will not receive for the stroke code position of new input.

No longer retrieve when (3) prepare word is a small amount of

In the stroke retrieving of words, continuous input along with increasing stroke code position, the quantity of the prepare word in the prepare word tabulation also will be fewer and feweri, capacity when the no more than one page of its quantity, promptly during four prepare words, for the stroke code position of continuing input, the meaning of its retrieval effect is little, because current prepare word tabulation only comprises a page, wherein may chosen input, no more than four prepare word has all visually been enumerated out, there is no need to continue it has been carried out the stroke search operaqtion, on the contrary also may because of the sign indicating number position imported illegally cause the automatically reseting of prepare word tabulation if continue input stroke code position this moment.

At above-mentioned situation, in specific embodiments of the invention, can enable in the prepare word tabulation the prepare word numbers of poles after a little while, shielding continues the function of the stroke code position of input, promptly the quantity when prepare word is equal to or less than four, even one the time, will be shielded automatically by system for the stroke code position of continuing input, this automatic function of shielding will play the effect of the legitimacy judgement of ignoring the stroke code position of continuing input, to avoid having increased fault-tolerant processing ability in other words to a certain extent as much as possible to the stroke code position because of automatically reseting that the illegal caused prepare word in the stroke code position of more inputs is tabulated.

To above-mentioned characteristic for instance, suppose now will import word " two dimension ", the complete stroke coding of this word constitutes " 11-55132411121 ".In the first seven stroke code position " 11-55132 " of having imported it afterwards, " two dimension " makes one of them as a spot of two prepare words, appears among the current page picture of prepare word tabulation, as shown in figure 10.Under this state, no matter be to continue its legal stroke code position " 4 " of input, still import other any illegal stroke code position " 1 ", " 2 ", " 3 ", " 5 ", system will all will not receive or respond, promptly no matter be utilize upper and lower, left and right, in which button proceed the stroke search operaqtion, as the screen display of program reaction, all will be that to remain original Figure 10 state constant.

(4) shielding of few remote Chinese character of stroke number

In Chinese, deposit the rule trend that is used by high frequency toward a small amount of Chinese character.In the Chinese character base of this input method, the existence of the remote Chinese character that remote Chinese character, especially a small amount of stroke number constitute, the mean value performance of required touch potential in the time of will influencing each Chinese character input.In specific embodiments of the invention, in order to improve the input efficiency of Chinese character, can be with the remote Chinese character of the remote Chinese character in the input method Chinese character base, especially a small amount of stroke number formation, make-up shielding gets up from whole Chinese character base.

The remote Chinese character that is made of a small amount of stroke number, for example but be not defined as: Shu Dian Pie Fu I Yin Ya 亅 Yu Shang Xia Myeon Jiu Ha Qe narrow eyes into a slit Tou Ren Jiong Mi Bing Qian Dao Bao Contraband Jie Si Huan Yin Yan Fu Ji bifurcation Zhuang Tuo Ho Ma Chu Yu Ji Ra Death Wang Where Fan Blade Ya Xun Nian Ran mouth Fan For-additional Kong Jue Jue Http In-particular Cao Chuan one European-allies shoots a retrievable arrow the left alone without help narrow Ba Zhang Bing Buddhist Tao Animatedcollapse of the Ji Ji San Chi Xin Rui Quan Si Lv Chuo Cannibals Chou Ji high Da remainder of Jie Gai Of Hal Hol Qi Si

On the putting in order in prepare word tabulation between each prepare word, following the principle before the words that the words of coupling fully is positioned at prefix matching.So, above-mentioned these constitute the also existence of the Chinese character of remote use by a small amount of stroke number in the input method character library, will make that stroke coding with these Chinese characters serves as that the Chinese character that other high frequency of coding prefix uses is shown by postposition, and cause other high frequency to use the more touch potential of input needs of Chinese character.

Required average key press number of times when reducing the input of each Chinese character, in specific embodiments of the invention, can enable the function of shielding of the remote Chinese character of few stroke number, be about to above-mentioned by a small amount of stroke number constitute, and the Chinese character of remote use from the input method Chinese character base, stash temporarily, also promptly be considered as these Chinese characters and do not exist.But enabling of this function, can cause above-mentioned by a small amount of stroke number constitute, and the drawback that can't import of the Chinese character of remote use, so this function can only the person of being operated as a kind of option, definition property ground uses.

Need to prove that what, the whether remote of Chinese character use that stroke constitutes quantity all are relative concepts, the concrete category of few remote Chinese character of stroke number also can only be gone to define by software in input method character word stock.The Chinese character tabulation that provides previously only is an illustrated example, but not specifically indicating or limiting few remote Chinese character of stroke number.

To above-mentioned characteristic for instance, under the original state shown in Figure 11 A, if close the function of shielding of the remote Chinese character of few stroke number, at input stroke coding string " 25 " is “ Shu Ya " process in; screen display two coupling, that be made of few stroke fully remote Chinese character " Shu " and " Jiong " have successively occurred successively shown in Figure 11 B and Figure 11 C in prepare word tabulation homepage; And under the original state shown in Figure 11 A, if open the function of shielding of few remote Chinese character of stroke number, at input stroke coding string " 25 " is “ Shu Ya " process in; screen display but no longer has aforesaid two remote Chinese characters that are made of few stroke successively shown in Figure 11 D and Figure 11 E in the prepare word tabulation in this process.By comparison diagram 11B and Figure 11 D as can be known, import same retrieval code position " 2 " promptly under the situation of " Shu ", they occurred common prepare word "Yes", " on ", " certainly ", but the former remote candidate " Shu " occurred, the latter occurred candidate commonly used " in "; By comparison diagram 11C and Figure 11 E as can be known, in that to have imported same retrieval code position " 25 " be “ Shu Ya " situation under; they occurred common prepare word " in ", "Yes", " time "; but the former remote candidate " Jiong " occurred, and candidate word " content " commonly used has appearred in the latter.The appearance as early as possible of words commonly used; usually can reduce the required touch potential of words input; in this example; under the original state shown in same Figure 11 A; if the words that the operator will import for " in " or " content "; with respect to the function of shielding of closing the remote Chinese character of few stroke number, behind the function of shielding of opening few remote Chinese character of stroke number, only need stroke retrieval number of times still less.So on the integral body statistics, enabling of the function of shielding of few remote Chinese character of stroke number will improve the input efficiency of Chinese character.

Personal settings when (5) scheme is used

In specific embodiments of the invention, in order to adapt to operator's Chinese character input habit better, can be with some technical characterictics, form with personalizing parameters shows, promptly in software is realized, by the use preference of operator,, customize out the Chinese character input mode that meets own use habit by the selection of function menu or filling in of form data according to the individual.List several projects below as an example, can implement one or more.

One of, in specific embodiments of the invention, press operation for the length of five key groups, the numerical value definition of the lasting duration that its button is pressed need vary with each individual.Because under the too small situation of the numerical value of this lasting duration definition, the subjective operation of thinking by mistake of pressing of operator institute is easily grown by operation by actual objectively being identified as of system; And under the excessive situation of the numerical value definition of this lasting duration, need the operator again in the patient visual wait of program being reacted on time by the bond distance.Therefore, this duration numerical value should be defined voluntarily by the operator.In addition, operate for two the pressing of five key groups, its same button also need be varied with each individual by the definition of the numerical value in the double time interval of pressing.Because the numerical value at this interval duration defines under the too small situation, the operator tends to some difficulty in reality is carried out; And at this at interval under the excessive situation of the numerical value definition of duration, when importing same stroke code position continuously same button adjacent pressed operation for twice easily by system identification two by operation for to this key.

Two, in specific embodiments of the invention, in the formation definition of the complete stroke coding of word, the fixed number value that is positioned at top stroke coding position that institute intercepted separately during the complete stroke coding of each non-ending Chinese character in the word constituted, in the integer range that is specified in 1-4, it also can carry out the concrete numerical value definition in personalization ground, the custom preference when importing to adapt to its word search by the operator in this data area.In the formation definition of the stroke coding of word, so-called " fix " quantitative value just emphasizes each non-ending Chinese character is intercepted the identity property or the appointment property of stroke code bit quantity, but and does not mean that the unalterable property of this quantitative value.

Three, in specific embodiments of the invention,, the personalized switch option of open and close is set for its application for the automatically reset function of state of prepare word tabulation.

Four, in specific embodiments of the invention, the invalid function of moment retrieval after tabulation automatically resets for prepare word, by the operator carry out defining personalizedly tabulation automatically reset the back retrieval invalid, promptly do not receive the time period length numerical value of new stroke code position, when this time period length numerical value is zero, represent closing of this function.

Five, in specific embodiments of the invention, the function of no longer retrieving when a small amount of for prepare word, except being provided with for its application the personalized switch option of open and close, also will be when the legitimacy of ignoring the stroke code position of continuing input be judged, quantitative range to prepare word in the current prepare word tabulation defines, and for example is only 1, or within 4.

Six, in specific embodiments of the invention,, the personalized switch option of open and close is set for its application for the function of the shielding of few remote Chinese character of stroke number.

In above-mentioned project, the selection of concrete parameter normally cuts both ways, but its final purpose is still in order to satisfy operator's personal needs.

(6) locating and displaying of special prepare word

For four shown in prepare word original list words, its position arrangement, except the distribution characteristics of the relative position that satisfies upper and lower, left and right,, also should follow following two principle for special prepare word wherein:

In the operating process of stroke retrieval, continuous input along with the stroke code position, screen display refreshes though the prepare word original list is also carrying out constantly, but for the same prepare word that occurs continuously in the input process of sign indicating number position, in the prepare word original list on the display position of upper and lower, left and right, should remain unchanged, promptly the position that occurs continuously its next time is consistent with the position that occurred its last time.The purpose of this mentality of designing is, avoid the display position of same prepare word to change the discomfort that visually may cause the operator, alleviate the burden of man-machine interaction to a certain extent, otherwise, the frequent change of same prepare word on diverse location can increase the tired degree of vision that the operator searches prepare word.For instance, on the basis of state shown in Figure 12 A, input stroke coding string " 431 " promptly the process of " Dian Pie one " successively shown in Figure 12 B, Figure 12 C, Figure 12 D, for the same prepare word that occurs continuously among the figure " ", " road ", " about ", they have remained in this process respectively, and it is upper and lower, the unchangeability of right position.

After a chosen input of prepare word, the prepare word tabulation refreshes immediately, in the screen display after it refreshes, its four follow-up association words normally, among these four follow-up association words, import the display position of words logotype frequency with a last forerunner for next maximum follow-up association words, should be with current to have imported words display position of upper and lower, left and right when the selected input consistent.The purpose of this mentality of designing is by specifying the display position of chosen input probability for maximum next follow-up association words, to move with the position of reducing operator's finger as far as possible.For instance, in Figure 13 A, imported several stroke code positions, front of " people " words successively, make it to come across the current page of prepare word tabulation, this moment candidate's individual character " people " residing position be the four directions to last position, select the last key that also will use when importing this word in the four-way key.After the chosen input of " people " word, suppose that association's words, its occurrence frequency as " people " word are " family " word for a maximum follow-up words, be somebody's turn to do the display position of " family " word in the prepare word original list so, with respect to its position of forerunner's word " people " when selecting input, should be consistent, promptly still be in the last position that upper and lower, left and right show, when selecting input " family " word, also will similarly use the last key in the four-way key, shown in Figure 13 B.

(7) use of two of navigation key kinds of functions

If five key groups among the present invention are embodied in five navigation key on the keypad, five navigation key will be used to the whole words input process that stroke is retrieved, page turning is backward selected, tabulated to words so, this character input function of five navigation key will move (four-way key), option with its traditional cursor and confirm that functions such as (center key) takes place to conflict mutually.For this reason, in the process of text editing input, five navigation key need be carried out mutual state and be switched between character input function of newly giving and the former conventional defined function that has, realize the function that they are different respectively under two kinds of different functional statuses; Or under with a kind of state, realize two kinds of functions of five navigation key independently simultaneously.List four kinds of implementation methods below, in specific embodiment, can only use wherein a kind of, also can use wherein several simultaneously.

Method one: utilize certain button outside five navigation key, directly switch mutually between two kinds of functional statuses with five navigation key, one of them of the soft key that this button that is used for that state switches can be a keypad, * key, # key.

Under the text input state,, can with the function of five navigation key, between character input function and conventional defined function, carry out mutual state and switch by these idle soft keys are carried out by key definition so fully if there is available soft key resource.Except using soft key, can also be by the * key on the standard numeric keyboard, perhaps the # key realizes that this state switches.Distinctive mark between the residing two kinds of functional statuses of five navigation key is whether tabulate as the prepare word of Chinese character inputting interface is presented on the screen.That is to say that under the situation that shows the prepare word tabulation on the screen, five navigation key are used to the feature operation of Chinese character input, otherwise be used to the feature operation of conventional definition.

For instance, use the method press the * key, the function of five navigation key is switched between Chinese character input state and conventional definition status mutually, and with the sign as the current functional status of living in of five navigation key of whether manifesting of prepare word tabulation.Under state shown in Figure 14 A, press the * key, screen will be shown as state shown in Figure 14 B; When pressing the * key once more, screen display is a state shown in Figure 14 A with switchback.Under state shown in Figure 14 A, five navigation key can be carried out the feature operation of Chinese character input; And under state shown in Figure 14 B, five navigation key can be carried out the feature operation of conventional definition, for example cursor can be moved to reposition by the four-way key this moment, shown in Figure 14 C; On the basis of state shown in Figure 14 C, can import Chinese character again after pressing the * key, shown in Figure 14 D, and the words that imported this moment will be inserted into new text cursor part.

This state handover scheme, mode of operation is fairly simple, and this blocked operation can carry out under two states at any time.But this state switching method requirement must exist the button resources of such free time under the text input state, this in other words state switching method need take other button resources.Therefore, in the conceptual design that this state switches, need to investigate above-mentioned button in advance and whether be used to other functional definition.

Method two: utilize certain button outside five navigation key, between input method of Chinese character state of the present invention and other certain character entry method state, switch mutually, and under other certain character entry method state, realize the feature operation of the routine definition of five navigation key, one of them of the soft key that this button that is used for that state switches can be a keypad, * key, # key.

Can set up a kind of hot key between input method of Chinese character state of the present invention and other certain character entry method state gets in touch, this hot key, it can be soft key, also can be * key or # key, by it, between input method of Chinese character of the present invention and other certain character entry method, directly carry out mutual state and switch.For example, when five navigation key are in input method of Chinese character state of the present invention, and the cursor that need to utilize wherein four-way key to carry out upper and lower, left and right in the character text of being imported is when moving or utilize center key wherein that the character text of being imported is finished when confirming, can pass through this hot key, earlier input method of Chinese character state of the present invention is switched to other certain character entry method state, and then carry out the needed conventional feature operation that defines, and switch back to input method of Chinese character state of the present invention again afterwards.

This hot key switches the functional status that not only is used to change five navigation key, can also change the type or the method for character input provisionally.But no matter to making demands before this switching hot key be, be input method of Chinese character state of the present invention, or other certain character entry method state, and in their button operation process, this hot key must be not to be used to other functional definition.

Method three: utilize the third key mode that is different from two kinds of related key modes of words input, between two kinds of functional statuses of five navigation key, switch mutually to center key.

In front about press, long by, two by three kinds of key modes in, can be by center key being used the third key mode that is different from two kinds of related key modes of words input, also promptly use the third key value of center key, realize the mutual switching between two kinds of functional statuses of five navigation key.For example, press and grow by the method for five navigation key and imports words, can switch mutually by the two kind functional statuses of two methods by center key so five navigation key if use; Press and two methods input words if use, can switch mutually by the two kind functional statuses of long method by center key so five navigation key by five navigation key.When five navigation key were switched between two kinds of functional statuses mutually, the distinctive mark between its residing two kinds of functional status was whether tabulate as the prepare word of Chinese character inputting interface is presented on the screen.

This blocked operation can carry out under two states at any time, and because the execution of this state handover scheme does not relate to other button outside five navigation key, therefore it can be implemented under the situation that thumb do not leave five buttons, directly switch the functional status of five navigation key, it is more convenient to operate.But here can be because of using the third key mode of center key, and increased the complexity of operation.

Method four: utilize the third key mode that is different from two kinds of related key modes of words input, in the words input, realize the former conventional defined function that has of five navigation key to five navigation key.

In front about press, long by, two by three kinds of key modes in, can be by five navigation key being used the third key mode that is different from two kinds of related key modes of words input, also promptly use the third key value of five navigation key, in the words input, realize the conventional defined function of five navigation key.For example, if use is pressed and grown by the method for five navigation key and import words, can realize its conventional defined function by two methods so by five navigation key; Press and two method input words if use, can realize its conventional defined function by long method so by five navigation key by five navigation key.

In aforesaid method one, two, three, use two states to realize two kinds of functions of five navigation key respectively, that is: under the Chinese character input state, upper and lower, left and right, in five buttons all be used for the Chinese character input; Under conventional definition status, the four-way key of upper and lower, left and right is used for cursor and moves, the feature operation that center key is used for other definition for example the text input finish affirmation etc.And in current approach four, by being different from the third key mode of two kinds of related key modes of words input, realize the conventional defined function of five navigation key, and the feature operation of this conventional definition in the words input process can be carried out at any time.Therefore different with aforementioned three kinds of methods, in fact the 4th kind of method here do not relate to the mutual switching problem of two kinds of functional statuses of five navigation key, but under a kind of state, the side by side character input function of round Realization five navigation key and conventional defined function.

For instance, might as well suppose to use such scheme: press five buttons and carry out the stroke retrieval; Length is carried out words by the four-way key and is selected long page turning backward of tabulating by center key; Two feature operations of carrying out conventional definition by five buttons.So on the basis of state shown in same Figure 15 A: if pressing key then imports stroke code position " ", shown in Figure 15 B; If it is long by the then selected candidate's individual character " I " of last key, shown in Figure 15 C; Then move delegation on the text cursor as if two by last key, shown in Figure 15 D.

When using two kinds of functions of five navigation key at the same time,, do not relate to other button except that five navigation key, so it is more convenient equally to operate because this method does not relate to the mutual switching of two kinds of functional statuses yet.But because it has used three kinds of key modes of five navigation key simultaneously, the operation easier in the time of will increasing the text editing input like this.
