Description
Technical field
The present invention relates to computerized information input processing technology field, particularly relate to a kind of method and system that is used for the hand-written quick input on the electronic equipment.
Background technology
In recent years, along with the use of hand-written electric equipment is more and more universal, for example PDA (personal digital assistant), mobile phone, HPC (Hand Personal Computer) etc., it is more and more important that the hand-writing input method that arises at the historic moment with it also becomes.Though it is the input method kind in these electronic equipments is very many in the market,, also more and more higher to the requirement of hand-writing input method along with people need import and the increasing of process information amount.
Hand-writing input method on the present market in the various electronic equipments, generally need the user on the hand input device (as touch-screen) of equipment, to write each character in regular turn, just can identify corresponding individual character, word or short sentence, the most basic this handwriting input mode, its maximum defective is that recognition speed is slow, after user writing is finished, input method needs the pause in several seconds just can provide recognition result, in addition because hand-writing input method also relates to the problem of recognition accuracy, so the user also needs to spend the extra time and goes to correct mistakes; Therefore, this type of common handwriting input mode, its efficiency ratio is lower.
In order to improve the input efficiency of hand-writing input method, prior art has also proposed some solutions, for example, the Chinese patent publication number is that the patent document of CN1372182 discloses a kind of quick hand-writing input method, this input method mainly is the simple identification (as stroke or special symbol) that the user is write on a handwriting device, and appearance (as name, phrase or phrase or the like) within importing identifying, change and be stored on the storage device automatically; When this handwriting device is intercepted the user and is imported this sign once more, this sign and the sign that has been stored in this storage device can be compared, as conform to, then will identify the real content output that is replaced, so, can reach and use less stroke or certain special symbol, input the purpose of name, phrase, long sentence or password fast.
Under situation about having, the person's handwriting of user's handwriting input can also be used to call the corresponding function order, for example, the Chinese patent publication number is that the patent document of CN101118471A discloses a kind of system that utilizes self-defined hand-written symbol to carry out function, this system comprises: at least one hand-written symbol registering unit is used for the function of self-defining hand-written symbol of registered user and the user appointment corresponding with this symbol; With at least one hand-written symbol recognition unit, be used to read the hand-written symbol of user's input, and discern according to the user-defined hand-written symbol of hand-written symbol that reads and the registration of described hand-written symbol registering unit; With a performance element, be used for if the unanimity as a result of above-mentioned identification, the then corresponding function of registered hand-written symbol in startup and the described hand-written symbol registering unit.By this system, the user can be according to custom and the hobby of oneself, and oneself definition hand-written symbol and function that itself and oneself are often used are associated.
Above-mentioned solution allows the user that some information that need import (as long sentence, phrase etc.) or the order that need call, function etc. are defined as some simple identification (or symbol), the user is when these contents of input like this, only need write its corresponding identification, input method can be identified as it corresponding long sentence or corresponding command functions.Though this quick input mode accurately, fast, but because its sign that allows to use generally all is simple stroke or special symbol, when the user had defined too much sign or do not used this user-defined identification for a long time, the user was easy to forget or obscure the content of this sign representative.Secondly, the sign that sets as the user and common language comparatively near the time because handwriting tracks is more random, system is difficult to definite user and wishes identification character or the common language imported therefore, can have the identification error between identification character and the common language.
In a word, need the urgent technical matters that solves of those skilled in the art to be exactly: how can the creationary solution that proposes the hand-written quick input of another kind, can allow user's handwriting input fast, easily obtain required content, and reduce the memory burden of user identification character.

Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The present invention can describe in the general context of the computer executable instructions of being carried out by computing machine, for example program module.Usually, program module can comprise the routine carrying out particular task or realize particular abstract, program, object, assembly, data structure or the like.
The invention belongs to a kind of special quick hand-writing input method, its core idea be with some long sentences, special symbol or command function pre-defined simple for some, be convenient to character or the entry (hereinafter referred to as identification character) remembering and manage; When the user prepares to import these long sentences (or special symbol, command function etc.) once more, only need its corresponding simple characters of handwriting input, and the handwriting input triggered mark (as, draw an outside and surround line); During identification, the character script that system then points to this triggered mark is searched comparison as identification character presetting mapping table, as conforms to, then with replacement (or order) output of this identification character correspondence.So, can reach, to realize importing in batches the purpose of long sentence (or special symbol, particular command etc.) by the less character of handwriting input.
With reference to Fig. 1, show the method preferred embodiment of a kind of hand-written quick input of the present invention, can may further comprise the steps:
Step 101, reception user's handwriting information.
Step 102, judge whether described handwriting information comprises the preset trigger mark;
Step 103 is if then discern at described triggered mark handwriting information pointed;
Triggered mark of the present invention can be set according to actual conditions by those skilled in the art, for example, adopts underscore, double underline or the like, as long as can be convenient to identification.Handwriting input for spoken and written languages such as English, triggered mark such as underscore or double underline is to be suitable for fully, but handwriting input for spoken and written languages such as Chinese, because this triggered mark might be mixed mutually with some stroke of literal, so the present invention proposes a more preferred embodiment.
In the preferred embodiment, described preset trigger is labeled as an outside of finishing and surrounds line, the person's handwriting of handwriting information for being surrounded by this encirclement line that described triggered mark is pointed.Concrete step 102 and 103 can be transformed to: judge whether described handwriting information comprises that an outside of finishing surrounds line; If then discern at the person's handwriting that is surrounded by this encirclement line.
Whether the present invention does not need qualification to surround line accurately closed, also do not need to limit the concrete shape of surrounding line, needs only in fact to have the characteristic of surrounding.For example, described encirclement line can also can be rectangle or triangle or the like for the curve of circular, oval or similar circle.
Certainly, surround line if do not comprise an outside of finishing in the handwriting information that is received, what illustrate then that the user imports is not sign, but common language information gets final product so directly carry out the identification of common person's handwriting.But in fact, the present invention also is indifferent to: when not comprising an outside encirclement line of finishing in the handwriting information, specifically how to carry out follow-up flow process; For example, can directly finish.
Step 104, according to this recognition result, from described preset mapping table, obtain and this recognition result bulk information corresponding; Described mapping table is used to store each identification character and corresponding bulk information thereof.
Step 105, export described bulk information.
Bulk information described in the present embodiment can comprise long sentence, long word, phrase or special symbol or the like, and described bulk information to the text editing district of step 105 transmission at this moment gets final product.
In another preferred embodiment of the present invention, described bulk information also can be various command functions, as, enter a new line, delete, copy, paste, duplicate, shearing etc.; Perhaps start certain application program, carry out computing function or the like.Certainly, in this embodiment, step 105 just need be sent to the corresponding interface with described bulk information, to carry out the corresponding function order.
In a word, the present invention does not need to limit the concrete form of bulk information, substitutes corresponding bulk information as long as the user thinks by identification character, can improve the input efficiency of oneself, and then the user just can self-defined required identification character and corresponding bulk information thereof.
In addition, need to prove that the present invention does not need to limit the concrete form of identification character yet, described identification character is as long as in the character set scope that recognition engine can be discerned; If the user remembers for convenience, also can adopt the mode of abbreviation, as, identification character " Chinese king " correspondence " Hanwang Technology Co., Ltd " or the like.Described abbreviation can belong to the same-language literal with corresponding bulk information, also can be different spoken and written languages, as, identification character " Chinese king " correspondence " Hanwang Technology Co, Ltd. " etc., the former is a Chinese, the latter is English full name.
Preferably, in order to satisfy the management of user to data in the mapping table, embodiment shown in Figure 1 can also comprise following preferred steps: the user-defined identification character and the corresponding bulk information thereof that receive user's input; In mapping table, upgrade or add a data recording.By the management of User Defined mode, can obtain personalized mapping table, to satisfy user's individual demand at the active user.
The triggered mark that adopts the outside to surround line in the preferred embodiment of the present invention can better be adapted to various spoken and written languages, and relatively is fit to people's use habit.Because for the triggered mark of types such as underscore, identification is got up than being easier to, and the identification of surrounding line for outside difficulty relatively is that example is elaborated so all adopts outside encirclement line in the following examples.
The present invention can judge whether described handwriting information comprises that an outside of finishing surrounds line, simply introduces it below by several concrete examples by various feasible modes.Those skilled in the art can adopt suitable scheme according to actual needs and experience.
Example 1
Referring to Fig. 2, this example can be finished in the following manner to surrounding the judgement of line:
The coordinate extreme value of step 204, a more above-mentioned specific track and other stroke track; If the X coordinate extreme value of described other stroke track is all between the X of described specific track coordinate maximum value and minimal value, the Y coordinate extreme value of described other stroke track all between the Y of described specific track coordinate maximum value and minimal value, determines that then a described specific track is that the outside surrounds line.
With reference to Fig. 3, show the coordinate synoptic diagram when relatively determining to surround line.Adopt X among Fig. 3
Fir_left, X
Fir_right, Y
Fir_top, Y
Fir_bottomX coordinate minimal value and the maximum value of representing the first stroke track respectively, Y coordinate maximum value and minimal value; X
Other_left, X
Other_right, Y
Other_top, Y
Other_bottomX coordinate minimal value and the maximum value of representing other stroke track respectively, Y coordinate maximum value and minimal value.
If set input rule be: write the encirclement line earlier, write identification character again; Then, this example can only judge whether the first stroke track is that outside encirclement line gets final product.If set input rule be: write identification character earlier, write the encirclement line again; Then, this example can only judge whether the finishing touch track is that outside encirclement line gets final product.
Because what user's input habit was general is exactly above-mentioned two kinds, if so under the situation of not setting input rule, can judge earlier whether the first stroke track is that the outside surrounds line, judge again whether the finishing touch track is that the outside surrounds line, to satisfy most of user's input habit.Certainly, the present invention does not need to limit concrete priority judgement order; Preferably, can determine by statistics user's input habit, as, suppose to write the encirclement line after most of user gets used to, judge earlier then whether the finishing touch track is that the outside surrounds line, to raise the efficiency.
Example 2
This example can be finished in the following manner to surrounding the judgement of line:
Obtain the first stroke track in the described handwriting information;
Obtain the X coordinate maximum value and the minimal value of described the first stroke track, Y coordinate maximum value and minimal value;
Obtain the X coordinate maximum value and the minimal value of other stroke track, Y coordinate maximum value and minimal value;
The coordinate extreme value of more above-mentioned the first stroke track and other stroke track;
If the X coordinate extreme value of described other stroke track is all between the X of described the first stroke track coordinate maximum value and minimal value, the Y coordinate extreme value of described other stroke track is all between the Y of described the first stroke track coordinate maximum value and minimal value, determine that then described the first stroke track is that the outside surrounds line, finishes to judge;
Otherwise, continue to obtain the next record track, repeat above-mentioned determining step, up to the judgement of finishing the finishing touch track, finish.
Example 2 is for example 1, and the key distinction is one by one stroke track to be judged.Because it need all judge that so its efficient is lower, but it can satisfy user's various input habits, does not need to set input rule to each stroke track, improve user's experience.
Example 3
This example can be finished in the following manner to surrounding the judgement of line: the curve regions of obtaining the first stroke track or finishing touch track is (if not closed; can virtual closure); whether statistics has the coordinate points of other stroke track to drop on outside the above-mentioned zone then; if no, determine that then this first stroke track or finishing touch track are for surrounding line.
Provide a specific embodiment below, the present invention is further illustrated.
In advance " Hanwang Technology Co., Ltd " is defined as identification character " Chinese king ", like this when the user needs often to import such long sentence under the text editing state, only need on hand input device, to write " Chinese king ", and draw one and surround line, encase " Chinese king " (being designated hereinafter simply as the zone circle character) (referring to accompanying drawing 4A); When system detect surround line after, its character identification result " Chinese king " can be inquired about in mapping table as identification character, and be converted to " Hanwang Technology Co., Ltd " and be sent to text editing district (referring to accompanying drawing 4B).Do not surround line (referring to accompanying drawing 4C) if when handwriting input, draw, then directly its recognition result " Chinese king " is sent to text editing district (referring to accompanying drawing 4D).
Its concrete internal technology implementation procedure can be divided into following three parts: the management of the identification of zone circle character, the transmission of recognition result and identification character.
(1) identification of zone circle character (referring to Fig. 5)
Because the character script that the user writes is made up of some strokes, and described envelope curve is one maximum in the person's handwriting, and this curve may be the first stroke in the person's handwriting, also may be the finishing touch in the person's handwriting.Therefore when whether the character script obtained in judgement of present embodiment is besieged, can adopt any or combination in following two kinds of situations to judge:
Situation (1)
If drawing earlier, the user surrounds line, written character then extracts four extreme points (Xfir_left, Xfir_right, Yfir_top, Yfir_bottom) of the first stroke track in the person's handwriting and four extreme points (Xother_left, Xother_right, Yother_top, Yother_bottom) that all the other stroke track distribute respectively again.In the present embodiment, they are respectively: the going up point most, descend point most of this stroke track, the most left point, the rightest point.If four extreme points of all the other stroke track satisfy: Xfir_left＜Xother_left, Xfir_right＞Xother_right, Yfir_top＞Yother_top, Yfir_bottom＜Yother_bottom illustrates that then the character script of writing is besieged.Dismiss the first stroke stroke data in the person's handwriting, character script can be separated from the curve that surrounds and be used as identification character and discern.
Situation (2)
If user elder generation written character, the back is drawn and is surrounded line, then extracts four extreme points (Xlast_left, Xlast_right, Ylast_top, Ylast_bottom) of finishing touch track in the person's handwriting and four extreme points (Xother_left, Xother_right, Yother_top, Yother_bottom) of all the other stroke track respectively.Similar with the decision criteria of situation (1), if Xlast_left＜Xother_left, Xlast_right＞Xother_right, Ylast_top＞Yother_top, Ylast_bottom＜Yother_bottom illustrates that then the character script of writing is besieged.Dismiss finishing touch stroke data in the person's handwriting, character script can be separated from the curve that surrounds and be used as identification character and discern.
(2) transmission of recognition result
The present invention need do some special processings to recognition result, its processing procedure following (referring to Fig. 6) before sending recognition data to the text editing application program:
The flag data message of the recognition result that step 602, detection are obtained its objective is for distinguishing identifier character and non-identification character.If flag=1 shows that this recognition result belongs to identification character, then change next step over to, further process; Otherwise, belonging to non-identification character (being common character), its recognition result can directly be sent to the text editing zone in the application program;
