Description
Technical field
The present invention relates to electronic device field, particularly electronic device information input technology field specifically is meant the method that realizes the handwritten stroke input on a kind of touch-screen.
Background technology
In the modern life, along with the continuous development of integrated circuit technique, mobile phone, PDA, navigating instrument etc. various touch-screen electronic equipments have appearred, for example.These touch-screen electronic equipments can be finished increasing user function.For example, receiving and dispatching mail, read Edit Document, surf the web etc.Constantly perfect along with function, these electronic equipments begin to become more and more important instrument in people's life.Yet how quickly and efficiently input text has become a very big challenge on these equipment.
For input in Chinese, this challenge is particularly evident.Because the repetition rate of coding of most of Chinese character coding input method is all than higher, for example phonetic input and stroke input etc.The user also needs page turning just can find corresponding candidate many times after having imported coding, has reduced input speed.And for the low input method of some repetition rates of coding, the Five-stroke Method etc. for example, the user tends to forget the coding of certain word or speech, therefore needs a kind of auxiliary method to help the screening Chinese character.
Summary of the invention
The invention provides a kind of method that realizes handwritten stroke that is applicable on touch-screen, this method can be with the stroke of handwriting mode input character successively, and pairing candidate word is presented on the screen.Simultaneously, this method can combine with other input methods such as phonetics.For example, allow user's input Pinyin earlier, when repeated code or a plurality of candidate word occurring, filter by stroke again.Effective like this page turning number of times that reduced has significantly improved input efficiency.Experiment showed, that this method can improve the Chinese character input speed on touch-screen effectively, and easy to learn.
Compare traditional stroke input, the advantage of this handwritten stroke is to need not extra button support, and more intuitively convenient.The tradition stroke input method need have corresponding stroke button on hardware keyboards, perhaps show several dummy keyboard buttons on touch-screen, and each button is represented a kind of stroke.The user imports strokes sequence by the order click keys.But handwritten stroke need not to reserve button, and the user can be directly in any appointed area of screen, or even whole handwritten strokes on the screen, has saved the keyboard space.The user also need not to adapt to the key position of stroke.
When combining with phonetic, this method realized passes through the number of times that function that handwritten stroke filters candidate word fast can significantly reduce user's page turning in the candidate word tabulation.Experiment shows, the user is at following simplicity initial consonant that needs the input phrase of most of situation, and then with the first sum of picture of each word of handwritten stroke input phrase, can import phrase fast, and input speed is had raising at full speed.In addition, when the user forgets the pronunciation of certain word, need not to switch to other input patterns, directly handwritten stroke gets final product input characters.
According to an aspect of the present invention, provide a kind of method of on touch-screen, importing and filtering Chinese character, comprised, and generated the 1st step of candidate (speech) tabulation with any one input mode input characters except that handwritten stroke with handwritten stroke; On touch-screen, detect the 2nd step that move the user contact; Detected one-time continuous contact moved resolve to a stroke, and add the 3rd step of the strokes sequence of having imported; Finding out the strokes sequence institute that imported from the described candidate that has generated (speech) tabulation may corresponding candidate (speech), forms the 4th step that new candidate (speech) is tabulated.

Embodiment
Before describing in detail according to embodiments of the invention, what should be noted that is that described embodiment mainly is the method step relevant with input text in electronic equipment and the combination of apparatus assembly.Therefore, corresponding device assembly and method step have showed by ordinary symbol in the accompanying drawings in position, and only show the details relevant, in order to avoid because of saying that for having benefited from those of ordinary skills of the present invention conspicuous those details have blured present disclosure with understanding embodiments of the invention.
In this article, such as a left side and right, upper and lower, preceding and after, first and second and so on relational terms only is used for distinguishing an entity or action and another entity or action, and not necessarily requires or hint this relation of any reality between this entity or the action or in proper order.Term " comprises ", " comprising " or any other variant are intended to contain comprising of nonexcludability, make thus and comprise that process, method, article or the equipment of a series of key elements not only comprise these key elements, but also comprise other key elements of clearly not listing, perhaps be the intrinsic key element of this process, method, article or equipment.
Embodiment one
With reference to Figure 1A, this Figure illustrates one and be applicable to portable electric appts 100 of the present invention, it is furnished with touch-screen.Comprise user input area 101 on the touch-screen, show the zone 103 of having imported strokes sequence, the zone 104 of show candidate word (speech).At first, the user presses lower contact (with finger or felt pen) and laterally moves the back and decontrol in zone 101, and its track is 110.Track can be displayed on the screen, also can not be shown.
After the user decontroled the contact, system this time imported pairing stroke for horizontal by detecting the track of contact, can judging.In the present embodiment, being divided into is horizontal, vertical, left-falling stroke, point (or right-falling stroke), five kinds of strokes of folding.The method of judging stroke has a lot.For example, analyze the starting point of track and terminal point with and the track that experienced: if when its track and straight line between 2 differ greatly (variance of distance is bigger), can be judged as " folding "; Otherwise, can judge other four kinds of strokes by the relative position relation of judging starting point and terminal point coordinate, for example, can be judged as horizontal stroke when the horizontal ordinate difference of starting point and terminal point coordinate during much larger than the ordinate difference; When horizontal ordinate difference during, can be judged as perpendicular much smaller than the ordinate difference; When starting point is positioned at the upper right corner of terminal point, can be judged as left-falling stroke; When starting point is positioned at the upper left corner of terminal point, can be judged as a little or presses down.It is worthy of note that this only is a kind of concrete grammar of realizing judging handwritten stroke.No matter use which kind of method, can't change essence of the present invention.
Figure 1B has described the screen content after the user decontrols the contact.Having imported and having demonstrated the stroke of having imported in the stroke sequence area 103 is " horizontal stroke ", shows the pairing the first sum of horizontal candidate that is depicted as in the candidate zone.
Fig. 1 C has described the screen content the when user continues to import.The user after the zone press lower contact in 101 and is moved, formation track 120.After the user decontroled the contact, this stroke of system identification was " left-falling stroke ", and it is joined imported strokes sequence, upgraded the candidate tabulation simultaneously, find out all with words of " horizontal stroke ", the beginning of " left-fallings stroke " stroke for users' selection.When the user had selected a word in candidate zone 104 after, this word just was imported into the text filed of current cursor place, and simultaneously, strokes sequence zone 104 empties.
In certain embodiments, the user can import phrase fast by head (the one or several) stroke of each word of input.For example, import phrase " once " by input " horizontal stroke ", " point ".In order to distinguish, also can in the middle of the stroke of each word, insert separation key with the stroke input of single word.For example, input " horizontal stroke ", separation key, " point " are imported phrase " once ".
Embodiment two
In the present embodiment, handwritten stroke can be used in combination with the phonetic input.When the phonetic input had the candidate word of a lot of repeated codes, handwritten stroke can be used for filtering fast candidate word.When the user runs into the words of not knowing phonetic, need not to switch input method or interface, can directly write out this words with handwritten stroke.
At first with reference to figure 2A, this Figure illustrates one and use portable electric appts 200 of the present invention, it is furnished with a touch screen.The first half at screen is input text area territory 202, has shown a soft keyboard 201 in screen the latter half.In the present embodiment, soft keyboard 201 is a singly-bound Qwerty layout, and each button is represented a letter.The user is by clicking each the button input Pinyin on the touch-screen.What deserves to be mentioned is, in other embodiments of the invention, also can adopt other keyboard layouts, as 9 key layouts of conventional mobile phone, or biliteral key Qwerty layout etc.Concrete keyboard layout has nothing to do with method described in the invention.
In order to keep the needs of the clear of synoptic diagram and explanation, this paper will come each button on the unique identification figure with letter shown on each button.For example, identify the key in the upper left corner on the soft keyboard with key " q ".
At first, the user puts keystroke " y " on soft keyboard, " o ", " u " input Pinyin " you ".Shown in Fig. 2 A, listed the candidate of phonetic in the candidate word tabulation 204 for the limit priority of " you ": " having ", " again ", " by ", " friend ", " right side " etc.The word " excellent " that the user finds to want to import is not in tabulation.
Then, the user filters candidate with handwritten stroke.With reference to figure 2B, the user is 205 with the track of hand or felt pen current collector process on soft keyboard zone 201.This track is judged as stroke " left-falling stroke ", therefore in stroke filtration zone 203 " Pie " is added strokes sequence.Demonstrate phonetic in the candidate word zone 204 and be " you ", the candidate of the first sum of being depicted as " left-falling stroke ".The user selects " excellent " from the candidate word tabulation, it is inputed to text filed.
In some cases, the user may forget the pronunciation of certain word under spelling mode.In the present embodiment, the user need not to switch to other input patterns, can directly import Chinese character with handwritten stroke on the keyboard area of spelling mode.This mode is similar to embodiment one described handwritten stroke mode, and just the keyboard area of spelling mode becomes user input area, in order to accepting handwritten stroke, and the user need not switch mode promptly can phonetic or the mode of stroke mix input characters.
In certain embodiments, when the user imported phrase by the phonetic mode, the user can filter phrase by the first sum of picture of each word in the input phrase, also can filter by the stroke of first word in the input phrase.For example, after the user had imported phonetic " shi shi ", candidate word had " fact ", " enforcement ", " in real time ", " having a try ", " in good time ", " constantly ", " affairs of human life ", " unfounded " etc.The user further once imports handwritten stroke " left-falling stroke ", " point " with the handwritten stroke filtering function on screen, then candidate word is filtered into " unfounded ", since the first sum of being depicted as " left-falling stroke " of " mistake ", the first sum of being depicted as of " reality " " point ".And if the filtration stroke of user's input is " horizontal stroke ", " erecting ", then candidate word is filtered into " fact ", " affairs of human life " etc., because the beginning stroke of these two first words of candidate word is " horizontal stroke ", " erecting ".
Change other input methods (as Two bors d's oeuveres, the Five-stroke Method etc.) into if it should be noted that the phonetic input in the present embodiment, the handwritten stroke filtering function is still effective, does not influence essence of the present invention.
Fig. 3 has described the method 300 of filtering the input Chinese character on a kind of touch-screen involved in the present invention with handwritten stroke, comprises following steps: with any one input mode input characters except that handwritten stroke, and generate candidate (speech) tabulation (step 301); On touch-screen, detect the user contact and move (step 302); Detected one-time continuous contact moved resolve to a stroke, and add the strokes sequence of having imported (step 303); Finding out the strokes sequence institute that imported from the described candidate that has generated (speech) tabulation may corresponding candidate (speech), forms new candidate (speech) tabulate (step 304).
For step 301, wherein any one input mode except that handwritten stroke can comprise phonetic input (comprising spelling or Two bors d's oeuveres), the Five-stroke Method, phonetic notation, Cangjie, input methods such as short-term training.
For step 303, move described contact can resolvedly be five kinds of strokes: horizontal, vertical, point or press down, cast aside, folding.
