Description
Technical field
The present invention relates to electronic device field, particularly electronic device information input technology field, specifically refers to a kind of method that realizes handwritten stroke input on touch-screen.
Background technology
In the modern life, along with the development of integrated circuit technique, various touch-screen electronic equipments are there are, such as mobile phone, PDA, navigating instrument etc.These touch-screen electronic equipments can complete increasing user function.For example, receiving and dispatching mail, read Edit Document, surf the web etc.Constantly perfect along with function, these electronic equipments start to become more and more important instrument in people's life.But how quickly and efficiently input text has become a very large 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 higher, such as Pinyin Input and stroke input etc.User also needs page turning just can find many times corresponding candidate word having inputted after coding, has reduced input speed.And for the low input method of some repetition rates of coding, such as the Five-stroke Method etc., user tends to forget the coding of certain word or word, therefore needs a kind of auxiliary method to help screening Chinese character.
Summary of the invention
The invention provides a kind of method that is applicable to realize handwritten stroke on touch-screen, the method can be with the stroke of handwriting mode successively input character, and corresponding candidate word is presented on screen.Meanwhile, the method can combine with other input methods such as phonetics.For example, first allow user's input Pinyin, in the time there is repeated code or multiple candidate word, then filter by stroke.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 the input of traditional stroke, the advantage of this handwritten stroke is without extra button support, and more intuitively convenient.Tradition stroke input method need to have corresponding stroke button in hardware keyboards, or is touching several dummy keyboard buttons of screen display, and each button represents a kind of stroke.User carrys out entering stroke sequence by order click keys.But handwritten stroke is without reserved button, user can be directly in any appointed area of screen, or even whole handwritten strokes on screen, has saved keyboard space.User is also without the key position that adapts to stroke.
When in the time that phonetic is combined, the function of handwritten stroke fast filtering candidate word that what this method realized pass through can significantly reduce the number of times of user's page turning in candidate word list.Experiment shows, user only need to input the simplicity initial consonant of phrase in most cases, and then by the first stroke of each word of handwritten stroke input phrase, can input fast phrase, and input speed is had to raising at full speed.In addition,, in the time that user forgets the pronunciation of certain word, without being switched 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 inputting and filtering Chinese character on touch-screen with handwritten stroke, comprised input mode input characters except handwritten stroke with any one, and generate the 1st step of candidate word (word) list; On touch-screen, detect the 2nd step that move user contact; The one-time continuous contact detecting is moved and resolved to a stroke, and add the 3rd step of the strokes sequence of having inputted; From the described candidate word having generated (word) list, find out the strokes sequence inputted may be corresponding candidate word (word), form the 4th step of new candidate word (word) list.
According to an aspect of the present invention, provide a kind of method of inputting and filtering Chinese character on touch-screen with handwritten stroke, comprised the following steps:
1) on screen, show user input area;
2) on touch-screen, detecting user contact moves;
3) the one-time continuous contact detecting is moved and resolved to a stroke, and add the strokes sequence of having inputted;
4) remove the track that in user input area, move contact;

Embodiment
Describing in detail according to before embodiments of the invention, should be noted that, described embodiment is mainly 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 with understanding embodiments of the invention, so as not to because of for have benefited from those of ordinary skill in the art of the present invention say apparent those details fuzzy present disclosure.
In this article, such as left and right, upper and lower, front and rear, first and second and so on relational terms is only used for distinguishing an entity or action and another entity or action, and not necessarily requires or imply this relation of any reality between this entity or action or sequentially.Term " comprises ", " comprising " or any other variant are intended to contain comprising of nonexcludability, the process, method, article or the equipment that make thus to comprise a series of key elements not only comprise these key elements, but also comprise other key elements of clearly not listing, or be the intrinsic key element of this process, method, article or equipment.
Embodiment mono-
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.On touch-screen, comprise user input area 101, show the region 103 of entering stroke sequence, the region 104 of show candidate word (word).First, user is by decontroling after lower contact (with finger or felt pen) transverse shifting in region 101, and its track is 110.Track can be displayed on screen, also can not be shown.
When user decontrols behind contact, system is by detecting the track of contact, and it is horizontal can judging this time corresponding stroke of input.In the present embodiment, be divided into horizontal, vertical, left, points (or right-falling stroke), five kinds of strokes of folding.The method that judges stroke has a lot.For example, analyze the starting point of track and terminal with and the track that experienced: if when its track and the straight line between 2 differ greatly (variance of distance is larger), can be judged as "fold"; Otherwise, by judging that the relative position relation of starting point and terminal point coordinate can judge other four kinds of strokes, for example, when the horizontal ordinate difference of starting point and terminal point coordinate is during much larger than ordinate difference, can be judged as horizontal stroke; When horizontal ordinate difference is during much smaller than ordinate difference, can be judged as perpendicular; In the time that starting point is positioned at the upper right corner of terminal, can be judged as slash; In the time that starting point is positioned at the upper left corner of terminal, can be judged as a little or presses down.It is worthy of note, this is only a kind of concrete grammar that judges handwritten stroke of realizing.No matter use which kind of method, can't change essence of the present invention.
Figure 1B has described user and has decontroled the screen content behind contact.In entering stroke sequence area 103, having demonstrated the stroke of having inputted is " horizontal stroke ", shows the corresponding the first sum of horizontal candidate word that is depicted as in candidate word region.
Fig. 1 C has described screen content when user continues to input.User presses after lower contact movement in region 101, forms track 120.When user decontrols behind contact, this stroke of system identification is " slash ", and is joined entering stroke sequence, upgrades candidate word list simultaneously, finds out all words with " horizontal stroke ", the beginning of " slash " stroke and selects for user.When user has selected after a word in candidate word region 104, this word is just imported into the text filed of current cursor place, and meanwhile, strokes sequence region 104 empties.
In certain embodiments, user can input phrase fast by head (the one or several) stroke of the each word of input.For example, input phrase " once " by input " horizontal stroke ", " point ".In order to distinguish with the stroke input of single character, also can in the middle of the stroke of each word, insert separation key.For example, input " horizontal stroke ", separation key, " point " are inputted phrase " once ".
Embodiment bis-
In the present embodiment, handwritten stroke can be combined with Pinyin Input.In the time that Pinyin Input has the candidate word of a lot of repeated codes, handwritten stroke can be used for fast filtering candidate word.In the time that user runs into the words of not knowing phonetic, without switching input method or interface, can directly write out this words with handwritten stroke.
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.Be territory, input text area 202 in the first half of screen, shown a soft keyboard 201 in screen the latter half.In the present embodiment, soft keyboard 201 is singly-bound Qwerty layout, and each button represents a letter.Each key-press input phonetic that user is shielded by point touching.It is worth mentioning that, 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 schematic diagram and explanation, the each button on unique identification figure will be carried out with letter shown on each button herein.For example, identify the key in the upper left corner on soft keyboard with key " q ".
First, user puts keystroke " y " on soft keyboard, " o ", " u " input Pinyin " you ".As shown in Figure 2 A, in candidate word list 204, listed the candidate word of the limit priority that phonetic is " you ": " having ", " again ", " by ", " friend ", " right side " etc.User finds that the word " excellent " of thinking input is not in list.
Then, user filters candidate word with handwritten stroke.With reference to figure 2B, user is 205 with the track of hand or felt pen current collector process on soft keyboard region 201.This track is judged as stroke " slash ", therefore in stroke filtration zone 203, " Pie " is added to strokes sequence.In candidate word region 204, demonstrate phonetic for " you ", the candidate word of the first sum of being depicted as " slash ".User selects " excellent " from candidate word list, is inputed to text filed.
In some cases, user may forget the pronunciation of certain word under spelling mode.In the present embodiment, user, without being switched to other input patterns, can directly input Chinese character with handwritten stroke on the keyboard area of spelling mode.This mode is similar to the described handwritten stroke mode of embodiment mono-, and just the keyboard area of spelling mode becomes user input area, in order to accept handwritten stroke, and user can phonetic without switch mode or the mode of stroke mix input characters.
In certain embodiments, in the time that user inputs phrase by phonetic mode, user can filter phrase by the first stroke of each word in input phrase, also can filter by the stroke of first character in input phrase.For example, when user has inputted after phonetic " shi shi ", candidate word has " fact ", " enforcement ", " in real time ", " having a try ", " in good time ", " constantly ", " affairs of human life ", " unfounded " etc.User further once inputs handwritten stroke " slash ", " point " on screen with handwritten stroke filtering function, candidate word is filtered into " unfounded ", since the first sum of being depicted as " slash " of " mistake ", the first sum of being depicted as " point " of " reality ".And if the filtration stroke of user's input is " horizontal stroke ", " erecting ", candidate word is filtered into " fact ", " affairs of human life " etc., because the beginning stroke of these two candidate word first characters is " horizontal stroke ", " erecting ".
If it should be noted that the Pinyin Input in the present embodiment changes other input methods (as Two bors d's oeuveres, the Five-stroke Method etc.) into, handwritten stroke filtering function is still effective, does not affect essence of the present invention.
Fig. 3 has described the method 300 of filtering input Chinese character on a kind of touch-screen involved in the present invention with handwritten stroke, comprise following steps: the input mode input characters with any one except handwritten stroke, and generate candidate word (word) list (step 301); On touch-screen, detect user contact and move (step 302); The one-time continuous contact detecting is moved and resolved to a stroke, and add the strokes sequence (step 303) of having inputted; From the described candidate word having generated (word) list, find out the strokes sequence inputted may be corresponding candidate word (word), form new candidate word (word) list (step 304).
For step 301, wherein any one input mode except handwritten stroke can comprise Pinyin Input (comprising spelling or Two bors d's oeuveres), the Five-stroke Method, phonetic notation, Cangjie, the input methods such as short-term training.
For step 303, described contact is moved and can be resolved is five kinds of strokes: horizontal, vertical, point or right-falling stroke, skim, folding.
