Description of the Invention: [Technical Field 3 of the Invention] Field of the Invention 5 e 10 15 ❹ 20 The present invention generally relates to handwriting input, and more particularly to a touch sensitive display screen with character handwriting capable of detecting handwritten input by a user User interface and electronic handwriting device, and a method for handwriting input. t Prior Art 3 Background of the Invention It is currently common to perform handwriting input using an electronic handwriting device such as a portable/personal assistant (pda), a palmtop computer, and a mobile terminal (e.g., a mobile phone). In particular, handwriting input on mobile terminals has become popular in countries in the Asia Pacific region, especially China. These electronic handwriting devices rely primarily on wheel-in devices such as styluses and touch-sensitive display screens. As is well known to those skilled in the art, the basic process of the handwriting input scheme is that the user writes the character to be input on the touch sensitive display screen using the stylus, and the touch sensitive display screen can detect the handwriting written by the stylus pen. To identify the characters that the user really wants to enter. At present, many companies including Motorola 'Sony_Ericson and Nokia have set up a lot of handwriting input solutions. In terms of the allowed user writing area, the handwriting input scheme generally exists in two forms: a box-based text input method and a full-screen text input method. The frame-based method limits the writing area of the end user to one or more virtual boxes in the touch-sensitive display screen, and the full-screen writing input scheme is free of the limitation of the frame boundary, and the touch-sensitive display screen area is The vast majority are provided for writing. 5 200947309 5 10 15 In terms of the number of characters that can be entered in a single pass, there are roughly two forms of handwritten input schemes: single character rounding and multi-character input. In the single character input method, the character handwriting written by the user at one time is recognized as one character, so the user can only input one character at a time; and in the multi-character rounding method, the user can input multiple characters at a time. A multi-primary handwriting that the user writes in succession at a time can be recognized as a plurality of characters. For the single character input method, it is common practice to provide the user with a character estimate after each input of a word, so the user has to stop the pen and wait for the estimation result after writing each character, and select among the estimation results. Although this method of input is very precise in the identification of the input person, fesi is a way of inputting character by word, and its recognition speed fundamentally satisfies people's electricity demand. Moreover, this does not conform to the writing habits of the average user, because when waiting for a piece of paper after entering the bar on the paper, few users will write each character x when writing, and usually people are always used to continuous Write, for example = see a phrase or a short sentence in units of pause. ..m ^ , multi-character input method is more close to the user's book Gongyu than the single-character input method. However, for the multi-character input method, a problem H is difficult to correctly divide the written multi-character handwriting. As usual, the household. In the process of recognizing the writing strokes of multi-characters, it is necessary to cut the knives into a plurality of components, and divide the divided components into a plurality of groups corresponding to one character, and then in the result of the segmentation Based on the identification of the characters that the user wants to turn into. In general, the segmentation may be based on a gap between a plurality of written _^ factors 或 or a gap between different portions of a single character (e.g., the radicals of the founder). The difficulty of segmentation often lies in the pen 20 200947309 5 〇 ίο

I] If the gap between the pre-element and the gap between the same-character and the pen is the same, the misalignment is caused. This situation is particularly prone to the writing of complex Chinese characters. Therefore, it can be seen that many recognition errors can be avoided if the strokes in the multi-character handwriting can be correctly segmented into a single character. In addition, in the existing multi-character input solution, the lack of human-computer interaction and the lack of user interface design cannot provide an effective method for segmentation error correction, and therefore many users are discouraged by frequent input errors. Moreover, because of the lack of interactive capabilities to correct character segmentation errors, the recognition speed is very slow. Therefore, it is advanced in the art to provide a user interface and electronic input device that allows for more efficient handwriting input, especially multi-child input one.

Various exemplary embodiments. It is to be understood that other embodiments can be used, and structural and functional modifications can be made without departing from the scope of the invention. Explanation of terms Handwriting: indicates the entirety of a character trace written on a touch-sensitive display by an input device such as a stylus. Stroke: A single stroke in a character trace written on a touch-sensitive display by an input device such as a stylus, which is a basic constituent of the character. Component of the handwriting: A portion representing the composition of the handwriting obtained by dividing the handwriting, usually consisting of one or more associated strokes. Segmentation result: indicates that when the handwriting is recognized, the handwriting is divided into one or more components, wherein respective components belonging to each character in the written multi-character can be divided into a group to identify a single character. . The result of this process of dividing the handwriting into components and then grouping the components is the result of the splitting. Q For example: On the touch-sensitive display screen, two characters “female” and “child” are written, indicating that the writing traces of these two characters are handwriting. A total of five strokes are written, and each stroke is a stroke. When identifying, the writing trace may be divided into 20 components to be recognized by the present, so the recognition result may be "good"; the writing trace may also be divided into two components to identify now, so the recognition result may be It is a "woman". It can thus be seen that two different segmentation results result in two different recognition results.

On most of the screen area of the display screen 110, the user can write the characters he or she wants to input or perform command operations by using the input device 12. The touch sensitive display screen 110 according to the present invention can support a multi-character input method, and teaches that a plurality of characters can be written in a plurality of lines of the screen (i.e., support for multi-line writing). Specifically, by using the form of the writing device 120 on the display screen in a manner similar to writing on paper, the touch sensitive display screen 110 can detect that the writing handwriting 'turns it into electronic material and supplies it to the processing device, which is processed by the processing device. The pen is identified. Finally, the identified characters - that is, the characters that the user wants to input - can be input as text information to various applications of the electronic device 100, such as a messaging application (eg, email, SMS, MMS, etc.). , 曰 application, phonebook application, and more. For example, in the example shown in Fig. 1, the finally recognized character "good" is presented on the line indicated by the dot line. 5 Ο 10 15 ❿ 20 In addition, by clicking, tapping or dragging the input device 120 on different areas or window interfaces on the display screen 110, the user can use the stylus 250 as an interactive tool similar to a mouse in a computer. The following operations are used to control the character input of the electronic input device 100, such as selecting within the candidate character list options, setting the position of the cursor on the display screen 110, selecting different control elements (eg, icons or click buttons), etc. . The processing device 130 is coupled to the touch sensitive display screen to identify the written handwriting detected from the touch sensitive display screen, and may also perform corresponding operations in response to an input command input from the input device 12A. In the traditional handwriting input process, when the user writes, the writing handwriting is displayed on the touch-sensitive display screen, but the writing of the writing pen, that is, the writing of the next one or more characters, and the writing of the handwriting will be The processed device is replaced by the character "good," which is obtained by recognizing the obtained word j as indicated by the dotted line in the figure. In this case, the user writes the pen down, I don’t want to check the previous book, Jing Zhan... One reason for the 7L handwriting design is that the rule of the normal job is often limited. After the writing, the touch sensitivity is not only 6 but not the text application. Explicit control window 'for example, (four) word silk _, (four) _, according to the domain function table. The handwriting left by writing often f will occupy most of the job _ curtain (10), such as more than half) or almost the whole, so after writing the pen If still 13 200947309 keeps the handwriting on the touch-sensitive display, it will reduce the writing space, and it may be confused because it overlaps with the text application and the control window. For multi-character input, Write multiple characters at a time, and 5 especially in the case of multi-line writing (ie, multiple characters input at a time are written in different lines on the touch-sensitive display screen), so the handwriting is on the touch-sensitive display screen. The occupied space is larger than the single character input. According to the present invention, a user interface capable of popping up and indenting is provided on the touch sensitive display screen - the handwriting query window 112. The size of the handwriting view window 112 can be compared The touch sensitive display screen 110 is much smaller. When the handwriting view window 112 is popped up (ie, the situation shown in FIG. 1), the handwriting that has just been written is presented on it, but only written on the touch sensitive display screen. Compared to the handwriting, the size of the handwriting displayed by the window 112 is scaled down--because the handwriting view window 112 is smaller than the touch-sensitive display screen 11. When the handwriting view window 15 112 is indented, it can be reduced. As an illustration, on one corner or side of the touch-sensitive display screen 110, the writing space on the touch-sensitive display screen is occupied as little as possible, so that the user can pop up the handwriting when the handwriting needs to be viewed. Look through the window and indent it when you don't need it. Therefore, through the handwriting view window, you can alleviate the space limitation of the touch-sensitive display screen to a certain extent, so that you can check the written words after writing the characters. Handwriting, while not affecting the use of writing space and other window interfaces. In addition, users sometimes inevitably have writing errors that need to be modified, or the recognition errors of the processing device need to be corrected. And, it is possible that the user wishes to modify/correct only One character instead of all the 200947309 characters written. This way, if the user can refer to the written handwriting and correct the handwriting after writing the character once, the recognition of the modified handwriting will be beneficial. Improve the correct rate and recognition speed of handwriting recognition. Therefore, in the step-by-step, on the handwriting window ιΐ2, the user is provided with the function of correcting the handwriting of the η ΛΑ ΛΑ ΛΑ Μ 前 , , . When the handwriting view window 112 is viewed, for example, using the input device 120, it is possible to directly modify the displayed scaled down handwriting on the handwriting view, or to pass through other user interface devices (such as a keyboard). The handwriting performs a modification/repair 10 result, and the post-processing device 13G will recognize and modify the modified/corrected handwriting update, such as directly on the displayed scaled down handwriting, or in addition to the pen to correct the writing. error. As another example, the handwriting segmentation result of the processing device may be corrected, which will be described in detail later with reference to Section 3®. In order to improve the performance of the user interface, a candidate character list area is selected, wherein there are a plurality of candidate characters for the user book to be recognized by the processing device 130. Estimation of the corresponding character of the _ handwriting and/or wording for subsequent possible rounds? prediction. However, the existing user interface, after multi-character recognition, provides a phrase corresponding to the written multi-character handwriting as a recognition result, and no other phrase as a candidate recognition result. Such a meta-discovery identifies a recognition error, and most of them can only view a plurality of candidate characters corresponding to each hand-written word to select the correct one that originally wants to be input.

Computer, etc. Further, in the following (four), the description will use SMS, as an example of the application of the handwriting, but it should be understood that other applications can also be used to implement the technical solution of the present invention. Figure 2a-e illustrates a visual representation of a pop-up and indented handwriting look-up window as needed in accordance with an embodiment of the present invention. As shown in the figure, after the characters ("2&"), the characters are "happier", by clicking (figure) touch-sensitive display screen 16 200947309 5 ❹ 10 15 ❹ 20 110 right arrow 2A, will The handwriting view window 112 can be popped up (Fig. 2c). The window 112 presents a scaled down handwriting of the "hapther" four characters that have just been written. This window can be indented by clicking again (Fig. 2d) arrow 2B (Fig. 2e). It should be understood that the manner in which the control window 112 is ejected and retracted (such as the above-described operation of clicking the arrow 2A/2B) is not a key element of the present invention, and other control methods may be used to control the pop-up and indentation of the window 112, for example, by Keyboard input commands or clicks on the stylus (including clicks, double taps, drags, etc.) to touch other menus or other buttons on the display. Figure 3a-c illustrates an example of how to correct the segmentation result of the handwriting and thus update the recognition result on the handwriting view window. Presented on the handwriting view window 112 as shown in Fig. 3a is the handwriting of the "hapther" four characters that have just been written on the touch sensitive display screen 110. It is assumed that the handwriting can be divided into six components according to the handwriting segmentation function, for example, each component is framed in a virtual frame as shown. It is possible that, due to the "more" strokes in writing and the "forces" in "plus", they are closer together, resulting in the division of "more" and "force" in a group when the handwriting is divided. A similar problem has appeared for the handwriting of "fast," and "le". Thus, the phrase corresponding to the multi-character handwriting estimated by the recognition function is "honor, sputum, and user". The phrase you originally intended to enter does not match at all. As shown in Fig. 3b, the segmented components can be re-grouped by pen gestures using, for example, a stylus. For example, multiple components belonging to the same character can be grouped together by a loop pen gesture as shown. In this example, "force," and "mouth" are grouped together to form the character "plus", and "the same is true for the fast component. Although not shown in the figure, it is possible to use the grouping of '° and no components, that is, those components are divided into that group, so that the re-grouping of the components is more intuitive. . For example, the dashed box in the graph may be changed as the regrouping, so that the components grouped in the same group are grouped in the same virtual box, and the different components are grouped by the dashed box (ie, different Character). After re-sorting, the recognition result is changed from incorrect "lightness" to the correct phrase "more happy", as shown in the 3c circle. Thus, through the handwriting view window, the multi-word can be corrected intuitively and quickly. The segmentation result of the meta-stroke obtains the correct character that the user wants to input. 1〇 It is easy to think that the way to modify the character handwriting is not limited to the form shown in Fig. 3. For example, other pen gestures can also be used. The individual components belonging to the same character are separated, or a certain component is deleted by other operations. The circular pen gesture mentioned here refers to determining the circle by the geometric position of the movement trace on the touch sensitive display screen of the stylus. The operation of selecting the content may be implemented by the prior art. As will be apparent to those skilled in the art, the pen gesture in the above description is not limited to the present invention, and the components may be regrouped or otherwise modified by other operations. As mentioned earlier, the existing multi-character input user interface either recognizes, selects, modifies or deletes the rewriting one by one, or the entire The speech recognition, the selection, the modification or the deletion of the rewriting. Therefore, the multi-character input efficiency is very low. However, the technical solution of the present invention can obtain the recognition result for the entire phrase corresponding to the multi-character handwriting, thereby Obtaining the recognition result for the corresponding single character 'thus both allowing the user to select, modify or delete the entire phrase, and allowing the user to select, modify, delete or insert a single character 18 200947309 rewrite. To illustrate the invention according to the invention These features of the user interface, as shown in the 4a-u diagram, are written by handwriting the Chinese sentence "I wish you all happy and happy". >More 5 ❹ 10 15 ❹ 20 As shown in Figure 4a Write on the touch-sensitive display screen "I wish you all the handwriting." Listening to the peddling (4) Lang, the list of candidate phrases is presented in the candidate window of the candidate window. For example, the candidate phrase = table includes two candidate phrase entries "I wish everyone, and "see everyone". When the second item happens to be the multi-word ship language that the user wants to lose, you can continue the book ^ There is no need to pause (as shown in Figure 4c), at which point the first item "I wish you all, by default, is a positive media phrase, presented as text of the short message content. If the first entry of the candidate phrase list presented in the candidate phrase field 114 is not the correct phrase 'the user wants to enter, and the correct candidate phrase is located elsewhere in the candidate phrase list, then the The correct phrase is selected from the list of candidate phrases. As shown in the 4th_4f picture, after the touch sensitivity is displayed on the screen (4d picture), the next four characters "Happy Chinese New Year," after the handwriting, can be closed as stylus _ human device selection (number _) row The phrase "Happy Chinese New Year" in the second place of the candidate phrase list is presented as text of the short message content (Fig. 4f). If there is no user in the candidate phrase list presented in the candidate phrase block 114, the user wants to input The correct phrase, if it is not a segmentation error, you can first select the option phrase that is basically the same as the correct phrase, and then use the candidate block 116 to select a single correct character or rewrite a single character. This avoids rewriting The trouble of the whole phrase. 19 200947309 10 15 20 g The picture is not, after the three characters "Yuan Lan Festival, ^ W 4g" of the touch-sensitive display screen book, the lower column (10) presents the heart and stomach, you can choose Fine-grained) Candidate Phrase, which is closer to the correct J; 'Silver is not a good short-character that you want to enter. Section, is correct. W includes both two for 7° and the third for short silver. Block the 114 towel, as shown in the figure, you can focus the cursor to In the candidate k column 114, the candidate word column 116 is selected to present the material ''in the word 兀..., above' and then the other candidate characters in the user's original want to turn the person's to the 'none'. Select the correct word = yes. The character "yuan,," so that the candidate can still be the correct one corresponding to the single character in the candidate word block ^, a, .^, and the single character is deleted. To rewrite the '4j-〇 diagram shows this situation.

Yuan "宵", and the child "宵,, inserted in the character "yuan," and "section, between. If there is a segmentation error, the candidate phrase may not have a candidate phrase that is substantially close to the correct idiom at all. Thus, the handwriting view window (1) can be popped up, ^ judged 纟, - see the handwriting segmentation result, and re-draw or other handwriting corrections on the window to obtain the updated as the 4P- As shown in Fig. 4u, select the position to continue writing (Fig. 4p)' and the four characters under the scent-human writing (Fig. 4q) are "happier".

The figure shows a visual view of an example of deleting a single character according to an embodiment of the present invention. As shown in Figure 5(4), three characters are written at one time, "Handwriting, and then, the back button I8 in the candidate window is in the form of ♦". You can delete the three characters by clicking on it. For example, the 5th_ As shown, after the candidate word shot has been subjected to focus selection 15, the back key 118 is in the form of, its function is only valid for the selected single word, and clicking on it deletes the selected single character. The form of the reverse key 118 and the manner of operation (i.e., click) shown therein are merely illustrative, and it is obvious that it can take any other suitable form and operation. 2〇* In the above embodiment, the handwriting is rounded. It is a Chinese character, the writing axis is > flat it and the writing direction is left to right and wraps downwards. However, it should be understood that there are only examples, not limitations of the present invention. The handwriting input can also be English. A letter or other form of character or symbol. The writing axis and the writing direction may also be other, such as vertical, from top to bottom, etc. and the 21 200947309 written characters may also be written separately. Multiple In fact, the attack changes only involve the knowledge of the detected handwriting without affecting the implementation of the technical solution of the present invention. The second formula = can also support the character input method. 5 Figure 6 is according to the present invention. Embodiment of the method of hiding handwriting input # Flowchart. In the step s on the touch-sensitive display on the book letter. 纟Step s2, detecting the handwriting of the characters written on the touch-sensitive display screen. In the step magic, Recognizing the character handwriting. In step S4, popping up the small amount of the hand-sensitive display screen on the touch-sensitive display screen as needed, in the handwriting window, where the handwriting view window is presented The reduced-sized Chinese character handwriting can also be indented to enlarge the writing space. According to the further embodiment of the present invention, if it is necessary to correct/modify the segmentation result of the handwriting, the process Going to step, the segmentation result is corrected on the handwriting view window. The segmentation of the handwriting can be performed in the process of identifying 15 pairs of character handwriting, or can be corrected in response to the need to correct/ In response to the indication of the handwriting, less than Yes, in response to the correction, returning to step S3, updating the recognition of the written character handwriting based on the corrected ❹ segmentation result. If it is not necessary to correct/modify the handwriting segmentation result, then The correct character to be input may be selected from the candidate character order estimated by the recognition process at step 20 S6. According to an embodiment of the present invention further, the identifying step S3 may include estimating the written character pair handwriting, a candidate phrase list corresponding to the multi-character handwriting, and estimating a list of (four) characters corresponding to any one of the candidate short 4 towels in the candidate phrase list. And 22 200947309 5 ❹ 10 15 ❹ 20, a correct phrase can be directly selected from the candidate phrase list (step S61) as an expected input character corresponding to the entire phrase of the multi-sub-note handwriting. The correct character may also be selected from the list of candidate characters corresponding to a single character in the selected candidate phrase (step S62) as the expected input character of the single character. Moreover, the present invention can provide a device corresponding to the method, the device being comprised of various modules that provide the functionality for performing the method. A module may be implemented, in part, as a hardware' partially implemented as software or firmware (combination of software hardware) that may be executed by a processor such as a controller, microprocessor or other computing device. The present invention can be provided as a computer program product comprising a computer readable storage structure on which the computer program code (ie, software or firmware) is embodied for execution by a processor. The above handwriting input scheme, as an enhanced handwriting input method, will improve the usability of mobile phones. In the above and the following contents, the Chinese character input is taken as an example for description, but it should be understood that the present invention can be applied to other types of characters in addition to the Chinese characters, such as other characters. English, Japanese, Sweatshirts) 'Other non-verbal words (such as symbols)' or a combination of the above. In addition, the techniques of the present invention can be applied to other functions of the nuclear handwriting input user interface design, such as = fixed telephone with touch sensitive display, computer, personal digital assistant (pDA). The present invention includes explicit or generalization herein. Any novel feature disclosed or a combination of these features.
