Description

Font setting method and system using user's handwriting input {Method And System Using User's Hand-writing Input}

The present invention relates to a method for setting the type and size of a font desired by a user in a software program including various fonts such as a word processor or a graphic tool. More specifically, the present invention relates to a method for allowing a user to set a desired font through a stroke input by a user without having to set a font.

As the number of computer users increased rapidly and computers became larger and faster, some word processors and graphic tools were installed as basic specifications on computers and tablet PCs, and dozens of basic fonts were installed. However, most users only know a few of the fonts they use frequently, what fonts are installed, what they look like, and how big the font is in points. As a result, the task of setting the font was a long time.

Referring to Figure 1, the prior art, a lot of time in the typeface selection and a lot of time is a lot of time to determine what fonts one by one, and in selecting the size of the font is intuitive to the user because of unfamiliar units It was inconvenient because it had a non-interface. To select a font, use only the font combo box to select one of the tens (hundreds) of fonts, set the size in points, confirm the result with the results shown in the preview, or select the font by modifying it again. It was a way to do it. As a result, users have become so accustomed to setting fonts and take time to select them. In addition, it is not easy to determine the size of a font in units of points, which is a standard for computer display devices. After all, after several trials and errors, we set the font. For general word processor users, you may feel this inconvenience, but for those who work with graphics that care about font selection, you may feel more uncomfortable.

In order to solve the above problems, it is an object of the present invention to provide a method that allows the user to set the desired font through the stroke that the user inputs by hand, even if the user does not set the font manually, so that anyone can easily set the font. . Another object of the present invention is to improve the work efficiency by reducing the time taken for the font setting that we usually take for granted. Still another object of the present invention is to make it possible to easily set fonts having special characters such as 'wingdings' that are difficult to find the shape and size of the font. Recently, many new fonts are being developed and the present invention has a greater meaning given the trend that they are being added to the font of the software.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

'Font' as defined in the present invention refers to formatting characters in a particular style and size so that they can be printed or displayed on the screen. The type design of fonts is a change of design fonts. Therefore, it is worth noting that 'Times New Roman' means a typeface, and 'Times New Roman, 10 point' means that it means one 'font'. In addition, in the present invention, the "stroke" refers to the shape of a character input by hitting or hitting using a pen or a tool similar to a pen.

2 is a block diagram showing the structure of a font setting system using a user handwriting input in the present invention. The system recognizes a stroke input unit 210 for reading strokes input manually by a user, a size recognizing unit 220 for recognizing the size of the input stroke, and a character for the stroke input by the user. The character recognition unit 230 to select the type of the font most similar to the recognized stroke and the comparison determination unit 240 to select the size of the point with the highest similarity to the recognized stroke, the user It may be configured as a history storage unit 250 for storing the history information about the font set in the set, and the font setting unit 260 for setting the type of the font and the point size of the font. In addition, the comparison determination unit 240 is a built-in font reading module 241 for reading the font stored in the device, the size adjustment module for adjusting the stroke size to the point size most similar to the size of the recognized stroke And a matching determination module 243 for selecting the type of the font having the highest similarity through one-to-one matching with the recognized characters and the corresponding characters in all the fonts embedded in the apparatus. ) Is a preview presentation module 261 which presents a user with a font corresponding to a result of high similarity in advance before setting the font, and confirms whether to use the font presented in the preview or a predetermined number of fonts presented in the preview. It can be configured as a user selection module 262 to determine which font to use.

3 is a flowchart illustrating a method of setting a font on an application program by a user using handwriting in the present invention. First, a user receives a user input through a process of manually inputting a stroke through the stroke input unit 210 of FIG. 2 (S301). As a next step, the size of the stroke manually input by the user is recognized through the size recognizer 220 (S302). This step is a step in which a font setting system (hereinafter abbreviated as FontRecognizer) using a user's handwriting input recognizes the size of a font in units of points through input strokes. Even if the font size is the same for each font, the actual font size may be slightly different.

As a next step, it is recognized what character is the stroke input by hand through the character recognition unit 230 (FIG. 2) (S303). The process of determining whether the stroke entered by the user using the pen input tool is actually 'A', 'Z', 'ga' or 'I', etc. is required to write only one character by the stroke. There are so many application software for character recognition that users can easily obtain and write. Although any recognition engine may be used, it is easy to use the 'MS Recognize Method' provided by Microsoft as an example in this embodiment. This is a function that Microsoft supports for Tablet PCs. When a user enters a stroke through the pen input device on the Tablet PC, the corresponding recognition result is displayed. For 'MS Recognize Method' the URL 'http://msdn.microsoft.com/library/default.asp?url=

/library/en-us/tpcsdk10/html/inkedit_ref/tbmthrecognize_ed.asp 'for more details.

As a next step, the type of the font having the highest similarity is selected by comparing the characters recognized through the comparison determination unit 240 of FIG. 2 with the corresponding characters in all the fonts embedded in the apparatus (S304). After scaling all the fonts currently stored in the database through the resizing module (241 in FIG. 2) to the size recognized by the FontRecognize, and scaling them through the matching determination module (243 in FIG. 2). The process of selecting a candidate having a high similarity by comparing a character and a stroke input by the user. Various matching algorithms for determining similarity may be possible here, but it is easy to use 'sketch matching' which is commonly used. As an example of how this matching algorithm works, compare 'ㅁ' and 'ㅇ' and compare them pixel by pixel and increment 1 by the sum count only if both are colored for each pixel (AND). Let's do it. After comparing from the upper left to the lower right, the similarity is determined by calculating Sum Count ÷ total number of pixels.

Thereafter, if there is only one font having a similarity higher than a criterion set by the user, the font may be set as the font, but the font is presented through the preview presentation module 261 of FIG. 2 (S310) and the user selection module ( Through step 311 of FIG. 2, the user confirms as a desired font, and may be set to the presented font or may not select the presented font if the result is not desired.

If there are a plurality of candidates having similarity higher than the criteria set by the user, the preview presentation module may display n predetermined fonts determined by the user by referring to the history of the user's font selection stored in the history storage unit 250 of FIG. 2. (2306 of FIG. 2) and the user selects one font from the fonts presented in the preview through the user selection module (262 of FIG. 2) (S307) to the size of the selected font and the type of the font. The process of setting the font is performed (S308).

4 is a flowchart illustrating another method for setting a font on an application program by a user using handwriting in the present invention. First, a process of recognizing the size of the input stroke as a point size using a process of inputting a stroke manually by a user through the stroke input unit 210 of FIG. 2 (S401) and a size recognition unit (220 of FIG. 2). S402 is the same as the step of FIG. 3. However, in the exemplary embodiment of the present invention, there is no character recognition process for recognizing which character is a stroke input by the user. After determining the size of the stroke input by the user through the size recognition unit 220 of FIG. 2 without undergoing the character recognition process (S402), the input stroke and the built-in stroke are installed through the matching determination module (243 of FIG. 2). A method of selecting a character having a high similarity compared to all the characters in all the fonts and selecting the type of the font to which the character belongs (S403). Since the character recognition process is not performed, the process is compared with all the characters of all the fonts, and thus, there is a significant disadvantage in the font setting speed than the process of FIG. 3. However, the present embodiment can be applied to a case where it is difficult to recognize which character through the character recognizer in case of a special character such as 'windings' rather than a general character, and a character input by the character recognizer is desired. This can also be useful in many cases.

Steps after the above steps are the same as in the above-described process of FIG. 3, and thus description thereof will be omitted.

Fig. 5 shows a window as a user interface of FontRecognizer, a software program applied as an embodiment of the present invention. In this figure, the user inputs a stroke using an input device 510, a font combo box 520 displaying a font having the highest similarity with the stroke input by the user, and the size of the stroke input by the user as the point size. A size combo box 530, a color combo box 540 manually set by the user, a preview portion 550 showing the shape of the font having the highest similarity with the stroke input by the user, having the highest similarity A detailed button 560 for viewing a list when there are a plurality of fonts having a predetermined or more similarity including a font, a confirmation button 570 for confirming whether to set a font shown in the preview, and a preview. If the font presented in is not the font desired by the user, it may be composed of a cancel button 580 that does not select the presented font. There.

In the above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical idea of the present invention. It is possible.

According to the present invention, in setting the font, there is an effect that the font and size can be easily set in a user-friendly manner similar to the user's font and intuitively.

According to the present invention, there is a convenient effect in selecting special characters that are difficult to find and input.

In particular, devices such as PDAs (Personal Digital Assistants) and Tablet PCs come with basic pen inputs and most users are familiar with the pen input method, and thus the present invention can be expected to have a greater effect when used in such devices.
