Description

METHOD FOR HANDWRITING ON THE TOUCHSCREEN [0002]

The present invention relates to a handwriting input method using a touch screen, and more particularly, to a method for expanding a handwriting area on a touch screen and correcting written contents on an extended area.

Recently, devices including touch screens such as smart phones and tablet PCs are increasing in number, and technologies for determining necessary memos by using a finger or a stylus pen are widely used in a device including a touch screen.

In general, the size of the touch screen of a portable device is considerably small even if a stylus pen is used for taking notes. In addition, when handwriting on a touch screen is difficult to write elaborately, it is common to write letters larger than the size of the characters displayed on the touch screen. Therefore, it is difficult to make a handwriting due to space limitation when handwriting with a large size on a small touch screen screen.

Also, since the size of handwritten characters is generally larger than that displayed on the screen, there is a problem that it is difficult to efficiently display written handwritings.

Therefore, there is an increasing need to develop a method for utilizing the handwriting input area as a more effective method for handwriting on the touch screen screen.

1 is a schematic diagram of a control system for inputting a handwriting on a touch screen in accordance with an embodiment of the present invention.

The touch screen device 100 according to an embodiment of the present invention refers to an electronic device having a function of inputting a handwriting on a touch screen. The touch screen device 100, which can input handwriting on the touch screen, may include devices such as a smart phone, a tablet computer, and the like, and may include a desktop PC, a notebook computer PC, etc., and is not limited to any particular device if it includes a touch screen.

The touch screen 110 is a display device for displaying an image, and can display a video signal transmitted by the control unit. A user interface for controlling the touch screen device 100 may be displayed on the touch screen 110. A user may input a signal to the touch screen device 100 through a touch screen without a separate input device in order to control the touch screen device 100. That is, the touch screen 110 plays a role of a display unit and an input unit of the touch screen device 100.

The expansion button 130 is a button for the user to arbitrarily expand the basic handwriting area 120. [ If a larger handwriting area is required when the user hands the handwriting area to the basic handwriting area 120, the handwriting area needs to be expanded. When the user selects the extension button 130 using the finger or the stylus pen, the basic handwriting area 120 can obtain the effect of extending the basic handwriting area 120 regardless of other signals on the touch screen 110 have. Thus, the user can extend the basic handwriting area as needed.

The threshold line 140 measures the shortage of the handwriting area in the basic handwriting area 120 by one line input of the user. For example, when a user continues inputting a single line beyond a threshold line in a single-line input process in the horizontal direction, the threshold line may be a reference line for determining the extension of the basic region. Therefore, the basic handwriting area can be extended without receiving a separate extension command from the user.

The user interface described with reference to FIG. 1 is an exemplary one, and the present invention can be implemented through another type of user interface. In this case, the same effect can be obtained through a simple input process.

2 is a flow diagram of a method for inputting a handwriting on a touch screen in accordance with an embodiment of the present invention. Will be described with reference to Fig. 1 for convenience of explanation.

A method for inputting a handwriting on a touch screen according to the present invention is disclosed as being requested to expand a basic handwriting area (S210).

The electronic document may be displayed on the touch screen 110 of the touch screen device 100 and a memo function capable of inputting a handwriting to the electronic document may be executed. When the memo function is executed, the user can input content through handwriting on the touch screen (110). When the memo function is executed and the user handwrites the touch screen 110, the basic handwriting area 120, which is a space for handwriting due to the limited size of the touch screen, For some reason, the user may make a request to extend the default handwriting area 120. Such a request may be made by a separate input of the user, such as selecting a certain expansion button 130 by the user or making a long tab on the screen.

When the handwriting is input through the critical line 140 while the handwriting is input in the direction of progressing the input of one line when the user inputs one line, it is determined that the extension request of the basic handwriting area 120 is received . That is, the extension request of the basic handwriting area 120 can be received in the handwriting direction even if handwriting is performed in various directions such as left to right, right to left, top to bottom, and bottom to top.

When the extended command is received, the basic handwriting area is expanded (S220).

The extension area 150 is located on the same layer as the basic handwriting area 120 and may have a layer separate from the electronic document. If there is a request for extension of the basic handwriting area 120 in the direction of handwriting, an additional input space is generated in a direction of handwriting. For example, if the handwriting is being input in the left-to-right direction of the touch screen 110, an effect of adding an extended area to the right of the basic handwriting area 120 occurs. That is, if the size of the basic handwriting area 120 is 300 x 600, the extended handwriting area after the extended area may be, for example, 600 x 600, The handwritable area is expanded.

At the same time, an effect of scrolling the extended handwriting area is generated so that continuous input is possible (S230).

When the extended area is generated, the handwriting input input in the basic handwriting area 110 is processed as if it is moved in the opposite direction as handwriting is performed by giving a scroll effect. Therefore, the same effect as scrolling the extended handwriting area in the direction opposite to the direction in which the handwriting is input occurs. The effect of scrolling such an extended handwriting area is that the primary handwriting area 120 is not displayed on the touch screen 110 and the effect of being displayed on the extended area 150 touch screen 110 .

However, if one-line input is continued in the extended area 150 and the handwriting area is insufficient, the handwriting area 120 is requested to be expanded again (S210). Therefore, when the input of one line is continued, the handwriting area is further extended.

Then, when the one-line input is terminated, the one-line input content is displayed on the electronic document in the basic handwriting area 120 and corrected to be displayed on one screen of the touch screen 110 (S240).

When the handwriting area is continuously expanded in one direction, it is not possible to display all the one line input contents on one screen of the touch screen 110. [ Accordingly, the one-line input content is corrected so that the one-line input content can be displayed on one screen on the touch screen 110. For example, if the size of the basic handwriting area 120 is 300 x 600, the size of the extended handwriting area after the handwriting area is extended is 600 x 600, 600, the line input contents can be reduced to 1/2. The corrected one-line input content is displayed on one screen on the touch screen 110. [

In the method of inputting a handwriting on the touch screen 110 according to an embodiment of the present invention, the handwriting area is extended from the basic handwriting area 120 to the extended handwriting area to enable handwriting in a wider area . In addition, one-line input can be continuously performed by processing the screen in the extended handwriting area by the effect of scrolling in the direction opposite to the handwriting direction. In addition, the generated one-line input contents are corrected and displayed on a single screen, so that one-line input contents can be read comfortably. As described above, according to the embodiment of the present invention, there is an effect that a handwritten memo can be created more efficiently and a memo can be confirmed more efficiently.

FIGS. 3A and 3C are schematic diagrams for explaining an example in which an area for inputting a handwriting according to an embodiment of the present invention is extended and a handwriting handwritten in the extended area is corrected.

Referring to FIG. 3A, an electronic document 310 is displayed on a touch screen 110 of a touch screen device 100. The electronic document 310 can be memorized by handwriting input. As the first memo 320 is created in the basic handwriting area 120, the handwriting enabled area is gradually reduced. When the handwriting input is inputted within the critical line 330 of the basic handwriting area 120, the basic handwriting area 120 is extended.

Referring to FIG. 3B, the basic handwriting area 120 extends into the extended handwriting area 350. Also, as the extended handwriting area 350 is displayed, the existing basic handwriting area 120 scrolls to the left of the display, so that it is not visible on the touch screen.

Referring to FIG. 3C, one line of input content 340 is displayed on the touch screen 110 as a corrected content 360. The correction ratio can be reduced by keeping the aspect ratio constant. The reduction ratio is set such that the single line input content 340 can be corrected to the content 360 corrected to fit the touch screen 110. [ And may be displayed on the touch screen 110 after being corrected to a desired size by the user.

4A and 4B are schematic diagrams for illustrating an exemplary embodiment in which handwriting handwritten in an extended area according to an embodiment of the present invention is corrected.

4A, the extended handwriting area 450 is scrolled to the left so that a portion of the left hand input content 430, which is a single-line input content 430 plus a single-line input 420 added to the first handwriting 410, And is not displayed on the screen 110. When the user hands the handwriting on the touch screen 110, the first handwriting 410 and the additional input line input 420 may not be created in parallel. In addition, the end of the first handwriting 410 and the additional input line input 420 may not be continuously connected. The area of the first handwriting 410 may not be displayed on the touch screen 110 when writing handwriting. Therefore, it may happen that the parallelism can not be made and the connection with the end can not be made.

Referring to FIG. 4B, one line of input content 430 is displayed on the touch screen 110 as a corrected content 440. In the present embodiment, the correction corrects the size of handwritten characters. In addition, the calibrated content 440 may be displayed on the touch screen 110 in parallel with a single line. Also, the line input contents 430 may be connected and displayed so as to be displayed without being continuously connected to the end of the first handwriting 410.

When the user hands the handwriting on the touch screen 110, the first handwriting 410 is not displayed on the screen by scrolling when the handwriting is written, so that the one-line input content 430 is continuously generated in parallel The problem of difficulty can be solved. That is, even if the one-line input contents 430 are not parallel and the continuity is broken, the corrected contents 440 can be generated in parallel and maintained in continuity.

5A and 5B are schematic diagrams for illustrating an exemplary embodiment in which handwriting handwritten in an extended area according to an embodiment of the present invention is corrected.

5A, the extended handwriting area may be scrolled to the left so that a portion of the left one-line input content 520 may not be displayed on the touch screen 110 in addition to the first handwriting input. 5A, it is assumed that the size of the text 510 of the electronic document is the font 10 and the average font size of the single-line input content 520 is 30. At this time, The size and the size of the single-line input contents 520 may be different.

Referring to FIG. 5B, the one-line input content 520 may be displayed as a corrected content 530 by being corrected to a size 10 corresponding to the touch screen 110. FIG. In this embodiment, the correction can correct the size of handwritten text. It is possible to measure the average font size of the single line input content 520 and to measure the average font size of the text 510 of the electronic document. It is possible to display the corrected content 530 by correcting the size of the one-line input content 520 so that the font size of the single-line input content 520 becomes the average font size of the font 510 of the electronic document.

In the method of inputting the handwriting on the touch screen 110 according to the embodiment of the present invention, the font size of the one-line input content 520 is converted into the font size of the electronic document font 510 530, it is possible to read the corrected content 530 more easily.

6A and 6B are schematic diagrams for illustrating an example in which an handwriting handwritten in an extended area according to an embodiment of the present invention is corrected.

Referring to FIG. 6A, the extended handwriting area is scrolled to the left so that a portion of the left hand input content 650 may not be displayed on the touch screen 110. However, in the present embodiment, the size of the first handwriting 620 and the additional one-line input 630 and 640 may be different from each other, or may be made nonparallel. In addition, the end of the first handwriting 620 and the additional one-line input 630 and 640 may not be connected to each other. The first handwriting 620 is not displayed on the touch screen 110 when writing handwriting. Therefore, one-line inputs 630 and 640 can be created in which the parallelism can not be achieved and the connection can not be made with the terminal, and the size of the handwriting is different.

Referring to FIG. 6B, one line of input content 650 is displayed on the touch screen 110 as a corrected content 660. In the present embodiment, the correction corrects the size of handwritten characters. In addition, the entire calibrated and corrected contents 660 can be displayed on the touch screen 110 in a single line in parallel. In addition, even if the additional one-line input 630 or 640 is not connected to the end of the first handwriting 620, the one-line input contents 650 can be corrected to be connected and displayed. Also, the size of the one-line input 630 or 640 may be corrected to be the same as that of the first handwriting 620.
