METHOD AND APPARATUS FOR SELECTING TEXT IN POTABLE DEVICE}

The present invention relates to a portable device, and more particularly, to a method and apparatus for selecting text displayed on a portable device through touch input.

Recently, the display device has a large number of touch screen input methods in which a user directly touches a screen using a finger or an electronic pen. Such touch screen input methods are mainly employed in portable terminals such as smartphones, mobile phones, notebook computers, all-in-one PCs, tablet PCs, and portable multimedia players (PMPs).

The touch screen input method may provide a convenient user interface as an input means for inputting location information indicated by the user by touching a specific location of the display screen instead of a keyboard, mouse, or physical button.

For example, when composing a text message on a portable device, the text message can be edited through touch input. That is, when the paragraph corresponding to the text message is displayed, when the user wants to copy a text column consisting of a plurality of texts and insert or delete the text column at another position in the paragraph, the text column can be selected by touch input. have. This is shown in FIG. 1 is a diagram illustrating a case of selecting text using a stylus pen, which is a kind of electronic pen.

Referring to FIG. 1, when the text paragraph is displayed as shown in screen A 10, when the stylus pen 30 points a specific point of the text paragraph for a predetermined time or more, as shown in screen B 20, the pointing point is displayed. The corresponding text string 21 is selected. In general, the unit of text string 21 selected is one word displayed near the pointing point. In order to allow the selected text string 21 to be visually distinguished, the portable device highlights the text string 21 to represent a selection area. Then, a handler 22 is displayed which can expand or collapse the text selection area around the highlighted text string 21, that is, around the selection area.

In the prior art, a type of touch input mainly used as a method for selecting text through touch input is a long press type for maintaining a touch input on a word for a predetermined time. However, the ability to select text and long press touch input are less intuitively related.

In addition, when text is selected through the long press touch input, only one word at the touched point is selected. When a user wants to select a plurality of words, the user selects a specific word through the long press touch input, and a handler around the selected word. If 22 is displayed, it is inconvenient to touch the handler 22 and then move the handler 22 to a desired point.

In order to solve the above problems, the present invention provides an intuitive and easy text selection method and apparatus.

In addition, the present invention provides a method and an apparatus that, when a user selects text and then additionally selects the text, may further select the text in an operation similar to the operation in which the text was previously selected.

Referring to the configuration of the touch screen 190 and the touch screen controller 195 when the first and second methods are implemented in combination, Figure 5 is a touch screen 190 and the touch screen according to an embodiment of the present invention It is a figure which shows the structure of the controller 195.

Referring to FIG. 5, the touch screen 190 includes a display panel 190a, a first touch panel 190b, and a second touch panel 190c. The display panel 190a may be a panel such as an LCD, an AMOLED, etc., and displays various images according to various operation states, application executions, and services of the portable device 100.

The first touch panel 190b is a capacitive touch panel in which a thin metal conductive material (for example, an Indium Tin Oxide (ITO) film, etc.) is coated on both surfaces of the glass to allow current to flow on the glass surface). It is a panel coated with a dielectric that can store charges. When the surface of the first touch panel 190b is touched by an object, a certain amount of charge is moved to a contact position by static electricity, and the first touch panel 190b recognizes the amount of change in the current caused by the movement of the charge and is touched. The location will be detected. Through the first touch panel 190b, all touches capable of generating static electricity can be detected, and touches by a hand touch or a pen can be detected.

The second touch panel 190c is an EMR type touch panel, in which a plurality of loop coils are disposed in a predetermined first direction and a second direction crossing the first direction, respectively, and have an electromagnetic induction coil sensor (not shown). And an electronic signal processor (not shown) for sequentially providing an AC signal having a predetermined frequency to each loop coil of the electromagnetic induction coil sensor. If there is a pen 200 incorporating a resonant circuit near the loop coil of the second touch panel 190c, a magnetic field transmitted from the loop coil generates a current based on mutual electromagnetic induction in the resonant circuit in the pen 200. Let's do it. Based on this current, an induction magnetic field is generated from the coil constituting the resonant circuit in the pen 200, and the second touch panel 190c detects the induction magnetic field in the loop coil in a signal receiving state, thereby allowing the pen to be detected. The approach position or touch position of the 200 is detected. Through the second touch panel 190c, an object capable of generating a current based on electromagnetic induction may sense approach and touch.

The first touch panel controller 195a converts the analog signal received from the first touch panel 190b by hand or pen touch sensing into a digital signal (for example, X, Y, and Z coordinates) and transmits the analog signal to the controller 110. . The second touch panel controller 195b converts the analog signal received by the pen 200 approach or touch sensing from the second touch panel 190c into a digital signal and transmits the analog signal to the controller 110.

 The controller 110 controls the display panel 190a, the first touch panel 190b, and the second touch panel 190c by using digital signals received from the first and second touch panel controllers 195a and 195b. Can be. For example, the controller 110 may display a line corresponding to the touch trajectory on the display panel 190a in response to the approach or touch of the finger or the pen 200. In addition, according to an exemplary embodiment of the present disclosure, when a text selection pattern is input, the controller 110 may highlight the corresponding text string and display the text string on the display panel 190a.

Next, referring to FIGS. 6 to 9, a text selection process using the electronic pen 200 according to an embodiment of the present invention will be described. 6 and 7 illustrate an operation of the portable device 100 for text selection according to an embodiment of the present invention. 8 and 9 illustrate examples of selecting text in a horizontal line pattern according to an embodiment of the present invention.

6 and 7, it is assumed that a text string consisting of at least one text is displayed on the display panel 190a of the portable device 100. The text columns may be arranged in horizontal writing or vertical writing. In the embodiments of FIGS. 6 and 7, it is assumed that the text columns are arranged in horizontal writing. For example, it is assumed that a paragraph of a horizontal writing method is displayed as shown in the first screen 410 of FIG. 8.

6 and 7 assume that the text selection mode is set in the portable apparatus 100. The text selection mode is a mode for detecting a text selection input while at least one text string is displayed. The text selection mode may be set by selecting the relevant menu item. Alternatively, when the touch input is performed while the button 210 of the electronic pen 200 is pressed, the portable device 100 sets the operation mode to the text selection mode.

In addition, when displaying a text string consisting of a plurality of texts on the display panel 190a, the text arrangement information is stored in the storage unit 185 of the portable apparatus 100. The text arrangement information includes writing method information, text line information, text position information, and the like. The writing method information is information indicating whether the text string is arranged for horizontal writing or vertical writing. The text position information is position coordinate information of each text on the touch panels 190b and 190c. The text line information is information on the line area to which the text belongs. The line region may be divided into a horizontal line region and a vertical line region according to a writing method. For example, when a text string is displayed in a horizontal writing manner, one paragraph is composed of a plurality of horizontal line regions, and texts are arranged on each line region. When a text string is displayed in a vertical writing manner, one paragraph is composed of a plurality of vertical line regions, and texts are arranged on each line region.

Referring to FIG. 6, in the text selection mode, the controller 110 determines whether a touch input is generated in the text area by the electronic pen 200 in step 301. For example, the user may touch the electronic pen 200 at the beginning of the text string to be selected in the displayed paragraph as shown in the first screen 410 of FIG. 8, and a touch input may occur accordingly.

When a touch input occurs, the controller 110 checks whether the touch input is a continuous movement input while continuously moving in step 303, and proceeds to step 305 when the touch input is continuous. That is, if the user touches the touch screen 190 like the first screen 410, and moves the electronic pen 200 underline in the horizontal direction while maintaining the touch, the controller 110 continuously. Will be judged by the move input. If it is not the continuous movement input, the controller 110 proceeds to step 319 and the controller 110 performs a function corresponding to the generated touch input. For example, it may be a touch input for executing a specific menu function.

In step 305, the controller 110 tracks the touch trace corresponding to the continuous movement input of the electronic pen 200, and displays the touch trace on the display panel 190a. For example, as shown in the second screen 420 of FIG. 8, the first horizontal line 430 is displayed under the text column according to the movement trajectory of the electronic pen 200.

When the touch input is terminated in step 307, the controller 110 compares the overall shape of the touch trace with the text selection pattern stored in the storage unit 185 to determine whether a corresponding text selection pattern exists. At this time, even if the touch trajectory does not exactly match the specific text selection pattern, if it is determined that there is similarity over a predetermined reference, the controller 110 determines that the text selection pattern exists. In the example of FIG. 8, it is to check whether there is a text selection pattern similar to the first horizontal line 430, and as a result of the check, the horizontal line pattern 450 will be detected.

If there is no text selection pattern similar to the touch trace as a result of the check in step 307, the controller 110 proceeds to step 319 to perform a function corresponding to the input touch trace. For example, a continuous moving touch corresponding to a scroll function may be input.

If there is a text selection pattern similar to the touch trajectory, the controller 110 checks a line area including a touch start point or a touch end point and a line area located between the touch start point and the touch end point and does not include the touch start point or the touch end point. The selected text is selected between the touch start point and the touch end point on the identified line area, and the text is highlighted. In the example of FIG. 8, as shown in the third screen 440, the touch start point 431 and the touch end point 432 of the first horizontal line 430 are located in the same line region, and the touch start point 431 and the touch end point 432 are located in the same line area. The text column in between is selected and highlighted. As such, the user may select the text string by touching the electronic pen 200 on the touch screen 190 as if the text string to be selected is underlined.

In this case, a plurality of text line regions may be located between the touch start point and the touch end point. For example, when the text selection pattern is a vertical line pattern, an oblique pattern, or a mixed pattern, a plurality of text line areas may be included between the touch start point and the touch end point. In this case, all the texts of the text line area that does not include the touch start point and the touch end point among the plurality of text line areas are selected, and in the text line area including the touch start point or the touch end point, a part of the text line area is based on the touch start point or the touch end point. The text is selected. An example thereof will be described later with reference to FIGS. 9 to 12.

In addition, according to an embodiment of the present invention, when the line is drawn using the electronic pen 200 to a text line adjacent to a selected text column within an effective time (for example, 1 second), the next successive drawing is performed along with the previously selected text column. The text column corresponding to the line can be selected. If a line is drawn below several line regions instead of immediately adjacent text line regions within a valid time period, the entire line can be selected from the preselected text column to the last line region.

6, after performing text selection in step 311, the controller 110 stores the touch start point as the first start point in step 313. This is to prepare for the case where the text selection input is detected within the predetermined valid time as described above. Thereafter, when a touch input generation by the electronic pen 200 is detected in step 315, the control unit 110 proceeds to step 317 and checks whether it is a continuous movement input.

In step 321, the controller 110 checks whether the touch continuous movement input has occurred within the valid time based on the time point at which the touch input ends in step 307, and proceeds to step A of FIG. 7 if it occurs within the valid time. If not, go to step 323. In step 323, the controller 110 releases the previous text selection and deletes the first starting point. In other words, if a touch input occurs after the validity time, the previous text selection is released. Thereafter, the controller 110 proceeds to step 305 to track the touch trace. Steps 305 to 321 are repeated to check whether the touch trajectory is for text selection and perform an operation accordingly.

On the other hand, if it is determined that the touch continuous movement input has occurred within the effective time, the controller 110 proceeds to step A of FIG. 7, maintains the previous text selection in step 325, tracks the touch trajectory in step 327, and touch trajectory. Is displayed on the display panel 190a. 9 illustrates an example of this case, and illustrates an example of a touch input occurring within an effective time after the text string is highlighted as in the third screen 440. Referring to FIG. 9, as shown in the fourth screen 460, the second text is displayed on the second horizontal line under the text column according to the movement trajectory of the electronic pen 200 while maintaining the highlighted text string on the third screen 440. 470).

When the touch input is terminated in step 329, the controller 110 compares the overall shape of the touch trace with the text selection pattern stored in the storage unit 185 to determine whether there is a corresponding text selection pattern.

If there is no text selection pattern similar to the touch trace as a result of the check in step 309, the controller 110 proceeds to step 355 and performs a function corresponding to the input touch trace.

If there is a text selection pattern similar to the touch trajectory, the controller 110 selects the displayed text in the line area between the first start point and the last touch end point stored in step 313. The display then highlights the selected text, proceeds to step B, and proceeds to step 315 of FIG.

Referring to FIG. 9, when the touch input is stopped while the second horizontal line 470 is displayed as shown in the fourth screen 460, the touch start point 471 corresponding to the second horizontal line 470 is displayed. ) And the touch endpoint 471 will be identified. However, since an additional string selection input has occurred within the valid time, the touch start point, which is a reference for text selection, becomes the start point of the previously selected text string, that is, the first start point 431. A string between the first start point 431 and the touch end point 471 corresponding to the last touch end point is selected to display a result screen such as the fifth screen 480. In other words, the controller 110 does not include the line area including the first start point 431 and the touch end point 471, and the first start point 431 and the touch end point 471, but does not include the first start point 431 and the touch end point. The line region located between the lines 471 is checked, and the text displayed between the first start point 431 and the touch end point 471 is selected on the identified line area.

10 is a diagram illustrating an example of text selection input of a vertical line pattern according to an embodiment of the present invention. Referring to FIG. 10, when the user draws a line in the vertical direction on the touch screen 190 with the electronic pen 200, as shown in the sixth screen 510, the vertical line 520 corresponds to the touch trace. 190). Then, when the touch input is stopped, the vertical line 520 and the text selection pattern are compared, and as a result, the vertical pattern 540 will be detected. Accordingly, the touch trajectory corresponding to the vertical line 520 is determined as a valid text selection pattern, and all text strings existing between the touch start point 521 and the touch end point 522 are selected.

That is, although the touch start point 521 or the touch end point 522 is not included, all the texts of the text line area located between the first start point 431 and the touch end point 471 are selected. In the text line area including the touch start point 521, the text is selected in the right direction based on the touch start point 521 to the last character of the text line area. In the text line including the touch end point 522, the text from the first text of the corresponding text line area to the touch end point 522 is selected.

In the above example, a vertical line is drawn from top to bottom, but a line may be drawn from bottom to top. In this case, the selected string is the same, and the text string selected in the text line area including the touch start point or the touch end point will be related to the grammar of the language corresponding to the displayed text.

As described above, the highlighting screen of the selected text string is the same as the seventh screen 530.

11 is a diagram illustrating an example of text selection input of an oblique pattern, according to an embodiment of the present invention. Referring to FIG. 11, when the user draws a line in the diagonal direction on the touch screen 190 with the electronic pen 200, as shown in the eighth screen 610, the diagonal line 620 corresponds to the touch trace. 190). Then, when the touch input is stopped, the diagonal line 620 and the text selection pattern are compared, and as a result, the diagonal pattern 640 will be detected. Accordingly, the touch trajectory corresponding to the diagonal line 620 is determined as a valid text selection pattern, and all text strings existing between the touch start point 621 and the touch end point 622 are selected.

That is, all the texts of the text line area not including the touch start point 621 or the touch end point 622 are selected. In the text line area including the touch start point 621, the text is selected in the right direction based on the touch start point 621 up to the last character of the text line area. In the text line area including the touch end point 622, the text from the first text of the text line area to the touch end point 622 is selected. As such, the selection based on the touch start point 621 or the touch end point 622 may be related to the grammar corresponding to the displayed text.

In the above-described process, the highlighting screen of the selected text string is the same as the ninth screen 630.

12 illustrates an example of text selection input of a mixed pattern, according to an embodiment of the present invention. Referring to FIG. 12, as shown in a tenth screen 510, when a user draws a line by mixing a horizontal direction and a vertical direction on the touch screen 190 with the electronic pen 200, a step shape corresponding to the touch trajectory ( 720 is displayed on the touch screen 190. Then, when the touch input is stopped, the stairs 720 and the text selection pattern are compared, and as a result, the mixed pattern 720 will be detected. The mixed pattern is a pattern in which horizontal lines, vertical lines, and diagonal lines are mixed, and examples of the patterns 740, 750, 760, and 770 are shown in FIG.

Accordingly, the touch trajectory corresponding to the staircase 720 is determined as a valid text selection pattern, and all text strings existing between the touch start point 721 and the touch end point 722 are selected.

That is, all the texts in the line area which are not included in the touch start point 721 or the touch end point 722 but located between the touch start point 721 or the touch end point 722 are selected. In the text line area including the touch start point 721 or the touch end point 700, the left string or the right string based on the grammar of the language corresponding to the text or the touch end point 700. Will be chosen.

As described above, the highlighting screen of the selected text string is the same as the eleventh screen 730.

In the above embodiments, an example of using the text selection pattern has been described. However, according to another exemplary embodiment of the present invention, the text selection pattern may be configured to select text by detecting only a start point and an end point regardless of the shape of the touch trace. This example is shown in FIG.

Referring to FIG. 14, in the text selection mode, the controller 110 determines whether a touch input is generated in the text area by the electronic pen 200 in step 901. If a touch input occurs, the controller 110 checks whether it is a continuous movement input in step 903, and proceeds to step 905 when the touch input is continuous. If it is not the continuous movement input, the controller 110 proceeds to step 915 and the controller 110 performs a function corresponding to the generated touch input. For example, it may be a touch input for executing a specific menu function.

When the touch input ends in step 905, the controller 110 selects the text displayed between the touch start point and the touch end point in step 907 and highlights the corresponding text. The controller 110 stores the touch start point of step 909 as the first start point. In other words, the line area including the touch start point and the touch end point and the line area located between the touch start point and the touch end point are checked, and the text displayed between the touch start point and the touch end point is selected on the identified line area.

Thereafter, when a touch input generation by the electronic pen 200 is detected in step 911, the controller 110 proceeds to step 913 to determine whether the input is a continuous movement input. In step 917, the controller 110 determines whether the touch continuous movement input has occurred within the valid time based on the time point at which the touch input ends in step 905, and proceeds to step 919 if the touch continuous movement input has not occurred within the valid time. In step 919, the controller 110 releases the previous text selection and deletes the first starting point. In other words, if a touch input occurs after the validity time, the previous text selection is released. Thereafter, the controller 110 proceeds to step 905 and repeatedly performs steps 905 to 919.

On the other hand, if it is determined that the touch continuous movement input has occurred within the valid time, the controller 110 maintains the previous text selection in step 921, and when the touch input is terminated in step 923, the first starting point and the last touch previously stored in step 925. Select the text displayed between the end points. The display then highlights the selected text, proceeds to step C, and proceeds to step 911.

As described above, the present invention may provide an intuitive and easy interface to a method of selecting text in a portable device. Compared to the conventional selection method, the operation is similar to that of writing a line with a highlighter, thereby providing a user interface having excellent consistency and intuition with respect to the selection function and operation method. In addition, compared to the two operations using a handler after a long touch input, which is a conventional operation method, the same function can be performed simply by underlining one operation.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. For example, the text selection pattern may be rectangular. In this case, the text string included in the rectangular touch trajectory will be selected. In another embodiment of the present invention, an input device other than the electronic pen 200 may be used. Therefore, the scope of the present invention should not be limited by the described embodiments but should be determined by the equivalents of the claims and the claims.
