Abstract

PROBLEM TO BE SOLVED: To improve operability when designating a movement destination of a cursor by a position of a touch operation on a touch panel.
If a tap operation is performed on a text display area while an edit target text is displayed, the character spacing of the edit target text becomes wide. If the slide operation is performed on the text display area 21 in this state, the text to be edited can be scrolled. If a tap operation is performed, the cursor 25 moves to the operation position, and the character spacing is restored. For this reason, the first tap operation is an operation for widening the character spacing of the text to be edited, not an operation for designating a part of the text to be edited. Therefore, strictness is not required for the operation position, the cursor moving operation is facilitated, and the operability of the text editing terminal can be improved.

Description

  The present invention relates to a text editing terminal, and more particularly to an improvement of a text editing terminal provided with a touch panel for displaying a text to be edited.

  In general, text editing using an information processing terminal is performed by moving a cursor between characters or characters in the text while the text to be edited is displayed on the display, and inserting or deleting characters at the position of the cursor. Is done by instructing. At this time, the movement of the cursor is usually performed by pressing a direction key associated with the up / down / left / right movement directions.

  On the other hand, recent portable information terminals such as mobile phones and tablet computers often have a touch panel. In such a portable information terminal, if a touch operation on the touch panel is performed, the cursor can be moved to the operation position. Therefore, the operation can be performed intuitively, and the operation time and the number of operations are not increased according to the movement distance of the cursor. However, when the characters displayed on the touch panel are small, there is a problem that it is not easy to move the cursor as intended by the user. In particular, in the case of a portable information terminal, there is a problem that it is difficult to move the cursor as intended because the touch panel is small and the displayed characters are small.

  For such a problem, a portable information terminal that enlarges and displays a word in a text by a touch operation is conventionally known (for example, Patent Document 1). In the portable information terminal described in Patent Document 1, one word is selected by a touch operation, a small window for displaying the word in an enlarged manner is displayed, and the word can be edited in the small window. This small window is closed when another word is selected and a new small window is displayed. That is, in this portable information terminal, the position of the cursor can be specified for the enlarged word.

  A portable information terminal is also known in which a position touched by a user and its peripheral area are enlarged and displayed in a small window, and a cursor position can be designated in the small window.

  However, in these portable information terminals, the touch-operated position and its peripheral area are enlarged and displayed in a small window. For this reason, when the operation position of the touch operation for opening the small window is not appropriate, the position to be designated as the movement destination of the cursor is not displayed in the small window. In such a case, it is necessary to repeat a touch operation for opening a small window, which is complicated.

JP 2007-299394 A

  The present invention has been made in view of the above circumstances, and an object thereof is to improve the operability of a text editing terminal provided with a touch panel. In particular, the object is to improve the operability of cursor movement during text editing. It is another object of the present invention to improve the operability when designating the movement destination of the cursor by the operation position of the touch operation.

  A text editing terminal according to a first aspect of the present invention is a character spacing control means for designating a character spacing of text to be edited, a text display control means for displaying the text to be edited on the touch panel at the character spacing, and a touch on the touch panel. Touch operation detecting means for detecting an operation and cursor control means for controlling a cursor position in the text to be edited based on the touch operation, wherein the character spacing control means has a narrow character spacing. The character interval is changed to a wide interval based on the touch operation in the case, and the cursor control means moves the cursor position to the touch operation based on the touch operation when the character interval is the wide interval. It is comprised so that it may change to the operation position.

  With such a configuration, if the touch operation is performed in a state where the text to be edited is displayed so that the character interval is narrow, the character interval is changed to a wide interval, and then if the touch operation is further performed, The cursor can be moved to the operation position. That is, the preceding touch operation is an operation for widening the character spacing of the text to be edited, and is not an operation for designating a part of the text to be edited as in the prior art. For this reason, the preceding touch operation does not need to be performed on the new cursor position or its periphery, and strictness is not required for the operation position. Therefore, the cursor movement operation is facilitated, and the operability of the text editing terminal can be improved.

  A text editing terminal according to a second aspect of the present invention includes, in addition to the above configuration, scroll control means for scrolling the text to be edited displayed on the touch panel, and the touch operation detection means performs an operation during the touch operation. First and second touch operations that can be distinguished from each other based on a change in position are detected, respectively, and the cursor control means performs the above operation based on the first touch operation when the character interval is the wide interval. The cursor position is changed, and the scroll control means is configured to scroll the text to be edited based on a second touch operation when the character spacing is the wide spacing.

  With such a configuration, when the character spacing is wide, the second touch operation is performed to scroll the text to be edited on the touch panel before the first touch operation is performed and a new cursor position is designated. Can be made. Therefore, when the entire text to be edited is not displayed on the touch panel and the new cursor position is not displayed, the text to be edited is first scrolled by the second touch operation, and the new cursor position is set. If the first touch operation is performed after being displayed on the touch panel, the cursor can be moved between arbitrary characters or characters in the text to be edited.

  In the text editing terminal according to the third aspect of the present invention, in addition to the above configuration, the character spacing control means sets the character spacing to a wide spacing based on a first touch operation when the character spacing is the narrow spacing. Configured to change to

  With such a configuration, if two types of touch operations on the touch panel are identified, it is possible to sequentially change the character spacing, scroll the text to be edited, and specify a new cursor position. Therefore, the cursor movement operation is facilitated, and the operability of the text editing terminal can be improved.

  In a text editing terminal according to a fourth aspect of the present invention, in addition to the above configuration, the character spacing control means reduces the character spacing based on a first touch operation when the character spacing is the wide spacing. Configured to change to interval.

  With such a configuration, the cursor position can be changed to the operation position of the touch operation and the character interval can be changed to a narrow interval based on the touch operation when the character interval is wide. That is, when the movement of the cursor is completed, the character interval is automatically returned to a narrow interval, so that the cursor movement operation is further facilitated and the operability of the text editing terminal can be improved.

  In the text editing terminal according to the fifth aspect of the present invention, in addition to the above configuration, the first touch operation includes a tap operation, and the second touch operation includes a slide operation.

  In addition to the above configuration, the text editing terminal according to the sixth aspect of the present invention is configured such that the scroll control means determines the scroll direction of the text to be edited based on the slide direction of the slide operation.

  According to a seventh aspect of the present invention, there is provided a text editing terminal control method that detects a character spacing control step for controlling a character spacing, a display control step for displaying text to be edited on the touch panel at the character spacing, and a touch operation on the touch panel. A touch operation detecting step, and a cursor control step for controlling a cursor position in the text to be edited based on the character interval and the touch operation. In the character interval control step, the character interval is a narrow interval. Based on the touch operation in a certain case, the character interval is changed to a wide interval, and in the display control step, the characters constituting the text to be edited and the entire character displayed on the touch panel are converted to the character In the cursor control step, the character spacing is the wide spacing. Based on the touch operations when that changes the cursor position.

  ADVANTAGE OF THE INVENTION According to this invention, the operativity of the text editing terminal provided with the touch panel can be improved. In particular, the operability of moving the cursor during text editing can be improved. In addition, it is possible to improve the operability when designating the movement destination of the cursor by the operation position of the touch operation.

It is the figure which showed an example of the display in the text display area 21 of FIG. It is the figure which showed the other example of the display in the text display area 21 of FIG. It is the figure which showed the further another example of the display in the text display area 21 of FIG. It is the block diagram which showed an example of the internal structure of the mobile telephone 1 of FIG. 1, and the principal part of hardware constitutions is shown. It is the block diagram which showed an example of the internal structure of the mobile telephone 1 of FIG. 1, and the principal part of a functional structure is shown. 5 is a flowchart showing an example of the operation of the mobile phone 1.

  FIG. 1 is an external view showing an example of a text editing terminal according to an embodiment of the present invention. A mobile phone 1 is shown as an example of a text editing terminal. The mobile phone 1 is formed of a thin casing having a substantially rectangular operation surface, and a touch panel 10, a receiver 11, and a microphone 12 are disposed on the operation surface.

  The touch panel 10 includes a display device 10A for displaying an image on a display surface and a touch sensor 10B that detects a user's touch operation on the display surface. For example, a liquid crystal display panel is used for the display device 10A, and a capacitive sensor is used for the touch sensor 10B. When the user performs a touch operation on an arbitrary icon 13 in a state where two or more icons 13 are displayed on the display surface, the operation position of the touch operation is detected, and the touched icon 13 is selected. Is done. The receiver 11 and the microphone 12 are voice input / output devices for calls.

  In the present embodiment, an example of the mobile phone 1 will be described. However, the text editing terminal according to the present invention may be an information terminal that can perform text editing using the touch panel 10, and may be a communication function or a telephone function. It is not limited to the terminal which has. In addition, the present invention is particularly suitable for a portable terminal having a small touch panel 10, but can be applied to other than the portable terminal.

  FIG. 2 is a diagram showing an example of the display on the touch panel 10 in FIG. 1, and shows a text editing screen. 1 can display a text editing screen on the touch panel 10 and edit text data. For example, the body of an email can be edited while the email application is running. The text data is data consisting of a permutation of two or more character codes, that is, character string data, and may be added with a line feed code or character decoration information.

  On the text editing screen, a text display area 21 in which the text to be edited is displayed, a conversion candidate display area 22 in which two or more character conversion candidates are displayed, and a button display in which two or more operation buttons 24 are displayed. Region 23 is included.

  The user can perform backspace input, cursor movement, kana character input, and the like by performing a touch operation on the operation buttons 24. For example, if the operation button 24 for backspace is operated, one character immediately before the cursor position in the text display area 21 is deleted. Further, if the operation button 24 for moving the cursor is operated, the cursor can be moved by one character in the text to be edited. Further, by operating the operation button 24 for inputting kana characters, it is possible to input kana characters.

  When a character string consisting of one or more kana characters is input by a user operation, one or more conversion candidates obtained by automatically converting the character string are displayed in the conversion candidate display area 22. If the user selects any of these conversion candidates, the selected conversion candidate is inserted as a confirmed character string at the cursor position in the text display area 21.

  FIGS. 3A to 3D are diagrams showing an example of display in the text display area 21, in which the state of text editing accompanying the movement of the cursor 25 is shown in time series. FIG. 3A shows a state where the user performs a touch operation on the text display area 21 in which the edit target text is displayed. This touch operation is an operation for increasing the character spacing of the text to be edited, and includes, for example, a tap operation. Since the change of the character spacing is applied to the entire text to be edited, the touch operation may be an operation on the text display area 21, the operation position is arbitrary, and the operation position is the same as in the prior art. It doesn't have to be accurate.

  FIG. 3B shows a state where the movement destination of the cursor 25 is designated by a touch operation in a state where the text to be edited is displayed with a wide character interval. Here, since “Yes” in the text to be edited is an error in “ka”, a touch operation is performed between the characters immediately after “Yes” in order to correct the error, and the new character position is changed between the characters. Specified as Here, the character space closest to the operation position of the touch operation is designated as the new cursor position, so that it can be operated intuitively unlike the case where the touch operation is performed on the operation button 24 for moving the cursor. The operation time and the number of operations do not increase according to the movement distance of the cursor 25. Moreover, in the present embodiment, since the character spacing of the text to be edited is widened in advance, a new cursor position can be easily specified.

  FIG. 3C shows a state after the cursor is moved. The cursor 25 moves between the characters designated by the touch operation in FIG. In addition, the character spacing becomes narrower and returns to the same character spacing as in FIG. That is, if a touch operation for designating the cursor position is performed, the cursor 25 moves, and the widened character interval is narrowed and restored. For this reason, the user does not need to separately perform an operation of returning the character spacing.

  FIG. 3D shows a state after text editing. That is, after the cursor 25 is moved, the backspace operation button 24 is operated to delete “OK”, then the kana character input operation button 24 is operated to input “ka”, and the error is corrected. The state is shown.

  In FIG. 3, an example in which the cursor position is between characters has been described. However, even if the cursor position is a character, the cursor position can be easily increased by widening the space between characters. It can be specified and is unlikely to cause erroneous operations.

  FIGS. 4A to 4D are diagrams showing other examples of display in the text display area 21. In the same manner as in FIG. 3, the state of text editing accompanying the movement of the cursor 25 is time-sequentially. It is shown. 4A shows a state in which the user performs a touch operation on an arbitrary area in the text display area 21 in order to widen the character spacing of the text to be edited, as in FIG. 3A. Has been.

  FIG. 4B shows a state in which the text to be edited is scrolled by a touch operation while the text to be edited is displayed with a wide character interval. The text to be edited is scrolled by a sliding operation in the text display area 21. The slide operation is a touch operation that moves the operation position during the touch operation from touchdown to touchup. The mobile phone 1 includes a slide operation that involves movement of the operation position and a tap operation that does not involve movement of the operation position. Can be detected and each can be detected.

  Here, duplication of “de” in “begin here” in the text to be edited is an error, and in order to correct the error, for example, a touch operation between characters immediately after “de” is performed, It is necessary to move the cursor 25 between the characters. However, due to the increase in the character spacing, the space between characters to be touched is not displayed in the text display area 21. For this reason, an upward slide operation is performed in order to sucrose the text to be edited upward.

  FIG. 4C shows a state in which the movement destination of the cursor 25 is designated by a touch operation after the text to be edited is scrolled. By scrolling the text to be edited, the space between the characters immediately after “de”, which is the movement destination of the cursor, is displayed in the text display area 21. For this reason, as in the case of FIG. 3B, a touch operation is performed between the characters, and the space between the characters is designated as a new cursor position.

  FIG. 4D shows a state after the cursor is moved. The cursor 25 moves between characters designated as the operation position by the touch operation in FIG. In addition, the character spacing becomes narrower and returns to the same character spacing as in FIG. Thereafter, if the user operates the backspace operation button 24 to delete the duplicate character “de”, the error is corrected.

  FIGS. 5A to 5D are diagrams showing still other examples of display in the text display area 21. As in FIGS. 3 and 4, the state of text editing with cursor movement is time-sequential. It is shown. FIG. 5A shows a state in which the user performs a touch operation on an arbitrary area in the text display area 21 in order to widen the character spacing of the text to be edited, as in FIG. 4A. Yes.

  FIG. 5B shows a state in which the text to be edited is scrolled by a touch operation while the text to be edited is displayed with a wide character interval. In FIG. 4B, since the character spacing is increased while keeping the line width constant, the line feed position changes. On the other hand, in FIG. 5B, the line width is widened because the character spacing is widened while keeping the line feed position constant. As a result, the line feed position in the text to be edited does not change, but a part of the line of the text to be edited is not displayed on the text display area 21, and the text to be edited can be scrolled in the horizontal direction.

  Here, since the “field” in the text to be edited is an error in “da”, in order to correct the error, a touch operation is performed between the characters immediately after “field” and the cursor is moved between the characters. 25 needs to be moved. However, due to the increased character spacing, the space between characters to be touched is not displayed in the text display area 21. For this reason, a sliding operation in the right direction is performed to sucrose the text to be edited in the right direction.

  FIG. 5C shows a state in which the movement destination of the cursor 25 is designated by a touch operation after the text to be edited is scrolled. By scrolling the text to be edited, the space immediately after the “field” to be the new cursor position is displayed in the text display area 21. For this reason, as in the case of FIG. 4C, a touch operation is performed between the characters, and the character space is designated as a new cursor position.

  FIG. 5D shows a state after the cursor is moved. The cursor 25 moves between characters designated as the operation position by the touch operation in FIG. In addition, the character spacing becomes narrower and returns to the same character spacing as in FIG. After that, after the user operates the backspace operation button 24 to delete the character “field”, the user operates the kana character input operation button 24 to input “da”, and the error is corrected. It is shown.

  FIG. 6 is a block diagram showing an example of the internal configuration of the mobile phone 1 of FIG. 1, showing the main part of the hardware configuration. The mobile phone 1 includes a microprocessor 30, a program storage unit 31, a text information storage unit 32, an RF unit 33, a touch panel 10, a receiver 11, and a microphone 12.

  The microprocessor 30 can read the text editing program from the program storage unit 31 and execute it. The text editing program is a program for editing text data held in the text information storage unit 32 using the touch panel 10. The text data is edited by displaying the text data on the display device 10A and detecting the touch operation of the user by the touch sensor 10B.

  The program storage unit 31 uses at least a nonvolatile storage device such as a ROM or a flash memory. On the other hand, the text information storage unit 32 uses at least a rewritable storage device such as a RAM or a flash memory. The RF unit 33 is a communication circuit that performs wireless communication with a cellular base station, and performs transmission and reception of data including a call sound and an electronic mail.

  FIG. 7 is a block diagram showing an example of the internal configuration of the mobile phone 1 of FIG. 1, showing the main part of the functional configuration. The mobile phone 1 includes a display device 10A, a touch sensor 10B, a text information storage unit 32, a touch operation detection unit 51, a character spacing control unit 52, a cursor control unit 53, a scroll control unit 54, a text display control unit 55, and a text editing. Part 56.

  The touch operation detection unit 51 is a touch operation detection unit that detects a touch operation on the touch sensor 10B based on an output signal of the touch sensor 10B. The touch operation detection unit 51 can discriminate and detect two types of touch operations, for example, a tap operation and a slide operation. The discrimination between the tap operation and the slide operation is performed based on a change in the operation position during the touch operation. Also, the slide direction of the slide operation is determined. These determination results are output as detection signals to the character spacing control unit 52, the cursor control unit 53, the scroll control unit 54, and the text editing unit 56.

  The character spacing control unit 52 switches the character spacing of the text to be edited displayed on the touch panel 10 to either a narrow spacing or a wide spacing based on a touch operation on the touch panel 10. For example, a normal character interval for text display can be a narrow interval, and a character interval wider than this narrow interval can be a wide interval. Here, it is assumed that the character spacing control unit 52 switches the character spacing based on a tap operation on the text display area 21. That is, if the tap operation is performed when the character interval is narrow, the character interval is changed to a wide interval, and if the tap operation is performed when the character interval is wide, the character interval is changed to a narrow interval. To do.

  The character spacing specified by the character spacing control unit 52 is not applied to a part of the text to be edited displayed on the touch panel 10 but applied to the whole text to be edited displayed on the touch panel 10. . Further, the character spacing designated by the character spacing control unit 52 does not designate a specific spacing length, but may designate which of two predetermined spacing lengths is selected. For example, in the case of adopting a display method that varies the character spacing between characters according to the combination of the adjacent characters, narrow and wide spacing lengths are predetermined for each character, You may comprise so that the character space | interval control part 52 may designate which of those to select as a character space | interval.

  The cursor control unit 53 controls the cursor position in the text display area 21 based on a touch operation on the touch panel 10. The position of the cursor 25 is a reference position for specifying a character to be edited, and the cursor 25 can be moved within the text to be edited. Here, based on a tap operation on the text display area 21 when the character spacing is wide, the cursor 25 is moved to the operation position.

  In other words, when the character spacing is wide, when the tap operation is performed on the text display area 21, the cursor control unit 53 moves the cursor 25, and the character spacing control unit 52 narrows the character spacing. Change to

  The scroll control unit 54 performs control to scroll the text to be edited based on a touch operation on the touch panel 10. Here, the text to be edited is crawled in the text display area 21 based on a slide operation when the character spacing is wide. The scroll direction is made to coincide with the direction of the slide operation. For example, it is possible to scroll in either the upper or lower direction according to the direction of the slide operation. Alternatively, it may be configured to scroll in one of up, down, left and right directions depending on the direction of the slide operation.

  The text display control unit 55 generates image data to be displayed in the text display area 21 based on the edit target text data held in the text information storage unit 32, and outputs the image data to the display device 10A. For the generation of the image data, the character spacing designated by the character spacing control unit 52, the cursor position designated by the cursor control unit 53, and the scroll control information designated by the scroll control unit 54 are used.

  That is, the image data is generated so that the character spacing designated by the character spacing control unit 52 becomes the character spacing of the text to be edited. In addition, the character specified as the cursor position by the cursor control unit 53 or image data in which the cursor 25 is displayed between the characters is generated. Further, image data for performing scroll display designated by the scroll control unit 54 is displayed.

  The text editing unit 56 updates the text to be edited in the text information storage unit 32 based on the touch operation on the operation button 24.

  Steps S101 to S106 in FIG. 8 are flowcharts showing an example of the operation of the mobile phone 1, and show a cursor movement process that is executed when a touch operation on the text display area 21 is detected.

  First, the touch operation detection unit 51 determines whether the detected touch operation is a tap operation or a slide operation (step S101). If the operation is a slide operation, the edit target text is scrolled and the cursor movement process is terminated (step S102).

  If the touch operation is a tap operation in step S101, the character spacing control unit 52 determines whether the current character spacing is a narrow spacing or a wide spacing (step S102). And if it is a narrow space | interval, a character space | interval will be changed into a wide space | interval and the said cursor movement process will be complete | finished. That is, the text to be edited is displayed at wide intervals in the text display area 21 of the display device 10A.

  In step S103, when the current character interval is a wide interval, the cursor control unit 53 changes the cursor position, and the cursor 25 moves to the operation position of the touch operation (step S105). In addition, the character interval control unit 52 changes the character interval to a narrow interval, and the cursor movement process ends (step S106).

  In the flowchart of FIG. 8, an example in which scroll display is performed when a slide operation is performed regardless of whether the character interval is a narrow interval or a wide interval has been described. However, at least the character interval is a wide interval. In such a case, the scroll display may be performed.

  The cellular phone 1 according to the present embodiment includes a character spacing control unit 52 that specifies the character spacing of the text to be edited, and text display control that displays the editing target text on the touch panel 10 at the character spacing specified by the character spacing control unit 52. Unit 55, a touch operation detection unit 51 that detects a touch operation on the touch panel 10, and a cursor control unit 53 that controls a cursor position in the text to be edited based on the touch operation. The character interval is changed to a wide interval based on the touch operation when the character interval is narrow, and the cursor control unit 53 touches the cursor position based on the touch operation when the character interval is wide. It is configured to change to the operation position of the operation.

  With such a configuration, if the touch operation is performed in a state where the text to be edited is displayed so that the character interval is narrow, the character interval is changed to a wide interval, and then if the touch operation is further performed, The cursor can be moved to the operation position. That is, the preceding touch operation is an operation for widening the character spacing of the text to be edited, and is not an operation for designating a part of the text to be edited as in the prior art. For this reason, the preceding touch operation does not need to be performed on the new cursor position or its periphery, and strictness is not required for the operation position. Therefore, the cursor movement operation is facilitated, and the operability of the text editing terminal can be improved.

  In addition, the mobile phone 1 according to the present embodiment includes a scroll control unit 54 that scrolls the edit target text displayed on the touch panel 10, and the touch operation detection unit 51 is based on a change in the operation position during the touch operation. A tap operation and a slide operation that can be distinguished from each other are detected, and the cursor control unit 53 changes the cursor position based on the tap operation when the character interval is wide, and the scroll control unit 54 determines that the character interval is The edit target text displayed on the touch panel 10 is scrolled based on a slide operation in the case of a wide interval.

  With such a configuration, when the character spacing is wide, the text to be edited can be scrolled on the touch panel 10 by performing a slide operation before performing a tap operation and designating a new cursor position. For this reason, when the entire text to be edited is not displayed on the touch panel and a new cursor position is not displayed, the text to be edited is first scrolled by a slide operation, and the new cursor position is displayed on the touch panel 10. If the tap operation is performed after the display, the cursor can be moved between any characters in the text to be edited or between characters.

  The text editing terminal according to the present invention is configured such that the character spacing control unit 52 changes the character spacing to a wide spacing based on a tap operation when the character spacing is a narrow spacing. With such a configuration, if a tap operation and a slide operation on the touch panel 10 are identified, it is possible to sequentially change the character spacing, scroll the text to be edited, and specify a new cursor position. Therefore, the cursor movement operation is facilitated, and the operability of the text editing terminal can be improved.

  Further, the text editing terminal according to the present invention is configured such that the character spacing control unit 52 changes the character spacing to a narrow spacing based on a tap operation when the character spacing is wide. With such a configuration, the cursor position can be changed to the operation position of the touch operation and the character interval can be changed to a narrow interval based on the tap operation when the character interval is a wide interval. That is, when the movement of the cursor position is completed, the character interval automatically returns to a narrow interval, so that the cursor movement operation is further facilitated and the operability of the text editing terminal can be improved.
