  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a mobile terminal 10 such as a smartphone or a tablet terminal will be described as an example of an electronic device that receives an input via a touch panel.

  FIG. 1 is a diagram illustrating a hardware configuration example of a mobile terminal according to the present embodiment. In FIG. 1, the portable terminal 10 includes a CPU 11, a memory 12, an auxiliary storage device 13, a touch panel 14, and the like.

  The auxiliary storage device 13 stores a program installed in the mobile terminal 10. The memory 12 reads the program from the auxiliary storage device 13 and stores it when there is an instruction to start the program. The CPU 11 realizes functions related to the mobile terminal 10 according to a program stored in the memory 12.

  The touch panel 14 is an electronic component having both an input function and a display function, and displays information, accepts input from a user, and the like. The touch panel 14 includes a display device 15 and an input device 16.

  The display device 15 is a liquid crystal panel or the like, and bears the display function of the touch panel 14. The input device 16 is an electronic component including a sensor that detects contact of a contact object with the display device 15. The contact detection method of the contact object may be any known method such as an electrostatic method, a resistive film method, or an optical method. The input device 16 outputs a set of coordinates (hereinafter referred to as “sensor coordinates”) of sensors that react to the contact object (that is, the contact is detected). The contact object refers to an object that contacts the touch panel 14. Examples of such an object include a user's finger and a dedicated or general pen.

  Subsequently, the operation procedure of the character string in the first embodiment will be described. FIG. 2 is a diagram for explaining an example of a character string operation procedure according to the first embodiment. FIG. 2 shows an example of an operation procedure when a character string to be copied or cut is specified. The designation of the character string to be copied or cut is to copy or move a part or all of the character string in the displayed document data to another part of the document data or other document data. And temporarily storing in a predetermined area of the memory 12. The predetermined area is also called a clipboard.

  As shown in the operation procedure (1), the user presses and holds two points on the touch panel 14, that is, the beginning and the end of the character string to be operated. The long press refers to an operation in which the touch state (contact state) continues for a predetermined time or longer.

  Subsequently, in the operation procedure (2), the character string between the two points is selected. By selecting the character string between the two points, the user can confirm the character string to be operated.

  Subsequently, in the operation procedure (3), the user rotates the two points clockwise (clockwise) or counterclockwise (counterclockwise). In the figure, an example of rotating clockwise is shown. For example, in the clockwise direction, it is determined that the operation requested by the user is copying. In the case of counterclockwise rotation, it is determined that the operation requested by the user is cut. However, the counterclockwise direction may be assigned to the copy, and the clockwise direction may be assigned to the cut. In either case of copying or cutting, the character string to be operated is stored in a storage area such as a clipboard. In the case of cutting, the character string to be cut is deleted from the document data.

  For each of the two contact points, the clockwise direction is a clockwise direction when the other contact point is assumed to be the rotation axis. Similarly, the counterclockwise direction is a counterclockwise direction when the other rotation axis is assumed as the center point.

  Moreover, both contact points do not need to rotate. The operation procedure (3) may be realized by rotating the other contact point while the one contact point is fixed.

  According to the operation procedure as described above, for example, the user can specify a character string to be copied or cut by touching the touch panel 14 with two fingertips and rotating the touched fingertips as they are. .

  In order to realize the operation procedure shown in FIG. 2, the mobile terminal 10 of the first embodiment has a functional configuration as shown in FIG. 3, for example.

  FIG. 3 is a diagram illustrating a functional configuration example of the mobile terminal according to the first embodiment. 3, the mobile terminal 10 includes a two-point contact detection unit 101, a character string selection unit 102, a movement detection unit 103, an operation type determination unit 104, a character string operation unit 105, and the like. Each of these units is realized by processing executed by the CPU 11 by a program installed in the mobile terminal 10. The mobile terminal 10 also has a character string storage unit 106. The character string storage unit 106 can be realized using the memory 12 or the like, for example.

  The two-point contact detection unit 101 detects two-point contact on the touch panel 14. The character string selection unit 102 selects a character string between two points detected by the two-point contact detection unit 101, that is, a character string to be operated. In addition, the character string selection unit 102 stores the character positions corresponding to the two contact points in the memory 12. The character position is, for example, the character position in the entire character string of the currently displayed document data.

  The movement detection unit 103 detects the movement of at least one of the two contact points. The operation type determination unit 104 determines the operation type requested by the user based on the movement mode (movement trajectory or the like) detected by the movement detection unit 103. The operation type is a type of copying or cutting. The character string operation unit 105 stores the operation target character string in the character string storage unit 106. If the determination result by the operation type determination unit 104 is cut, the character string operation unit 105 deletes the operation target character string from the document data.

  The character string storage unit 106 is a storage unit corresponding to the above-described clipboard. That is, the character string storage unit 106 stores a character string to be copied or cut.

  Hereinafter, the process procedure which the portable terminal 10 of 1st embodiment performs is demonstrated. FIG. 4 is a flowchart for explaining an example of a processing procedure executed by the mobile terminal according to the first embodiment.

  For example, when the user touches two arbitrary points on the touch panel 14 with two fingertips, the two-point contact detection unit 101 detects two contact points (S101). If the contact state between the two contact points is released before continuing for a predetermined time or longer (No in S102), the process in FIG. 4 ends. When the contact state between the two contact points continues for a predetermined time or longer (Yes in S102), the character string selection unit 102 selects the character string between the two points, that is, the operation target character string (S103). At this time, the character string selection unit 102 stores the character positions corresponding to the two contact points in the memory 12.

  Subsequently, when the user moves at least one of the two fingertips, the movement detection unit 103 detects the movement of the contact point (Yes in S104). Subsequently, the operation type determination unit 104 determines whether the movement mode of the contact point is right rotation or left rotation (S105). In the case of right rotation (Yes in S105), the character string operation unit 105 stores a character string between two character positions stored in the memory 12 in the character string storage unit 106 (S106). In the case of left rotation (No in S105), the character string operation unit 105 stores a character string between two character positions stored in the memory 12 in the character string storage unit 106 (S107). Subsequently, the character string operation unit 105 deletes the character string from the document data to be displayed (S108).

  In the operation procedure (3) in FIG. 2, the movement of the contact point for specifying copy or cut may not be rotation. For example, copy or cut may be designated by pinch-in and pinch-out.

  FIG. 5 is a diagram showing a modification of the copy or cut designation method. FIG. 5 shows an example of pinch-in. For example, pinch-in is assigned to the cut and pinch-out is assigned to the copy. The operation assigned to cut or copy may be reversed. Note that pinch-in refers to an operation in which two contact points move so as to approach each other in opposing directions. Pinch out refers to an operation in which two contact points move away from each other in opposite directions. Both the pinch-in and the pinch-out do not necessarily need to move both contact points. Pinch-in or pinch-out may be performed by moving only one contact point.

  When the operation as shown in FIG. 5 is adopted in the operation procedure (3), in step S105 in FIG. 4, the operation type determination unit 104 determines whether the touch point movement mode is pinch-in or pinch-out. That's fine.

  In the case of cutting, the character string to be cut is deleted from the original position. Therefore, in a case where a range unintended by the user has been deleted, for example, the character string operation unit 105 performs a pop-up for restoring it as shown in FIG. 6 after deleting the character string to be cut. May be displayed.

  FIG. 6 is a diagram showing a display example of a pop-up for returning to the original state. FIG. 6 shows an example in which a pop-up P <b> 1 including a message “return to original” is displayed at a position where there is a character string to be cut. When the pop-up P1 is touched, the character string operation unit 105 places the deleted character string at the original position.

  As described above, according to the first embodiment, it is possible to specify copying or cutting of a character string by a simple operation. Therefore, the operability of the character string via the touch panel 14 can be improved.

  Next, a second embodiment will be described. In the second embodiment, differences from the first embodiment will be described. Accordingly, points not particularly mentioned may be the same as those in the first embodiment.

  In the second embodiment, an operation procedure for realizing cut and paste by a series of operations will be described. FIG. 7 is a diagram for explaining an example of a character string operation procedure according to the second embodiment.

  In FIG. 7, the operation procedure (1) and the operation procedure (2) are the same as those in FIG. In the operation procedure (3), the user slides one of the two contact points to the movement destination of the character string to be operated while maintaining the contact state. In the figure, an example in which the start point slides is shown. As a result, the character string to be operated moves to the slide destination position. That is, cut and paste is realized.

  Note that sliding may be performed while the contact state between the two contact points is maintained. In this case, the position of the destination of the character string may be given priority to either the start point or the end point stop position. In the following description, a case where any one of the two contact points is slid will be described.

  Further, the locus of the contact point at the time of sliding does not necessarily have to be linear, and may be curved. When the two contact points are slid, the two points should be slid in the same direction, being substantially parallel.

  FIG. 8 is a flowchart for explaining an example of a processing procedure executed by the mobile terminal according to the second embodiment. Steps S201 to S203 are the same as steps S101 to S103 in FIG.

  Subsequently, the movement detection unit 103 waits until the contact state of one of the two contact points is released (S204). The release of the contact state means that a finger or the like that has been in contact leaves the touch panel 14. If the contact state of both of the two contact points is canceled (No in S204) before the contact state of any one of the two contact points is canceled (No in S204), the process of FIG. finish.

  When the contact state of one of the two contact points is released (Yes in S204), the movement detection unit 103 waits until the contact point is slid while the contact state is maintained (S206). If the contact state of both of the two contact points is released before the contact point is slid (No in S206) (Yes in S207), the process in FIG. 8 ends.

  When the sliding of one contact point is started (Yes in S206) and the slide is stopped (Yes in S208), the movement detection unit 103 waits until the contact state of the contact point is released (S209). The movement detection unit 103 stores the position of the character corresponding to the contact point when the slide is stopped in the memory 12.

  When the movement detection unit 103 detects the release of the contact state of the contact point (Yes in S209), the position of the character in the document data (hereinafter referred to as “movement destination position”) corresponding to the release position of the contact state. Store in memory 12. The operation type determination unit 104 determines that the requested operation is a movement of a character string based on a single contact state slide or the like. Therefore, the character string operation unit 105 moves the character string to be operated to the movement destination position (S210). That is, the character string is deleted from the original position and inserted at the destination position.

  Similar to the first embodiment, after the character string is moved, a pop-up P1 for returning to the original may be displayed.

  Further, when the sliding in the contact state between the two contact points is permitted, steps S204 and S205 may not be executed.

  Furthermore, the operation in the second embodiment may be assigned to copying instead of moving. That is, the character string to be operated need not be deleted from the original position.

  As described above, according to the second embodiment, the movement of the character string can be realized by a simple operation. Therefore, the operability of the character string operation via the touch panel 14 can be improved.

  Next, a third embodiment will be described. In the third embodiment, differences from the first embodiment will be described. Accordingly, points not particularly mentioned may be the same as those in the first embodiment.

  In the third embodiment, an operation procedure for specifying a copy or cutout range will be described. FIG. 9 is a diagram for explaining an example of a character string operation procedure according to the third embodiment.

  In FIG. 9, the operation procedure (1) and the operation procedure (2) are the same as those in FIG. In the operation procedure (3), when the user moves the other contact point while fixing one contact point, the selection range changes according to the moving direction. In the figure, an example is shown in which the end point side of the character string to be operated is the rotation axis and the start point is moving. When the rotation direction is right, the start point of the selection range moves in a direction in which the selection range is reduced. When the rotation direction is left, the start point of the selection range moves in the direction in which the selection range is expanded. As shown in FIG. 9, when the starting point of the initial selection range matches the starting point of the display range, the selection range expands when the character corresponding to the starting point is a character in the middle of the document data. In this case, scrolling may be performed so that the upper character string that is not displayed is included in the selection range.

  On the other hand, when the start point side of the character string to be operated is a rotation axis and the end point moves, the end point side expands and contracts. Specifically, when the rotation direction is right, the end point of the selection range moves in a direction in which the selection range is reduced. When the rotation direction is left, the end point of the selection range moves in the direction in which the selection range is expanded. In addition, when the end point of the initial selection range matches the end point of the display range, and the selection range is widened when the character corresponding to the end point is a character in the middle of the document data, it is displayed. Scrolling may be performed so that the lower character string not included is included in the selection range.

  FIG. 10 is a flowchart for explaining an example of a processing procedure executed by the mobile terminal according to the third embodiment. Steps S301 to S304 are the same as steps S101 to S104 in FIG.

  In step S305, the operation type determination unit 104 determines whether or not the manner of movement of the contact point is right rotation about the one contact point as a rotation axis (S305). When the manner of movement of the contact point is right rotation with one contact point as the rotation axis (Yes in S305), the character string operation unit 105 reduces the selection range with respect to the contact point side different from the rotation axis. (S306).

  When the contact point movement mode is a left rotation with one contact point as the rotation axis (Yes in S307), the character string operation unit 105 expands the selection range on the contact point side different from the rotation axis. (S308).

  Subsequently, when the contact state of both of the two contact points is canceled (Yes in S309), the character string operation unit 105 stores the character string in the selected range in the character string storage unit 106 (S310). In this case, the character string may be a copy target or a cut target. For example, the character string may be a copy target when the starting point side finger is released first, and the character string may be a cutting target when the end point finger is released first. Or vice versa. The designation of copying or cutting may be performed by another operation. Further, the character string in the selection range may be a target of an operation other than copying or cutting. When the character string in the selection range is to be cut out, the character string operation unit 105 deletes the character string from the document data.

  As described above, according to the third embodiment, the selection range can be changed by a simple operation of two contact points. Therefore, the operability of the character string operation via the touch panel 14 can be improved.

  Next, a fourth embodiment will be described. In the fourth embodiment, an example in which the first to third embodiments are combined will be described.

  FIG. 11 is a flowchart for explaining an example of a processing procedure executed by the mobile terminal according to the fourth embodiment. Steps S401 to S403 are the same as steps S101 to S103 in FIG.

  In step S404, when the movement detection unit 103 detects that the contact state of both the two contact points has been released (Yes in S404), the movement detection unit 103 ends the process of FIG. On the other hand, in a state in which the release of the contact state between the two contact points is not detected (No in S404), when the movement detection unit 103 detects the rotation of the two contact points (Yes in S405), step S105 in FIG. The subsequent processing is executed. That is, the character string to be copied or cut is stored in the character string storage unit 106 in accordance with the direction of rotation.

  In addition, in a state in which the release of the contact state between the two contact points is not detected (No in S404), the movement detection unit 103 detects the other rotation around one of the two contact points as the rotation axis. Then (Yes in S406), the processing after step S305 in FIG. 10 is executed. That is, the selection range is expanded or contracted.

  Further, in a state where the contact state of both of the two contact points is not detected (No in S404), when the movement detection unit 103 detects the slide of the contact point (Yes in S407), step S208 and subsequent steps in FIG. 8 are executed. The Note that the sliding contact point may be one point or two points. That is, the contact state of one contact point may or may not be released before the slide. However, considering the possibility of interference with the determination in steps S405 and S406, it is desirable that the contact state of one contact point is released and the slide is performed.

  As described above, the first to third embodiments do not necessarily have an exclusive or selective relationship, and can be performed simultaneously.

  In each of the above embodiments, the movement trajectory due to the rotation of the contact point may not be strictly an arc shape with respect to a certain center point, and may be linear. For example, in the first embodiment, the rotation of both contact points may be determined by the movement directions of both contact points being different. Here, the movement direction being different means that, for example, the direction of the vector indicating the movement locus of each contact point is different. Therefore, when both contact points rotate, the moving direction is different (for example, the opposite direction) even though the rotational directions look the same. Also for pinch-in and pinch-out, the moving directions of both contact points are different.

  In the first or third embodiment, the rotation of the other contact point in a state where one contact point is fixed may be determined by simply moving the other contact point. Also, the fixing of one contact point may not be required until the contact point is strictly fixed (the movement amount is 0). For example, when the amount of movement of the contact point is within a predetermined value, it may be determined that the contact point is fixed.

  In the second embodiment, the movement of two contact points in the same direction means, for example, that the directions of vectors indicating the movement trajectories are the same. However, the directions of the vectors need not be exactly the same. For example, the same direction may mean that the angle difference between the directions of the respective vectors is within a predetermined value.

  In each of the above embodiments, the mobile terminal 10 has been described as an example of an electronic device. However, the above embodiments are applied to electronic devices other than the mobile terminal as long as they can be input via a touch panel. Also good. In this case, the touch panel and the electronic device are not necessarily configured integrally.

  In each of the above embodiments, the two-point contact detection unit 101 is an example of a detection unit. The character string operation unit 105 is an example of an operation unit. The character string storage unit 106 is an example of a storage unit.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
