JP6249851B2 - INPUT CONTROL DEVICE, INPUT CONTROL METHOD, AND PROGRAM - Google Patents

Description

  The present invention relates to an input control device, an input control method, and a program for controlling an input operation via a touch panel during character input.

  With smart devices such as iPhone (trademark) and Android (trademark), touch operation or touch called flick operation is made into a character panel by using character input software (IME), and then the finger is moved and moved away from a certain distance and direction. Character input is possible (see, for example, Patent Document 1, Non-Patent Documents 1 and 2).

  In this character input, in order to perform an operation of inserting a character into a sentence, it is necessary to move the character input cursor by touching the input operation start position on the input form in which the character is input.

  In addition, the text range specification operation for character copying, etc. can be performed by performing an operation of shifting to the range specification operation such as long pressing the start position of the range or the position where the acquired word is described. ing. In the range designation operation, the range can be enlarged or reduced by touching a symbol indicating the range start position / end position and moving it to the left or right.

  In addition, there are character input screens that have left and right cursor keys in IME, and those that allow a character input cursor to be moved and a range specified by switching input to cursor display (see, for example, Patent Document 2). Furthermore, some terminals can be operated to move a character input cursor or specify a range with a hardware key.

<Functional configuration of input control device>
FIG. 1 is a diagram illustrating a functional configuration of an input control apparatus 100 according to an embodiment of the present invention. As illustrated in FIG. 1, the input control device 100 includes a display unit 110, a display control unit 120, a touch panel 130, an input operation determination unit 140, a touch position storage unit 150, an editing unit 160, an instruction position operation determination unit 170, an instruction position. A moving unit 180, a range setting unit 190, a position range storage unit 200, and a position range setting unit 210 are provided. Specifically, the input control device 100 is a smartphone, a tablet terminal, or the like.

  The display unit 110 is, for example, a liquid crystal display, and displays a screen in response to an instruction from the display control unit 120.

  The display control unit 120 displays a screen that displays at least a text and a text display area for displaying an instruction position indicating an operable position, and an input receiving area for receiving an input operation to the text display area. 110 is displayed. Here, the designated position indicates to the user the position for editing such as insertion and deletion of characters, and the start position and end position of the text selection range.

  The text display area is an area for displaying input text in a screen display of a text creation application (text editor, document creation software) or a web page display having a character input field in a web page display application (web browser). is there. The input receiving area is an area for receiving input of characters and symbols to be input to the text display area from a user, and displays, for example, a virtual keyboard on which keys such as symbols and characters are arranged.

  In addition, the display control unit 120 displays the results of the editing unit 160, the designated position moving unit 180, the range setting unit 190, and the position range setting unit 210 in the text display area of the screen displayed on the display unit 110.

  The touch panel 130 is disposed on the display surface of the display unit 110 and detects a touch input operation using a part of a human body such as a user's hand or finger, a touch pen, or the like. In the present embodiment, the touch panel 130 is a multi-touch sensor that can simultaneously detect a plurality of touch input operations, and the detection method includes a matrix switch method, a resistive film method, a surface acoustic wave method, an infrared method, an electromagnetic method, and the like. Any of an induction method, a capacitance method, or the like may be used.

  The touch panel 130 detects a touch input operation every predetermined time and acquires a touch position. Here, the touch position of the touch input operation is expressed as a coordinate value in the screen coordinate system, for example.

  In response to detecting one touch input operation (hereinafter referred to as a first touch operation) from a state where the touch panel 130 does not detect a touch input operation (hereinafter referred to as a non-touch state). The detected touch position of the first touch input operation (hereinafter referred to as the first touch position) is stored in the touch position storage unit 150.

  Based on the number of touch positions received from the touch panel 130 after detecting the first touch input operation, the input operation determination unit 140 determines whether the touch input operations detected simultaneously by the touch panel 130 are singular or plural. To do. That is, it is determined whether only the first touch input operation is detected or whether another touch input operation is detected together with the first touch input operation.

  When the number of detected touch positions is singular, that is, after the first touch input operation is detected and the first touch input operation is canceled without any other touch input operation, the input operation determination unit 140 displays the text display area. Judged to be a text editing operation. On the other hand, when the number of detected touch positions is plural, that is, when another touch input operation is detected together with the first touch input operation, the input operation determination unit 140 performs the operation with respect to the indicated position displayed in the text display area. It is determined that the designated position operation.

  The editing unit 160 specifies the input content based on the touch position acquired by the touch panel 130 and the movement distance and direction from the start position of the touch input in response to the text editing operation determined by the input operation determination unit 140. Edit the sentence based on the indicated position.

  Specifically, the editing unit 160 first specifies a character or process set in advance corresponding to the position of the touch operation included in the operation information. When a preset character is specified, the specified character is inserted at the indicated position displayed in the character display area. Further, when a preset process, for example, a deletion process is specified, one character before the indicated position displayed in the character display area is deleted.

  When the input operation determination unit 140 determines that the instruction position operation is an instruction position operation, the instruction position operation determination unit 170 determines the touch positions of a plurality of touch input operations detected by the touch panel 130, excluding the first touch input operation, as the second touch position. , And the third touch position are stored in the touch position storage unit 150, respectively. Next, the designated position operation determination unit 170 determines whether the plurality of touch input operations detected on the touch panel 130 are designated position change operations or selection range change operations.

  The instruction position operation determination unit 170 determines that the selection range change operation is at least one touch input operation detected by the touch panel 130 while at least one of the plurality of touch input operations is continued. This is a case in which the amount of change is greater than or equal to a predetermined threshold.

  Here, the change amount of the touch input operation is, for example, the movement distance of the touch position, and the threshold value is a movement distance that divides whether the touch input operation is a tap operation or a slide operation. Note that the threshold value is not 0 but is set to a value slightly larger than 0. Even if the user performs a tap operation as a touch input operation, it can be determined as a tap input operation even if the touch position moves because the hand shakes or the hand slips due to sweat, etc. Because.

  Therefore, the indication position operation determination unit 170 is a case where at least one touch input operation detected by the touch panel 130 is a slide operation while at least one touch input operation among a plurality of touch input operations is continued. The selection range changing operation is determined.

  For example, when the touch panel 130 detects two touch input operations, one touch input operation is continued at the same position, and the other touch input operation is a slide operation moved by a distance equal to or greater than a threshold value, The position operation determination unit 170 determines that the operation is a selection range change operation. In addition to the other touch input operations, even when one touch input operation is a slide operation moved by a distance equal to or greater than the threshold, the indication position operation determination unit 170 determines that the operation is a selection range change operation.

  The indication position operation determination unit 170 determines that the indication position change operation is performed for all the touch input operations detected by the touch panel 130 while at least one of the plurality of touch input operations is continued. This is a case where the amount of change is less than a predetermined threshold value.

  For example, when the touch panel 130 detects two touch input operations, one touch input operation is continued at the same position, and the other touch input operation is a tap input operation, both the two touch input operations are changed. Is less than the threshold value, the designated position operation determination unit 170 determines that the designated position change operation is performed. In addition, when the touch panel 130 detects three touch input operations, one touch input operation is continued at the same position, and the other two touch input operations are tap input operations, or two touch input operations are at the same position. If the remaining touch input operation is a tap input operation, the designated position operation determination unit 170 similarly determines that the designated position change operation is performed.

  The designated position operation may be either the designated position changing operation or the selection range changing operation. In this case, the instruction position operation determination unit 170 that determines the instruction position change operation or the selection range change operation is not necessary, and the input operation determination unit 140 determines whether the sentence editing operation or the instruction position change operation or the sentence editing operation. It is determined whether the operation or the selection range changing operation.

  The instruction position moving unit 180 is detected by the touch panel 130 while at least one touch input operation among a plurality of touch input operations is continued when the instruction position operation determination unit 170 determines that the instruction position is changed. The designated position is moved in response to the tap input operation.

  Specific instruction position change processing will be described with reference to FIG. 2 by taking as an example a case where there are two touch input operations detected by the touch panel 130. Note that the two touch input operations include a first touch input operation and a second touch input operation performed after the first touch input operation. May be. Moreover, it is set as the instruction | indication position change process with respect to a horizontal writing.

  First, in step S101, the pointing position moving unit 180 determines whether one of the two touch input operations has been released. If it is determined that one has been released (YES), the process proceeds to step S102. On the other hand, if it is determined that both have been released (NO), the process ends. The case where both of the two touch input operations are not canceled and the second touch input operation is a long tap operation will be described later.

  Next, in step S <b> 102, the designated position moving unit 180 determines whether the second touch input operation is released. If it is the second touch input operation that has been released, the process proceeds to step S103. On the other hand, if it is not the second touch input operation that has been released, the process proceeds to step S107. To proceed.

  Next, in step S <b> 103, the designated position moving unit 180 refers to the touch position storage unit 150 and compares the magnitude relationship between the x coordinate of the first touch position and the x coordinate of the second touch position. If the x coordinate of the first touch position is smaller than the x coordinate of the second touch position, the process proceeds to step S104. On the other hand, if the x coordinate of the first touch position is greater than or equal to the x coordinate of the second touch position. Advances the process to step S105. In the case of vertical writing, y coordinates are compared.

  Next, in step S104, the designated position moving unit 180 determines the moving direction of the designated position to the right because the second touch position is located to the right of the first touch position. In the case of vertical writing, since the second touch position is located above the first touch position, the moving direction of the designated position is determined upward.

  Next, in step S105, the designated position moving unit 180 determines the moving direction of the designated position to the left because the second touch position is located to the left of the first touch position. In the case of vertical writing, since the second touch position is located below the first touch position, the movement direction of the designated position is determined downward.

  Next, in step S106, the designated position moving unit 180 moves the designated position by the number of unit characters per preset tap input operation in the moving direction determined in step S104 or S105. For example, when the number of unit characters is one character, the designated position moves by one character. When there are a plurality of second touch input operations, for example, when there are three, the designated position moving unit 180 judges that the tap input operation is three times and moves the designated position by the number of unit characters × 3 minutes.

  Next, in step S107, the indication position moving unit 180 sets the second touch operation as the first touch operation in response to the release of the first touch operation, and performs a touch at the touch position of the new first touch operation. The first touch position in the position storage unit 150 is updated. By this update, even if the movement operation is excessively performed, the operation to return to the opposite side can be naturally performed.

  When the second touch input operation is a long tap input operation, the pointing position moving unit 180 determines that the tap input operation has been detected every predetermined time after a predetermined time has elapsed since the start of the long tap input operation. Each time a determination is made, the number of unit characters per one tap input operation and the indicated position are moved. For example, when the touch position is set to be detected every two seconds when the touch time is 6 seconds or longer, the pointing position moving unit 180 is set to the second touch input operation. It is determined that the tap operation after 6 seconds has elapsed since the start of the touch is performed once, and then it is determined that the tap input operation is performed once every 2 seconds until the touch ends.

  The range setting unit 190 is detected by the touch panel 130 while at least one touch input operation among the plurality of touch input operations is continued when the instruction position operation determination unit 170 determines that the selection range is changed. The selected range of text is set according to the slide operation.

  A specific selection range changing process will be described with reference to FIG. 3 using an example in which there are two touch input operations detected by the touch panel 130. Note that the two touch input operations include a first touch input operation and a second touch input operation performed after the first touch input operation. May be. In addition, the selection range changing process is performed for a horizontally written sentence.

  First, in step S <b> 201, the range setting unit 190 determines whether there is a touch input operation that has moved more than a unit movement distance in two touch input operations. If it is determined that there is a touch input operation that has moved more than the unit movement distance, the process proceeds to step S202. On the other hand, if it is determined that there is no touch input operation that has moved more than the unit movement distance, the process proceeds to step S210. Proceed. Here, the unit movement distance is a movement distance of the touch position of the touch input operation necessary for changing the start range or the end range of the selection range by one character, and is set in the range setting unit 190. Yes.

  Next, in step S202, the range setting unit 190 identifies a touch input operation that has moved by a unit moving distance or more. In this example, of the two touch input operations, a touch with a movement of a unit moving distance or more is hereinafter referred to as a movement input operation, and the other touch input operation is hereinafter referred to as a fixed input operation. Process. Note that if the touch input operation that is a fixed input operation is accompanied by a movement that exceeds the unit movement distance, that is, if the movement that exceeds the unit movement distance is involved in both touch input operations, the touch is designated as a movement input operation. On the other hand, that is, the touch input operation that is the movement input operation is set as a fixed input operation, and this processing described below is similarly performed.

  Next, in step S203, the range setting unit 190 selects one from the touch input operations specified in step S202.

  Next, in step S <b> 204, the range setting unit 190 refers to the touch position storage unit 150 and compares the magnitude relationship between the x coordinate of the fixed input operation and the x coordinate of the movement input operation. If the x coordinate of the fixed input operation is smaller than the x coordinate of the movement input operation, the process proceeds to step S205. On the other hand, if the x coordinate of the fixed input operation is greater than or equal to the x coordinate of the movement input operation, step S206 is performed. Proceed with the process. In the case of vertical writing, y coordinates are compared.

  Next, in step S205, the range setting unit 190 determines the change target to be the end range of the selection range because the movement input operation is located to the right of the fixed input operation. In the case of vertical writing, since the movement input operation is located above the fixed input operation, the change target is determined as the start range of the selection range.

  Next, in step S206, the range setting unit 190 determines that the change target is the start range of the selection range because the movement input operation is located to the left of the fixed input operation. In the case of vertical writing, since the movement input operation is positioned below the fixed input operation, the change target is determined as the end range of the selection range.

  Next, in step S207, the range setting unit 190 calculates the movement distance calculated by subtracting the initial position of the movement input operation stored in the touch position storage unit 150 from the current position of the movement input operation, the unit movement distance, The number of characters to be moved is determined as the movement range of the start range or end range. At this time, the range setting unit 190 updates the initial position of the movement input operation stored in the touch position storage unit 150 with the current position of the movement input operation.

  Next, in step S208, when the range setting unit 190 determines that the change target is the end range of the selection range in step S205, the designated range is the start range and end range, and the end range is determined in step S207. Move the range and set the range enclosed by the start range and end range. When the movement distance is a positive value, the end range is expanded to the right, and when the movement distance is a negative value, the end range is decreased to the left.

  In addition, when the change setting unit 190 determines that the change target is the start range of the selection range in step S206, the range setting unit 190 moves the start range by the movement range determined in step S207 using the designated position as the start range and end range. Set the range surrounded by the start range and end range. When the movement distance is a positive value, the start range is expanded to the left, and when the movement distance is a negative value, the start range is decreased to the right.

  Next, in step S209, the range setting unit 190 determines whether all the touch input operations specified in step S202 have been processed. If all touch input operations specified in step S202 have been processed, the process proceeds to step S210. If all touch input operations specified in step S202 have not been processed, the process returns to step S203.

  Next, in step S210, the range setting unit 190 determines whether one of the two touch input operations has been released. If one of the touch operations is released, the process ends. On the other hand, if neither of the two touch operations is released, it is determined that the selection range changing operation is continuing, and the process proceeds to step S201. To return.

  The position range storage unit 200 stores the position of the designated position in response to the designated position moving unit 180 moving the designated position. Each time the designated position is moved, the position of the designated position stored in the position range storage unit 200 is updated. Further, the position range storage unit 200 stores the start position and end position of the range in response to the range set by the range setting unit 190. Each time a range is set, the start position and end position of the range stored in the position range storage unit 200 are updated. The position range storage unit 200 inserts characters into the designated position, deletes characters before or after the designated position, and selects a range according to the input operation judging unit 140 determining that the text editing operation is performed on the text display area. After executing the text editing process such as overwriting, cutting, copying, etc., the stored position of the indicated position and the start position and end position of the range are deleted.

  The position range setting unit 210 sets the stored position or selection range of the indicated position in the display control unit 120 when the position range or selection range of the specified position is stored in the position range storage unit 200. The text is displayed in the text display area in the unit 110. Thereby, even if the designated position operation is once ended, the designated position can be continuously changed or the selection range can be changed.

  Then, in response to a tap input operation performed by the finger 42 while the finger 41 is being touched, the input control device 100 determines that the operation is a pointing position change operation. Next, since the finger 42 that performed the tap input operation is on the left side with respect to the finger 41 that continues to touch, the input control device 100 determines that the movement direction of the designated position 30 is to the left of the current designated position 30. The direction is determined, and the indicated position 30 is moved to the left by the number of unit characters per tap operation.

  When the number of unit characters is one, the tap operation with the finger 42 is repeated four times, and the indicated position 30 is moved between “ha” and “tooth” as shown in FIG. Then, the user can correct by releasing the finger 41 and touching the “,” key and inputting “,” between “ha” and “teeth”.

  Note that if the tap operation is repeated five times and the indicated position 30 has moved between “day” and “ha”, the finger 42 at the finger position as shown in FIG. While touching, the finger 41 is released, and a tap input operation is performed once with the finger 41. Accordingly, since the finger 41 that has performed the tap input operation is on the right side of the finger 42 that is continuously touching, the designated position 30 is moved to the right by one character, and the designated position 30 is “ha” and “ Move between "teeth".
