Description

  The present technology relates to a technology for selecting a range of text, and more particularly to a technology for supporting range selection by a drag operation of a pointing device.

  Conventionally, when a user edits text on a computer, for example, a text range may be selected by a drag operation of a pointing device such as a mouse or a pen. Specifically, in the case of a mouse, for example, a text range is selected by pressing the left button at the selection start point, moving the cursor while holding down the left button, and releasing the left button at the selection end point. .

For example, when performing range selection over a plurality of rows as shown in FIG. 12A, generally, the pointing device is moved from the selection start point to the selection end point as shown in FIG. 12B. Range selection.
Japanese Patent Laid-Open No. 9-101953

  However, in the above operation, the pointing device must be moved from the vicinity of one line end (the end of the line in FIG. 12B) to the vicinity of the opposite line end (the beginning of the line in FIG. 12B), The movement distance may be significantly longer than the width of the selection range. Therefore, there has been a problem that the selection operation becomes unnatural compared to the case where the selection range is within one line.

  Therefore, an object of the present technology is to provide a technology for enabling range selection by natural selection operation even when a character string to be range-selected extends over a plurality of lines.

  This text range selection processing method is a text range selection processing method in the case of selecting a range of the text by dragging with a pointing device with respect to the text displayed on the display unit. While selecting the range of the text in the display frame, according to the number of characters or the distance from the cursor position of the pointing device, the closest line end to the cursor position is specified as the nearest line end of the line to which the cursor belongs. A step of extracting a character string of a predetermined length from the head of the line opposite to the end of the nearest line or the end of the line, the line at the back of the line to which the cursor belongs, or the end of the line at the front of the line as the selected prediction text; The second display frame for displaying the selected predicted text is displayed in the selected predicted text. For comprises a step of displaying in the vicinity of the nearest row end range selection possible embodiments by the drag operation.

  Even when the character string to be range-selected extends over a plurality of lines, the range can be selected by a natural selection operation.

  First, an outline of an embodiment of the present technology will be described with reference to FIGS. 1 and 2. In the embodiment of the present technology, during the range selection by the drag operation of the pointing device, the closest to the end of the line is specified as the nearest line end from the beginning and end of the line to which the cursor of the pointing device belongs. When the head of the line is specified as the nearest line end, a character string of a predetermined length is extracted as the selected prediction text from the end of the line in the front line, and when the end of the line is specified as the nearest line end, A character string of a predetermined length is extracted from the beginning of the line as the selected prediction text. The selected predicted text display frame is displayed in the vicinity of the nearest line end in such a manner that the range can be selected for the selected predicted text.

  FIG. 1 shows an example when the end of a line is specified as the nearest line end. In the example of FIG. 1, a selected predicted text display frame 102 is displayed on the right side of the main text display frame 101. In the example of FIG. 1, the selected predicted text display frame 102 displays a character string extracted from the beginning of the line immediately below the line to which the cursor belongs as the selected predicted text.

  FIG. 2 shows an example when the head of a line is specified as the nearest line end. In the example of FIG. 2, a selected predicted text display frame 202 is displayed on the left side of the main text display frame 201. In the example of FIG. 2, the selected predicted text display frame 202 displays a character string extracted from the end of the line immediately above the line to which the cursor belongs as the selected predicted text.

  In the embodiment of the present technology, for example, when a range of a character string “computer” is selected, as shown in FIG. 1, the selection start point 1011 in the main text display frame 101 is selected in the selected predicted text display frame 102. An operation of dragging to the selection end point 1021 is performed. Thereby, the moving distance of the pointing device is not significantly longer than the width of the selection range, and the range can be selected by a natural selection operation. Hereinafter, processing of the text range selection processing device according to the embodiment of the present technology will be described.

  FIG. 3 shows a functional block diagram of a text range selection processing device according to an embodiment of the present technology. The text range selection processing device includes an operating system (OS) 1 and an application program 3 executed on the OS 1. Although not shown, the OS 1 detects an event related to the pointing device (for example, mouse click, cursor movement, drag start or end, etc.) and sends a message for notifying the event to the text application program 3. It has functions such as output. Since this function is the same as the conventional function, it will not be described further.

  The OS 1 includes a text range selection module 11 that performs basic processing related to text range selection. Specifically, the text range selection module 11 stores the drag start position as a selection start point related to range selection, stores the current cursor position as a selection end point related to range selection according to the movement of the cursor, Processing such as highlighting the character string from the selection start point to the selection end point is performed. Note that the processing related to text range selection is not different from the conventional processing and will not be described further.

  The application program 3 includes a selection prediction text generation unit 31, a selection prediction text display unit 33, a position specification unit 35, a position conversion unit 37, and a selection end point setting unit 39. The selection prediction text generation unit 31 receives a message of an event related to the pointing device from the OS 1 and specifies the beginning or end of the line to which the current cursor belongs as the nearest line end, or the main text (that is, in the main text display frame). A character string of a predetermined length from the displayed text) is extracted as the selected predicted text, or when the current cursor is in the selected predicted text display frame, the fact is notified to the position specifying unit 35. Perform the process. The selected predicted text display unit 33 displays a selected predicted text display frame including the selected predicted text extracted by the selected predicted text generation unit 31 in the vicinity of the nearest line end. In response to the notification from the selected predicted text generating unit 31, the position specifying unit 35 specifies the position indicated by the current cursor in the selected predicted text. The position conversion unit 37 calculates a character position in the main text corresponding to the position specified by the position specifying unit 35. The selection end point setting unit 39 sets the character position calculated by the position conversion unit 37 as the selection end point related to the range selection.

  Next, processing contents of the text range selection processing apparatus shown in FIG. 3 will be described with reference to FIGS. First, the OS 1 detects an event related to a drag operation (for example, drag start, cursor movement, drag end, etc.) (FIG. 4: Step S1). Then, the OS 1 acquires the current cursor position and temporarily stores it in the storage device (step S3). Then, the OS 1 outputs a message (including current cursor position information) for notifying the detected event to the application program 3.

  Then, the selected predicted text generation unit 31 of the application program 3 receives a message including the current cursor position information from the OS 1 and determines whether or not the current cursor is within the main text display frame (step S5). ). For example, if a library provided by the OS 1 is used, the coordinates of the main text display frame can be acquired. If the current cursor is not in the main text display frame (step S5: No route), the process proceeds to step S29 (FIG. 9) via the terminal C.

  On the other hand, when it is determined that the current cursor is within the main text display frame (step S5: Yes route), the selected predicted text generation unit 31 selects the current cursor from the beginning and end of the line to which the current cursor belongs. The one closer to the position of is identified as the nearest line end (step S7). For example, a character having a smaller number of characters may be specified as the nearest line end, and a character having a shorter distance may be specified as the nearest line end. In addition, since the character width of each character is not necessarily the same depending on the font and character size, it is preferable to use the distance as a determination criterion rather than the number of characters. For example, when a line feed code is inserted in the main text, the right end of the main text display frame is not the end of the line, but the position of the line feed code is the end of the line.

  And the selection prediction text production | generation part 31 judges whether the selection prediction text display frame is already displayed (step S9). When the selection prediction text display frame is already displayed (step S9: Yes route), the process proceeds to step S21 (FIG. 5) via the terminal B. On the other hand, if the selected prediction text display frame is not displayed (step S9: No route), the process proceeds to step S11 (FIG. 5) via the terminal A.

  Shifting to the description of FIG. 5, after the terminal A, the selected predicted text generation unit 31 determines whether the display start condition of the selected predicted text display frame is satisfied (FIG. 5: step S <b> 11). For example, if you want to display the selected predicted text display frame when the current cursor position approaches the nearest line end to some extent, the number of characters or the distance from the current cursor position to the nearest line end is the display start judgment threshold. The following condition may be set as the display start condition. In this case, as shown in FIGS. 6 and 7, when the number of characters or distance to the end of the nearest line exceeds the display start determination threshold (FIG. 6), the display of the selected prediction text display frame is not started and the nearest When the number of characters or the distance to the end of the line is equal to or less than the display start determination threshold (FIG. 7), the display of the selected predicted text display frame is started. Note that if it is desired to always display the selected predicted text display frame during the drag operation, the condition that the event detected in step S1 is the drag start may be set as the display start condition. Further, other conditions may be set as display start conditions.

  When it is determined that the display start condition of the selected predicted text display frame is not satisfied (step S11: No route), the processes of steps S13 and S15 described below are skipped, and the process proceeds to step S17.

  On the other hand, when it is determined that the display start condition of the selected predicted text display frame is satisfied (step S11: Yes route), the selected predicted text generation unit 31 is at the beginning or end of the line opposite to the nearest line end, A character string having a certain number of characters is extracted as a selected predicted text from the beginning of the line one line below the line to which the cursor belongs or the end of the line one line above (step S13). Specifically, when the end of the line is specified as the nearest end of the line, a character string having a certain number of characters is extracted as the selected predicted text from the beginning of the line immediately below the line to which the current cursor belongs. On the other hand, when the head of the line is specified as the nearest line end, a character string having a certain number of characters from the end of the line on the line immediately above the line to which the current cursor belongs is extracted as the selected predicted text. The fixed number of characters may be a predetermined number of characters or a fixed number of characters of one line length. Alternatively, the number of characters that can fit in the selection predicted text display frame may be used. Furthermore, any one may be selected according to the case. Then, the selected predicted text generation unit 31 outputs a display start instruction including the extracted selected predicted text to the selected predicted text display unit 33.

  Then, the selected predicted text display unit 33 receives the display start instruction from the selected predicted text generation unit 31, and displays the selected predicted text display frame in the vicinity of the nearest line end (step S15). For example, the selection prediction text display frame is displayed using a library provided by the OS 1. When the length of the selected predicted text is longer than the width of the selected predicted text display frame, the selected predicted text is displayed in multiple lines by folding back at the width of the selected predicted text display frame. For example, even if a line feed code is included in the selected predicted text, it is not necessary to make a line break at the position of the line feed code, and a line feed mark may be displayed at the line feed position. The selected predicted text display unit 33 stores the position of the nearest line end in the storage device as information for specifying which line end the selected predicted text display frame is displayed corresponding to. .

  If the cursor moves from the main text display frame to the selected predicted text display frame during range selection, the selected predicted text display frame becomes active, and the selected predicted text range can be selected in the selected predicted text display frame. It becomes. Such a technique can be realized by using a normal window technique.

  Thereafter, the text range selection module 11 of OS1 sets the position of the cursor stored in the storage device as the selection end point (step S17). Then, the text range selection module 11 performs the processing related to range selection as described above for the main text display frame (step S19). For example, the main text display frame is subjected to processing such as reverse-displaying the character string selected in the range. Then, the process ends.

  Next, a process when it is determined in step S9 (FIG. 4) that the selected prediction text display frame has already been displayed and the process proceeds to FIG. In FIG. 5, after the terminal B, the selected predicted text generation unit 31 determines whether the display end condition of the selected predicted text display frame is satisfied (step S21). For example, if you want to hide the selected prediction text display frame when the cursor position is far from the end of the nearest line, the number of characters or distance from the current cursor position to the end of the nearest line must be greater than the display end judgment threshold. Is set as the display end condition. The display end determination threshold value may be the same value as the display start determination threshold value, or may be a value different from the display start determination threshold value. If it is desired to hide the selected predicted text display frame at the end of the drag, a condition that the event detected in step S1 is the end of the drag may be set as the display end condition.

  When it is determined that the display end condition of the selected predicted text display frame is satisfied (step S21: Yes route), the selected predicted text generation unit 31 outputs a display end instruction to the selected predicted text display unit 33. And the selection prediction text display part 33 will erase | eliminate a selection prediction text display frame, if the display completion instruction | indication from the selection prediction text production | generation part 31 is received (step S23). And it transfers to the process of step S17, the process of step S17 and step S19 is implemented, and a process is complete | finished after that.

  On the other hand, when it is determined that the display end condition of the selected predicted text display frame is not satisfied (step S21: No route), the selected predicted text generation unit 31 determines that the nearest line end specified in step S7 (FIG. 4) is Then, it is determined whether it is the same as the nearest line end at the time of displaying the selected predicted text display frame currently being displayed (step S25). When it is determined that the identified nearest line end is the same as the nearest line end when the selected predicted text display frame currently displayed is displayed (step S25: Yes route), the process proceeds to step S17. Steps S17 and S19 are performed, and then the process ends.

  On the other hand, when it is determined that the identified nearest line end is not the same as the nearest line end at the time of displaying the currently selected selected predicted text display frame (step S25: No route), the selected predicted text generation unit 31. Outputs a display end instruction to the selected predicted text display unit 33. And the selection prediction text display part 33 will erase | eliminate a selection prediction text display frame once, if the display completion instruction | indication from the selection prediction text production | generation part 31 is received (step S27). And it transfers to the process of step S13, the process of step S13 thru | or step S19 is implemented, and a process is complete | finished after that.

  For example, if the position of the cursor moves from the position shown in FIG. 7 to the position shown in FIG. 8 during range selection, the position of the nearest line end changes before and after the movement. When the position of the nearest line end changes in this way, the selected predicted text display frame displayed before the movement is temporarily deleted by executing the processes of step S27, step S13, and step S15, and a new one is displayed. The selected prediction text display frame can be displayed near the end of the nearest line after moving.

  Shifting to the description of FIG. 9, after the terminal C, the selected predicted text generation unit 31 determines whether the current cursor is within the selected predicted text display frame (FIG. 9: step S29). If the current cursor is not within the selected predicted text display frame (step S29: No route), the process proceeds to step S17 via the terminal D, and the processes of step S17 and step S19 are performed. Thereafter, the process ends. To do.

  On the other hand, when it is determined that the current cursor is within the selected predicted text display frame (step S29: Yes route), the selected predicted text generating unit 31 outputs the current cursor position information to the position specifying unit 35.

  Then, the position specifying unit 35 receives the current cursor position information from the selected predicted text generating unit 31, and specifies the end position in the selection range of the selected predicted text based on the current cursor position information (step S31). . Specifically, if the end of the line is the end of the nearest line, specify the number of the current cursor from the beginning of the selected prediction text, and if the end of the line is the end of the nearest line, Specify what character the cursor is pointing to from the end of the selected prediction text. For example, when the cursor is at the position shown in FIG. 10, the position of the second character from the beginning is specified as the end position. Then, the position specifying unit 35 outputs the end position information to the position converting unit 37. Here, the following description will be given assuming that the position of the s-th character is specified as the end position.

  Then, the position conversion unit 37 receives the end position information from the position specifying unit 35, and calculates the character position u in the main text corresponding to the end position based on the position of the nearest line end and the end position. (Step S33). Specifically, if the end of the line is the end of the nearest line, the character at the end of the line is the (t-1) th character in the main text, and the first character of the selected prediction text is the tth character in the main text. Then, the character position u can be calculated by u = t + s−1. On the other hand, when the beginning of the line is the nearest line end, if the character at the beginning of the line is the (t + 1) -th character in the main text and the last character of the selected prediction text is the t-th character in the main text, u = t The character position u can be calculated by -s + 1. Then, the position conversion unit 37 outputs the calculated character position u to the selection end point setting unit 39.

  The selection end point setting unit 39 receives the character position u from the position conversion unit 37, and sets the character position u as the selection end point (step S35). And it transfers to the process of step S19 via the terminal E, the process of step S19 is implemented, and a process is complete | finished after that.

  By performing the processing as described above, it is possible to perform range selection by a drag operation as shown in FIG. 1 even when a character string to be range-selected extends over a plurality of lines. That is, the moving distance of the pointing device does not become much longer than the width of the selection range, and the range can be selected by a natural selection operation.

  Although one embodiment of the present technology has been described above, the present technology is not limited to this. For example, the functional block diagram of the text range selection processing device described above does not necessarily correspond to the actual program module configuration. For example, the processes of the selected predicted text generation unit 31, the selected predicted text display unit 33, the position specification unit 35, the position conversion unit 37, and the selection end point setting unit 39 described above can be implemented as functions of the OS1. .

  In the above description, the drag operation toward the end of the line has been described as an example, but the present invention can also be applied to a drag operation toward the start of the line.

  In the above description, the case where the text is written horizontally is described as an example, but the present invention can also be applied to the case where the text is written vertically. If the text is written vertically, the selected predicted text display frame may be displayed above or below the main text display frame.

  Further, for example, in FIG. 1, the selected predicted text display frame 102 is displayed connected to the main text display frame 101, but it is not always necessary to display the selected predicted text display frame 102. For example, as shown in FIG. 11, the selected predicted text display frame 1102 may be displayed separated from the main text display frame 1101 by a certain distance. For example, when the range of the main text is selected over a plurality of lines, an operation of dragging along the main text display frame 1011 in the vertical direction may be performed. If the main text display frame 1101 and the selected predicted text display frame 1102 are separated from each other for a certain period, the above operation can be distinguished from the operation for selecting a range of the selected predicted text.

  In the above example, the selection prediction text display frame is displayed / hidden according to the number of characters or the distance from the current cursor position to the end of the nearest line. However, apart from the drag operation, some buttons are used. It is also possible to adopt a mechanism that switches between display / non-display of the selected predicted text display frame by pressing the button. Note that the selection prediction text display frame may be always displayed near the end of the nearest line.

  In the above, the direction of the drag operation is not taken into consideration, but it may be determined whether or not to display the selection prediction text in consideration of the direction of the drag operation. For example, for the drag operation toward the end of the line, it is possible to adopt a configuration in which the selected prediction text display frame is displayed only when the end of the line is specified as the nearest line end.

  The present embodiment can be summarized as follows.

  This text range selection processing method is a text range selection processing method in the case of selecting a range of the text by dragging with a pointing device with respect to the text displayed on the display unit. While selecting the range of the text in the display frame, according to the number of characters or the distance from the cursor position of the pointing device, the closest line end to the cursor position is specified as the nearest line end of the line to which the cursor belongs. A character string of a predetermined length is extracted as a selected prediction text from the line end specifying step and the beginning or end of the line opposite to the nearest end of the line, starting from the beginning or end of the line after the line to which the cursor belongs. A selection prediction text extraction step and a second display of the selection prediction text The 示枠, and a selection predictive text displaying step of displaying in the vicinity of the nearest row end range selection possible embodiments according to the drag operation for the selected predictive text.

  In this way, for example, even if there is a selection end point near the end of the line opposite to the nearest line end, the character string near the end of the opposite line is selected as the selection prediction text and the range is selected near the end of the nearest line. Since it is displayed in a possible manner, the range can be selected without moving the pointing device to the vicinity of the row end on the opposite side. That is, the moving distance of the pointing device does not become much longer than the width of the selection range, and the range can be selected by a natural selection operation.

  In addition, when the range selection is made to the end of the nearest line in the first display frame and the range selection is made for at least a part of the selected prediction text in the second display frame, the end position in the selection range of the selection prediction text is specified. Calculating a character position in the text corresponding to the end position from the step, the specified end position and the position of the nearest line end, and setting the calculated character position as a selection end point for text range selection A step may be further included. In this way, the part selected in the second display frame can be reflected in the first display frame.

  Furthermore, after the line end specifying step described above, a step of determining whether the number of characters or the distance from the cursor position to the nearest line end is equal to or less than a predetermined display start determination threshold value may be further included. Then, when it is determined that the number of characters or the distance from the cursor position to the end of the nearest line is equal to or less than the display start determination threshold value, the processing after the selection predicted text extraction step described above may be performed. Further, after displaying the second display frame, a step of determining whether the number of characters or distance from the cursor to the nearest line end is equal to or greater than a predetermined display end judgment threshold, and the number of characters or distance from the cursor to the nearest line end is A step of deleting the second display frame may be further included when it is determined that the display end determination threshold is exceeded. In this way, for example, the second display frame is displayed when the cursor position approaches the nearest line end, and the second display frame is hidden when the cursor position moves away from the nearest line end. be able to.

  Furthermore, in the selection prediction text display step described above, the second display frame may be displayed while being separated from the first display frame by a certain distance. In this way, by displaying the second display frame while being separated from the first display frame by a certain distance, it is possible to appropriately distinguish a predetermined operation on the first display frame and a drag operation on the second display frame. There is no loss of operability.

  A program for realizing the text range selection processing device together with hardware can be created. The program can be a storage medium or storage device such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, or a hard disk. Stored in The intermediate processing result is temporarily stored in a storage device such as a main memory.

  As shown in FIG. 13, the text range selection processing device includes a memory 2501 (storage unit), a CPU 2503 (processing unit), a hard disk drive (HDD) 2505, a display control unit 2507 connected to the display device 2509, and a removable device. A drive device 2513 for the disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network are connected by a bus 2519. Application programs including the OS and the Web browser are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. If necessary, the CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 to perform necessary operations. Further, data in the middle of processing is stored in the memory 2501 and stored in the HDD 2505 if necessary. Such a computer realizes various functions as described above by organically cooperating hardware such as the CPU 2503 and the memory 2501 described above with the OS and necessary application programs.
