Description

[0001]
[Industrial application fields]
The present invention relates to a method for moving a cursor indicating the position of information displayed on a display device, and more particularly to a method for moving a character cursor using a pointing device such as a mouse when scrolling a screen.
[0002]
[Prior art]
Of the information displayed on the display screen of the display device, a cursor is used to indicate the position of the information of interest or the position of information to be processed next. As a method of moving this cursor In addition to automatically moving the current position or the next position to be processed by the program, the character cursor movement keys on the keyboard (for example, arrow keys (→, ←, ↑, ↓) )) Point to the position of interest with a pointing cursor (for example, a mouse cursor shown on the screen with an arrow) with a pointing device such as a mouse, or an icon (pictogram) provided on the screen. There is a method to move the character cursor.
[0003]
Although the cursor can be moved using a pointing device, the character cursor can be moved to that position by pointing any information with the pointing cursor. In addition, there is a problem in that there is inconvenience in operation because the next cursor position is pointed to by a pointing device.
[0004]
As an example of a technique for solving such a problem, a character cursor in a character record area of a figure being edited in a document editing process is operated by key operation or pointing as in the technique disclosed in Japanese Patent Laid-Open No. 5-334289. The pointing cursor is usually interlocked with the character cursor as in the case of moving to the character record position of a desired figure by operation of the device or the technique disclosed in Japanese Patent Laid-Open No. 6-149478. There is a method of moving a cursor using a pointing device configured to move from a cursor and return to the cursor position when the operation of the pointing device is completed.
[0005]
On the other hand, in order to display a portion that is not displayed on the screen on the screen of the display device (for example, the editing screen of the word processor), a method of scrolling the screen by pressing an arrow key on the keyboard, Buttons 71 to 74 as illustrated in FIG. 7 are provided on the screen, and the user operates the pointing device to point (point to) one of the buttons 71 to 74 with the pointing cursor, and the selected button Scrolling the screen in the direction meaning, or a switch (scroll bar 82) that can be moved by operating the pointing device on the frame of the window 81 as shown in FIG. 8, and scrolling by operating the pointing device There is a method of scrolling in an arbitrary direction by moving the bar 82.
[0006]
[Problems to be solved by the invention]
Among the above-described conventional techniques, the cursor movement method when scrolling the screen by operating the pointing device is such that the cursor moves like the button 71 or the scroll bar 82 from the position of the information currently focused on the line of sight. Therefore, it is necessary to operate the pointing device while moving to the area of the movement mark that has a meaning for the purpose, and to move or move the desired movement mark with the pointing cursor. There was a problem with accompanying fatigue.
[0007]
In particular, when the displayed information (recognized character) is changed as in the correction screen of the character recognition device, the character cursor is moved by the pointing device when the candidate character is corrected. It is convenient because it can be specified and replaced with candidate characters, but it is necessary to move the pointing cursor to the mark part for moving the character cursor provided on the screen each time scrolling, so the recognition result must be scrolled. Each time a new recognition result has to be repointed, the confirmation process is interrupted, causing eyes to be tired and inefficient work efficiency.

A one-character image window for displaying the result (one character), 26 is a character cursor indicating the position of an arbitrary one of the recognition results.
[0022]
Hereinafter, based on FIG. 2 and FIGS. 3 to 5, the operation of the screen setting means, pointing area determination means, scroll means and cursor moving means in the image recognition apparatus 20 is taken as an example and the cursor moving method by the pointing device of the present invention is described. explain.
[0023]
2A and 3, the editing unit 90 first opens the base window 21 on the screen of the display 5 by the screen setting unit 91 (S 101), and then superimposes it on the base window 21 to recognize the result. The display window 22 is opened (S102). In FIG. 3, the original image window 23 is opened after the recognition result display window 22 is opened, the character having the highest similarity among the recognition result candidate characters is displayed in the recognition result display window 22, and the first character of the recognition result is displayed. Although the cursor is displayed at (the leftmost character position on the first line), the description is omitted because it is not directly related to the description of the present invention.
[0024]
The editing means 90 uses the screen setting means 91 to correspond to the first to fourth pointing areas 22 (upper, lower, left, right) having a predetermined width along the inside of each of the upper, lower, left and right sides of the recognition result display window 22. Are set as the first, second, third and fourth pointing areas respectively) (step S103), and the recognition result display window 22 corresponds to one original in the image data storage unit 11 via the character recognition unit 8. All or part of the recognized characters are displayed in the row direction and the column direction (step S104).
[0025]
When the display of the initial correction screen is finished, the editing unit 90 waits for an instruction from the key input unit 3 or the pointing device 4 via the input device management unit 6. In this embodiment, the correction processing unit 9 corrects / edits display data such as the cursor moving means 94, the character overwriting / inserting by kana-kanji conversion, the replacing means 95 by the candidate character, the character deleting means, etc. as the editing means 90 as described above. The candidate character replacement means 94 is pointed to (pointed to) any recognition result by the pointing device 4, and the character cursor 26 moves to the pointed recognition result position. Then, the one-character image window 24 displaying the candidate characters is opened, and the character device can be replaced with an arbitrary candidate character by a pointing operation by the pointing device 4.
[0026]
FIG. 2B is a flowchart of processing by the pointing area determination unit 92 of the editing unit 90 when the user operates the pointing device 4, and the display of the initial correction screen described in FIG. Thereafter, when the user performs a correction operation on the recognition result displayed in the recognition result display window 22, the pointing area determination unit 92 is activated by starting the execution by operating the pointing device 4 as one of the editing units. .
[0027]
In FIG. 2B, when the user operates the pointing device 4, the pointing area determination unit 92 determines whether or not the location pointed to by the pointing cursor (not shown) is the pointing area 22 (step S201).
If the pointing area 22 is not pointed, the process proceeds to another process, for example, a process different from scrolling such as correction of the recognition result by the candidate character (step S202).
[0029]
If the pointing area 22 is pointed, it is determined whether the pointing area 22 is pointed up, down, left, or right (S203), and the pointing area (first pointing area) along the upper side of the recognition result display window 22 is determined. In the case of the pointing area (second pointing area) along the lower side of the recognition result display window 22, the downward cursor movement process is executed (S205). In the case of a pointing area (third pointing area) along the left side of the result display window 22, left cursor movement processing is executed (S206), and a pointing area (fourth area) along the right side of the recognition result display window 22 is executed. Pointing area), move the cursor to the right Row (S207).
[0030]
As described above, the pointing area determination unit 92 activates the up / down / left / right cursor moving means corresponding to the position (up / down / left / right) of the pointing area 22 provided in the edge of the top / bottom / left / right sides of the recognition result display window 22. To do. Here, in the present embodiment, the cursor activation means is not activated even when a portion belonging to two positions in the pointing area 22, that is, the four corners of the recognition result display window 22 is pointed, but each of the four corners is not activated. You may comprise so that another meaning (function) may be given about.
[0031]
FIG. 2 (c) shows an example in which the right cursor movement process is selected by the pointing area determination means 92 in FIG. 2 (b) among the operations of the scroll means 93 and the cursor movement means 94. 5 is a flowchart showing the operation of a moving means 94. Hereinafter, FIG. 2C together with FIG. 4 and FIG. 5 will explain the operation of the scroll means 93 and the cursor moving means 94.
[0032]
When the character cursor 26 is positioned at “NO”, which is the recognition result displayed on the right side of the first line among the recognition results displayed in the recognition result window 22 as shown in FIG. In order to confirm the next recognition result of the cursor 26 (that is, the recognition result subsequent to “no” which is not displayed on the screen), the pointing device 4 is operated by operating the pointing device 4 to the right of the “no”. When the pointing area (4) is pointed by the pointing cursor, the right cursor movement process (S207) is started through steps S201 and S203 of FIG.
[0033]
In FIG. 2C, the cursor moving means determines whether or not there is a next recognition result of the character cursor 26 (S301). In this embodiment, if the position of the character cursor 26 is at the end of the line and there is no recognition result on the right side, the right cursor movement process is terminated without doing anything, but this is not a limitation. For example, the character at the beginning of the next line You may comprise so that the cursor 26 may be moved.
[0034]
If there is a next recognition result on the right side of the character cursor 26, it is determined whether or not it is displayed in the recognition result window 22 (S302). If it is displayed, the process proceeds to step S304. If the next recognition result is not displayed on the right side of the character cursor 26 as shown in FIG. 4, it is displayed on the recognition result window 22 by the scroll means 93. After the recognition result column is scrolled to the left by one character (S303), the cursor moving means 94 moves the character cursor 26 to the position of the next recognition result “table” displayed as a result of scrolling as shown in FIG. Move (S304).
[0035]
In this embodiment, the scroll means 93 is configured to scroll the recognition result column displayed in the recognition result window 22 in step S303 leftward by one character. However, the point cursor is in the pointing area. It may be configured to scroll by one character in proportion to the time, or may be configured to scroll by one character in proportion to the time during which the operation button of the pointing device 4 is pressed.
[0036]
As mentioned above, when the pointing result is pointed sequentially with the pointing device and correction is performed using candidate characters, the recognition result is pointed sequentially to the right end of the recognition result screen and the next recognition result is displayed. However, if the confirmation is completed up to the right end of the recognition result display window 22 by the setting of the pointing area 22, the pointing area 4 on the right side is pointed with the pointing device 4, and the recognition result screen is scrolled. Then, the cursor moving means is activated and the cursor is positioned at the next character position. Thus, the provision of the pointing area eliminates the trouble of pointing the pointing device to the left and right, and simplifies the operation of the pointing device.
[0037]
Further, for example, when it is desired to refer to the candidate character of the recognition result “table” with the character cursor 26 in FIG. This can be realized by slightly shifting to the left and pointing to the recognition result “table”.
[0038]
2C, FIG. 3 and FIG. 5, the cursor movement process in the right direction has been described, but the cursor movement process in the left direction is the direction in the scroll (S303) and cursor movement (S304) processes. It is only necessary to reverse the left and right, and for the cursor movement process in the vertical direction, when the character cursor is on the uppermost line or the lowermost line, scrolling and moving in the column direction are performed in the scrolling (S303) and cursor movement (S304) processes. Instead of scrolling and moving in the direction, the position of the character cursor need only be the same or just moved to the beginning of the line, so the description of the cursor movement processing in the left and up and down directions will be omitted.
[0039]
As described above, according to the present invention, even when the next focused character is not displayed on the screen, the screen can be scrolled and the cursor can be moved with little effort, and the next processing can be performed with less suggestive movement. The user's eyes are less fatigued.
[0040]
In the present embodiment, the pointing area having a predetermined width is provided along the side of the window. However, the pointing area is not limited to the window and may be provided along the side of the area surrounded by the frame on the screen. In addition, the number of regions surrounded by frames on the window or the screen is not limited to one, and may be plural.
It is also possible to construct a frame on the screen by the pointing area and display an information group (for example, a character string) inside the frame.
[0042]
【The invention's effect】
As described above, according to the present invention, it is possible to minimize the movement of the pointing cursor when the display information is scrolled by providing the pointing area, so that the trouble of pointing the pointing device to the left and right is omitted. Can be simplified. Specifically, even when the next focused character is not displayed on the screen, the screen can be scrolled and the cursor can be moved with little effort, and the next processing can be performed with a small suggested movement. So there is little eye fatigue for the user.
