Description

DETAILED DESCRIPTION [Overview] This is a control method for improving cursor movement on a screen of a display device that displays various windows.

The cursor movement control is performed by the window attribute by determining the movement amount on the screen in response to the movement amount designation input by the operator for moving the cursor by the movement ratio specified by the window attribute indicating the type of window. Make it selectable.

With this method, it is possible to automatically select an appropriate cursor movement method according to the type of display information in the window determined by the window attribute, and facilitate the operator's work.

[Industrial application field]

The present invention relates to a method of controlling movement of a cursor on a screen of a display device that displays various windows.

In a display device that displays information on a screen such as a so-called CRT display device, a so-called window is used when data in a plurality of different files and the like are simultaneously displayed on one screen.

Further, in order to edit the display of the screen, etc., a cursor displayed on the screen is used as a means for designating a position on the screen, and in order to input a designation for moving the cursor to a required position, For example, an input device called a mouse is used.

[Conventional technology]

 FIG. 2 shows a configuration example of the display device.

The processing device 1 receives input information such as commands and data from the input unit 2 and outputs required display information to the display unit 3.

The input unit 2 includes, for example, a keyboard 4 and a mouse 5, and the display unit 3 includes, for example, a CRT display device.

In the processing device 1, the input control unit 6 receives the information input from the input unit 2, and passes the received information to the window management unit 7 and the cursor control unit 8 depending on the type of information.

The window management unit 7 opens a window according to the designation information that is input and forms a control link between each window and the associated data processing unit 9. In addition, the opened window is controlled to be displayed at a designated position on the screen of the display unit 3 via the output control unit 10.

Information input from the input unit 2 under a predetermined condition and information output from the related data processing unit 9 are displayed in each window.

FIG. 3 is a view for explaining an example of a window display on the screen, and rectangular areas on the screen shown by 20 and 21 in FIG. 3 (a) are windows.

When the areas overlap with each other as in the case of the figure, for example, the window having the cursor (indicated by a + shape in the figure) is displayed in the foreground as a so-called active window.

When the window management unit 7 identifies that the current position of the cursor received from the cursor control unit 8 has moved from the window 20 to the window 21, for example, FIG.
Change to the screen display state such as.

In the window, for example, a window for linking with a data processing unit 9 for processing only character information, such as the window 20, for displaying only characters, and a data processing unit for performing graphic processing as in the example of the window 21. There is a window attribute such as a window for displaying a graphic by vector type graphic data linked with 9, and the former is called a character type window and the latter is called a vector type window.

The cursor control unit 8 controls the output control unit 10 so as to display a cursor at an appropriate initial position on the screen, receives cursor movement designation information from the input unit 2 via the input control unit 6, or manages windows. When a cursor movement instruction is received from the section 7, the cursor display position on the screen is moved accordingly. Also, the current position of the cursor can be notified to the window management unit 7.

As is known in the art, when the operator of the input unit 2 moves the mouse 5 on a suitable horizontal surface of a table, the amount of movement is detected to detect, for example, an appropriately set orthogonal axis direction on the table surface. The input device has a function of generating a predetermined movement signal for each movement of a certain distance.

This movement signal is input to the cursor control unit 8 via the input control unit 6. The cursor control unit 8 receives the movement signal from the mouse 5
The distance and direction of movement of the mouse 5 are identified, and only the distance on the screen (for example, the distance represented by the number of screen display dots) converted by multiplying the moving distance value of the mouse 5 by a certain moving ratio,
The cursor display is controlled to move in a predetermined direction corresponding to the moving direction of the mouse 5 on the screen.

To specify the position on the screen with the cursor,
The operator moves the cursor to a desired position by moving the mouse 5, and then, for example, presses a push button provided on the mouse 5 to generate a position designation signal,
When the cursor control unit 8 receives this signal, it notifies the window management unit 7 of the current position of the cursor, and the window management unit 7 receives the current position as a parameter of a command separately designated from the input unit 2, Perform the required processing.

[Problems to be Solved by the Invention]

As described above, the position on the screen can be displayed in the unit of the screen display dot by the cursor, and in the case of the vector type window 21, it is possible to designate an arbitrary point of the display figure. You can

Even in the case of the character type window 20, you can move the cursor to any dot position in the same way.
In the character type, only the character digit positions of a fixed rectangular area occupied by each one-character display, which is divided into cells, have meaning for position identification.

Therefore, in that case, each dot position in each one character area does not need to be identified, and it is better to move the cursor with roughness corresponding to the size of the character digit rather than to be able to specify a fine position unnecessarily. Easy to operate.

However, conventionally, since the cursor movement is uniformly controlled as described above, there is a problem that if the cursor is easily positioned in the vector type window, the operation becomes difficult in the character type window.

[Means for solving problems]

 FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of a display device, 1 is a processing device, 2 is an input unit, 3 is a display unit, and 30 of the processing device 1 is an input control unit 6.
The window management unit 31 manages the window according to the designation from the input unit 2 which is received via, and searches the movement ratio table 32 by the attribute of the active window to determine the movement ratio and set it in the movement ratio register 33. The cursor control unit receives the cursor movement amount designation information from the unit 2, determines the movement distance of the cursor display according to the movement ratio set in the movement ratio register 33, and controls the cursor movement.

[Work]

The movement ratio table 32 is a table configured to specify, for each window attribute, a movement ratio used for cursor movement control within the window of the attribute, and is created separately and held in the processing device 1.

Similar to the conventional window management unit 7, the window management unit 30 indexes the moving ratio table 32 according to the attribute of the new active window when switching and displaying the active window of the screen and stores the obtained moving ratio value in the moving ratio register.
Set to 33.

The cursor control unit 31 controls the movement of the cursor display on the screen similarly to the conventional cursor control unit 8. However, as the value of the movement ratio for obtaining the movement amount on the screen from the input movement amount designation, the movement ratio The value held in register 33 is used.

Therefore, it is possible to use an appropriate moving ratio according to the attribute of the active window, thereby improving the operability of moving the cursor.

〔Example〕

In FIG. 1, the parts denoted by the same reference numerals as in FIG.
It has the same function as the conventional display device.
The window management unit 30 and the cursor control unit 31 have the same functions as those of the conventional window management unit 7 and cursor control unit 8 except as described below.

The movement ratio table 32 of FIG. 1 is a table that specifies, for each window attribute such as the character type or vector type described above, the movement ratio used for cursor movement control in the window of that attribute. A table having a structure as shown in FIG. 4 is separately prepared in advance and held in the processing device 1.

In the example of the table in FIG. 4, the movement ratio is specified as "3" for the character type window and the movement ratio "1" is specified for the vector type window.

When the active window is switched, the window management unit 30 indexes the moving ratio table 32 according to the attribute of the new active window when the active window is switched, and sets the obtained moving ratio value in the moving ratio register 33.

The cursor control unit 31 controls the movement of the cursor display on the screen similarly to the conventional cursor control unit 8, but the value of the movement ratio for multiplying the movement amount designation input at that time to obtain the movement amount on the screen. As, the moving ratio value held in the moving ratio register 33 is used.

Therefore, for example, when the movement ratio table illustrated in FIG. 4 is used, "3" is set in the movement ratio register 33 when the active window is a character type, and 3 is set for the movement amount of the mouse. Since it is multiplied by the amount of movement on the screen, the cursor on the screen moves relatively large.

On the other hand, when the active window is a vector type, the movement ratio register 33 “1” is set, so that the movement of the cursor on the screen relative to the movement amount of the mouse 5 becomes relatively small. The operation for moving the cursor to becomes easy. [Effects of the Invention] As is clear from the above description, according to the present invention, the fineness of cursor movement on the screen of a display device that displays a window can be changed according to the window attribute. There is a remarkable industrial effect of improving the sex.
