Abstract

PURPOSE:To accurately discriminate a drag operation from a click operation by discriminating whether the position shift of a mouse and the time difference are kept under the prescribed value or not between the first push and the first release of a button. CONSTITUTION:When a button push event is received at first, the start point coordinates P1 and a time point T1 are acquired. Then the coordinates P2 and a time point T2 are acquired when a button push release event is received. A click operation is decided when the distance between P1 and P2 is less than a prescribed threshold value together with the time difference (T1-T2) kept under the prescribed threshold value respectively. Otherwise a drag operation is decided. At the time of drag operation, an end point deciding process is carried out since the P2 is equal to the end point coordinates. While the end point is decided after input of the end point coordinate at the time of click operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] A graphic input processing device in which drag operations and click operations can be performed using a mouse.

It is determined whether the position movement of the mouse and the time difference between the first button press and the first button press release are greater than a predetermined darkness value, and one of the above two operations is selected. This is disclosed.

[Industrial application field]

The present invention relates to a two-figure input processing system, and particularly to a two-figure human input processing system that can correctly determine and select a drag operation and a click operation.

[Conventional technology]

2. Description of the Related Art Conventionally, there have been two types of mouse operations: a graphic input mode using a drag operation and a graphic input mode using a click operation.

FIG. 3 shows a form of figure input by the above-mentioned drag operation. That is, in process (2), a figure display start point is acquired, in process (2), it is displayed that it has been acquired as the figure display start point, in process (2), trasogging processing is performed, in process (2), a figure display end point is acquired, and in process Indicate that it has been acquired as the end point of the figure display in ■,
In process (2), drawing processing is performed.

Further, FIG. 4 shows a graphical human power mode by a click operation. That is, in process (2), the figure display start point is acquired, in process (2), it is displayed that it has been acquired as the figure display start point, in process (2), the event is waited for, and in process [phase], the figure display end point is acquired, and the figure display end point is acquired in process [phase]. In step (3), it is displayed that the figure has been acquired as the end point of the graphic display, and in step [phase], drawing processing is performed.

[Problem that the invention seeks to solve]

Both operations as above can be performed, but in the conventional case)
Either one of the above operations is fixedly selected by the device, or (ii) a special operation is added to select which operation to perform, or (iii) both operations are individually permitted. Even if such considerations are taken into account, it is often not possible to correctly determine which operation it is.

In other words, even when a click operation is performed, the mouse may move undesirably between the time the button is pressed and the button is released.
This is likely to be determined as a drag operation.

[Means for solving problems]

The present invention solves the above-mentioned problems and enables drawing by correctly determining both of the above operations in a series of drawing operations.

FIG. 1 shows a basic configuration diagram of the present invention. In the figure, reference numeral 1 represents a processing device, 2 represents a mouse, and 3 represents a click/drag determination section. Further, 4 indicates a first mode in which a rectangle 6 is drawn by a click operation, and 5 indicates a second mode in which a rectangle 6' is drawn by a drag operation. Note that the dotted line in the figure represents the situation in which the mouse 2 is moved. Arrows 8-1 and 8-2 indicate button operations corresponding to drag operations, arrow 9 indicates a button operation for inputting a figure display start point corresponding to a click operation, and arrow 10 indicates a figure display corresponding to a click operation. This represents the end point input button operation.

In the case of the present invention, the click/trasage determining section 3 makes a determination that (I) the difference between the position when the button is pressed and the position when the button is released is less than or equal to the dark value;

and (11) under the condition that the difference between the time when the button is pressed and the time when the button is released is equal to or less than the darkness value T.

It is determined that it is a click operation.

[Effect]

When drawing by drag operation, follow the above second aspect 5.
As shown in the figure, after the button operation 8-1 corresponding to the button press,
The mouse 2 is moved as shown by the dotted line while the button remains pressed, and a button operation 8-2 corresponding to the release of the button is performed.

When drawing by click operation, the above first aspect 4 is applied.
As shown in the illustration, after button operation 9 by pressing and releasing the button,
The mouse 2 is moved and then a button operation 10 is performed by pressing and releasing the button.

The above-mentioned click/trasage determination section 3 performs the above-mentioned button operation 8-1.
The difference between the combination of and 8-2 and the button operation 9 described above is determined.

〔Example〕

FIG. 2 shows an embodiment of the invention. The code 3 in the figure is the first
Same click/drag determination section as shown in the figure.

represents the functional parts of.

The first functional unit 11 is composed of processes ``■'' to ``■'', in which the coordinate P+ and time T corresponding to the figure display start point are obtained in the process ``■'', and the coordinate P+ in the process ``■'' is obtained.
2 and time T2.

The click/drag determination unit 3 performs determination in the same manner as described with reference to FIG.

Then, when a drag operation is determined, the second function 12
In the process ``■'' corresponding to , the coordinate P2 is determined as the graphic display end point. Further, if it is determined that it is a click operation, it corresponds to the third function 13. In other words, the coordinate P2 is ignored, and the end point of the graphic display in the process ``2'' to [phase]' is obtained after waiting for the event in the process ``2''.

〔Effect of the invention〕

As described above, according to the two aspects of the present invention, it is possible to correctly execute drawing by drag operation and drawing by click operation, and it is also possible to use both drawing methods depending on the situation.
