DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mouse cursor movement control system on an information processing apparatus screen, and more particularly to a mouse cursor movement control system by operating a pointing device such as a mouse or a slide pad.

[0002]

2. Description of the Related Art As a mouse cursor movement control method in the prior art, for example, as in a method disclosed in Japanese Patent Application Laid-Open No. 8-69596, a region near the mouse cursor position is searched based on the current position of the mouse cursor. There is an area which checks whether an object to be operated exists within a search area range, and automatically moves a mouse cursor to the position of the object when the object exists.

In the method disclosed in Japanese Patent Laid-Open Publication No. Hei 6-83540, it is checked whether or not an object to be operated exists on a straight line indicating the moving direction of a mouse cursor on a screen. The mouse cursor is automatically moved to the position of the object.

[0004]

The first problem is that, in the prior art, in the method in which the search area is near the current mouse cursor position, the operation target object which the operator wants to move the mouse cursor and the current object When the distance from the mouse cursor position is large, the operability is not good.

The reason is that a large number of operations of the pointing device are required. For example, if the mouse is used, the distance that must be moved increases, and if the mouse is a slide pad, the operation of moving the finger must be repeated many times.

A second problem is that, in the prior art, in the method of searching for an operation target object on an extension of the current moving direction of the mouse cursor, the operation target object which the operator wants to move the mouse cursor and the current operation target object are displayed. When the distance from the mouse cursor position is small, operability is not good.

The reason is that, although the operation target object for which the mouse cursor is to be moved is near the current mouse cursor position, depending on the direction in which the mouse cursor is moved, the mouse cursor is moved to an object which is not intended at all. Is likely to move.

An object of the present invention is to provide an operation for moving a mouse cursor on a screen of an information processing apparatus, particularly on a screen on which an object to be operated is set finely, by operating the pointing device easily and accurately. Moving the mouse cursor to the target object.

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. Referring to FIG.
The mouse cursor movement control system of the present invention includes an information processing device 11, a display 12, and a pointing device 13 such as a mouse, a trackball, or a slide pad.

The information processing apparatus 11 includes a pointing device input control unit 14, a mouse cursor position calculation unit 15, and a screen display control unit 16.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIG. FIG. 2 is a flowchart showing the operation of the embodiment of the present invention. Each time the pointing device 13 is physically operated, the pointing device input control unit 14 updates the mouse cursor position information according to the operation information. The mouse cursor position calculation unit 15 detects the mouse cursor position information of the pointing device input control unit 14 at regular intervals, and calculates the current position, movement direction, and movement speed of the mouse cursor based on this information. The screen display control unit 16 displays the mouse cursor at the mouse cursor position on the screen determined by the mouse cursor position calculation unit 15.

Next, the process of determining the mouse cursor position to be displayed on the screen in the mouse cursor position calculation unit 15 will be described in detail with reference to FIG. First, determination processing S
In step 1, it is determined whether the current moving speed of the mouse cursor is "0", in other words, whether the mouse cursor is stopped. Specifically, it is determined whether the currently sensed mouse cursor position is the same as the previous position. If the moving speed of the mouse cursor is not “0”, the process is terminated without changing the position so that the mouse cursor is displayed at the same position.

If the moving speed of the mouse cursor is "0", the process of resetting the mouse cursor position is performed. The processing method is different depending on the value of the moving speed immediately before in the determination process S2. If the immediately preceding moving speed is less than the reference value in the determination process S2, the vicinity of the current mouse cursor position is set as the search range of the object to be moved in the process S4. On the other hand, if the immediately preceding moving speed is equal to or higher than the reference value, a search range of a distance range corresponding to the speed in the moving direction is set in step S3. In step S5, the mouse cursor position is set to the operation target object closest to the current mouse cursor within the set search range.

Next, embodiments of the present invention will be described in detail with reference to the drawings. The basic configuration and processing flow are as shown in FIGS. FIG. 3 is an explanatory diagram showing an example of determining the immediately preceding moving speed in the processing S2 of FIG. FIG.
FIG. 3 is an explanatory diagram showing an example of setting a search range in processing S3 of FIG. 2. FIG. 5 is an explanatory diagram showing an example of setting a search range in the processing S5 of FIG.

Referring to FIG. 3, in the present embodiment, the sampling period 31 of the mouse cursor position is 50 [ms], and the time 32 for determining the speed immediately before the mouse cursor stops is 2.
00 [ms], the reference value 33 in the determination processing S2 of FIG.
Is set to 600 [mm / s]. FIG. 3 shows a movement speed 0 point 34 at which the movement speed of the mouse becomes “0” and a maximum movement speed 35 immediately before the stop. FIG.
Shows the search range of the mouse cursor destination when the moving speed immediately before the mouse cursor stops is equal to or higher than the reference value 33. FIG. 5 shows the search range when the moving speed is lower than the reference value 33.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 3 shows a transition of the speed when the operator of the information processing terminal attempts to move the mouse cursor on the screen by operating the pointing device 13. At the moving speed 0 time point 34, the moving speed of the mouse cursor is “0”, that is, the mouse cursor has stopped. Here for the first time Figure 2
The determination in the determination process S1 is YES, and the process proceeds to the mouse cursor resetting process after the determination process S2.

First, in the judgment processing S2, the maximum speed of about 700 [mm] for 200 ms before the mouse cursor stops.
/ S]. Since this value is equal to or greater than the value 600 [mm / s] set in the reference value 33, the determination in the process S2 is YES.

Next, in step S3, as shown in FIG. 4, a search range 44 of the mouse cursor movement destination is set in the mouse cursor movement direction 42 of the mouse cursor movement trajectory 43 immediately before the stop. At this time, the search range 44 is set to a wide range in proportion to the speed of the mouse cursor immediately before. Finally, in the processing S5, the operation target object located closest to the current mouse cursor position in this search range is searched, and the mouse cursor position is updated to that position. In the example of FIG. 4, the mouse cursor automatically moves to the position of the “OK” object 45 closest to the current mouse cursor position 41 among the objects 45.

If the moving speed immediately before stopping the mouse cursor is less than the reference value 33 in the judgment of the process S2 in FIG. 2, the process S4 is executed, and the current mouse cursor position is set as shown in FIG. A search range 52 of a movement destination is set near 51. Then, similarly, in the processing S5, the operation target object located closest to the current mouse cursor position 51 in the search range is searched, and the mouse cursor position is updated to that position. In the example of FIG. 5, the mouse cursor automatically moves to the "cancel" object position closest to the current mouse cursor position 51 among the objects 53.

[0024]

As described above, the first effect of the present invention is that the mouse cursor can be accurately moved to an operation target object at a distant distance with a small operation of the pointing device.

The reason is that the width of the search range to which the mouse cursor is moved is determined according to the magnitude of the speed immediately before the mouse cursor is stopped. This is because the mouse cursor can be moved to an object located at a distance from the user.

The second effect is that it is possible to reduce the possibility that the mouse cursor is erroneously moved to a position not intended by the operator.

The reason is that when the moving speed of the mouse cursor is lower than a certain reference value, the function of moving the mouse cursor to a remote position described in the first effect does not work. That is, by slowly operating the pointing device by the operator, it is possible to prevent the mouse cursor from being moved to an unintended position by mistake.
