Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mouse cursor control device, and more particularly to a mouse input device used as an input device of a computer. (G06F
3/033)

[0002]

2. Description of the Related Art In a conventional mouse cursor control device, the shape of a mouse cursor is fixed and always represented by an arrow pointing in the same direction. FIG. 5 shows an example of a conventional mouse cursor shape, where 501 is a position pointed by a mouse, and 502 is a mouse cursor. Conventionally, during normal operation, the shape of the mouse cursor 502 is fixed, and the size of the mouse cursor is fixed to a range shown by a rectangle 503 having 32 pixels vertically and 16 pixels horizontally.

[0003] Also, changing the shape of the mouse cursor has been filed in Japanese Patent Application Laid-Open No. Hei 10-91385, which prevents the mouse from hindering the display of a moving image. When a mouse is not needed, the shape of the mouse cursor is changed so that it does not get in the way.

Further, in the prior art, the ratio of the amount of movement of the mouse cursor to the movement of the mouse when a human moves the mouse (Mickey ratio) is constant during normal use. The ratio change program is executed once to reset the ratio to an easy-to-use ratio, and thereafter, the moving ratio is fixed at the set Mickey ratio.

A conventional mouse cursor control method will be described below with reference to FIG. In FIG. 4, reference numeral 101 denotes a mouse, which the operator moves up, down, left, and right. Mouse 101
Is a device for detecting the amount of vertical and horizontal movement, so in order to associate this with the position on the monitor screen,
It is necessary that the moving amount is integrated by the integration unit 102 and this value is output as the mouse coordinate position on the monitor screen. The integrator 102 simultaneously checks for overflow. That is, when the number of pixels of the monitor screen is 640 pixels in the horizontal direction and 480 pixels in the vertical direction, it is necessary to restrict the abscissa to the range of 0 to 639 and the ordinate to the range of 0 to 479. When the abscissa position of the mouse is 639, the abscissa value is continuously output as 639 even if the amount of lateral movement from the mouse 101 further increases. Thus, the coordinate position on the screen indicated by the mouse does not deviate from the monitor screen. When the coordinate position of the mouse output from the integration unit 102 changes, the display control unit 403 needs to rewrite the position of the mouse cursor on the monitor screen.

For this purpose, first, the currently displayed mouse cursor is deleted. Since the background image was originally drawn in the portion where the mouse cursor is currently displayed, the mouse cursor can be erased by overwriting the original background image from above the mouse cursor.
That is, the background image of 512 pixels in the area 503 of 16 pixels horizontally and 32 pixels vertically shown in FIG. 5 is stored in the image storage buffer 404, and the position of this area on the monitor screen is That is, assuming that the coordinates of 501 are stored in the display position storage unit 405, the image storage buffer 4 is stored based on the position coordinates of the display position storage unit 405.
By writing the image No. 04 into the image memory 406,
The mouse cursor can be deleted from the monitor screen.

Next, the mouse cursor is written at a new position. Before that, it is necessary to save an image of a portion where the mouse cursor is written for the next movement. For this reason, the mouse coordinate position from the integration unit 102 is written into the display position storage unit 405, and image data for 16 pixels in width and 32 pixels in height using the coordinates as the upper left corner is stored in the image storage buffer 404 from the image memory 406.
Copy to Thereafter, by writing the determined mouse cursor into the image memory 406, the mouse cursor can be moved.

[0008]

However, in the above-mentioned prior art, since the mouse cursor is always represented by an arrow pointing in the upper left direction, the mouse cursor protrudes from the monitor screen depending on the position of the mouse. There is.

This situation will be described with reference to FIG. In FIG. 3, reference numeral 301 denotes a monitor screen, and a window 302
Etc. are displayed. Normally, the mouse cursor is 303
When the mouse is moved to the lower right of the screen when pointing to the icon 305 displayed at the lower right of the screen, the mouse cursor moves to the monitor screen as indicated by a broken line 304. Since the mouse protrudes from 301, there is a risk that the position of the mouse may be lost. That is, in the above example, when the coordinate position of the mouse points to the horizontal 639 and the vertical 479, for example, only one pixel at the lower right corner of the mouse is displayed in the lower right corner of the monitor screen, so that only the state is checked. However, there was a problem that the position of the mouse could not be known.

The fixed Mickey ratio is not a problem when a flat object is shown on the monitor screen. However, when a three-dimensional object is shown, an object is brought forward. In either case or when there is an object in the distance, if the mouse moves at a constant speed, it will make the human feel unnatural. Furthermore, since the far part of the three-dimensional shape is drawn smaller than the one in front, there is also a problem that when pointing this with the mouse, the positioning accuracy of the far part deteriorates.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to prevent a mouse cursor from protruding out of a monitor screen and to lose sight of the mouse cursor, and to perform a suitable operation suitable for human senses. It is an object of the present invention to provide a mouse cursor control device capable of realizing a mouse having a sense.

[0012]

In order to solve the above-mentioned problems, a mouse cursor control device according to the present invention changes the arrow direction of a mouse cursor according to a physical position on a monitor screen. .

As described above, the direction of the arrow of the mouse cursor is directed from the center of the monitor to the outer periphery, so that the mouse cursor main body is always located at the center of the monitor even near the outer periphery of the monitor image. Thus, the mouse cursor does not protrude outside the monitor screen.

Further, in the mouse cursor control device according to the present invention, in an area displaying a three-dimensional image, the size of the mouse cursor is changed according to the depth of the object, and the Mickey ratio is changed on the same scale. It is something that can be changed.

[0015]

(Embodiment 1) Hereinafter, Embodiment 1 corresponding to Claims 1, 2, and 3 of the present invention.
Will be described with reference to the drawings. FIG. 2 shows a mouse cursor 203 displayed at each position on the monitor screen 201.
To 207 are shown at the same time. Actually, only one mouse cursor is displayed at the same time. However, FIG. 2 shows a plurality of mouse cursors for explanation. Here, the direction of each mouse cursor is the current mouse position,
In the direction of a straight line connecting to the center 202 of the monitor screen, and
The monitor screen is facing outward.

By doing so, when the mouse comes to the upper left of the monitor screen 201, the result is as shown at 203, which is almost the same as the conventional mouse. When it comes, it becomes like 207, and the mouse cursor does not protrude from the monitor screen unlike the related art. Similarly, 204, 206, etc.
Even at a position where the mouse cursor protrudes from the monitor screen, the mouse cursor remains in the monitor screen.

The means for realizing the display of the mouse cursor shown in FIG. 2 will be described with reference to FIG. FIG.
1 shows a configuration of a mouse cursor control device according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 101 denotes a mouse, which the operator moves up, down, left, and right. Since the mouse 101 is a device for detecting the amount of vertical and horizontal movement, in order to associate this with the position on the monitor screen, the integration unit 102 integrates the amount of movement and this value is displayed on the monitor screen. Must be output as mouse coordinates.
The integrator 102 also checks for overflow at the same time. That is, if the number of pixels on the monitor screen is
For 40 pixels and 480 pixels vertically, the abscissa is 0 to 63
9. Since the ordinate needs to be limited to the range of 0 to 479, for example, when the coordinate position of the mouse output from the integration unit 102 is 639, even if the horizontal movement amount from the mouse 101 further increases, 639 is continuously output as the value of the abscissa. Thus, the coordinate position on the screen indicated by the mouse does not deviate from the monitor screen.

After the coordinate position of the mouse is determined, a process in the shape determining unit 103, which is a feature of the present invention, is performed. The shape determination unit 103 is for determining the direction of the mouse cursor, and assuming that the coordinate position of the mouse is (X, Y), after determining the value of (X-320, Y-240), this vector Find the angle of Here, (320, 24
0) is the coordinates of the center 202 of the monitor screen. The angle of the vector obtained here can take a value of 0 to 360 degrees,
Since it is difficult to prepare mouse cursor shapes for all directions, here, 36 types of mouse cursor shapes are prepared every 10 degrees. That is,
The shape determining unit 103 has a function of selecting one of 36 types of mouse cursors from the current mouse coordinate position.

Next, the operation of displaying or erasing the mouse cursor whose shape has been determined here may be repeated, but here, one problem which has not existed in the prior art is as follows. Occurs.

That is, since the shape of the conventional mouse cursor is constant, as shown in FIG.
02 mouse coordinate position 501 and cursor display area 50
The position of the upper left corner of No. 3, ie, the display start position, coincided. On the other hand, in the first embodiment, as shown in FIG. 6, since the shape of the mouse cursor changes (the direction of the mouse cursor changes), the mouse coordinates (tip of the mouse) 6)
Despite being 02, the mouse cursor display start position is 604, and both have different coordinates. When the mouse cursor becomes 605, the mouse coordinates become 606.
In addition, the mouse cursor display start position is considerably different from 608. In addition, in the case of the mouse cursors 601 and 605, the areas 603 and 607 in which the background portion needs to be saved have different vertical and horizontal pixel numbers, respectively. Become.

Therefore, in the first embodiment, the mouse coordinate position 602 and the mouse cursor display start position 604
, And the number of vertical and horizontal pixels in the storage area 603 are always managed. That is, these values are:
When the mouse cursor shape is determined, it is uniquely determined. Therefore, each value is prepared in advance for 36 types of cursor shapes. Therefore, when the shape determining unit 103 selects the mouse cursor shape from among 36 types, the relative positional relationship between the mouse coordinate position and the mouse cursor display start position corresponding to the mouse cursor shape and the number of vertical and horizontal pixels in the storage area are changed. decide. The display position determination unit 104 obtains the absolute position of the mouse cursor display start position from the mouse coordinate position output from the integration unit 102 and the relative positional relationship between the mouse coordinate position and the mouse cursor display start position.

Using the above information, the display control unit 105 rewrites the position of the mouse cursor on the monitor screen when the coordinate position of the mouse output from the integration unit 102 changes. For this purpose, the currently displayed mouse cursor is first erased. Since the background image was originally drawn in the portion where the mouse cursor is currently displayed, the original background image may be overwritten from above the mouse cursor in order to delete the mouse cursor. That is, the original background image is stored in the image storage buffer 107, and the coordinate position of the image on the monitor image and the number of vertical and horizontal pixels of the storage area are stored in the display position storage unit 108.
, The mouse cursor can be deleted from the monitor screen by writing the background image into the image memory 109 based on the coordinate position and the number of pixels.

Next, the mouse cursor is written at a new position. Before that, it is necessary to save an image of a portion where the mouse cursor is written for the next movement. For this reason, the absolute position of the mouse cursor display start position obtained by the display position determining unit 104 and the number of vertical and horizontal pixels of the storage area are written into the display position storage unit 108, and the coordinates are set to a predetermined size with the upper left corner. Is copied from the image memory 109 to the image storage buffer 107. Thereafter, by writing the determined mouse cursor into the image memory 109, the mouse cursor can be moved.

The mouse cursor control device according to the first embodiment has a function of displaying the mouse cursor in an area within an angle range of 90 degrees with the point indicated as the upper left point, and a function of the mouse. A function to display the mouse cursor rotated around the point indicated by the movement, and to determine the rotation angle so that the mouse cursor does not protrude from the monitor screen near the periphery of the monitor screen and display the mouse cursor And a function that can prevent the user from losing the position of the mouse cursor.

The above is a description of one embodiment of the present invention. In the first embodiment, when the mouse is moved from the position 208 to the position 209 in FIG. The direction of the mouse cursor is suddenly switched near. This is the same when moving up and down, but when the mouse passes near the center 202 of the monitor screen, a sudden change in the cursor direction occurs. Although this poses no problem in practical use, but gives an uncomfortable feeling in operation, a second embodiment of the present invention capable of preventing this sudden change in direction will be described with reference to FIG. Will be explained.

(Embodiment 2) FIG. 7 is a diagram showing details of a shape determining unit 103 in a mouse cursor control device according to Embodiment 2 of the present invention. The other parts have the same configuration as in the first embodiment, and a description of the other parts will be omitted.

In the shape determining unit 103 in the mouse cursor control device according to the second embodiment shown in FIG. 7, the mouse coordinate position output from the integrating unit 102 is input to the ideal direction determining unit 701, and the current mouse coordinate position is set. Determine the ideal orientation of the mouse cursor at the location. This ideal direction is the direction shown in FIG. 2, and outputs the ideal angle as an angle of 0 to 360 degrees according to the processing shown as the processing of the shape determining unit 103 in the first embodiment. If the mouse cursor direction is used as it is, the direction may suddenly change as described above. It was decided to provide.

That is, the direction storage unit 702 stores the direction of the mouse cursor determined at the time of the previous sample, and the adder 703 calculates the difference between them. Naturally, when taking the difference, it is necessary to consider that 0 ° and 360 ° are continuous as values since these values represent angles. For example, the ideal direction determining unit 70
When the output of 1 is 359 degrees and the output from the direction storage unit 702 is 2 degrees, the difference value processed by the adder 703 is 3 degrees instead of 357 degrees.

The comparator 707 compares whether or not the amount of change exceeds the limit value. If the change amount is less than the limit value, the comparator 707 outputs the value as it is. This output result is added by the adder 708 to the direction at the time of the previous sample from the direction storage unit 702 and output as the current cursor direction, and is stored in the direction storage unit 702 for the next processing. You. Note that the limit value of the amount of change in the direction shown here may be an appropriate constant value, but in practice, this limit value is naturally proportional to the speed of the mouse.

For this purpose, first, the current coordinates of the mouse output from the integrator 102 in order to determine the speed of the mouse,
The current speed of the mouse can be obtained by taking the difference from the mouse coordinates at the time of the previous sampling stored in the mouse position storage unit 704 by the adder 705. The maximum change amount determination unit 706 uses this value to determine the limit amount and transmits the value to the comparator 707. Note that the maximum change amount determination unit 706 may associate the limit value with the mouse speed in a proportional relationship or may use another monotonically increasing function. As described above, the direction of the mouse cursor can be changed naturally without causing discontinuity in the direction of the mouse cursor.

The mouse cursor control device according to the second embodiment has a function of storing the angle of the mouse cursor before one sample, and when determining the display angle of the current mouse cursor, one mouse is used. Since the angle change is limited so that it changes continuously from the angle of the mouse cursor before the hour, it is possible to obtain a function that prevents the direction of the mouse arrow from changing suddenly. it can.

(Embodiment 3) Next, Embodiment 3 of the present invention will be described. Conventionally, when a plurality of windows are displayed on a monitor screen, they are superimposed and displayed in a plane as shown in FIG. 3, but recently, in order to make switching between the plurality of windows more efficient, as shown in FIG. It has been studied to display the image three-dimensionally.

FIG. 8 shows a mouse cursor control device according to a third embodiment of the present invention. In the third embodiment, three windows 802 to 804 are three-dimensionally displayed on a monitor screen 801. Even when such a display is performed, the mouse can be operated by moving the monitor screen two-dimensionally as in the related art, but in the third embodiment, the mouse can be used with a more natural feeling. Things.

That is, 802 to 802 on the monitor screen 801
In an area other than the window 804, the mouse cursor 8
05 shows the same display as the conventional one. However, for example, when the mouse cursor enters the area of the window 802, when the mouse cursor moves in an image moving in the depth direction of the monitor screen along the surface of the window 802, the operator feels natural. . For this purpose, it is necessary to perform one of two processes which are not conventionally performed in controlling the cursor of the mouse.

One is to change the size of the mouse cursor. That is, when the mouse cursor 807 is located at a position moved in the depth direction of the monitor screen, the cursor must be smaller than when the mouse cursor 806 is located closer to the front of the monitor screen. Therefore, a process of changing the size of the mouse cursor according to the scale of the position indicated by the mouse is performed.

Thus, in the third embodiment,
When displaying multiple windows on the monitor screen, multiple windows are displayed three-dimensionally in order to make switching between the windows more efficient, and at this time, the mouse cursor enters the window area. In this case, by changing the size of the mouse cursor according to the scale of the position indicated by the mouse, the mouse cursor operates in the image moving in the depth direction of the monitor screen along the surface of the window. Thus, it is possible to obtain something that is naturally felt by the operator.

(Embodiment 4) As described above, when the mouse cursor enters the window area, the mouse cursor operates in the image moving in the depth direction of the monitor screen along the surface of the window. So that
Another method is to change the physical movement amount of the mouse and the movement amount on the screen, and the fourth embodiment employs this method.

That is, as shown in FIG. 8, when the mouse cursor is at 806 and 807, when the mouse is moved by the same amount, the amount of movement on the monitor screen is smaller than that of 807. Is naturally smaller.
Therefore, processing is performed to change the Mickey ratio, which is the moving ratio of the mouse cursor, according to the scale of the position indicated by the mouse. Hereinafter, processing examples for these will be described with reference to FIG.

FIG. 9 is a diagram showing a processing example in the mouse control device according to the fourth embodiment of the present invention. In FIG. 9, reference numeral 101 denotes a mouse, which the operator moves up, down, left, and right. Since the mouse 101 is a device for detecting the amount of vertical and horizontal movement, in order to associate this with the position on the monitor screen, the integration unit 902 integrates the amount of movement, and this value is used by the mouse on the monitor screen. Must be output as the coordinate position. Here, the integration unit 902 multiplies the amount of movement from the mouse by a scale ratio according to the position, and then integrates the amount. This will be described later. When the position of the mouse on the monitor screen 801 is determined, the position classification unit 9
03, the point currently pointed by the mouse is window 8
Classification is made as to which one of 02 to 804 is included or which is not included in any of them. Scale determination unit 904
Then, referring to the scale table 901 according to classification,
Determine the current scale value. The scale values determined here are three types: a cursor display scale value, a vertical Mickey ratio, and a horizontal Mickey ratio. The cursor display scale value means the size of the cursor itself when displaying the mouse cursor, and the vertical Mickey ratio is the amount of movement on the monitor screen relative to when the mouse is actually moved in the vertical direction. Similarly, the horizontal Mickey ratio means the ratio of the amount of movement on the monitor screen to that when the mouse is actually moved in the horizontal direction. The vertical Mickey ratio and the horizontal Mickey ratio obtained here are sent to the integration unit 902 and used to change the cursor movement ratio when the mouse is moved. The cursor display scale value is sent to the shape determining unit 905. The shape determining unit 905 determines the size of the mouse cursor, and determines the shape of the mouse cursor according to the cursor display scale value. Here, the determined mouse cursor may be displayed on the monitor screen. However, since the size of the mouse cursor changes as in the third embodiment, the number of vertical and horizontal pixels in the storage area for the mouse background image is always changed. It shall be managed. Since this value is uniquely determined when the size of the mouse cursor is determined, each value corresponding to the cursor display scale value is prepared in a table in advance. Therefore, at the same time when the shape of the mouse cursor is determined by the shape determining unit 905, the number of vertical and horizontal pixels of the storage area corresponding to the shape is determined.

By using the above information, the display control unit 906 rewrites the position of the mouse cursor on the monitor screen when the coordinate position of the mouse output from the integration unit 902 changes. For this purpose, the currently displayed mouse cursor is first erased. Since the background image was originally drawn in the portion where the mouse cursor is currently displayed, the mouse cursor can be deleted by overwriting the original background image from above the mouse cursor. That is, the original background image is stored in the image storage buffer 90.
7, the coordinate position of the image on the monitor image and the number of vertical and horizontal pixels of the storage area are stored in the display position storage unit 908.
The mouse cursor can be erased from the monitor screen by writing the background image into the image memory 909 based on the coordinate position and the number of pixels. Next, the mouse cursor is written at a new position. Before that, it is necessary to save an image of a portion where the mouse cursor is written for the next movement. For this reason, the position of the mouse cursor and the number of vertical and horizontal pixels of the storage area are written into the display position storage unit 908, and image data of a predetermined size with these coordinates in the upper left corner is transferred from the image memory 909 to the image storage buffer 907. make a copy. Then, move the mouse cursor to
By writing to the image memory 909, the mouse cursor can be moved.

Next, the classification scale table 901 will be described. As described above, the classification scale table 901 is a table in which the cursor display scale value, the vertical Mickey ratio, and the horizontal Mickey ratio are tabulated for each classification. For example, if the mouse position is in the window 802 to 804
Are not included in any of the above, all three scale values are 1. Further, for simplicity, for example, in the case of being included in the window 802, the vertical Mickey ratio is fixed at 1 and the horizontal Mickey ratio is fixed at 0.5, and only the cursor display scale value is set at the front end. The value changes linearly from a value of 1 at a certain point to 0.5 at the end of the deepest part. Similarly, when the window 803 is included, the vertical Mickey ratio is 1, and the horizontal Mickey ratio is 1. Is fixed at 0.3, and only the cursor display scale value is from the value 1 at the front end to 0. 0 at the deepest end.
5 and linearly, and when it is included in the window 804, the vertical Mickey ratio is fixed at 1, the horizontal Mickey ratio is fixed at 0.1, and only the cursor display scale value is changed. , The value at the front end 1
From 0.5 to 0.5 at the end of the deepest part. But with this method,
Since the movement is slightly different from the actual movement, it is necessary to create the classification scale table 901 more accurately for a more natural operation feeling.

Hereinafter, the procedure will be described with reference to FIG. FIG. 10 is a view of the monitor screen shown in FIG. 8 viewed from directly above. 1001 is a human viewpoint, and 1
003 is a view of the monitor screen 801 from directly above,
Reference numeral 1002 denotes a virtual position of the window 802;
004 is a window 80 projected and displayed on the monitor screen.
2. In the figure, the vector obtained by moving the mouse from the front of the virtual window 1002 to the center of the window 1002 is 1005.
On 03, it is observed as a vector 1007. Similarly, from the center of the virtual window 1002, the window 1
The vector moved to the end of the innermost part of 002 is 1006, which is the vector 1010 on the monitor screen 1003.
08 is observed. Actually moved vector 100
5 and 1006 are the same size, but the vectors 1007 and 1008 that display them are obviously different sizes, and it is necessary to consider this change in order to realize the natural movement of the mouse. It can be seen that it is. Therefore, it is assumed that the window displayed on the monitor screen uses a coordinate system as shown in FIG.

Here, the window 1101 has an origin of 11
02, and the x coordinate is taken in the horizontal direction and the y coordinate is taken in the downward direction. At this time, the height of the front end of the window 1101 is hw1, the height of the innermost end is hw2, and the width is w.
w and the original height of the virtual window 1101 is h
