Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a cursor movement control device that controls the movement of a cursor displayed on a display.

[Technical background of the invention and its problems] Generally, OA (
A cursor is displayed on a display such as a CRT used in an office automation device or a control/monitoring device. This cursor specifies the position where information is to be input, and can be moved using a cursor moving means such as a mouse.

The mouse used as the cursor moving means has a spherical shape that can be moved in 360' directions, and when the mouse is moved by a predetermined amount in a predetermined direction, the cursor on the display will also be moved by the same amount in the same direction. It has become. This is because the direction and amount of movement of the cursor are controlled based on the X-direction pulse and Y-direction pulse that are generated in accordance with the direction and amount of movement of the mouse.

In this way, conventionally, the amount of mouse movement and the amount of cursor movement have been the same. Therefore, if you want to move the cursor to a far position on the display, you have to move the mouse a lot, which poses a problem in operability. Therefore, when the amount of movement of the cursor is large, it takes time to minutely control the position of the cursor.

[Purpose of the invention]

The present invention was made based on these circumstances,
The purpose is to provide a cursor movement control device that can improve the operability of a cursor moving means and that can easily control minute positions of the cursor even when the amount of cursor movement is large. be.

[Summary of the invention]

In order to achieve the above object, the present invention counts pulses generated within a predetermined time by a pulse counting means according to the movement amount, movement speed, and movement direction of a cursor movement means for moving a cursor on a display, A cursor movement command section commands the moving speed and direction of the cursor based on the number of pulses counted within the predetermined time, and a cursor control section controls the movement of the cursor in accordance with this command. It is something.

[Embodiments of the invention]

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, reference numeral 1 denotes a mouse as a cursor moving means, which can move in 360° directions, and an X-direction pulse Px and a Y-direction pulse Py are generated depending on the amount and direction of movement of the mouse 1. It is expected to occur.

The generation cycle of these X-direction pulses Px and Y-direction pulse PY changes depending on the moving speed of the mouse 1. When the mouse 1 is moved at a high speed, the generation cycle becomes short, and when the mouse 1 is moved at a high speed, the generation cycle becomes short. If you move it with , the generation cycle will become longer.

For example, in FIG. 2, when the mouse 1 is slowly moved in the same direction (six directions) in order to move the cursor 11 displayed on the display 10 in eight directions in FIG. The X-direction pulse Px generated from is Ax in FIG. 3, and the Y-direction pulse Py is the third
It is not generated like Ay in the figure. Also, the above cursor 1
1 in eight directions in FIG.
When quickly moved in the same direction (direction B), the X-direction pulse Px generated from the mouse 1 becomes Bx in FIG. 3, and the Y-direction pulse Py becomes BY in FIG. In this way, when the moving speed of the mouse 1 changes, the number of pulses generated within the predetermined time T changes.

2a is a first counter that counts the X-direction pulses Px generated from the mouse 1, and the counter value counted by this 10th counter 2a is stored in the first storage unit 3a at a predetermined timing. It has become a thing.

On the other hand, 2b is a 20th counter that counts the Y-direction pulse PY generated from the mouse 1, and the counter value counted by this second counter 2b is stored in the second storage section 3b. It has become.

4a is a counter value of the X-direction pulse Px stored in the first storage section 3a and a predetermined time (for example, T in FIG. 3).
This is a first calculation unit that calculates the amount of change ΔX of the X-direction pulse Px by comparing the counter value of the first counter 2a after the elapsed time, and this amount of change ΔX is given to the cursor movement command unit 5. It becomes. On the other hand, 4b indicates the counter value of the Y-direction pulse PY stored in the second storage section 3b and the counter value of the second counter 2b after the predetermined time has elapsed.
The amount of change Δ of the Y-direction pulse PY is determined by comparing with the counter value of
This is a second calculation unit that calculates Y, and this change mΔY is also given to the cursor movement command unit 5.

In the cursor movement command unit 5, the amount of change ΔX
, ΔY are compared with predetermined reference values to determine the magnitudes of the amounts of change ΔX and ΔY, and the moving speed and direction of the cursor 11 are determined based on the magnitudes of the amounts of change ΔX and ΔY, and the cursor control unit 6 A command signal S is output to the controller.

Further, the cursor control unit 6 inputting the command signal S,
In response to this command signal S, a cursor 11 displayed on the display 10 is moved.

Next, the operation of this apparatus will be explained with reference to the flowchart shown in FIG. 4 from time to time. As an initial state, display 1
0 according to the current position of the cursor 11 displayed above. The counter values of the second counters 2a and 2b are read (step (hereinafter abbreviated as ST) 1), and the counter values of the second counters 2a and 2b are read, respectively. stored in the second storage units 3a, 3b (ST2
). In this state, when the mouse 1 is moved to move the cursor 11 to a desired position, the x direction pulse P
The x and y direction pulses PY are generated at a predetermined period, and the first . Second counter 2a.

2b counts the number of generated pulses. Then, after the predetermined time T has elapsed from the start of counting, the first . In the second arithmetic units 4a, 4b, the first . The counter values of the second counters 2a, 2b are read (ST3), and this counter value and the first . The counter values stored in the second storage units 3a and 3b are compared, and the amounts of change ΔX and ΔY are calculated, respectively (ST4).

Next, in the cursor movement command unit 5, the amount of change Δ
X and ΔY are compared with a first reference value M and a second reference value N (>M), respectively (ST5°6). Then, for example, if the amount of change ΔX is smaller than the first reference value M, a command signal S1 for moving the cursor 11 in the X direction at a low speed is sent to the cursor control unit 6 (ST7).
. Then, the amount of movement of the cursor 11 controlled by the cursor control section 6 becomes smaller. In addition, the above change amount Δ
If X is thicker than the first reference value M (less than the second reference value N), a command signal S2 for moving the cursor 11 in the X direction at a medium speed is sent to the cursor control unit 6. (ST8). In this case, the amount of movement of the cursor 11 is medium. Furthermore, if the amount of change ΔX is larger than the second reference value N, the cursor 11 is moved at high speed in the X direction. A command signal S3 for movement is sent to the cursor control unit 6 (ST9). In this case, the amount of movement of the cursor 11 increases. The same applies to the amount of change ΔY.
The amount of change ΔY and the first. Second reference value M.

From the relationship with N, move the cursor 11 in the Y direction.

A command signal 84.85°86 for moving at a medium to high speed is sent to the cursor control unit 6, and the command signals 81 to S
The amount of movement of the cursor 11 is controlled according to 6.

Here, the magnitude of the amount of change ΔX or ΔY is determined by the mouse 1
Depends on the speed of movement. That is, when the mouse 1 is moved quickly, the period of the generated pulse becomes shorter, and the first . Since many pulses are counted by the second counters 2a and 2b, the first. Second calculation unit 4a
, 4b, the amounts of change ΔX and ΔY become larger.

Conversely, if the mouse 1 is moved slowly, the cycle of the generated pulses becomes longer and the number of pulses counted within the predetermined time T becomes smaller, so the amount of change ΔX.

ΔY becomes smaller.

Therefore, even if the amount of movement of the mouse 1 is the same, if the mouse 1 is moved quickly, the cursor 11 will move a lot, and if it is moved slowly, the cursor 11 will move a little.

Thus, according to this embodiment, even if the amount of movement of the mouse 1 is small, the cursor 11 can be moved far by moving the mouse 1 quickly. Therefore, the operability of the mouse 1 is improved, and minute position control of the cursor 11 can be easily performed even when the cursor 11 is moved by a large amount.

Note that the present invention is not limited to the above embodiments.

For example, in the embodiment described above, the amount of movement of the cursor 11 with respect to one pulse generated from the mouse 1 does not change, but the amount of movement of the cursor 11 may be varied by a switch or the like. By doing so, further improvement in operability can be expected. Further, in the above embodiment, a case was shown in which a mouse was used as a means for moving the cursor, but
It can also be applied to other cursor movement means such as a joystick. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As detailed above, according to the present invention, the pulses generated according to the moving layer, moving speed, and moving direction of the cursor moving means for moving the cursor on the display are counted within a predetermined time by the pulse counting means,
A cursor movement command section commands the moving speed and direction of the cursor based on the number of pulses counted within the predetermined time, and a cursor control section controls the movement of the cursor in accordance with this command. Therefore, it is possible to provide a cursor movement control device that can improve the operability of the cursor moving means and can easily perform minute position control of the cursor even when the amount of movement of the cursor is large.
