Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mouse control device that is a pointing device for specifying a position on a display screen of a display device.

[Summary of the invention] This invention calculates the amount of cursor movement by multiplying the amount of mouse movement calculated as the mouse moves by the conversion ratio calculated according to the continuous movement time of the mouse. The amount of cursor movement relative to the amount of mouse movement is increased at an accelerating rate with the continuous movement time, so that the range of movement of the cursor can be increased even when the mouse is operated on a narrow operation surface.

[Prior Art] In a mouse device that controls the movement of a cursor on a display screen to specify a position by moving a mouse on an operation surface, conventionally, the amount of movement of the mouse and the amount of movement of the cursor are Whether it always corresponds to 1 to n (n is constant) or detects the speed of the mouse,
There was one that changed the ratio of mouse and cursor movement in response to the speed.

[Problem that the invention aims to solve] Therefore, when the cursor is moved far, if the operation surface is narrow, even if the mouse is moved from one end of the operation surface to the other,
If the cursor does not reach the target position, it is necessary to lift the mouse, place it back toward the original end, move it again, and repeat the same operation until the cursor reaches the target position, which worsens usability. There was a problem. Furthermore, even when the operation surface is sufficiently wide, the mouse must be moved a large distance in order to move the cursor far, which is not convenient. Furthermore, in order to solve the above-mentioned problems, if the amount of cursor movement is simply increased uniformly relative to the amount of mouse movement, it will be difficult to move the cursor to the target position accurately, and A system that detects the speed of mouse movement and changes the ratio of mouse and cursor movement accordingly, so that when the mouse is moved quickly, the cursor moves more than usual. Since the mouse is always moving quickly when moving, it becomes difficult to move the cursor close to the target point and then stop, making it inconvenient to use.Moreover, you have to keep in mind the speed of mouse movement when operating the mouse. This poses a problem of increasing the burden on the operator.

The present invention was developed based on the above-mentioned circumstances, and it is an object of the present invention to provide a mouse control device that improves usability by increasing the range of movement of the cursor even when operating the mouse on a narrow operation surface. shall be.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

Configuration FIG. 2 is a circuit diagram of a mouse control device according to an embodiment of the present invention, in which a mouse 1 is electrically connected to a mouse control circuit 3 via a cord 2. This mouse 1 has switch buttons SW1 and SW2 for selecting and deselecting the icon specified by the cursor on the CRT display screen.
is provided. When the mouse 1 is moved on the operation surface, the rotation information of a rotatably provided drive ball (not shown) is converted into electrical signals, and the mouse is controlled as X-direction pulses and Y-direction pulses in two mutually orthogonal directions. It is output to circuit 3.

The mouse control circuit 3 can be roughly divided into two types: the mouse control circuit 3 controls the mouse 1, which contains the movement amount of the mouse 1 and the movement status signal (clock φ1) of the mouse 1, based on the X-direction pulse and Y-direction pulse input from the mouse 1; A movement data generation unit 4 that generates movement data, and a conversion ratio that generates a conversion ratio for converting the amount of movement of the mouse 1 according to the movement status signal of the mouse 1 generated by the movement data generation unit 4. Data generation section 5
The operation of the movement data generation section 4 and conversion ratio data generation section 5 is controlled, and the cursor is controlled based on the movement data and conversion ratio data obtained from the movement data generation section 4 and conversion ratio data generation section 5. It is composed of a CPU (central processing unit) 6 for calculating movement position data. The movement data generating section 4 and the CPU 6, and the conversion ratio data generating section 5 and the CPU 6 are connected by a common data bus 7 and a common control bus 8, respectively.

The movement data generation section 4 has a connector 9 for inputting the X direction pulse, Y direction pulse, and input signals of the switch buttons SW1 and SW2 transferred from the code 2 into the movement data generation section 4, and the X direction pulse, Y direction pulse, and input signals of the switch buttons SW1 and SW2. X direction of mouse 1 based on the direction pulse,
A movement amount calculation circuit 10 for calculating each movement amount in the Y direction and outputting a clock φ1 of a predetermined cycle; The switch buttons SW1 and SW2 are configured with a movement buffer 11 for temporarily holding input signals.

The conversion ratio data generation unit 5 determines whether the mouse 1 has been continuously moving for a predetermined period of time or longer, and if the mouse 1 is continuously moving, sets an up counter 13, which will be described below, and determines whether the mouse 1 is not continuously moving. The retrigger timer 12 is used to reset the up counter 13, and the conversion ratio for the movement amount calculated by the movement amount calculation circuit 10 is calculated based on the output signals from the movement amount calculation circuit 10 and the retrigger timer 12. It is composed of an up counter 13 and a conversion ratio buffer 14 for temporarily holding the conversion ratio calculated by the up counter 13.

Operation Next, the operation of the embodiment shown in FIG. 2 will be explained.

When the mouse 1 is moved on the operation surface, the drive ball of the mouse 1 rotates in accordance with the movement, and an X-direction pulse and a Y-direction pulse are output, which are sent to the movement data generation section 4 via the cord 2 and the connector 9. It is input to the movement amount calculation circuit 10. Then, the movement amount calculation circuit 10 counts the X-direction pulses and Y-direction pulses per predetermined time (this predetermined time is defined by the clock CLK input to the movement amount calculation circuit 10), and converts these values into distance data. are converted into the X-direction movement amount and Y-direction movement amount of the mouse 1 and output to the movement amount buffer 11 and held in the movement amount buffer 11. Further, the movement amount calculation circuit 10 outputs a clock φ1 to the CPU 6, retrigger timer 12, and up counter 13 while the X direction pulse and Y direction pulse are input from the mouse 1. Then, CPU6 uses this clock φ1.
is received as a movement occurrence notification signal, and upon reception of this clock φ1, outputs a clock φ2 to the movement amount buffer 11 via the control bus 8,
The input signal of the switch button SW1 or switch button SW2 held in the movement amount buffer 11, the amount of movement in the X direction, and the amount of movement in the Y direction are taken in.

Next, the operation of the conversion ratio data generating section 5 will be explained with reference to FIG.

As mentioned above, the clock φ1 is output while the X-direction pulse and Y-direction pulse are being input from the mouse 1, and is input not only to the CPU 6 but also to the retrigger timer 12 and up counter 13.
That is, as shown in FIG. 3, at the stage (time T1) when the mouse 1 is not moved at all and no X-direction pulse or Y-direction pulse is input,
The clock φ1 is not output from the movement amount calculation circuit 10. After that, when the mouse 1 is moved and an X-direction pulse and a Y-direction pulse are input to the movement amount calculation circuit 10, a pulse of clock φ1 is output at time T2, and these pulses are sent to the CPU 6 and the retrigger timer 1.
2. Input to up counter 13. and,
If the mouse 1 continues to be moved, the clock φ1 of a predetermined period is continuously output. After that, when you stop mouse 1, as shown at time T7,
The output of clock φ1 is also stopped, and when mouse 1 is moved again, clock φ1 is output as shown after time T8.
will start being output again.

When the retrigger timer 12 is not receiving the clock φ1, its output TO is "1", and this "1" is input to the reset terminal R of the up counter 13, and the up counter 13 is reset. , when the clock φ1 is input to the retrigger timer 12, the timer of the retrigger timer 12 is activated, and while the timer is activated, the retrigger timer 12 outputs "0" and applies it to the reset terminal R of the up counter 13, and resets the up counter 13. unlock. In addition, the retrigger timer 12 is activated every time the clock φ1 is input.
When the timer setting time has elapsed, it outputs "1" and resets the up counter 13. Therefore, if clock φ1 is input due to movement of mouse 1 before the timer setting time shown in FIG. 3 times out, the timer is restarted.
Since "0" is continuously output, the up counter 13 is controlled to the set state while the mouse 1 is continuously moved, and the input clock φ1
can be counted.

The up counter 13 operates while "0" is input from the retrigger timer 12 to the reset terminal R.
Clock φ1 input from the movement amount calculation circuit 10
Count up and set the count value to “1”,
It is output to the conversion ratio buffer 14 as a binary signal of "0".

As shown in FIG. 3, the count value of the up counter 13 becomes "1" at time T3, "2" at time T4, "3" at time T6, and thereafter
When the movement of the up counter 13 is stopped, the output TO of the retrigger timer 1 input becomes "1" at time T7, the reset input of the up counter 13 also becomes "1", and the up counter 13 is reset. The value is “1” again at time T8
Then, after time T10, the retrigger timer 12 continues to output "0" due to continuous movement of the mouse 1, and the up counter 13 is in a countable state, so "2", "3", "4", "5" are output. The count goes up. #1 to #4 in FIG. 3 indicate the state of each bit corresponding to the 1st to 4th digits of the up counter 13 that outputs the count value. For example, the count value at time T3 is "1". ”, so #1 to #4 are “1”, “0”, “0”,
Since the count value at time T13 is "5", #1 to #4 are "1", "0", and "0", respectively.
They are “1” and “0”. The count value of the up counter 13 is a count of the clock φ1 outputted from the movement amount calculation circuit 10 at a predetermined period while the mouse 1 is moving, so it is one aspect of the movement status of the mouse 1. This corresponds to continuous travel time.

The count value output from the up counter 13 is held in the conversion ratio buffer 14. The count value held in the conversion ratio buffer 14 is
Each time the clock φ3 is input from the CPU 6, it is output one after another and taken into the CPU 6. The CPU 6 responds to the amount of movement in the X direction and the amount of movement in the Y direction successively generated from the movement amount buffer 11 by the aforementioned clock φ2.
Conversion ratio buffer 1 by clock φ3, respectively.
4 and then multiply the count values successively from 4, and calculate the cursor movement position based on the multiplication result. Therefore, compared to the conventional case where the cursor movement amount is calculated based on the X-direction movement amount and Y-direction movement amount obtained from the movement amount buffer 11, the cursor movement amount is increased. Then,
The range of cursor movement can be increased even on a narrow operation surface. Further, since the count value to be multiplied gradually increases during continuous movement of the mouse 1, the amount of movement of the cursor relative to the amount of movement of the mouse 1 gradually increases as the continuous movement time of the mouse 1 becomes longer. Looking at it from a different perspective, it can be said that while the mouse 1 is continuously moving, the moving speed of the cursor relative to the moving speed of the mouse 1 gradually increases. The reason for doing this is that if the continuous movement time is long, it is thought that the distance the cursor has to move to the target position is long.
This is because the objective can be achieved more effectively by increasing the movement ratio of the cursor. In this way, if the cursor movement speed becomes too fast and it becomes difficult to control the movement of the cursor to the target position, you can temporarily stop movement of the mouse position and then restart movement of mouse 1. For example, as shown at time T8 in FIG. 3, the up counter 13 starts counting again from "1", so the cursor movement speed also returns to the original speed, and the difficulty in controlling the cursor movement is resolved. . Therefore, even when moving the cursor over a large distance, the cursor can be controlled to move accurately to the target position.

In the above explanation, the count value of the up counter 13 is used as it is as the conversion ratio, but this count value can be processed by the CPU 6 to determine the upper limit of the count value, or, for example, the count value "1", "2" ”, “3”… set the conversion ratio to “0.5”
，
By modifying the values to "1" and "1.5", the rate of change in the cursor movement speed may be smoothed, and the cursor movement speed may be initially slowed down. In addition, by shortening the period of the clock φ1, and further reducing the conversion ratio for the count value output from the up counter 13 in the CPU 6, and smoothing the rate of change in the conversion ratio, the rate of change in the cursor movement speed is reduced. It is also possible to consider a method of smoothing the . In addition, switch button SW1 or switch button
Clock φ2 that sequentially outputs the input signal of SW2, the amount of movement in the X direction and the amount of movement in the Y direction, and the count value (conversion ratio)
The period is the same as that of the clock φ3 which continues to output the clock φ3.

Note that the present invention is not limited to the above-mentioned embodiments; for example, instead of calculating the conversion ratio based on the continuous movement time of the mouse 1, it is also possible to calculate the conversion ratio based on the continuous movement distance of the mouse 1. It is. In this case, the continuous moving distance of the mouse 1 may be calculated based on the X-direction pulse and Y-direction pulse output from the mouse 1, and the conversion ratio may be calculated using the calculated value as a reference.

Further, instead of the mechanical mouse used in this embodiment, it is also possible to apply the present invention to an optical mouse.
