Abstract

PURPOSE:To designate exactly and easily one optional point on a picture plane by controlling a mouse so that a cursor pointer moves slowly when the mouse is moved slowly, and the cursor pointer also moves quickly when the mouse is moved quickly. CONSTITUTION:In an operation of a microcomputer 9, first of all, an initial value 0.5 is set to a speed magnification register 7. Subsequently, a cursor pointer position is read in a state before a mouse 1 and a cursor start to move. Also, a synchronization type monitor (an interval of 0.05sec) is started. Next, the mouse is moved, and the first time monitor completion, namely, a lapse of 0.05sec is awaited. Subsequently, at the time of this time monitor completion, a position of the cursor pointer is read. Next, from both read values, a cursor moving distance of for 0.05sec, namely a mean speed is derived. Subsequently, a speed table setting in advance is referred to, a value of a new speed magnification is derived, and set to the register 7 again. Next, the time monitor is started, and the subsequent operation is repeated. As a result, the mouse moves quicky to a prescribed point, and thereafter, moves slowly.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a mouse that can control a cursor pointer on a display screen using speed information of mouse movement, and can specify a point on the screen accurately and quickly. Regarding control method.

When an operator moves a control device housing called a mouse on a flat surface, a cursor on a display screen can be moved by a distance corresponding to the distance the mouse is moved. The cursor on the screen has various uses, such as being used in a word processor to specify a position for adding, subtracting, or correcting characters.

[Prior Art and Problems] The cursor position is the location indicated by the cursor pointer, but if you calculate the ratio between the change value of the pointer, that is, the distance the cursor moves, and the actual distance the mouse moves, depending on the device, it may be a fixed value, e.g. The ratio is like 1:3. Therefore, to accurately specify a point on the screen, you only need to move the cursor from a distant place to near that point by a value corresponding to the distance ratio, but this requires a relatively large area and is difficult to specify accurately. In order to do this, it was necessary to perform general operations and then extremely detailed operations. If you want to specify using the error of ICA on the screen, the mouse only allows a position error of 3 dragons. In addition, it often took a long time to get used to operating the mouse.

An object of the present invention is to improve the above-mentioned drawbacks by controlling the cursor pointer to move slowly when the mouse is moved slowly, and the cursor pointer to move quickly when the mouse is moved quickly to move the mouse in a narrow space. An object of the present invention is to provide a mouse control method that enables accurate and easy designation of any one point on a screen.

[Means for Solving the Problems] The means of the present invention for solving the above-mentioned problems is to move the cursor on the display screen by a distance corresponding to the moving distance of the mouse and according to a preset magnification. In a mouse control method comprising a control mechanism, means for making the magnification setting variable; and means for calculating the ratio between the distance the mouse is moved per unit time and the distance the cursor is moved during the same time;
and means for indexing a cursor speed magnification table based on the output of the means for calculating the acid ratio, and the means for varying the magnification setting is operated by the output of the indexing means.

! "Example" Embodiments of the present invention shown in the drawings will be described below.

In the configuration diagram of an embodiment of the present invention shown in FIG. 1, 1 generally represents a mouse, and 2 generally represents a display device.

3.4 is a switch provided in the mouse 1, 3 is for starting the cursor movement process, and 4 is for interrupting the process. 5 is a disk installed perpendicular to the bottom of the mouse to measure the direction of mouse movement and its distance; 6 shows the cursor control mechanism as a whole; inside there is a register for setting the magnification of the movement speed of the mouse and cursor. 7. Magnification table 8. Microcomputer 9
Equipped with such things. The magnification table is a table that shows the relationship between mouse movement speed and speed magnification, as will be described later.

When the switch 3 is operated for the first time, the operation according to the present invention is not performed, and conventional cursor movement is performed.

"2" is set in the speed magnification register 7, and the moving direction and distance of the mouse 1 are determined by the processing of the microcomputer 9 with respect to the rotation of the disk 5 in the mouse 1. The microcomputer 9 calculates the direction and distance in which the cursor moves, and moves the cursor twice as far in the same time as the mouse moves per unit time.

Next, when the switch 3 is pressed and operated again, the operation according to the present invention is executed. A flowchart of the microcomputer 9 is shown in FIG. First, in step ■,
Set the speed multiplier register 7 to an initial value of 0.5. This gives the operator the impression that the cursor moves extremely slowly compared to the conventional method. Next, in step (2), the cursor pointer position is read before the mouse and cursor start moving. Also, in step (3), synchronous time monitoring is started. This time interval is set to about 0.05 seconds. Step (2) starts moving the mouse and waits for time monitoring to be completed, that is, for 0.05 seconds to elapse. During this waiting period, the cursor pointer begins to move by a distance according to the magnification factor of 0.5. When time monitoring is completed in step (2), the position of the cursor pointer is read. In step (2), the moving distance of the cursor for 0.05 seconds, that is, the average speed, is calculated from the information in steps (2) and (2).

Then, the average speed between the O and O5 modes for the mouse 1 is calculated in relation to the current value of the speed multiplier register 7, 0.5.

In step (3), the magnification table is indexed, a new speed magnification value is entered, and the speed register 7 is reset. For example, the magnification table is determined as shown in the table below.

The processing steps now return to ■, start time monitoring, and
Repeat steps up to. As a result, it feels more like moving the mouse quickly, and the cursor moves much faster. FIG. 3 is a diagram showing the movement of the mouse and the movement of the cursor in correspondence. In Figure 3, the mouse is accelerated to 25 cm/s after 0.3 seconds, then slowly moves to 1
The movement is shown by a solid line assuming that it stops after a second. The broken line shows a situation in which when the cursor is moved with the speed multiplier register set to 2, control is performed at time intervals of 0.05 seconds. A line segment shown by connecting a white circle and a black circle with a solid line indicates a situation in which the cursor moves according to the embodiment of the present invention. That is, it can be seen that after 0.3 seconds, the cursor is moving at a speed of 100 cn+/second, and after 0.85 seconds, the cursor is moving more slowly than the mouse. In the case of FIG. 3, the mouse is indicated by a solid line of approximately 14.06 cm, and the cursor is indicated by a broken line of approximately 28.13 cm. According to the present invention, the cursor moves by approximately 36.96 cn+ per second, so the distance traveled by the cursor is increased according to the present invention.

Next, when the switch 4 is pressed, an interrupt is generated to the microcomputer 9, and the process proceeds to the exit routine shown in FIG. After the interrupt step (■), the synchronous time monitoring is canceled in step (2), and the standard value "2" is set in the speed multiplier register 7 in step [phase].

In this state, the cursor in FIG. 3 can perform the movements indicated by the broken lines.

[Effects of the Invention] In this way, according to the present invention, the distance between the mouse and the cursor movement is calculated in units of time and converted into speed, and the cursor movement speed is determined to be lower than the mouse movement speed using a predetermined speed multiplier table. Since it obtains a fast state, when specifying a point on the screen, it moves rapidly until it reaches a point close to the predetermined point, and then moves slowly, allowing for accurate specification. Therefore, the area of the plane on which the mouse is moved can be smaller than in the past.
