Abstract

PURPOSE:To easily indicate a desired position on a screen by performing large cursor movement and small cursor movement on the same screen only with a mouse in the interactive processing of a computer. CONSTITUTION:The mouse 10 is provided with a variable dial 10c for setting the movement quantity of a cursor. The movement quantity of the mouse 10 is detected by a ball sensor 10d and outputted by a movement detector 12 as count pulses. The set value set with the variable dial 10c is outputted as a multiple value by a multiple generator 14. A multiplier 16 multiplies the count pulse value and multiple value by each other and outputs a control signal for controlling the movement quantity of the cursor to the computer.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen position indicating device, and more particularly to a device for indicating an arbitrary position on a computer display using a mouse.

0002

2. Description of the Related Art Conventionally, a mouse has been known as the most widely used pointing device when performing interactive processing on a computer. By moving the mouse appropriately, the computer operator can move the cursor displayed on the screen and specify any position on the screen.

[0003] Usually, a mouse is equipped with a ball or an optical sensor that detects the amount of mouse movement, and a number of count pulses that are directly proportional to the amount of mouse movement detected by these sensors are output to a computer.
The cursor is moved by an amount proportional to the count.

[0004]The amount of movement of the cursor can be changed by appropriately changing the multiple by which the output count number is multiplied by software on the computer side, or by detecting the movement speed of the mouse and allowing the mouse itself to adjust the count number. This is done by multiplying by a multiple and outputting it to a computer.

[0005]

[Problems to be Solved by the Invention] However, for example, CAD (Computer Aided Design)
) etc., it is necessary to perform both large and small cursor movements on the same screen because the screen is frequently enlarged or reduced.

[0006] However, in the case where the multiplier by which the count number is multiplied as described above is changed by varying it using software, it is necessary to change the software settings each time through interactive processing, and the cursor is reset to the initial position (top left of the screen). There was a problem of low productivity. In addition, in a configuration in which the mouse itself multiplies the count number by a multiple and outputs it depending on the mouse movement speed, the amount of movement of the mouse hand and the amount of movement of the cursor are not proportional, making the operation feel strange. There was a problem that it was not easy to set up.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to easily move a large cursor or move a minute cursor on the same screen, and to reliably move a cursor to any position on the screen. An object of the present invention is to provide a screen position indicating device that can indicate a screen position.

[0008]

[Means for Solving the Problems] In order to achieve the above object, a screen position indicating device according to the present invention includes a detection means for detecting the amount of movement of a mouse and outputting a count pulse according to the amount of movement, and a cursor. A setting means for setting the amount of movement, a multiple generation means for outputting a multiple value according to the amount set by the setting means, and a multiplication means for multiplying the multiple value from the multiple generation means and the count pulse value from the detection means with the mouse. It is characterized by having.

[0009]

[Operation] As described above, in the screen position indicating device of the present invention, the mouse is provided with a setting means for setting the amount of movement of the cursor, and thereby the multiple of the count pulse value is changed to change the amount of movement of the cursor in stages or at no time. This is a step-by-step change.

Therefore, the operator can operate the mouse and set the amount of cursor movement at the same time.
You can easily point to any position on the screen.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the screen position indicating device according to the present invention will be described below with reference to the drawings.

FIG. 2 shows a plan view of the mouse 10 used in this embodiment. As is well known, the mouse 10 is connected to a computer keyboard or computer main body. This mouse 10 is provided with button switches 10a and 10b for performing so-called dragging and clicking, and these button switches 10a and 10b
Dialogue processing can be performed by appropriately operating the .

The mouse 10 is also provided with a variable dial 10c as a setting means for setting the amount of movement of the cursor, and as will be described later, by adjusting this variable dial, the amount of movement of the cursor can be controlled at hand. It is now possible.

Further, a ball sensor 10d is provided at the bottom of the mouse 10 for detecting the amount of movement of the mouse, and the mouse 1 is determined based on the amount of rolling of the ball.
A displacement of 0 is measured.

FIG. 1 shows a block diagram of a screen position indicating device built into this mouse 10. As described above, the amount of movement of the mouse 10 is measured by the amount of rolling of the ball sensor 10d provided at the bottom of the mouse 10, and the movement detector 12 counts pulses in a number directly proportional to the amount of movement of the mouse. Output.

On the other hand, the variable dial 10 is set by the operator.
When c is set to a predetermined value, the multiple generator 14 outputs a multiple value according to this set value based on this set value. Note that, for example, a variable resistor or a variable capacitor can be used as the variable dial 10c. The count pulse from the movement detector 12 and the multiple value from the multiple generator 14 are both input to a multiplier 16 and output to the computer as a control signal for controlling the amount of movement of the cursor.

FIG. 3 shows a block diagram of the structure of the multiplier 16. Count pulses from movement detector 12 are input to counter 16a. On the other hand, this counter 16
For example, a 1 ms clock I is input to a, and pulse values for 1 ms are counted and output to the register I16b. On the other hand, the multiple value from the multiple generator 14 is stored in register II.
16c and held.

Then, the count value held in the register I16b and the multiple value held in the register II16c are outputted to the multiplier 16d, where a multiplication operation is performed. The signal is converted into serial data and output to the computer as a control signal.

In this way, in this embodiment, the multiple value can be appropriately set using the variable dial 10c provided on the mouse, and the amount of movement of the cursor can thereby be changed. It becomes possible to increase or decrease the amount of cursor movement without changing the software, and it becomes possible to easily specify a desired position with the mouse.

[0020]

[Effects of the Invention] As explained above, according to the screen position indicating device according to the present invention, it is possible to easily move a large cursor and a small cursor on the same screen by operating only a mouse. A desired position can be easily and reliably indicated, which has the effect of significantly improving operability.
