2. Description of the Related Art Conventionally, there are the following methods for moving a cursor on a display screen of a visible display device of a computer system by using a mouse type pointing device (hereinafter also referred to as a mouse). That is, the amount of movement of the mouse on the operation plane is measured by measuring the rotation of the ball with an encoder, by measuring the duration of the friction sound during movement, or by optically reading the mark on the operation plane and measuring the movement. Based on the amount, data for instructing the movement of the cursor on the display screen is converted and generated at a constant conversion rate. Also, if it is difficult to operate the mouse at a certain conversion rate, select the switch attached to the mouse to change the conversion rate of the above data conversion and change the effectiveness of the movement amount of the mouse. There is.

[0003]

In the above-mentioned conventional method, when the movement of the cursor on the display screen is large, it is necessary to increase the movement of the mouse on the operation plane or increase the number of movements. Also, it was necessary to move the mouse finely for the thin movement of the cursor. Therefore, it is difficult to operate the mouse according to the large movement and the thin movement of the cursor. Moreover, in order to reduce the difficulty, the mouse provided with the above-mentioned switch for changing the effect of the amount of movement of the mouse is complicated to select each switch.

An object of the present invention is to change the conversion rate for converting the movement of a mouse type pointing device into the movement of a cursor on a display screen in a stepwise manner in accordance with the pressure with which the mouse is pressed, and to make a large movement of the cursor on the display screen. It is intended to improve the operability of the mouse type pointing device by adapting to both thin movements.

According to another aspect of the present invention, there is provided a computer system including a computer, a mouse type pointing device and a visual display device, a movement amount detecting means for detecting a movement amount moving on an operation plane, and The mouse-type pointing device includes pressure detection means for detecting pressure to be pressed against the operation plane, movement data conversion means for converting the movement amount into movement data, and pressure data conversion means for converting the pressure into pressure data. Any one of the mouse-type pointing device and the computer is provided with a control means that is provided and that converts the movement data stepwise according to the pressure data when converting the movement data into data for instructing movement of a cursor on the display screen of the visual display device. It is provided in the crab.

Mobile data conversion unit 4 for converting respectively
And a pressure data conversion unit 5 and a control unit 6 for converting movement data into data instructing movement of a cursor on the display screen of the visual display device 8 stepwise according to the pressure data. The movement amount detection unit 2 indicates the movement amount as a digital value by rotating the encoder disk by the rotation of the ball. The pressure detection unit 3 converts the pressure applied to the operation plane into the flexure of the spring, measures the flexure, and shows the digital value. Converter 4, 5
Converts the digital value of the movement amount of the movement amount detection unit 2 and the digital value of the pressure of the pressure detection unit 3 into movement data and pressure data of an electric signal capable of data processing, respectively.
The control unit 6 for converting the movement data into the data indicating the movement of the cursor on the display screen according to the pressure data is the mouse 1
Built in. The output data of the control unit 6 is data for instructing the movement of the cursor on the display screen of the visual display device 8,
The interrupt signal 9 is read by the computer 7 via the signal cable 10. Interrupt signal 9 is mouse 1
Is detected by the conversion unit 4 and is generated.

Referring to FIG. 2 showing the detailed structure of the control unit 6, the moving data register 11 for storing the moving data on the moving data line 14 and the pressure data register 12 for storing the pressure data on the pressure data line 15 are described. The data to be calculated is input to the calculation circuit 13. The arithmetic circuit 13 converts the pressure data of the pressure data register 12 into three stepwise conversion rates of large, medium and small. FIG. 3 shows an example of the relationship between the pressure data and the conversion rate. Further, the arithmetic circuit 13 multiplies the conversion rate by the movement data and outputs it as data instructing the movement of the cursor to the computer 7. FIG. 4 shows an example of the relationship between the amount of movement and the movement of the cursor according to the conversion rate.

Next, referring to FIG. 5 showing the configuration of another embodiment of the present invention, the above-mentioned control unit 6 is constituted by a control program 17 provided in the computer 7. The output data of the movement data conversion unit 4 and the pressure data conversion unit 5 are transferred to the computer 7 by the interrupt signal 9 via the signal cable 16.
Read by. The control program 17 is activated by an interrupt signal 9 sent to the computer 7 by moving the mouse 1. The activated control program 17 reads the pressure data from the conversion unit 5 (procedure 21), and converts the pressure data into large, medium and small conversion rates (procedure 22). Next, the movement data is read from the conversion unit 4 (procedure 23). The read movement data is multiplied by the conversion rate from the pressure data (procedure 24), data for instructing the movement of the cursor is generated from the multiplication result (procedure 25), and the process ends. The computer 7 receives the data instructing the movement of the cursor from the control program 17, and moves the cursor on the display screen of the visual display device 8.

According to the above-described embodiment, when the operator largely moves the cursor on the screen, the pressure to press the mouse perpendicularly to the operation plane is strengthened so that the cursor on the display screen moves in the desired direction. Move up. Even when the place to move the mouse is small and it is difficult to operate the mouse, the operator can move the cursor largely by increasing the pressing force of the mouse to move the mouse. When the operator wants to move the cursor on the screen finely, the operator can move the cursor finely by weakening the pressing force of the mouse and moving the cursor on the operation plane.

In the movement amount detecting section 2 described above, the mouse 1
Either of the structure of measuring the duration of the fricative noise during movement on the operating surface and converting it to a digital value, and the structure of optically reading and counting the markers marked on the operating plane and converting it to a digital value are adopted.
