Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a pointing device control device used in an input section of a computer.

[Prior art]

For example, processing figures by a computer
In a CAD (Computer Aided Design) system, a mouse is used as a pointing device to indicate a display image or a position on an input figure. Normally, a mouse indicates a position on a graphic using a cursor, so the mouse is moved up, down, left and right, and this movement data is sent to a computer.

FIG. 3 is a circuit block diagram of a control device for supplying data from a mouse to a computer when the mouse as described above is used. The left/right (X direction) and up/down (Y direction) movement amounts of the mouse 1 are supplied to an X direction counter 2 and a Y direction counter 3, and the count data of the X direction counter 2 and Y direction counter 3 is supplied to an X direction adder 4. and is output to the Y-direction adder 5. The X-direction adder 4 and the Y-direction adder 5 combine data from the X-direction reference value memory 6 and Y-direction reference value memory 7, in which reference values in each direction are stored in advance, and data on the amount of movement of the mouse 1 described above. are added and output to the CPU (Central Processing Unit) in the computer as X output and Y output. In addition, the CPU receives the X output from the control device,
The Y output controls the cursor position on the CRT display. The switches 1a and 1b attached to the mouse 1 can be operated when the cursor is set at a predetermined position on the display as described above, and the switches 1a and 1b can output the same switch output.
supplied to the CPU, for example, where the cursor is located
This is a switch that instructs the CPU to display menus on the CRT display.

For example, the procedure for drawing a box shape and a circle on a CRT display using the conventional mouse control circuit as described above will be explained using FIGS. 4a to 4h.

First, as shown in FIG. 2A, initial screen settings such as display of various shape menus 9 are performed on the CRT display 8. Next, in order to draw a box, as shown in FIG. 1B, the cursor 10 is moved to the position where "Box" is displayed in the menu 9, and the aforementioned switch 1a is operated to select "Box". Next, as shown in FIG. 3C, the cursor 10 is moved to a reference position for drawing a box, and the switch 1b is operated to determine the reference point of the box. Next, as shown in figure d, move the cursor 1 for the required box size (the length of the diagonal of the box shape you are trying to create).
0 and operates switch 1b, a box shape with diagonal lines from the reference point to the current cursor 10 position is drawn.

Furthermore, in order to draw a circle, as shown in figure e,
Move the cursor 10 to the position where "circle" is displayed in the menu 9, and select "circle" by operating the switch 1a. Thereafter, the cursor is moved to the reference position for drawing a circle, as shown in FIG. Next, as shown in figure g, the required size of the circle (the length of the radius of the circle to be created)
When you move cursor 10 and operate switch 1b, you can move the current cursor 10 from the reference point (center of the circle).
A circle with a radius up to the position is drawn.

Finally, in order to end the graphic creation process, the cursor 10 is moved to the "end" position in the menu 9, as shown in h of the figure, and the switch 1a is operated.

[Problems with conventional technology]

As mentioned above, when drawing shapes such as boxes and circles on the CRT display, cursor 10 is moved to menu 9.
Because of the movement between the figure and the reference point of the figure, the amount of movement is large as shown by the arrows in FIGS. 4b to 4h. Furthermore, the aforementioned X output and Y output as the movement data of the cursor 10 are simply added by the amount of movement in each direction according to the movement of the mouse 1 by the X direction addition circuit 4 and the Y direction addition circuit 5. Therefore, the amount of movement of the cursor 10 mentioned above is proportional to the amount of movement of the mouse 1, and the operator of the mouse 1 must similarly move the mouse 1 in proportion to the amount that the cursor 10 moves on the CRT display. As a matter of fact, the operability of the mouse 1 was poor.

This moves the cursor 24 to the box position without moving the mouse. Thereafter, move the cursor 24 to the "circle" position in the menu 24 by operating the mouse 11, and select "circle" by operating the switch _S2 .

Thereafter, in order to move the cursor ₂₅ to the reference point of the circle _to be created as shown in FIG. A memory read signal C is output to. By this operation, the data m _X2 and m _Y2 indicating the position of corner 25' of the box stored in the second memory area as described above is output to the CPU. Therefore, the cursor 25 is first moved to position 25'. Furthermore, the reference point (center point) of the circle can be determined by moving the cursor 25 to the reference position for drawing a circle and operating the switch _S2 .

Next, as shown in figure g, move the cursor 25 by the required size of the circle (the length of the radius of the circle) using the mouse 11.
A circle is drawn by moving and operating switch _S2 .

Finally, in order to end the graphic creation process, move the cursor to the "end" position in the menu 24 and operate the switch, as shown in h of the figure.

In this case as well, the cursor 24 can be moved once to the position of the "box" in the menu 24 by operating the switch _S5 in the same way as described above, and then operating the mouse 11 to move it to the "end" position in the menu 24. Move to.

As described above, when a box shape and a circle are drawn using the mouse control device of this embodiment, compared to FIGS. The distance that must be traveled is much shorter as shown in Figures 2b-h than in Figures 4a-h, which depict the same figure.
