Abstract

PURPOSE:To improve the operability by varying a moving speed of a cursor in accordance with whether a selection picture or a selection table is coarse or dense. CONSTITUTION:A CPU 5 always stores a position of a cursor 11 on a display 6 and the contents of a picture and changes a speed of a position movement in the X and the Y directions from a mouse driver 4 in accordance with a position of the cursor 11. Even if a signal of the same frequency is received from the mouse driver 4, the moving speed of the cursor 11 becomes low as it goes to the right in order of A, B and C in accordance with whether the display screen is coarse or dense.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pointing mechanism for operating a screen of a computer or the like.

[Prior Art] Conventionally, a mechanism for selecting an arbitrary item by moving a cursor on the screen of a computer, etc. has been to move the cursor to an arbitrary position using up and down cursor keys on a keyboard, a mouse, etc. After that, ``I was supposed to turn on keys such as return j.

[Problems to be Solved by the Invention] However, cursor movement is generally performed by subroutine software for cursor movement, and the movement speed is constant. Therefore, if the selection items on the screen are arranged in detail, or if you want to freeze the selection at the desired position,
It sometimes moved too much, and it took a lot of effort to stop it in the required position.

The present invention was made to solve the above-mentioned problems, and actually
The cursor movement software routine is designed to change the movement speed of the cursor and reduce the movement speed when the cursor enters an area where many selection items are densely displayed.

Even in areas where selection items are displayed in detail, the cursor can be made to stand still at any position without moving too much, making selection operations easier.

[Means for Solving the Problem] In order to achieve this object, the pointing mechanism of the present invention uses a display device such as a CRT, a memory storing software for processing the displayed image, or an electronic circuit for processing the displayed image. An image processing circuit was installed to change the speed of movement of the cursor on the screen depending on the content displayed on the screen and the position on the screen.

The cursor position is memorized, and when an instruction to move the mouse, cursor key, etc. is received, the cursor movement speed is arbitrarily changed by software or pulse control for movement, depending on the screen content and the cursor position.

[Example] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

FIG. 1 is an example of a mouse as a pointing device. Figure 2 shows the block surface that has been realized using the mouse, and by rotating the ball 7 in the X and Y directions,
, the pulse is detected by the Y-direction detection pulse generator 8.9. The pulses for movement in the X and Y directions are generated by the mouse driver 4. The cursor on the display 6 is moved via the CPU 5.

At this time, the pulse control circuits 2 and 3 receive feedback from the CPU 5 according to the position of the cursor 11 on the display 6 to control the generation of pulses for movement. FIG. 3 shows an example in which the actual operation is implemented using software, in which the CPU 5 always remembers the position of the cursor 11 on the display 6 and the screen contents, and controls the speed of position movement in the X and Y directions from the mouse driver 4. Software is built into the memory within the CPU 5 so that it can be changed arbitrarily according to the position of the cursor 11. Fig. 4 shows an example in which the present invention is specifically adopted in a FAX center machine, and Fig. 5 shows an example in which items are selected by moving the cursor using mouse 1 on the CRT of the center machine. be.

In the diagram above, moving speed becomes slower as the area goes from A-B to C to the right.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, in the task of continuing operations while selecting items on the display screen, in the portion where the selected items are expressed in detail, I had to repeatedly move over and it took a lot of time to make a selection, but in reality it was a smoother operation.
