JPS6180421A - Cursor shift control system using mouse - Google Patents

Abstract

PURPOSE:To decrease the size of a mouse pad by setting the mouse shift speed in proportion to a low speed of a cursor when the mouse shift speed exceeds a set low speed and keeping a high cursor shift speed even in case the mouse shift speed is reduced suddenly after it exceeds a set high speed. CONSTITUTION:When a mouse 5 moves, a ball 11 revolves to output pulses through X and Y axis pulse generators 13 and 12. These pulses are counted by X and Y axis counters 15 and 14 respectively. A timer 16 applies interruptions to a controller 2 via an interface circuit 17 for each fixed period of time and sends the contents of each counter to the controller 2. The controller 2 sets the cursor shift speed in proportion to the mouse shift speed when this speed exceeds a set level XB. Thus the cursor shift speed is held at a high level even in case the mouse shift speed exceeds a set level XA and reduced suddenly. When the mouse shift speed exceeds the level XB from a stationary or quasi-stationary state, a high-speed shift mode of the cursor is released.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cursor movement control method using a mouse that allows the cursor to move at a speed proportional to the speed before the mouse stops even when the mouse is stopped. It is.

[Prior art and problems]

FIG. 5 is a diagram showing an example of an image processing system. Fifth
In the figure, 1 is a display, 2 is a controller, and 3 is a display.
indicates a keyboard, 4 indicates a mouse pad, and 5 indicates a mouse. The controller 2 is composed of a promoter, for example, and performs graphic processing according to human input from the keyboard 3 and mouse 5. A mouse 5 is placed on the mouse pad 4, and moving the mouse 5 moves the cursor on the display screen.

FIG. 6 shows the relationship between windows and logical screens. In FIG. 2, W indicates a window and LD indicates a logical screen. In this case, it may be considered that the window W has a one-to-one correspondence with the entire screen of the display 1, and the figure within the logical screen area surrounded by the window W is displayed on the display screen. When the mouse 5 is moved while the cursor is in contact with the side of the window W, the window W moves within the logical screen LD. Thereby, a figure at an arbitrary position on the logical screen LD can be displayed on the display screen.

FIG. 7 is a diagram showing the relationship between the mouse movement speed and the cursor movement speed on the display screen in the conventional method. In FIG. 7, ■ indicates the moving speed, nickel indicates the time, the solid line indicates the mouse moving speed, and the dotted line indicates the cursor moving speed. In the conventional technology, the ratio of mouse movement speed to cursor movement speed is 1:1 or 1:N (N is a positive number).
Met.

Additionally, the ratio of the mouse movement speed to the cursor movement speed is changed in stages according to the speed.

In the conventional method, if you want to display a wide logical screen in a window, you cannot position the window at the desired position on the logical screen unless you move the mouse repeatedly from one end of the mouse pad to the other. Can not.

[Objective of the Invention 3] The present invention is based on the above considerations, and is an object of the present invention to enable accurate and high-speed cursor movement using a mouse with fewer mouse movements in an information processing system such as a graphic processing system or an image processing system. The purpose of this project is to provide a method for controlling cursor movement using a mouse.

[Means to achieve the purpose]

Therefore, the cursor movement control method using a mouse of the present invention includes a display, a mouse, and a controller, and when the mouse is moved, the cursor on the display screen is moved under the control of the controller. In the information processing system, the controller moves the cursor in proportion to the mouse movement speed when the mouse movement speed exceeds the low speed setting value, and moves the previous mouse when the mouse movement speed becomes smaller than the low speed setting value. When the movement speed is higher than the high speed setting value, the cursor movement speed is kept in a high speed state, and when the mouse movement speed changes from a stationary or semi-stationary state to a value higher than the low speed setting value, the cursor is kept in a high speed state. It is characterized in that it is configured to be released.

[Embodiments of the invention]

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing an outline of a mouse. In Fig. 1, 11 is a ball, 12 is a Y-axis pulse generator, 13 is an X-axis pulse generator, 14 is a Y-axis counter, 15 is an X-axis counter, 16 is a timer, and 17 is an interface circuit. . When the mouse 5 moves, the ball 11 rotates. When the ball 11 moves, a pulse is output from the X-axis pulse generator 13 and/or the X-axis pulse generator 12.

Pulses from the X-axis pulse generator 13 are sent to the X-axis counter 15
The pulses from the X-axis pulse generator 12 are counted by the Y-axis counter 14. The timer 16 interrupts the controller via the interface circuit 17 at fixed time intervals (for example, every 20 m5), sends the contents of the X-axis counter 15 and the Y-axis counter 14 to the controller 2, and outputs the contents of the X-axis counter 15 and Y-axis counter 14. Reset to O.
