JPH05204547A - Cursor position controller - Google Patents

Abstract

PURPOSE:To easily and accurately move and determine the position of a cursor by providing at least two pointing devices(PD) and using one for cursor long- distance movement and using the other for cursor short-distance movement. CONSTITUTION:Whether a move instruction is inputted from the first PD or from the second PD is discriminated. In the case of input from the first PD, the input is substituted for X and Y. A cursor 8 is moved to the X, Y coordinate position corresponding to values of substituted X and Y. In the case of input from the second PD, the input is substituted for (x) and (y). The cursor 8 is moved to the x, y coordinate position corresponding to values of substituted (x) and (y). X and Y are the extent of movement of the cursor 8 due to the move instruction of the first PD, and (x) and (y) are that due to the move instruction of the second PD. When one point is pointed by the cursor 8, a user first moves the cursor 8 to a certain position by the PD for long-distance movement and next moves it to the accurate position by the PD for short- distance movement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cursor position control device for controlling the position of a cursor displayed on a graphic screen display device or the like.

[0002]

2. Description of the Related Art Conventionally, a cursor position control device moves a cursor on the screen of a graphic screen display device according to the upward, downward, left, and right movement information from one pointing device to determine its movement position. Is configured to control.

[0003]

However, in the above conventional device, as the screen resolution of the graphic screen display device becomes higher, one pixel on the screen is controlled by the pointing device to set the cursor to one point. It will be difficult.

When the cursor is moved for a long distance, the pointing device must be moved for a long distance.

Further, even if the cursor can be set at one point with the pointing device, it has a drawback that an erroneous input is likely to occur due to mechanical shake because it reacts to a slight movement of the pointing device.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cursor position control device capable of easily and accurately determining the position of a cursor.

[0007]

To achieve the above object, a cursor position control device of the present invention is a cursor position control device for controlling the position of one cursor displayed on a screen display device from a pointing device using movement information. In at least two of the pointing devices, the moving distance of the cursor according to the moving information from each pointing device is different from each other.

[0008]

With one of the at least two pointing devices for moving the cursor long distance and the other one for moving the cursor short distance, the position of one cursor is controlled by the movement information from these pointing devices. By doing so, the position of the cursor can be easily moved and determined.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block configuration diagram of a computer system having a cursor position control device according to the present invention. In FIG. 1, 1 is a graphic screen display device and 2 is a CP.
U (Central Processing Unit), 3 is a memory, 4 is a system bus, 5 is a pointing device controller, 6 is a first pointing device, and 8 is a second pointing device.

First and second pointing devices 6,
The pointing device controller 5 receives a movement command (movement information) on the plane input from the CPU 7, and the CPU 2
Let me know. First and second pointing devices 6,
The movement commands input from 7 are equivalent to each other.

Next, the control processing procedure performed by the CPU 2 based on the movement command of the first and second pointing devices 6 and 7 will be described with reference to the flowchart of FIG.

When the movement command α from the first and second pointing devices 6 and 7 is a command to move in the X direction, the movement command from the first pointing device 6 is X = nα. Become. Further, the movement command from the second pointing device 7 is X = α.

However, n is a natural number, and the value of this n is CP.
It can be freely set by U2.

In FIG. 2, when the control operation is started, first, in step 1, it is determined whether the movement command is an input from the first pointing device 6 or an input from the second pointing device 7. The answer is affirmative (YES),
That is, in the case of the input from the first pointing device 6, the process proceeds to step 2 and the input from the first pointing device 6 is substituted for X and Y. Then, in step 3, the cursor is moved to the X, Y coordinate position corresponding to the X, Y value substituted in step 2, and then the process returns to step 1.

On the other hand, if the answer to step 1 is negative (NO), that is, if the input is from the second pointing device 7, the process proceeds to step 4, where the input from the second pointing device 7 is set to x, y. substitute. Next, in step 5, the cursor is moved to the x, y coordinate position corresponding to the x, y value substituted in step 4, and then step 1
Return to.

FIG. 3 is a diagram showing a cursor movement state on the screen of the graphic screen display device 1, in which X and Y are movement amounts of the cursor 8 according to a movement command of the first pointing device 6, x, and Y, respectively. y is the amount of movement by the movement command of the second pointing device 7.

By performing such processing, the first
With the input from the pointing device 6, the cursor 8 moves a long distance, and with the input from the second pointing device 7, the cursor 8 moves a short distance.

In the above embodiment, the case where two pointing devices are provided has been described, but the present invention is not limited to this, and two or more pointing devices may be provided.

Further, although the screen of the graphic screen display device is explained as the control of only the plane of the second limit, X, Y, x, y, it is not limited to this, and the space of the third limit, that is,
The same control can be performed for X, Y, Z, x, y, and z.

[0021]

As described above, according to the cursor position control apparatus of the present invention, the functions of the plurality of pointing devices are divided into those for moving the cursor over a long distance and those for moving the cursor over a short distance, and each of these pointing devices is used. Since the movement of one cursor is controlled by the user, when a certain point is indicated by the cursor, the user first moves the cursor to a position that is a pointing device for long-distance movement, and then a pointing device for short-distance movement. The device can move the cursor to a precise position, and thus the position of the cursor can be easily and accurately determined.
