Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a data input device for moving a cursor position on a display screen such as a CRT.

[Technical background of the invention]

2. Description of the Related Art In information processing devices such as personal computers, word processors, and video game devices, displays are used to input data, confirm content, and the like. There are various methods for moving the cursor position on a display screen, such as using cursor keys and moving sticks, but in recent years, a pointing device called a mouse has been widely used.

Hereinafter, the conventional device will be explained with reference to FIGS. 5 to 7 of the accompanying drawings. In the following description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.

FIG. 5 is a perspective view of a data input device using a pointing device called a mouse. Table 1 includes data input device main body (information processing device) 2
is installed. On the front of the information processing device 2
A CRT display 3 is arranged, and a cursor 4 is displayed here. Further, a keyboard 5 is provided at the front of the information processing device 2, so that data can be input to an internal control section (not shown).
A pointing device (mouse) 6 is connected to the control section of the information processing device 2 via a cord 7, and can be freely moved on a pad 8 on the table 1.

FIG. 6 is an internal configuration diagram of the apparatus shown in FIG. 5. Main ball 11 is padded 8 on table 1
It comes into contact with the body and rotates freely according to the movement of the hand. Rotation of the main ball 11 in the X direction is transmitted to the sub ball 12, and rotation in the Y direction is transmitted to the sub ball 13. The X-direction movement amount detector 14 and the Y-direction movement amount detector 15 detect the amount of rotation of the sub-balls 12 and 13, respectively.
These detected values are converted into digital quantities by A/D converters 16 and 17. And the digital signal is
The signal is given to the control unit 18 of the information processing device 2 as a direction movement amount signal and a Y direction movement amount signal. The control section 18 includes a support section for instructing the movement of the cursor 4 on the display screen 3 in accordance with the X and Y direction movement amount signals.

FIG. 7 is an explanatory diagram of the operation of the apparatus shown in FIGS. 5 and 6. Suppose now that the cursor on the display screen 3 is moved from the position 4a to the position 4b in the figure. In this case, the mouse may be moved by hand from the position 6a to the position 6b in the figure. Furthermore, when moving the cursor from the position 4b to the position 4c in the figure, the mouse can be moved from the position 6b to the position 6c. In this way, the operator can easily instruct the cursor to move by moving the mouse in the desired direction by the desired amount, depending on the desired direction and amount of movement of the cursor.

[Problems with background technology]

However, in the conventional device as described above, the mouse must be moved by an amount corresponding to the amount of movement of the cursor.
The operator must move the mouse manually. Therefore, when inputting a large amount of data of various types, the operator must move the mouse busily. This has the disadvantage that it imposes a burden on the operator, resulting in a decrease in data input efficiency.

[Purpose of invention]

The present invention has been made in order to overcome the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a data input device that enables quick and easy movement of a cursor on a display screen using a pointing device called a mouse. With the goal.

[Summary of the idea]

In order to achieve the above object, the present invention uses a pointing device (mouse) that moves freely on a flat plate such as a table or pad according to the movement of the hand.
A data input device that moves the cursor position on a display screen such as a CRT is equipped with a detection means that outputs a pressure signal corresponding to the pressure that the pointing device receives from the flat plate, and the movement amount signal is output by an integrator according to the pressure signal. The present invention provides a data input device that instructs movement of a cursor position on a display screen using a correction movement signal that performs multiplication processing by a magnification and causes a change in cursor movement amount due to the multiplication.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4 of the accompanying drawings.

FIG. 1 is a perspective view of a mouse according to the same embodiment. Two operation buttons 21 and 22 are provided on the top surface of the mouse 6 as a pointing device, and a pressing member 23 is provided on the bottom surface. This pressing member 23 is adapted to slide on the pad 8, and for this purpose, for example, a number of freely rotating balls are embedded therein. When the operator manually pushes the pointing device (mouse) 6 constructed as described above in the direction of the arrow in the figure, the pressing member 23 is moved upward by pressure from the pad 8. This movement of the pressing member is detected by a pressure sensor 24 provided inside. The above pressing member 2
3 and the pressure sensor 24 constitute a second detection means.

FIG. 2 is an internal configuration diagram of the data input device using a mouse shown in FIG. 1. The difference between this and the conventional one shown in FIG. 6 is that the mouse 6 is provided with a pressure sensor 24 and an A/D converter 25.
A multiplier 26 as a correction means is provided in the control section 18. The pressure sensor 24 is the first
It detects the pressure applied to the pressing member 23 shown in the figure and outputs an electrical signal according to the pressure. This analog electrical signal is converted into a digital magnification signal (pressure signal) by the A/D converter 25. The multiplier 26 multiplies the movement amount signal in the X direction by the magnification signal, and also multiplies the movement amount signal in the Y direction by the magnification signal. These multiplication results are sent as a corrected movement amount signal to an instruction section in the control section 18, which instructs movement of the cursor position on the display screen 3.

FIG. 3 is a side view illustrating how the mouse shown in FIG. 1 is operated by an operator. The operator holds the mouse 6 on the pad 8 as shown. At this time, the operation buttons 21 and 22 are operated with the index finger and middle finger, and the mouse 6 is pressed down lightly with the whole hand. That is, the pressing member 23 is pressed against the pad 8. In this way, the mouse 6 is moved on the pad 8 to indicate the cursor position.

FIG. 4 is an explanatory diagram of the operation of the embodiment shown in FIGS. 1 to 3. Assume that the mouse indicated by reference numeral 6d in FIG. 4b is moved to a position indicated by reference numeral 6e without applying any pressure to the pressing member 23. At this time, no electrical signal is output from the pressure sensor 24, and therefore the movement amount signal in the X and Y directions is not corrected by the multiplier 26. As a result, the cursor on the display screen is marked 4d in Figure 4a.
It will move from the position shown in 4e to the position shown in 4e.

On the other hand, regarding the mouse shown with reference numeral 6f in FIG. 4b, pressure is applied to the pressing member 23 to
Suppose that it is moved to the position indicated by g. At this time, the pressure sensor 24 outputs an analog signal having a magnitude corresponding to the applied pressure, which is converted into a digital magnification signal and provided to the multiplier 26 . Now, if this magnification signal indicates 3 times, the movement amount signals in the X and Y directions are each multiplied by 3 times by the multiplier 26. As a result, the cursor on the display screen moves from the position shown at 4f in FIG. 4a to the position shown at 4g. That is, the amount of movement of the cursor can be tripled by the pressure applied to the pressing member 23, for example.

The present invention is not limited to the above.
For example, a display device that displays a cursor is
It is not limited to a CRT, but any device that visually displays data may be used, such as a liquid crystal display, an electroluminescent display, or a plasma display. Further, the pointing device is not limited to one that can be moved on a pad, but may be one that can be moved on a table on which a display device is installed.

The data exchange between the pointing device and the information processing device is not limited to the wired method using a code as in the embodiment.
A cordless type using ultrasonic waves as shown in the above publication may also be used. Furthermore, the detection of the amount of movement and the direction of movement is not limited to the method used in the embodiment using a ball that rotates in contact with a pad, but can also be performed using optical means such as that disclosed in Japanese Patent Laid-Open No. 59-98242. It may be something that was there.

Furthermore, the pressing member that applies pressure may be configured to receive pressure directly from the pad as in the embodiment, but may also be configured to receive pressure from the main ball.

[Effect of idea]

As described above, in this invention, the pointing device detects the pressure received from a flat plate such as a pad, corrects it by multiplying the movement amount signal by a multiplier according to this pressure, and uses this corrected movement amount signal to display the display. Since the instruction is to move the upper cursor position, the cursor movement amount is multiplied by the movement magnification according to the pressure, and the cursor movement amount can be continuously changed in magnification according to the pressure. A data input device is obtained in which the cursor can be moved over long distances by moving the distance, and the cursor can therefore be moved quickly and easily. It can provide the operator with a continuous cursor movement speed adjustment function that adapts to continuous changes in the pressure applied to the bottom of the pointing device, encouraging the operator to operate smoothly and improving the man-machine interface. It has the advantage of being able to achieve
