Abstract

PROBLEM TO BE SOLVED: To eliminate the need of switch operation of a mechanical switch at the time of switching the input systems of two kinds of moving instructions. SOLUTION: In this input device using a touch panel 3 for controlling the instruction marks such as a pointer and a cursor which are displayed on a display screen, two systems, namely the system by which the shift instruction is inputted and the cursor is relatively shifted by adjusting it to the locus of shift while the cursor is shifted by an input pen and a finger on the touch panel, and the system by which the shift instruction is inputted by depressing one arbitrary point on the touch panel for prescribed time, them the direction and the distance of a depression point against the center point 4 of the touch panel are obtained. The two input systems for moving the cursor at shift speed corresponding to the obtained direction and distance are switched by the length of depression time against one arbitrary point on the touch panel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an input device, and more particularly to an input device for controlling a pointer, a cursor, and other indicating symbols displayed on a display screen in an information processing device.

[0002]

2. Description of the Related Art Generally, a personal computer, a workstation, and an image processing apparatus require a movement command input device for moving an instruction symbol such as a cursor or a pointer on a screen. At present, there are the following two types of input devices using a touch panel in this type of input device.

One is a method in which a movement command is input by moving the touch panel while pressing it with an input pen or a finger, and the cursor is relatively moved in accordance with the trajectory of the movement of the finger.

The other is to input a movement command by pressing an arbitrary point on a touch panel for an arbitrary time as described in Japanese Patent Application Laid-Open No. 63-73415. There is a method in which the direction and distance of the pressed point are determined, and the cursor is moved in the determined direction at a moving speed corresponding to the distance while the cursor is continuously pressed.

[0005]

As described above, in the conventional method of inputting the amount of movement by moving the touch panel while pressing it with a finger or the like, the finger is moved in one direction when the cursor is moved many times. You have to repeat the work to make it many times.

On the other hand, if the ratio of the movement of the cursor to the amount of movement input by a finger or the like is increased to solve this problem, the accuracy of input of the amount of movement will deteriorate.
Further, the method of pressing the touch panel with a finger or the like for an arbitrary time and inputting a movement command according to the direction and distance between the pressed point and the center point of the touch panel is rare when the cursor is moved many times in one direction. On the other hand, the amount of movement can be input with effort. On the other hand, as shown in FIG. Since the moving path b of the cursor on 2 is different, it is very difficult to draw a figure.

Further, when the two types of movement command input methods are switched and used, a switching operation such as switching with a mechanical switch is required.

[0008]

According to the present invention, there is provided an input device using a touch panel for controlling a pointing symbol such as a pointer and a cursor displayed on a display screen. A method of inputting a movement command by moving while pressing while moving the cursor relative to the trajectory of the finger movement,
A movement command is input by pressing an arbitrary point on the touch panel for an arbitrary time, a direction and a distance of the pressed point with respect to a center point of the touch panel are determined, and a cursor is determined in the determined direction and according to the distance. The two input methods of moving at the moving speed are switched according to the length of the pressing time for an arbitrary point on the touch panel.

According to the present invention, two types of input methods for moving the cursor can be switched and used without performing a special operation, so that the number of input operations for moving the cursor can be reduced.

[0010]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the input device of the present invention, and FIG. 2 is a diagram showing an input of a movement command by moving the touch panel of the present invention while pressing it with an input pen or a finger. FIG. 3 is a diagram showing an embodiment in which a movement command is input by pressing an arbitrary point on the touch panel of the present invention, and FIG. 5 is a flowchart showing the operation of the embodiment of the input device of the present invention.

FIG. 1 has a touch panel 3 for inputting a command to move the cursor on the display screen up, down, left and right by pressing the touch panel 3 with a finger or the like.

A process when a movement command is input to the touch panel 3 will be described with reference to FIGS.

The touch panel 3 shown in FIG.
Is provided. It is confirmed at a fixed interval whether or not the touch panel 3 is being pressed by a finger or the like (step S1). If the pressing is confirmed, the reception of an input is started (step S1 YES). When the touch on the touch panel 3 is confirmed (step S1 YES), the coordinates of the pressed position are detected (step S2), and the detected coordinates are verified for a change in the pressed position (step S2).
4).

When the user moves while pressing with a finger or the like between the input point P1 and the input point P2 on the touch panel 3, a change in the pressed position coordinates is confirmed in the verification of the pressed coordinates (step S4 YES), and the detection is performed. X direction and Y
The amounts of change in the directions are set as X1 and Y1, respectively (step S6), and the amount of movement of the cursor is calculated by multiplying X1 and Y1 by a constant Z (step S7), and the calculation result is output as a movement command. (Step S8).

When the input point P3 on the touch panel 3 is pressed for an arbitrary time, no change is confirmed in the pressed position coordinates in the verification of the pressed coordinates (step S4NO). It performs (Step S10), and verifies the measured pressing time and a specified time as a reference for switching the input method of the cursor movement command (Step S11).

In the verification of the measured pressing time, when it is determined that the pressing time has exceeded the specified time (step S1).
1 YES), the coefficients X3 and Y3 of the movement amounts in the X and Y directions are set based on the angle θ of the input point P3 on the touch panel 3 with respect to the center point 4 of the touch panel 3 (step S1).
2) The amount of movement of the cursor is calculated by multiplying the coefficients X3 and Y3 by the distance L between the center point 4 of the touch panel 3 and the input point P3 on the touch panel 3 (step S1).
3) Output the calculation result as a movement command (Step S)
8).

If the pressing time does not exceed the specified time in the verification of the pressing time (NO in step S11),
After the output of the cursor movement command (step S7), the current pressed position is stored as coordinate movement verification data (step S14), and the process returns to the confirmation of the pressing on the touch panel 3 (step S1).

By this operation, it is possible to switch the input method of the two kinds of different cursor movement commands by the pressing time on the touch panel, so that the operability of the cursor can be improved.

[0020]

According to the present invention, when inputting a command to move the cursor displayed on the display screen, the user moves the cursor by pressing the touch panel with an input pen or a finger while inputting the command to move the cursor. With a method that moves relatively to the trajectory, a movement command is input by pressing an arbitrary point on the touch panel, the direction and distance of the pressed point with respect to the center point of the touch panel are determined, and the cursor is determined. Since a system that moves in a given direction and at a moving speed corresponding to the distance can be switched and used without performing a special operation, an input operation for moving a cursor can be reduced.
