Abstract

<P>PROBLEM TO BE SOLVED: To prevent erroneous operation when the fingers of an operator slip and touch a button adjacent to a desired button in a touch panel. <P>SOLUTION: When a touch panel 4 is touched, a button corresponding to a touch position is recognized (a step S1). Then the flag of a button adjacent to the button is turned into "operation invalid" (a step S2), and the timer of the button turned into "operation invalid" is started (a step S3). Subsequently, the flag of the button recognized in the step S1 is referred to. If the flag is "operation valid", the recognized button is validated (a step S4 to S5). If the flag is "operation invalid", the button is invalidated (step S4 to S6). Also, when the timer started in the step S3 elapses for a given time that the fingers of the operator seems to slip and touch the button adjacent to the desired button, for example 100 msec, the flag is reset to "operation valid". <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a touch panel device that displays a plurality of buttons on a display screen and recognizes that a button corresponding to a touch position of the touch panel superimposed on the display screen has been operated, and a computer program thereof.
[0002]
[Prior art]
Generally, the touch panel is superimposed on the display screen, and when the operator touches the button displayed on the display screen and touches the touch panel at the position of the button, it is detected that the button corresponding to the touch coordinates is pressed. are doing.
[0003]
[Problems to be solved by the invention]
However, in the conventional example, since all the buttons at the position where the touch panel is touched are enabled, when a plurality of buttons are displayed side by side, after the operator touches a desired button, the finger slips and touches an adjacent button. In this case, there is a problem that both buttons are enabled and the button operation intended by the operator is not performed.
[0004]
The present invention has been made in view of the above-described problems of the related art, and has an object to provide a touch panel device capable of preventing an erroneous operation when an operator's finger slides and touches a button adjacent to a desired button, and a computer program thereof. And
[0005]
[Means for Solving the Problems]
The touch panel device of the present invention and a computer program thereof are provided in order to achieve the above object.
When recognizing that the predetermined button has been operated, the button operation at least adjacent to the predetermined button whose operation has been recognized is invalidated for a predetermined time, and it is determined whether the button operation whose operation has been recognized is valid or invalid. The button operation is enabled or disabled on the basis of.
According to the above configuration, when the operator's finger slides and touches a button adjacent to a desired button, the adjacent button is invalidated, so that an erroneous operation can be prevented.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of a touch panel device according to the present invention, FIG. 2 is an explanatory diagram showing an example of a display button, and FIG. 3 is a flowchart for explaining operation button processing of the microcomputer of FIG. .
[0007]
1, the LCD driver 1 displays images such as buttons # 1 to # 4 shown in FIG. 2 on the screen of the LCD display device 2, and the touch panel driver 3 is superimposed on the screen of the LCD display device 2. The touched position of the touch panel 4 is detected. The microcomputer 5 determines which button has been operated based on the button position displayed on the screen of the LCD display device 2 by the LCD driver 1 and the touch position of the touch panel 4 detected by the touch panel driver 3. Perform control according to. Note that the process of detecting the touch position of the touch panel 4 may be performed by the microcomputer 5 instead of the touch panel driver 3.
[0008]
Next, an operation button detection process of the microcomputer 5 will be described with reference to FIG. First, when the touch panel 4 is touched, the button corresponding to the touched position is recognized (step S1), the flag of the button adjacent to the button is set to “operation invalid” (step S2), and then the operation is set to “operation invalid”. The timer of the pressed button is started (step S3). Next, the flag of the button recognized in step S1 is referred to, and if the flag is “operation valid”, the button whose operation has been recognized is then validated by valid processing (step S4 → S5), while the flag is “operation invalid”. Is invalidated by invalidation processing (step S4 → S6).
[0009]
The validity processing in step S5 means that a touch panel interface (not shown) treats the operation of the button as valid, that is, each button which is an on / off switch is in an on state (conductive state) for a predetermined time. On the other hand, the invalidation processing in step S6 means that the touch panel interface treats the button as being in an off state (non-conduction state). When the timer started in step S3 elapses a predetermined time, for example, 100 msec, at which the operator's finger slips and touches a button adjacent to the desired button, the flag is reset to “operation valid”. Further, by invalidating the button operation for a predetermined time after the adjacent button is separated from the touch panel, erroneous operation can be prevented.
[0010]
【The invention's effect】
As described above, according to the present invention, when an operator's finger slides and touches a button adjacent to a desired button, the operation of the adjacent button is invalidated, so that erroneous operation can be prevented.
