An operation button erroneous input prevention method, an input device, and a mobile terminal with an erroneous input prevention function according to the present invention will be described below with reference to an embodiment using a mobile phone as an example.
(Description of configuration)
FIG. 1 is a block diagram in which functions of a mobile phone according to an embodiment of the present invention are simplified.
In FIG. 1, 10 is a mobile phone, 101 is a button operation unit (keyboard), 102 is a wireless device, 103 is a display, 104 is a control device, 105 is a memory device, 106 is an audio device, 107 is a microphone, 108 Is a receiver.

  When the user of the mobile phone 10 dials and presses the numeric button of the button operation unit 101 to input the telephone number of the connection destination, the control system device 104 recognizes the input telephone number, and the button operation unit 101 A number corresponding to the number button pressed is displayed on the display 103. Further, when the user presses a start button (call button), the communication control function of the control system device 104 performs a transmission operation via the wireless system device 102 and performs a connection operation with the partner terminal via the base station.

  In addition, the telephone number of the connection destination is stored in the memory device 105 as a call history, a call history, or a speed dial under the control of the control system device 104, and can be sent again with a simple operation.

  FIG. 2 is a diagram showing a front view of the mobile phone, and FIG. 3 is a diagram showing a side view thereof. In addition to the numeric buttons shown in FIG. 2, the button operation unit 101 has function buttons such as a menu button and a start button for outgoing calls arranged on the front surface of the casing. Further, a side button a 1011 and a side button b 1012 on the side surface of the housing shown in FIG. 3 are also part of the button operation unit 101.

  The erroneous input prevention function for button input according to this embodiment can be turned on / off in advance by a button operation. That is, it is possible to select and set whether or not to set the button operation to be invalidated (button invalid setting) according to the situation of handling the mobile phone, and the setting is stored in the memory device 105.

  The control system device 104 detects a signal output from the button operation unit 101 when a button operation is performed, determines which button is pressed, and sets the above-described erroneous input prevention function stored in the memory device 105. Enables or disables button operation input according to the status.

  When the button operation is enabled, the button operation input is processed as usual and displayed on the display 103 as the button is operated. When the button is disabled, the erroneous input prevention function is activated, and the button operation is a normal button operation. Although the button input is treated as invalid in the single press operation, the button operation is valid only during the button operation in which the button invalid setting is canceled while a specific button of the button operation unit 101 is being pressed.

  This control is performed by the control system device 104. In the state of the button invalid setting, for example, storage control of the state of the button pressed at the present time is performed, and in the pressing operation state of any one button, other buttons (inputs are input). When the desired button is pressed, the input by pressing the other button is validated and the input data of the button is output.

  Therefore, a flag storage area for storing a flag corresponding to a specific button of the button operation unit 101 is secured in the memory device 105, and the control system device 104 corresponds to the storage area corresponding to the pressing / release operation of the specific button. Each flag is stored or erased, thereby controlling the display of the pressed state of the specific button, determining whether the flag exists when another button is pressed, and the flag already exists. Only in such a case, control such as outputting input data of other buttons to the display 103 is performed.

FIG. 4 is a diagram showing a processing flow of the control system apparatus according to the first embodiment.
In this embodiment, the memory device 105 is referenced to determine whether the button invalid setting is on or off (s1). If the button invalid setting is off, the button operation is always valid. The mode is set (s6). If the invalid setting is on in step s1, the user waits for a button operation (s2).

  When a button operation is detected (s2), it is determined whether the button operation is a specific button (s3). In the case of a specific button, it is determined whether the operation is pressed or released (s4). If the button is pressed (s4, YES), a flag indicating the pressed state is stored in the flag storage area and the flow returns to the start (s5). When the specific button is released (s4, NO), the already stored flag is deleted and the process returns to the start of the flow (s10).

  If a button operation is detected in step s2 and the button is not a specific button (s3, NO), it is determined whether the operation of this button is pressed or released (s7). If it is pressed (s7, YES), It is determined whether or not a flag exists in the flag storage area (s8). If the flag exists, the operation of the button is validated, data is output to the display 103 or the like, and the process returns to the flow star (s9). If the button operation is released in step s7 (s7, NO) and if no flag is present in step s8 (s8, NO), the process returns to the start of the flow.

As a result of the above processing, a flag exists in the flag storage area only when a specific button is pressed, and when the other button is subsequently pressed, the input operation by pressing the other button is validated and input data is output. Become.
Although it is preferable to use one of the side buttons of the button input unit of the cellular phone as the specific button of the present embodiment, it is not limited to such button assignment, and all of the plurality of side buttons are assigned. The button invalidation setting can be canceled when any of the plurality of buttons is pressed.

  In the present embodiment, if the specific button is pressed, all subsequent button operations are valid, and input by simultaneously pressing a plurality of buttons is allowed.

(Description of operation)
An operation example of the present embodiment will be described below with a typical input operation example of a cellular phone.
When the button (operation) invalidation setting is in an ON state, a flag indicating the state is stored in the memory device 105, and is used for determination of validity / invalidity when the button is pressed. The validity of the pressed button is determined when the button is pressed.

  FIG. 5 is a diagram showing an example of a transmission procedure using the speed dial transmission function during the button invalid setting. More specifically, a button pressing procedure when the user temporarily cancels the button invalidation setting and makes a call with the speed dial transmission function is shown in a time chart format. In this example, an operation is shown in which a “side a” button, a “1” button, and a “start” button are sequentially pressed to make a speed dial call.

  First, the speed dial transmission function will be briefly described. The abbreviated dialing function allows you to register phone numbers in management numbers 0 to 9 in the phone book, so just press one of “0” to “9” and press the “Start” button. This function allows you to make a call quickly.

  The control system device also constitutes a means for temporarily canceling the button invalidation setting. The above-mentioned specific button that gives the button invalidity cancellation condition is a side button a (hereinafter, “side a” button) 1011, The button operation is valid during continuous pressing.

In FIG. 5, at time t11, the “side a” button 1011 is pressed, and thereafter, the other buttons are enabled (waiting for input).
At time t12, pressing of the “1” button is confirmed.
Subsequently, at time t13, the “1” button is released, and acceptance of the button press is started again.
Further, at time t14, pressing of the “start” button is confirmed, and a speed dial transmission operation is performed by “1” + “start”.
Lastly, the “side a” button 1011 is released at time t15, and thereafter, the button press by any contact or the like becomes invalid again.

Next, a description will be given of a procedure in the case where the call operation is not reached because the button is erroneously pressed but the button is invalid.
FIG. 6 is a diagram illustrating an example in which the “side a” button, the “1” button, and the “start” button are pressed in error. Although only the “1” button is enabled, the “start” button is not enabled.

In FIG. 6, at time t21, the “side a” button 1011 is pressed, and the other buttons are enabled.
At time t22, pressing of the “1” button is confirmed.
Subsequently, at time t23, the “1” button is released and acceptance of the button press is started again. However, at time t24, the “side a” button 1011 is opened, and the button operation is invalidated in the opened state.

At time t25, the “start” button is pressed, but the “side a” button is open and thus not effective.
As a result, although the “side a” button, “1” button, and “start” button are pressed, no speed dial transmission is made by mistake.

FIG. 7 is a diagram showing a case where only the “1” button and only the “start” button are pressed in order. A case where neither the “1” button nor the “start” button is enabled is shown.
In FIG. 7, the “1” button is pressed at time t31, but the “side a” button is not pressed, and therefore the “1” button is disabled.
Furthermore, although the “start” button is pressed at time t32, similarly, the “side a” button is not pressed, and thus the “side a” button is disabled.
As a result, although the “1” button and the “start” button are pressed, the speed dial is not erroneously transmitted.

(Embodiment 2)
In the above embodiment, the pressed button is effective when the specific button is pressed and the button is pressed next. It is possible to configure to invalidate the third and subsequent pressed buttons while two or more buttons are pressed.

  FIG. 8 is a diagram showing a process blow that invalidates the third and subsequent pressed buttons. The partial processing (steps s7, s8, s9) of the processing flow shown in FIG. 4 is changed. The configuration and operation of the second embodiment are as follows.

  In the memory device 105 of the second embodiment, a flag storage area for storing a flag corresponding to each button of the button operation unit 101 is secured, and the control system device 104 corresponds to the pressing / release operation for each button. Each flag is stored or deleted in the storage area, and the storage state is controlled so that the pressed state can be referred to, and it is determined which button is pressed and how many flags are stored. Control is performed such that input data of other buttons is output to the display 103 on condition that two flags of a specific button and other buttons exist.

  First, it is determined whether the button invalid setting of the present embodiment is on or off with reference to the memory device 105 (s1). If the button invalid setting is off, the button operation is always valid. (S6). If the invalid setting is on in step s1, the user waits for a button operation (s2).

  When a button operation is detected (s2), it is determined whether the button operation is a specific button (s3). In the case of a specific button, it is determined whether the operation is pressed or released (s4). If the button is pressed (s4, YES), a flag indicating the pressed state is stored in the flag storage area and the flow returns to the start (s5). When the specific button is released (s4, NO), the already stored flag is deleted and the process returns to the start of the flow (s10).

  If a button operation is detected in step s2 and the button is not a specific button (s3, NO), it is determined whether the operation of this button is pressed or released (s7). If it is pressed (s7, YES), The flag of the button is stored in the flag storage area (s11), and whether or not the flag of the specific button exists in the flag storage area is determined (s12). If there is, the number of flags is only two. It is determined whether or not (s13), and when there are only two, the input of the button is validated, data is output, and the flow returns to the start (s14). If the operation of the button is released in step s7, the already stored flag of the button is deleted and the flow returns to the start of the flow (s15). Furthermore, if there is no flag for a specific button in step s12, and if the number of flags is 3 or more in step s13, the process returns to the start of the flow.

  With the above processing, a flag exists in the flag storage area only when a specific button is pressed, and when the other button is subsequently pressed, it is possible to control the input operation by pressing the other button and output the input data. Furthermore, it is possible to perform control such that the third or more button operations following a specific button or the simultaneous operation of two or more buttons excluding the specific button are all invalid.

A specific example of the operation based on the processing flow shown in FIG. 8 will be described below.
FIG. 9 is a diagram illustrating an example in which the button pressed after the third is invalidated. In this example, only the “1” button is valid even when the “side a” button, “1” button, “2” button, and “start” button are pressed.
In FIG. 9, at time t41, the “side a” button 1011 is pressed, and the other buttons are enabled.
At time t42, pressing of the “1” button is confirmed.
Subsequently, at time t43, the “2” button is pressed, but since the “1” button is being pressed, it is recognized as the third pressed button and becomes invalid.
Furthermore, although the “1” button is released at time t44, the “2” button is kept pressed and does not become effective because it does not satisfy the above-described condition of determination at the time of pressing.
Next, the “Start” button is pressed at time t45, but since the “2” button is being pressed, it is recognized as the third pressed button and becomes invalid.
At time t46, the “2” button is released, but the “start” button remains pressed and is not enabled as described above.
At time t47, the “start” button is released and the process waits for the button to be pressed, but at time t48, the “side a” button is released and the state becomes invalid.

Therefore, the “side a” button, “1” button, “2”, and “start” button are pressed and the “1” button is enabled, but the subsequent button presses are disabled and the speed dial is transmitted. It does not lead to.
In the above example, the button invalid setting is temporarily canceled by pressing the “side a” button, but as this button, “side b”, “#”, “*”, “phone book”, etc. It is possible to assign a button not related to the outgoing operation.

  In the above-described embodiment, pressing a specific button (“side a”, “side b”, “#”, “*”, “phone book”) that is not related to the outgoing operation is performed to cancel the invalid button operation. The condition is that the specific button is continuously pressed until another button is input. However, the specific button is not required to be continuously pressed. Embodiment 3 in which any one of the buttons in the range is assigned for canceling the button invalid setting, or any one of the buttons is assigned for canceling the button invalid setting, and the input of the subsequent operation button is validated. It is possible to configure.

  In the third embodiment, a plurality of “number” buttons are used as specific buttons, and cancellation of the button invalidation setting enables subsequent buttons that are sequentially pressed to be the specific buttons or arbitrary buttons. It is. In the third embodiment, an example will be described in which the second and subsequent buttons are invalidated when two or more buttons are pressed.

FIG. 10 is a diagram showing a processing flow of the third embodiment.
For example, the control-system device 104 performs storage control of the state of the button pressed at the present time, and when any one button is pressed, when the other button (button that is desired to be input) is pressed, the other button is pressed. Controls to enable the input by and to output the input data.

  Therefore, the memory device 105 secures a flag storage area for storing a flag corresponding to each button of the button operation unit 101, and the control system device 104 corresponds to the pressing / release operation for each button. Each flag is memorized or deleted, and the pressed state is controlled so that it can be referred to, and the flag storage area is referenced to determine which button is pressed and how many flags are stored. Then, on the condition that there are two flags of an arbitrary button and another button, control is performed such as outputting input data of the button to the display 103 when the other button is pressed.

First, the memory device 105 is referred to determine whether the invalid setting of the present embodiment is in an on state or an off state (s1), and if it is in an off state, the control mode is set to a normal button operation process (s7).
If the invalid setting is on in step s1, the user waits for a button operation. When an operation of an arbitrary button is detected (s2), it is determined whether the button is pressed or released (s3). If the button is pressed, the flag is stored in the flag storage area corresponding to the button of the operation (s4), and the number of flags in the flag area is determined to determine whether the newly stored flag is the second (s5). If it is the second one, the input data corresponding to the button is output to the display 103 or the like and the process returns to the start (s6).

If it is determined in step 3 that the button operation is to release the button, the flag stored when the button is pressed is deleted from the flag area and the process returns to the start (s8).
As a result of the above processing, the state of the button pressed at the present time is stored in the flag storage area, and when any one button is pressed, the input by pressing the other button becomes valid when the other button is pressed. Can be controlled to output the input data.

FIG. 11 shows an example in which the user presses a button “0901234” while canceling invalidation with the “number” button.
In FIG. 11, by pressing the “1” button as an arbitrary button at time t51, the other buttons are enabled (waiting for input).
At time t52, the “0” button is pressed to confirm the input.
At time t53, the “0” button is released and waits for button input again.
At time t54, the “9” button is pressed to confirm the input.
At time t55, the “9” button is released and waits for button input again.
At time t56, the “0” button is pressed to confirm the input.
At time t57, the “1” button is released and the pressed button is switched from “1” to “0”. However, since there is only one pressed button, the input of the button is awaited again.
At time t58, the “1” button is pressed and the input is confirmed.
At time t59, the “1” button is released and waits for button input again.
At time t510, the “2” button is pressed to confirm the input.
At time t511, the “2” button is released and waits for button input again.
At time t512, the “3” button is pressed to confirm the input.
At time t513, the “3” button is released and waits for button input again.
At time t514, the “4” button is pressed to confirm the input.
At time t515, the “4” button is released and waits for button input again.
At time t516, when the “0” button is released, the pressed button disappears, and the button input is invalidated.

As a result, the input by pressing the button is confirmed in the order of “0 901234”.

(Embodiment 4)
Even when an input due to erroneous input prevention according to the present invention is confirmed, it is possible to clear the confirmed input when a predetermined function button is not operated for a certain time after the confirmed input.

  FIG. 12 is a diagram showing a processing flow of the fourth embodiment. It is a figure which shows the processing flow comprised so that it may be cleared automatically after returning to the button invalid setting already input data. After the numerical data is input, the transmission button is not pressed and the button input is invalidated. When a predetermined time has elapsed, the numerical data is automatically cleared by, for example, a timer using a counter (input erasure timer).

  In the fourth embodiment, the processing flow up to step s6 is the same as in FIG. 10, and the number of flags in the post-processing flag storage area in step s6 or s8 is referred to (s17), and the number of flags becomes zero. The input erase timer for T time is started and the time is up (s19). However, if the number of flags is not 0 in s17, the input erasure timer is cleared (count value is reset) and the process returns to the start (s21). If the timer expires (expires) in step s19, the confirmation input is cleared and the process returns to the start (s20).

FIG. 13 is a diagram illustrating an operation example in which input data is cleared by a timer.
In FIG. 13, the button operation from time t61 to t615 is the same as in FIG. 11, but at time t616, when the “0” button is released and the button being pressed disappears and the button input becomes invalid, the input erase timer is started. (S18).
At time t517, there is no continuous button press, the T time input erasure timer expires and stops (s19), and the input that has already been confirmed is cleared.

The transmission operation is normally triggered by pressing the “Start” button, but even if the “Number” button input is confirmed, the input is confirmed if the “Start” button is not confirmed before the timer stops counting. Outgoing dial candidate data is determined to be erroneous input and is erased.
As a result, the buttons are pressed in the order of “10901234”, but the “start” button is not pressed, and the numbers entered with the passage of time from the release of all buttons are cleared, and there is no outgoing dial candidate It becomes.
