Description

  The present invention relates to an apparatus and a method for preventing a terminal device from performing an unintended process due to a user's erroneous operation.

  A terminal device that performs information processing executes various processes in accordance with user operations. For example, in a terminal device having a communication function such as a mobile phone, a user can edit or send an e-mail by operating the terminal device.

  However, if the user makes a mistake, the terminal device may execute a process unintended by the user. Especially in small terminal devices such as mobile phones, the number of key buttons that can be placed is limited, so buttons can be placed on the side of the case that can be touched by the hand, or a touch panel can be placed on the screen to display buttons. Software keys that display meaning are arranged on the top so that complicated functions can be used with few operations. As its detriment, there are cases where, for example, buttons having different functions for each screen at the button positions on the same touch panel, for example, mail reply and transmission must be arranged. As a habitual action of human beings, double-clicking a place where one touch is good or making a wrong input and processing decision on the screen that continues due to an erroneous operation with screen transition during continuous data input. There were times when I was lost. In addition, erroneous operations have occurred due to delays in feedback from the system with respect to input and delays in updating the display.

  The same applies to software keys. In the case of a touch panel, unlike a physical button, there is no uneven shape and no sinking (stroke) at the time of button operation, so that an erroneous operation such as touching an adjacent key accidentally has occurred.

  Hereinafter, some specific examples will be described.

  When replying to an e-mail received by a mobile phone, or when creating a new e-mail and sending it, the send operation is performed with no data in the body of the e-mail. An email was sometimes sent.

  In general, in a state where a received mail display screen is displayed, a mobile phone is assigned a “reply” function to a software key so that a reply to the displayed received mail can be easily performed. In this case, when the user presses the “Reply” software key, the mobile phone shifts to a state in which the reply mail edit screen is displayed. When the reply mail editing screen is displayed, the “send” function may be assigned to the same software key. When the user presses the “Send” software key after editing the reply mail, the mobile phone transmits the reply mail.

  However, in a mobile phone having such a configuration, when the received mail display screen is displayed and the software key assigned with “Reply” is accidentally pressed twice in succession, the mobile phone is immediately followed by “Reply”. "Transmission" is instructed. In that case, the reply mail is sent without any editing.

  In addition to the case where the user unconsciously presses the software key twice, the user presses the same software key again as a result when there is a processing delay of the mobile phone and it is not possible to confirm whether the software key is pressed correctly. May be pressed twice or more consecutively.

  In addition, if the setting for prohibiting the operation confirmation sound of the mobile phone is set, the user cannot check whether the software key is correctly pressed due to the behavior of the mobile phone, and may press the same software key again. is there.

  On the other hand, in order to prevent the terminal device from performing an undesired operation, a terminal device having a function for prompting the user to reconfirm before executing a process for an operation performed by the user has been proposed (Patent Literature). 1).

  The terminal device disclosed in Patent Literature 1 investigates whether or not a restriction word / phrase is included in the title, text, or attached file of the e-mail before sending the e-mail. Prompt the user for reconfirmation. As restricted words, it is assumed that words used in corporate internal secrets and slander are set.

  In general information processing apparatuses, it is widely performed to prompt the user to reconfirm before performing a process having a large influence by a user operation. For example, the user may be prompted to reconfirm before executing the process of deleting data.

  Further, in general information processing apparatuses, it is widely performed to check whether data and text input by a user are formally appropriate and to prompt the user to input again if they are not appropriate. For example, when full-width characters are input as data to be input in half-width characters, the user may be prompted to input again.

JP 2004-227056 A

  The technique described in the above-mentioned Patent Document 1 confirms whether or not a specific word / phrase is included in an e-mail regardless of an erroneous operation. Therefore, it is possible to prevent the internal confidential information of the company from leaking on the network and sending the slandering sentence to the network by setting the specific word / phrase. However, it is not possible to effectively prevent an unintended process from being executed due to an erroneous operation of the user, such as sending an empty mail due to an erroneous operation.

  In addition, since a process unintended by the user due to an erroneous operation is not necessarily a process that has a large influence, even if a method that prompts the user to reconfirm before performing a process that has a large influence, an unintended process by the user's erroneous operation is executed. Cannot be effectively prevented.

  In addition, even if there is an erroneous operation, the input characters may be formally appropriate, so even if the data or text is confirmed formally, an unintended process is executed due to an erroneous operation by the user. Cannot be effectively prevented.

  The objective of this invention is providing the technique which prevents effectively that a terminal device performs the process which a user does not intend by user's misoperation.

In order to achieve the above object, the erroneous operation preventing device of the present invention is
An input means for accepting an operation by the user;
An error operation pattern, which is an operation pattern that can occur due to an error of the user, is defined in advance, and when the requested operation received by the input means corresponds to the error operation pattern, the user is prompted for confirmation and is confirmed by the input means. Control means for executing processing corresponding to the requested operation after the operation is accepted.

The erroneous operation prevention method of the present invention is an erroneous operation prevention method in a terminal device that operates according to a user's operation,
Information of an erroneous operation pattern that is a pattern of an operation that can occur due to an error of the user is defined in advance,
If the requested operation accepted by the terminal device corresponds to the erroneous operation pattern, prompt the user for confirmation,
After the confirmation operation is accepted by the terminal device, a process corresponding to the requested operation is executed.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent effectively that a terminal device performs the process which a user does not intend by user's misoperation.

  Embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  First, a schematic embodiment of the present invention will be described.

  FIG. 1 is a block diagram illustrating a configuration of an erroneous operation preventing apparatus according to the present embodiment. The erroneous operation prevention device 11 is a device that is incorporated in the terminal device 10 such as a mobile phone and prevents a process unintended by the user from being executed due to an erroneous operation on the terminal device 10.

  The erroneous operation prevention device 11 has an input unit 12 and a control unit 13.

  The input unit 12 is an operation unit that accepts an operation by a user, or an interface that notifies an input from an input device connected from the outside of the terminal device 10. For example, a key operation unit using a hardware key or a software key, a touch pad A touch panel integrated with a display.

  The control unit 13 performs control for preventing the terminal device 10 from executing processing unintended by the user due to an erroneous operation. Specifically, the control unit 13 holds in advance information on an erroneous operation pattern, which is an operation pattern that may occur due to a user error, and if the requested operation received by the input unit 12 corresponds to an erroneous operation pattern, the control unit 13 Confirmation is further urged, and after the confirmation operation is accepted by the input unit 12, processing corresponding to the requested operation is executed.

  The confirmation of the user is, for example, a method of displaying a processing content and a sentence requesting confirmation of whether or not to execute it and a confirmation operation method performed at the time of confirmation on the screen, and processing when the user performs the confirmation operation. Can be considered.

  According to the present embodiment, information on an erroneous operation pattern, which is an operation pattern that may occur due to a user's error, is specified in advance, and the user is prompted to confirm if the requested operation corresponds to the erroneous operation pattern. Can be effectively prevented from executing processing unintended by the user.

  A typical example of the request operation corresponding to the erroneous operation pattern here is an operation of sending an e-mail. The mobile phone is devised to improve operability when sending electronic mail. For example, in a state where a screen for displaying an e-mail or a screen for editing is displayed, an operation that is likely to be performed next is assigned to the software key. Therefore, the operation speed increases as the user becomes proficient in the operation of electronic mail. However, the possibility of erroneous operation increases accordingly. If an e-mail not intended by the user is transmitted due to an erroneous operation, it is difficult to correct it later. In this embodiment, it is possible to effectively prevent an electronic mail not intended by the user from being transmitted due to an erroneous operation.

  Specific examples of erroneous operation patterns include an operation pattern that requests transmission of an email that does not contain data in the body, an operation pattern that requires transmission of an email that the user has not edited, and the user edited the body. Send an e-mail whose editing is forcibly terminated due to an event, an operation pattern that requires sending an e-mail to an address registered in the address book, or an address that has been sent or received in the past An operation pattern or the like that requires

  These are operation patterns that are likely to be emails sent by mistakes, so prompting the user for confirmation when they occur effectively prevents emails not intended by the user from being sent by mistakes. Can be prevented.

  In the above description, transmission of an electronic mail by a mobile phone has been described. However, the present invention is not limited thereto, and can be widely applied to general processing of a terminal device. For example, the present invention can also be applied when preventing erroneous information from being registered in the portable information terminal due to a user's erroneous operation.

  Further, the input unit may be a variable input unit capable of switching processing corresponding to the same operation. Examples of the variable input unit include a software key, a touch pad, and a touch panel.

  When the input unit is a variable input unit such as a software key, the erroneous operation prevention device 11 registers in advance as an erroneous operation pattern an erroneous operation pattern that occurs when the assignment of processing corresponding to the same operation is switched. It is valid.

  For example, it is only necessary to register an erroneous operation pattern that occurs when the assignment of the function to the software key capable of switching the assigned function is switched as an erroneous operation pattern.

  Then, an operation pattern for requesting transmission of an e-mail by the software key may be set as an erroneous operation pattern without passing through another operation after the function for transmitting the e-mail is assigned to the software key.

  Alternatively, an operation pattern for requesting transmission of an e-mail by the software key within a predetermined time after the function for transmitting the e-mail is assigned to the software key may be set as an erroneous operation pattern. For example, the predetermined time may be set to a time that is assumed to be that the user presses the software key without recognizing that the transmission of the electronic mail is assigned to the software key.

  In addition, the input unit is a touch panel that is configured integrally with a display that displays an image and receives a touch operation by a user. A function assigned to a touch operation on a predetermined position of the touch panel is a function of displaying a predetermined position on the display. The present invention is also effective when switching with switching. In that case, a pattern of an erroneous operation that occurs when the assignment of a function to a touch operation at a predetermined position is switched may be registered as an erroneous operation pattern.

  For example, an operation pattern for requesting transmission of an e-mail by a touch operation after a function for transmitting an e-mail is assigned to a touch operation at a predetermined position without using another operation may be set as an erroneous operation pattern.

  Alternatively, an operation pattern that requests transmission of an e-mail by the touch operation within a predetermined time after the function of transmitting the e-mail is assigned to the touch operation at a predetermined position may be set as an erroneous operation pattern.

  Hereinafter, more specific examples of the present embodiment will be described.

(First embodiment)
FIG. 2 is a block diagram showing the configuration of the mobile phone according to the present embodiment. Referring to FIG. 1, the mobile phone includes a control unit 1-1, an antenna 1-2, a radio unit 1-3, an operation unit 1-4, a display unit 1-5, and a memory unit 1-6.

  The control unit 1-1 has a CPU (Central Processing Unit) 1-1-1, and controls each connected block based on the control program 1-1-2.

  The radio unit 1-3 transmits and receives control signals and user data signals to and from a base station (not shown) of the mobile communication system via the antenna 1-2. The radio unit 1-3 modulates the transmission signal from the control unit 1-1 and transmits it to the base station. The radio unit 1-3 demodulates the signal received from the base station and sends the demodulated signal to the control unit 1-1. The received signal is analyzed by the control unit 1-1.

  If the signal from the radio unit 1-3 is audio data, the control unit 1-1 decodes and outputs it as audio. If the signal is other than audio data, the control unit 1-1 performs processing according to the received data.

  The operation unit 1-4 includes a plurality of keys, and these keys include a character input button, a mail transmission button, a mail reply button, and a mail transfer button for creating an electronic mail.

  The display unit 1-5 uses a device such as a liquid crystal or EL (Electro-Luminescence), and displays various images according to instructions from the control unit 1-1.

  The memory unit 1-6 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and holds various data. The memory unit 1-6 includes an area 1-6-1 for storing received mail, an area 1-6-2 for editing the text of outgoing mail, date and time of transmission / reception of mail, destination, subject, and mail storing the text. Transmission / reception history area 1-6-3, telephone book area 1-6-4 for storing data such as telephone number, mail address, name, etc., temporary storage area for cell phone status and data editing 1-6-5 Is configured.

  3 to 5 are flowcharts showing the flow of processing when there is a key input in a state where the mail function is activated. FIG. 6 is a flowchart showing a processing flow when a key operation for browsing received mail is performed in a state where the mail function is activated. From this state, mail reply or forwarding is activated. FIG. 7 is a flowchart showing a flow of processing to be executed in accordance with the determination result by determining whether or not to end the mail editing state in a state where the mail function is activated. FIG. 8 is a flowchart showing a flow of processing to be executed in accordance with the determination result by determining whether or not the data of the e-mail to be transmitted can be transmitted without editing in the state where the mail function is activated. It is.

  Referring to FIG. 3, the control unit 1-1 analyzes the key data of the key pressed by the operation unit 1-4 (step 101). Next, the control unit 1-1 determines whether or not the current state of the mobile phone is creating a mail (step 102).

  When the mail is being created, the control unit 1-1 determines whether or not the key data of the pressed key is a key for requesting mail transmission (step 103). If the key is a key for requesting mail transmission, the control unit 1-1 determines whether or not there is data of the transmitted mail in the transmitted mail text editing area 1-6-2 (step 104).

  When there is outgoing mail data in the outgoing mail body editing area 1-6-2, the control unit 1-1 determines whether or not the currently created outgoing mail is edited with reference to the incoming mail data. (Step 105). When the outgoing mail being edited is a reference to the data of the incoming mail, the control unit 1-1 adds data other than the quoted data from the incoming mail to the outgoing mail data in the outgoing mail text editing area 1-6-2. It is determined whether or not data is included (step 106).

  When the outgoing mail being edited includes data other than the quoted data, or when the outgoing mail being edited is not a quotation of the received mail, the control unit 1-1 sends the outgoing mail text editing area 1-6. 2 is transmitted via the wireless unit 1-3 and the antenna 1-2 (step 107).

  When there is no data other than the quoted data in the outgoing mail text editing area 1-6-2 or when there is no data in the outgoing mail text, the control unit 1-1 sends the mail without writing the text. It is determined that transmission is to be performed, and an empty mail transmission confirmation screen is displayed on the display unit 1-5 (step 108). Thereafter, the control unit 1-1 shifts to an empty mail transmission confirmation process (see FIG. 8) and waits for the determination result of whether transmission is possible.

  If it is determined in step 103 that a key that is not a key for requesting mail transmission is pressed, the control unit 1-1 determines whether the key is a key for requesting the end of mail editing. (Step 201 in FIG. 4).

  If the key operation is to request the end of the mail editing, the control unit 1-1 displays a screen for allowing the user to confirm whether the mail editing can be ended (step 202). Thereafter, the control unit 1-1 shifts to a mail editing end confirmation process (see FIG. 7), and waits for a user to input a determination as to whether or not to end editing.

  If the key operation is not a key operation for requesting the end of mail editing, the control unit 1-1 determines whether or not the key operation is to input character data (step 203). If the key operation is to input character data, the control unit 1-1 stores the character data in the outgoing mail body text editing area 1-6-2 (step 204). If the key operation is other than character data input, the control unit 1-1 ends the process and waits for the next input from the operation unit 1-4.

  If it is determined in step 102 in FIG. 3 that the key operation is in a state where mail is not being created, the control unit 1-1 determines whether or not the input key data is a key operation requesting creation of a new mail. Judgment is made (step 301). When the key operation is to request creation of a new mail, the control unit 1-1 displays a mail creation screen for creating a transmission mail on the display unit 1-5, and shifts to a mail creation state (step 302). ). On the other hand, when the key operation is not a request for creating a new mail, the control unit 1-1 determines whether or not the key operation is a request for browsing the received mail (step 303).

  When the key operation is a request for browsing the received mail, the control unit 1-1 displays the received mail stored in the received mail data storage area 1-6-1 (step 304). Thereafter, the control unit 1-1 shifts to a received mail browsing process (see FIG. 6) and waits for the user to select received mail browsing, mail reply, or mail transfer. In step 303, when the key operation is not a request for browsing the received mail, the control unit 1-1 performs a process according to the input key data.

  Next, the operation in the received mail browsing state will be described with reference to FIG.

  The control unit 1-1 analyzes the key data from the operation unit 1-4 (step 401). Then, the control unit 1-1 determines whether or not the input key data indicates a key operation for requesting a mail reply or transfer (step 402). The reply or transfer request here requests a transition to a screen for creating a reply mail to the received mail or a mail for forwarding the received mail. If the key operation indicates a mail reply or transfer request, the control unit 1-1 determines whether or not the user quotes the received mail (step 403).

  When quoting the received mail, the control unit 1-1 stores the received mail data to be quoted in the transmitted mail text editing area 1-6-2 (step 404). After storing the received mail data in the transmitted mail text editing area 1-6-2, the control unit 1-1 displays a mail creation screen together with the data stored in the transmitted mail text editing area 1-6-2. 1-5, and transition to the mail creation state (step 405).

  When the received mail is not quoted, the control unit 1-1 displays an empty mail creation screen on the display unit 1-5 (step 406). Thereafter, the control unit 1-1 shifts to a process (mail function process (see FIG. 3)) in which the mail function is activated and enters a mail creation state.

  If it is determined in step 402 that the key operation is not a key operation for requesting a reply or transfer of mail, the control unit 1-1 determines whether or not the key operation is a key operation for requesting completion of browsing of the received mail (step 407). If the key operation is to request the end of browsing the received mail, the control unit 1-1 ends the received mail browsing state. If it is not a key operation for requesting the end of browsing the received mail, the control unit 1-1 continues the received mail browsing state.

  Next, the operation in the mail editing end state will be described with reference to FIG.

  The control unit 1-1 analyzes the key data from the operation unit 1-4 (step 501). It is determined whether or not the input key data is a key operation for requesting the end of mail editing (step 502). If the key operation is a key operation requesting the end of mail editing, the control unit 1-1 initializes the data in the outgoing mail body text editing area 1-6-2 (step 503), and the display unit 1-5 displays before mail editing. Is displayed and the mail editing state is terminated (step 504).

  If it is determined in step 502 that the key operation is to cancel the mail editing end request, the control unit 1-1 displays a mail editing screen on the display unit 1-5 (step 505). Thereafter, the control unit 1-1 shifts to a mail function process (see FIG. 3) and enters a mail creation state.

  Next, with reference to FIG. 8, the operation in the state of confirming whether or not to send a blank mail will be described.

  First, the control unit 1-1 analyzes key data from the operation unit 1-4 (step 601). Subsequently, the control unit 1-1 determines whether or not the input key data is a key operation that requests transmission of a blank mail (step 602). In the case of a key operation for requesting (confirming) transmission of an empty mail, the control unit 1-1 creates a transmission mail with the data in the transmission mail text editing area 1-6-2, and transmits the wireless unit 1-3 and the antenna. It transmits via 1-2 (step 603). Thereafter, the control unit 1-1 displays a screen before mail editing on the display unit 1-5 (step 604).

  If it is determined in step 602 that the input key data is a key operation for canceling the transmission of the empty mail, the control unit 1-1 cancels the transmission of the empty mail and displays the mail editing screen. 5 (step 605). Thereafter, the process shifts to a mail function process (see FIG. 3) and enters a mail creation state.

  As described above, according to the present embodiment, when there is no data in the mail body, such as when replying to mail or creating a new mail, or when replying by quoting the mail body or forwarding the mail, It is possible to prevent the user from making a mistake in key operation and sending an empty mail by mistake when there is no edited data in the body of the mail.

(Second embodiment)
In the first embodiment, if there is no data in the body of the e-mail when the e-mail is transmitted, the control unit 1-1 confirms with the user whether an empty mail can be transmitted unconditionally. However, the present invention is not limited to this. A blank e-mail may be transmitted from a mobile phone to a company for membership registration on a website provided by the company. The empty mail in that case is not caused by an erroneous operation. Therefore, in the second embodiment, at the time of transmitting a normal empty mail associated with member registration or the like, the empty mail can be transmitted without confirming with the user whether or not the empty mail may be transmitted.

  FIG. 9 is a flowchart showing the flow of processing when there is a key input in a state where the mail function is activated in the second embodiment. In the second embodiment, the process of the flowchart of FIG. 9 is performed instead of the flowchart of FIG. 3 of the first embodiment.

  Referring to FIG. 9, after performing the processing of steps 101 to 106 as in FIG. 3, the control unit 1-1 sends data other than the quoted data (edited data) to the outgoing mail body text editing area 1-6-2. If there is no (data), it is checked whether or not the destination mail address of the outgoing mail being edited is registered in the telephone directory storage area 1-6-4 (step 707).

  When the transmission destination mail address is not stored in the telephone directory storage area 1-6-4, the control unit 1-1 determines whether the transmission destination is an address that has transmitted or received an e-mail in the past. This is confirmed by searching the mail transmission / reception history area 1-6-3 (step 708). When there is a destination mail address in the phone book storage area 1-6-4 or the transmission / reception history area 1-6-3, the control unit 1-1 displays a blank mail transmission confirmation screen on the display unit 1-5. (Step 709). Thereafter, the control unit 1-1 shifts to the empty mail transmission confirmation process (FIG. 8) and waits for the user to input a determination as to whether or not to send an e-mail.

  If neither the telephone directory storage area 1-6-4 nor the transmission / reception history area 1-6-3 has a destination mail address, the control unit 1-1 transmits a mail to the destination mail address for the first time. For example, it is determined that the user intentionally transmits a blank mail, and the blank mail is transmitted via the radio unit 1-3 and the antenna 1-2 without user confirmation (step 710).

  According to the present embodiment, when it is assumed that the user intends to send a blank mail intentionally, the control unit 1-1 transmits the blank mail without allowing the user to confirm, so the user's useless confirmation. Work can be reduced.

(Third embodiment)
In the first and second embodiments, when an empty e-mail or an e-mail that has not been edited by quoting a received e-mail is about to be sent, the user is asked whether or not the e-mail can be sent. there were. However, the present invention is not limited to this.

  In the third embodiment, whether or not the e-mail can be transmitted even when the e-mail editing is forcibly terminated due to the occurrence of an event and the editing of the e-mail is not completed normally. Is to be confirmed by the user.

  FIG. 10 is a block diagram showing the configuration of the terminal device according to the third embodiment. Referring to FIG. 10, the terminal device includes an antenna 1-2, a radio unit 1-3, an operation unit 1-4, a display unit 1-5, and a control unit 2-1.

  The operation unit 1-4 receives user operations and instructions. Here, the operation unit 1-4 includes a software key whose function assignment is appropriately changed and a touch panel integrated with the display.

  The display unit 104 is a display that displays a screen under the control of the control unit 2-1, and displays information input from the operation unit 1-4 and a processing result by the control unit 2-1.

  The wireless unit 1-3 is a circuit that enables wireless communication by the terminal device, and the control unit 2-1 uses the wireless unit 1-3 when performing wireless communication.

  The control unit 2-1 includes a CPU, a RAM, a ROM, and a timer in hardware as in a general computer system, and controls each block by executing a control program. Functionally, when the control unit 2-1 executes the control program, a state transition management unit 2-1-1, an editing state management unit 2-1-2, and a processing unit 2-1-3 are formed. The

  The editing state management unit 2-1-2 stores a processing state (editing state) related to text editing by the user. Examples of the editing state include a state in which editing by the user is possible (editable state), a state in which text editing by the user has started (editing start state), and a process in accordance with the edited text after successful editing. There is a state that can be executed (edit completed state). The editing state stored in the editing state management unit 2-1-2 can be read and written from the processing unit 2-1-3.

  The state transition management unit 2-1-1 defines an input signal by a user operation received from the operation unit 1-4 as key matrix ON / OFF information or touch panel ON / OFF coordinates of the operation unit 1-4. The data is converted into input data or a command and output to the processing unit 2-1-3.

  The state transition management unit 2-1-1 holds predefined screen information, manages the state of the device, and receives a screen display command from the processing unit 2-1-3. A screen corresponding to the command is displayed on the display unit 104. In addition, the state transition management unit 2-1-1 receives definitions relating to input data, commands, and screen information from the processing unit 2-1-3 as appropriate, and executes various processes such as state transitions based on the received information.

  Furthermore, the state transition management unit 2-1-1 updates the editing state stored in the editing state management unit 2-1-2 as appropriate. When there is an input from the operation unit 1-4, the state transition management unit 2-2-1 transitions the state of the editing state management unit 2-1-2 in accordance with the input as determined in advance.

  Further, when the state transition management unit 2-1-1 receives a screen display command from the processing unit 2-1-3 and causes the display unit 104 to display a screen corresponding to the command, the editing state management unit 2- The editing state stored in 1-2 is appropriately changed.

  The processing unit 2-1-3 is called at the time of character editing operation, and immediately after that, the editing state stored in the editing state management unit 2-1-2 is set to the editing start state, and after the editing operation is completed. Set the edit state to the edit completed state.

  In addition, the processing unit 2-1-3 edited the editing state stored in the editing state management unit 2-1-2 when the editing state is not the editing completion state, that is, when the editing has not been completed normally. If there is an instruction to start processing relating to text, the user is confirmed through the display on the display unit 104 whether or not the instructed processing can be started.

  Next, the operation of the terminal device of this embodiment will be described.

  FIG. 11 is a diagram illustrating an example of a display screen in the process of browsing the received mail on the terminal device, editing the transmitted mail, and transmitting it. 12 to 14 are flowcharts showing the operation of the terminal device according to the third embodiment.

  FIG. 11A shows an example of a display screen when the user browses the received mail. A “reply” function is assigned to one of the software keys. When the user presses the “Reply” software key in the state of FIG. 11A, the user can edit the outgoing mail that quotes the received mail. FIG. 11B shows a display screen in a state where the user can edit the outgoing mail. A “send” function is assigned to the software key. In the state shown in FIG. 11B, when the user presses the “send” software key, the terminal device sends an outgoing mail. FIG. 11C shows a display screen during mail transmission.

  The operations shown in FIGS. 12, 13, and 14 will be described by taking the process shown in FIG. 11 as an example.

  Here, it is assumed that the operation starts from the state where the received mail is displayed as shown in FIG. The processing unit 2-1-3 notifies the state transition management unit 2-1-1 of the screen to be displayed and the definition information of the operation content for the key buttons and touch panel coordinates on the screen, and the display unit 1-5 The instructed display screen is displayed.

  Referring to FIG. 12, when the operation unit 1-4 receives an operation by the user such as viewing, replying, or deleting the content of the received mail (step 801), the operation information is transferred from the operation unit 1-4 to the state transition management unit. 2-1-1 is notified (step 802). Here, as an example, it is assumed that the user presses the right (left from the terminal device) software key “Reply”.

  The state transition management unit 2-1-1 converts the operation information into a command or data indicating the operation content, and notifies the processing unit 2-1-3. The processing unit 2-1-3 determines an editing state to be transferred next based on the command, and determines whether or not the next editing state is an editable state (step 803). Here, since the software key “Reply” has been pressed, the processing unit 2-1-3 displays a screen for editing outgoing mail on the display unit 1-5 via the state transition management unit 2-1-1. At the same time, it notifies the editable state management section 2-1-2 of the editable state.

  Referring to FIG. 13, the editing state management unit 2-1-2 receives a notification indicating that the editing is possible, and stores the state (step 901). Subsequently, when the user corrects the text of the outgoing mail (YES in step 902), the processing unit 2-1-3 shifts the editing state of the editing state management unit 2-1-2 to the editing start state (step 903). .

  When the text is edited by the processing unit 2-1-3 (step 904-905) and the text editing is normally completed, the processing unit 2-1-3 is in an editing completion state in the editing status management 2-1-2. Remember.

  Further, when the user does not subsequently edit the text of the outgoing mail in the determination of step 902, or when it is decided not to send the mail in the confirmation of whether or not the user can send the mail in step 1002 described later (in FIG. 13). E) proceeds to step 907.

  Here, the user may request to start processing related to the edited text, or may resume editing. When editing is resumed, the process returns to step 902 (NO in step 907).

  Here, it is assumed that the user presses the right software switch “Send” from the state where the screen of FIG. 11B is displayed. Since this software switch “transmission” requests the start of the process of transmitting an e-mail, the processing unit 2-1-3 starts the process (YES in Step 907).

  Referring to FIG. 14, upon receiving an instruction to start mail transmission processing, the editing state management unit 2-1-2 determines whether or not the stored editing state is an editing completion state (step 1001). If it is not in the editing completion state (No in Step 1001), the editing state management unit 2-1-2 notifies the processing unit 2-1-3 to that effect. The processing unit 2-1-3 receives the notification and confirms with the user whether or not the mail can be transmitted via the display on the display unit 1-5.

  When the mail transmission process is not performed, the process proceeds to step 907 in FIG. 13 and the screen in FIG. 11B is displayed again. If the mail transmission process may be executed (YES in step 1002), or if the editing is completed in the determination in step 1001, the processing unit 2-1-3 mail transmission process is executed (step 1003). Thereafter, the processing unit 2-1-3 displays the screen during transmission in FIG. 11C on the display unit 1-5 and further displays a transmission completion screen when the transmission is completed, and the editing state management unit 2-2. Clear the editing status of 1-2.

  According to the present embodiment, it is possible to prevent an email that has not been edited by the user from being erroneously transmitted, and prevent an email that has been forcibly terminated due to an event from being erroneously transmitted. Can do.

  As shown in FIG. 10, in this embodiment, the processing unit 2-1-3, the state transition management unit 2-1-1, and the editing state management unit 2-1-2 are separately provided for each function. Although the control unit 2-1 that executes the control program by the CPU is arranged, the overall functions of the processing unit 2-1-3, the state transition management unit 2-1-1, and the editing state management unit 2-1-2 Processing may be executed.

  Moreover, although the example in which the editing state management unit 2-1-2 holds one editing state is shown, there are a plurality of input items on one screen, and the editing state is managed for each item. May be. In this case, for example, the editing completion state is set to “1”, the other states are set to “0”, and the user determines whether the processing can be started when the logical product of the states of all items does not become “1”. You should confirm with.

In the third embodiment, an erroneous operation on the software key is illustrated, but the present invention is not limited to this. As another example, the same configuration and operation as in this embodiment can be applied to an erroneous operation on a touch panel integrated with a display.
(Fourth embodiment)
In the third embodiment, whether or not to prompt the user for confirmation at the start of processing is selected according to whether or not the editing completion state has been reached after the editing start state, but the present invention is limited to this. It is not a thing. In the fourth embodiment, when a command is input, the time interval between the previous command and the current command is measured, and if the time interval is short, it is determined that there is a possibility that the command is due to an erroneous operation, and processing is performed by the user. Check if you can start.

  FIG. 15 is a block diagram showing a configuration of a terminal device according to the fourth embodiment. Referring to FIG. 15, the terminal device of the fourth embodiment is different from the terminal device of the third embodiment shown in FIG. 10 in the functional configuration and operation of the control unit 3-1.

  The control unit 3-1 includes a state transition management unit 3-1-1, a time measuring unit 3-1-2, and a processing unit 3-1-3.

  The state transition management unit 3-1-1 defines an input signal by a user operation received from the operation unit 1-4 as key matrix ON / OFF information or touch panel ON / OFF coordinates of the operation unit 1-4. The data is converted into input data or an instruction and output to the processing unit 3-1-3. The state transition management unit 3-1-1 holds screen information defined in advance, and displays a screen corresponding to the command on the display unit 104 when receiving a command from the processing unit 3-1-3. . The state transition management unit 3-1-1 appropriately receives definitions related to input data, instructions, and screen information from the processing unit 3-1-3, and executes various processes based on the received information.

  Furthermore, the state transition management unit 3-1-1 has various editing states defined in advance. When there is an input from the operation unit 1-4, the state transition management unit 3-1 causes the editing state to transition according to the definition, and the time when the editing state transitions It is recorded in the timer unit 3-1-2. For example, the time measuring unit 3-1-2 is the time when the text editing is completed and the processing start instruction is awaited (processing instruction waiting state), and the processing start instruction is received (processing start) Record the time when the status is reached.

  When the processing unit 3-1-3 receives a processing disclosure instruction in response to an instruction from the state transition management unit 3-1-1, the processing unit 3-1-3 receives the time when the processing is in a waiting state and the processing start instruction. If the time interval is less than or equal to a predetermined time, the user confirms whether or not the process can be started through the display on the display unit 1-5. To do. The predetermined time used here may be set to an arbitrary time as a time for distinguishing whether the instruction is input consciously by the user or the instruction input continuously from the previous input.

  Next, the operation of the terminal device according to this embodiment will be described.

  FIG. 16 is a diagram illustrating an example of a display screen from when a user erroneously operates on a PIN (Personal identification number) input screen to make an emergency call. Here, the user tries to input the telephone number “71100” on the PIN input screen, and erroneously presses “emergency call” instead of “7”, and erroneously “telephone” instead of “0” for the second time. It has been pushed.

  17 to 19 are flowcharts showing the operation of the terminal device according to the fourth embodiment. The operations of FIGS. 17, 18 and 19 will be described by taking the process of FIG. 16 as an example.

  Immediately after turning on the power of the terminal device or when the operation is started from a state where the security lock is applied, the terminal device starts an operation in a state of requesting a PIN input. In displaying the screen, the definition information of the operation content corresponding to the screen displayed on the display unit 1-5 from the processing unit 3-1-3 to the state transition management 3-1-1 and the key buttons and touch panel coordinates on the screen. And the instructed display screen is displayed on the display unit 1-5.

  Referring to FIG. 17, the processing unit 3-1-3 displays the screen of FIG. 16A on the display unit 1-5 via the state transition management unit 3-1-1 and requests the user to enter a PIN. (Step 1101), the presence or absence of input is monitored (Step 1102). When the user inputs information, the input information is notified from the operation unit 1-4 to the state transition management unit 3-1-1. The input information is converted into a command by the state transition management unit 3-1-1 and notified to the processing unit 3-1-3.

  Here, the user intends to input “71100”, and instead of “7”, the user touches the “emergency call” touch button arranged immediately below. Since the “emergency call” touch button has been touched, the processing unit 3-1-3 causes the display unit 1-5 to display the screen illustrated in FIG. 16B via the state transition management unit 3-1-1. The system waits for the input of an emergency telephone number and a call instruction. Therefore, the editing state managed by the state transition management unit 3-1-1 is in a processing instruction waiting state (YES in step 1103).

  Referring to FIG. 18, since the touch panel button “emergency call” is touched, the operation information is converted into a command by the state transition management unit 3-1-1 and notified to the processing unit 3-1-3. Moreover, since the state transition management unit 3-1-1 sets the editing state to the process instruction waiting state, the time transition unit 3-1-2 records the time (first time) at that time.

  Subsequently, the user inputs “110”. Since the input is a telephone number, the processing unit 3-1-3 completes the input character by character (steps 1203-1204). When “110” is input, in this embodiment, if three digits are input, it is considered that the editing has been completed, the editing is completed (YES in step 1205), and the display screen displays “0” until then. The “phone” touch button is displayed at the position where the “touch button” was displayed. The “telephone” touch button is a button for instructing an outgoing call. In this state, the user accidentally touches the “telephone” touch button instead of “0”.

  Since the touch on the touch button “telephone” is an instruction to start processing, the state transition management unit 3-1-1 determines that the processing start is requested (step 1205), and the time at which the processing start instruction is performed (first time) (Second time) is recorded in the time measuring unit 3-1-2 (step 1206).

  Referring to FIG. 19, next, the processing unit 3-1-3 determines whether or not the time difference between the first time and the second time is greater than a predetermined time (step 1301). If the time difference between the first time and the second time is equal to or less than the predetermined time, the processing unit 3-1-3 determines that there is a possibility that the instruction is erroneously input by the user, and is about to start. The contents of the process are displayed on the display unit 1-5, and whether or not the process can be started is confirmed with the user (step 1302). When the user inputs that the process is not started, the processing unit 3-1-3 proceeds to the process of step 1201 (NO in step 1302).

  When the user inputs to start processing (NO in step 1302), or when the time difference between the first time and the second time exceeds a predetermined time in the determination in step 1301 (in step 1301) YES), the processing unit 3-1-3 executes processing without confirming with the user (step 1303). The processing unit 3-1-3 starts processing and clears the second time recorded in the time measuring unit 3-1-2.

  As described above, according to the present embodiment, it is possible to prevent a process unintended by the user from being executed when the user performs an erroneous operation excessively by PIN input or menu operation.

  As shown in FIG. 15, in this embodiment, the processing unit 3-1-3, the state transition management unit 3-1-1, and the time measuring unit 3-1-2 are separately arranged for each function. However, the control unit 3-1 in which the CPU executes the control program executes processing of the entire functions of the processing unit 3-1-3, the state transition management unit 3-1-1, and the time measuring unit 3-1-2. It may be a thing. Further, an internal timer may be used for the control unit 3-1 to perform the function of the time measuring unit 3-1-2.

  Moreover, although the example which time-measurement part 3-1-2 measures one pair of time called 1st and 2nd time was shown, several sets of time are measured and the time difference of either set is below predetermined time. If so, the user may confirm whether or not the process can be started. Also, three or more times are measured, and a time difference is calculated by appropriately combining them. If the time difference is equal to or less than a predetermined time, the user is asked whether the process can be started. Good.

  In the present embodiment, only the second time is cleared when the process is executed in the processing flow of recording the second time after recording the first time. However, the present invention is not limited to this. Is not to be done. Depending on the processing content and conditions, both the first and second times may be cleared.

  Further, in this embodiment, when the time from the waiting state for processing instruction to the start of processing state is equal to or shorter than a predetermined time, the user is asked whether the processing can be started. The present invention is not limited to this. As another example, when a process instruction wait state is entered and the process shifts to a process start state without any other operation, the user may be asked whether the process can be started.

  Moreover, although the present embodiment illustrates an erroneous operation on the touch panel, the present invention is not limited to this. As another example, the same configuration and operation as in this embodiment can be applied to an erroneous operation on a software key.
