JP4830834B2 - Portable mobile communication terminal device and character data creation program - Google Patents

Description

  The present invention relates to a mobile communication terminal device such as a mobile phone having a character input function such as e-mail creation, and more particularly to a storage management technique for character data created by a user.

  When creating a mail in a mobile communication terminal device such as a mobile phone terminal having an electronic mail function, the mail being created may be deleted due to an erroneous operation. The reason for this is that, for general mobile phone terminals, there are many specifications that end the creation of an email by pressing the “End key” and discard the data being created, so the “numeric key” used to enter email characters This is because there is a high possibility that the “end key” that is physically adjacent to the key will be accidentally pressed.

  Unlike a personal computer or the like, a mobile phone terminal has a large number of keys in a small space, and various functions must be assigned to a small number of keys. In particular, the keys to enter numbers and the keys to end functions are often located close to each other, so the functions are accidentally terminated during mail creation and the mail created before the user intended is discarded. There is a problem that it may be done.

  As a means for solving this, it is usually a specification that prompts the user to confirm by displaying a confirmation screen of "Can I quit?" In many cases, the same “numeric key” is pressed continuously when creating an email, so the “End key” may be pressed continuously without looking at the confirmation screen. May be discarded.

  As means for solving such a problem, in Patent Document 1, contents such as mail texts being created by key input are stored as text data in the operation environment storage unit, and an end process is erroneously performed during mail input. When the confirmation message is displayed by pressing the key to execute, the input contents are discarded by selecting and pressing “Yes” or the end process execution key by mistake and the screen returns to the standby screen. In the event of a failure, by pressing the return processing key or the call key on the key operation unit, the contents of the mail text stored in the operation environment storage unit can be reproduced. Even if it is forcibly terminated, a technique is described that makes it possible to call the mail text being created again.

JP 2005-026751 (paragraphs 0004, 0058, 0059)

  According to the invention described in Patent Document 1, it is possible to return the processing content discarded due to interruption by an erroneous operation by the user to the state immediately before the interruption by a single key operation, and the user can re-enter mail, etc. It is possible to increase the efficiency of key input by eliminating the troublesomeness of repeating the same process. However, in the invention described in Patent Document 1, a confirmation message is displayed by pressing a key for executing an end process. Even when the user is intentionally pressing the “Yes” key and exiting when the mail being created is discarded, the data is stored in the operation environment storage unit. .

  Especially when considering security etc., it is extremely inconvenient that unnecessary data being created that is intended to be discarded by such user's intentional termination is left in the storage unit, so There is a problem in that it is necessary to separately provide a means for deleting the backed-up data being created, and an extra operation for deleting the unnecessary data is required.

  In view of the above problems, an object of the present invention is to improve the operability by identifying means for ending a function by a user and providing means for restoring the data only when there is a high possibility of discarding user-created data due to an erroneous operation. And security.

  In the portable mobile communication terminal device having a character input function, the present invention has means for displaying an end confirmation screen on the display unit when detecting the pressing of the “end key” while inputting character data from the key input unit, Means for discarding the input character data and ending the character data input process when the pressing of the “end affirmation key” is detected while the end confirmation screen is displayed; When pressing of the “key” is detected, the input character data is stored in a storage unit and the character data input process is terminated.

  In addition, when a character input start instruction is newly input from the key input unit, means for confirming whether or not the character data is stored in the storage unit, and the character data is stored in the storage unit Means for displaying a restoration confirmation screen for the character data on the display unit, and character data stored in the storage unit when the depression of the “recovery affirmation key” is detected while the restoration confirmation screen is displayed. Means for reading out and displaying on the display unit, resuming the character input process for the displayed character data, and when the depression of the “recovery negative key” is detected during the display of the restoration confirmation screen, It is characterized by having means for discarding existing character data and starting a new character input.

  In addition, the character data creation program of the present invention confirms the end on the display unit when the control unit (computer) of the portable mobile communication terminal device detects that the “end key” is pressed during character data input from the key input unit A process of displaying a screen, a process of discarding the input character data and ending the character data input process when the pressing of the “end affirmation key” is detected while the completion confirmation screen is displayed, and the completion confirmation screen When the pressing of the “end key” is detected again during the display, the inputted character data is stored in a storage unit, and the character data input process is terminated.

  The program also includes a process of confirming whether or not the character data is stored in the storage unit when the character input start instruction is newly input from the key input unit, and the character data is stored in the storage unit. When it is saved, the process for displaying the character data restoration confirmation screen on the display unit, and when the depression of the “recovery affirmative key” is detected during the restoration confirmation screen display, the character data is saved in the storage unit. When the character data is read and displayed on the display unit, the process of resuming the character input process for the displayed character data, and pressing of the “recovery negative key” during the display of the recovery confirmation screen, The stored character data is discarded and a process for starting a new character input is executed.

  The character data creation means and program of the present invention can be applied to an electronic mail creation means or a mail creation program in a portable mobile communication terminal device, and can realize more effective mail creation.

  In the present invention, it is determined whether or not there is a high possibility of the function end due to an erroneous operation by identifying the function end operation by the user, and when it is determined as an erroneous operation, the input character data is stored. When it is judged, the input character data is discarded. Specifically, when the “end key” is pressed during character data input, an end confirmation screen is displayed. When the user presses the “end affirmation key” on the end confirmation screen, the user intentionally ends. If all of the character data entered is judged to have been discarded, and the “end key” is pressed again, it is judged that there is a high possibility of termination of the character data input process due to an erroneous operation, and the user-created data is The input data can be restored by saving without discarding.

  Further, according to the configuration of the present invention, even when the same user operation is ended, it is possible to change whether the data being created is retained or discarded according to the operation procedure, so that the user can select whether to perform data restoration. It can also be used as a means to do this, and there is also an effect that data restoration and disposal in accordance with the user's intention can be realized with a simple operation and configuration.

  According to the present invention, even when it is considered that there is a high possibility that the data being created by the user is discarded due to the termination process due to the user's erroneous operation, the data being created can be easily restored. Therefore, the trouble of creating data again can be saved.

  In addition, if it is highly probable that the data being created has been discarded by the user's intention, it is not necessary to retain unnecessary data by not restoring the data, and information security can be improved. .

  FIG. 1 is a principal block diagram of a mobile phone device showing an embodiment of the present invention. The mobile phone device naturally has a configuration related to the original function of the mobile phone such as wireless communication, but in the figure, only functional blocks related to the present invention are extracted and shown.

  In FIG. 1, the input unit 1 includes a key operation unit including a plurality of dial keys, function keys, cursor keys, and the like corresponding to characters and marks such as numerals, kana, and Roman characters. When operated, the corresponding character data or control data is output.

  The control unit 2 constitutes a CPU that controls various functions of the cellular phone device, but determines information on keys input from the input unit 1 as a function related to the embodiment of the present invention. The screen display content is determined based on the key control unit 21 that performs the function, the function end control unit 22 that controls the end of the function based on the key information determined by the key control unit 21, and the key information determined by the key control unit 21. In addition, a display character control unit 23 that performs screen display via the display unit 4 is provided.

  The storage unit 3 stores various function programs including a mail creation program in order for the CPU to control and operate various functions including the electronic mail function of the mobile phone device. The various data that have been taken in are stored. Further, as a function related to the embodiment of the present invention, a mail storage unit 31 that stores mail (character data) key-input from the input unit 1 is provided. The display unit 4 is configured by an LCD or the like, and is controlled by the display character control unit 23 to display various screens.

  FIG. 2 is a flowchart showing a screen transition image at the time of mail creation according to the present embodiment. Next, details of the operation of this embodiment will be described with reference to FIGS.

  First, step A1 in FIG. 2 shows a mail creation screen by the user, and displays the mail being created on the display unit 4 based on the key input information from the input unit 1. When the “end key” is input from the input unit 1 in this state, the function end control unit 22 displays a confirmation screen “whether to end” via the display character control unit 23 (step A2). If the user performs an operation of selecting “YES” at this time, the normal function is terminated and the mail being created is discarded (step A4).

  When the user performs an operation of selecting “NO” in step A2, the mail creation function is continued by returning to the original mail creation state (step A1) without performing the termination process. On the other hand, when the “end key” is input again from the input unit 1 in step A2, the function end control unit 22 ends the function with the content of the input mail being stored in the mail storage unit 31 (step S2). A3).

  Thereafter, when the user starts creating a mail by key operation from the input unit 1 (step A5), the function end control unit 22 accesses the mail storage unit 31 to determine whether there is a stored input mail. (Step A6). If there is no stored mail, mail creation is started in a new state as before (step A7). If there is a stored mail, a display for confirming to the user via the display character control unit 23 whether to “restore the stored mail?” Is performed (step A8).

  If the user performs an operation of selecting “NO” in response to this display, the stored mail is not read and mail creation is started in a new state (step A7). At this time, the stored mail is deleted via the mail storage unit 31. On the other hand, if the user performs an operation of selecting “YES” for the display in step A8, the function end control unit 22 acquires the stored mail via the mail storage unit 31 and displays it via the display character control unit 23. By displaying on the section 4, the creation of the mail is started in a state where the content of the stored mail is taken in (step A9).

  As a result of the above flow, in the case where the mail creation is terminated because the user accidentally pressed the “end key” continuously during the mail creation (step A1 → step A2 → step A3), the next mail creation is performed. By starting, it becomes possible to return to the state before the end (step A1). On the other hand, when the user gives an instruction after confirming the end of mail creation, the content of the input mail is deleted and is not stored in the mail storage unit 31, so that security can be improved.

  In the above embodiment, it is determined that the case where the “end key” is continuously pressed is a high possibility that the user has accidentally pressed the “end key” continuously during mail creation. However, when temporarily interrupting the creation of the mail and using another function (for example, a telephone function) of the cellular phone, the mail being created is saved by continuously pressing the “end key”. It can also be used as a method of reading the stored mail after the use of another function is completed and restarting the mail creation.

  Alternatively, when the user finishes creating the mail, it is used as a means for selecting whether to save or delete the mail that is being created in consideration of security. It is also possible to realize a method of saving data by continuously pressing "".

  In the above embodiment, the screen at the time of mail creation has been described. However, the present invention is not limited to mail, but can be applied to all cases of character input (such as memos).

  In addition, a program for executing the character data creation processing operation described in the above embodiment is stored in the storage unit 3, and the control unit 2 having a computer function executes the program in the above example. It can be realized as a mode of performing the described operation.

It is a principal part block diagram of the mobile telephone apparatus which shows embodiment of this invention. It is a flowchart which shows the screen transition image at the time of mail preparation by this embodiment.
