Description

  The present invention relates to an electronic device capable of executing a plurality of applications and a notification method in the electronic device.

  Currently, electronic devices such as portable terminals are configured to execute a wide variety of applications. Examples of applications that can be executed by the mobile terminal include e-mail, calendar, address book, web browser, map and GPS navigation, music playback, and games.

  However, although the conventional mobile terminal can execute various applications as described above, since the mobile terminal is usually configured to be small in size due to a request for usability, it is necessary for executing the requested application. It was naturally difficult to increase the capacity of a memory for storing information. Therefore, the conventional portable terminal is basically configured to execute only one application at a time. That is, for example, if the calendar application is to be executed while the e-mail application is being executed, the mobile terminal cannot execute the e-mail application and the calendar application at the same time. After that, there was a first disadvantage that the calendar application had to be executed again.

  In order to eliminate such a first disadvantage, there is known a portable terminal that temporarily suspends an application that is currently being executed and waits for another application to be executed during that time. Such a mobile terminal is configured to execute another application while waiting for the interrupted application, and to execute the interrupted application again in the state when the interruption is made when the other application ends. It was.

However, as shown above, the memory capacity of a normal mobile terminal is small, so if you interrupt a running application and wait to run another application, the memory usage of the newly running application In some cases, the sum of the memory usage of the waiting application and the memory usage of the newly executed application may exceed the maximum memory capacity of the mobile device. There was a second disadvantage of being unable to do so. In particular, such a second disadvantage is remarkable in a portable terminal capable of executing a new application in a state in which a plurality of applications are suspended and in a standby state. As a technique for solving the second disadvantage, for example, there is a technique disclosed in Patent Document 1.
Japanese Patent Laid-Open No. 10-63567

  In Patent Document 1, when execution of a new application is requested in a state where a plurality of applications are being executed, it is determined whether or not the memory capacity necessary for executing the new application exceeds the remaining memory capacity. When the remaining memory capacity is smaller than the memory capacity necessary for executing a new application, a memory shortage display method for notifying the fact and displaying the memory usage status of the application being executed is disclosed.

  That is, in the memory shortage display method disclosed in Patent Document 1, when the memory capacity necessary for executing a new application is insufficient, the memory usage of each application being executed by the user is displayed. It is necessary to perform an operation such as manually ending the execution of an application that uses the most memory capacity.

  However, in the memory shortage display method disclosed in Patent Document 1, only the memory usage of each application being executed by the user is displayed. Therefore, if the user terminates any application being executed, It is impossible to know whether a new application that has requested execution can be executed. In other words, even if the execution of any one of the currently running applications is terminated, if the memory capacity necessary for the execution of a new application for which further execution is requested is insufficient, There was a third disadvantage that new applications could not be executed.

  In order to eliminate the disadvantages described above, the present invention can suitably know which application that is being executed can be executed and a new application that is requested to be executed can be executed. An object is to provide an electronic device and a notification method in the electronic device.

  The electronic device of the present invention includes a nonvolatile memory that stores a plurality of applications, an execution unit that executes an application requested to be executed among the plurality of applications stored in the nonvolatile memory, and the execution request. A volatile memory for storing information necessary for executing the new application, and updating of a new application among the plurality of applications in a state where at least one of the plurality of applications is executed by the execution unit.

Control is performed.

  Preferably, in a state in which two or more applications among the plurality of applications are simultaneously executed by the execution unit, the determination unit performs a new application among the plurality of applications for each application being executed. It is determined whether the information amount of information necessary for further execution of the program exceeds an allowable value of the information amount that can be stored in the volatile memory when it is assumed that the execution of each application being executed is terminated. The control unit notifies the result of determination by the determination unit for each application by the notification unit at the same time.

  Preferably, the control unit causes the determination unit to determine the amount of information necessary for further execution of a new application among the plurality of applications for all of the applications being executed. The determination unit determines the result of determination by the notification unit, except when it is determined that the allowable value of the amount of information that can be stored in the volatile memory when it is assumed that the execution of each application is terminated. It is characterized by notifying.

  Preferably, the control unit causes the determination unit to determine the amount of information necessary for further execution of a new application among the plurality of applications for a part of each application being executed. It is determined that the allowable value of the amount of information that can be stored in the volatile memory when it is assumed that the execution of each application being executed is terminated, and for the remaining part of each application being executed, The amount of information necessary for further execution of a new application among the plurality of applications is an allowable amount of information that can be stored in the volatile memory when it is assumed that the execution of each application being executed has been terminated. When it is determined that the value exceeds the value, a result of determination by the determination unit for a part of each application being executed is notified to the notification unit. More informed, the judgment unit notifies non or limited to notification by said notification unit results of the determination by the for the remaining part of each application being executed, characterized in that.

  Suitably, the said control part alert | reports the result of determination by the said determination part by the said alerting | reporting part according to a predetermined priority.

  Preferably, the control unit attempts to make a further execution request for a new application among the plurality of applications in a state where at least one of the plurality of applications is executed by the execution unit, or When requested, the determination unit makes a determination.

  Preferably, the information processing apparatus further includes a display unit, and the control unit performs notification by the notification unit by displaying a result of determination by the determination unit on the display unit.

  A notification method in an electronic device according to the present invention is a notification method in an electronic device capable of executing a plurality of applications, and is a new one of the plurality of applications in a state where at least one of the plurality of applications is executed. Whether or not the amount of information necessary for further execution of the current application exceeds the allowable value of the amount of information that can be stored in the volatile memory on the assumption that the execution of the running application is terminated A determining step for notifying, a notifying step for notifying a result of the determination in the determining step, and a control step for varying a notifying method of the determination result in the notifying step according to the determination result in the determining step. It is characterized by having.

  According to the present invention, it is possible to know which application that is being executed can be executed by terminating which application is being executed.

  Hereinafter, the portable terminal 100 as an example of the electronic apparatus of the present invention will be described. FIG. 1 shows an example of a configuration example of the mobile terminal 100. As illustrated in FIG. 1, the mobile terminal 100 includes a nonvolatile memory 11, a volatile memory 12, an execution unit 2, a display unit 3, an operation unit 4, a determination unit 5, a notification unit 6, a lighting unit 7, and a control unit 8. Have.

  The portable terminal 100 includes a nonvolatile memory 11 and a volatile memory 12 as a storage unit that stores various data regarding operations. The non-volatile memory 11 is a rewritable memory such as a flash memory, and the data does not disappear even when the power is turned off. The nonvolatile memory 11 stores programs for various applications that operate on the mobile terminal 100. Examples of applications stored in the nonvolatile memory 11 include a music application, a TV application, a radio application, a location information acquisition application, an e-mail application, a web browser application, a game application, and a function setting application.

  The music application is an application that reproduces music data separately stored in the nonvolatile memory 11 and outputs it from an audio output unit (not shown in FIG. 1).

  The TV application and the radio application reproduce a television broadcast wave or a radio broadcast wave received by an antenna not shown in FIG. 1, and display a video on the display unit 3 or output a sound from the audio output unit in accordance with this. Application.

  The position information acquisition application, for example, causes a GPS (Global Positioning System) receiving unit (not shown) to communicate with a GPS satellite to acquire current position information where the mobile terminal 100 is currently located, or to display the acquired current position on a map. It is an application that displays.

  The e-mail application is an application that has an e-mail creating function for creating an e-mail, and performs wireless communication with a mail server via, for example, a communication unit (not shown in FIG. 1) to send and receive e-mail.

  The web browser application is an application that performs wireless communication with various web servers via a communication unit, downloads web page data, and displays the web page on the display unit 3.

  The game application is an application that executes a game program. The function setting application is, for example, a setting related to each function of the mobile terminal 100 (for example, a setting of a wallpaper displayed on the display unit 3 when the mobile terminal 100 is in a standby state, or a ring tone to be notified when a voice call is received) This is an application for setting (for example, setting the volume of a ringtone).

  The volatile memory 12 is a memory that temporarily stores programs and data that are information necessary for the execution of each application described above. When the application execution is completed, the temporarily stored programs and data are stored in the volatile memory 12. It is erased under the control of the control unit 8. The volatile memory 12 has a predetermined maximum memory capacity, but each application described above has a memory capacity that needs to be stored on the volatile memory 12 at the time of execution. The memory capacity does not exceed the maximum memory capacity.

  The execution unit 2 executes an application requested to be executed by a user operation or the like using the operation unit 4 described later, among various applications stored in the nonvolatile memory 11 described above. Further, when executing the various applications, the execution unit 2 can interrupt the application being executed and newly execute another application in a superimposed manner.

  Specifically, for example, when the execution of the electronic mail application is requested during execution of the music application, the execution unit 2 temporarily interrupts the music application and executes the electronic mail application.

  However, since the application is still being executed even when the application is interrupted, the application requires a memory capacity on the volatile memory 12 that is the same as that being executed.

  The execution unit 2 must prevent the total memory capacity required for the suspended and executing application from exceeding the maximum memory capacity of the volatile memory 12. Therefore, an application that requires a memory capacity larger than the remaining memory capacity obtained by subtracting the memory capacity used by the suspended and executing application from the maximum memory capacity of the volatile memory 12 is newly added. When an execution request is made, the newly requested application cannot be executed unless one of the suspended and running applications is terminated.

  Note that the termination of the application mentioned above means that the execution of the application is completely terminated, unlike the interruption. That is, the application to be terminated completely erases the memory of the volatile memory 12 used during execution.

  The display unit 3 is a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display, and displays a screen related to the operation according to various operations of the mobile terminal 100. For example, information on a call destination is displayed when a voice call is made, information on a call destination is displayed when a call is received, and a screen corresponding to each application is displayed when the execution unit 2 executes various applications.

  The operation unit 4 is an input device such as a numeric keypad or a cross key, and accepts user input during various operations of the mobile terminal 100. In addition, the operation unit 4 may be, for example, a touch sensor arranged so as to overlap the display unit 3.

  When the determination unit 5 assumes that, during execution or suspension of at least one application, the memory capacity (information amount) necessary for execution of the new application has terminated the application being executed or suspended It is determined whether or not the remaining memory capacity (allowable amount of information) of the volatile memory 12 is exceeded. When the result of this determination is notified by the notification unit 6 to be described later, when the execution of a new application is requested when at least one application is being executed or is interrupted, the user is executing or interrupted. If any of the applications is terminated, it can be determined whether the memory capacity required to execute the new application does not exceed the remaining memory capacity of the volatile memory 12. The determination process of the determination unit 5 will be described in detail later.

  The notification unit 6 notifies the result of determination by the determination unit 5 to the user by various means such as display, vibration, alarm, and light emission. In addition, in this embodiment, although the alerting | reporting part 6 demonstrates the aspect notified via the display part 3, this invention is not restricted to this, The alerting | reporting part 6 lights the operation part 4 by the lighting part 7. FIG. May be notified by other means, or may be notified by other means.

  The lighting unit 7 is a light emitting device such as an LED (Light Emitting Diode) that can illuminate the operation unit 4, and is disposed inside the operation unit 4 formed of, for example, a translucent or transparent member. It operates as a means of notification of the unit 6.

  The control unit 8 is a central processing unit that controls the mobile terminal 100 in an integrated manner. That is, at the time of various operations of the mobile terminal 100, each configuration of the mobile terminal 100 as described above, that is, the nonvolatile memory 11, the volatile memory 12, the execution unit 2, the display unit 3, the operation unit 4, the determination unit 5, and the notification unit 6 and the lighting part 7 are controlled to execute processing for performing each operation.

  FIG. 2 is a diagram illustrating an example of the appearance of the mobile terminal 100. As shown in FIG. 2, in the mobile terminal 100, an upper housing 101 and a lower housing 102 are connected by a hinge portion 103 so as to be opened and closed. 2A shows a state where the casing of the portable terminal 100 is opened, and FIG. 2B shows a state where the casing of the portable terminal 100 is closed. The upper housing 101 has a display unit 3. The lower housing 102 has an operation unit 4 such as a numeric keypad or a cross key.

  Next, the determination process of the determination unit 5 will be described. As described above, when the determination unit 5 assumes that the memory capacity necessary for executing a new application is terminated during execution or suspension of at least one application. It is determined whether the remaining memory capacity of the volatile memory 12 is exceeded. More specifically, the maximum memory capacity of the volatile memory 12 is x, the total memory capacity required for execution of each application being executed or suspended is y, and the determination is made among the applications being executed or suspended. When the memory capacity necessary for executing any one of the applications that are the target of execution or suspension is α and the memory capacity necessary for executing the new application is z, the determination unit 5 determines that the value of z is ( It is determined whether or not the value of (xy−α) is exceeded. When the determination unit 5 determines that the value of z does not exceed the value of (x−y−α), the memory capacity necessary for executing the new application is determined as the target of determination being executed or interrupted. Since the remaining memory capacity of the volatile memory 12 when it is assumed that the current application has been terminated is not exceeded, when the execution or suspension of the application that is the object of the determination is terminated, On the contrary, if the fixed part 5 determines that the value of z exceeds the value of (x−y−α), the memory capacity necessary for executing the new application is Since the remaining memory capacity of the volatile memory 12 when it is assumed that the running or suspended application that is the object of determination has been terminated is exceeded, This means that even if the execution or suspension of an application that is being executed or suspended is terminated, the new application cannot be executed.

  Note that the timing at which the determination unit 5 performs the determination process is not particularly limited in the present invention, but the most natural timing at which the determination unit 5 performs the determination process is, for example, during execution or suspension of at least one application The timing at which the user newly requested to execute the application or the timing at which the user requested was mentioned.

  As an example of the timing at which the user newly requests execution of an application, the user operates the operation unit 4 while the icons of the applications listed on the menu screen displayed on the display unit 3 are displayed. The timing at which an icon of an application to be newly executed is selected from these icons can be considered. Further, the timing at which the user newly requested execution of the application may be the timing at which the application related to the selected icon is determined by the operation of the operation unit 4.

  Next, a notification method of the notification unit 6 will be described. The notification unit 6 notifies the user of the determination result of the determination unit 5 as described above. Here, the notification unit 6 displays the determination result on the display unit 3 to notify the user. A mode of performing is described. Here, an example of notification by the notification unit 6 when the determination unit 5 makes a determination at a timing when the user tries to request execution of a new application in a state where at least one application is executed or interrupted. Will be explained.

  The notification unit 6 causes the display unit 3 to display a notification screen 200 as shown in FIG. 3, for example, based on the result of the determination performed by the determination unit 5 at the timing when the user is about to request execution of a new application. This is notified.

  As shown in FIG. 3A, the notification screen 200 includes an application name display field 201 in which the name of the application is shown, a determination result icon 202, and an emphasis display 203. The application name display column 201 is a column in which names of various applications stored in the nonvolatile memory 11 are listed. The determination result icon 202 is an icon indicating the determination result of the determination unit 5 for each application being executed or interrupted displayed in the application name display field 201 with “◯” and “X”. “◯” is executed by the user when it is determined that the value of z in the example shown above does not exceed the value of (xy−α), that is, when the execution or interruption of the application is terminated. Is an icon indicating that the requested new application can be executed. On the other hand, “x” is executed by the user when it is determined that the value of z in the example shown above exceeds the value of (xy−α), that is, even if the execution or interruption of the application is terminated. This icon indicates that the requested new application cannot be executed. In this manner, the determination result of the determination unit 5 for the application being executed or interrupted is displayed on the display unit 3. In this case, determination results of the determination unit 5 for two or more applications are simultaneously displayed on the display unit 3. It should be noted that an application without “O” or “×” is an application that has not been executed or interrupted in the first place and is not subject to determination by the determination unit 5. The highlight display 203 is a display for identifying an application selected by the operation of the operation unit 4 by the user, that is, an application for which a new execution request is about to be made.

  As described above, the notification screen 200 shown in FIG. 3A shows the following information to the user. First, an e-mail application (“e-mail” on the notification screen 200), a web browser application (“browser” on the notification screen 200), a radio application (“radio” on the notification screen 200), a function setting application (“ “Function setting”) is associated with an icon of “◯” or “×”, indicating that these applications are being executed or suspended. On the other hand, since the music application (“music player” in the notification screen 200) is not associated with any of the icons “◯” and “x”, this indicates that the music application is not being executed or interrupted. Further, since the TV application is highlighted by the highlighting 203, it means that the TV application is an application selected by the operation of the operation unit 4 of the user, that is, an application to be newly requested for execution.

  The e-mail application, the radio application, and the function setting application associated with “◯” indicate that the TV application that is newly requested to be executed can be executed when the execution or interruption is completed. . On the other hand, a web browser application associated with “x” indicates that a TV application that is newly requested to be executed cannot be executed even if execution or interruption is terminated.

  Next, an operation example of the mobile terminal 100 of the present embodiment will be described. The flowchart is shown in FIG.

  Step ST1: The execution unit 2 executes one of the applications stored in the non-volatile memory 11 in response to an operation via the user operation unit 4 or the like.

  Step ST2: When there is further operation or the like through the user operation unit 4 in this state, the control unit 8 controls the display unit 3 to display a menu screen listing the applications stored in the nonvolatile memory 11 Let

  Step ST3: In this state, any of the applications listed on the menu screen is selected by a further operation or the like via the operation unit 4 of the user (that is, an application to be requested for execution is selected). The icon of the selected application is highlighted by the highlight display 203.

  Step ST4: Whether the determination unit 5 exceeds the remaining memory capacity of the volatile memory 12 when it is assumed that the memory capacity necessary for executing the application selected in step ST3 has terminated the application executed in step ST1. Determine whether or not. If there is an interrupted application other than the application executed in step ST1, the determination unit 5 also performs the determination for the interrupted application. That is, the determination unit 5 determines whether or not the memory capacity necessary for executing the new application selected in step ST3 exceeds the remaining memory capacity of the volatile memory 12 assuming that the suspended application is terminated. Determine whether.

  Step ST5: The notification unit 6 notifies the determination result of the determination unit 5 in step ST4 by the method described above. The notification method is not limited here.

  Step ST6: The control unit 8 determines whether any other new application has been selected by a further operation or the like via the user operation unit 4 (that is, an application to be requested for execution is determined). Selected). If another new application is selected, the process returns to step ST4 to make the same determination, and on the other hand, another new application is selected by further operation through the operation unit 4 of the user. If the display of the menu screen displayed in step ST2 is terminated without any change, the portable terminal 100 returns to standby and the operation process is terminated.

  As described above, according to the mobile terminal 100 of the present embodiment, when at least one application is being executed or is interrupted, if another application is requested to be executed repeatedly, the determination unit 5 Determines whether or not the memory capacity necessary for executing the new application exceeds the remaining memory capacity of the volatile memory 12 when it is assumed that the currently executing or suspended application is terminated. Since the notification is performed based on the determination result, the user can determine which of the running or suspended applications can execute the new application requested to be executed. Prior to executing a new application, it can be suitably determined. That is, usability of the mobile terminal 100 when executing an application is improved.

  In the present embodiment, as shown in the notification screen 200, the determination result of the determination unit 5 for two or more running or suspended applications is displayed on the display unit 3 at the same time. It is possible to quickly determine which of the two or more running or suspended applications can be executed if a new application requested to be executed can be executed.

  In addition, this invention is not limited to embodiment mentioned above. That is, when implementing the present invention, various modifications, combinations, sub-combinations, and alternatives may be made to the components of the above-described embodiments within the technical scope of the present invention or an equivalent scope thereof.

  For example, in the mobile terminal 100 according to the present embodiment, when at least one application is being executed or interrupted and another application is requested to be executed repeatedly, the determination unit 5 first indicates However, the present invention is not limited to this. For example, in a state where at least one application is being executed or suspended. When a request for execution is made with another application overlaid (for example, when the application highlighted by the highlighting 203 is confirmed by further operation of the operation unit 4), the determination unit 5 is as described above. It is good also as a structure which alert | reports and the alerting | reporting part 6 alert | reports based on the determination result.

  Further, in the notification screen 200 shown in FIG. 3A, the applications in the application name display column 201 are randomly arranged. However, the present invention is not limited to this, and the application names according to a predetermined priority order. It is also possible to rearrange and display the applications in the display column 201. For example, the application “E” is “○” so that the application whose determination result icon 202 is “◯” and the application “×” are grouped together, that is, as shown in FIG. , “Radio application” and “Function setting application” are displayed at the top of the screen, “×” applications are displayed together at the bottom of the screen, and “○” applications are displayed in order of frequency of use and memory capacity required for execution. Or you may. The user can preferably determine which of the running or suspended applications should be terminated.

  In addition, the mobile terminal 100 according to the present embodiment can execute an application that is newly requested to be executed if the execution or interruption is temporarily ended among a plurality of applications that are being executed or are interrupted. When the application determined by the determination unit 5 and the application determined by the determination unit 5 that the application to be newly requested for execution cannot be executed even if the execution or interruption is finished are mixed The determination result for any application is configured to be displayed on the display unit 3 on the display unit 3, but the present invention is not limited to this. If the execution or suspension of the application is temporarily terminated, a new execution request may be made. And you can execute it has application only the determination result of the determination application by the determination unit 5 may be configured to display on the display unit 3 on the display unit 3.

  In other words, in the present embodiment, as shown in FIG. 3A, both “O” and “X” of the determination result icon 202 are displayed on the notification screen 200. In addition to this, when “O” and “X” are mixed, the display of “X” and the corresponding application itself is not performed. That is, “O” and the corresponding application are not displayed. It is also possible to adopt a configuration in which only Accordingly, the user can preferably know to the user which application to be terminated from among the applications being executed or suspended.

  Further, as a result of the determination by the determination unit 5, it is assumed that all applications that are being executed or suspended are applications that can execute an application that is newly requested to be executed if the execution or interruption is temporarily ended. When it is determined by the determination unit 5, it may be configured not to notify the determination result itself by the notification unit. This allows the user to recognize that all applications in the running or suspended application can execute the application that is being requested to run once the execution or suspension is complete, It is possible to suitably suppress unnecessary display on the display unit 3.

  The notification screen 200 is an example, and the present invention is not limited to this. That is, the determination result icon 202 not only represents whether execution is possible by “O”, “X”, but also, for example, characters, symbols such as “OK” and “NO”, and other applications intuitively for the user. It may be a display of an icon or the like that can convey whether execution is possible. Further, the highlight display 203 is not limited to a display filled with diagonal lines, and any other display may be used as long as it can distinguish which application is specified.

  In addition, the notification method of the notification unit 6 of the present invention is not limited to the display on the display unit 3 as described above, for example, the application subject to determination by the lighting unit 7 that can be lit in different colors according to the determination result. The lighting may be performed on the operation unit 4 (so-called shortcut key) to which the execution operation is assigned, notification by voice by a voice output unit (not shown in FIG. 1), or notification by vibration by a vibrator (not shown in FIG. 1).

  In the present embodiment, the portable terminal 100 is shown as an example of the present invention. However, the present invention is not limited to this, and for example, a PDA, a notebook computer, and other devices configured to be able to execute a plurality of applications. It can also be applied to communication equipment.
