Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program.

  Currently, information processing devices such as smartphones are rapidly spreading. With the spread of such information processing apparatuses, the information displayed on the display screen of the information processing apparatus also has an information amount and expressive power comparable to the information displayed on the display screen of a personal computer. It is coming.

  For information displayed on the information processing apparatus, for example, the order of display may be properly used depending on the display priority.

  For example, when an application is activated and information about the application is displayed on the screen, when there is an incoming call, the telephone application is activated and information indicating that the incoming call has been displayed. ing. In this case, the telephone application has a higher display priority than a certain application.

  For example, when an error occurs during a call, an error message is displayed on the screen of the information processing apparatus.

  Therefore, in such an information processing apparatus, the display priority of the telephone application is higher than that of the normal application, and the display priority of the application related to the error is higher than that of the telephone application.

  By properly using the order of information displayed according to the display priority, for example, it is possible to make information notification to the user faster than in the case where such a case is not performed, It is possible to quickly notify the user of high-level information.

  On the other hand, in the information processing apparatus, various applications can be added by downloading. By executing the downloaded application in the information processing apparatus, it is possible to receive various additional services such as exchanging information with other users and playing games.

  As a technique related to such an information processing apparatus, for example, there are the following techniques.

  That is, there is an application program management device that exchanges an application that is activated but not displayed and an application that can be switched and displayed by a display switching button based on user information, use frequency information, use date information, and the like. is there.

  According to this technology, for example, a large number of application programs can be activated.

  In addition, a management unit is provided in the in-vehicle device or the smartphone, and the management unit selects an application to be activated and displayed according to an external input to the in-vehicle device or the smartphone based on the display priority definition, and the display unit of the in-vehicle device or the smartphone There is an in-vehicle device that can be displayed.

  According to this technology, for example, it is possible to determine what screen should be output in an in-vehicle device or a smartphone, and to control the screen, thereby providing higher safety and convenience. Is done.

  Furthermore, there is a portable terminal device that determines whether an application screen is preferentially displayed but an incoming notification is preferentially displayed based on a key input time interval for an active application when data such as mail arrives.

  According to this technology, for example, the screen display of an incoming call notification during application activation can be dynamically changed to an optimal display state according to how the application is used.

  However, in the information processing apparatus, for example, when an additional application having the same display priority as that of the telephone application is downloaded, the information regarding the additional application cannot be displayed when the information regarding the telephone application is displayed. When the display priorities are the same, for example, information regarding the telephone application that has been executed first is displayed on the screen of the information processing apparatus, information about the additional application that has been executed later is not displayed, and the telephone application ends. Such information will be displayed later.

  Therefore, in the information processing apparatus, even when a new service is added by downloading, information regarding the added service may not be displayed depending on the display priority. Therefore, in such an information processing apparatus, even if the information is downloaded, information regarding the downloaded service is not displayed, so it is difficult to say that the information processing apparatus is sufficiently compatible with the addition of the service.

  The technology that allows the application that can be displayed to be exchanged with the application that does not perform the display is, for example, the technology that exchanges two applications based on user information, usage frequency information, etc., and mentions the display priority. It has not been. For this reason, in this technique, for example, when an additional application having the same display priority as that of the telephone application is added, information regarding the additional application cannot be displayed when information regarding the telephone application is displayed. Therefore, it cannot be said that such a technique is sufficiently compatible with the addition of services.

  In addition, the technology that selects the application to be activated and displayed based on the display priority definition and displays the application on the display unit of the in-vehicle device or the smartphone can also be applied to two applications having the same display priority definition. There is no mention of what to deal with. Therefore, such a technique may not be displayed depending on the display priority of the additional application, and it is difficult to say that the technique sufficiently corresponds to the addition of the service.

  Furthermore, in the technology for determining whether to preferentially display the application screen or to preferentially display incoming notifications such as e-mails, the determination is based on the key input time interval for the running application, and the display priority is mentioned. It has not been. Therefore, in such a technique, information regarding the additional application may not be displayed, and it is difficult to say that the technology sufficiently supports the addition of services.

  Accordingly, one disclosure is to provide an information processing apparatus, an information processing method, and an information processing program that can display information about an application added by downloading.

  One disclosure is to provide an information processing apparatus, an information processing method, and an information processing program that can cope with the addition of a service.

  One disclosure includes a display unit, a first application program, and a control unit that executes a second application program added by downloading, and the control unit executes the first application program and executes the first application program. Display priority indicating a display order when information related to one application is displayed on the display unit, and display when information related to the second application is displayed on the display unit by executing the second application program When the display priority indicating the order is the same, when the second application is executed after executing the first application program, the display priority of the first or second application program is changed.

  According to one disclosure, it is possible to provide an information processing apparatus, an information processing method, and an information processing program that can display information about an application added by downloading. Further, according to one disclosure, an information processing apparatus, an information processing method, and an information processing program that can cope with addition of a service can be provided.

  Hereinafter, modes for carrying out the present invention will be described.

[First Embodiment]
A first embodiment will be described. FIG. 1 illustrates a configuration example of the information processing apparatus 100 according to the first embodiment. The information processing apparatus 100 is, for example, a smartphone, a feature phone, a tablet, or a personal computer.

  The information processing apparatus 100 includes a control unit 110 and a display unit 170.

  The control unit 110 executes the first application program and the second application program added by downloading.

  With respect to the first application program, there is a display priority indicating a display order when information related to the first application is displayed on the display unit 170 by executing the first application program. In addition, the second application program also has a display priority indicating the display order when information related to the second application is displayed on the display unit 170 by executing the second application program.

  When the two display priorities are the same, the control unit 110 changes the display priority of the first or second application program when executing the second application program after executing the first application program.

  By changing the display priority of the first or second application program, for example, the display priority of the first application program may be lower than the display priority of the second application program. Since the display priority of the first application program is lower than the display priority of the second application program, it is possible to display information related to the second application that has been started later. In such a case, the control unit 110 can display information on the second application program on the display unit 170.

  Further, due to the change in display priority, for example, the display priority of the second application program may be higher than the display priority of the first application program. This makes it possible to display information related to the second application that has started execution later. In such a case, the control unit 110 can display information on the second application program on the display unit 170.

  As described above, the information processing apparatus 100 can display information related to the second application added by downloading by changing the display priority.

  In addition, since the information processing apparatus 100 can display information related to the second application added later by downloading, the information processing apparatus 100 can sufficiently cope with the additional service.

[Second Embodiment]
Next, a second embodiment will be described.

<Configuration example of information processing apparatus>
FIG. 2 is a diagram illustrating a configuration example of the information processing apparatus 100. The information processing apparatus 100 is a portable terminal device such as a smartphone, a feature phone, a tablet, or a game device. The information processing apparatus 100 may be a personal computer, for example.

  Further, the information processing apparatus 100 can download an application program by wireless communication or wired communication.

  In the second embodiment, the information processing apparatus 100 will be described as a smartphone that can download an application program through wireless communication.

  As illustrated in FIG. 2, the information processing apparatus 100 includes a CPU (Central Processing Unit) (or control unit) 110, a ROM (Read Only Memory) 120, a RAM (Random Access Memory) 130, a memory 140, a wireless unit 160, an antenna. 161 and a display unit 170. The CPU 110, the ROM 120, the RAM 130, and the memory 140 are connected to each other via the internal bus 150.

  For example, the CPU 110 reads a program stored in the ROM 120, loads it into the RAM 130, and executes the loaded program. For example, the CPU 110 reads a download program stored in the RAM 130 or the memory 140, loads it into the RAM 130, and executes the loaded download program.

  The CPU 110 includes an application layer 111 and an OS (Operating System) layer 112, and executes programs loaded by the two layers 111 and 112.

  The application layer 111 executes various application programs according to instructions from the OS layer 112, for example. In the example of FIG. 2, the application layer 111 executes the preceding application program 113 and the additional service application 114.

  Here, the preceding application program 113 is, for example, a program stored in the ROM 120 and executable in the application layer 111. In the second embodiment, a telephone application or a buzzer application will be described as an example of the preceding application program 113.

  The additional service application program 114 is an application program related to a service added by downloading, for example. The additional service application program 114 is an application added after the preceding application program 113. The additional service application program 114 is stored in the RAM 130 or the memory 140 according to an instruction from the application control unit 115, for example. In the present embodiment, an extension service application and an emergency call automatic transmission application will be described as examples of the additional service application 114.

  The preceding application program 113 is one of programs executed by the CPU 110, and the function of the preceding application is realized in the information processing apparatus 100 by being executed in the application layer 111. The additional service application program 114 is also executed in the application layer 111 of the CPU 110, whereby the function of the additional service application is realized in the information processing apparatus 100.

  In the following description, the preceding application program 113 and the preceding application may be used without being distinguished from each other. Further, the additional service application program 114 and the additional service application may be used without being distinguished from each other.

  For example, the OS layer 112 reads a program loaded on the RAM 130, outputs the program to the application layer 111, and instructs the application layer 111 to execute the program. The OS layer 112 includes an application control unit 115 and a priority service activation agent 116.

  The application control unit 115 is a functional block that controls execution of application programs 113 and 114 executed in the application layer 111, for example. Further, the application control unit 115 manages, for example, display priority, and displays information related to the applications 113 and 114 executed in the application layer 111 on the display unit 170 according to the display priority. The display priority indicates, for example, the display order when information related to the applications 113 and 114 is displayed.

  FIG. 3 is a diagram illustrating an example of display priority. As shown in FIG. 3, the display priority is divided into five display layers from “normal application” to “system error”. As for the display priority, “normal application” is the lowest and “system error” is the highest. For this reason, for example, when an “incoming application” is displayed on the screen and there is an incoming call, information related to the “telephone” application having a higher display priority than the “ordinary application” is displayed.

  In FIG. 3, “Toast” is a display function (or application) that displays text such as “Registered” or “Downloaded” on the screen, and then turns off the display. It is. Since “toast” has a higher display priority than “telephone”, even when information related to the “telephone” application is displayed on the screen, a display related to “toast” can be displayed on the screen.

  In addition, the “system overlay” is a display function (or application) that displays various information such as usage rate information of the CPU 110 superimposed on other information (overlaid). Furthermore, the “system error” is, for example, a display function (or application) that displays information about an error.

  In the application control unit 115, for example, information on display priority is stored in the memory 140, and information on the applications 113 and 114 executed in the application layer 111 is displayed on the display unit 170 based on the display priority. I have to. Details of processing performed by the application control unit 115 will be described later.

  The priority service activation agent 116 is, for example, a functional block that determines whether the additional service application 114 has been activated (or the execution of the additional service application program 114 has started). For example, when receiving a priority display application activation notification from the application control unit 115, the priority service activation agent 116 detects activation of the additional service application 114. For example, when the priority service activation agent 116 receives an application termination notification from the application control unit 115, the priority service activation agent 116 detects the termination of the additional service application 114. Details of processing performed by the priority service activation agent 116 will be described later.

  The ROM 120 stores, for example, a preceding application program 113. For example, the RAM 130 is loaded (or stored) with programs 113 and 114 that are executed by the CPU 110. The RAM 130 stores various data as a work area when the CPU 110 executes the programs 113 and 114. The memory 140 stores, for example, the display priority shown in FIG. The downloaded additional service application program 114 is stored in the RAM 130 or the memory 140.

  Radio section 160 converts a control signal or the like output from CPU 110 into a radio signal, and transmits the converted radio signal to the base station via antenna 161. Radio section 160 extracts a download program, a control signal, and the like from the radio signal received from the base station via antenna 161, and outputs the extracted download program, control signal, and the like to CPU 110. In this case, the CPU 110 stores the download program received from the wireless unit 160 in the RAM 130 or the memory 140.

  The display unit 170 is, for example, a liquid crystal display screen, and displays information related to the applications 113 and 114 executed in the application layer 111 under the control of the application control unit 115.

<Operation example>
Next, an operation example in the information processing apparatus 100 will be described. 4 is a sequence diagram showing an example of the overall operation of the information processing apparatus 100, FIG. 5 shows an example of processing in the priority service activation agent 116, and FIGS. 6A and 6B show examples of processing in the preceding application 113, respectively. Yes. Hereinafter, description will be given in this order.

  In the following operation example, the display priority of the preceding application 113 and the additional service application 114 is the same.

  Further, in the following operation example, it may be described that the preceding application 113 performs processing. For example, the CPU 110 executes the preceding application program 113 to realize the function of the preceding application. In this operation example, the CPU 110 or the preceding application 113 performs processing. Sometimes used without distinction. Similarly, the additional service application 114 may be used with no particular distinction as to whether the CPU 110 performs processing or the additional service application 114 performs processing. As with the preceding application 113, the application control unit 115 and the priority service activation agent 116 may be used without distinction as to whether the CPU 110 performs processing or these blocks perform processing.

<1.1 Sequence example showing overall operation example>
As shown in FIG. 4, the information processing apparatus 100 downloads the additional service application program 114 (S10). The downloaded additional service application program 114 is stored in the RAM 130 or the memory 140, for example.

  Next, the application control unit 115 activates the preceding application program 113 (S11). For example, the following processing is performed. That is, when a user operation instructing execution of the preceding application 113 is detected on the display unit 170 or reception of a control signal related to an incoming call is detected on the wireless unit 160, that fact is notified to the application control unit 115. Then, the application control unit 115 reads the preceding application program 113 from the ROM 120 and starts executing the program 113.

  Next, the preceding application 113 displays information on the application on the display unit 170 (S14). For example, the preceding application 113 can display information on the display unit 170 by generating the information related to the preceding application by executing the application program and outputting the information to the display unit 170.

  Next, the application control unit 115 activates the additional service application 114 (S15, S16). For example, the following processing is performed. That is, when the display unit 170 detects an operation for instructing execution of the additional service application by the user, the display unit 170 notifies the application control unit 150 to that effect. Upon receiving the notification, the application control unit 114 reads the additional service application program 114 from the RAM 130 or the memory 140, outputs it to the application layer 111, and instructs the execution of the program 114. As a result, the additional service application 114 is activated.

  Next, the additional service application 114 notifies the application control unit 115 of the priority display setting (S17). For example, the priority display setting requests that the information related to the additional service application 114 be displayed by notifying the application control unit 115 that the additional service application 114 has been started. For example, the additional service application 114 generates a priority display setting when starting, and notifies the application control unit 115 of the generated setting.

  Upon receiving the priority display setting, the application control unit 115 generates a priority display application activation notification, and notifies the priority service activation agent 116 of the generated notification (S18). The priority display application activation notification is, for example, a notification for notifying the priority service activation agent 116 that the additional service application 114 has been activated.

  Upon receiving the priority display application activation notification, the priority service activation agent 116 notifies the preceding application 113 of the priority service activation notification (S19). For example, the priority service activation agent 116 notifies the preceding application 113 that the preceding application 113 has been started by the notification.

  Upon receiving the priority service activation notification, the preceding application 113 determines whether or not the additional service application 114 is permissible for service control, and performs display priority control when it is determined that permissible (S20).

  The determination as to whether service control is permissible is performed, for example, as follows. That is, the preceding application 113 determines whether or not the communication carrier allows the application by performing an authentication process based on the authentication information included in the priority service activation notification (S19). In this case, the preceding application 113 extracts authentication information from the priority service activation notification (S19). The preceding application 113 compares the authentication information with authentication information corresponding to an application permitted by the communication carrier, and determines whether the two authentication information matches. Authentication information corresponding to an application permitted by the communication carrier is stored in the memory 140, for example. The preceding application 113 performs processing by appropriately reading out authentication information corresponding to the application permitted by the communication carrier from the memory 140 and comparing it with the extracted authentication information during the processing (S20).

  The display priority control is performed as follows, for example. That is, when it is determined that the additional service application 114 is capable of service control, the preceding application 113 determines to lower the display priority of the preceding application 113 by one display layer. If the preceding application 113 and the additional service application 114 have the same display priority, the additional service application 114 can be displayed by lowering the display priority of the preceding application 113 by one display layer.

  The preceding application 113 performs display priority control and notifies the application control unit 115 of the display priority lowering setting (S21).

  Upon receiving the display priority lowering setting from the preceding application 113, the application control unit 115 switches the display screen (S22). For example, the following processing is performed. That is, the application control unit 115 lowers the display priority of the preceding application 113 by one display layer based on the display priority lowering setting. Then, the application control unit 115 switches the display priority from the preceding application 113 to the additional service application 114 for information output from the application layer 111 to the display unit 170 by lowering the display priority by one display layer.

  Accordingly, the additional service application 114 can display information related to the application 114 on the display unit 170 (S23).

  Thereafter, when the additional service application 114 ends (S24), the application control unit 115 is notified of the application end of the additional service application (S25).

  Next, the application control unit 115 notifies the priority service activation agent 116 of an application end notification of the additional service application 114 (S26).

  Upon receiving the application end notification, the priority service activation agent 116 notifies the preceding application 113 of the priority service end notification of the additional service application 114 (S27). Thereby, for example, the termination of the additional service application 114 is notified to the preceding application 113.

  Upon receiving the priority service end notification, the preceding application 113 performs display priority control (S28). For example, the preceding application 113 determines to increase the display priority of the own application that has been lowered by one display layer by one display layer.

  Next, the preceding application 113 notifies the application control unit 115 of the display priority increase setting (S29).

  The application control unit 115 increases the display priority of the preceding application 113 by one display layer and switches the display screen displayed on the display unit 170 so that the information on the preceding application 113 is displayed (S30). For example, the application control unit 115 outputs information executed in the preceding application 113 from the preceding application 113 to the display unit 170 based on the display priority increase setting. Thereby, the screen is switched to the preceding application 113.

  By switching the display screen, the preceding application 113 can cause the display unit 170 to display information related to the self application 113 (S31).

<1.2 Example of operation in priority service activation agent>
FIG. 5 is a flowchart showing an operation example in the priority service activation agent 116. When the priority service activation agent 116 starts processing (S40), the priority service activation agent 116 waits for the occurrence of a priority display event (S41), and confirms reception of a priority display application activation notification or application termination notification (S42).

  For example, the priority service activation agent 116 receives a priority display application activation notification (S18 in FIG. 4) or a priority service end notification (S27 in FIG. 4) output from the application control unit 115, thereby generating a priority display event. Is detected.

  When the priority service activation agent 116 receives the priority display application activation notification (Yes in S43), the priority service activation agent 116 shifts to the priority service activation state (S44) and notifies the preceding application 113 of the priority service activation notification (S45). The processing from Yes to S45 in S43 corresponds to, for example, the processing from S18 to S19 in FIG. Thereafter, the process proceeds to S41, and the above-described process is repeated.

  Note that the transition to the priority service activation state is performed, for example, when the priority service activation agent 116 turns on the priority service activation state flag stored in the memory 140.

  On the other hand, when the priority service activation agent 116 receives the application end notification (No in S43), the priority service activation agent 116 determines whether or not the priority service activation state is set (S46). For example, the priority service activation agent 116 receives the priority display application activation notification and determines whether or not the priority service activation state is maintained. Further, the priority service activation agent 116 can be determined based on, for example, whether or not the priority service activation state flag stored in the memory 140 is on.

  If the priority service activation agent 116 maintains the priority service activation state (Yes in S46), the priority service activation agent 116 shifts to the no priority service state (S47). For example, the priority service activation agent 116 turns off the priority service activation state flag stored in the memory 140.

  Next, the priority service activation agent 116 notifies the preceding application 113 of a priority service end notification (S48). This process (S48) is a process corresponding to S27 of FIG. 4, for example. Thereafter, the process proceeds to S41 and the above-described process is repeated.

  On the other hand, when the priority service activation agent 116 is not in the priority service activation state (No in S46), the priority service activation agent 116 proceeds to S41 and repeats the above-described processing. In this case, since the additional service application 114 has not been activated, the priority service activation agent 116 waits for a priority display event (S41).

<1.3 Example of operation in the preceding application>
FIGS. 6A and 6B are flowcharts illustrating an operation example in the preceding application 113. Among these, FIG. 6A shows an operation example when a priority service activation notification is received, and FIG. 6B shows an operation example when a priority service end notification is received.

  Upon receiving the priority service activation notification transmitted from the priority service activation agent 116, the preceding application 113 starts processing (S60), and determines whether the certificate of the activation application is appropriate (S61). This process (S61) is, for example, a process corresponding to the process (S20) of whether service control is permissible. Whether or not the certificate of the startup application is appropriate can be determined, for example, based on whether or not the certificate of the additional service application 114 included in the priority service startup notification matches the certificate of the service application allowed by the communication carrier. It is.

  Regarding the processing of S61, it is only necessary to be able to determine whether or not service control is permissible, and instead of an example of using a certificate added to the additional service application program 114, a creator (APK (Application APK) that provides the additional service application 114 is used. (package) class name etc.) information may be used.

  For example, the following processing is performed. That is, when the additional service application 114 is downloaded (S10 in FIG. 4), the application control unit 115 confirms the creation source of the application 114 and sends a priority display application launch notification including information on the creation source to the priority service launch agent. 116 is notified (S18). The priority service activation agent 116 notifies the preceding application 113 of a priority service activation notification including information on the creation source (S19). The predecessor application 113 may determine whether or not the service control is possible by checking whether or not the creation source information included in the priority service activation notification is a creation source that allows service control. The information on the creation source that allows service control may be stored in, for example, the memory 140 and read and confirmed by the preceding application 113.

  If the certificate of the activation application is appropriate (Yes in S61), the preceding application 113 performs setting so as to lower the display priority of the preceding application 113 (S62).

  Then, the preceding application 113 ends the series of processes (S63).

  On the other hand, if the certificate of the activation application is not appropriate (No in S61), the preceding application 113 ends the series of processes without performing display priority control (S63).

  For example, if an unauthorized application that is not allowed by the communication carrier is to be executed as an additional service application, the preceding application 113 does not perform display priority control, and the additional service application 114 is not displayed on the screen (No in S61, S63). .

  The preceding application 113 starts processing upon receiving the priority service end notification (S70), and performs display priority increase setting (S71). For example, the preceding application 113 notifies the application control unit 115 of a display priority increase setting so as to increase the display priority by one display layer in order to restore the display priority of the preceding application 113 (S29 in FIG. 4). .

  Then, the preceding application 113 ends the series of processes (S72).

<2. Example of extension service application for telephone application>
Next, as a specific example of operation, an example will be described in which the preceding application 113 is a telephone application and the additional service application is an extension service application. The telephone application and the extension service application have the same display priority. In the example of FIG. 3, the two applications are included in the “telephone” display layer.

  FIG. 7A shows an example of a display screen displayed on the display portion 170. When the extension service application 114 is downloaded and installed as an additional service application, an “extension service” activation menu 171 is displayed on the display screen. FIG. 7A shows an example in which an extension service activation menu 171 is displayed after a telephone call. When the user operates the activation menu 171 on the screen of the display unit 170 after making a call, a menu related to the extension service shown in FIG. 7B is displayed. In the menu screen shown in FIG. 7 (B), the user can input an extension number by operating a numeric button or the like displayed on the menu, and the extension service is transmitted to the extension number by the “OK” button. Can do.

  When an extension service is received after a call is made, the activation menu 171 is displayed in color and the user is notified, and when the user operates the activation menu 171, the menu screen shown in FIG. 7B is displayed. May be.

  As information about the additional service application 114, in the example of FIG. 7B, there are a numeric button for inputting an extension number, a button for performing transfer and holding, and the like. On the other hand, as information on the preceding application 113, for example, in the example of FIG. 7A, a numeric button for inputting a telephone number, a telephone number that has been transmitted, a human-type display indicating that a telephone call is being made, an extension service There is a button for starting up.

  FIG. 8 is a sequence diagram illustrating an operation example in such a case. In FIG. 8, the same processes as those in FIG. 4 are denoted by the same reference numerals.

  The telephone application 113 displays a call screen when a call operation is performed by the user (S80). For example, a screen as shown in FIG. For example, the telephone application 113 can display the call screen by generating information related to the call screen by executing the application program and outputting the information to the display unit 170.

  Next, the telephone application 113 determines to activate the extension service application 114 when the call screen is displayed (S81). For example, when it is detected that the extension service activation menu 171 is operated on the display unit 170, the fact is notified to the telephone application 113 via the application control unit 115. The telephone application 113 can determine to activate the extension application 114 by receiving the notification.

  Next, the telephone application 113 notifies the application control unit 115 of an activation instruction for the extension service application 114 (S82). For example, when the telephone application 113 determines to activate the extension service application, the telephone application 113 generates an activation instruction for the extension service application 114 and notifies the application control unit 115 of the generated activation instruction.

  Next, the application control unit 115 instructs activation of the extension service application 114 (S15), and the extension service application 114 is activated as an additional service application.

  The subsequent processes (S15 to S31) are described in <1.1 Sequence example showing overall operation example> (for example, FIG. 4) except that the preceding application is the telephone application 113 and the additional service application is the extension service application 114. It is the same.

  When information about the telephone application 113 is displayed, the application control unit 115 can lower the display priority of the telephone application 113 (S21) and display the extension service application 114 (S22, S23). .

<3. Operation example of emergency call automatic call application for buzzer application>
Next, as a specific operation example, an example in which the preceding application 113 is a buzzer application and the additional service application 114 is an emergency call automatic transmission application will be described. Both the buzzer application and the emergency call automatic transmission application have the same display priority. In the example shown in FIG. 3, the two applications are included in the display layer of “system error”.

  FIG. 9A shows an example of a display screen of the buzzer application 113 displayed on the display unit 170. For example, when the user operates the buzzer key displayed on the display unit 170, a screen shown in FIG. 9A (hereinafter sometimes referred to as a sounding animation screen) is displayed, and a warning sound (or buzzer sound) is output. The information processing apparatus 100 may shake with the output of the warning sound.

  Examples of the information related to the buzzer application 113 include a buzzer key for starting the buzzer application 113 and a text sentence as shown in FIG.

  When a sounding animation screen as shown in FIG. 9A is displayed, when a user operates a predetermined button displayed on the display unit 170, an emergency call can be automatically transmitted to a specific telephone number. it can. FIG. 9B is a diagram illustrating an example of a display screen of the display unit 170 after an emergency call is automatically transmitted when the buzzer application 113 is executed. Information relating to the emergency call automatic call application 114 includes a menu button for automatically sending an emergency call when a buzzer is being output, display information after the automatic call is shown in FIG. 9B, and the like.

  FIG. 10 is a sequence diagram of an operation example in such a case. In FIG. 10, the same processes as those in FIG. 4 are denoted by the same reference numerals.

  The buzzer application 113 is automatically activated when the information processing apparatus 100 is powered on (S90). For example, the following processing is performed. That is, when the application control unit 115 detects that the information processing apparatus 100 is turned on, the application control unit 115 reads the buzzer application 113 from the ROM 120 and outputs it to the application layer 111. Then, the application control unit 115 instructs the application layer 111 to execute the program 113 in the application layer 111.

  On the other hand, the application control unit 115 detects the activation of the buzzer key of the buzzer application program 113 (S91). For example, the following processing is performed. That is, the application control unit 115 receives an instruction from the application layer 111 to display the buzzer key on the display unit 170 when the buzzer application program 113 is activated in the application layer 111. In response to the instruction, the application control unit 115 causes the display unit 170 to display a buzzer key. The application control unit 115 detects the activation of the buzzer key by receiving a buzzer key display instruction from the application layer 111.

  Next, when detecting the occurrence of the buzzer activation event, the application control unit 115 notifies the buzzer activation event notification to the buzzer application 113 (S92). For example, the following processing is performed. That is, when the display unit 170 detects that the buzzer key displayed on the screen has been operated, the display unit 170 notifies the application control unit 115 accordingly. Upon receiving the notification, the application control unit 115 generates a buzzer activation event notification and notifies the buzzer application 113 of the generated buzzer activation event notification.

  Next, the buzzer application 113 displays the sound animation screen on the display unit 170 and sounds the buzzer (S94). For example, the following processing is performed. That is, when the buzzer application 113 receives the buzzer activation event notification, the buzzer application 113 generates a ringing animation screen and outputs it to the display unit 170, further instructs the audio unit to output a buzzer sound, and vibrates the vibrator. In the sound unit, the buzzer sound held in the memory 140 or the like is read out and output from the speaker or the like, thereby outputting the buzzer sound from the speaker.

  On the other hand, when detecting the stop of the buzzer key (S95), the application control unit 115 notifies the buzzer application 113 of a buzzer stop event notification (S96). For example, the following processing is performed. That is, when detecting an operation to stop the buzzer sound for the buzzer key displayed on the screen, the display unit 170 notifies the application control unit 115 to that effect. When the application control unit 115 receives the notification, it detects a buzzer key stop, generates a buzzer stop event notification, and notifies the buzzer application 113 of the buzzer key stop.

  Thereafter, the emergency call automatic transmission application 114 is downloaded and installed in the information processing apparatus 100 as an additional service application (S97). The installation means, for example, that the emergency call automatic transmission application program 114 is converted into a file format executable by the CPU 110 and stored in the RAM 130 or the memory 140.

  Next, the application control unit 115 instructs activation of the emergency call automatic transmission application program 114 (S15), and activates the application 114 (S16).

  Next, when detecting the activation of the buzzer key (S98), the application control unit 115 broadcasts a buzzer activation event notification (S99). The process of S98 is the same as the process of S91, for example. The application control unit 115 broadcasts a buzzer activation event notification. In this case, the notification is notified to the buzzer application 113 and the emergency call automatic transmission application 114.

  When the buzzer application 113 receives the notification, the buzzer application 113 displays the sound animation screen, outputs a buzzer sound, and vibrates the vibrator (S100).

  The subsequent processing from S17 to S22 is the same as the processing from S17 to S22 in <1.1 Sequence Example Showing Example of Overall Operation> (for example, FIG. 4).

  Then, the display screen is switched by the application control unit 115 (S22), and the emergency call automatic transmission application 114 displays information related to the application 114 on the display unit 170 and performs automatic transmission to a specific telephone number. (S101). For example, the following processing is performed. In other words, the emergency call automatic call application 114 reads the information (for example, the text sentence shown in FIG. 9B) related to the emergency call automatic call from the memory 140 and outputs it to the display unit 170 by executing the application program. . Further, the emergency call automatic call application 114 generates a call signal addressed to a specific telephone number and transmits it to the base station via the radio unit 160 or the like.

  Next, when detecting the stop of the buzzer key (S102 in FIG. 11), the application control unit 115 generates a buzzer stop event notification and transmits it by broadcast (S103). In this case, the buzzer stop event notification is notified to the buzzer application 113 and the emergency call automatic transmission application 114.

  When the buzzer application 113 receives the buzzer stop event notification, the buzzer application 113 stops the output of the buzzer sound and the vibration of the vibrator, and ends the display of the sound animation screen (S104). Further, upon receiving the buzzer stop event notification, the emergency call automatic call application 114 ends the screen display related to the emergency call automatic call application 114 (S105).

  Next, another example in the second embodiment will be described.

  In the above-described second embodiment, the preceding application 113 has been described as an example in which the display priority of the application 113 is lowered (for example, S21 in FIG. 4). For example, the preceding application 113 may notify the priority display setting so as to increase the display priority of the additional service application 114 without lowering the display priority of the own application 113. Even in this case, the display priority of the additional service application 114 is higher than that of the preceding application 113, and information regarding the additional service application 114 can be displayed with priority over the preceding application 113. The preceding application 113 only needs to display information related to the additional service application 114 in preference to the preceding application 113 by changing the display priority.

  Further, in the above-described second embodiment, it has been described that the determination as to whether or not the service control is allowed and the display priority control are performed on the preceding application 113 side (for example, S20 in FIG. 4). For example, the priority service activation agent 116 may determine whether service control is permissible and display priority control. In this case, when the priority service activation agent 116 receives the priority display application activation notification (S18), the priority service activation agent 116 performs the determination and the change of the display priority. To the unit 115. Even in this case, instead of the display priority reduction setting, the display priority increase setting for the additional service application 114 may be used.

  As described above, the display priority when displaying information related to the preceding application 113 and the display priority when displaying information related to the additional service application 114 are the same. In such a case, in the second embodiment, when the additional service application program 114 is executed after the preceding application program 113 is executed, the display priority for the preceding application 113 or the additional service application 114 is changed. Like to do.

  By changing the display priority, for example, even when the additional service application 114 is executed after the preceding application 113 is executed, the information related to the additional service application 114 can be displayed with priority over the preceding application 113. Become. Therefore, the information processing apparatus 100 can display information regarding the application added by downloading.

  Then, since the information about the downloaded additional service application 114 is displayed on the display unit 170, the situation where the additional service is not displayed even if downloaded is eliminated, and the information processing apparatus 100 sufficiently supports the additional service. It will be what.

  Further, for example, every time the additional service application 114 is downloaded in the information processing apparatus 100, the display priority of the additional service application 114 and the preceding application 113 is not rewritten by the OS layer 112 (or application control unit 115). In the second embodiment, the priority service activation agent 116 notifies the preceding application 113 of the priority service activation notification, and the preceding application 113 instructs to change the display priority. Therefore, the OS layer 112 itself is not replaced, and the display priority of either of the two applications 113 and 114 is not rewritten. Thereby, for example, the convenience for the user can be improved without the terminal provider exchanging the OS layer 112.

  In the second embodiment, in the preceding application 113, it is determined whether or not the additional service application 114 can perform service control (for example, S20 in FIG. 4). Thereby, for example, when the additional service application 114 added by download is an illegal additional service application, it can be prevented from being displayed on the display unit 170.

  Furthermore, in the second embodiment, an example has been described in which processing is performed on the assumption that the display priority of the preceding application 113 and the additional service application 114 is the same. For example, the application control unit 115 may check whether the display priorities of the two applications 113 and 114 are the same. For example, in FIG. 4, when the application control unit 115 notifies the activation of the preceding application 113 (S11), the display priority of the preceding application 113 is confirmed. Further, the application control unit 115 receives the priority display setting (S17) and confirms the display priority of the additional service application 114. If the display priority of the two applications 113 and 114 is the same, the application control unit 115 notifies the priority display application activation notification (S18), and if not, the application control unit 115 may not notify the notification.

[Other embodiments]
Next, other embodiments will be described. FIG. 12 is a diagram illustrating a configuration example of the information processing apparatus 100. The information processing apparatus 100 illustrated in FIG. 12 further includes an external IF (Interface) 180. The external IF 180 can be connected to a public network by wire, for example, and can download the additional service application program 114 via the public network. For example, the information processing apparatus 100 illustrated in FIG. 2 can download the additional service application program 114 wirelessly, and the information processing apparatus 100 illustrated in FIG. 12 can download the additional service application program 114 by wire.

  FIG. 13 is a diagram illustrating a configuration example of the information processing apparatus 100. The information processing apparatus 100 illustrated in FIG. 13 can download the additional service application program 114 by both wired and wireless.

Instead of the CPU 110, a device that operates as a controller (or control unit) such as an MPU (Micro Processing Unit) or an FPGA (Field Programmable Gate Array) may be provided.

  In the above-described embodiment, the example where both the additional service application and the preceding application belong to “system error” and “telephone” in the display layer shown in FIG. 3 has been described. For example, even when two applications belong to any one of “system overlay”, “toast”, and “normal application” for the display layer shown in FIG. 3, the above-described processing can be performed.
