To do.

Next, a specific example of the shortcut processing in the example of FIG. 27 will be described with reference to FIGS. 29 to 38.

First, when both the audio player and the instant messenger in the infrastructure mode of WLAN are activated and the communication function by the instant messenger and the playback function by the audio player are executed at the same time, the shortcut to the communication function by the instant messenger is executed. A specific example will be described (arrow A in FIG. 27).

When the INFO button 11 is pressed when the communication status in the communication function by instant messenger is, for example, an event in the logged-in communication tool is occurring, as shown in FIG. 29A, for each e-mail service. E-mail information 811 indicating the number of unread e-mails, etc., and for each unprocessed event (for example, chat), an icon representing a communication tool, an icon indicating the content of the event, the ID of the communication partner, and the time when the event occurred. Communication INFO panel 801-1A for IM including event information 812 such as is displayed.

In the case of this example, the information about the newly generated event of the event information 812 (in the example of FIG. 29A, the information at the top of the event information 812) has a flag icon indicating that the event has newly occurred. Is displayed.

When an event occurs, as shown in FIG. 30, a flag icon indicating that the event has occurred is displayed in the communication use application status display area 204 of the constant display panel 101, so that the user can use that icon. Is displayed on the constant display panel 101, and if the INFO button 11 is pressed, the communication INFO panel 801-1A for IM shown in FIG. 29A can be displayed, so check the newly generated event. Can be done.

Also, when the INFO button 11 is pressed in the communication state where no new event has occurred (that is, when the flag icon is not displayed on the constant display panel 101), when there is an unprocessed event, , Event information 812 for outstanding events is displayed, as shown in Figure 29B, and when there are no outstanding events, message 813 is displayed to the effect that no events exist, as shown in Figure 29C. To.

When the INFO button 11 is pressed in this way, the communication INFO panel 801-1A for IM according to the communication status is displayed, but at the same time, the input from a predetermined input device such as the 4-way key 26 is displayed. It is assigned to the communication function by the instant messenger, and the instant messenger is controlled in response to the input from the 4-way key 26, for example.

For example, by operating the four-way key 26, information about the event at the top of the event information 812 in FIG. 29A can be selected and determined, GUI814 as shown in FIG. 31A is displayed, and the GUI814 is responded to. Events can be processed by entering a message and confirming the input. After that processing, for example, as shown in FIG. 31B, the contact list 815 in the communication tool is displayed.

In this way, by operating the INFO button 11, it is possible to shortcut to the communication function in the infrastructure mode.

Next, a specific example will be described when a shortcut to the communication function in the ad hoc mode is performed when, for example, music streaming in the ad hoc mode of the WLAN is activated and the communication function and the playback function in the ad hoc mode are executed at the same time (. Arrow C in Figure 27).

When the INFO button 11 is pressed when the communication status in the communication function in the ad hoc mode is the state in which the event of receiving the registration request is occurring, a message indicating that the registration request has been made, as shown in FIG. 32A, is displayed. The communication INFO panel 801-1B for ad hoc mode is displayed, which includes a 821 and a button 822 to access the event.

When an event occurs, as shown in FIG. 33, an icon indicating that an event in ad hoc mode communication has occurred is displayed in the communication use application status display area 204 of the constant display panel 101, so that the user can use it. , When the icon is always displayed on the display panel 101, if the INFO button 11 is pressed, the information corresponding to the event that has occurred can be confirmed.

Also, when the INFO button 11 is pressed when the communication status is such that an event that a file is being transferred from another information communication terminal 1 is occurring, the file is being transferred as shown in FIG. 32B. A message 831 to that effect and a communication INFO panel 801-1B for ad hoc mode containing a button 832 to access the event are displayed.

Further, when the INFO button 11 is pressed while the communication state is the state in which the event that the music from the other information communication terminal 1 is being streamed is occurring, that fact is shown in FIG. 32C. The communication INFO panel 801-1B for ad hoc mode is displayed, which includes streaming information 841 indicating. In the streaming information 841, a face icon (FIG. 23) registered as registration information of the other information communication terminal 1 of the streaming source is displayed.

In addition, when the INFO button 11 is pressed when the communication state is in the state where the event that the other information communication terminal 1 is streaming and playing the music provided by itself is occurring, FIG. 32D shows. As a result, the communication INFO panel 801-1B for ad hoc mode containing the streaming information 851 indicating that fact is displayed. In the streaming information 851, a face icon registered as registration information (own registration information) of the information communication terminal 1 of the streaming source is displayed.

If the INFO button 11 is pressed in the communication state that no event has occurred, the communication INFO panel 801-1B for ad hoc mode including the carry-on information 861 is displayed as shown in FIG. 32E. .. In the case of this example, the carry-on information 861 contains information published in ad hoc mode.

When the button 11 is pressed in this way, the communication INFO panel 801-1B for ad hoc mode according to the communication status is displayed, but at the same time, the input from a predetermined input device such as the 4-way key 26 is displayed. It is assigned to the communication function in the ad hoc mode, and the communication in the ad hoc mode is controlled in response to the input from the four-way key 26, for example.

For example, when the button 822 of FIG. 32A is operated, as shown in FIG. 34, a GUI 823 for registering the other party requesting registration is displayed, and the registration process can be performed using the GUI 823.

In this way, by operating the INFO button 11, it is possible to shortcut to the communication function in the ad hoc mode.

Next, a specific example of a shortcut to the playback function will be described (arrows B, D, F in FIG. 27).

In the case of this example, when the communication INFO panel 801 is displayed, the operation input from a predetermined input device is assigned to the communication function, the communication function is shortcut, and then the INFO panel 11 is further pressed, for example, FIG. 35. The playback INFO panel 801-2 shown in is displayed.

The reproduction INFO panel 801-2 is configured to include, for example, information according to the reproduction state such as a title name of music data, an artist name, an album name, or a thumbnail image of a jacket of an album or the like. Note that this information is basically the same as the information displayed on the music data playback display screen 512 shown in FIG.

Even when the playback function is not performed, the playback INFO panel 801-2 is displayed in response to the operation of the INFO button 11. In this case, the contents of the INFO panel 801-2 are as shown in FIG. It will be blank.

Also, even if the music being played is stored locally (for example, even if it is stored in the large-capacity flash memory 154 of FIG. 11), it is being streamed. However, basically, the same playback INFO panel 801-2 is displayed, but the music being played is stored locally, or it receives streaming from another information communication terminal 1. You can also display the playback INFO panel 801-2 to show what you have.

For example, the communication INFO panel 801-1B for ad hoc mode (the same communication INFO panel 801 as FIG. 32C) including the streaming information 841 indicating that the music provided from the other information communication terminal 1 is being streamed, as shown in FIG. 37A. When the INFO button 11 is further pressed while -1B) is displayed, it is assumed that the playback state is the streaming playback state, and as shown in FIG. 37B, the upper half of the playback INFO panel 801-2. It is possible to display the playback INFO panel 801-2 in which the area 851 is the color represented by the user color information (FIG. 23) registered as the registration information of the information communication terminal 1 of the streaming source. In the case of this example, the area 852 is the color represented by the user color information (FIG. 23).

Also, if you are playing something that is stored locally, it is assumed that the playback state is that you are playing a song that is stored locally, and the user color information that is registered as your own registration information. The playback INFO panel 801-2 with the color represented by (Fig. 23) can be displayed.

For ad hoc mode including when the music is provided to another information communication terminal 1 for streaming playback, that is, the streaming information 851 indicating that the music provided by oneself is being streamed as shown in FIG. 38A. When the INFO button 11 is pressed further while the communication INFO panel 801-1B (same communication INFO panel 801-1B as in Fig. 32D) is displayed, it is not information about one's own playback, but as shown in Fig. 38B. It is also possible to display the playback INFO panel 801-2 showing the playback information of the streaming destination.

When the INFO button 11 is pressed in this way, the playback INFO panel 801-2 according to the playback status is displayed, but at the same time, the input from a predetermined input device such as the 4-way key 26 is displayed in the playback function. It is assigned, and the reproduction process is controlled according to the input from, for example, the four-way key 26.

In this way, by operating the INFO button 11, it is possible to shortcut to the playback function.

Next, the operation of the application manager (FIG. 28) when executing the shortcut process will be described with reference to the flowchart of FIG. 39. Note that this shortcut process is performed when a plurality of predetermined functions are executed at the same time, and in this example, it is assumed that the wireless communication function and the playback function are executed at the same time.

In step S1, the shortcut operation input acquisition unit 901 waits until the operation input to the INFO button 11 is received by the input module 150 (that is, until the INFO button 11 is pressed), and when the INFO button 11 is pressed. , Notify the shortcut control unit 902 to that effect, and proceed to step S2.

In step S2, the shortcut control unit 902 determines whether or not the wireless communication function of the information communication terminal 1 is enabled, and if it is determined that the wireless communication function is enabled, the process proceeds to step S3.

Specifically, the shortcut control unit 902 determines, for example, whether or not the ON operation of the WLAN ON / OFF switch 30 is accepted by the input module 150, and if it is determined that the operation is accepted, step S3. Proceed to.

In step S3, the shortcut control unit 902 detects whether the WLAN application is in infrastructure mode or ad hoc mode, and in step S4, acquires the communication status in that mode.

Specifically, at this time, the communication status acquisition unit 903 detects and detects an application (for example, a communication application, a streaming application, or an instant messenger) that is currently running and realizes a wireless communication function. Access the application, acquire the communication status of the communication function being executed (for example, that a predetermined event has occurred), and supply it to the shortcut control unit 902.

The shortcut control unit 902 supplies the communication status of the executed communication function supplied from the communication status acquisition unit 903 to the INFO panel generation unit 905.

In step S5, the IMFO panel generation unit 905 generates the communication IMFO panel 801-1 according to the communication state of the communication function being executed, which is supplied from the shortcut control unit 902, and supplies the communication IMFO panel 801-1 to the display module 142. As a result, the display module 142 displays the communication INFO panel 801-1 supplied from the INFO panel generation unit 905 on the display unit 21 (arrows A, C, E in FIG. 27).

In step S6, the shortcut control unit 902 controls the operation input allocation unit 906 to allocate the operation input from the predetermined input device received by the input module 150 to the communication function currently being executed. That is, the operation input received by the input module 150 is supplied to the application executing the function. If the communication function has already been executed and the operation input from the predetermined input device is assigned to the communication function, the operation input from the predetermined input device is continuously assigned to the communication function.

By supplying the operation input to the application that realizes the communication function in this way, the user can use the communication function that is currently being executed by operating the input device.

Next, in step S7, the shortcut operation input acquisition unit 901 determines whether or not the operation input to the BACK button 24 is accepted by the input module 150 (that is, the BACK button 24 is operated), and is operated. If not, the process proceeds to step S8, and it is determined whether or not the INFO button 11 is further pressed.

When it is determined in step S8 that the INFO button 11 has not been pressed further, the process returns to step S7, and the subsequent processing is performed in the same manner.

When it is determined in step S2 that the wireless communication function of the information communication terminal 1 is not enabled, or when it is determined in step S8 that the INFO button 11 is further pressed, the process proceeds to step S9, and the shortcut control unit The 902 acquires the playback state of the currently executed playback function.

Specifically, at this time, the playback state acquisition unit 904 detects an application (for example, a streaming application or an audio player) that realizes the playback function that is currently started, and accesses and plays back the detected application. Acquires the state (for example, the locally stored music such as the name of the music being played is being played, and streaming playback is being performed), and supplies the status to the shortcut control unit 902.

The shortcut control unit 902 notifies the INFO panel generation unit 905 of the reproduction state of the execution function supplied from the reproduction state acquisition unit 904.

In step S10, the IMFO panel generation unit 905 generates a playback IMFO panel 801-2 according to the playback state of the playback function being executed, which is supplied from the shortcut control unit 902, and supplies the playback IMFO panel 801-2 to the display module 142. As a result, the display module 142 displays the reproduced INFO panel 801-2 supplied from the INFO panel generation unit 905 on the display unit 21 (arrows B and D in FIG. 27). The display processing of the INFO panel 801-1C in the example of FIG. 27 is omitted.

In step S11, the shortcut control unit 902 controls the operation input allocation unit 906 to allocate the operation input from the predetermined input device received by the input module 150 to the playback function currently being executed. That is, the operation input received by the input module 150 is supplied to the application executing the reproduction function.

By supplying the operation input to the application that realizes the playback function in this way, the user can use the playback function by operating the input device.

In step S12, the shortcut operation input acquisition unit 901 determines whether or not the INFO button 11 or the BACK button 24 has been operated, and waits until any of the buttons is operated.

When it is determined that the BACK button 24 has been operated in step S7, or when it is determined that the INFO button 11 or the BACK button 24 has been operated in step S12, the process proceeds to step S13, and the shortcut control unit 902 generates an INFO panel. Control the display module 142 through section 905 to erase the INFO panel 801 displayed in step S5 or step S10 (ie, return to the hidden state of the INFO panel 801) (arrows H, I, in FIG. 27). J, or arrow G).

The shortcut control unit 902 also controls the operation input allocation unit 906 to release the allocation (step S6 or step S11) of the communication function or the reproduction function of the operation input from the input device received by the input module 150. As a result, for example, the operation input is assigned to the operation process on the HOME screen 451. Therefore, the user can operate the HOME screen 451 by operating the input device.

After returning to the hidden state of the INFO panel 801 in step S13, the process returns to step S1 and the subsequent processing is performed in the same manner.

As described above, the shortcut process is executed.

In the above description, the case where the wireless communication function and the playback function are executed at the same time and the shortcut is made to either the wireless communication function or the playback function has been described as an example, but the present invention can be applied to other functions as well. ..

Next, another example of assigning operation input will be described.

When the information communication terminal 1 is used as a telephone, that is, when the communication application is started and the IP telephone function is executed, the operation input from the music key 35 is assigned to the volume of the IP telephone. It is assigned to the adjustment function.

When the user uses an IP telephone with the information communication terminal 1, as shown in FIG. 10, the user sets the information communication terminal 1 so that the positions of the speaker 28 and the microphone 29 of the information communication terminal 1 correspond to the positions of the ears and the mouth. Will have. That is, at this time, the positional relationship between the finger of the user's left hand and each input device of the information communication terminal 1 is as shown in FIG. 40. Therefore, the position of the music key 35 on the side surface in the longitudinal direction of the main body is The position is easy to operate with the thumb of the left hand. When held by the right hand, the position is easy to operate with the index finger, middle finger, etc. of the right hand, although the illustration is omitted.

Therefore, when using an IP phone on the information communication terminal 1, the user can easily adjust the volume of the call by assigning the operation input from the music key 35 to the volume adjustment function of the IP phone. become.

It is possible to provide a separate volume control button when using an IP phone, but for example, if there is no space to newly provide such a button, the music key 35 can also be used as a volume control button in this way. If set to, the volume can be adjusted without providing a separate button, and if the music key 35, which is in a position that is easy to operate when using an IP phone, is used for the volume adjustment, information communication is performed during the volume adjustment. You can easily adjust the volume without changing the terminal 1.

The IP telephone service is a relatively new service, and its infrastructure is not yet fully equipped at present. Therefore, the volume of the call changes depending on the position where the user's information communication terminal 1 is used, and it is often difficult to hear the call. When the device of the other party of the call is a personal computer, the volume of the call may be reduced depending on the volume setting of the personal computer.

That is, since it is expected that the volume adjustment will be performed frequently when using the IP phone, it is possible to give the information communication terminal 1 a function that can easily adjust the volume when using the IP phone. It is especially useful as an IP phone terminal.

FIG. 41 shows a functional configuration example of the application manager of the application processor 131 when executing the process of allocating the input from the music key 35 to the volume adjustment process of the call during the IP phone when the IP telephone function is executed. Shown.

The IP telephone function detection unit 951 is used, for example, when the communication application (Communication) 461 on the HOME screen 451 in FIG. 13 is selected and determined and the execution of the IP telephone function is started, or when the execution of the IP telephone function is completed. Notify the operation input allocation unit 952 to that effect.

When the operation input allocation unit 952 receives a notification from the IP telephone function detection unit 951 that the execution of the IP telephone function has started, the operation input allocation unit 952 allocates the input from the music key 35 to the volume adjustment function in the IP telephone function.

The operation input allocation unit 952 also receives a notification from the IP telephone function detection unit 951 that the execution of the IP telephone function is completed after assigning the operation input from the music key 35 to the volume adjustment function in the IP telephone function. And, the IP telephone function of the input from the music key 35 is unassigned (that is, the input from the music key 35 is assigned to the function before the IP telephone function is assigned).

The series of processes described above can be executed by software or by using hardware built in to execute the series of processes described above. The software is, for example, a general-purpose computer in which the programs constituting the software can execute various functions by installing a computer embedded in the dedicated hardware or various programs. It is installed from a recording medium on a personal computer or the like.

As shown in FIG. 11, this recording medium is a magnetic disk (including a flexible disk) or an optical disk (CD-ROM (CD-ROM)) on which a program is recorded, which is distributed to provide a program to a user separately from a computer. Compact Disk-Read Only Memory), DVD (including Digital Versatile Disk)), optical magnetic disk (including MD (Mini-Disk) (trademark)), removable media 172 consisting of semiconductor memory, etc.

Further, in the present specification, the steps for describing a program recorded on a recording medium are not necessarily processed in chronological order, but also in parallel or in parallel or not necessarily in chronological order. It also includes processes that are executed individually.
