The content recording unit 117 records content processed by applications that can be activated from the menu display apparatus 100 and content information C. The content recording unit 117 records content and content information C by associating with applications. The communication unit 119 transmits/receives data to/from other information processing apparatuses such as a service provider via a communication network N.

An application is software having a GUI to communicate with the user, having a function to perform the work desired by the user to perform with the menu display apparatus 100, and which can be activated from the menu display apparatus 100. Hereinafter, software like an accessory having a GUI such as a widget is also called an application. A so-called service that executes a portion of application functions, but does not have a GUI is distinguished from the applications. A service is a program or the like executed in the background of a menu display program even when, for example, a mailer having a GUI is not executed to perform a mail transmitting/receiving function. Content means entity data such as still images, video, voice, text, Web pages, mail, and games. Content information C means information accompanying entity data of content such as the identifier, name, category, and icon of content.

[2. Menu Display Method]

FIG. 2 is a flow chart showing the processing order of the menu display method.

As shown in FIG. 2, the menu execution unit 103 registers applications that can be activated by the menu display apparatus 100 with a menu (step S101). Applications are registered based on preset values when a menu display program is installed or registered by a user's operation in launcher mode OM5. Then, registration information of applications is written into the holding unit 107.

The menu execution unit 103 sets setting conditions for the area A for each of the registered applications (S103). Setting conditions for the area A includes the arrangement, size, and rotation angle of the area A in the menu. Setting conditions for the area A are set based on preset values when the area A is registered and adjusted by the user if necessary before being written into the holding unit 107. After area A registration, setting conditions for the area A are also written into the holding unit 107 after being changed by the user if necessary in area editing mode OM4.

The application execution unit 105 provides display data of the content information C representing content to be displayed in the menu/sub-menus through execution of each application (S105). Display data of the content information C is created based on the content information C recorded in the content recording unit 117 and/or based on a user's operation and written into the holding unit 107 for each application. Display data of the content information C is written periodically or non-periodically during execution of an application (and a service).

The application execution unit 105 sets content to be displayed in the menu/sub-menus through execution of each application. Content to be displayed in the menu/sub-menus is set based on the usage date/time of content, update date/time, usage frequency, and information specified by the user concerning content. Content to be displayed in the menu/sub-menus is set as content executed by an application immediately before, content whose update is detected immediately before, content whose usage frequency is high, or content specified by the user immediately before via an application.

The application execution unit 105 sets for each application display data of the content information C representing content to be displayed in the menu/sub-menus through execution of each application. Display data of the content information C includes a list of the content information C, images of the content information C, and the arrangement, size, rotation angle and the like of the content information C in the area A. The type, format and the like of display data of the content information C are preset between the application and the menu execution unit 103. That is, display data of the content information C is provided to the menu execution unit 103 by the application execution unit 105 through execution of an application according to predetermined rules defined for executing the menu display method.

The menu execution unit 103 causes the display unit 115 to display the menu via the display controller 113 according to registration information of the application, setting conditions for the area A corresponding to the application, and display data of the content information C (S107). The menu execution unit 103 reads display data of an application periodically or non-periodically from the holding unit 107 during execution of the menu such as when the menu is activated or the application terminates. In the menu, display data of the content information C representing content to be displayed in the menu is displayed in the area A set for each registered application.

If the state of each application is updated through execution of the application, the application execution unit 105 notifies the menu execution unit 103 of the state update (S109, S111). The state update of an application can be notified if a service is being executed even though the application execution unit 105 is not executing the application.

The state update of an application is notified when, for example, content is used or updated or an operation is performed on content so that it becomes necessary to change the display of the corresponding area A. In accordance with the state update of an application, the application execution unit 105 writes display data necessary to update the display of the corresponding area A into the holding unit 107. It is desirable that the application execution unit 105 make a notification of the state update after identifying the application and content information C. Then, the menu execution unit 103 reads the updated display data from the holding unit 107 to cause the display unit 115 to display the updated menu via the display controller 113 (S113).

The notification of the state update is used for different uses from application to application. For example, the notification of the state update is used to make a notification that recommendation information is acquired from a service provider registered for each application via the communication unit 119. A music player, video player, or photo player uses the notification of the state update to make a notification of addition/deletion of content to/from a specific recording location of the menu display apparatus 100 such as addition/deletion of content to/from the menu display apparatus 100. A Web browser uses the notification of the state update to make a notification of the update of an RSS channel registered by the user. A mailer uses the notification of the state update to make a notification of new mail. A scheduler uses the notification of the state update to make a notification of the arrival of the time point set by the user.

If the area A in the menu is selected, the menu execution unit 103 causes the display unit 115 to display, via the display controller 113, the sub-menu of the application corresponding to the selected area A (S115, S117). The menu execution unit 103 causes the display unit 115 to display the sub-menu via the display controller 113 according to display data of the content information C representing content (including sub-content) to be displayed in the sub-menu.

If content (including sub-content) is selected from the sub-menu, the menu execution unit 103 notifies the application execution unit 105 of content execution instructions (S119, S121). Execution instructions are notified together with parameters for application activation if necessary. The application execution unit 105 executes the application that processes the selected content (S123). The application execution unit 105 reads the selected content from the content recording unit 117 to process the content through execution of the application.

[3. Operation Mode]

FIG. 3 is a diagram showing transitions of the operation mode of the menu display apparatus 100. As shown in FIG. 3, the menu display apparatus 100 has operation modes of an overall view mode OM1, an area view mode OM2, an application execution mode OM3, the area editing mode OM4, and the launcher mode OM5.

The overall view mode OM1 is a mode in which a menu of a plurality of applications is displayed by using the area A provided for each application. The area view mode OM2 is a mode in which the sub-menu of an application is displayed. The application execution mode OM3 is a mode in which an application is executed. The area editing mode OM4 is a mode in which the layout of the area A is edited in the menu. The launcher mode OM5 is a mode in which an application is activated or an application is registered.

In accordance with a selection operation of the area A, the operation mode is switched from the overall view mode OM1 to the area view mode OM2 (T12). In accordance with a mode selection operation, the operation mode is switched from the area view mode OM2 to the overall view mode OM1 (T21). In accordance with content execution instructions in the sub-menu, the operation mode is switched from the area view mode OM2 to the application execution mode OM3 (T23). In accordance with a mode selection operation in an execution screen of an application, the operation mode is switched from the application execution mode OM3 to the overall view mode OM1 (T31).

In accordance with a mode selection operation, the operation mode is switched between the overall view mode OM1 and the area editing mode OM4 (T14, T41) and the operation mode is switched between the overall view mode OM1 and the launcher mode OM5 (T15, T51). Also, in accordance with an activation operation of an application, the operation mode is switched from the launcher mode OM5 to the application execution mode OM3 (T53).

FIG. 4 is a diagram showing transitions of the operation mode from the overall view mode OM1 through area view mode OM2 to the application execution mode OM3. FIG. 5 is a diagram showing focus movement between the areas A.

In FIG. 4, the menu display apparatus 100, which is a folding PDA, is displayed. The menu display apparatus 100 is provided with a frame F that partitions the display screen into an upper region and a lower region to realize a folding mechanism. Hereinafter, though the display screen of the menu display apparatus 100 is partitioned into the upper region and the lower region, a case where the display screen is composed of a single display region is also described in the same manner.

[3-1. Overall View Mode OM1]

In FIG. 4A, a display example of the menu in overall view mode OM1 is shown. In the upper region and lower region, along with the area A for each registered application, display data of the content information C representing content to be displayed in the menu is displayed in each area A.

The menu execution unit 103 causes the display unit 115 to display the menu via the display controller 113 according to registration information of an application, setting conditions for the area A corresponding to the application, and display data of the content information C to be displayed in the menu.

In the example shown in FIG. 4A, areas A1, A2, A3, A4, A5, and A6 are provided for each of the applications such as the clock, mail, photo, movie, music, and Web update respectively in the menu. While the area A is provided as a rectangular region, the areas A may be provided as a region having a shape other than a rectangle. Starting point moving buttons “PREY”, “NEXT” B1, B2 to move the focus between the areas A are displayed at the bottom of the display screen. Launcher buttons B3, B4 to display a launcher L in each of the upper region and lower region are displayed at the left end and right end of the display screen respectively.

In the area A1 of the clock, the content information C of clock content is displayed. In the area A2 of the mail, the mail reception date is displayed along with the content information C of mail content received immediately before. In the area A3 of the photo, the content information C (thumbnail images) of photo content is displayed. In the area A4 of the movie, the content information C (screen shot images) of movie content played back immediately before and the content information C of related content are displayed. In the area A5 of music, the content information C (album image) of music content played back immediately before. In the area A6 of the Web update, page update dates are displayed along with the content information C (screen shot images of Web pages) of Web content updated immediately before.

The name of the application corresponding to the area A is displayed in each area A and depending on the application, the name of content is displayed. In the menu, the area A4 of the movie indicated by a thick broken line is focused.

The area A is displayed in a predetermined layout in a menu region according to setting conditions including the arrangement of the area A, size, rotation angle, application name, and identifier. The menu region is a virtual plane where the area A of an application registered with the menu is laid out and a portion thereof is displayed on the display screen. The arrangement of the area A is defined by setting the upper left corner of the area A as a reference point, the size thereof is defined as relative coordinates from the reference point to the lower right corner of the area A, and the rotation angle thereof is defined as an angle with the reference point set as a rotation center.

Content information C is displayed in a predetermined layout in each area A according to display data composed of a list of the content information C, an image of the content information C, and the arrangement, size, rotation angle, content name, and identifier of the content information C in each area A. Like the area A, the arrangement, size, and rotation angle of the content information C is defined for display data of the content information C.

While the areas A are not arranged by overlapping with the other area A in the example shown in FIG. 4A, the area A may be arranged by overlapping with the other area A. In such a case, the display controller 113 controls the display of the areas A in such a way that the area A with an increasing priority is displayed so as to come to the top on the display screen according to the order of priorities set for each area A. It is desirable that the display controller 113 control the display of the area A so that the focused area A is displayed on top of the other areas A on the display screen.

The menu region can be scrollably displayed vertically, horizontally, or in a slanting direction with respect to the display screen and can also be rotatably displayed around the center of the menu region. If a drag operation is performed by specifying a region other than the area A in the menu, the menu region is scrolled and displayed by being linked to the drag operation. The drag operation is an operation in which the finger O in contact with the display screen is moved to a predetermined position on the display screen. If one of the focus moving buttons “PREV”, “NEXT” B1, B2 is operated, the menu region is rotated in accordance with the focus movement and displayed.

When the menu region is scrolled and displayed, the menu execution unit 103 calculates the layout of the area A on the display screen after scrolling and causes the display unit 115 to display the menu region after scrolling via the display controller 113. When the menu region is scrolled and displayed, the menu execution unit 103 calculates the layout of the area A on the display screen after scrolling by considering the scroll amount of the menu. A region of the menu region that extends beyond the display screen is not displayed.

FIG. 4B shows a state after the focus is moved from the state shown in FIG. 4A to the area A5 of music. The focus order is set to each area A in accordance with the arrangement of the area A in the menu region. The focus is moved to the area A in the next or previous focus order of the focused area A in accordance with the operation of the “PREV” or “NEXT” button B1, B2 in the menu.

The menu execution unit 103 calculates the layout of the area A and the content information C on the display screen by calculating a predetermined rotation angle from the rotation angle of the area A5 of music and performing coordinate conversion processing. Then, based on a processing result, the display controller 113 controls the display of the content information C in the area A for content to be displayed in the menu.

When the menu region is rotated and displayed, the menu execution unit 103 calculates a layout of the area A and the content information C on the display screen after the rotation and causes the display unit 115 to display the menu region after the rotation via the display controller 113. Display data of the content information C is set based on a state in which the menu region is not rotated. Thus, if the menu region is rotated and displayed, the menu execution unit 103 calculates the layout of the content information C on the display screen after the rotation by considering the rotation amount of the menu region for display data of the content information C.

In the example shown in FIG. 5, the focus order is set in a spiral fashion with the center of the menu region set as a reference. The focus order is set clockwise along a spiral with the area A arranged in the center of the spiral set as a starting point. In this case, the menu region is divided into, for example, 3×3 grid-like subregions (i, j) and each area A is allocated to the subregion in accordance with the center position (marked by  in FIG. 5) of the area A. The division number of subregions and the division shape are appropriately set in accordance with the number of areas A and the shape thereof.

As shown in FIG. 5, the upper left subregion and the lower right subregion are defined as a subregion (1, 1) and a subregion (3, 3), respectively. The areas A1, A2, A3, A4, A5, and A6 of the clock, mail, photo, movie, music, and Web update are allocated to subregions (2, 2), (1, 3), (1, 2), (1, 1), (3, 1), and (3, 3), respectively. The focus order is set in the order of the area A1 of clock, the area A2 of mail, the area A3 of photo, the area A4 of movie, the area A5 of music, and the area A6 of Web update clockwise in a spiral fashion using the subregion (2, 2) as a reference. If a plurality of areas A is allocated to the same subregion, the focus order of the areas A is set so that the focus order of the area A arranged in a position closer to the setting direction of the focus order is earlier.

In the state shown in FIG. 4B, the menu region rotates clockwise after the “NEXT” button B2 being operated in the state shown in FIG. 4A and the area A5 of music having the next focus order after the area A4 of movie is focused. The rotation angle of the menu region is adjusted so that the rotation angle of the area A5 of music becomes 0°. Accordingly, visibility of the focused area A5 can be improved.

The application execution unit 105 performs playback processing of sub-content in accordance with the operation of operation buttons in the operation menu AM.

[3-4. Area Editing Mode OM4]

FIG. 6 is a diagram showing edit processing of the area A. If a region corresponding to the area A on the display screen of the menu is touched over a predetermined period by the finger O or the like, the operation mode is switched from the overall view mode OM1 to the area editing mode OM4 and now the area A is editable. If a region outside the area A is touched by the finger O or the like over a predetermined period in an editable state, the operation mode is switched from the area editing mode OM4 to the overall view mode OM1.

In the example shown in FIG. 6, the area A4 of movie indicated by a thick broken line becomes an area to be edited. Change marks M1, M2 for changing the size and the angle are displayed in predetermined positions of the area A. In area editing mode OM4, as shown below, the arrangement, size, and rotation angle of the area A can be changed.

If, as shown in FIG. 6A, the user specifies a region outside the change marks M1, M2 in the area A4 and performs a drag operation, the arrangement of the area A4 is changed. The area A4 is changed in arrangement and displayed by being linked to the drag operation of the area A4 and the arrangement thereof is changed in accordance with the position of an area A4′ after the drag operation.

If, as shown in FIG. 6B, the user specifies the size change mark M1 in the area A4 and performs a drag operation, the size of the area A4 is changed. The area A4 is changed in size and displayed by being linked to the drag operation of the size change mark M1 and the size thereof is changed in accordance with the position of the size change mark M1 after the drag operation. In the example shown in FIG. 6B, if the size change mark M1 at the lower right corner of the area A4 is moved by a drag operation, the size of the area A4 is changed to the size of an area A4′ in accordance with the position of the size change mark M1 after the movement while the upper left corner of the area A4 is fixed.

If, as shown in FIG. 6C, the user specifies the angle change mark M2 in the area A4 and performs a drag operation, the rotation angle of the area A4 is changed. The area A4 is changed in rotation angle and displayed by being linked to the drag operation of the angle change mark M2 and the rotation angle thereof is changed in accordance with the position of the angle change mark M2 after the drag operation. In the example shown in FIG. 6C, if the size change mark M2 at the upper right corner of the area A4 is moved by a drag operation, the rotation angle of the area A4 is changed to the rotation angle of an area A4′ in accordance with the position of the angle change mark M2 after the movement while the upper left corner of the area A4 is fixed.

The menu execution unit 103 changes setting conditions (the arrangement, size, and rotation angle) for the area A based on a drag operation of the area A to be edited or the change marks M1, M2. Though edit processing of the area A is also performed in a state in which the menu is scrolled or rotated, setting conditions for the area A are changed based on coordinates of the menu region. That is, setting conditions for the area A are changed after conversion of the position of the area A or the change marks M1, M2 after the drag operation on the display screen based on coordinates of the menu region. Then, changed setting conditions for the area A are held by the holding unit 107.

FIG. 7 is a diagram showing rearrangement processing of the area A. If the user instructs to rearrange the area A by a predetermined operation in area editing mode OM4, the area A is rearranged. In the rearrangement of the areas A, the areas A are rearranged in such a way that overlapping of the areas A is reduced.

In the example shown in FIG. 7A, the areas A1, A3 of clock and photo, the areas A2, A6 of mail and Web update, and the areas A4, A5 of movie and music are overlapped and visibility of the areas A2, A3, A4 displayed behind the areas A1, A5, A6 is reduced.

The menu execution unit 103 compares center positions (marked by , ◯ in FIG. 7) of the areas A and center positions (marked by X in FIG. 7) of sub-regions and changes setting conditions for the area A to rearrange the area A. Then, changed setting conditions are written into the holding unit 107. In this case, the menu region is divided into, for example, 3×3 grid-like subregions (i, j) and each area A is allocated to the center position of the corresponding subregion in accordance with the center position of the area A. The division number and the division shape of subregions are appropriately set in accordance with the number of areas A and the shape thereof.

As shown in FIG. 7A, the upper left subregion and the lower right subregion are defined as a subregion (1, 1) and a subregion (3, 3), respectively. The areas A1, A3 of clock and photo are arranged in the subregion (2, 2), the area A2 of mail is arranged in the subregion (2, 3), the area A6 of Web update is arranged in the subregion (3, 3), and the areas A4, A5 of movie and music are arranged in the subregion (2, 1). In the case of, for example, the areas A1, A3 of clock and photo, the center position of the area A1 of clock is closer to the subregion (2, 2) than the center position of the area A3 of photo. The center position of the other area A is not present in the subregion (1, 2) positioned to the left of the subregion (2, 2).

Thus, as shown in FIG. 7B, the center position of the area A1 of clock is rearranged to the center position of the subregion (2, 2) and the center position of the area A3 of photo is rearranged to the center position of the subregion (1, 2). Similarly, the center position of the area A2 of mail is rearranged to the center position of the subregion (1, 3), the center position of the area A4 of movie is rearranged to the center position of the subregion (1, 1), the center position of the area A5 of music is rearranged to the center position of the subregion (2, 1), and the center position of the area A6 of Web update is rearranged to the center position of the subregion (3, 3).

The menu execution unit 103 performs rearrangement processing of the areas A as described above, changes setting conditions (arrangement of the areas A) for the areas A, and writes changed setting conditions into the holding unit 107. Along with the rearrangement of the areas A, the size of the area A and/or the rotation angle thereof may be changed. Rearrangement processing of the area A may be performed in a state in which the menu region is not scrolled or rotated or in a state in which the menu region is scrolled or rotated.

[3-5. Launcher Mode OM5]

FIG. 8 is a diagram showing registration processing of an application. If a region corresponding to launcher buttons B3, B4 on the display screen of the menu is touched over a predetermined period by the finger O or the like, the operation mode is switched from the overall view mode OM1 to the launcher mode OM5 and applications can be registered. If a region outside the launcher L is touched by the finger O or the like over a predetermined period on the display screen in a state in which applications can be registered, the operation mode is switched from the launcher mode OM5 to the overall view mode OM1.

If the launcher button B3 or B4 at the left end and right end of the display screen is operated, the launcher L is displayed by overlapping with the menu in the upper region or the lower region. In the launcher L, icons I1 to I7, names and the like of applications that are not registered with the menu of applications that can be executed from the menu display apparatus 100 are displayed.

If a region corresponding to an icon I of an application on the display screen of the launcher L is touched over a predetermined period by the finger O or the like, the menu execution unit 103 switches the operation mode to the application execution mode OM3. Then, the application execution unit 105 activates the corresponding application. In the example shown in FIG. 8A, the icon I2 of scheduler is selected and thus, a scheduler is activated.

If the icon I of an application is specified and a drag and drop operation is performed from the region of the launcher L region to the menu region, the menu execution unit 103 updates registration information of the application. Also, the menu execution unit 103 adds the area A of the corresponding application to the menu in accordance with the drag and drop operation of the icon I. In the example shown in FIG. 8B, the drag and drop operation of the icon I2 of scheduler is performed and thus, the scheduler is registered with the menu. Then, as shown in FIG. 8C, an area A7 of the scheduler is added to the menu.

The arrangement of the added area A7 is set by using a drop position of the icon I2 as a reference and the size and rotation angle thereof are set as predetermined values. The area A7 becomes editable like in area editing mode and the change marks M1, M2 for changing the size and rotation angle are displayed in the area A7. Then, the arrangement, size, and rotation angle of the area A7 are changed in the same manner as in area editing mode OM4. When the edit processing of the area A7 is finished, the menu execution unit 103 writes setting conditions of the area A7 into the holding unit 107.
