Description

  The present invention relates to an information processing apparatus that displays information.

  Conventionally, in a display system, a GUI (Graphical User Interface) has been adopted as a user interface. In a display system that employs such a GUI, a plurality of options that can be selected by the user are displayed on the display. A command for the display system is assigned to each of the plurality of options. The user selects a desired option using the operation member. As a result, the command assigned to the option selected by the user is executed in the display system.

  Also, in recent display systems, there are many commands that can be executed by the user's selection due to the diversification of installed functions. For this reason, in recent display systems, a GUI is adopted that categorizes these commands into a hierarchical structure and accepts selection of one command from commands included in the options of any hierarchy of the hierarchical structure. (See, for example, Patent Documents 1 and 2).

JP 2007-281582 A JP 2008-191728 A

  A user of a display system that selects a command from the above hierarchical structure selects a desired command to be executed by the display system by selecting an option for each hierarchy in order from the highest hierarchy. .

  By the way, in such a display system, when the hierarchy to be displayed on the display (hierarchy to be selected as an option) is changed to a hierarchy lower than the upper hierarchy different from the upper hierarchy of the current hierarchy. Many operations are required. Specifically, first, the user performs an operation of switching the hierarchy to be displayed one by one from the current hierarchy to the upper hierarchy one by one, so that the hierarchy whose upper hierarchy can be changed is made the display target. In this state, an operation for changing the upper hierarchy is performed. Furthermore, an operation of switching the hierarchy to be displayed one by one to a lower hierarchy is performed, so that the target hierarchy is made the display target.

  As the number of necessary operations increases as described above, the user feels very complicated, and improvement is desired. For example, in a display system mounted on a vehicle, a user operates the display system while paying attention to the situation around the vehicle and other instruments of the vehicle during a relatively short period such as when the vehicle is waiting for a signal. A scene arises. For this reason, in the display system mounted in a vehicle, the technique which can reduce the frequency | count of a required operation was desired.

  The present invention has been made in view of the above problems, and provides a technique that can be selected by a simple operation in information having a hierarchical structure, mainly a technique that can reduce the number of operations for selecting different upper layers. The purpose is to do.

  One of the aspects for solving the above problem is that at least a first hierarchy option group included in the hierarchical structure and a second hierarchy option group corresponding to one of the first hierarchy options. Both are information processing apparatuses including a display control unit that is displayed on a display device in an operable state.

  According to the configuration according to the present application, it is possible to reduce the number of operations for selecting a different upper layer mainly by a technique that can be selected by a simple operation in information having a hierarchical structure.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

<First Embodiment>
In the first embodiment, a hierarchical structure display method and operation method when audio data to be reproduced by an information processing apparatus is selected will be described. Here, although an in-vehicle device is described as one of the embodiments as an information processing device, the configuration according to the present application is not limited to the in-vehicle device. For example, a portable mobile terminal (for example, a PND, a mobile phone, It can also be realized in a portable display device. The in-vehicle device according to the configuration of the present application is referred to as an AVN integrated device. Here, the AVN integrated device is an in-vehicle electronic device that integrally has an audio function, a visual function, and a navigation function.

(Hierarchical structure)
FIG. 1 is a diagram illustrating an example of a hierarchical structure of audio data. In the example shown in FIG. 1, the first layer is the top layer, and the lower the layer as the number increases.

  The elements of the first layer include “playlist”, “artist”, “album”, “music title”, and “genre”. Since the hierarchical structure starts with an element of the first layer as a starting point, the element of the first layer is referred to as a root in the first embodiment. By selecting the element of the first layer, the elements of the hierarchy below the second layer are determined, that is, the hierarchical structure is determined.

  For example, by selecting “playlist” as a route, the user can select music to be reproduced from music narrowed down by the playlist. In the first embodiment, the music indicates audio data. When “playlist” is selected as the root, the hierarchical structure is “playlist” → “playlist name list” → “music name list for each playlist”, and the hierarchy is three layers. The playlist is a collection of audio data selected by the user of the AVN integrated device, and each playlist is given a name by the user or automatically. The playlist name list is a list of names of all playlists included in the audio source of the AVN integrated device, and is arranged in, for example, alphabetical order or alphabetical order. The song name list for each playlist is a list of song names included in the playlist, and is arranged in the order set by the user.

For example, by selecting “artist” as the root, the user can narrow down the music by using the artist name and select the music to be played. When “Artist” is selected as the root, the hierarchical structure is “Artist” → “Artist name list” → “Album name list for each artist” → “Music name list for each album”. Become. The artist name is the name of a music player, singer, group, or the like. The artist name list is a list of all artist names in the source of the AVN integrated device, and is arranged in, for example, alphabetical order or alphabetical order. The album name list for each artist is a list of album names of a certain artist in the source of the AVN integrated device, and is arranged in, for example, alphabetical order or alphabetical order. The song name list for each album is a list of names of songs included in a certain album in the source of the AVN integrated device, and is arranged in the order recorded in the album.

  For example, by selecting “album” as a root, the user can select music to be played back by narrowing down music from the album name list using the album name as a clue. When “album” is selected as the root, the hierarchical structure is “album” → “album name list” → “music name list for each album”, and there are three layers. The album name list is a list of names of all albums in the source of the AVN integrated device, and is arranged in, for example, the alphabetical order or alphabetical order. The song name list for each album may be the same list as the “music name list for each album” which is an element of the fourth layer of the hierarchical structure with “artist” as the root.

  For example, the user can select a music to be played from the music name list by selecting “music name” as the root. When “song name” is selected as the root, the hierarchical structure is “song name” → “song name list”, and the hierarchy is two layers. The song name list is a list of names of all songs in the source of the AVN integrated device, and is arranged in, for example, alphabetical order or alphabetical order.

  For example, by selecting “genre” as the root, the user can select music to be played by narrowing down the genre from the list of genre names. When “genre” is selected as the root, “genre name” → “genre name list” → “artist name list by genre” → “album name list by artist” → “music list by album” It has a hierarchical structure, and the hierarchy is five layers. The genre name list is a list of genre names of songs in the source of the AVN integrated device, and is arranged in, for example, alphabetical order or alphabetical order. The artist name list for each genre is a list of names of artists classified into a certain genre, and is arranged, for example, in alphabetical order or alphabetical order. The album name list for each artist may be the same list as the “album name list for each artist” which is an element of the third layer of the hierarchical structure having “artist” as a root. The song name list for each album is the elements of the fourth layer of the hierarchical structure having “artist” as the root, “the song name list for each album”, and the third layer of the hierarchical structure having “album” as the root. It may be the same list as the element “music list for each album”.

(Screen transition example of playback music selection process)
2, 3, 4, 5, 6, 7, 8, 9, and 10, Apple's iPod (registered trademark) is used as an audio source, and the hierarchical structure of FIG. 1 is used. Among them, the music to be played is selected according to the hierarchical structure with “artist” as the root, that is, “artist” → “artist name list” → “album name list by artist” → “song name list by album” It is a figure which shows an example of the transition of the screen display of an AVN integrated machine in the case of being performed. It is assumed that the hierarchical structure of music in the iPod is the hierarchical structure shown in FIG. Hereinafter, when expressing as right and left, unless otherwise specified, the right and left are indicated on the screen.

  Here, iPod (registered trademark) is described as an example. However, the present invention is not limited to this, and any music playback device that can cooperate with an AVN integrated device may be used. In this case, the item “iPod (registered trademark)” is not displayed in the basic menu described below. Instead, a display that can identify the music playback device connected to the AVN integrated device is performed (for example, a device name, a trademark, etc. are displayed).

  The operations on the screen of the AVN integrated device, that is, the operation of the user's finger on the touch panel recognized by the AVN integrated device include, for example, push, release, scroll, flick, and slide. Push is an operation of pressing the touch panel at a predetermined pressure or more, and release is an operation of releasing a finger from the touch panel. By combining push and release, an operation for selecting an item displayed in the area including the released position is performed. Scrolling is an operation of moving a finger on a touch panel at a predetermined speed for a predetermined distance. For example, the scrolling is an operation of changing a screen or moving a display object in a certain display area. Although flicking is an operation of moving a finger on the touch panel in the same manner as scrolling, the moving distance is shorter than scrolling. The flick is, for example, an operation of changing the screen, moving a display object within a certain display area, or an operation of selecting an item from the touch position, like scrolling. The slide is an operation of moving the finger on the touch panel at a slower speed than the scroll while keeping the finger in contact with the slide, and is a drag and drop operation in combination with push and release.

  FIG. 2 is a diagram showing an example of a basic menu selection screen of the AVN integrated device. The basic menu selection screen is, for example, a top screen that is displayed when the AVN integrated device is started up, after the opening screen, or when the mode of the AVN integrated device is selected.

The basic menu selection screen SC1 shown in FIG. 2 includes a basic menu display area A1, a navigation display area A2, and a shortcut display area A3.
The basic menu display area A1 is an area for displaying items indicating basic functions of the AVN integrated device. Hereinafter, items indicating basic functions of the AVN integrated device are referred to as basic menus. A hierarchical structure as shown in FIG. 1 exists for each basic menu (hierarchical structure group). The navigation display area A2 is a navigation area in which, for example, the current position of the vehicle equipped with the AVN integrated device, the destination, the route from the current position to the destination, road traffic congestion information, and the like are displayed. The shortcut display area A3 is an area where icons of shortcut menus are displayed.

  In the first embodiment, the basic menu of the AVN integrated device includes “present location”, “destination”, “iPod (registered trademark)”, “vehicle”, “information / G”, “phone”, and “setting / "Edit" is included. “Current location” in the basic menu is an item for displaying the current position of the vehicle equipped with the AVN integrated device. When “Current location” is selected, the navigation display area A2 is displayed on the screen, and the navigation display area A2 is displayed. The current position of the vehicle on which the AVN integrated device is mounted is displayed. The basic menu selection screen SC1 is a setting in which the current position of the AVN integrated device is displayed in the navigation display area A2 by default, that is, a setting in which “current location” in the basic menu is selected. “Destination” in the basic menu is an item for setting a destination. When “Destination” is selected, for example, a screen is displayed for selecting a destination from registered destinations. , Transition to a screen for searching for a destination.

“IPod (registered trademark)” in the basic menu is an item for selecting a music to be played from Apple's iPod (registered trademark) as an audio source. When “iPod (registered trademark)” is selected, The screen transitions to the screen for selecting the music to be played back in FIG. In the first embodiment, since the AVN integrated device is configured on the assumption that iPod (registered trademark) is used as the main source of the audio source, “iPo” is displayed in the basic menu.
d (registered trademark) ”is included. However, it is also possible to use a music playback device other than iPod as the main source of the audio source. In this case, an item indicating the music playback device used as the main source is displayed in the basic menu instead of “iPod”. Is displayed.

“Vehicle” in the basic menu is an item for displaying information related to the vehicle such as the travel distance and fuel consumption of the vehicle equipped with the AVN integrated device. When “vehicle” in the basic menu is selected, the screen changes to a screen that displays information about the vehicle. "Information / G" in the basic menu is an item for selecting information and data management related to the AVN integrated system, VICS (Vehicle Information and Communication System) information, and GPS (Global Positioning System) information. is there. When “Information / G” in the basic menu is selected, the screen changes to a screen for selecting information that the user wants to display from data management, VICS, GPS, or the like.

  When the shortcut menu displayed in the shortcut display area A3 is selected, the operation set in the shortcut menu is performed. For example, when the shortcut menu for reproducing the music A is selected, the music A starts to be reproduced, and the screen changes from the basic menu selection screen to a screen indicating that the music A is being reproduced. If a selection target (music piece, selection item, etc.) is dragged and dropped in the shortcut display area A3 while the shortcut display area A3 is being displayed, a shortcut menu for operations on the selection target is generated.

  FIG. 3 is a diagram illustrating an example of a basic menu selection screen when “iPod” of the basic menu is pushed in the basic menu display area A1. When the basic menu “iPod” is pushed, the screen changes from the basic menu selection screen SC1 shown in FIG. 2 to the basic menu selection screen SC2 shown in FIG. On the screen of the AVN integrated device, not limited to the basic menu selection screen, the display area of the selected item is highlighted, for example, changed to a display color different from other items. On the basic menu selection screen SC2, the display color of the display area of the item “iPod” in the selected basic menu display area A1 is displayed in reverse with other items. In the basic menu selection screen SC2, “source” is displayed on the right side of “iPod” of the selected basic menu. “Source” is an item for selecting an audio source (including iPod) included in the AVN integrated device. When the user slides his / her finger from the “iPod” display area of the basic menu display area A1 to the “source” display area, the screen changes to the basic menu selection screen SC3 shown in FIG. When the user lifts (releases) his / her finger in the “iPod” display area of the basic menu display area A1, “iPod” is selected as the audio source, and the screen changes to a selection start screen SC5 shown in FIG. When the audio source is selected, the music selection process to be reproduced is started.

FIG. 4 shows an example of the basic menu selection screen when the user pushes the “iPod” display area of the basic menu on the basic menu selection screen and then slides his / her finger on the “source” display area. FIG. In the basic menu selection screen SC3, the display color of the “source” display area is inverted when the user slides his / her finger from the “iPod” display area of the basic menu to the “source” display area. When the user releases (releases) the finger in the “source” display area, the screen changes to a basic menu selection screen SC4 shown in FIG.

  FIG. 5 shows the basic menu selection screen when the user pushes the “iPod” display area of the basic menu and then slides the finger to the “source” display area and then releases it. It is a figure which shows an example. In the basic menu selection screen SC4, since “source” is selected in the basic menu selection screen SC3 shown in FIG. 4, the “source” item is displayed instead of the “iPod” item in the basic menu display area A1. ing. In the basic menu display screen SC4, since “source” in the basic menu is being selected, the display color is highlighted and highlighted. Also, on the basic menu selection screen SC4, an audio source list display area A4 including a list of audio sources that can be used by the AVN integrated device is displayed on the right side of the basic menu display area A1 and is superimposed on the navigation display area A2. . For example, audio sources that can be used by the AVN integrated device include AM radio (“AM” in FIG. 5), FM radio (“FM” in FIG. 5), iPod, and television (“TV” in FIG. 5). is there. For example, when the user touches the “iPod” display area in the audio source list area A4, the display color of the “iPod” display area is highlighted and highlighted, and the user releases his / her finger in the “iPod” display area ( Release) and “iPod” is selected as the audio source, and the screen transitions to a selection start screen SC5 shown in FIG. When the audio source is selected, the music selection process to be reproduced is started.

  FIG. 6 is a diagram illustrating an example of a selection start screen serving as a top screen in the music selection process to be played. From the selection start screen SC5, a process of selecting music to be played using the hierarchical structure (playback target music selection process) is started. The selection start screen SC5 includes a first layer display area A5 and a second layer display area A6. In addition, on the selection start screen SC5, at least the first layer display area A5 has such a width that each item name (name of the item to be the root) is displayed. For example, the ratio of the first layer display area A5 and the second layer display area A6 on the screen is preferably 5: 5 to 4: 6.

  In the first layer display area A5, the root of the hierarchical structure is displayed as a list. That is, in the first layer display area A5, for example, playlists, artists, albums, songs, and genres, which are the elements of the first layer of the hierarchical structure shown in FIG. 1, are displayed as list items together with respective icons. Has been. In the second layer display area A6, a list corresponding to the selected item (root) of the first layer is displayed.

  In the first layer display area A5 and the second layer display area A6, the last display state, that is, a list of last modes is displayed. However, when the last mode does not exist in the displayed list, for example, when the AVN integrated device is started from the initial state, the first layer display area A5 is a list composed of the elements (root) of the first layer. Is displayed in an initial state in which no item (element) is selected. In the second layer display area A6, the second layer list corresponding to the top item of the list displayed in the first layer display area A5 is displayed in an initial state in which no item is selected. In FIG. 6, a list including the roots of the hierarchical structure of FIG. 1 is displayed in the initial state in the first layer display area A5, and is displayed in the first layer display area A5 in the second layer display area A6. A “playlist name list” in the second layer of the hierarchical structure having “playlist” at the top of the list as a root is displayed in an initial state. It should be noted that the list to be displayed is displayed in the last mode in any display area of any screen thereafter, and is displayed in the initial state when the last mode does not exist.

In the first layer display area A5 and the second layer display area A6, when the displayed list items do not fit in the display area, the first layer display area A5 and the second layer display area A6 can be scrolled up and down. The list displayed in response to the scroll operation by the user is also scrolled and displayed. In FIG. 6, since all the elements of the hierarchical structure of FIG. 1 are displayed in the first layer display area A5, the first layer display area A5 is not in a scrollable state. In FIG. 6, the playlist name list (see FIG. 1) is displayed in the second layer display area A6, but not all items of the playlist name list are displayed in the second layer display area A6. The second layer display area A6 is scrollable up and down. The user can confirm all items in the playlist name list displayed in the second layer display area A6 by scrolling the finger up and down in the second layer display area A6.

  For example, when the user selects “Artist” from the list displayed in the first layer display area A5, the screen changes to the second layer selection screen SC6 shown in FIG.

  FIG. 7 is a diagram illustrating an example of the second layer selection screen. Second layer selection screen SC6 includes a first layer display area A5 and a second layer display area A6. In the second layer selection screen SC6, the first layer display area A5 is folded to display only the icons of the items of the first layer. Since “Artist” in the first layer display area A5 is selected on the selection start screen SC5 shown in FIG. 6, the display color of the icon indicating the artist in the first layer display area A5 is highlighted and highlighted in FIG. Has been.

  In the second layer display area A6, a second-layer “artist name list” (see FIG. 1) having a hierarchical structure with “artist” as an item selected in the first layer as a root is displayed. Since the artist name list cannot be displayed in the second layer display area A6, the artist name list is scrollable. Further, in the second layer display area A6 of the second layer selection display screen SC6, as in the selection start screen shown in FIG. 6, the last state of the list of the second layer corresponding to the selection item of the first layer (last Mode) is displayed.

  Since the second layer selection screen SC6 is the main screen for selecting items of the second layer, the second layer selection screen SC6 occupies the screen of the second layer display area A6 as compared to the selection start screen SC5 shown in FIG. For example, the display ratio in the screen of the first layer display area A5 and the second layer display area A6 is preferably about 1: 9 to 2: 8.

  For example, when “Artist D” in the second layer display area A6 shown in FIG. 7 is selected, the display color of the “Artist” display area in the second layer display area A6 is highlighted and highlighted. A transition is made to the multi-selection screen SC7 shown in FIG.

  FIG. 8 is a diagram illustrating an example of a multi-selection screen displayed in a state where the first layer, the second layer, and the third layer can be operated. The multi-selection screen is a screen for displaying a plurality of layers in an operable state, and is a screen for mainly selecting the lowest layer item among the displayed layers.

  The multi-selection screen SC7 shown in FIG. 8 includes a first layer display area A5, a second layer display area A6, and a third layer display area A7. In the multi-selection screen SC7 in FIG. 8, a third layer display area A7 is added to the second layer selection screen SC6 shown in FIG. 7, and the third layer display area A7 is displayed in front of the second layer display area A6. It is the state that was done. Therefore, the first layer display area A5 and the second layer display area A6 are the same as the second layer selection screen SC6 shown in FIG.

  In the third layer display area A7, a list of the third layer corresponding to the selected item of the second layer is displayed. In FIG. 8, in the third layer display area A7, an “album name list of artist D” (see FIG. 1) corresponding to “artist D” selected in the second layer is displayed. In FIG. 8, the album name list of artist D fits in the third layer display area A7, so that it cannot be scrolled.

  The multi-selection screen SC7 shown in FIG. 8 has the highest ratio of the third layer display area A7 in the screen because the main screen is to select the third layer item. For example, the display ratio in the screen of the first layer display area A5, the second layer display area A6, and the third layer display area A7 is approximately 1: 4: 5.

  For example, when “Album BB” in the third layer display area shown in FIG. 8 is selected, the display color of the display area of “Album BB” is highlighted and highlighted, and the screen is the multi-select shown in FIG. Transition to screen SC8.

  FIG. 9 is a diagram illustrating an example of a multi-selection screen displayed in a state where the first layer, the third layer, and the fourth layer can be operated. The multi-selection screen SC8 shown in FIG. 9 includes a first layer display area A5, a second layer display area A6, a third layer display area A7, and a fourth layer display area A8. In the fourth layer display area A8, the “music list of album BB” (see FIG. 1) corresponding to the selected item “album BB” in the third layer is displayed. Since the music list items of album BB do not fit in the fourth layer display area A8, the fourth layer display area A8 can be scrolled up and down.

  In the multi-selection screen SC8 shown in FIG. 9, the fourth-layer display area A8 is added to the multi-selection screen SC7 shown in FIG. 8, and the fourth-layer display area A8 becomes the second-layer display area A6 and the third-layer display area. It is a screen displayed on the foremost side by being superimposed on A7. In the multi-selection screen SC8 shown in FIG. 9, the third layer display area A7 is displayed in an operable state for the third layer, which is one layer above the fourth layer, which is the main item selection, For the second layer above the third layer, the second layer display area A6 is folded and displayed to the extent that the display position of the selection item can be understood. However, since the first layer display area A5 is always displayed on the multi selection screen, the first layer display area A5 is also displayed on the multi selection screen SC8 shown in FIG.

  A multi-selection screen SC8 shown in FIG. 9 is a screen for mainly selecting items in the fourth layer. Therefore, in the multi-selection screen SC8 shown in FIG. 9, the ratio of the fourth layer display area A8 in the screen is the highest. For example, in the multi-selection screen SC8 shown in FIG. 9, the display ratio in the screen of the first layer display area A5, the third layer display area A7, and the fourth layer display area A8 is approximately 1: 4: 5. .

  When “music ad” in the fourth layer display area A8 shown in FIG. 9 is selected, the display color of the display area of “music ad” is highlighted and highlighted. Since the fourth layer is the lowest layer of the hierarchical structure with “artist” as the root, when “music ad” is selected, the music selection process to be reproduced is ended and the display of the multi-selection screen is also ended. The screen changes to a selection result output screen SC9 shown in FIG.

  FIG. 10 is a screen showing an example of a selection result output screen. The selection result output screen is a screen for outputting the result of the music selection process to be reproduced.

In practice, the function of each functional block shown in FIG. 17 is realized by the microcomputer (CPU) corresponding to the control unit 100 (FIG. 16) executing the program. A description will be given assuming that each process is executed as a main body.

  Through execution of the display program, the control unit 100 performs a screen display control unit 11, a touch panel operation analysis unit 12, a last mode acquisition unit 13, a last mode reading unit 14, a screen display setting unit 15, an audio data reproduction instruction unit 16, and a basic menu. It operates as the control unit 17 and the shortcut control unit 18. The storage unit 19 is generated in the storage area of the memory 117 through execution of the display program or statically.

  The touch panel operation analysis unit 12 acquires the coordinate information of the touch position of the touch panel by the user from the touch panel 202 at a predetermined cycle, analyzes the operation of the user's finger performed on the touch panel 202 from the coordinate information, and detects the operation by the user. To do. For example, the touch panel operation analysis unit 12 performs operations based on operations such as push, release, scroll, flick, and slide performed on the touch panel 202 and coordinate information and screen information currently displayed on the liquid crystal panel 201. The detected area is detected, and operations (selection, drag and drop, scrolling, etc.) performed by these actions or combinations of actions are detected. The touch panel operation analysis unit 12 outputs an operation analysis result on the touch panel 202 to the screen display control unit 11, the basic menu control unit 17, and the shortcut control unit 18. The analysis result includes at least an operation performed on the screen currently displayed on the liquid crystal panel 201 and a target region of the operation.

  For example, when the screen display transitions, the last mode acquisition unit 13 acquires, as the last mode, the state of the list displayed in each display area in accordance with an instruction from the screen display control unit 11 and stores it in the storage unit 19. To do. The last mode of the list state is, for example, an item selection state. The last mode acquisition unit 13 stores the multi selection screen immediately before the transition as the last screen in the storage unit 19 when, for example, the multi selection screen transits to the selection result output screen. Details of the process for acquiring the last mode, the last screen, and the last mode and the last screen will be described later.

  For example, when the screen display transitions and a new display area is added, the last mode reading unit 14 generates a list of lists to be displayed in the new display area in accordance with an instruction from the screen display control unit 11. The last mode is read from the storage unit 19 and output to the screen display setting unit 15. The last mode control unit 14 reads out the last screen and outputs it to the screen display setting unit 15 at the time of screen transition.

  The screen display setting unit 15 sets a screen to be displayed next in accordance with an instruction from the screen display control unit 11. For example, when a new display area is added to the screen, the screen display setting unit 15 sets the display of the list acquired from the last mode reading unit 14 to the display area in the last mode. The display method of the display area (for example, slide from the right end of the screen) is set. The screen display setting unit 15 outputs the set screen to the image adjustment circuit 108 in accordance with an instruction from the screen display control unit 11.

  When the screen display control unit 11 determines that the music to be played back has been selected, the audio data playback instruction unit 16 plays the selected music with the selected music as the top in accordance with the instruction from the screen display control unit 11. And instructing a predetermined unit to reproduce the music according to the reproduction music list. For example, when the audio source is iPod, the audio data reproduction instruction unit 16 instructs the external recording medium reproduction unit 101 to reproduce the selected music piece. For example, when the audio source is a disc such as a CD or DVD, the audio data playback instruction unit 16 instructs the disc playback unit 104 to play back the selected music piece.

  For example, in the screen transition as described in FIGS. 2 to 10, the screen display control unit 11 instructs each unit to set a screen, to display a screen, to give a last mode, to give a last mode read, to play music List generation, music reproduction start instruction, and the like, and control related to screen transition. For example, the screen display control unit 11 acquires screen information currently being displayed on the liquid crystal panel 201 from the image output unit 110 and stores it in the storage area of the memory 117. When the screen display control unit 11 acquires an operation on the touch panel 202 from the touch panel operation analysis unit 12, the screen display control unit 11 determines the screen transition for the operation and the display change of each display area in the screen, and sets the screen display setting to the screen display setting. The unit 15 is instructed. In addition, a process to be performed for an operation on the touch panel 202 is determined, and a process is instructed to a predetermined unit. For example, when the operation on the touch panel 202 is selection of a music to be played back, the screen display control unit 11 generates a playback music list with the selected music as the top of the list and starts playback of the music as audio data playback. The instruction unit 16 is instructed.

The basic menu control unit 17 is executed in accordance with the display of the basic menu display area A1 and the operation performed on the basic menu display area A1, independently of the screen transition control by the screen display control unit 11. Control the process to be performed. The basic menu control unit 17 has a no-operation time timer, and after the operation signal (coordinate information from the touch panel 202) input from the touch panel 202 or the operation unit 114 is input, the next operation signal is input. Measure the time until. That is, the basic menu control unit 17 measures the no-operation time of the AVN integrated device 1. When the no-operation time reaches a predetermined value (for example, 10 seconds), the basic menu control unit 17
The screen display setting unit 15 is instructed to display the basic menu display area A1. Then, the basic menu display area A1 is displayed on the screen as described in FIG. 15, for example. The basic menu control unit 17 cancels the display of the basic menu display area A1 when an operation is performed on another display area displayed on the screen while the basic menu display area A1 is displayed. In addition, for example, when an item in the basic menu display area A1 is selected, the basic menu control unit 17 instructs the screen display setting unit 15 to transition to a selection start screen corresponding to the selected item. To do.

  The shortcut control unit 18 controls processing to be executed in response to an operation on the shortcut display area A3 independently of the screen transition control by the screen display control unit 11. For example, the shortcut control unit 18 drops an icon or the like displayed in an area other than the shortcut display area A3 displayed on the screen on the shortcut display area A3 based on the analysis result from the touch panel operation analysis unit 12. Judge that. In this case, the shortcut control unit 18 creates a shortcut menu for the process indicated by the icon or the like, and instructs the screen display setting unit 15 to add and display the shortcut menu in the shortcut display area A3. Further, when the shortcut control unit 18 determines that the shortcut menu displayed in the shortcut display area A3 is selected based on the analysis result from the touch panel operation analysis unit 12, the processing of the process indicated by the shortcut menu is performed. Instruct execution to a predetermined unit. For example, when the shortcut menu indicating the reproduction of music A is selected, the shortcut control unit 18 instructs the audio data reproduction instruction unit 16 to reproduce the music A.

  The storage unit 19 holds, for example, a list of hierarchical structures as shown in FIG. 1 and a list that is an element of each hierarchical structure. The storage unit 19 holds, for example, a list last mode, a basic menu display area last mode, a selection start screen last screen, and a multi-select screen last screen, which are elements of each hierarchical structure. In addition, the storage unit 19 holds the shortcut menu displayed in the shortcut display area A3 and the operation state of each shortcut menu.

  FIG. 18 is a diagram illustrating an example of a part of information held in the storage unit 19. The last mode held in the storage unit 10 includes the last mode of the list, which is an element of each hierarchical structure, and the last mode of the basic menu selection area. The last mode of the list that is an element of each hierarchical structure is, for example, the last mode of the list of the m-th layer when focusing on the last mode of the element of the m-th layer (m is a natural number not including 0) of a certain hierarchical structure. For the mode, the last mode of the (m + 1) th layer corresponding to the case where each item is selected is held. That is, when the last mode of the m-th layer list includes S items, the last mode of the m-th layer list holds the S m + 1-th layer last mode. Become.

In OP137, the control unit 100 outputs the multi-selection screen set in OP134 and OP135 to the image adjustment circuit 108 and the image output unit 110, and displays the screen on the screen of the liquid crystal panel 201. As a result, the X-th layer display area disappears from the multi-selection screen, and instead, the X-2th layer display area is displayed. Thereafter, since the multi-selection screen is displayed, the flow of FIG. 28 is started.

  The flow shown in FIGS. 28, 29A, 29B, 30 and 24 includes, for example, the screen display control unit 11, the touch panel operation analysis unit 12, the last mode acquisition unit 13, and the last mode of the functional blocks shown in FIG. This is realized by the cooperation of the reading unit 14 and the screen display setting unit 15.

(Processing for touch panel operation while the selection result output screen is displayed)
FIG. 31 is an example of a flowchart of processing for a touch panel operation during display of the selection result output screen. The flow shown in FIG. 31 starts when the selection result output screen is displayed, and is repeatedly executed while the selection result output screen is displayed. The flow shown in FIG. 31 is finished when the display of the selection result output screen is finished, and the repeated execution is also finished.

  In OP160, the control unit 100 determines from the coordinate information sequentially input from the touch panel 202 whether or not a flick operation from left to right has been performed on the touch panel 202. If a flick operation from left to right is performed (OP160: Yes), the process proceeds to OP161. When the operation is not a left-to-right flick operation and when coordinate information is not acquired from the touch panel 202 (OP160: No), the control unit 100 does not perform any particular processing, and the flow shown in FIG. Execute repeatedly from.

  In OP161, the control unit 100 reads the last screen of the multi selection screen. In OP162, the control unit 100 outputs the last screen of the multi-selection screen to the image adjustment circuit 108 and the image output unit 110, and displays it on the screen of the liquid crystal panel 201. As a result, the screen changes from the selection result output screen to the multi-selection screen. Thereafter, since the multi-selection screen is displayed, the flow of FIG. 28 is started.

  The flow shown in FIG. 31 is realized, for example, by the cooperation of the screen display control unit 11, the touch panel operation analysis unit 12, the last mode reading unit 14, and the screen display setting unit 15 of the functional blocks shown in FIG.

(List scroll processing)
32A and 32B are diagrams for explaining list scroll processing. In the first embodiment, when the displayed list does not fit in the display area, the display area is scrollable. Furthermore, in the first embodiment, when there is an item being selected in the list, the item being selected continues to be displayed in the display area even when the list is scrolled.

  For example, the fourth layer display area A8 of the multi-selection screen shown in FIG. 32A is in a scrollable state, and “4. Music ad” in the fourth layer display area A8 is an item being selected. When the user performs a scrolling operation in the fourth layer display area A8, the list displayed in the fourth layer display area A8 is also scrolled upward (screen SC8-1 in FIG. 32A). . As the list continues to scroll upward, the currently selected item “4. Music ad” is positioned at the upper end of the fourth layer display area A8 (screen SC8-2 in FIG. 32A). Further, when the list is scrolled upward, the currently selected item “4. Music ad” is displayed above the fourth layer display area A8 without departing from the fourth layer display area A8. (Screen SC8-3 in FIG. 32A). On the other hand, items after the item “4. Music ad” being selected in the fourth layer display area A8 (items after “5. Music ae”) are scrolled upward.

  FIG. 32B is a diagram showing an example of screen transition when the user performs a scrolling operation in the fourth layer display area A8 after the screen SC8-3 in FIG. 32A. When the user performs a downward scrolling operation in the fourth layer display area A8, the currently selected item “4. Music ad” remains at the top of the screen, but the other items in the list are downward. (Screen SC8-4 in FIG. 32B). If the list continues to scroll downward, the currently selected item “4. Music ad” returns to the original position in the list (screen SC8-5 in FIG. 32B). Thereafter, when the list is further scrolled downward, the currently selected item “4. Music ad” is displayed at the original position of the list and is moved and displayed together with the scroll of the list (in FIG. 32B). , Screen SC8-6).

  In this way, the currently selected item remains in the display area and continues to be displayed even when the list is scrolled. Thereby, the user can always visually recognize the item being selected. When the item being selected is positioned at the bottom of the screen by scrolling the list, the item being selected remains at the bottom of the screen and is displayed as in FIGS. 32A and 32B.

  FIG. 33 is an example of a flowchart of processing related to fixed display of an item being selected in the list scroll processing described in FIGS. 32A and 32B. The flow shown in FIG. 33 is started when vertical scrolling is detected in a scrollable display area. The flow shown in FIG. 33 is repeatedly executed while scrolling in the vertical direction is performed in the scrollable display area, and when the scrolling is finished, the repeated execution is also finished.

  In OP171, the control unit 100 determines whether there is an item being selected in the display area where scrolling is detected. If there is an item being selected in the display area where the scroll is detected (OP171: Yes), the process proceeds to OP172. If there is no item being selected in the display area where scrolling is detected (OP171: No), the process ends.

  In OP172, the control unit 100 determines whether the currently selected item is fixedly displayed on the upper end (top) or the lower end (bottom) of the screen. If the currently selected item is fixedly displayed at the upper end (top) or lower end (bottom) of the screen (OP172: Yes), the process proceeds to OP173. If the currently selected item is not fixedly displayed at the top (top) or bottom (bottom) of the screen (OP172: No), the process proceeds to OP175.

  In OP173, the control unit 100 determines whether the display position of the item being selected is the upper end (top) or the lower end (bottom) of the display area (screen). If the display position of the selected item is the upper end (top) or the lower end (bottom) of the display area (screen) (OP173: Yes), the process proceeds to OP174. If the display position of the item being selected is not the upper end (top) or the lower end (bottom) of the display area (screen) (OP173: No), the process ends. Thereafter, while scrolling continues, the flow shown in FIG. 33 is repeatedly executed.

  In OP174, the control unit 100 fixedly displays the selected item on the upper end (top) or the lower end (bottom) of the display area (screen). Thereafter, while scrolling continues, the flow shown in FIG. 33 is repeatedly executed.

  In OP175, the control unit 100 determines whether or not the currently selected item fixedly displayed at the upper end (top) or lower end (bottom) of the display area (screen) is displayed at the original position in the list. To do. If the currently selected item is displayed at the original position in the list (OP175: Yes), the process proceeds to OP176. If the currently selected item is not displayed at the original position in the list (OP175: No), the process ends. Thereafter, while scrolling continues, the flow shown in FIG. 33 is repeatedly executed.

  In OP176, since the currently selected item is displayed at the original position in the list, the control unit 100 cancels the fixed display of the currently selected item. Thereafter, while scrolling continues, the flow shown in FIG. 33 is repeatedly executed.

  The flow shown in FIG. 33 is realized by, for example, the cooperation of the screen display control unit 11, the touch panel operation analysis unit 12, and the screen display setting unit 15 of the functional blocks shown in FIG.

(Music playback process)
FIG. 34 is an example of a flowchart of the reproduction process of the music selected in the reproduction target music selection process. The flow shown in FIG. 34 is started, for example, when the control unit 100 instructs the selected music piece to be played in OP127 of the flow of FIG. 29B. Also, the flow shown in FIG. 34 is repeatedly executed until the music reproduction process is stopped by the user's operation.

  In OP181, the control unit 100 determines whether or not the reproduction music list is new. If the reproduction music list is new (OP181: Yes), the process proceeds to OP182. If the reproduction music list is not new (OP181: No), the process proceeds to OP183.

  In OP182, since the reproduction music list is new, the control unit 100 instructs the predetermined part to reproduce the first music in the reproduction music list. When the audio source is iPod, the control unit 100 instructs the external recording medium playback unit 101 to play the first song in the playback song list. Thereafter, the flow shown in FIG. 34 is repeatedly executed until the music reproduction process is stopped by the user's operation.

  In OP183, the control unit 100 determines whether or not the playback of the current playback target music has been completed. When the reproduction of the current music to be reproduced is completed (OP183: Yes), the process proceeds to OP184. In OP184, the control unit 100 instructs a predetermined unit to reproduce the next song in the reproduction song list. If playback of the current playback target music has not been completed (O183: No), the process proceeds to OP185.

In OP185, the control unit 100 determines whether or not a music selection operation for selecting the previous music or the next music of the music currently being reproduced in the reproduction music list is performed. The music selection operation is an operation by pressing a fast forward button, a rewind button, or the like included in the operation unit 114, for example. When the music selection operation is performed (OP185: Yes), the process proceeds to OP186. In OP186, the control unit 100 instructs a predetermined unit to reproduce the target music in the reproduction music list. Thereafter, the flow shown in FIG. 34 is repeatedly executed until the music reproduction process is stopped by the user's operation. When the music selection operation is not performed (OP185: No), the process ends, and the flow shown in FIG. 34 is repeatedly executed until the music reproduction process is stopped by the user's operation.

(Operational effects of the first embodiment)
In the first embodiment, on the multi-selection screen, the first layer, the X-1th layer, and the Xth layer of the hierarchical structure are displayed in an operable state. As a result, when changing the selection item of the different X-1th layer in the hierarchical structure, the operation of displaying the X-1th layer can be omitted, and convenience is increased. In addition, since the first layer is displayed in an operable state on the same screen, when changing the selection item of the first layer, the selection item of the first layer is changed without performing many operations. can do.

  In the multi-selection screen, the first layer, the X-1th layer, and the Xth layer of the hierarchical structure are displayed in an operable state. For example, when selecting an item of the Xth layer, the user The item of the Xth layer can be selected while visually recognizing the selection item of the X-1th layer, which is the layer of X. In addition, when the items of the Xth layer and the X-1th layer cannot be displayed in the display area, the display area of both the Xth layer and the X-1th layer can be scrolled. On the same screen as the X layer, all the items of the X-1 layer that is one level higher can be confirmed, and convenience is enhanced.

  In the multi-selection screen, when the lower layers are displayed from the left to the right, the first layer, the X-1 layer, and the X layer were displayed by flicking from the left to the right The screen can be changed to a screen on which the first layer, the X-2 layer, and the X-1 layer are displayed. That is, the user can display the upper layer on the screen by flicking the display region of the lower layer from the screen to the left to the right. Thus, by linking the operation for instructing the screen transition and the screen display, the operation can be performed more intuitively and the operability is improved.

  In the first embodiment, the item being selected in the list remains in the display area and continues to be displayed even when the list is scrolled. As a result, the user can search for an item while visually recognizing the currently selected item.

Second Embodiment
FIG. 35 is a diagram illustrating a display example of the index display area. In the second embodiment, when a predetermined operation is performed in an area for displaying a list having a predetermined number of items arranged in alphabetical order and alphabetical order, the index characters of the list are displayed. Examples of the list having a predetermined number of items arranged in alphabetical order and alphabetical order include a list of all songs, a list of all artists, a list of all albums, and the like held in the audio source. The condition (predetermined operation) for displaying the index character includes, for example, pressing and holding a certain item, scrolling the list in the same direction a predetermined number of times, scrolling at a predetermined speed or more, and the like. In addition, long press is touching the same position with predetermined pressure for 2 seconds or more, for example.

For example, in the example shown in FIG. 35, when the user long presses the display area of the item “Artist (Aki)” (the name in parentheses is the artist name) in the second layer display area A6 on the second layer selection screen SC12. The index display area A9 is displayed in the right area of the second layer display area A6. When the item “Artist (Aki)” is pressed for a long time, the artist name “Aki” belongs to the A line, so “A” is displayed as an index character in the index display area A9. For example, when the artist name “HTO” is pressed for a long time, “H” is displayed as an index character in the index display area A9.

  When the index display area A9 is displayed, in the second layer display area A6, a list is displayed starting from the item starting with the index character displayed in the index display area A9. For example, when the index letter “H” is displayed in the index display area A9, the list is displayed in the second layer display area A6 with the item starting with “H” as the head.

  For example, when a downward flick is executed in the index display area A9 in the state shown in FIG. 35, the index characters in the index display area A9 are displayed as follows: a → ka → sa → ta →. Transition in order in stages. Further, when alphabets are displayed in the index display area A9, the display of index characters transitions in alphabetical order according to the flick operation. For example, when the index character “H” is displayed in the index display area A9, when a downward flick is executed in the index display area A9, the index character is expressed as H → I → J →. Display changes.

  Further, when a vertical flick, scroll, or the like is performed on the index display area A9, the display of the second layer display area A6 is also linked to the transition of the index character displayed in the index display area A9. To do. For example, when the index character “A” is displayed in the index display area A9, when the display of the index display area A9 is changed to the index character “KA” by flicking or the like, it is displayed in the second layer display area A6. The list is also scrolled from the state where the item starting with “a” is positioned at the head until the item starting with “ka” is positioned at the top.

  In addition, when the list is scrolled in the second layer display area A6 in a state where the index display area A9 is displayed, the index characters displayed in the index display area A9 linked to the scrolling of the list are also changed. For example, in the second layer display area A6, when the list is scrolled from the item starting from “A” to the item starting from “KA”, the index characters displayed in the index display area A9 Also transitions from “a” to “ka”.

  In FIG. 35, the example in which the index display area A9 is displayed in the second layer display area A6 on the second layer selection screen has been described. However, the present invention is not limited to this. If the display area is displayed, the index display area A9 can be displayed.

The index control unit 20 is one of functional blocks realized by the control unit 100 executing a display program. Independent of the screen transition control by the screen display control unit 11, the index control unit 20 controls display and deletion of the index display area A9, transition of index characters to be displayed, and the like. For example, when the index display condition is satisfied in the display area where the index display target list is displayed, the index display area A9 is displayed in the display area, and when the index display end condition is satisfied, the display is performed. The index display area A9 displayed in the area is deleted. The index display condition includes, for example, a long press, the number of continuous scrolls in the same direction, and the scroll speed. For example, the index display end condition is that the index display area A9 is displayed when an operation is performed in a display area other than the display area where the index display area A9 is displayed, or when an item is selected or the screen transitions in the reverse direction. The display area that is displayed is not displayed.

  The index control unit 20 determines whether the index display condition and the index display end condition are satisfied from the analysis result of the operation on the touch panel 202 from the touch panel operation analysis unit 12. Further, information on the display area for displaying the index display target list is acquired from the screen display control unit 11, and the index character to be displayed in the index display area A9 is determined. Further, the index control unit 20 outputs the information of the index display area A9 to the screen display setting unit 15, and the screen display setting unit 15 displays and erases the index display area A9 on the screen in accordance with an instruction from the index control unit 20. Set.

  FIG. 37 is a hierarchical structure list of the second embodiment held in the storage unit 19. The difference from the hierarchical structure list of the first embodiment is that each element is provided with an index display target flag. The index display flag is a flag for indicating that the list as an element is a list of index display targets.

  The index display target list is a list that is arranged according to a rule such as alphabetical order or alphabetical order, and that has a predetermined number (for example, 100) or more items. In the hierarchical structure table shown in FIG. 37, the “artist name list” in the second layer of the hierarchical structure having “artist” as the root, and the “album name list” in the second layer of the hierarchical structure having “album” as the root "," Song name list "in the second layer of the hierarchical structure rooted in" music ", and" artist name list for each genre "in the third layer of the hierarchical structure rooted in" genre " It is set as a list.
