Referring first to FIG. 1 to FIG. 3 and FIG. 21, an overview of the function of an information processing device according to a first embodiment of the present disclosure will be described. FIG. 1 is an illustration showing an example of an external appearance of an information processing device according to first and second embodiments of the present disclosure.

Hereinafter, in the present specification and the drawings, an information processing device 100 will be referred to when describing features that are common between an information processing device 100a according to the first embodiment of the present disclosure and an information processing device 100b according to the second embodiment.
The information processing device 100 is a display control device having a display device or a function of controlling the display of an external display device. The information processing device 100 may be an information processing device such as a PC (Personal Computer), a household video processing device (a DVD recorder, a VCR, or the like), a PDA (Personal Digital Assistant), a household game device, or a household electric appliance, for example. Alternatively, the information processing device 100 may be an information processing device such as a mobile phone, a PHS (Personal Handyphone System), a portable music player device, a portable video processing device, or a portable game device. Hereinafter, it is assumed that the information processing device 100 is a mobile phone having a touch panel on the front surface thereof.
The information processing device 100a has a function of displaying a content item 40 as shown in FIG. 2, for example, on the display screen. Then, the information processing device 100a can display a portion of the content item 40 on the display screen. The information processing device 100a may determine a display area of the content item 40 in response to a user operation. The information processing device 100a may move the display area by an amount determined based on a user operation. Alternatively, the information processing device 100a may set a plurality of display areas in the content item 40 in advance, and select and display one of the display areas based on the direction of a user operation. For example, as shown in FIG. 3, a first display area 41, a second display area 42, a third display area 43 and a fourth display area 44 may be set in the content item 40. It is preferred that these display areas are set at such positions in the content item 40 that the viewability of information is high. With such a configuration, it is possible to reduce the burden on the user for viewing information. A commonly-displayed object 50 to be later described in detail may be selected from among objects included in the content item 40.
Note that in the present disclosure, a commonly-displayed object is used to indicate which part of the entire content item 40 corresponds to which of these display areas. FIG. 4 shows an example arrangement of a commonly-displayed object. For example, in State 1 in which the first display area 41 is displayed, since the first display area 41 is an upper left portion of the content item 40, a commonly-displayed object 51, which is an upper left portion of the commonly-displayed object 50, is included in the display image. A user who sees the commonly-displayed object 51 can recognize that only a part of the object of the commonly-displayed object Si is displayed. It is also possible to recognize that a right portion of the object is missing, and it is therefore possible to grasp that the first display area 41 is a left portion of the content item 40.
In State 2 in which the second display area 42 is displayed, since the second display area 42 is a lower left portion of the content item 40, a commonly-displayed object 52, which is a lower left portion of the commonly-displayed object 50, is included in the display image. A user who sees the commonly-displayed object 52 can recognize that the commonly-displayed object 52 is a portion of the object. Since a right portion of the object is missing, it is possible to recognize that the second display area 42 is a left portion of the content item 40. Moreover, when transitioning from State 1 to State 2, the commonly-displayed object 50 is displayed even during the transition. Therefore, one can intuitively recognize that State 2 is a lower portion of State 1.
In State 3 in which the third display area 43 is displayed, since the third display area 43 is a lower center portion of the content item 40, a commonly-displayed object 53, which is a lower center portion of the commonly-displayed object 50, is included in the display image.
In State 4 in which the fourth display area 44 is displayed, since the fourth display area 44 is a lower right portion of the content item 40, a commonly-displayed object 54, which is a lower right portion of the commonly-displayed object 50 is included in the display image.
Then, the information processing device 100a may determine the layout so that the entire portion of the commonly-displayed object 50 will be displayed when all of the display areas included in the content item 40 are displayed.
For example, one might employ a method of switching between a list display and a detailed display as shown in FIG. 21 for an overview characteristic, for example. However, according to the method of the present disclosure, a user can recognize the position of detailed information with respect to the entirety without switching the display.
A configuration of such an information processing device 100a will next be described in detail.
1-2. Configuration
Referring next to FIG. 5 to FIG. 11, a functional configuration of the information processing device 100a according to the first embodiment of the present disclosure will be described. FIG. 5 is a block diagram showing a functional configuration of the information processing device according to the embodiment. FIG. 6 is an illustration of an example of a display area changing operation and an animation direction determination method of the information processing device according to the embodiment. FIG. 7 is an illustration of another example of a display area changing operation and an animation direction determination method of the information processing device according to the embodiment. FIG. 8 is an illustration showing a relationship between the size of a display area and the size of a commonly-displayed object of the information processing device according to the embodiment. FIG. 9 is an illustration of a process for determining a display position of a commonly-displayed object of the information processing device according to the embodiment. FIG. 10 is an illustration showing an example of an animation representation used when changing the display area of the information processing device according to the embodiment. FIG. 11 is an illustration showing another example of an animation representation used when changing the display area of the information processing device according to the embodiment.
Referring to FIG. 5, the information processing device 100a of the present embodiment primarily includes a content obtaining section 105, a commonly-displayed object determination section 110, an operation information obtaining section 115, a layout determination section 120a, a display image generating section 125, and a display section 130.
(Content Obtaining Section 105)
The content obtaining section 105 has a function of obtaining content items to be displayed on the display screen. The content obtaining section 105 may obtain content items stored inside the information processing device 100a. Alternatively, the content obtaining section 105 may obtain content items from an external device connected thereto via a network.
(Commonly-Displayed Object Determination Section 110)
The commonly-displayed object determination section 110 has a function of determining the commonly-displayed object 50, which is commonly displayed even when the display area is changed, while a content item is displayed. If the content item includes information of a commonly-displayed object, the commonly-displayed object determination section 110 may determine the commonly-displayed object according to this information by referencing the information. The commonly-displayed object determination section 110 may determine a commonly-displayed object from among objects included in the content item based on feature value information obtained by analyzing objects included in the content item.
(Operation Information Obtaining Section 115)
The operation information obtaining section 115 may include an input section for allowing a user to input information, for example, and an input control circuit for generating an input signal based on the input, etc. For example, an example of the input section may be a touch panel, a mouse, a keyboard, a button, a microphone, a switch, a lever, or the like.
(Layout Determination Section 120a)
The layout determination section 120a has a function of determining a layout of a display image based on information of a commonly-displayed object determined by the commonly-displayed object determination section 110 using a content item obtained by the content obtaining section 105, and operation information obtained by the operation information obtaining section 115. Now, an example of the determination of the display area, the layout of the commonly-displayed object, and the animation representation used when changing the display area will be described.
In the present embodiment, the layout determination section 120a determines the layout by cutting out a partial area of the content item 40, and superimposing the commonly-displayed object on the cut-out display area. For example, a user performs an operation on the display screen using the operator F in a state where the first display area 41 is displayed, as shown in FIG. 6. When the traveling distance becomes greater than or equal to a predetermined distance, the layout determination section 120a can determine the animation direction based on the direction of the traveling path over this predetermined distance. The layout determination section 120a can use, as the display area to be displayed next, the second display area 42 which is present in this animation direction in the content item 40.
Referring next to FIG. 7, an another example of animation direction and display area determination is shown. When the operator F moves as shown by an arrow in FIG. 7, the animation direction is determined based on this traveling path. Then, the layout determination section 120a can use, as the display area to be displayed next, the third display area 43 which is present in this animation direction in the content item 40.
As shown in FIG. 8, the layout determination section 120a may determine the size in which the commonly-displayed object 50 is displayed based on the ratio between the size of the display area and that of the content item 40. For example, as the proportion by which the display area occupies the content item 40 is larger, the size of the commonly-displayed object 50 to be displayed may be larger. For example, the proportion by which the first display area 41 occupies the content item 40 is larger than the proportion by which the second display area 42 occupies the content item 40. Then, the layout determination section 120a may determine the size of a commonly-displayed object 50a to be superimposed on the first display area 41 to be larger than the size of a commonly-displayed object 50b to be superimposed on the second display area 42.
The position at which the commonly-displayed object 50 is superimposed on the image of a display area may be determined based on the positional relationship between the center C of the content item 40 and the center of the display area, for example. For example, referring to FIG. 9, for the first display area 41, the position at which the commonly-displayed object 50 is displayed is determined based on the positional relationship between the center C of the content item 40 and the center C1 of the first display area 41, specifically, the direction of the center C of the content item 40 as seen from the center C1 of the first display area 41 and the distance between the center C1 of the first display area 41 and the center C of the content item 40. With such a method, for the first display area 41, which is an upper left partial area of the content item 40, an upper left partial area of the commonly-displayed object 50 is superimposed on a lower right portion of the first display area 41.
Similarly, for the second display area 42, the position at which the commonly-displayed object 50 is displayed is determined based on the positional relationship between the center C of the content item 40 and the center C2 of the second display area 42. With such a method, for the second display area 42, which is a lower left partial area of the content item 40, a lower left partial area of the commonly-displayed object 50 is superimposed on an upper right portion of the second display area 42.
Next, an example of an animation representation used when changing the display area will be described. For example, as shown in FIG. 10, by displaying a portion of C during the transition from A to B, a user can recognize the presence of C during the transition from A to B. Examples of animation representation for use herein may be enlarging/reducing, overshooting, etc. In this case, the layout determination section 120a operates so that a display area 412, which is displayed during the transition from the first display area 41 to the second display area 42, contains information of C.
Similarly, in FIG. 11, by displaying a portion of C during the transition from A to B, a user can recognize the presence of C during the transition from A to B. In this case, the layout determination section 120a operates so that a display area 123, which is displayed during the transition from the second display area 42 to the third display area 43, contains information of C.
Note that the animation representation may be an animation representation suitable for the attribute of the object to be displayed. For example, it is possible to display a button object having a function of allowing one to vote for an object representing a coordination included in the content item 40. In this case, it is preferred that an animation representation that does not involve a change in the display position, such as fading, is used for the button object so that the positional relationship between the button and the item associated therewith will not be unclear and so that the possibility of an erroneous operation is reduced.
It is also preferred that translation+scaling is used in order to maintain the continuity of an image object, or the like. It is important for a text object to maintain its viewability. Therefore, it is preferred to use translation with a reduced α value or fading. Translation, for example, is not preferred as an animation representation for use with a text object because of its heavy visual burden on the user.
(Display Image Generating Section 125)
The display image generating section 125 has a function of generating a display image in accordance with the layout determined by the layout determination section 120a. The display image generating section 125 is capable of supplying the generated display image to the display section 130.
(Display Section 130)
The display section 130 has a function of providing, to a user, the display image generated by the display image generating section 125. Here, the display section 130 includes a display device, and a display control section for controlling the content to be displayed on the display device. However, the present technique is not limited to such an example. For example, the display section 130 may be a display control section for controlling the display of an external display device. The display device may be, for example, a liquid crystal display (LCD: Liquid Crystal Display) device, an organic EL (OLED: Organic Light Emitting Diode) display device, or the like.
An example of the function of the information processing device 100a according to the present embodiment has been described above. Each component described above may be implemented by using a general-purpose member or circuit, or ma be implemented by hardware specialized in the function of the component. The function of each component may be performed by loading a control program, describing procedures for an arithmetic unit such as a CPU (Central Processing Unit) to implement the function, from a storage medium such as a ROM (Read Only Memory) or a RAM (Random Access Memory) storing the control program, and by interpreting and executing the program. Therefore, the configuration to be used may be changed as necessary depending on the level of technology at the time of carrying out the present embodiment. Note that an example of the hardware configuration of the information processing device 100a will be described later in detail.
Note that a computer program for implementing the functions of the information processing device 100a according to the present embodiment as described above may be produced and installed on a personal computer, or the like. It is also possible to provide a computer-readable recording medium having such a computer program stored therein. The recording medium may be a magnetic disk, an optical disk, a magneto optical disk, a flash memory, or the like, for example. The computer program described above may be distributed via a network, for example, without using a recording medium.
1-3. Operation Example
Referring next to FIG. 12, an operation example of the information processing device 100 according to the first embodiment of the present disclosure will be described. FIG. 12 is a flow chart showing an operation example of the information processing device according to the embodiment.
Referring to FIG. 12, first, it is determined whether a touch operation is in progress based on operation information 115 (S100). If it is determined that a touch operation is in progress, it is next determined whether an animation direction has already been defined (S105). If it is determined in step S105 that an animation direction has not yet been defined, it is next determined whether a drag operation has been performed over a predetermined distance or more (S110). If a drag operation is performed over a predetermined distance or more, an animation direction is defined based on the path of this drag operation (S115).
On the other hand, if it is determined in step S105 that an animation direction has already been defined, an animation is updated in accordance with the amount of touch movement (S120).
On the other hand, if it is determined in step S100 that a touch operation is not in progress, it is next determined whether an animation is in progress (S125). If it is determined in step S125 that an animation is not in progress, it is next determined whether the finger, which is the operator F, has been lifted up (S130). Then, if it is determined that the finger has been lifted up, it is next determined whether a drag operation has been performed over a predetermined distance or more (S135).
If it is determined in step S135 that a drag operation has been performed over a predetermined distance or more, an animation is then started (S140). On the other hand, if it is determined in step S125 that an animation is in progress, the animation is updated (S145). Then, it is determined whether the display has ended (S150). The process described above is repeated until the display ends.
2. Second Embodiment
2-1. Overview
In the first embodiment, a display image is generated by cutting out a portion of the content item 40 to be displayed. In this case, the position of the display area to be recognized by a user is a position within the content item 40, and the layout of the content item 40 is determined in advance. In contrast, the information processing device 100b to be described in the second embodiment newly generates a screen by selecting an object to be displayed from among objects included in the content item 40. In this case, since the overall layout is not determined in advance, the commonly-displayed object 50 represents the positional relationship with the display area which was displayed immediately before.
2-2. Configuration
Referring next to FIG. 13 to FIG. 18, a functional configuration of the information processing device 100b according to the second embodiment of the present disclosure will be described. FIG. 13 is a block diagram showing a functional configuration of the information processing device according to the second embodiment of the present disclosure. FIG. 14 is an illustration showing an example of a layout generated by the information processing device according to the embodiment. FIG. 15 is an illustration of animation direction determination by the information processing device according to the embodiment. FIG. 16 is an illustration of a limitation on the types of information to be displayed depending on the operation direction of the information processing device according to the embodiment. FIG. 17 is an illustration of a commonly-displayed area displayed by the information processing device according to the embodiment. FIG. 18 is an illustration of a layout generation method of the information processing device according to the embodiment.
Referring to FIG. 13, a configuration of the information processing device 100b according to the second embodiment of the present disclosure is shown. The information processing device 100b primarily includes the content obtaining section 105, the commonly-displayed object determination section 110, the operation information obtaining section 115, a display object determination section 117, a layout determination section 120b, the display image generating section 125, and the display section 130. The information processing device 100b further includes the display object determination section 117, in addition to the configuration of the information processing device 100a according to the first embodiment. The following description will primarily focus on the differences from the information processing device 100a. 
(Display Object Determination Section 117)
The display object determination section 117 has a function of determining a display object from a content item obtained by the content obtaining section 105. The display object determination section 117 may determine a display object from among those of the objects included in the content item that have not been displayed yet, for example.
(Layout Determination Section 120b)
The layout determination section 120b has a function of determining a layout including the position and the size to display the display object determined by the display object determination section 117, in addition to the position and the size to display the commonly-displayed object 50.
For example, as shown in FIG. 14, if a drag operation is detected in a state where a display area 61 is displayed, the animation is updated in response to the drag operation while the display object to be displayed next in a display area 62 and the position and the size of the commonly-displayed object are determined. Here, an object containing the text “THE PANTS COLLECTION” is used as the commonly-displayed object 50. Note that as described above the positional relationship between the display area 61 and the display area 62 is not determined in advance. If an operation using the operator F is detected, the layout determination section 120b can determine the layout of the display area 62 and generate the display screen.
Note that the layout determination section 120b can determine the layout based on operation information obtained by the operation information obtaining section 115. For example, as shown in FIG. 15, a drag operation is started within a display area. Then, when the drag operation has been performed over a predetermined distance or more, the animation direction is defined based on this path, then, when a drag operation is performed past the predetermined distance, the animation is allowed to proceed by a distance that is obtained by orthogonally projecting the path in the defined animation direction.
A limitation may be imposed on the information to be displayed depending on the operation direction. For example, the direction, which is an extension of the operation direction for displaying the information being currently displayed, may be defined as the direction for displaying the next information (the next object). The direction perpendicular to the operation direction may be defined to be the direction for displaying parallel information for the object being currently displayed. Herein, parallel information may be detailed information of an item included in the object being currently displayed, for example.
FIG. 17 shows a commonly-displayed area that is commonly displayed when transitioning from the display area 61 to the display area 62. This includes the commonly-displayed object 50. With this commonly-displayed area, a user can recognize the positional relationship between the display area 61 and the display area 62. Note that while the positional relationship of a screen to be displayed next is not predetermined in the present embodiment but the screen to be displayed next is generated in response to an operation, a positional relationship once determined is stored. That is, after an operation of transitioning from the display area 61 to the display area 62 is performed to display a screen of the display area 62, if an operation of transitioning in the opposite direction to this operation is detected, the display area 61 is displayed again.
Now, when transitioning from the display area 61 to the display area 62 as shown in FIG. 18, an animation direction is determined based on a drag operation. When a drag operation is detected, a display object to be displayed next is determined. The display position of this display object is determined based on the amount of drag operation, or the like. Then, a position is defined such that the commonly-displayed area has a certain area. Then, a position is defined such that this commonly-displayed area has a certain area. Then, the scale and the position of the object are adjusted so that the information of the display object is maximized in this display area 62. Note that an adjustment may be made by rotating the object. The transmittance of the object may be changed as the animation proceeds.
2-3. Operation Example
Referring next to FIG. 19, an operation example of the information processing device 100b according to the second embodiment of the present disclosure will be described. FIG. 19 is a flow chart showing an operation example of the information processing device according to the embodiment.
Referring to FIG. 19, first, it is determined whether a touch operation is in progress based on operation information 115 (S100). If it is determined that a touch operation is in progress, it is next determined whether an animation direction has already been defined (S105). If it is determined in step S105 that an animation direction has not yet been defined, it is next determined whether a drag operation has been performed over a predetermined distance or more (S110). If a drag operation is performed over a predetermined distance or more, an animation direction is defined based on the path of this drag operation (S115).
On the other hand, if it is determined in step S105 that an animation direction has already been defined, an animation is updated in accordance with the amount of touch movement (S120).
