  The present invention relates to a content display device, a control method, a mobile terminal, a program, and a recording medium, and in particular, displays a thumbnail image representing content and has a touch panel function, a control method for the content display device, a mobile terminal, and the content display device. The present invention relates to a program and a recording medium for operating these means.

  A terminal equipped with a browser function for displaying a plurality of thumbnail images side by side is known. Many of these display a plurality of thumbnail images side by side on a two-dimensional plane.

  In recent years, devices having a touch panel function have been developed in various devices such as portable devices and handheld devices. When the user touches the display of the device, the animation displayed on the display, such as scrolling, can be changed.

  Scrolling is the action of sliding the direction of content, such as text, drawings or images, horizontally or vertically across a screen or display window. This scroll operation is disclosed in, for example, Patent Document 1.

  In Patent Document 1, when a scroll operation is performed with respect to a user input, the user input is stopped, and then a predetermined deceleration rate is applied to the input speed of the user by a drag operation to reduce the speed until the scroll is stopped. .

International Publication No. 2008/085877 Pamphlet (Published July 17, 2008)

  However, in Patent Document 1, the position where the scroll is stopped is obtained from the input speed and the deceleration rate of the user, and the position where the scroll is stopped is indefinite. For this reason, when the screen is scrolled in order to search for an image corresponding to the target content, the image displayed on the screen may be missing when the scrolling is stopped. In this case, in order to confirm the missing image, the user must perform an operation of scrolling the screen again to display the entire image, which may be annoying.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a content display device capable of improving user operability.

  In order to solve the above problems, a content display device according to the present invention displays a part of a three-dimensional object in which a plurality of images representing content are arranged on each side of a polygonal column, and a display unit on the display unit. An input unit that is installed and receives a user input by contact; a contact detection unit that detects a movement of a position touched by the user input; and the contact detection unit in a longitudinal direction of the polygonal column during display of a certain screen. A first display control means for scrolling the display area of the three-dimensional object in the longitudinal direction to display another screen different from the certain screen, and during the display of the certain screen. When the contact detection means detects a movement in a direction orthogonal to the longitudinal direction of the polygonal column, the three-dimensional object is rotated with the longitudinal axis of the polygonal column as a rotation axis. The second display control means for moving the display area to display another screen different from the certain screen, and the first display so that a part of the image displayed on the other screen is not interrupted. The display control means and the mobility determination means for determining the mobility of the display area moved by the second display control means are provided.

  In order to solve the above problems, a control method according to the present invention is provided on a display unit that displays a part of a three-dimensional object in which a plurality of images representing content are arranged on each side of a polygonal column, and the display unit is installed on the display unit. A content display apparatus control method comprising: an input unit that receives a user input by contact; and a contact detection step of detecting a movement of a position touched by the user input, and the contact detection step. When movement of the polygonal column in the longitudinal direction is detected during the display of the screen, the display area of the three-dimensional object is scrolled in the longitudinal direction to display another screen different from the certain screen. In the display control step 1 and the contact detection step, a movement in a direction perpendicular to the longitudinal direction of the polygonal column is detected during display of a certain screen. A second display control step of displaying a different screen from the certain screen by moving the display area so as to rotate the three-dimensional object with the longitudinal axis of the polygonal column as a rotation axis; A mobility determination step for determining the mobility of the display area moved in the first display control step and the second display control step so that a part of the image displayed on the screen is not interrupted. It is characterized by that.

  According to said structure, the content display apparatus of this invention displays on a screen the some image arrange | positioned on the virtual three-dimensional object of a polygonal column, and each side surface thereof. A user input by contact is made to the input unit, and the contact detection means detects the movement of the position touched by the user input.

  In the content display device, when movement of a polygonal column in the longitudinal direction (hereinafter, also referred to as “vertical direction”) is detected during display of a certain screen, the display area of the three-dimensional object is scrolled in the longitudinal direction to display another screen. Display. The other screen here refers to another area in the side surface to be displayed before scrolling. That is, in the present invention, the entire three-dimensional object is not displayed on the display unit, but a part thereof is displayed.

  Further, when a movement in a direction perpendicular to the longitudinal axis of the polygonal column is detected during display of a certain screen, the display area is rotated about the longitudinal axis of the three-dimensional object and another screen is displayed. The other screen here is a different side surface from the side surface that is the display target before the rotation. However, it may return to the original side again after rotation.

  In this specification, the central axis of the polygonal column refers to an axis that passes through the center of gravity of the bottom surface of the polygonal column and is orthogonal to the bottom surface of the polygonal column.

  As described above, in the present invention, by scrolling or rotating a three-dimensional object that is not entirely displayed on the screen in the virtual three-dimensional space, an image of content arranged in an area that has not been displayed is displayed. Can be made.

  In addition, the operation of rotating the polygonal column object or changing the portion viewed from the side in the vertical direction is reminiscent of the operation of the rotary bookshelf placed in a bookstore or the like. Therefore, even a person who contacts the content display device for the first time or a person who is unfamiliar with the operation of the device can easily understand the operation method.

  Furthermore, according to the present invention, when the display area of the three-dimensional object is scrolled vertically within the same side surface or rotated to another side surface, the image displayed on the screen is moved without interruption. .

  For example, when the user scrolls the display area by flicking the screen lightly with a finger, the scrolling movement is continued to some extent even after the finger is released from the screen. At this time, depending on the position where the scroll movement is stopped, the content image displayed on the screen may be interrupted. In this case, in order to confirm the missing image, the user must perform an operation of scrolling the screen again to display the entire image, which may be bothersome.

  According to the present invention, since the mobility of scrolling or rotation is determined so that the image displayed on the screen is not interrupted after movement, the image is not lost and the operability for the user can be improved.

  According to the above configuration, in the content display device, when the three-dimensional object is rotated about the longitudinal axis of the three-dimensional object, the number of surfaces on which the display area is moved is determined according to the speed of movement. That is, when the user performs an input operation in a direction orthogonal to the longitudinal direction of the three-dimensional object, the rotational movement is controlled in units of planes.

  Further, the side surface that becomes the display area by the rotational movement is displayed so as to be parallel to the display surface of the display unit. That is, display is performed such that the side surface to be displayed faces the front. Therefore, even if the display area is moved, the image can be displayed within the range of the screen without interruption.

  In the content display device according to the present invention, a category of content is defined for each side of the three-dimensional object, and an image arranged on each side is an image of content belonging to the category defined for the side. Preferably there is.

  According to the above configuration, each side includes content classified into a common category for each side. Therefore, it becomes easier to manage the content and search for the target content becomes easier.

  In the content display device according to the present invention, the content may be an electronic book, and the image may be a thumbnail image of the electronic book.

  As described above, since the content display device of the present invention can change the display area of the three-dimensional object in which a plurality of images are arranged by scrolling or rotating, it is possible to easily view many content images. If the image arranged in the three-dimensional object corresponds to an electronic book, the user can visually search various books as if they were in a bookstore.

  In order to solve the above-described problems, a mobile terminal according to the present invention includes the content display device of the present invention.

  According to the above configuration, the user can visually search various books as if they were in a bookstore at various places.

  The content display apparatus may be realized by a computer. In this case, a program for causing a computer to operate as each of the above-described means and a computer-readable recording medium recording the program also fall within the scope of the present invention.

The displayed area can be moved.

  At this time, the movement of the display area by the user's input operation is controlled so that the image displayed on the screen after the movement is not interrupted. Therefore, when a user searches for a desired content from among a plurality of contents arranged in a three-dimensional object, an image displayed on a screen where scrolling or rotation is stopped is not lost, and thus a target image can be easily searched. can do.

[3D object]
Here, the three-dimensional object displayed in the content display device according to the present embodiment will be described.

  FIG. 2 is a diagram showing a screen of a content display device displaying a three-dimensional object and a part thereof. The right side in the figure represents the appearance of the three-dimensional object 200, and the left side in the figure represents the screen 20 of the content display device displaying a part of the three-dimensional object 200. In FIG. 2, a display area 14 indicated by a broken line frame is an area that is actually displayed on the screen 20 in the three-dimensional object 200.

  In the present embodiment, the three-dimensional object 200 is a rectangular parallelepiped having four side surfaces 11, and has a book shelf structure in which a plurality of electronic books (contents) are arranged on each side surface. Hereinafter, the three-dimensional object may be referred to as a bookshelf object, and the side surface may be referred to as a shelf surface.

  As shown in FIG. 2, the bookcase object 200 has four shelf surfaces 11, and each shelf surface 11 is provided with a plurality of shelves 13. A thumbnail image (also referred to simply as “image”) 12 representing the cover of a plurality of electronic books is displayed on each shelf 13, and the user performs a selection operation on any one of the thumbnail images 12. By doing so, it becomes possible to browse the contents of the electronic book corresponding to the selected thumbnail image 12.

  Examples of the input operation by the user include a method of directly touching the display screen and an operation from an input key or the like provided on the content display device. That is, the content display device of the present embodiment includes a touch panel, and the user can perform various operations by touching the touch panel (screen).

  Examples of the input operation method for the touch panel include a tap operation, a drag operation, a flick operation, or a pinch operation. The tap operation refers to an operation of tapping the screen with a finger, for example, starting a viewer or pressing a displayed button. The drag operation refers to an operation of moving a finger on the screen, and for example, rotation or scrolling of the bookshelf object 200 is executed. The flick operation refers to an operation of lightly touching the screen with a finger, for example, rotating or scrolling the bookshelf object 200. The pinch operation refers to an operation of pinching the screen with two fingers, and for example, enlargement / reduction of the bookshelf object 200 is executed.

  Thus, the user can change the image 12 displayed on the screen 20 by scrolling up and down the display area to be displayed or rotating the bookshelf object 200 by directly touching the screen. .

  The shape of the three-dimensional object is not limited to a rectangular parallelepiped, and may be another polygonal column. In FIG. 2, there are five shelves 13 on which four electronic books are arranged, but the number of contents to be arranged is not limited, and the manufacturer may set as appropriate. A display example of the bookcase object 200 will be described later.

  Next, the detail of each structure with which the content display apparatus which concerns on this embodiment is provided is demonstrated.

[Each component of the content display device]
FIG. 1 is a block diagram showing a configuration of a content display apparatus according to an embodiment of the present invention. As shown in FIG. 1, the content display device 100 includes an input unit 1, a contact detection unit 2 (contact detection unit), a book display processing unit 3, a book database 4, a network management unit 5, and a mobility determination unit 6 (mobility). A determination unit), a scroll control unit 7 (first display control unit), a rotation control unit 8 (second display control unit), an object display processing unit 9, an output processing unit 10, and a display unit 19.

  The input unit 1 is installed on the display unit 19 and accepts user input by contact. That is, in the present embodiment, the input unit 1 and the display unit 19 constitute an integrated touch panel.

  The contact detection unit 2 detects input information from a user input received by the input unit 1, that is, contact. The input information detected by the contact detection unit 2 is, for example, movement information such as a contact position, speed, or distance, and the detected input information is transmitted to the book display processing unit 3 or the mobility determination unit 6.

  The book display processing unit 3 acquires book data to be displayed from the book database 4, generates a thumbnail image 12 for displaying the cover of the acquired book, and sends the thumbnail image 12 to the output processing unit 10. Further, the book display processing unit 3 can send the displayed book to the book database 4 and delete it from the bookshelf object 200. Arrangement and deletion of books on the bookshelf object 200 by the book display processing unit 3 may be performed in accordance with a user input to the input unit 1 or may be automatically performed in accordance with a preset reference (for example, a display period). .

  The book database 4 stores the book data acquired by the network management unit 5 in a storage device and manages the acquired book data. Further, the book data is sent to the book display processing unit 3 in response to an acquisition request from the book display processing unit 3.

  The network management unit 5 acquires book data that is content data from a server on the network via a communication unit (not shown).

  The mobility determination unit 6 determines the mobility when moving the display area of the bookshelf object 200 to be displayed on the screen 20 based on the motion information detected by the contact detection unit 2. Specifically, when the contact detection unit 2 detects the movement of the bookcase object 200 in the longitudinal direction (vertical direction), the mobility determination unit 6 sets the display area of the bookcase object 200 in the vertical direction based on the speed of the movement. The number of lines (mobility) when scrolling is determined and information on the determined mobility is transmitted to the scroll control unit 7. On the other hand, when the contact detection unit 2 detects a movement of the bookcase object 200 in a direction orthogonal to the longitudinal direction, the mobility determination unit 6 moves the display area so as to rotate the bookcase object 200 based on the speed of the movement. The number of surfaces (mobility) to be used is determined, and information on the determined mobility is transmitted to the rotation control unit 8.

  At this time, when the display area is moved during display of a certain screen and another screen is displayed, that is, when the display area in the bookcase object 200 is moved, the mobility determination unit 6 moves to another screen. The mobility is determined so that a part of the displayed image 12 of the electronic book is not interrupted. Such determination of mobility is performed particularly when touched by a flick operation.

  That is, by changing the speed of the user input to the input unit 1, the distance when the display area is scrolled or rotated can be changed. Therefore, even with a single input operation, for example, an image row can be moved by one row or moved by two rows according to the speed. Therefore, the user can operate more comfortably.

  The criteria for determining the mobility are not particularly limited. For example, the mobility may be calculated using a predetermined parameter prepared in advance.

  Moreover, it is preferable that the mobility determination part 6 determines the moving speed of a display area based on the speed of the said movement. For example, when the flick operation speed is high, the moving speed is increased, and when the flick operation speed is low, the moving speed is determined to be low.

  Thereby, for example, when the user wants to find the target content in advance, it is possible to display the desired content in a short time by increasing the contact speed. In addition, when the content that the user wants to browse is not particularly determined and it is desired to display the content while searching for it, the content can be comfortably searched by reducing the contact speed.

  The scroll control unit 7 creates animation information for scrolling the display area of the bookshelf object 200 in the longitudinal direction and displaying another screen according to the mobility determined by the mobility determination unit 6.

  The other screen here refers to another area in the side surface 11 that is a display target before scrolling. This scroll movement is a vertical movement within the shelf surface 11 designated in the display area. The scroll control unit 7 transmits the created animation information to the object display processing unit 9.

  In this specification, animation refers to a function of changing the display by rotating the bookshelf object 200 or moving the shelf surface 11 in the virtual three-dimensional space.

  The rotation control unit 8 uses the central axis (longitudinal axis) of a rectangular parallelepiped whose display area of the bookcase object 200 is indicated by “X” in FIG. 2 as the rotation axis according to the mobility determined by the mobility determination unit 6. Animation information for creating another screen by rotating in a direction orthogonal to the direction is created.

  The other screen here is a different side surface from the side surface that is the display target before the rotation. However, it may return to the original side again after rotation. In the present specification, the central axis of the rectangular parallelepiped refers to an axis that passes through the center of gravity of the bottom surface of the rectangular parallelepiped and is orthogonal to the bottom surface of the rectangular parallelepiped.

  In addition, when the rotational movement stops, the rotation control unit 8 moves the shelf surface 11 displayed on the screen 20 so as to face the front. Here, the front surface is a surface when the shelf surface 11 serving as a display area and the display surface of the display unit 19 are displayed so as to be parallel to each other. The rotation control unit 8 transmits the created animation information to the object display processing unit 9.

  The object display processing unit 9 generates an image of the bookcase object 200 to be displayed by the display unit 19 from the animation information created by the scroll control unit 7 or the rotation control unit 8 and transmits the image to the output processing unit 10.

  The animation information used when the object display processing unit 9 generates the image of the bookcase object 200 is not limited to the scroll movement or the rotation movement, and for example, animation information that adds other visual effects may be used. . Examples of other visual effects include enlargement / reduction of the shelf surface 11, transparency of the bookcase object 200, change of the background image, and the like.

  The output processing unit 10 arranges the thumbnail image 12 on the shelf surface 11 of the book shelf object 200 from the thumbnail image 12 of the book generated by the book display processing unit 3 and the image of the book shelf object 200 generated by the object display processing unit 9. In this manner, the combined image is displayed on the display unit 19.

  A person skilled in the art who understands the above-described display contents on the screen 20 of the content display device 100 can apply the known technology such as OpenGL (Open Graphics Library) to the book shelf object 200 and each shelf surface 11. Display, rotation of the bookcase object 200 and its display, scroll movement of the shelf surface 11 and its display, and the like can be realized. Therefore, a description of a specific data processing method and management method in each processing unit and each management unit for realizing these displays is omitted.

  The display unit 19 can be composed of a liquid crystal panel or the like.

  As described above, in the content display device 100 of the present embodiment, when changing the display area in the bookcase object 200 to be displayed on the screen 20, the position of the viewpoint is not changed, but the position of the viewpoint is left as it is. Rotate or move the shelf surface 11 of the bookshelf object 200. Thereby, the area visible from the virtual viewpoint is changed, and the position of the display area 14 displayed on the screen 20 is changed.

[Display of bookshelf objects]
Next, a display method of the bookshelf object 200 on the screen 20 of the content display device 100 will be described. FIG. 3 is a diagram illustrating a screen display example in the content display apparatus 100.

  In the present embodiment, different categories are defined on the four shelf surfaces 11, and thumbnail images 12 of electronic books belonging to the defined categories are arranged on the shelf surface 11. There are no restrictions on the categories, but in the present embodiment, there are four categories of “unread / recommended”, “recently read books”, “favorites”, and “subscriptions”, and the four categories of the shelf surface 11 are defined respectively. ing.

  As described above, since the content classified into the common category for each side surface 11 is included, the management of the content is facilitated, and the search for the target content is facilitated. Further, as described above, the content display device 100 can change the display area 14 of the bookcase object 200 on which the plurality of images 12 are arranged by scrolling or rotating, so that it is easy to see the images 12 of many contents. It is. Therefore, the user can visually search various books as if they were in a bookstore.

  As described above, the shape of the bookcase object 200 is not limited to a rectangular parallelepiped, and may be other polygonal columns. Therefore, the number of the shelf surfaces 11 is not limited to four, and the types of categories that define each shelf surface 11 are not limited to four.

  In the content display device 100, as shown in FIG. 3, when the display area is not moved by a user operation, the front portion of the bookcase object 200 is displayed on the screen 20. Here, the shelf 13 and the thumbnail images 12 of the books are displayed on the screen 20 so that the thumbnail images 12 are placed on the shelf 13.

  In the upper part of the screen 20, an indicator indicating the category of each shelf surface 11 of the bookcase object 200 is provided so that the category of the currently displayed shelf surface 11 can be seen.

  For example, in FIG. 3, the “unread / recommended” indicator is lit, indicating that the category of the shelf surface 11 currently displayed is “unread / recommended”. This indicator also serves as the shelf surface selection button 17, and the displayed shelf surface 11 is switched by selecting the indicator of the category to be displayed. In addition, operation input buttons 18 for executing each function of the content display device 100 are displayed at the bottom of the screen 20.

  In addition, the screen 20 is displayed in a state in which the shelf surface 11 is viewed from slightly above. Therefore, it is displayed on the screen 20 so that the upper surface of the shelf 13 provided on the shelf surface 11 can be seen. Further, when the shelf surface 11 is looked down from the upper side in the real world, the ratio of the upper surface that can be seen as the shelf 13 arranged on the lower side increases, but the shelf 13 arranged on the lower side similarly in the bookcase object 200. It is displayed so that the area of the upper surface becomes larger.

  Here, a method for changing the display content of the screen 20 by moving the bookcase object 200 in the virtual three-dimensional space will be described.

In the content display device 100, the length in the longitudinal direction of each shelf surface 11 of the bookcase object 200 exceeds the length that can be displayed on the screen 20 at a time. Therefore, in the shelf surface 11 to be displayed, the area actually displayed on the screen 20 is a part of the shelf surface 11 as shown in FIG.

  That is, in FIG. 2, the display area 14 surrounded by a broken line frame is an area that is actually displayed on the screen 20, and the other areas are not displayed on the screen 20. Therefore, the shelf surface 11 displayed on the screen 20 is moved in the longitudinal direction to change the display region 14, and the region that has not been displayed so far is displayed on the screen 20. Thereby, the image 12 of the book arrange | positioned in the area | region which was not displayed can be seen.

  In the content display device 100, when the user performs a flick operation in the direction in which the user wants to move on the touch panel (input unit 1), the shelf surface 11 is scrolled in the same direction as the flicked direction and has not been displayed so far. The displayed area is displayed. At this time, the movement distance (number of rows) of the shelf surface 11 is determined according to the flick speed, and the shelf surface 11 is moved based on the determination.

  The extent to which the shelf surface 11 is moved with respect to the flick speed is not limited as long as a part of the image 12 displayed on the screen 20 is not interrupted after the shelf surface 11 is moved. May be determined as appropriate. For example, as described above, the distance for scrolling may be obtained using a parameter for determining mobility prepared in advance.

  FIG. 4 is a diagram for explaining a state when the display area 14 of the bookcase object 200 is moved. FIG. 4A shows the shelf surface 11 before the movement. When flicking is performed in the direction of arrow A, the shelf surface 11 is moved upward and displayed below the shelf surface 11. The region 14 is moved ((b) of FIG. 4). Thereafter, the movement of the display area 14 stops below the shelf surface 11, and another image 12 is displayed so as not to be interrupted ((c) of FIG. 4).

  The movement of the shelf surface 11 in the longitudinal (vertical) direction is controlled independently within the range of each shelf surface 11. That is, the shelf surface 11 scrolled in the vertical direction is only the shelf surface 11 displayed on the screen 20 at the time of operation.

  For example, when the uppermost part of each shelf surface 11 is designated as the display area 14, a flick operation is performed while any one of the shelf surfaces 11 is displayed, and the display area 14 on the shelf surface 11 is moved downward. At this time, the shelf surface 11 to which the display region 14 is moved is only the shelf surface 11 being operated, and the display region 14 is not moved on the other shelf surface 11 and remains at the top. Therefore, even if the bookcase object 200 is rotated and another shelf surface 11 is displayed after the display area 14 is moved, the state when the shelf surface 11 was previously viewed on the other shelf surface 11. Is maintained.

  As an example, the book shelf object 200 is rotated with the top of the shelf surface 11 corresponding to the “favorite” category displayed, and moved to the “unread / recommended” shelf surface 11. Assume that the bottom part is displayed. At this time, when the bookcase object 200 is rotated again to return to the “favorite” shelf surface 11, if the display region 14 is moved also on the shelf surface 11, the user performs a scroll operation again to display the display region 14. 14 has to be moved, which is inconvenient for the user.

  However, in the content display device 100, when the bookshelf object 200 is rotated and moved to another shelf surface 11, the state of the shelf surface 11 that has been viewed before is displayed, so that it does not save the user time.

(Rotating bookcase objects)
In the content display device 100, the bookcase object 200 can be rotated in the virtual three-dimensional space in the screen 20 with the central axis X as a rotation axis by a user input operation. By rotating the bookshelf object 200, the shelf surface 11 displayed on the front, that is, the display target can be changed.

  The content display device 100 according to the present embodiment rotates the bookshelf object 200 by performing a flick operation on the touch panel (input unit 1) in a direction substantially orthogonal to the rotation axis (horizontal direction on the screen 20). It has become. By rotating the bookshelf object 200 in this way, the shelf surface 11 that comes to the front, that is, the display target can be changed.

  Specifically, the book shelf object 200 rotates in the same direction as the flicked direction by the flick operation, and the adjacent shelf surface 11 or the adjacent shelf surface 11 comes to the front and is displayed on the screen 20. ing.

  FIG. 5 is a diagram for explaining a state when the bookcase object 200 is rotated. FIG. 5A shows the bookcase object 200 before rotation. When a flick operation is performed in the direction of arrow B, the shelf surface 11a is rotated rightward (FIG. 5B). ), The front of the adjacent shelf surface 11b is displayed ((c) of FIG. 5). Accordingly, the image 12b of the book belonging to another category is displayed from the image 12a of the book belonging to a certain category, so that the image 12b can be selected. This rotational movement will be further described with reference to FIG.

  FIG. 6 is a developed view of the bookshelf object 200 for explanation. However, the top and bottom surfaces are not shown in FIG.

  FIG. 6A shows the book shelf object 200 before rotation, and is a state in which the front surface of the shelf surface 11 a corresponding to the “unread / recommended” category is displayed on the screen 20. In this state, when it is desired to display the shelf surface 11b corresponding to the category of “recently read books” adjacent to the shelf surface 11a, the shelf surface 11b is viewed in the direction opposite to the shelf surface 11b (in the direction of arrow B). Perform a flick operation. As a result, the bookcase object 200 rotates so that the shelf surface 11a moves in the direction of arrow B and the shelf surface 11b comes to the front, so that the display area 14 moves to the shelf surface 11b, and the shelf surface 11b is displayed on the screen. (FIG. 6B).

  Note that the rotation of the bookshelf object 200 is not limited to one rotation, and the movement distance of the shelf surface 11, that is, the number of rotations is determined according to the flick speed, and the shelf surface 11 is rotated based on the determination. That's fine. For example, when the flick speed is slow, the adjacent shelf surface 11 may be displayed by moving by one surface, and when the flick speed is fast, two adjacent shelf surfaces 11, that is, before rotating. The shelf surface 11 located on the opposite side of the displayed shelf surface 11 may be displayed.

  How much the shelf surface 11 is rotated with respect to the speed of the flick is determined based on the shelf surface 11 to be displayed by the rotational movement without partial interruption of the image 12 displayed on the screen 20 after the shelf surface 11 is rotated. It is not limited as long as the surface is parallel to the surface, and the manufacturer may determine as appropriate. For example, as described above, the number of surfaces to be rotationally moved may be obtained using a parameter for determining mobility prepared in advance.

  Further, the above-described scroll movement or rotation movement operation is not limited to the flick operation, and for example, a drag operation can be used. The drag operation is an operation of moving the user's finger in an arbitrary direction while keeping the finger touching the touch panel. The shelf surface 11 or area to be displayed by rotating the bookshelf object 200 or scrolling the shelf surface 11 by a drag operation and then releasing the finger from the touch panel when the image 12 of the desired book is displayed on the screen. Can be changed.

  For example, when the drag operation ends in the middle of the rotation to the adjacent shelf surface 11, it is determined whether to further rotate or return the rotation according to the rotation angle of the bookcase object 200 at that time. The shelf surface 11 can be displayed. In addition, when a part of the image 12 displayed on the screen 20 when the drag operation ends during scroll movement in the shelf surface 11 is interrupted, the shelf surface 11 is scrolled up or down to move the image 12. Can be displayed without missing.

  In addition to the method of changing the shelf surface 11 to be displayed, the shelf surface 11 to be displayed can be changed by operating the shelf surface selection button 17 that can directly indicate which shelf surface 11 is to be displayed. The shelf surface selection button 17 is displayed as an object in the upper part of the screen 20, and allows a button selection operation to be input by a touch panel. Even in this case, the screen 20 displays a state where the bookcase object 200 rotates until the selected shelf surface 11 is displayed. The rotation direction at this time can be determined by the previous user operation, the rotation angle, the setting by the manufacturer, and the like.

  As described above, the operation of operating the bookcase object 200 and the shelf surface 11 displayed on the screen 20 is reminiscent of the operation of the rotary bookcase placed in a bookstore or the like. Therefore, even a person who contacts the content display device 100 for the first time or a person unfamiliar with the operation of the device can easily understand the operation method of the content display device 100. That is, it can be said that the user interface is easy to operate for the user.

  Note that, unlike a rotary bookcase placed in a bookstore or the like, for example, when looking at the lower side of the shelf surface 11, the shelf surface 11 itself being viewed can be moved upward only by the shelf surface 11. . Further, the bookcase object 200 can be rotated in this state. Accordingly, when the bookcase object 200 is rotated after viewing a different height position of a certain shelf surface 11, the work is not performed on the other shelf surface 11 without returning the viewpoint to the original height position. You can see the height position.

[Other animations]
In the content display device 100 of the present embodiment, in addition to the rotation of the bookcase object 200 or the animation of scrolling the shelf surface 11, for example, the shelf surface 11 can be enlarged or reduced, or the bookcase object 200 can be made transparent.

(Enlarged / reduced display)
The content display device 100 is configured to be able to change the number of images 12 to be displayed on the screen 20 by adjusting the size of the shelf surface 11 while the shelf surface 11 is displayed on the screen 20.

  FIG. 7 is a diagram illustrating an example of a display pattern of the thumbnail image 12 displayed on the screen 20. FIG. 7A shows a state where 20 thumbnail images 12 are displayed, and FIG. 7B shows a state where 28 thumbnail images 12 are displayed.

  When the shelf surface 11 is displayed larger, each thumbnail image 12 becomes easier to see, but the number of thumbnail images 12 that can be displayed on the screen 20 at a time (correlated with the number of shelves 13 that can be displayed at a time) decreases. On the other hand, when the shelf surface 11 is displayed smaller, many thumbnail images 12 can be displayed at a time. Thus, in the content display device 100, the scale ratio of the shelf surface 11 can be changed as necessary.

  The number of thumbnail images 12 displayed on the screen 20 can be changed by a user input operation. Specifically, by performing a pinch-out operation on the touch panel, the shelf surface 11 is enlarged and each thumbnail image 12 is displayed in a large size. On the other hand, by performing a pinch-in operation on the touch panel, the shelf surface 11 is reduced and each thumbnail image 12 is displayed small.

  Here, the pinch-out operation is an operation in which two fingers of the user are simultaneously brought into contact with the operation surface and the two fingers are opened as they are. The pinch-in operation is an operation in which two fingers of a user are simultaneously brought into contact with the operation surface and the two fingers are closed as they are.

(Transparency treatment)
In the content display device, when the rotation of the bookcase object 200 and the scroll movement of the shelf surface 11 are displayed on the screen 20, it is possible to perform a process of making part of the shelf surface 11 and the thumbnail image 12 translucent.

  For example, when the transparency of the thumbnail image 12 on the displayed shelf surface 11 is 0%, the adjacent shelf surface 11 and the thumbnail image 12 pasted on these are not displayed on the screen 20.

  On the other hand, when the transparency of the shelf surface 11 is increased, the thumbnail image 12 arranged on the adjacent shelf surface 11 can be seen through even if a certain shelf surface 11 is in front. Furthermore, when the transparency of the thumbnail image 12 is increased, the image 12 arranged on the adjacent shelf surface 11 becomes more visible.

  In this way, by making the shelf surface 11 partially translucent or changing the degree of translucency, the user can feel that he is operating a three-dimensional object. Further, by displaying the adjacent shelf surface 11, it is possible to determine what category the shelf surface 11 is adjacent to, or what book (thumbnail image) is placed on the shelf surface 11. You can find out the target book more easily.

[Display subscription shelf]
Next, a display method of the shelf surface 11 whose category is “regular subscription” will be described with reference to FIG.

  FIG. 8 is a diagram illustrating a display state of the screen 20 displaying the shelf surface 11 whose category is “subscription”. The shelf surface 11 of the regular subscription is a shelf surface 11 that manages periodicals such as a weekly magazine or a monthly magazine together with a back number.

  As shown in FIG. 8A, on the shelf surface 11 of the regular subscription, thumbnail images 12 are arranged in a line in the vertical direction on the left side of the shelf surface 11. These are thumbnail images 12 of the latest issue of each magazine that is subscribed to each, and are images such that the latest issue is placed in the magazine rack. That is, it resembles a state where magazine racks of magazines are arranged in the vertical direction in an actual bookcase.

  Next to the thumbnail image 12, information 15 of the magazine that is subscribed regularly, such as the name of the magazine and the number of the latest issue, is displayed as text. Further, a selection button 16 for displaying the back number of the magazine is provided next to the magazine.

  FIG. 8B is a diagram showing the screen 20 when the selection number 16 of the subscription magazine on the screen 20 shown in FIG. 8A is selected and its back numbers are displayed as a list. .

  When an input operation is performed on the selection button 16 for displaying the back number, the display of the magazine racks other than the selected magazine rack disappears, and the display of the selected magazine rack moves to the top of the screen 20. Then, the thumbnail images 12 'of the respective back numbers are arranged on the lower side, and a transition is made to a state in which the back numbers of the magazines are displayed as a list. The user can select the desired back number from these.

  This is similar to the actual operation of opening the magazine rack of the bookshelf, taking out each back number, and selecting the back number you want to read from it. Therefore, even if the total number of magazines reaches several hundreds, the user can easily select a target magazine.

(Program and recording medium)
Finally, each unit included in the content display device 100 may be configured by hardware logic. Moreover, you may implement | achieve by software using CPU as follows.

  That is, the content display device 100 includes a CPU that executes instructions of a program that realizes each function, a ROM that stores the program, a RAM that expands the program into an executable format, and a memory that stores the program and various data. And other storage devices (recording media). With this configuration, the object of the present invention can be achieved by a predetermined recording medium.

  The recording medium only needs to record the program code (execution format program, intermediate code program, source program) of the program of the content display apparatus 100, which is software that realizes the above-described functions, in a computer-readable manner. This recording medium is supplied to the content display device 100. Thereby, the content display device 100 (or CPU or MPU) as a computer may read and execute the program code recorded on the supplied recording medium.

  The recording medium that supplies the program code to the content display device 100 is not limited to a specific structure or type. That is, the recording medium includes, for example, a tape system such as a magnetic tape or a cassette tape, a magnetic disk such as a floppy (registered trademark) disk / hard disk, or an optical disk such as a CD-ROM / MO / MD / DVD / CD-R. System, a card system such as an IC card (including a memory card) / optical card, or a semiconductor memory system such as a mask ROM / EPROM / EEPROM / flash ROM.

  Further, even if the content display device 100 is configured to be connectable to a communication network, the object of the present invention can be achieved. In this case, the program code is supplied to the content display device 100 via the communication network. The communication network is not limited to a specific type or form as long as it can supply program codes to the content display device 100. For example, it may be the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, and the like.

  The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type. For example, even with wired lines such as IEEE 1394, USB, power line carrier, cable TV line, telephone line, ADSL (Asymmetric Digital Subscriber Line) line, infrared rays such as IrDA and remote control, Bluetooth (registered trademark), 802.11 wireless, HDR, mobile phone It can also be used by radio such as a telephone network, a satellite line, and a terrestrial digital network.

  In the following embodiment, parameters for calculating the mobility when the display area is moved by a flick operation are examined. This examination was performed by the user evaluating the comfort of the flick operation in the mobility calculated from the parameters of a plurality of patterns.

  In the following embodiments, “strong flick” or “weak flick” and expressions representing the strength of the flick are used, which indicate the speed at the time of the flick operation. That is, “strong flick” means a fast flick and “weak flick” means a slow flick. For the flicking speed (strength), the value of the argument velocityX of the onFling method called by the OnGuestListener interface was used.

[Example 1: Horizontal flick evaluation experiment]
First, in order to rotate the bookshelf object, the optimum parameters for the horizontal flick were evaluated. The optimum parameters for the horizontal flick were obtained from the following three types of experiments.

(Example 1-1: Investigation of the maximum number of rotating surfaces with a strong flick)
In Example 1-1, when rotating a bookshelf object, it was investigated how many strong flicks the user felt comfortable.

  Specifically, when rotating a bookshelf object by a flick operation, the number of rotation surfaces when a strong flick (speed of 3000 (pixel / sec) or more) is changed, and the comfort of the operation is set to 5 by seven subjects. A grade and ranking was performed. The five-level evaluation is an evaluation that “5” is the most comfortable, and the evaluation becomes lower as the value decreases to “1”.

  The bookcase object is a rectangular parallelepiped having four sides, and the rotation time is not included in the evaluation. The flicking operation was performed with the left hand of the terminal and the index finger of the right hand. Four parameters shown in FIG. 9A are prepared as parameters for determining the number of rotation surfaces, and the frame rate is set to 30 fps. (A) of FIG. 9 is a table | surface which shows the rotation surface number and rotation time in each parameter when carrying out a strong flick.

  As a result, as shown in FIG. 9B and FIG. 9C, the parameter 2 that rotates in two planes with a strong flick is the highest in both evaluation and ranking, and there is little variation for each subject. (B) in FIG. 9 shows the average value (left-filled bar) and ranking (right hatched bar) of the five-stage evaluation for each parameter by the subject, and (c) in FIG. The variance values of the five-step evaluation (left filled bar) and the rank (right hatched bar) by the subject are shown.

(Example 1-2: Investigation of speed threshold in strong flick and weak flick)
In Example 1-2, when the same rectangular parallelepiped bookshelf object as in Example 1-1 was rotated, the threshold of speed at which the user felt comfortable with strong flick and weak flick was investigated.

  Specifically, when rotating a bookshelf object by a flick operation, the threshold of the speed when performing a strong flick that rotates two faces and a weak flick that rotates one face is changed, and six subjects examine the comfort of operation. A five-step evaluation and ranking was performed. The five-level evaluation is an evaluation that “5” is the most comfortable, and the evaluation becomes lower as the value decreases to “1”.

  The rotation time was not included in the evaluation. The flicking operation was performed with the left hand of the terminal and the index finger of the right hand. Four types of parameters shown in FIG. 10A are prepared for determining the threshold value (pixel / sec) of the strong flick and weak flick speeds, the frame rate is 30 fps, the rotation time is 0.67 (s) on one side, Two surfaces were set to 1 (s). (A) of FIG. 10 is a table | surface which shows the threshold value of the speed of the strong flick and weak flick in each parameter.

  As a result, as shown in (b) of FIG. 10 and (c) of FIG. 10, the evaluation of parameter 2 was high for the threshold values of the strong flick and weak flick velocities. (B) in FIG. 10 shows the average value (left filled bar) and rank (right hatched bar) of the five-step evaluation for each parameter by the subject, and (c) in FIG. The variance values of the five-step evaluation (left filled bar) and the rank (right hatched bar) by the subject are shown.

(Example 1-3: Investigation of rotation animation time)
In Example 1-3, the rotation animation time that the user feels comfortable when rotating the same cuboid bookcase object as in Example 1-1 was investigated.

  Specifically, when the bookshelf object was rotated by a flick operation, the animation time was changed, and six subjects evaluated and ranked the comfort of the operation. The five-level evaluation is an evaluation that “5” is the most comfortable, and the evaluation becomes lower as the value decreases to “1”.

  The flick operation was performed with the terminal held by the left hand and the index finger of the right hand. The nine parameters shown in FIG. 11A are prepared as parameters for determining the animation time, the frame rate is 30 fps, the two sides rotate with a strong flick, and the threshold of the speed of the strong flick and the weak flick is 1900 (pixel / sec). . (A) of FIG. 11 is a table | surface which shows the relationship between animation time and a parameter number.

  As a result, as shown in FIG. 11 (b) and FIG. 11 (c), the time when rotating on one surface and the time when rotating on two surfaces were both highly evaluated for 1 second. . (B) of FIG. 11 shows the average value (left filled bar) and ranking (right hatched bar) of the five-step evaluation for each parameter by the test subject, and (c) of FIG. 11 shows the rotation of one surface. It is a figure which shows the average value of evaluation of time (s) and rotation time (s) of 2 surfaces.

(Example 1-4: Investigation of rotation animation time)
In Example 1-4, the rotation animation time at which the user feels more comfortable than in Example 1-3 was investigated.

  Specifically, as in Example 1-3, when rotating a bookshelf object by a flick operation, the animation time was changed, and five subjects were evaluated and ranked with respect to the comfort of operation by seven subjects. . The five-level evaluation is an evaluation that “5” is the most comfortable, and the evaluation becomes lower as the value decreases to “1”.

  The flick operation was performed with the terminal held by the left hand and the index finger of the right hand. The parameters for determining the animation time are prepared in six types as shown in FIG. 12A, the frame rate is 30 fps, the strong flick is rotated in two planes, the threshold of the speed of the strong flick and the weak flick is 1900 (pixel / sec). . (A) of FIG. 12 is a table | surface which shows the relationship between animation time and a parameter number.

  Parameters 5 and 6 were obtained by linearly changing the rotation time depending on the strength of the flick. The graph of FIG. 12B shows the relationship between the flick strength and the rotation time in the parameter 5, the line 32 shows the relationship between the rotation time and the flick strength at the time of one-plane rotation, and the line 33 shows 2 The relationship between the rotation time and the flick strength during surface rotation is shown.

  As a result, as shown in FIG. 12C, the time for rotating one surface is 1.0 to 0.5 seconds, and the time for rotating two surfaces is 1.0 to 0.7. The evaluation of the parameter 5 that changes linearly with the second and the strength of the flick was high. (C) of FIG. 12 shows the average value (left filled bar) and variance value (right hatched bar) of the five-step evaluation for each parameter by the subject.

  From the above results, the user feels comfortable in the horizontal flick is the maximum two-plane rotation in the strong flick, and the threshold value of the speed of the strong flick (two-plane rotation) and the weak flick (one-plane rotation) is 1900 ( pixel / sec), and the rotation time linearly changes depending on the flick strength. FIG. 13 is a graph showing the relationship between the flick strength, the number of rotation surfaces, and the rotation time. In FIG. 13, a line 30 represents the relationship between the flick strength and the rotation time during one-plane rotation, a line 31 represents the relationship between the flick strength and the rotation time during two-plane rotation, and a line segment C represents a threshold value. Indicates.

[Example 2: Vertical flick evaluation experiment]
Next, the optimum parameters for the vertical flick to find the target book comfortably from the bookcase objects were evaluated. The optimum parameters for the vertical flick were obtained from the following four experiments.

(Example 2-1)
In Example 2-1, nine parameters for vertical flicks were prepared, and the parameters that the user felt comfortable were evaluated in five stages as in Example 1.

  Specifically, seven subjects performed the comfort of operation when 100 books were placed on a bookcase object and scrolled by a flick operation to search for a target book. The arrangement of the books displayed on the screen was three horizontal and three vertical, and the flick operation was performed with the left hand of the terminal and the index finger of the right hand.

  Three parameters were prepared for initial speed and damping rate. The initial speed was 0.00252v for the slow speed, 0.0042v for the medium speed, and 0.00588v for the fast speed. “V” is the flick speed (pixel / sec). The attenuation rate is determined by multiplying the frame rate by the attenuation rate. The low rate is 0.9, the medium rate is 0.7, and the slow rate is 0.5. The frame rate is not constant.

  As a result, as shown in FIG. 14, the initial speed and the damping rate were the highest when both were moderate. (A) of FIG. 14 is a table showing the average value of the five-stage evaluation for each parameter by the subject, and (b) of FIG. 14 is a diagram showing the average value of the five-stage evaluation for each parameter by the subject. It is.

(Example 2-2)
In Example 2-2, the same nine parameters as in Example 2-1 were prepared, the time until the user found the target book was measured, and the parameters that felt comfortable were evaluated in five levels.

  Specifically, about 100 books are placed on the bookshelf object and scrolled by flick operation to search for the target book to be placed on the 20th of the 34th row, and the comfort of the operation Performed by the subject. The arrangement of the books displayed on the screen was three horizontal and three vertical, and the flick operation was performed with the left hand of the terminal and the index finger of the right hand. The frame rate is not constant.

  As a result, as shown in FIG. 15, the evaluation was high in the three parameters of (initial speed, damping rate) (medium, medium), (slow, high), and (speed, high). (A) in FIG. 15 is a table showing the average value of the five-level evaluation for each parameter by the subject, and (b) in FIG. 15 shows the time taken for the subject to find the target book for each parameter. (C) of FIG. 15 is a diagram showing an average value of a five-step evaluation for each parameter by a subject.

(Example 2-3)
In Example 2-3, the three parameters that were highly evaluated in Example 2-2 were prepared, the time until the user found the target book was measured, and the parameters that felt comfortable were evaluated in five levels.

  Specifically, about 100 books are placed on the bookshelf object and scrolled by flick operation to search for the target book to be placed on the 20th of the 34th row, and the comfort of the operation Performed by the subject. The arrangement of the books displayed on the screen was three horizontal and three vertical, and the flick operation was performed with the left hand of the terminal and the index finger of the right hand. The frame rate is not constant.

  The numerical values of the parameters were converted from the initial speed and attenuation rate into the number of moving steps and the number of frames required for moving. As the conversion method, the actual animation was visually evaluated and set to the closest value. Specifically, in parameter 1, the number of movement stages is 0.00245v, and the number of frames required for movement is 15 + 0.002v. In parameter 2, the number of moving stages is 0.00065v, and the number of frames required for moving is 7 + 0.001v. In parameter 3, the number of moving stages is 0.00145v, and the number of frames required for moving is 9 + 0.001v. “V” is the flick speed (pixel / sec).

  As a result, as shown in FIG. 16, the evaluation of the subject with respect to the parameter 1 was the highest, and the search time for the book was the shortest. FIG. 16 (a) is a table showing an average value of the time taken to find the target book and a five-level evaluation of each parameter by the subject, and FIG. 16 (b) shows the target book. It is the graph which showed the average value (left black bar) of time taken until it finds, and the five-step evaluation (bar of the right slanting line) in each parameter by a subject.

(Example 2-4)
In Example 2-4, among the three parameters used in Example 2-3, the number of frames required for movement is converted into the time required for movement, and the time until the user finds the target book is measured. The parameter which is felt to be 5 was evaluated.

  Specifically, about 100 books are placed on the bookshelf object and scrolled by flick operation to search for the target book to be placed on the 18th row out of 25 rows, and the comfort of the operation is 7 people. Performed by the subject. The arrangement of the books displayed on the screen was 4 horizontal and 5 vertical, and the flicking operation was performed by holding the terminal with the left hand and the index finger of the right hand. The frame rate was 30 fps.

  The numerical value of the parameter was converted to the time required for movement by fixing the number of frames required for movement in the parameters used in Example 2-3 to a frame rate of 30 fps. Specifically, in parameter 1, the number of movement stages is 0.00065v, and the time (s) required for movement is 0.23 + 0.000033v. In parameter 2, the number of movement stages is 0.00245v, and the time (s) required for movement is 0.5 + 0.000067v. In parameter 3, the number of moving stages is 0.00145v, and the time (s) required for moving is 0.3 + 0.000033v. “V” is the flick speed (pixel / sec).

  As a result, as shown in FIG. 17, the test subject's evaluation for parameter 2 was the highest, and the book search time was also the shortest. (A) of FIG. 17 is a table showing an average value of time taken to find a target book and a five-level evaluation by each parameter by a subject, and (b) of FIG. 17 shows a target book. It is the graph which showed the average value (left black bar) of time taken until it finds, and the five-step evaluation (bar of the right slanting line) in each parameter by a subject. FIG. 17C is a graph showing the relationship between the movement time and the number of movement stages depending on the flicking speed of the parameter 2, in which the line 34 is 4000 (pixel / sec) and the line 35 is 3000 (pixel / pixel). sec), line 36 is 2000 (pixel / sec), line 37 is 1000 (pixel / sec), and line 38 is 500 (pixel / sec).
