Each functional block shown here is realized by a program loaded into memory from a CPU, memory, recording medium, etc. of an arbitrary computer in terms of hardware components, but here, functions realized by their cooperation Draw a block. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

The operation reception unit 102 receives a signal indicating the content of the operation performed on the information processing apparatus 10 by the user from the operation means such as the operation unit 70 and the front touchpad 21 described above. When the operation performed by the user requests acquisition of electronic data of a new content, the content acquisition unit 104 receives information on the requested content, the content providing server of the acquisition destination, etc. Receive from. Then, electronic data of the corresponding content is acquired via the communication unit 106. The operation method, communication establishment, and data transmission processing procedures performed here may be the same as those performed when general content data is downloaded. The acquired content data is stored in the content data storage unit 108 in association with the identification information.

The selection screen control unit 110 represents each content as an object displayed on a display shelf in the virtual space, accepts operations such as content selection, rearrangement order change, orientation change, and clustering from the user, and displays them appropriately. Update. The selection screen control unit 110 includes an object image generation unit 112 that generates image data of an object corresponding to each content, an object image storage unit 114 that stores image data of the generated object, and an arrangement that manages the arrangement of objects on the display shelf The management unit 116 includes an arrangement information storage unit 118 that stores the latest information related to the arrangement of objects, and a selection screen generation unit 120 that generates a content selection screen in response to a user operation.

The object image generation unit 112 generates an image of an object representing each of the contents stored in the content data storage unit 108, and stores the data in the object image storage unit 114. For example, when the content is an electronic book, texture data of the surface corresponding to the cover, back cover, and back cover of the three-dimensional object of the book is generated for each book. Further, the size of the object may be changed according to the category of the book. If the cover image is provided together with the content data, it may be stored in the object image storage unit 114 and used as it is.

If the content is video or music, an image of the object is generated as a package of DVD (Digital Versatile Disc) or CD (Comact Disc). The shape of the object is not limited to these, but it is desirable that the object has a three-dimensional shape that gives a sense of presence similar to that selected and rearranged from a display shelf in real space. In addition, by using objects having different widths such as the front cover and the back cover, the width necessary for the arrangement can be adjusted, and the impression related to the unity when the cluster is formed can be changed. The object image generation unit 112 generates object image data of the content every time new content data is stored in the content data storage unit 108 or when it is first displayed on the content selection screen.

When the user performs an operation to change the arrangement of the object on the content selection screen, the arrangement management unit 116 acquires information to that effect from the operation reception unit 102. Then, the information related to the arrangement stored in the arrangement information storage unit 118 is updated. Here, the “information related to arrangement” includes the order of arrangement of the objects on the display shelf, the direction of the objects, and whether or not the objects are clustered.

The selection screen generation unit 120 uses the data of the object image stored in the object image storage unit 114 and based on the information related to the arrangement stored in the arrangement information storage unit 118, the virtual image obtained by displaying each object on the display shelf. Generate a content selection screen that represents the world. When the user performs an operation for starting display of the selection screen, the selection screen generation unit 120 acquires information to that effect from the operation reception unit 102 and displays the selection screen. In addition, when an operation for moving or changing the direction of an object is performed, the selection screen is updated to reflect the operation. At this time, not only the object to be moved, but also the formation and release of the cluster and the display are changed depending on the relationship with the position of the movement destination and the nearby object. Reference and update information.

When the user performs an operation for selecting a certain content on the content selection screen, the content display screen generation unit 122 reads the data of the content from the content data storage unit 108 and generates the display screen by decoding it. . A general content display technique can be applied to this process. When video or music is selected as content, stereo sound is also played. The display screen control unit 124 controls the output of the content selection screen generated by the selection screen generation unit 120 and the content display screen generated by the content display screen generation unit 122 at a timing according to the output format of the display device 20.

FIG. 5 is a diagram for explaining the basic configuration of the content selection screen displayed in the present embodiment. As described above, the present embodiment has a format in which a selection screen displaying objects representing each content is displayed on the display shelf, and the user selects a content by selecting a desired object from the selection screen. Hereinafter, a description will be given taking a bookshelf format selection screen as an example, with the content as an electronic book and the object as a book. As shown in FIG. 5, the electronic book selection screen is configured by a virtual space in which books (for example,

books

154, 156, 158, 160) are displayed on a shelf board 150 of the bookshelf. Although the figure shows a state where the bookshelf is viewed from the front, it is drawn so that the direction of the line of sight can be changed by three-dimensional graphics. Further, the shelf board 150 may be one stage as shown in the figure, or may be a plurality of stages.

The object image generation unit 112 generates an object model of a book representing each book. When image data corresponding to the front cover, back cover, and back cover of an actual book is included as content data, the image data can be used as texture data as it is. If there is no such data, for example, an image as a template is prepared, and the text data of the title of each book is laid out. As will be described later, when only the image data of the cover is included, the images of the back cover and the back cover are generated using the data.

In order to select a book, the book object (hereinafter sometimes simply referred to as “book”) on the selection screen is displayed in a size sufficient to visually recognize the title. Therefore, as the number of electronic books stored in the content data storage unit 108 increases, it becomes more difficult to display all books at once. Therefore, the viewpoint with respect to the bookshelf can be moved by a user operation. That is, as shown in FIG. 5, all the books are arranged on the shelf board 150, and the display area 152 displayed as the book selection screen can be moved right and left.

For example, the movement of the viewpoint is accepted by the left key 23b / right key 23d of the direction keys 23, the left stick 24a, the right stick 24b, or the like. Alternatively, by placing a finger on the front touchpad 21 and moving the finger to push the bookshelf forward (drag operation) or quickly paying the bookcase (flick operation), the display area 152 is moved so that the bookshelf moves in the corresponding direction. You may move backward. For such operations, a screen scrolling method using a touch panel can be applied. By moving the display area in this manner, it is possible to give the user a feeling similar to selecting a desired book by moving the viewpoint with respect to the actual bookshelf.

Also, as described later, like a real bookshelf, a book can be taken out and moved to another position. In this way, it is possible to determine the arrangement of books according to the user's own criteria regardless of the criteria used for general arrangement rules such as the book category, title, and author name. The relationship between the book determined in this way and its position tends to remain in the user's memory. As a result, even if a large number of books are arranged on a long shelf board, it is easy to reach the desired book only by moving the viewpoint, and it is easier to enter a search key and redisplay the list according to it, and high access efficiency Can be expected.

As shown in FIG. 5, the books on the shelf board 150 are not simply arranged, but the direction and interval can be changed. Specifically, the

books

154 and 156 are placed with the cover facing forward, and the

books

158 and 160 are placed with the spine facing forward. The book 154 indicates that one cluster is formed by placing three books close to each other. Similarly, in the book 158, seven books form one cluster. Thus, a plurality of books in which clusters are formed can be moved together. Further, the clusters are combined so that a new cluster can be generated.

At this time, the cluster with the front cover (book 154) can insert another book between them, and the cluster with the back cover (front 158) cannot be inserted. Change "force". Since the back cover is narrower than the cover, the sense of unity given when a plurality of objects are combined is stronger, and it is easier to understand the strong cohesive force sensuously. Furthermore, as shown by the difference in "binding force", the front-facing cluster has a slight gap between the book and the back-facing cluster, with the book and book in close contact. To do. The cluster with the spine front is always maintained, so it is suitable for a series of books that have a complete volume. On the other hand, a cluster with the front cover in front is suitable for a case where it is desired to move it in a batch but the order is to be changed flexibly.

With the above configuration, you can save space by aligning books in a series, rearranging them in the order you like, allowing you to view the cover of your favorite books, or putting the back cover in front. Can be realized in the same way as an actual bookshelf.

FIG. 6 shows an example of the structure of book data stored in the content data storage unit 108. The book data 200 includes a book ID column 202a, a title column 202b, an author column 202c, a publisher column 202d, a cover data column 202e, and a content data column 202f. The book ID column 202a indicates identification information of an electronic book for which the information processing apparatus 10 holds data. The identification information may be uniquely given inside the information processing apparatus 10 every time the content acquisition unit 104 acquires data, or a product code or the like previously assigned to the data may be used. The title column 202b, the author column 202c, and the publisher column 202d indicate the title, author, and publisher of the electronic book in association with the book ID, respectively. Other information may be further associated as long as it is general bibliographic information attached to the book.

The cover data column 202e and the content data column 202f indicate the file name of the image data of the cover and the file name of the image data of all pages that are the contents of the book in association with the book ID. Instead of the file name, the file itself or the address of the storage area storing the file may be used. Basically, the book data 200 may correspond to various data for each book by the same method as data management in a general electronic book reader terminal.

FIG. 7 shows an example of the structure of book layout management data stored in the layout information storage unit 118. The arrangement management data 204 includes an order column 206a, a book ID column 206b, a cluster ID column 206c, and a direction column 206d. The order of the books counted from the left end or the right end of the virtual bookshelf as shown in FIG. 5 and the identification information of the book represented by the book are associated with the data set shown in the order column 206a and the book ID column 206b. Put it on. The identification information of the book is made to correspond to the identification information shown in the book ID column 202a in FIG. When the order of books is changed by the user, the arrangement management unit 116 changes the order of the book ID column 206b to reflect the change.

Note that the data format of the set of the order column 206a and the book ID column 206b is not limited to this as long as the arrangement order on the bookshelf is clear. You may connect a book with a pointer. The cluster ID column 206c indicates identification information of the cluster if the book belongs to the cluster. When a new cluster is formed, the arrangement management unit 116 gives new identification information that has not been assigned to another cluster to the new cluster.

Since the clustered books are in a continuous state in the bookshelf arrangement, the same value of the cluster identification information in the arrangement management data 204 is continued in a plurality of books. The orientation field 206d alternatively indicates whether the book is placed on the front or the back cover in front. When the placement changes by the user, the arrangement management unit 116 updates the description in the direction column 206d with the changed direction. With such a data structure, the state of the virtual bookshelf can be managed by changing the arrangement order of the books representing the electronic book, whether or not the books belong to the cluster, and the orientation of the books.

FIG. 8 shows an example of a book selection screen displayed on the display device 20. Screen examples 162a and 162b are both display screens corresponding to the display area 152 in the bookshelf in FIG. As shown in the screen example 162a, in addition to the books displayed on the virtual bookshelf in the screen, the GUI of the direction switching button 164 for switching the book orientation, the focus frame 166 indicating the book of interest, and the entire bookshelf A scroll bar 168 indicating the current position of the display area is displayed.

The attention frame 166 is represented by, for example, a rectangle that surrounds a book or cluster closest to the center of the display area as a book of interest. If it does in this way, the book under consideration can be changed in the order corresponding to the arrangement order in a bookshelf by moving a display field to right and left. The book frame touched by the user on the front touch pad 21 or the cluster as a book of interest may be moved. The shape of the frame of interest 166 may be a figure other than a rectangle. Further, instead of the frame, the book itself may be illuminated, the color may be emphasized, or a slight amount may be projected forward or upward. Alternatively, any two or more of them may be combined.

When confirming one book with the frame of interest 166 as a viewing target, either press the ○ button 22b or touch the inside of the frame on the front touchpad 21. As a result, the content display screen generation unit 122 starts decoding and drawing processing of the data of the electronic book represented by the book. Then, the display on the display device 20 is switched to the content display screen.

On the other hand, when the user touches the orientation switching button 164, the placement of the book within the frame of interest 166 is switched bidirectionally between the front / front cover of the spine. At this time, the arrangement management unit 116 updates the direction column 206 d of the arrangement management data stored in the arrangement information storage unit 118. Then, the selection screen generation unit 120 changes the direction of the book object. At this time, the book replacement operation can be expressed by giving a motion that gradually changes the angle of the object. In addition, like the operation of the direction switching button 164 via the front touch pad 21, the switching may be performed by operating the □ button 22d.

When the virtual bookshelf has a width exceeding the display area 152 as shown in FIG. 5, the scroll bar 168 clearly indicates which position of the bookshelf is being displayed. As described above, in the present embodiment, since the order of books is determined by the user replacing the book object, even if the user holds a large number of book data, the desired book can be relied on the memory associated with the position. You can get to it. By displaying the scroll bar 168, even if the display area is moved at high speed without checking the titles one by one, the desired book can be reached efficiently based on the approximate position.

The lower screen example 162b has the same configuration, but the line-of-sight direction is different from the screen example 162a. As shown on the left side of each screen example, during the operation of moving the display area to the right (arrow 164a), the center of the bookshelf in the display area is displayed in a state viewed from the left from the front. That is, on the plane overlooking the bookshelf, the bookshelf is drawn in a line-of-sight direction 166a inclined at a predetermined angle θ (0 <θ <90 °) clockwise from the line of sight from the front. On the other hand, during the operation of moving the display area to the left (arrow 164b), the center of the bookshelf in the display area is displayed in a state viewed from the right side from the front. That is, on the overhead view plane, the bookshelf is drawn in a line-of-sight direction 166b inclined by a predetermined angle θ (0 <θ <90 °) counterclockwise from the line of sight from the front. As a result, a book with a spine on the front can be seen on the screen example 162a and a back cover can be seen on the screen example 162b.

In this way, the display area can be moved left and right with natural changes similar to changes in the field of view due to actual movement of the viewpoint. When the movement operation of the display area is stopped, the viewpoint state at that time may be maintained, or the viewpoint may be moved to the front. Further, during the moving operation, the viewpoint may be moved away from the bookshelf by a predetermined amount so that more books can enter the field of view, and when the moving operation stops, the viewpoint may be approached so that each book can be confirmed in detail.

9 to 15 show transition examples of the book selection screen by user operation. In these figures, it is assumed that the bookshelf is viewed from the front, and each book object is shown as a rectangle, but in reality, a three-dimensional object as shown in FIG. 8 is displayed with the viewpoint changed. And Each book object is numbered so that changes in position can be seen. Furthermore, although the operation means used for each operation is illustrated, the operation means can be variously set according to the initial allocation method, and is not limited to the illustrated one.

First, FIG. 9 shows an example of a screen change when the direction of a book is switched. On the screen 172a, the books “0” to “3” are all placed in this order, with the cover front. A focus frame 166 is shown for the book “1”. When the direction switching button 164 is operated in this state, the book “1” is switched to the screen 172b with the spine cover placed in front. During switching, an animation is displayed so that the direction of the book “1” gradually changes as described above. When the direction switching button 164 is operated in the state of the screen 172b, the cover is turned to the front again and the screen returns to the screen 172a.

10 to 12 show examples of screen changes when the order of books is changed. The initial screen is a screen 172a in FIG. When the R button 26b is pressed in a state where the frame of interest 166 is shown for the book “1” on the screen 172a, the state of the screen 176a in FIG. To do. By this operation, the book “1” is set as the movement target. As a result of the book “1” surfacing, the book “2” displayed on the right side of the book is moved to the left to obtain a screen 176b in which the gap is filled. As a result, since the book “2” is positioned substantially at the center, the frame of interest 166 indicates the book “2”.

The user can move the display area of other books with the direction key 23 or the like while the book “1” is left floating. This operation and display are the same as described above when the book is not lifted. On the screen 176c at that time, the display area moves to the right, that is, the book arrangement itself moves to the left, and the book “4” is located at the approximate center. The position of the “1” book is fixed.

The screen 178a in FIG. 11 is the same as the screen 176c in FIG. 10, and the book “4” is located at the approximate center, so that the frame of attention 166 indicates the book “4”. In this state, when an operation to determine such as pressing the ○ button 22b is performed, the book “1” that has emerged is set to a screen 178b that is lowered so as to be adjacent to the book “4”. By this operation, the movement destination of the book “1” is determined, and the book “4” and the book “1” form a cluster. In order to show that these clusters are formed, these books are arranged at a narrower interval than books that do not form clusters. At this time, the arrangement management unit 116 moves the order of the “1” book next to the “4” book in the arrangement management data, and sets the identification information of the new cluster to the “4” book and the “1” book. Write in the cluster ID column 206c.

The screen 180b in FIG. 12 shows a state where the display area is further moved from the screen 176c in FIG. 10 and a book-to-book gap is positioned at the approximate center. When the display area is moved while the book to be moved is floating, the frame of interest is also displayed in the gap between the book. In this state, when an operation to determine such as pressing the ○ button 22b is performed, a screen 180b in which the book “1” that has been lifted is lowered between the gap, that is, the book “4” and the book “5”. And In this way, when a destination is specified between a book that does not form a cluster, the order of arrangement only changes, and no new cluster is formed. Therefore, the interval between the books is made wider than when the clusters are formed. At this time, the arrangement management unit 116 only moves the order of the “1” book to the next of the “4” book in the arrangement management data.

FIG. 13 shows an example of a screen change when the arrangement order of a plurality of books is changed at once. On the screen 176b of FIG. 10, when the book “1” is surfaced and instead the book “2” is shown in the frame of interest 166 and the R button 26b is further pressed, the “2” book is displayed. The book also has a screen 182a that floats upward. In this way, a plurality of books can be floated by successively specifying the books indicated by the frame of interest. In the case of the figure, the “2” book placed next to the “1” book is levitated, but any book can be added if the display area is moved while the “1” book is levitated. Can be levitated. In addition, the order of books that are surfacing is the order in which they are surfacing.

¡Perform this operation continuously, and when the number of flying books reaches a predetermined number or more, change the direction of the flying books to the front with the spine. Thereby, the number of floating books that can be accommodated in the display area can be increased. The screen 182b shows a state in which books “1” to “5” are continuously levitated, and the spine is in front. A plurality of books levitated at the same time can be moved to the same position in one operation. If an operation for determining, for example, pressing the ○ button 22b is performed in a state where the frame of attention 166 is displayed in the gap between the book “6” and the book “7” on the screen 182b, the gap, that is, the “6” is displayed. A screen 182c is displayed in which the books “1” to “5” that have emerged between the books and the book “7” are lowered.

¡As described above, a cluster can be formed by simultaneously raising a plurality of books. On the

screens

182b and 182c, since a book-to-book gap is designated as the movement destination, a cluster is formed only from the books “1” to “5” that are levitated simultaneously. At this time, the arrangement management unit 116 moves the order of the “1” to “5” books to the next of the “6” books in the arrangement management data, and sets the new cluster identification information to “1” to “5”. Is written in the cluster ID column 206c of the book.

FIG. 14 also shows an example of a change in the screen when the arrangement order of a plurality of books is changed at the same time as in FIG. However, in this case, a book that has already formed a cluster is designated as the destination. The screen 184a shows a state in which the books “6” to “10” are levitated in this order after the clusters “1” to “5” are formed on the screen 182c of FIG. When an operation for determining, such as pressing the ○ button 22b, is performed in a state where the focused frame 166 indicates a cluster of “1” to “5” books, the “6” that has emerged with the same policy as in FIG. ”To“ 10 ”is a screen 184 b that is lowered so as to be adjacent to the cluster of“ 1 ”to“ 5 ”books.

This causes the cluster of books “1” to “5” and the cluster of books “6” to “10” to be combined to form one cluster. In this case, cluster identification information has already been assigned to the books “1” to “5” of the movement destination. Therefore, the arrangement management unit 116 moves the order of the “6” to “10” books to be moved to the next of the “1” to “5” book clusters in the arrangement management data. The identification information of the cluster assigned to the book “5” is written in the cluster ID column 206c of the books “6” to “10”.

As shown in the screen 184a, the screen 184b, etc., when the books forming the cluster are placed on the bookshelf with the back cover as the front, the attention frame 166 is displayed for the entire cluster. As a result, not only the move destination but also the move target can be specified in cluster units. For example, on the screen 184a in FIG. 14, books “6” to “10” are emerging. This state can be realized even if each book is individually levitated as described above, and if all or a part of the books “6” to “10” originally form a cluster, that Can also be realized by bringing them together in a single operation.

In the latter case, when it is determined that the destination cluster is a cluster of “1” to “5”, the arrangement management unit 116 is originally assigned to the books “6” to “10” in the arrangement management data. Discard the cluster identification information. Then, the identification information of the clusters assigned to the books “1” to “5” is written in the cluster ID column 206c of the books “6” to “10”.

FIG. 15 shows an example of a screen change when individual selection is possible when a plurality of books with a spine in front form a cluster. First, on the screen 186a, since the books “1” to “5” are placed with the spine on the front to form a cluster, the attention frame 166 collectively shows the cluster. In this state, when the selection operation is performed by touching the frame of interest 166 on the front touch pad 21 or pressing the ○ button 22b, the intervals between the books “1” to “5” are opened and individual selections are made. Accept. On the screen 186b, the frame of interest 166 shows only the book “2” which is one of the clusters and is located at the approximate center of the display area.

In such a mode, as in the case where no cluster is formed, individual selection is made possible by moving the display area or moving the frame of interest 166 itself. As a result, one book belonging to the cluster can be removed from the cluster or directly selected for browsing. Specifically, the R button 26b is pressed and floated in a state where the frame of attention 166 is shown in one book, and is removed from the cluster by moving it to another position. Further, when a selection operation is performed by further touching the inside of the book with the frame of interest 166 shown or pressing the ○ button 22b, the content display screen of the electronic book corresponding to the book is switched.

The state of the screen 186b enables selection for each book belonging to the cluster, but the cluster information is maintained at this stage. Then, the original state, that is, the state in which the clusters can be selected at once can be restored. Specifically, as shown in the screen 186c, when the frame of attention 166 moves to a book outside the cluster ("7" book in the figure) by moving the display area, the individual selection acceptance is canceled and the cluster is moved to the cluster. The books “1” to “5” to which they belong are brought close to each other. Alternatively, in the state of the screen 186b, an operation to slide the two fingers on the front touchpad 21 so as to reduce the interval in any one of the open “1” to “5” regions (pinch-in operation) Individual selection acceptance may be canceled by performing. A x button 22c or the like may be used.

So far, the description has been made of the aspect in which the book of interest is mainly surrounded by the rectangular frame of interest. However, as described above, the expression technique is not limited as long as the book or space of interest can be distinguished from the others. FIG. 16 shows another example of a technique for expressing a book or space under attention. In this example, as shown in the screen example 188a, the book 290 being noticed is lifted upward from the shelf 292 by a predetermined amount. In this case, the flying height is set to a minute amount smaller than the height of the book so that the book can be distinguished from the book flying as a moving object. When attention is paid to the space between the books in this mode, for example, as shown in a screen example 188b, the interval 294 between the books is increased by increasing the book-to-book spacing. Processing such as book movement and selection may be the same as that for the frame of interest.

Regardless of whether or not the frame of interest is displayed, the book or space under attention may be moved in the horizontal direction using the left key 23b, the right key 23d, or the like. In this case, the screen is scrolled by a predetermined amount in the left direction or the right direction so that the area of the book shelf ahead is within the screen at the point where the target position reaches the left end or the right end of the screen. When the frame of interest is moved by a touch operation using the front touch pad 21, first, the bookshelf is moved in the moving direction of the contact point by a flick operation that quickly pays a finger touched or a drag operation that moves the contact point. Scroll the screen.

At this time, the position of interest may be left at the approximate center of the screen or may move with the bookshelf. In the latter case, when the position of interest reaches the left or right edge of the screen, the relative position with respect to the bookshelf may be changed so that the position of interest remains within the screen, or the position of interest itself may be moved off the screen as it is. And may disappear once. In any case, even if the screen is not scrolled, the position of interest may be directly selected by touching a book or a space between them.

FIG. 17 shows variations of the moving operation that can be realized by the configuration described so far. There are four types of states depending on whether the book to be moved and the book to be moved form a single unit or a cluster, or whether the front is a front cover or a back cover. In the movement operation correspondence table 207 in the figure, the descriptions of “single / cover”, “single / back cover”, “cluster / cover”, and “cluster / back cover” in the movement destination column 208a and the movement target column 208b are as follows: It shows the state of the book designated as the destination or destination. The movement destination column 208a also shows a case where “between books” is designated as the movement destination.

The state column 208c after movement in the movement operation correspondence table 207 indicates the state of the movement target after movement in the form of “order of arrangement at the movement destination / final direction”. First, when a book is specified as a destination and the book is a single unit that does not form a cluster, the orientation of the book to be moved when floating as shown in the first and second rows of the move operation correspondence table 207 Priority is placed, and it arranges in the state adjacent to the right side of the book of the movement destination. At this time, as described above, the book to be moved forms a cluster together with the book to be moved. When the distance between a book and a book is designated as the movement destination, as shown in the fifth row of the movement operation correspondence table 207, the orientation of the book to be moved is adopted as it is and arranged at the designated position. In this case, no clusters other than those formed at the time of floating are formed.

When a book is designated as the destination and the book forms a cluster, the direction of the destination book is prioritized as shown in the third and fourth lines of the movement operation correspondence table 207. When the book at the movement destination has the cover in front, a gap is also provided between the books, and it is allowed to designate this as the movement destination. Therefore, as shown in the third line, any of the start, middle, and end of the destination cluster can be specified. On the other hand, when the book to be moved has the back cover in front, it is additionally arranged at the end of the cluster as shown in the fourth line.

In this way, by providing abundant variations in the state of the book to be moved, the book to be moved, and the book after movement, not only the order of books and how they are displayed, but also the operation method matches the user's preference. The state can be pursued by changing the state of the book.

As shown in FIG. 8, in particular, when changing the viewpoint depending on the moving direction of the display area, it is necessary to prepare texture images for a plurality of surfaces of the object displayed on the content selection screen. A method of simply pasting bibliographic information such as a title on a template image is also conceivable, but here, a realistic virtual world is expressed by drawing an object close to an actual book.

電子 In many cases, electronic book data originally includes cover image data. Therefore, the object image generation unit 112 uses the cover image and the bibliographic information to create a spine and back cover images necessary for drawing the book object. FIG. 18 illustrates an image generated by the object image generation unit 112 using an electronic book as an example.

First, the object image generation unit 112 reads the data of the cover image 190 of the target book and the text data of the title 192 including the volume number among the electronic book data stored in the content data storage unit 108. Next, the representative color is determined from the cover image 190 according to a predetermined rule. For example, a color histogram of a predetermined area such as the entire cover image 190 or the edge is acquired, and the color with the highest count is set as the representative color. Then, the background color of the back cover image 194 and the back cover image 198 is set to the determined representative color.

Also, text data of the title 192 is laid out on the back cover image 194. Since the writing direction of characters on the spine of a general book varies depending on the language, a layout rule is set in advance in association with the language so as to reflect it. In the case of FIG. 18, since the back cover assumes a language in which vertical writing is generally used, such as Japanese, the main part “CCC” of the title is vertical writing. Here, “C” is not intended to be limited to the alphabet, but represents one character. In addition, when it is common that the main title and the direction and position of the volume number such as “14 volumes” are different, the image to be created as shown in FIG.

Alternatively, as a background of the back cover image 194, a predetermined area of the cover image 190 may be copied and used as it is. For example, the center vertically long region 196 in the cover image 190 is used as the background. At this time, by adjusting the lightness and saturation of the copied image to make the color lighter, it is made difficult to recognize the character of the title to be laid out thereon. The back cover image 198 may have only a background color as shown in the figure, or a publishing company logo mark or virtual barcode may be laid out to produce a more authentic appearance.

As described above, according to the present embodiment, various apparent states can be easily applied to one electronic book, such as the order of books in a virtual bookshelf, the orientation of the books, and whether or not a cluster is formed. Can be changed by simple operation. And so that the user can efficiently access the desired book data from a large amount of electronic book data that he / she holds, based on his / her preferences, experience, and interests at that time, The state can be devised. As a result, in addition to information as a list of book data that is held, the book state itself in the virtual world can be information representing know-how related to access efficiency, personal trends, and the like.

Therefore, such information may be shared by a plurality of users. FIG. 19 shows an example of the configuration of an information processing system formed in such a case. In the information processing system 1, an AP (access point) 2 has functions of a wireless access point and a router, and each information processing apparatus 10 is connected to a network 3 such as the Internet via the AP 2 and a modem (not shown). To do.

The information processing apparatus 10 has a wireless communication function, connects to the server 5 on the network 3 via the AP 2, transmits its own data to the server 5, and transmits data of other information processing apparatuses 10 from the server 5. Receive. The information processing apparatus 10 has a communication function based on a wireless LAN (Local Area Network) system and may communicate with the server 5 in the infrastructure mode. However, the information processing apparatus 10 is employed in a mobile phone such as a third generation mobile communication system. You may communicate with the server 5 by a communication system. In this case, since the information processing apparatus 10 communicates with the server 5 via a base station having a wide communication area, the user can use the information processing apparatus 10 even outdoors. In the information processing system 1, the user has a user account for identifying himself / herself, and signs in to the network service provided by the server 5 using the user account.

In such an information processing system 1, the server 5 provides SNS (Social Networking Service). In this SNS, a user of another information processing apparatus 10 can browse a virtual bookshelf created by a user of an information processing apparatus 10 and acquire data related to the arrangement of books. The substance of the data acquired here is information shown in the book ID column 202a, the title column 202b, the cover data column 202e, etc. in the book data 200 shown in FIG. 6, and the arrangement management data 204 shown in FIG. . In this case, the communication unit 106 of FIG. 4 transmits the data created by the own device to the server 5 and receives the data created by the other device from the server 5. As a result, a bookshelf created by another user can be displayed on his / her information processing apparatus 10. Or the image data itself of a bookshelf may be sufficient.

In the bookshelf of other users displayed in this way, it can be seen that the book whose electronic book data has not been acquired by the information processing apparatus 10 is not acquired by making the appearance different from the book whose data has been acquired. To. This structure provides a part of communication such as sharing the interests and preferences of users who created bookshelves, talking about books that have already been acquired, and considering their own purchases based on the impressions of books that have not been acquired. can do. If an unacquired book in the bookshelf is selected, the information processing apparatus 10 may automatically establish data communication with a server that provides an electronic book so that data can be purchased directly. At this time, the bookshelf may be displayed on the screen, and the appearance of the corresponding book may be changed according to the data download.

The above is a mode in which a plurality of users share a bookshelf, but individual electronic books purchased by a plurality of information processing apparatuses by the same user may be aggregated in one bookshelf. In this case, the server 5 stores the book data and the arrangement management data in the storage device in association with the user account. This information is managed for each user account whenever the user purchases an electronic book, regardless of the information processing apparatus used for the purchase. Instead of the server 5, an information management role may be given to one of the information processing apparatuses possessed by the user.

When an operation for displaying a bookshelf is performed in an information processing apparatus 10, data associated with the user account used for sign-in at that time is transmitted to the information processing apparatus 10. Thus, the same bookshelf can be displayed for the same user regardless of the information processing apparatus 10 being operated. When the data of the electronic book selected by the user from the displayed bookshelf is not stored in the information processing apparatus 10 that is being operated, if the data is transmitted from the server 5, which information processing apparatus 10 Can also enjoy purchased e-books with the same operation.

Also, the virtual bookshelf in this embodiment can be used for selling electronic books by displaying them on a web page of a site selling electronic books. In bookstores in the real world, recommended books and new publications are laid out in a conspicuous place, or the arrangements unique to dealers are devised. In this embodiment, the direction and order of books can be easily changed, and a plurality of books can be easily moved together. Therefore, sales can be promoted by the same device as an actual store.

As described above, according to the present embodiment described above, a screen for selecting content provided by electronic data is represented by a virtual world in which objects representing each content are arranged on a display shelf. In addition to starting display of the content body by moving the display area for this display shelf and selecting a desired object, the state of the object can be changed, such as rearranging the objects and changing the orientation of the objects. To. This allows you to place a display shelf that suits your tastes, such as placing a package with your favorite design so that you can see it, or pinching it in a direction that does not take the width so that you can see many objects at once. Each user can create. As a result, it is possible to achieve both improvement in access efficiency considering individual circumstances and preference as the appearance of the selection screen.

Also, when changing the order of arrangement, it is possible to provide a variation in the operation method by allowing multiple objects to be handled as a cluster. By doing in this way, it is possible to select an appropriate operation method according to whether the content is a series item or the user's request. In addition to the pleasure of purchasing and increasing electronic data, you can also enjoy the enjoyment of clustering and arranging on the bookshelf and the pursuit of efficient alignment. Furthermore, by generating texture data of a plurality of surfaces of an object for each content and expressing it as a three-dimensional object, it is possible to give a sense of realism to a general content selection operation performed only with text information.

Furthermore, by providing an SNS that allows other users to see the created display shelf, it is possible to share not only information on the contents owned but also information on how to place and arrange the contents. In addition, by providing a system that allows one book shelf to be shared by multiple devices owned by a single user, the purchased content can be enjoyed by any information processing device, and the arrangement on the display shelf can be shared by multiple information processing devices. The user can easily access the desired content using the memory.

The present invention has been described based on the embodiments. Those skilled in the art will understand that the above-described embodiment is an exemplification, and that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. is there.

For example, in the present embodiment, a description has been mainly given of a mode of displaying a book-shaped object representing an electronic book. In this case, since the object is a polyhedron, the orientation of the object can be switched depending on which surface is the front. On the other hand, the object may not be a polyhedron and may have a flat shape. For example, when the content is music, the album jacket image is textured on the board. The orientation of the plate surface may be switched depending on whether the plate surface is placed in front of the viewpoint or in an oblique direction having a predetermined angle with respect to the viewpoint within a range where the image of the plate surface can be visually recognized. And when it puts diagonally, it treats similarly to the case where a spine is made into the front in this Embodiment. Thereby, the same effect as this embodiment can be obtained. Moreover, it is not necessary to prepare an image corresponding to the spine regardless of the content.

Further, in the cloud computing environment, the function of the selection screen control unit 110 in FIG. 4 may be provided as a cloud service. In this case, when the user performs an operation related to selection or rearrangement of an object such as a book in the information processing apparatus 10 operated by the user, the server that has acquired the contents of the operation through the network reflects the book shelf image reflecting the operation. Is sent back to the information processing apparatus 10. As a result, a content selection screen similar to that of the present embodiment can be displayed on the information processing apparatus 10.

1 information processing system, 10 information processing device, 20 display device, 21 front touchpad, 70 operation unit, 102 operation reception unit, 104 content acquisition unit, 108 content data storage unit, 110 selection screen control unit, 112 object image generation unit , 114 object image storage unit, 116 arrangement management unit, 118 arrangement information storage unit, 120 selection screen generation unit, 122 content display screen generation unit, 124 display screen control unit.

As described above, the present invention can be used for information processing apparatuses such as computers, portable terminals, information terminals, image processing apparatuses, image display apparatuses, and game machines.
