Abstract

PROBLEM TO BE SOLVED: To refrain from repeating referencing when displaying in a magnified form by referring to oneself. SOLUTION: The section between <;Float...>; and <;/Float>; represents data corresponding to a display area. In the refid attribute, which is an attribute showing reference data, in (e) of the figure, refid = 'myself' indicating reference to oneself, not an ID designating a data to be referred to, is described. When a user moves a cursor of the mouse to the display area corresponding to this data, decision is made as to whether the position of the mouse cursor is within the area of the popup window. If the position is determined to be not within the area of the popup window, a popup window in which oneself is enlarged appears. If the position is determined to be within the area, reference processing is not executed, so reference is not repeated even when the position of the mouse cursor is within the display area at the moment the popup window is displayed.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an information processing apparatus and an information processing method, a recording medium, and a program,
In particular, the present invention relates to an information processing device and an information processing method suitable for browsing an electronic book, a recording medium, and a program.

[0002]

2. Description of the Related Art Conventionally, publication has been performed in books, newspapers, magazines, etc.
Paper has been the main medium. However, with the development of computers and the expansion of their use, and the development of networks, the publication in media other than paper,
That is, electronic publishing has become widespread.

An electronic publication (electronic book) is a digital publication of a book that has been printed and published on paper, and may include not only text and images but also voice and moving images. It is possible. A user downloads an electronic book from a predetermined web server via the Internet and stores the electronic book in a predetermined storage medium, a personal computer, or a predetermined reproducing device, or the electronic book is recorded in advance, for example, a CD. -You can browse electronic books by purchasing recording media such as ROM. The user can reproduce the electronic book by using a personal computer or a predetermined reproducing device in which the data of the electronic book is recorded in the main body or a recording medium in which the data of the electronic book is recorded is mounted. it can.

In these electronic books, a link is provided to a predetermined word or the like, and when the user selects the link, the display screen is jumped to a related portion of the same file, or other related There is a technology in which a book file is opened and displayed on the display screen.

[0005]

For example, an electronic book in which the layout of pages is emphasized (that is, the electronic book has a layout similar to a book published in a paper medium) is given as follows.
When browsing with a device with a small display screen such as a PDA (Personal Digital (Data) Assistants) or an electronic book player, or even if the display screen with a somewhat large device such as a personal computer does not overlap with other display windows In addition, when browsing using a small display viewer, for example, as shown in FIG. 1, if the page is displayed so that the entire page is displayed so that the page layout can be understood, characters and images are displayed small. , It becomes difficult to read as it is.

In order to make the characters and images displayed on the display screen shown in FIG. 1 easier to see, the display screen 2 shown in FIG. 2 may be enlarged and displayed in a fixed size. . However, on the display screen 2, since the entire layout of the corresponding page is completely unknown, it is necessary to operate the scroll bars 3-1 and 3-2 to search for a portion where the content to be read is described.

In order to avoid such a situation, it is necessary to display only a predetermined area in an enlarged manner so that the user can enlarge and display the characters and images required by the user while displaying the layout clearly. There is.

Generally, in structured data, a method of designating an ID of a reference destination is used to execute a reference process. For example, as shown in FIG. 3A, on the display screen 1, an operation of moving the mouse cursor 5 to the display area 4 which is a portion to be enlarged (or double-clicking after moving) is performed. By doing so, in order to display the enlarged display window of the target portion, the data of the portion corresponding to the display area 4 is described as shown in FIG. 3 (B).

In FIG. 3B, <Float ...> And <
The portion surrounded by / Float> is the data corresponding to the display area 4. In the figure (a), id as your own ID
= “1” is described, which is an attribute indicating the data to be referred to
To refer to yourself in the refid attribute, refid = ”
1 "is described. Then, in the figure (b), action =" cursor "is described as an action attribute which is an attribute indicating the operation content for executing the reference process. In c), show = "window" is described as a show attribute that is an attribute indicating the display method, and in (d) in the figure, as poswindow attribute indicating the display position of the window, poswind
ow = “Lower” is described.

At this time, as shown in FIG.
When the enlarged display window 6 is displayed, the mouse cursor 5 is included in the display area at the moment when the enlarged display window 6 is displayed, so that the reference process is further performed. As described above, if the user refers to himself / herself by using the ID, the process may enter a loop and may not end.

To avoid this, if the reference processing is not performed in the enlarged display window 6, a link is set in the enlarged display window 6, different content, or different pages of the same content are displayed. When it is designed to refer to, the process cannot be performed.

[0012] For example, "fresh eggs" in the display area 4
The color of the text described as is different from that of the other texts, and the mouse cursor 5 is moved to the text to be clicked, so that the description about "how to identify a fresh egg" described in different content is given. When it is designed to be jumped to, since the characters are difficult to see in the display area 4 before the enlarged display, the user may not be aware that a link is put in the text of “fresh egg”. There is. However, even if the user who has displayed the enlarged display window 6 wants to jump to the link from the text "fresh egg" and moves the mouse cursor 5 to perform a click operation, the jump process is executed. Not done.

In such a case, in order to execute the jump processing to the link destination, the user performs an operation to erase the display of the enlarged display window 6 and then clicks the corresponding text. There must be. Therefore, the electronic book set so that the reference processing cannot be performed in the enlarged display window 6 is very inconvenient for the user and has poor operability.

Further, in order to execute the reference processing in the enlarged display window while avoiding that the processing enters a loop and never ends, as shown in FIG. 4B, the position of the mouse cursor 5 is changed. When the magnified display window 7 is displayed avoiding, only the magnified display window 7 whose size is not so different from the display area 4 can be displayed depending on the position of the mouse cursor 5. The rate becomes very small, and in the end, there is a risk that characters and the like will be difficult to see.

The present invention has been made in view of such a situation, and when a portion desired by the user is enlarged and displayed, other reference processing and link commands described in the data in the area are stopped. Without doing so, it is possible to provide an electronic book that does not repeat the reference processing.

To 124-p, the user selects and reads the desired content file, decodes the tag information, and a new content file input via the file input control unit 117 or a resource file file recording unit 113. Control recording to.

Here, the resource file is a file referred to by the content file, and basically corresponds to the above-mentioned object file, but a tag may be described in the resource file. Needless to say. In addition, a tag for referencing another content file may be described in the content file.

That is, the tag information decoding unit 111 analyzes the tags of the selected and read content files 121-1 to 121-n or 123-1 to 123-P, and if necessary, the resource file 122. -1
To 122-m, or 124-1 to 124-q,
Alternatively, a content file other than the initially selected content file is read, display data of the electronic book is generated, and output to the display control unit 115.

The display control unit 115 receives the display data of the electronic book and controls the display unit 116 to display the input display data of the electronic book.

The file recording section 113 may be downloaded via the Internet 20, or
It records data copied from various recording media, and records content files 121-1 to 121-n and resource files 122-1 to 122-m. The external recording unit 114 corresponds to various recording media such as the magnetic disk 14, the optical disk 15, the magneto-optical disk 16 or the semiconductor memory 17 described above, and all devices capable of recording information. The files 123-1 to 123-p and the resource files 124-1 to 124-q are recorded.

Hereinafter, when it is not necessary to individually distinguish the content files 121-1 to 121-n, they are simply referred to as the content file 121, and the resource file 12
When it is not necessary to individually distinguish 2-1 to 122-m, they are collectively referred to as the resource file 122, and when it is not necessary to individually distinguish the content files 123-1 to 123-p, they are simply referred to as the content file 123. However, when it is not necessary to individually distinguish the resource files 124-1 to 124-q, the resource file 12
Collectively referred to as 4.

Next, the content display process will be described with reference to the flowchart of FIG.

In step S1, the tag information decoding unit 1
11 is based on the signal input from the operation input unit 112,
Whether or not a display command for content (data corresponding to an electronic book) is received, that is, by a predetermined operation,
It is determined whether a command to browse the electronic book has been input.
If it is determined in step S1 that the content display command has not been input, the process of step S1 is repeated until it is determined that the content display command has been input.

When it is determined in step S1 that a content display command has been input, the tag information decoding unit 111 stores the designated content file 121 or 123 in the file recording unit 113 or the outside in step S2. It is read from the recording unit 114.

In step S3, the tag information decoding unit 1
11 analyzes the tag of the content file 121 or 123 read in step S2.

In step S4, the tag information decoding unit 1
11 determines whether or not data reference is instructed by the Float tag.

When it is determined in step S4 that the data reference is instructed, the tag information decoding unit 111 determines in step S5 whether or not the action attribute is found.

When it is determined in step S5 that the action attribute is found, the tag information decoding unit 111 reads and stores the refid attribute and the action attribute from the content file 121 or 123 in step S6.

If it is determined in step S5 that the action attribute has not been found, the data for which reference is instructed is displayed without waiting for an action (it is always inserted and displayed in the content file 121). Therefore, in step S7, the tag information decoding unit 111
Is a file recording unit 113 or an external recording unit 114,
Alternatively, a file instructed from another information processing device such as the personal computer 12 is acquired via the Internet 20, and is processed so as to be displayed in a specified size at a specified location according to a tag and an attribute.

When it is determined in step S4 that the data reference is not instructed, the tag information decoding unit 111 executes the display processable tag in step S8.

After the processing of step S6, step S7, or step S8 is completed, in step S9, the tag information decoding section 111 determines whether or not all the tags of the content file 121 or the content file 123 have been executed. .

When it is determined in step S9 that all the tags of the content file 121 or the content file 123 have not been executed yet, the process returns to step S3, and the subsequent processes are repeated. In step S9, the content file 12
If it is determined that the tag 1 or all the tags of the content file 123 have been executed, the process ends.

By such processing, the tag information decoding unit 1
11 is the content file 12 designated by the user
1, or the content file 123 is read, and the tag of the content file 121 or the content file 123 is analyzed and executed to display the electronic book. At that time, the tag information decoding unit 111, based on the description of the tag information or the attribute information, if necessary, another content file 121, a content file 123, or a resource file 122.
Alternatively, the resource file 124 may be read from a designated location and displayed as a part of an electronic book, or re-processed for processing to be executed when a predetermined action is received.
The fid attribute and action attribute can be read and stored.

Here, when a predetermined action is received,
When the reference destination indicated by the refid attribute is another file (other content file 121 or content file 123, or resource file 122 or resource file 124), the specified file is read from the specified location. The process for displaying is executed, but if the reference destination indicated by the refid attribute is oneself, the self-expanding reference process for enlarging and displaying oneself is executed.

Next, referring to the flowchart of FIG. 11, the process is executed when a designated action is received.
Reference data display processing including self-enlargement reference processing will be described.

In step S21, the tag information analysis unit 111 inputs the specified action in the specified area based on the user operation input through the operation input unit 112 and the position of the mouse cursor 5. Determine whether you have received.

For example, as shown in FIG. 12, the user operates the mouse cursor 5 on the display screen 151 similar to the conventional display screen 1 described with reference to FIG. A case will be described.

Display area 15 of display screen 151 of FIG.
The XML data corresponding to No. 2 is shown in FIG.

In FIG. 13, <Float ...> and </ Float
The portion surrounded by at> is the data corresponding to the display area 152. In order to refer to the refid attribute, which is the attribute indicating the data to be referenced, in (e) of the figure, the refid
= "Myself" is described. Here, since the display area 152 is not referenced by anyone other than itself, the ID used when it is referenced by others is omitted. Then, in (f) of the figure, as an action attribute that is an attribute indicating the operation content for executing the reference process,
= “Cursor” is described. "Cursor" indicates an operation for moving the mouse cursor 5 into the designated area. acti
The on attribute may specify, for example, single click, double click, or pressing of a predetermined button.

Also, in the figure (g), show = "popup" is described as a show attribute which is an attribute indicating the display method.
In (h) of the figure, pospopup = "Lower" is described as the pospopup attribute indicating the display position of the popup window. In addition to the pospopup attribute indicating the position information, for example, an attribute for describing the size of a displayed character or the size of a graphic may be prepared.

That is, the data described with reference to FIG. 13 shows that when the user inputs an operation to move the mouse cursor 5 to the display area 152 of FIG. This is data for displaying the enlarged popup window.

If it is determined in step S21 that the designated action is not input in the designated area, the steps are repeated until it is determined that the designated action is input in the designated area. The process of S21 is repeated. When it is determined in step S21 that the designated action is input in the designated area, the tag information analysis unit 111 determines in step S22 whether or not jump processing to the link destination is instructed. To do.

When it is determined in step S22 that the jump processing to the link destination is not instructed, the tag information analysis unit 111 in FIG.
Refid attribute stored in step S6 of
= Judge whether or not it is "myself".

In step S23, refid = "mysel"
If it is determined to be "f", in step S24, the tag information analysis unit 111 determines whether the input of the action is in the enlarged display window or the pop-up window.

In step S24, if it is determined that the action input is received in the enlarged display window or the pop-up window, refid
Since “= self” refers to itself, the process is terminated without performing any process so that the reference is not repeated.

If it is determined in step S24 that the action input is not in the enlarged display window or the pop-up window, in step S25, the tag information analysis unit 111 describes the show attribute. Read the display method. For example, in FIG.
The display method described in the show attribute in the data shown in is the display of a pop-up window. Here, as the display method described in the show attribute, it is assumed that the display of a popup window or the display of an enlarged display window is prepared.
It goes without saying that other display methods may be described in the ow attribute.

The tag information analysis section 111 determines in step S26.
In, po indicating the display position of the popup window
spopup attribute, posw indicating the display position of the enlarged display window
The stylesheet such as the size of the font and graphic data specified by the indow attribute or other attributes is read and analyzed, and in step S27, the data corresponding to the framework of the popup window or the enlarged display window (that is, the internal Data corresponding to a pop-up window or a magnified display window in which no data is displayed is generated.

The tag information analysis section 111 determines in step S28.
In step S29, the data in the element itself is read, and in step S29, the read data is described in the pop-up window or the enlarged display window.

In step S30, the tag information analysis unit 111 displays the data corresponding to the generated popup window or enlarged display window in the display control unit 11.
Output to 5. The display control unit 115 controls the display unit 116 to display a pop-up window or an enlarged display window, and the process is ended.

A display screen 15 in which a pop-up window 161 corresponding to the display area 152 is displayed in FIG.
1 is shown. On the display screen 151 of FIG. 14, the mouse cursor 5 is included in the area of the displayed popup window 161, but the reference destination is not the ID,
Since it is specified as "myself", which indicates itself,
Reference processing is not executed.

FIG. 15 shows a display screen 151 on which an enlarged display window 171 corresponding to the display area 152 is displayed. On the display screen 151 of FIG. 14, the mouse cursor 5 is displayed in the area of the displayed enlarged display window 171.
Is included, but since the reference destination is specified by "myself" indicating itself rather than the ID, the reference processing is not executed again.

In step S23, refid = "mysel"
When it is judged that it is not f ”, the data to be referred is
Data from other files, not yourself, or
It is data of another part of the same content. In steps S31 to S33, the same processing as steps S25 to S27 is executed.

In step S34, the tag information analysis unit 111 stores the designated reference data (data designated by the ID and data other than itself) in the file recording unit 11.
3, read from another information processing apparatus (for example, the personal computer 12 described using FIG. 5) via the external recording unit 114 or the Internet 20.

In step S35, the tag information analysis unit 111 describes the data read in step S34 in the pop-up window or the enlarged display window generated in step S33.

In step S36, step S30
A process similar to is executed and the process ends.

When it is determined in step S22 that the jump processing to the link destination is instructed, the tag information analysis unit 111 reads the data designated as the link destination in step S37, and reads it in step S38. The linked data is output to the display control unit 115. The display control unit 115 controls the display unit 116 to display the page of the link destination, and the process ends.

By such processing, the reference processing is repeated without stopping the execution of the jump instruction to the link destination or the reference instruction in the popup window or the enlarged display window generated by referring to its own data. You can prevent it from entering a loop because it can be turned off.

On the display screen 151, when it is difficult to know which portion can be enlarged and displayed, for example, as shown in FIG. 16, the mouse cursor 5 is moved to the enlarged and displayable display area. In this case, the display of the mouse cursor 5 may be changed from an arrow to a magnifying glass. When the display of the mouse cursor 5 is changed by the magnifying glass, the user can enlarge and display the corresponding display area 152 by executing a predetermined operation such as double-clicking or left-clicking.

Further, as shown in FIG. 17, a display area 152 and display areas 181 to 181 capable of enlarged display are provided.
An icon 191 indicating that enlarged display is possible on 83
Through 194 may be displayed.

When the icons 191 to 194 are displayed, the self-expansion reference process is performed when the operation indicated by the action is performed in the display area 152 and the display areas 181 to 183 as in the above-described process. The pop-up window 201 as shown in FIG. 18 may be executed to display the self-expansion reference process when the operation indicated by the action is performed on the icons 191 to 194. Then, a pop-up window 201 as shown in FIG. 18 may be displayed.
