[Configuration of bookmark setting device]
FIG. 1 is a block diagram illustrating an example of a configuration of a bookmark setting device according to the first embodiment. In the example illustrated in FIG. 1, the bookmark setting device 100 includes a display unit 101, an operation unit 102, an electronic book DB 111, a bookmark information DB 112, and a control unit 120.

  The display unit 101 is connected to the control unit 120. The display unit 101 corresponds to a display, for example. The display unit 101 displays, for example, an arbitrary page of an electronic book stored in the electronic book DB 111 on the screen by being controlled by the control unit 120. Further, for example, the display unit 101 displays bookmark information described later on the screen under the control of the control unit 120.

  The operation unit 102 is connected to the control unit 120. The operation unit 102 corresponds to a keyboard, a mouse, a microphone, a touch panel, or the like. The operation unit 102 receives a turning operation for turning a page of the electronic book displayed on the display unit 101 from the user. That is, the operation unit 102 receives an operation for updating the page first or rearward. For example, the operation unit 102 receives a turning operation from a user using a mouse or a keyboard. Further, for example, the operation unit 102 receives a turning operation from the user by receiving an operation equivalent to turning the paper on the touch panel. The details of the user operation accepted by the operation unit 102 will be described together with the description of the control unit 120 as appropriate. Further, for example, the operation unit 102 receives a selection operation for selecting bookmark information (described later) displayed on the display unit 101.

  The electronic book DB 111 is connected to the control unit 120. The electronic book DB 111 stores electronic books used for various processes by the control unit 120. The electronic book DB 111 corresponds to, for example, a semiconductor memory element such as a flash memory, a hard disk, or an optical disk.

  In the electronic book stored in the electronic book DB 111, an image is formed on a page-by-page basis in the same manner as a normal paper-based book. In the following, a case where an image in page units is formed in advance will be described as an example unless otherwise specified, but the present invention is not limited to this. For example, the size and resolution of a screen for displaying an electronic book may be different for each terminal on which the user views the electronic book. Based on this, when an electronic book is displayed, an image in units of pages may be formed based on the size and resolution of the screen of the display unit 101 that displays the electronic book.

  The bookmark information DB 112 is connected to the control unit 120. The bookmark information DB 112 stores electronic books used for various processes by the control unit 120. The bookmark information DB 112 corresponds to, for example, a semiconductor memory device such as a flash memory, a hard disk, an optical disk, or the like. The bookmark information DB 112 is also referred to as “predetermined storage unit”.

  The bookmark information DB 112 stores bookmark information for uniquely identifying a page of an electronic book. For example, the bookmark information DB 112 stores bookmark information including identification information for identifying an electronic book and page information indicating a page of the electronic book. The detailed significance of the information stored in the bookmark information DB 112 will be described together with the description of the control unit 120. Bookmark information stored in the bookmark information DB 112 is stored by the control unit 120 described later and used by the control unit 120.

  FIG. 2 is a diagram illustrating an example of information stored in the bookmark information DB according to the first embodiment. In the example illustrated in FIG. 2, the bookmark information DB 112 stores a record including “No”, “electronic book name”, “interrupt page”, and “registration date”. Here, “No” is information for uniquely identifying a record stored in the bookmark information DB 112. The “electronic book name” is information for uniquely identifying the electronic book. The “electronic book name” is also referred to as “identification information”. “Interrupted page” is page information indicating a page of an electronic book. Here, each record stored in the bookmark information DB 112 becomes each bookmark information. “Registration date” indicates the date when the record was registered. In the example illustrated in FIG. 2, the bookmark information DB 112 includes NO “1”, the electronic book name “Novel A”, the interruption page “8”, and the registration date and time “2011/02/11/13: 15”. Remember the record.

  The control unit 120 is connected to the display unit 101, the operation unit 102, the electronic book DB 111, and the bookmark information DB 112. The control unit 120 has an internal memory that stores a program that defines various processing procedures and the like, and controls various processes. The control unit 120 is, for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a central processing unit (CPU), or a micro processing unit (MPU). In the example illustrated in FIG. 1, the control unit 120 includes a display control unit 121, a reception unit 122, a calculation unit 123, and a setting unit 124.

  As will be described in detail below, the control unit 120 can return to the original page that was read before the skip reading, for example, when the page to be read is skipped at once, or when the page is flipped in a short time Bookmark information is set automatically based on its high nature.

  That is, when reading a part read in the past in a novel or the like, or when referring to related information in a reference book or a magazine, the page is flipped and read. In this case, the user often returns to the original page and resumes browsing the electronic book after skipping reading is completed. Based on this, as will be described in detail below, the control unit 120 detects whether the user is reading and skipping the electronic book. It is possible to improve operability by automatically setting bookmarks on the page.

  Each unit of the control unit 120 will be described in detail. The display control unit 121 controls display of an electronic book stored in the electronic book DB 111. Specifically, the display control unit 121 acquires an electronic book stored in the electronic book DB 111 and displays an arbitrary page of the acquired electronic book on the display unit 101. Further, when a turning operation is performed on the operation unit 102, the display control unit 121 accepts the turning operation from the operation unit 102, and updates the page of the electronic book displayed on the display unit 101 to the next page. For example, the display control unit 121 displays bookmark information stored in the bookmark information DB 112 on the display unit 101.

  Further, when the display control unit 121 acquires the bookmark information stored in the bookmark information DB 112, the interruption included in the acquired bookmark information among the pages of the electronic book identified by the electronic book name included in the acquired bookmark information. A page indicated by the page is displayed on the display unit 101.

  For example, a description will be given using a case where a selection operation for selecting bookmark information of “1” among bookmark information stored in the bookmark information DB 112 is performed on the operation unit 102. In this case, the display control unit 121 acquires bookmark information identified by NO “1” from the bookmark information DB 112. Then, the display control unit 121 acquires the electronic book identified by the electronic book name “Novel A” included in the acquired bookmark information from the electronic book DB 111, and interrupts the page of the acquired electronic book “Novel A”. Eight pages indicated by the page “8” are displayed on the display unit 101. The display control unit 121 will be described again after the setting unit 124 is described.

  The accepting unit 122 accepts a turning operation from the operation unit 102 when the user performs a turning operation on the operation unit 102. In addition, when the user performs a selection operation on the operation unit 102, the reception unit 122 receives the selection operation from the operation unit 102.

  The calculating unit 123 calculates the amount of change per unit time of the number of pages that have been received by the receiving unit 122 and turned by the turning operation. FIG. 3 is a diagram illustrating an example of the page turning amount per time in the first embodiment. In FIG. 3, the horizontal axis represents the time axis, and the vertical axis represents the page turning amount per time.

  The calculation unit 123 calculates a change amount of the graph indicating the page turning amount per time at a predetermined interval. In the example illustrated in FIG. 3, a case where the amount of change from “t1” to “t2” is calculated will be described as an example. In this case, the calculation unit 123 calculates the amount of change per unit time from “t1” to “t2” by calculating a value with (t2−t1) as the denominator and (p2−p1) as the numerator. . That is, the calculation unit 123 calculates a change amount per unit time by calculating a value obtained by dividing Δp by Δt.

  The setting unit 124 uniquely specifies the page of the electronic book displayed on the display unit 101 when the amount of change equal to or greater than the threshold when the amount of change equal to or greater than the threshold is calculated by the calculation unit 123. Set the bookmark information for the e-book. Specifically, the setting unit 124 includes bookmark information including an electronic book name for identifying the electronic book displayed on the display unit 101 and the number of interrupted pages indicating the page of the electronic book, as bookmark information DB 112. Bookmark information is set by storing in. At this time, the setting unit 124 sets arbitrary “No”, and sets the time for setting bookmark information as “registration date”.

  The setting unit 124 will be further described with reference to FIG. The page turning amount per unit time in the normal browsing state is smaller than the page turning amount per unit time in the skip reading state. For example, in the example illustrated in FIG. 3, “0” to “t1” on the time axis in FIG. 3 indicate a normal viewing state, and “t2” to “t3” indicate a state of skipping reading. As a result, when the normal browsing state is changed to the skipping reading state, as shown in “t1” to “t2” in FIG. 3, the change amount of the page turning amount per unit time is the normal browsing state. Compared to the value calculated while skipping and reading. Based on this, the setting unit 124 detects that the browsing state by the user has changed when the amount of change in the page turning amount per unit time is equal to or greater than the threshold, and when the change occurs or when the change occurs. Bookmark information including the number of interrupted pages indicating the page displayed on the display unit 101 immediately before the occurrence occurs is stored in the bookmark information DB 112. For example, the setting unit 124 stores bookmark information including the number of interrupted pages indicating the page displayed on the display unit 101 at “t1” in the bookmark information DB 112. Here, “t1” indicates a point in time when a change from the normal browsing state to the skip reading state is started, and “t2” indicates a change from the normal browsing state to the skip reading state. Indicates the time of completion.

  For example, the setting unit 124 holds a “status flag” indicating “normally” which is a flag indicating a normal browsing state or “skip reading” which is a flag indicating a skip reading state. In addition, when the status flag is “normal”, the setting unit 124 detects that the normal viewing state has changed to the skipped reading state when the calculation unit 123 calculates a change amount equal to or greater than the threshold value. , Bookmark information is stored in the bookmark information DB 112.

  Note that the setting unit 124 may use any value as the threshold value. For example, “0.6” indicating a change amount of 3 pages every 5 seconds may be used, or another value may be used. A detailed example of processing by the setting unit 124 will be described with reference to a flowchart, and thus description thereof is omitted here.

  In addition, when the bookmark information is set by the setting unit 124, the display control unit 121 displays the set bookmark information on the display unit 101. After that, when the selection operation for selecting the bookmark information displayed on the display unit 101 is received by the reception unit 122, the display control unit 121 receives the electronic book specified by the bookmark information selected by the selection operation. The page is displayed on the display unit 101. In the example shown in FIG. 3, the bookmark information being displayed is selected at “t3”, and after “t3”, browsing is performed in the normal browsing state from the original page.

  The bookmark setting device 100 may be realized by using an information processing device such as a known personal computer, mobile phone, PHS (Personal Handy phone System) terminal, mobile communication terminal, or PDA (Personal Digital Assistant). . For example, it may be realized by mounting each function of the control unit 120 shown in FIG. 1 on an information processing apparatus such as a PDA.

[Processing by bookmark setting device]
FIG. 4 is a flowchart illustrating an example of a processing flow by the setting unit of the bookmark setting device according to the first embodiment. For example, the setting unit 124 periodically repeats a series of processes illustrated in FIG.

  As illustrated in FIG. 4, the setting unit 124 determines whether the status flag is “normal” and the amount of change is equal to or greater than a threshold (step S <b> 101). That is, the setting unit 124 determines whether the browsing state by the user has changed from the normal browsing state to the reading state.

  Here, when the state flag is “normal” and the change amount is determined to be greater than or equal to the threshold value (Yes in step S101), the setting unit 124 displays the change amount when the change amount exceeds the threshold value. Bookmark information for uniquely identifying the page of the electronic book displayed at 101 is set (step S102). For example, the setting unit 124 stores bookmark information including the number of interrupted pages indicating the page displayed immediately before the status flag is changed in the bookmark information DB 112. Then, the setting unit 124 updates the status flag from “normal” to “flying” (step S103).

  On the other hand, in step S101 described above, the setting unit 124 determines that the status flag is “normal” and the amount of change is not less than the threshold (No in step S101). It is determined whether it is “being skipped” and not more than a threshold value (step S104). That is, the setting unit 124 determines whether the status flag should be returned from “flighting” to “normal”. Here, when the setting unit 124 determines that the state flag is “being skipped” and is equal to or less than the threshold value (Yes at Step S104), the setting unit 124 updates the state flag to “Normal” (Step S105). The processing after step S101 is repeated. On the other hand, when the state flag is “being skipped” and is not determined to be equal to or less than the threshold value (No at Step S104), the setting unit 124 ends the process as it is.

  In addition, said process procedure is not limited to said order, You may change suitably in the range which does not contradict a process content. For example, if it is not determined in step S104 that the status flag is “being skipped” and not more than the threshold value (No in step S104), the process is not terminated as it is, but the process returns to step S101. You may return and repeat the process.

[Effect of Example 1]
As described above, according to the first embodiment, the turning operation for turning the page of the electronic book displayed on the display unit 101 is accepted. Then, the amount of change per unit time of the number of pages turned by the accepted turning operation is calculated, and when the amount of change equal to or greater than the threshold is calculated, when the amount of change exceeds the threshold, the display unit 101 Bookmark information for uniquely specifying the page of the electronic book displayed in the electronic book is set in the electronic book. As a result, operability can be improved.

  For example, it is possible to automatically set a bookmark for an electronic book based on the browsing behavior of the electronic book, reduce time and effort required for page transition of the electronic book, and improve the operability of browsing the electronic book. A more detailed example will be described. For example, after skipping several pages, the user often returns to the original page that was being read before skipping and rereads. In this case, according to the bookmark setting device 100, as a result of automatically generating a bookmark for returning immediately before skipping, the user can easily return to immediately before skipping and resume browsing, thereby improving operability. Can be improved. For example, when the skip reading is completed, the user can easily resume browsing from the original page before skip reading by selecting the bookmark generated immediately before the skip reading.

  Further, according to the first embodiment, the setting unit 124 uses bookmark information including identification information for identifying the electronic book displayed on the display unit 101 and page information indicating the page of the electronic book as bookmark information. By storing in the DB 112, bookmark information is set. Further, when the bookmark setting device 100 acquires the bookmark information stored in the bookmark information DB 112, the page indicated by the page information included in the bookmark information among the pages of the electronic book identified by the identification information included in the bookmark information. Is displayed on the display unit 101. As a result, bookmark information can be set for an arbitrary electronic book among a plurality of electronic books, and operability can be improved.

  According to the first embodiment, when bookmark information is set by the setting unit 124, the display control unit 121 displays the set bookmark information on the display unit 101. In addition, when the reception unit 122 receives a selection operation for selecting bookmark information displayed on the display unit 101, the display control unit 121 displays an electronic book specified by the bookmark information selected by the selection operation. The page is displayed on the display unit 101. As a result, the user can immediately return to the original page when the skip reading is completed, and the operability can be improved.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in other embodiments besides the above-described embodiments. Therefore, other embodiments will be described below.

[Display bookmarks]
For example, when the bookmark information is stored in the bookmark information DB 112 for the electronic book displayed on the display unit 101, that is, when the display control unit 121 detects that the normal reading state is changed to the skipping reading state. A bookmark for returning to the page immediately before the change may be displayed on the screen. Here, when the bookmark displayed on the screen is selected, the display control unit 121 displays the original page before skip reading indicated by the bookmark on the display unit. As a result, the user can return to the original page by selecting the bookmark displayed on the screen as soon as the skip reading is completed, and the operability can be improved.

  Further, for example, the bookmark information may not be stored in the bookmark information DB 112 but registered in the electronic book itself. In other words, bookmark information may be included in a part of data forming an electronic book.

[Threshold]
For example, in the example shown in FIG. 4, the same threshold value may be used in step S101 and step S104, or different threshold values may be used.

[System configuration]
Also, among the processes described in this embodiment, all or part of the processes described as being performed automatically can be performed manually, or the processes described as being performed manually can be performed.

In other words, the update program according to the disclosed technology is stored in, for example, the hard disk drive 3080 as the program module 3083 in which instructions executed by the computer are described. Specifically, a program module in which a procedure for executing the same information processing as each unit of the control unit 120 described in the above embodiment is described is stored in the hard disk drive 3080.

  Further, like the data stored in the electronic book DB 111 and bookmark information DB 112 described in the above embodiment, data used for information processing by the bookmark setting program is stored as program data 3084 in, for example, the hard disk drive 3080. The CPU 3020 reads the program module 3083 and program data 3084 stored in the hard disk drive 3080 to the RAM 3012 as necessary, and executes various procedures.

  Note that the program module 3083 and the program data 3084 related to the bookmark setting program are not limited to being stored in the hard disk drive 3080. For example, the program module 3083 and the program data 3084 may be stored in a removable storage medium. In this case, the CPU 3020 reads data via a removable storage medium such as a disk drive. Similarly, the program module 3083 and program data 3084 related to the bookmark setting program may be stored in another computer connected via a network (LAN (Local Area Network), WAN (Wide Area Network), etc.). good. In this case, the CPU 3020 reads various data by accessing another computer via the network interface.
