Therefore, another object of the present embodiment is to realize storage of an arbitrary page and return to the page with an intuitive operation. In addition, the assumptions common to the contents already described in the background art and problems are omitted as appropriate.

[1. Constitution〕
The present embodiment relates to the information processing apparatus 1 (hereinafter also referred to as “this apparatus 1” or “this apparatus”) shown in the configuration diagram of FIG. The apparatus 1 is a mobile terminal such as a smartphone or a tablet PC, or a client apparatus such as another personal computer, and is also referred to as a “terminal”. The server 2 is a device that provides a document file such as an electronic book file in response to a request.

  The apparatus 1 includes at least an arithmetic control unit 6 such as a CPU, a storage device 7 such as a main memory and an auxiliary storage device (for example, a flash memory), and a communication network N (for example, a mobile phone, PHS, And a communication means 8 (for example, a communication circuit with a wireless communication network, a wireless LAN adapter, etc.) with various wireless communication networks such as a public wireless LAN and the Internet. In addition to the computer configuration as described above, the present apparatus 1 has a display screen G which is an input / output means using a liquid crystal with a touch panel function or an organic EL.

  In the present apparatus 1, the arithmetic control unit 6 executes a predetermined computer program such as an electronic book viewer program stored in the storage device 7, thereby realizing the elements (12, 50, etc.) shown in FIG. To do. Of the elements to be realized, the mode of the information storage means is arbitrary, and can be realized in any data format such as a file on the storage device 7, or may be remote storage by network computing (cloud).

  The storage means may include not only a data storage area but also functions such as data input / output and management. In addition, the unit of the storage means shown in this application is for convenience of explanation, and the configuration can be divided or integrated as appropriate, and the processing data and processing results of each means are stored in addition to the explicit storage means. A storage means is used as appropriate.

  Of the storage means, the document file storage means 55 is a means for storing electronic book files and other document files downloaded from the server 2 via the communication network. Further, the specific page storage means 13 is a means for storing a page related to a bookmark operation described later (for example, FIG. 2).

  The arrows in the figure (for example, FIG. 1) supplementarily indicate the main direction of the flow of data, control, etc., and do not deny other flows or imply direction limitations. For example, before or after data acquisition in a certain direction, a data request or an acknowledgment (ACK) can occur in the reverse direction. In addition, each means other than the storage means is a processing means for realizing and executing the information processing functions and operations (for example, FIG. 1) described below, but these are functional units arranged for explanation. It doesn't matter if it matches the actual hardware elements or software modules.

[2. Effect)
Of the apparatus 1 configured as described above, a processing procedure particularly related to the present embodiment is shown in a flowchart of FIG.
[2-1. (Overview of bookmark operation)
First, in the present embodiment, an operation to return to a desired page area stored by pressing with a finger or the like from a state in which another page is opened by a predetermined return operation (temporarily called “bookmark operation”) is performed.

  As an overview, first, the page display means 50 displays a document file on the screen G of the apparatus 1 for each page region R (R1, R2) (step S11). The document file includes a so-called electronic book, but is not limited thereto, and includes any format or content such as a pdf file or a photo book. Further, the document file to be displayed may be read for each portion for displaying the entire file downloaded in advance in the document file storage means 55, or the necessary range for each portion to be displayed is sequentially transmitted from the server 2 via the communication network N. You may download it.

  Then, the operation detection unit 12 detects a touch operation on the page region R displayed on the screen (step S12). For example, in the example of FIG. 4, the contact range X touched by the finger F indicated by a broken line is indicated by a hatched circle. When the contact range X is within the page region R (R1, R2), the contact is detected as the touching operation.

  Here, the principle of detecting the touching operation is arbitrary, but whatever the principle is used, the detecting operation is not limited to perfect contact, for example, proximity to a predetermined distance that changes the capacitance. including. In addition, touching is not limited to a finger, and a stylus pen is optional. Furthermore, in order to distinguish from operations that touch the screen for other purposes such as normal single-page turning operation or flick operation, bookmark operation is limited to operations that touch the same part continuously for a predetermined time (for example, 0.3 seconds). You may make it detect as touch operation for.

  The page area (for example, R1) in which the touch operation is detected is stored as the specific page by the specific page storage unit 13 while the touch operation is continued (step S13). Specifically, the operation touched by the sensor of the touch panel is detected, and information indicating the start, continuation, and termination of the contact is provided together with the coordinate data. Based on this, the operation detection means 12 starts, continues, You can determine the end and the part of the screen that was the subject.

  Note that even if there is a stored specific page, it is the same as an actual book that an operation of turning a page can be performed so that the page is superimposed on the specific page. When the return operation detection unit 14 detects a predetermined return operation (step S14: “YES”), the return unit 16 changes the display target to the specific page stored in the specific page storage unit 13. (Step S15).

[2-2. Example of return operation)
Among the above, the specific content of the return operation to be detected is arbitrary, but for example, an operation of moving the finger holding the specific page in the center direction of the spread can be considered. In this case, the return operation detection means 14 indicates the center line C of the spread display when the contact area X (FIG. 4), which is the position on the screen touched by the touch operation, is displayed in a spread manner on the screen of the document file. The movement in the direction (for example, the direction of arrow A1 in FIG. 4) is detected as a return operation.

  Here, the center direction of the spread display, that is, the direction along the page turning direction (indicated by the arrow A5 in the lower part of FIG. 5), is not the point of the screen center or the like but the axis of the page boundary corresponding to the binding portion of the book, The direction is toward the center line C. For example, as shown in FIG. 4, when touching the left end of the page region R1 displaying two pages at a time in two-page spread, the operation of moving the position to the right (arrow A1 direction in FIG. 4) Is the return operation. Conversely, when the right end of the page region R1 is touched, an operation for moving the position to the left is a return operation.

  As another example of the return operation, an operation of moving a specific page side such as a tablet PC in a direction in which the screen faces is also conceivable. For example, FIG. 6 is a plan view of the device 1, which is a tablet PC, standing upright in the horizontal direction and viewed from above. In this case, the return operation detecting means 14 is the information processing apparatus displaying the document file on the screen or the position touched by the touch operation on the specific page in the screen (for example, the apparatus 1 shown in FIG. 6). An operation for moving the left side toward the direction (for example, the direction of arrow A3 shown in FIG. 7) at least relatively when viewed from the opposite side in the page turning direction is detected as a return operation.

  Here, “at least relatively” means the opposite direction (for example, the direction of the arrow A4 shown in FIG. 6) that moves the side opposite to the specific page side (for example, the right side of the apparatus 1 shown in FIG. 6) away from the operator. ) To move the specific page side relatively to the operator side facing the screen. Of course, the right side and the left side of the apparatus 1 may be simultaneously moved in opposite directions (directions of arrows A3 and A4 in FIG. 7). Further, the moving operation may be an inclination detected by an acceleration sensor provided in the apparatus 1 or a change in inclination.

  The object to be moved may be the information processing apparatus integrated with the screen G such as a tablet PC or a smartphone, or when the tablet-shaped (plate-shaped) screen is configured separately from the main body of the apparatus 1. It is also possible to move only the screen.

[2-3. (Cancel operation)
When a page that is pressed and stored as a specific page is no longer necessary, the specific page can be deleted by performing a predetermined cancel operation such as shifting the finger outward in the spread display. In this case, the cancel means 40 is stored in the specific page storage means 13 by detecting the movement of the position on the screen touched by the touch operation to the outside of the screen (step S16: “YES”). The specific page is deleted from the specific page storage means 13 (step S17).

  Here, the outside in the spread display is the direction opposite to the direction of the center line C in the spread display in the example of FIG. 4 and is the direction of the arrow A2, but the finger position is closer to the upper end of the specific page. In some cases, a case where the user moves outside the upper page or a case where the finger moves near the lower end of the specific page may include a case where the user moves outside the lower page. Further, the specific content of the cancel operation is arbitrary, and in addition to shifting the pressed finger outward, the operation of simply lifting the pressed finger and releasing it from the screen surface may be the cancel operation (step S16).

[2-3. (Page turning limit)
In addition, while the touch operation continues, it is desirable not to accept the page turning operation beyond the specific page. That is, the page display means 50 is a page turning operation (referred to as “single page turning operation”) that sequentially moves between page areas of the document file while the touch operation is continued (step S18: “YES”), page turning operation to the page area (referred to as “restricted range”) closer to the end of the page than the specific page as viewed from the currently displayed page area is not accepted (step S19: “YES”). ).

  Here, the “winding end side” refers to the beginning side (that is, the first page to the 14th page) from the specific page if the specific page (for example, page 15) is the start side as viewed from the currently displayed page area (for example, page 30). Page), if the specific page (for example, page 50) is at the end of the page (referred to as page 80) when viewed from the currently displayed page area (for example, page 30), the end of the specified page (ie, pages 50 through 80). Page).

  In this case, for example, in a left-opened document file (page flow is from left to right), when the left page is touched (for example, page 15), the page on the intro side (ie, the first page) beyond the touched page. The page cannot be turned in the direction returning from page 14 to page 14). On the contrary, when the right page (for example, page 50) is touched, the page cannot be turned in the direction of going beyond the touched page to the page at the end of the page (that is, page 50 to page 80).

  However, in the case of spread display, as a result of accepting a single page turning operation up to a specific page, it is possible to display an adjacent page that is spread simultaneously with the specific page.

  For a single page turning operation that does not reach the limit range (step S19: "YES"), a display target is displayed together with a predetermined single page turning display, such as accompanied by a page turning animation display, depending on the operation direction (forward / back). The page area is changed (step S20).

  Similarly, for the continuous turning operation described later (step S23: “YES”), when the continuous turning operation is within the restricted range (step S23: “YES”), the turning operation detection means 52 accepts the operation. If it is outside the limit range (step S24: “NO”), the turning display means 54 performs the continuous turning display that turns the page continuously (step S25).

[2-4. (Handling multiple specific pages)
A plurality of specific pages may be stored so that a plurality of fingers are sandwiched between different pages of the book and returned to each. As the simplest example, for example, a specific page is stored in correspondence with each finger, and the specific page corresponding to the finger that has performed the return operation is opened. Specifically, the specific page storage unit 13 stores the finger position information and the specific page in association with each other.

  As an example, in a left-open document file whose right side is the binding side, contact with the first page and left thumb (corresponding to “# 1” in FIG. 2) corresponding to the left index finger (referred to as “# 1” in FIG. 2). In the state where the 15th page is stored as a specific page in correspondence with each other, for example, the index finger is moved to the first page by moving the index finger in the direction of arrow A1 in FIG. Move to page 15 if you move in the same direction.

  Further, apart from the order of touching operations, the order of return can be close to the currently opened page. In this case, the operation detection unit 12 receives a plurality of touch operations for each of the plurality of page areas and stores them in the specific page storage unit 13 as specific pages in the order of the page areas, and the return unit 16 includes the specific page storage unit. 13, the display target is changed to a page area closer to the currently displayed page area among the specific pages stored in 13.

  For example, when a page is displayed on a screen instead of a page spread, the first page, the 15th page, and the 50th page shown in FIG. 2 are stored as specific pages by touching the thumb, index finger, and middle finger. In addition, consider the state in which page 60 is displayed. In this state, every time a predetermined return operation is performed, such as moving the left side of the apparatus 1 forward (for example, FIG. 7), first, the 50th page, then the 15th page in order from the currently displayed page 60. The page opens, and finally the first page opens.

  In the case of spread display, the following operation can be considered. That is, when the document file is spread and displayed among the specific pages stored in the specific page storage unit 13, the return unit 16, when viewed from the currently displayed page area, The display target is changed to a page area that is closer to the page area that is currently displayed.

  For example, the page area on the right side of the currently displayed page area is the 40th page, and among the three specific pages shown in FIG. 2, the first page and the 15th page are the left side of the spread, as shown in FIG. The left edge of the screen belonging to the page area is stored by touching with the two fingers F1 and F2 of the left hand, and the 50th page is stored by touching the right edge of the screen belonging to the page area on the right side of the spread with the right finger F3. Think about the state you are letting.

  In this state, when a return operation is performed to move the left side of the tablet PC to the front (FIG. 7), the 50th page, which is the right side on the opposite side as viewed from the current 40th page, is closest to the 10th page. Without moving to the 50th page, the page 15 is moved to the nearest page 15 on the side related to the return operation, and if the return operation is performed again on the same left side, the process moves to the first page. If a return operation is performed to move the right side of the screen to the front, the process moves to page 50.

[2-5. (Effects related to bookmark operation)
(1) As described above, in this embodiment, when a document file page (for example, R1 in FIG. 4) displayed as an electronic book or the like is touched with a finger F or the like (for example, step S12 in FIG. 3). ("YES") The page is stored (for example, FIG. 2, Step S13), and after receiving a predetermined return operation (for example, FIG. 7) (Step S14: "YES"), returning to that page (Step S15) Since the operation is based on an actual book, storage of an arbitrary page and return to the page can be realized by an intuitive operation.

(2) In particular, in the present embodiment, an operation for shifting the position of the finger touching the page in the center direction (for example, the direction of arrow A1 in FIG. 4) when the page is displayed is detected as a return operation and the screen returns to the touched page. As a result, the operation is based on the operation of moving the finger sandwiched between pages in the actual book to the binding side of the spread page and returning to the sandwiched page, so that it is possible to return to the stored page with a more intuitive operation. it can.

(3) Further, in this embodiment, as shown in FIG. 7, for the terminal such as a tablet PC displaying a document file, the side touched with a finger is compared with the actual side or the other side. By moving back to the touched page by detecting an operation to move to the near side (for example, in the direction of arrow A3 in FIG. 7) as a return operation, the side with the finger in the actual book is moved to the near side. Since the operation is similar to the operation of returning to the page sandwiched by removing the page to the opposite side, it is possible to return to the stored page by a more intuitive operation.

(4) Further, in the present embodiment, an operation of moving the position of the finger touching the page to the outside of the screen, that is, the terminal (for example, in the direction of arrow A2 in FIG. 4) is detected (for example, step S16 in FIG. 3: “YES” )) By deleting the information about the stored specific page and canceling it (step S17), the operation according to the operation of removing the finger sandwiched from the page that is no longer necessary in the actual book and stopping returning. Therefore, more intuitive operation can be realized.

(5) In addition, in this embodiment, by not accepting a page turning operation to a page beyond the page touched with a finger as viewed from the currently displayed page (for example, step S19: “YES” and step S24: “YES”), the operation conforms to the actual situation in which the page is not turned beyond the page where the finger is sandwiched in the actual book, so that more intuitive usability can be realized.

(6) In particular, in the present embodiment, a touch operation with a different finger is received for each of a plurality of pages and stored as a specific page (for example, FIG. 2). By returning, it is possible to realize usability that is not inferior to the actual situation in which a plurality of fingers may be sandwiched between different pages in an actual book.

(7) In this embodiment, even when a plurality of specific pages are stored for each side in the spread display, the specific page on the return operation side is returned to the specific page in the order closer to the current page. By doing so, more complicated operations can be easily realized with a simple user interface.

[2-6. (Overview of turning operation)
Second, the present embodiment performs an operation of turning the flip and the page region continuously (referred to as a “turning operation”) by shifting a finger or the like at a so-called fore edge portion of the page edge.

  As an outline of the operation, first, as illustrated in FIG. 6, when an end portion of the page area R (R1, R2) of the document file is touched (in the direction of arrow A5 in FIG. 6) (step S21: “YES”), the page display means 50 displays the fore edge K at its end (step S22 in FIG. 3).

  Then, the turning operation detection unit 52 touches the portion of the screen on which the forehead K is displayed with the finger F or the like, and determines the position of the contact on the outer side in the page turning direction as viewed from the end page area (arrow A6 in FIG. 6). When the operation moving in the direction is detected as a turning operation (also referred to as “continuous turning operation”) (step S23: “YES”), the page area is determined according to the speed and amount of movement in the continuous turning operation. Is continuously displayed by an animation display imitating the state of turning pages in a paper book.

  The contact position in the continuous turning operation is the start point of the contact range X touched by the finger F or the like (indicated by a halftone dot circle in FIG. 6 as in FIG. 4) (for example, the upper left of the circumscribed rectangle of the contact range) (Corner) and the coordinates of the center of gravity, etc.

  When a continuous turning operation is detected (step S23: “YES”), the turning display means 54 accepts the detected continuous turning operation except for the above-mentioned limit range (step S24: “NO”), and the continuous turning operation is performed. Depending on the amount of movement, etc., the page area is continuously turned (step S25).

  The continuous turning operation is not limited to the operation of moving the position to the outside while touching the portion of the screen corresponding to the fore edge K as described above, and may be another predetermined turning operation. Examples of other turning operations include an operation of tilting the terminal, and a finger touching the fore edge is moved inward (in the direction of the center line C). As a result, a display in which the page area is continuously turned is performed according to the magnitude of the tilt angle of the terminal and the speed and amount of finger movement.

[2-7. (Turning time interval control)
The display time interval for continuously turning the page area according to the continuous turning operation is controlled according to the amount of movement, the width of the forehead, the movement of the device, and the like (step S25). That is, first, the turning display means 54 performs a display of continuously turning the page area with a quantity corresponding to the amount of movement. For example, if the movement amount is reduced by slightly increasing the width and speed of finger movement. The display turns relatively slowly, and if the movement width and speed are increased to increase the movement amount, the display turns quickly one after another.

  Further, the page display means 50 displays the edge K (K1, K2, K3...) Corresponding to the page area closer to the displayed page area wider than the edge corresponding to the farther page area (for example, FIG. 6). , K1> K2> K3..., And the turning display means 54 performs a display of turning the page area continuously at a time interval corresponding to the width of the fore edge K related to the detected continuous turning operation (step S25).

  The above example (FIG. 6) exemplifies the continuous turning operation for the edge K at the right end of the screen, but the continuous turning operation is also possible on the left side of the screen as well. Is left-right symmetric.

  Further, the page turning display means 54 opposes the fore edge related to the detected continuous page turning operation in the apparatus 1 (information processing apparatus) displaying the document file on the screen or the screen G in the page turning direction. Detects an operation to move in the direction that the screen is facing from the side, and displays the page area continuously at time intervals according to the amount of movement (rotation angle, angular acceleration, etc.) (steps) S25).

  For example, as shown in FIG. 7, the same side of the apparatus 1 can be moved in the direction in which the screen G is facing (the direction of arrow A3 in FIG. 7) while continuously turning the edge of the left end of the screen. For example, the larger the angle of movement and the faster the movement, the shorter the time interval of continuous turning display, the continuous turning display is accelerated, and a display in which many pages are turned in a short time.

  Also in this case, the opposite side, for example, the right side is moved in the direction of arrow A4 in FIG. 7 and the left side is moved relatively to the side facing the screen G, or the right and left sides of the apparatus 1 are opposite to each other ( It may be moved simultaneously in the directions of arrows A3 and A4), and the object to be moved may be only a screen configured separately from the main body.

[2-8. Other control examples)
Further, the fore edge K may be displayed on the screen together with the page area of the document file from the beginning, for example, from the time of step S11. In this embodiment, the edge K is displayed when the edge is touched. That is, in this embodiment, the page display means 50 is touched at the end in the page turning direction of the portion of the screen (for example, the screen G in FIG. 4) where the page area is displayed (step S21: “ YES ”), the fore edge K is displayed at the end (FIG. 6, step S22).

  Specifically, the fore edge K is not always displayed clearly, but is normally hidden or semi-transparent display, etc. When touching that part, the display density of the fore edge K itself is increased or the upper side of the fore edge K is displayed. Fore edge K is displayed by increasing the transparency of the semi-transparent layer located.

  Further, the turning operation detecting means 52 detects the position touched at the start of the continuous turning operation in the thickness direction of the fore edge K, and the page display means 50 displays the page area corresponding to the detected position, and turns. The display means 54 can also perform a flip display from the page area displayed according to the detected position. Also in this case, the reference of the touched position is arbitrary, and for example, the barycentric coordinates of the touched area can be considered. The type of continuous turning operation is also arbitrary, and the operation of touching the fore edge at the start may or may not be included in the continuous turning operation.

  For example, when the device 1 is tilted by touching a predetermined position of the fore edge K, page turning starts after moving to the corresponding page. Alternatively, when it is detected that the finger has been moved inward (for example, in the direction of arrow A7 in FIG. 6) after touching a predetermined position of the fore edge K, page turning starts after moving to the corresponding page.

  As a page according to the position, for example, when the 50th page is displayed from the left to the right from the first page to the 100th page, the left edge (corresponding to the first page → the 50th page) is displayed. The right fore edge (corresponding to page 51 → page 100) is approximately equal in width to each other. For example, the right fore edge (corresponding to page 51 → page 100) on the end side of the right side If the continuous turning operation is started by touching, the display of turning from the vicinity of the 75th page is started.

  As another aspect, by counting the number of times displayed for each page area and the time, the page turning frequency is reduced (that is, the time interval is increased) or the chapters marked in the document file data are counted. The turning speed may be reduced near the beginning of. In addition, characters such as the text of the document on the page area when the forehead is displayed may be displayed with the inclination reflected (for example, FIG. 8) assuming that the viewpoint is moved to a position where the forehead is visible. However, it may be displayed flat as shown in FIG. 6 without considering such inclination.

[2-9. Effect on turning operation)
(1) As described above, in the present embodiment, the finger is moved (for example, in the direction of arrow A6 in FIG. 6) while touching the right edge or left edge of the edge K of the document file displayed on the screen as an electronic book or the like. By flipping the pages continuously, the operation conforms to the actual book, so the pages of the electronic book can be turned by an intuitive operation.

(2) In particular, in the present embodiment, by performing a flip-and-page display with a quantity according to the amount of movement of the finger, that is, the distance and the speed (for example, step S25 in FIG. 3), Since the operation conforms to the operation adjusted by the movement of the finger, the page of the electronic book can be turned by a more intuitive operation.

(3) Further, in the present embodiment, the fore edge closer to the open page is displayed wider and the far edge is gradually narrowed (for example, FIG. 6), and is displayed at time intervals according to the width of the fore edge related to the turning operation. By performing the turning display (for example, step S25 in FIG. 3), even if the finger is moved at the same speed, the first few pages are turned slowly, and the turning speed becomes faster as the next page is turned. The pace can be increased and excellent usability can be realized.

(4) Further, in the present embodiment, the fore edge located at the end of the display page is not always clearly displayed, but is normally hidden or semi-transparently displayed and touched (step S21). : “YES”), by displaying the forehead by increasing the display density of the forehead itself or by increasing the transparency of the semi-transparent layer located above the forehead (for example, FIG. 6), except when used for page turning Since the forehead display is not conspicuous, it is possible to display an easy-to-read electronic book.

(5) In addition, in the present embodiment, for a terminal such as a tablet PC displaying an electronic book, the fore edge related to the turning operation is at least relatively moved to the near side when viewed from the other side (for example, FIG. 7 ) In accordance with the operation of accelerating the page turning by lifting the side of the forehead where the finger is shifted in the actual book, for example, by performing a display that turns at time intervals according to the amount to be performed (step S25 in FIG. 3) Since this is an operation, the page can be turned efficiently by a more intuitive operation.

(6) In particular, in this embodiment, by moving to a page corresponding to the touched position in the width direction of the forehead and starting the display after turning, an arbitrary position in the width of the forehead in the actual book First of all, it is opened in accordance with the operation of shifting the finger from there. Therefore, it is possible to realize a display that turns over a necessary part by a more intuitive operation.
