Abstract

When displaying a hierarchical presentation document while manually changing pages, it is possible to easily understand how pages are changing in the whole with a relatively simple configuration. In response to a swipe operation on the touch panel (S0), if the next page of the current page does not exist (S1, S3), the connection source page of the current sub-document is displayed on the display device 17 (S6, S8, In S9), if there is no previous page of the current page (S2, S3), the display device 17 displays the connection source page of the current sub-document. When displaying the link source page, the link destination page is superimposed on this page, and this is the slide direction when the page transitions in the direction opposite to the slide direction when the link destination is the transition destination and within the same sub-document. The display area is reduced while sliding in the direction perpendicular to the axis. [Selection] Figure 5

Description

  The present invention relates to a presentation document display apparatus that shifts pages of a hierarchical presentation document in accordance with an instruction input and a program thereof.

  Patent Document 1 below discloses an apparatus that displays a hierarchical presentation document. According to this apparatus, a table of contents can be specified by a program, and the page can be created and displayed. For pages other than the table of contents page, the position of the current page can be grasped by writing a symbol indicating the position in the hierarchical structure on the page.

WO2009 / 087999

  However, this symbol may not be written in the layout space, it may be difficult to see because the symbol size is small, or the symbol may be overlooked because it is a peripheral part of the screen.

  On the other hand, when a hierarchical presentation document is displayed with manual page transitions, part of the hierarchy may be omitted or the pages may be moved back and forth depending on the viewer's level of understanding and time. Display pages in the same hierarchy multiple times. At that time, even if the above symbols are missing or small, if you can easily understand how the page is changing in the whole page, the understanding level of the viewer can be improved or the explainer can change the page. You can avoid being confused. Further, since the document is hierarchized and complicated, it is preferable to avoid further complication of the structure.

  The object of the present invention is to focus on such points, and when displaying a hierarchical presentation document while manually changing pages, how the pages change in the whole with a relatively simple configuration. It is an object of the present invention to provide a presentation document display device and a program thereof that make it possible to easily grasp whether or not a user is present.

In a first aspect of the presentation document display device according to the present invention, a processor, a storage device storing a page transition program and a presentation document, an instruction input means, and a display device are provided, and the presentation document is one page or serial. The sub-documents other than the root are linked to at least one page (link source page) to one page (link destination page) of the other sub-document, and the page transition program is For the processor:
(A) In response to a connection destination page display instruction input from the instruction input means, display a connection destination page of a sub-document connected to the current page on the display device;
(B) In response to the next page display instruction input from the instruction input means, if there is a next page of the current page, the next page is displayed on the display device. The connection source page corresponding to the connection destination page in step (a) is displayed on the display device.

The “one-page or multi-page sub-documents connected in series” indicates that a program included in one page or a program included in at least one page among the plurality of pages connected in series is a button to the processor. A configuration may be included in which a static page is dynamically generated in response to an instruction input such as pressing.

In a second aspect of the presentation document display device according to the present invention, in the first aspect, the page transition program sends the processor to the processor.
In step (a), transition to the connection destination page is performed by increasing the display area of the connection destination page while superimposing the connection destination page on the current page and sliding the connection destination page in one direction. Let
When displaying the connection source page in step (b), the display area of the current page is increased while the current page is superimposed on the connection source page and the current page is slid in the direction opposite to the one direction. By reducing, transition to the link source page,
When displaying the next page or the previous page in step (b), the display area of the next page or the previous page is increased while sliding the next page or the previous page in a direction perpendicular to the one direction. Or by instantaneously switching to the next page or the previous page.

In a third aspect of the presentation document display device according to the present invention, in the first or second aspect, the page transition program is provided to the processor.
In step (a), the address of the connecting original page is pushed onto the stack area of the memory device, in step (b), shifts by popped from the stack area to the page of the content.

  According to the configuration of the first aspect, in response to the next page display instruction input from the instruction input means, if the next page of the current page does not exist, it corresponds to the connection destination page of the step (a) closest in time. Since the connection source page is displayed on the display device, the presenter and the viewer can easily grasp the transition from the connection destination page of the sub document to the connection source page of the other sub document displayed previously. In addition, there is an effect that it is not necessary to put a link to the connection source page on the connection destination page, and it is not necessary to arrange the button.

  According to the configuration of the second aspect, when the connection destination page is displayed, the current page of the connection destination page is superimposed on the connection source page, and the current page is the transition destination page. Since the display area of the current page is reduced while being slid in the direction opposite to the slide direction and the direction perpendicular to the slide direction at the time of page transition in the same sub-document, the transition is made to the connection source page. There is an effect that the presenter and the viewer can more easily grasp the transition from the connection destination page of the sub-document to the connection source page of another sub-document.

According to the configuration of the third aspect, regardless of the complexity of the hierarchical structure, the address of the connection source page is pushed to the stack area when transitioning to the connection page, and conversely when the transition to the connection source page is performed. In a simple configuration of popping from the stack area and transitioning to the page of the contents, the user does not need to perform an operation of placing a button embedded with a link to the connection source page on the connection destination page, The page structure is simplified, and the document structure can be prevented from becoming complicated.

It is a schematic block diagram which shows the hierarchical structure of the presentation document based on Example 2 of this invention.

  FIG. 1 is a schematic block diagram illustrating a hardware configuration of the information processing apparatus 10 according to the first embodiment of the present invention.

  The information processing apparatus 10 is, for example, a tablet computer, a notebook computer, or a desktop computer. In the information processing apparatus 10, a processor 11 is coupled to a solid state drive 13, a DRAM 14, a communication adapter 15, an input device 16, and a display device 17 through an interface 12. In FIG. 1, a plurality of types of interfaces are represented by one block 12 for simplification.

  The solid state drive 13 is an auxiliary storage device such as a flash memory having a large storage capacity, and stores programs and data. This data includes a presentation document, and this program includes a virtual storage operating system and applications. The application includes a page transition program that transitions the page of the document according to an instruction input from the input device 16.

  The DRAM 14 is used as a main storage device and a video RAM (which may be included in the main storage area) in the virtual storage system. The communication adapter 15 is coupled to a network such as a LAN or the Internet via an antenna 18 and radio waves. For example, a presentation document created by a desktop computer (not shown) is stored in the solid state drive 13 via the communication adapter 15. The input device 16 is, for example, a touch panel, a keyboard, and a pointing device. Below, the case where the input device 16 is a touch panel is demonstrated.

  The presentation document is hierarchized, and includes a plurality of sub-documents of one page or a plurality of pages connected in series. Sub-documents other than the root are those whose first page (link destination page) is one of other sub-documents. It is linked to the page (link source page).

Each page of the presentation document is composed of a container and content arranged in the container, and the content includes one or more objects such as text, graphics, and images. The content may include a spreadsheet application sheet, CAD data, or Web content. In the case of Web content, the content may include a script for configuring a dynamic page such as an animation.

  In the following, the j-th subpage (j is an integer greater than or equal to 0) of the i-th subdocument (i is an integer greater than or equal to 0) of the presentation document is referred to as the (i, j) page of the presentation document. The page identifier (i, j) is logical and may actually be only the page address of the hyperlink, for example.

  FIG. 2A is a schematic block diagram showing a partial hierarchical structure of the presentation document, and shows the relationship between the i-th sub-document SUBi and the (i + 1) -th sub-document SUB (i + 1).

  The subdocument SUBi is composed of (i, 0) to (i, 3) pages, and the subdocument SUB (i + 1) is composed of (i + 1,0) to (i + 1,2) pages. In each sub-document, adjacent pages (between sibling nodes) are mutually linked (first link), and in the figure, this link (connection) is indicated by a solid line with a double-pointed arrow.

  The sub-documents are linked (second link) from the (i, 1) page of the sub-document SUBi to the (i + 1, 0) page of the sub-document SUB (i + 1). That is, the page (i + 1, 0) of the sub-document SUB (i + 1) is the page to be linked to the page (i, 1) of the sub-document SUBi. This link (second link) is different from the link between the sibling nodes (first link) in that a link button in which the link is embedded is added to the connection source page.

  A dotted line with an arrow indicates a return link (third link) from the first page or the last page of the subdocument to the connection source page. This link is regularly performed by the page transition program as described later. There is no need to place a link button on the first page or the last page of the sub-document.

  FIG. 2B is a schematic block diagram showing a more specific hierarchical structure of the presentation document.

  This document is composed of sub-documents SUB0 to SUB4. The first to third links are the same as described above.

  The sub-document SUB0 is the title or / and table of contents page of the presentation document, and consists only of (0, 0) pages.

  The sub-document SUB1 is a basic part of the presentation document and includes pages (1, 0) to (1, 4). From the (0, 0) page of the sub-document SUB0 to the (2, 0) page of the sub-document SUB1. Linked.

  The sub-document SUB2 describes the (1,1) page of the sub-document SUB1 in more detail, and includes (2,0) to (2,3) pages. The sub-document SUB2 includes (1,1) of the sub-document SUB1. The page is linked to the (2,0) page of the sub-document SUB2.

  The sub-document SUB3 describes the (2,0) page of the sub-document SUB2 in more detail, and includes (3,0) to (3,1) pages. The sub-document SUB3 includes (2,0) of the sub-document SUB2. The page is linked to page (3, 0) of sub-document SUB3.

  The sub-document SUB4 describes the (1,3) page of the sub-document SUB1 in more detail, and is composed of pages (4,0) to (4,1), and the (1,3) of the sub-document SUB1. The page is linked to page (4,0) of sub-document SUB4.

  FIG. 3 shows a user interface screen 20 displayed when the presentation document creation program is started. This program is installed in a notebook computer (not shown) or a desktop computer, and assists in interactively creating a presentation document having the above-described configuration, which will be outlined below.

  The screen 20 is divided into an upper narrow operation pane 21, a left narrow outline pane 22, and a remaining wide editing pane 23.

  In the operation pane 21, menus and buttons for selecting operations on the outline pane 22 and the edit pane 23 are arranged. In the outline pane 22, parts for scrolling this area in the vertical direction and the horizontal direction are arranged.

  When a new document is selected in the operation pane 21 and a blank document is selected as a template, only the (0, 0) page rectangle is displayed in the outline pane 22, and this is selected and displayed in a thick frame. The contents of this page are displayed in the edit pane 23.

  When the last page in the outline pane 22 is the (i, j) page, when the user performs an operation for adding one page in the outline pane 22 to the operation pane 21, the presentation document creation program responds. Then, the (i, j + 1) page is added to the outline pane 22, and the (i, j) page and the (i, j + 1) page are mutually linked.

  When the last page (i, j) in the outline pane 22 is selected and this is shifted to the right by one stage, the presentation document creation program responds with the identifier of the (i, j) page. Change to (i + 1, 0) and change the inter-page mutual link to a one-way link from the (i, j-1) page to the (i + 1, 0) page.

  The program then selects page (i, j-1) in outline pane 22 and places a standard link button to page (i + 1,0) on this page in edit pane 23. The user can change attributes such as the position, design, color, and display name of the button.

  Similarly, when the last page (i, j) page in the outline pane 22 is selected and an operation of shifting it to the left by one stage is performed, the presentation document creation program responds to the above and the above page is displayed. The page identifier is changed so that the page is the next page of the nearest page in the same level as this page, and the page is mutually linked.

  FIG. 4 shows a state before the standard link button is arranged after selecting (1, 2) pages in the outline pane 22 in FIG. 3 and shifting it to the right by one stage.

  When the intermediate page in the outline pane 22 is shifted in the horizontal direction, the page identifier is changed so that the page identifier conforms to the rule similar to that in FIG. The same applies to links and one-way links.

  FIG. 5 is a schematic flowchart showing the processing of the page transition program for causing the display device 17 to display a hierarchical presentation document in accordance with the operation of the input device 16. This process is started by the processor 11 in response to the occurrence of an instruction input event on the touch panel. In the following, the step identification codes in FIG. 5 are shown in parentheses.

  First, as an initialization process, the process of step S10 is executed before the process of FIG.

  (S10) The processor 11 bitmaps the images of at least the current page and the next page, previous page, child page, and parent page (which do not exist) that can be moved from the current page in the buffer area in the DRAM 14. Expand. Also, only in the initialization process, the current page image in the buffer area is transferred to the video RAM in the DRAM 14.

  (S0) If the instruction input event is a swipe operation (LSW) in the left direction on the touch panel, the process proceeds to step S1, and if it is a swipe operation (RSW) in the right direction, the process proceeds to step S2 to the link button. If the touch operation is (TCH), the process proceeds to step S4.

  (S1) The value of j on the current (i, j) page is incremented by 1, and 0 is substituted for the switch SW used in step S9, and the process proceeds to step S3.

  (S2) The value of j on the current (i, j) page is decremented by 1, and 1 is assigned to the switch SW, and the process proceeds to step S3.

  (S3) If page (i, j) exists, the process proceeds to S9, and if not, the process proceeds to step S6.

(S4) The identifier (i, j) of the current (i, j) page that is the connection source page is pushed to the stack area in the DRAM 14. That is, the identifier (i, j) is stored at the address pointed to by the stack pointer SP, and the value of the stack pointer SP is incremented by the number of bytes m of the identifier (i, j). Also, 2 is assigned to the switch SW.

  6A, 6B, and 6E show the stack area after the push operation when transitioning from the connection source page to the connection destination page in FIG. 2B, and FIG. , 0) to the (1, 0) page, after the push operation, FIG. 6B transitions from the current (2, 0) page to the (3, 0) page in FIG. 2B. FIG. 6E shows the state after the push operation when transitioning from the current (1,3) page to the (4,0) page in FIG. 2B.

  (S5) The identifier (i, j) of the current (i, j) page is updated to the identifier of the link destination page (link destination) of the current (i, j) page. For example, in FIG. 2B, if the current page is the (0, 0) page, it is updated to the (1, 0) page. Next, the process proceeds to step S9.

  (S6) If a pop operation on the stack area is possible, that is, if the value of the stack pointer SP is larger than the initial value A0 shown in FIG. 6, the process proceeds to step S8, and if not, the process proceeds to step S7.

  (S7) Since page (i, j) does not exist, the value of j is returned to the previous value. That is, the operation in step S1 or S2 is canceled. Next, the process of FIG.

  (S8) The reverse operation of step S4, that is, popping (i, j) from the stack area and updating the identifier of the current page with this value. Specifically, the value of the stack pointer SP is decremented by m, m bytes of data are taken out from the address pointed to by the stack pointer SP, and this is made the current (i, j). Also, the value 3 is added to the switch SW. Next, the process proceeds to step S9.

FIGS. 6C, 6D, and 6F show the stack area after the pop operation when transitioning from the connection destination page to the connection source page, and FIG. 6C shows the address from the state of FIG. 6B. Contents of A0 + 2m (2
, 0) is read and after the pop operation at the time of transition to the page of the connection source page (2, 0), FIG. 6D shows the contents (1, 1) of the address A0 + m from the state of FIG. After the pop operation at the time of reading and transitioning to the page of the link source page (1, 1), FIG. 6F reads the contents (1, 3) of the address A0 + m from the state of FIG. The state after the pop operation at the time of transition to the page (1, 3) is shown.

  (S9) Transition to the updated (i, j) page. The transition operation on the screen is performed as follows according to the value of the switch SW so as to intuitively understand how the transition is performed.

  When SW = 0, that is, when the user is in the window 30 as shown in FIG. 7A, for example (in FIGS. 7 to 9, the dotted line frame of the window 30 is shown slightly larger). If it is determined in step S0 that the operation of the swipe 31 (LSW) has been performed and an affirmative determination is made in step S3, the next page (1, 1) is placed in the area corresponding to the right of the image of the current page (1, 0) on the video RAM. The image of 1) is transferred from the buffer area and arranged, and during swipe, the window 30 is moved from the current page (1, 0) to the next page (1, 1) side in accordance with the swipe operation. As a result, the current page (1, 0) in FIG. 7A smoothly transitions to the state in FIG. 7B. After the user lifts his / her finger from the screen, the window 30 is further smoothly moved to the right to obtain the state shown in FIG. 7C. Similarly, the window 30 is further smoothly moved to the right, and FIG. ) In the (1,1) page display state.

When SW = 1, that is, when the user performs a right swipe (RSW) operation within the window 30, it is determined in step S0, and if the determination is affirmative in step S3, the image of the current page on the video RAM is displayed. The image on the previous page is transferred from the buffer area and arranged in the area corresponding to the left of the window 30 and the window 30 is moved in the opposite direction.
If SW = 2, that is, if it is determined in step S0 that the user has touched (TCH) the link button 32 in the window 30 as shown in FIG. The image of the link destination page (1, 0) is transferred and arranged from the buffer area in the area corresponding to the upper part of the current page (0, 0), and the page (1, 0) is fixed while the window 30 is fixed. ) Is gradually shifted upward to shift the state from FIG. 8A to FIG. 8B, further to FIG. 8C, and further to FIG. Still in page display state.

  By such an operation, the presenter and the viewer can easily grasp that the transition has been made from the connection source page of the sub-document to the connection destination page of another sub-document.

  When SW = 3, that is, when the user determines that the user has operated the left swipe 31 (LSW), for example, as shown in FIG. The image on the first plane on the RAM is the background color image only, the image on the second plane on the video RAM is the image of the current page (1, 3), and the second plane is on the first plane. The planes are overlapped, the window 30 is fixed on the first plane, and the second plane is moved to the left in accordance with the swipe operation during the swipe. As a result, the current page (1, 3) in FIG. 7A smoothly transitions to the state in FIG. 7B. After the user lifts his / her finger from the screen, the image of the link source page (0, 0) of the current page is transferred from the buffer area and arranged on the first plane, and the second plane is moved downward. Smoothly move to the state of FIG. 7 (C), further move to the state of FIG. 7 (D), and further move to stop in the (0, 0) page display state of FIG. 7 (E). Let

  By such an operation, the presenter and the viewer can easily grasp that the transition from the last page of the sub-document to the connection source page of another sub-document.

  When SW = 4, that is, when the user has operated the right swipe 33 (RSW) as shown in FIG. 10A, for example, it is determined in step S0, and the determination is negative in step S3. The image on the first plane on the RAM is the background color image only, the image on the second plane on the video RAM is the image of the current page (1, 0), and the second plane is on the first plane. The planes are overlapped, the window 30 is fixed on the first plane, and the second plane is moved to the right in accordance with the swipe operation during the swipe. As a result, the current page (1, 0) in FIG. 10A smoothly transitions to the state in FIG. After the user lifts his / her finger from the screen, the image of the link source page (0, 0) of the current page is transferred from the buffer area and arranged on the first plane, and the second plane is moved downward. Smoothly move to the state of FIG. 10 (C), further move to the state of FIG. 10 (D), and further move to stop in the (0, 0) page display state of FIG. 10 (E). Let

  When SW = 5, that is, when it is determined in step S0 that the user has performed a left swipe operation and a negative determination is made in step S3, the image on the first plane on the video RAM is changed to the background color image. The image on the second plane on the video RAM is the current page image, the second plane is superimposed on the first plane, the window is fixed on the first plane, and the first plane is swiped while swiping. 2 plane is moved to the left according to the swipe operation. After the user lifts his / her finger from the screen, the second plane is smoothly moved downward and removed from the window, as in the case of SW = 4.

  Next, the process of step S10 described above is performed to prepare for the next instruction input event occurrence on the touch panel.

  According to this embodiment, in response to a swipe operation on the touch panel, if the next page of the current page does not exist, the connection source page of the current sub-document is displayed on the display device 17, and if the previous page of the current page does not exist. Since the connection source page of the current sub-document is displayed on the display device 17, the presenter and the viewer can easily grasp the transition from the last page or the first page of the sub-document to the connection source page of another sub-document. There is an effect that can be.

  In addition, when transitioning to the source page, the current page that is the destination page is superimposed on the source page, and the current page is opposite to the slide direction when the destination page is the destination. The presenter and viewers transition to the source page by reducing the display area of the current page while sliding in a direction perpendicular to the sliding direction when the page transitions in the same sub-document. Thus, there is an effect that it is possible to more easily grasp the transition from the last page or the first page of the sub-document to the connection source page of another sub-document.

  Further, by a simple push / pop operation regardless of the hierarchical structure, the user does not need to perform an operation of placing a button embedded with a link indicated by a dotted line with an arrow in FIG. Is simplified, and this can prevent the document structure from becoming complicated.

  FIG. 11 is a schematic block diagram showing a hierarchical structure of a presentation document according to the second embodiment of the present invention.

  In this document, sub-document SUB2 is composed of pages (2, 0) to (2, 4) connected in series, and is linked from page (1, 1) to page (2, 1) of sub-document SUB1. . For example, pages (2, 1) to (2, 4) are more detailed than pages (2, 1) to (2, 0), depending on the degree of viewer recognition and time margin. , (2,1) to (2,4) pages or (2,1) to (2,0) pages are selectively explained.

  In addition, two link buttons are arranged on the (2,1) page, and are linked to the (3,0) page and the (3,1) page, respectively. In this case, for example, by selectively touching the link button according to the degree of recognition of the viewer and the degree of time margin, the transition is made to the (3, 0) page or the (3, 1) page.

  Further, the (4, 0) page of the sub-document SUB4 includes a program in which two link buttons are arranged and a page is dynamically generated. The program responds to the pressing of one of the buttons, The (5, 0) page is dynamically generated, and the (6, 0) page is dynamically generated in response to pressing of the other button. On the (5, 0) page and the (6, 0) page, a link button to the (4, 0) page is arranged.

  Other points are the same as in the first embodiment.

  In the above, preferred embodiments of the present invention have been described. However, the present invention includes various other modifications, and those using other configurations for realizing the functions of the above-described components can be used by those skilled in the art. Other configurations that would come from these configurations or functions, if any, are also included in the present invention.

  For example, in step S7 in FIG. 5, the setting may be changed so as not to accept the event, and the program may be terminated.

  Alternatively, the left (right) swipe operation may be replaced with an operation of touching the left (right) side of the page, clicking with the mouse, or pressing the left (right) direction key.

  In addition, a button for returning to the connection source page may be arranged on an intermediate page in the sub-document, and a transition to the connection source page may be performed by performing a pop operation in response to the touch of this button.

  The sub-document to be displayed may be a page in which only images are connected in series.

  Further, a configuration in which the push and pop operations are not performed, for example, step S4 in FIG. 5 is omitted. In step S6, a link to a page of the current subdocument is searched from pages in other subdocuments. If it is determined whether or not this link exists and an affirmative determination is made, the configuration may be such that (i, j) is updated with the identifier of the page on which this link exists in step S8. In addition, when creating a presentation document, a dotted line link with an arrow shown in FIG. 2B may be created, and the search may be omitted.

  The link may be a link on a list structure. For example, the page-to-page connection as shown in FIG. 2B is expressed in a list structure, and in the page transition program, the current page is made to correspond to the position on the list structure, including the transition to the link source page. A configuration in which the list structure is traced to transition between pages may be employed. In this case, the page identifier (i, j) on the list structure is also given to the corresponding page of the document.
