Electronic device providing an improved page switching function when running a slide show for a presentation document and its operating method

The present invention relates to an electronic device that provides an improved page switching function when a slide show of a presentation document is executed, and an operating method thereof.

Recently, as computers, smart phones, tablet PCs, etc. have been widely spread, various types of electronic document-related programs have been released that enable users to view, create, and edit electronic documents using these electronic devices.

These electronic document-related programs include a word processor supporting basic document creation and editing, a spreadsheet assisting data input, arithmetic operation, and data management, and a presentation program assisting a presenter's presentation.

Among the above-mentioned electronic document-related programs, a presentation program is a program that assists a user to create a presentation document suitable for presentation in a terminal device, and inserts various objects such as figures and tables on the editing screen of the presentation document. It provides a document creation function that allows users to view documents and a slide show function that allows completed documents to be displayed on the entire screen.

In general, when a slide show is executed in an existing presentation document, pages constituting the presentation document are sequentially converted according to page numbers.

In this regard, generally, when users create a presentation document, they divide the main topic such as 'introduction, body, conclusion', etc., and then arrange the contents of sub-topics subordinate to each main topic in each main topic. tend to write Therefore, considering the tendency of users to create documents, it is possible to introduce a method of dividing and managing pages constituting a presentation document into a main page according to a main theme and sub pages subordinate to each main page.

In this way, if the presentation document is divided into predetermined main pages and subpages according to each main page and managed, when a user executes a slide show, page switching for subpages is sequentially performed for each main page, When the conversion of each subpage is completed, subpages for the next main page are switched, so that a more systematic page conversion according to a subject can be performed, so that more accurate content can be delivered to the audience.

In addition, if pages are managed with main pages and sub-pages corresponding to each main page in this way, if a situation occurs where the presentation time is insufficient when a user runs a slide show, sub-pages are omitted and pages for each main page In the sense that switching can be performed, rapid subject changes may be possible.

Therefore, it is possible to increase user convenience by dividing a presentation document into main pages and subpages corresponding to each main page, and supporting the user to perform page transitions of various patterns when running a slide show based on this. A study on the technology is needed.

The present invention supports generation of a plurality of main pages and at least one sub-page corresponding to each main page in a presentation document, and at least one sub-page corresponding to the plurality of main pages and each main page when a slide show is executed.

When a slide show execution command for the presentation document is applied from the user, the slide show executor 113 displays a first main page to which a first main page number is assigned among the plurality of main pages. displayed on the

When a page switching command for the presentation document is applied from the user after the first main page is displayed on the screen, the page switching unit 114 configures the plurality of main pages constituting the presentation document and each main page. For at least one subpage dependent on a page, page switching is performed according to operating conditions (A) to (B) shown in Table 1 below.

operating condition (A) If the page switching command is applied once in a situation where a first main page, which is one of the plurality of main pages, is displayed on the screen, each time the page switching command is applied, the first main page 1 At least one subpage subordinate to the main page is switched one by one according to the subpage number assigned to each subpage and displayed on the screen. (B) When the page switching command is applied while a subpage to which the last subpage number is assigned among at least one subpage subordinate to the first main page is being displayed on the screen, the first main page The second main page having the number next to the main page number assigned to is switched and displayed on the screen.

Hereinafter, operations of the slide show execution unit 113 and the page switching unit 114 will be described with reference to FIG. 3 as an example.

First of all, the slide show execution unit 113, when a slide show execution command for the presentation document 200 is applied to the electronic device 110 from the user, 'main page 1 201, main page 2 202, Among main page 3 (203) and main page 4 (204), 'main page 1 (201)' to which the first main page number '1' is assigned can be displayed on the screen.

In this way, after the 'main page 1 (201)', which is the first main page, is displayed on the screen by the slide show executor 113, a page conversion command for the presentation document 200 from the user is sent to the electronic device 110. ), the page switching unit 114, whenever a page switching command is applied, subpages subordinate to 'main page 1 (201)' based on the operating condition (A), ' Subpage 1(211), Subpage 2(221), Subpage 3(231)' are switched in order of 'Subpage 1(211), Subpage 2(221), Subpage 3(231)' can be displayed on the

At this time, if 'subpage 3 (231)', the last subpage among subpages subordinate to 'main page 1 (201)', is displayed on the screen, a page switching command from the user is electronically transmitted. When additionally applied to the device 110, the page switching unit 114 displays 'Main Page 2 (202)', which is the next main page of 'Main Page 1 (201)', on the screen according to the operating condition (B). It can be displayed by switching the image.

In this way, after the 'main page 2 (202)' is displayed on the screen, when a page switching command is additionally applied to the electronic device 110 from the user once again, the page switching unit 114 receives each page switching command Whenever it is applied, 'Subpage 4 (212) and Subpage 5 (222)', which are subpages subordinate to 'Main Page 2 (202)', are changed to 'Subpage 4 (212)' according to the above operating condition (A). ), subpage 5 (222)', and displayed on the screen.

After that, if a page switching command is applied to the electronic device 110 again from the user, the page switching unit 114 may switch the screen to 'main page 3 203' according to the operating condition (B), Additionally, when a page switching command from the user is applied to the electronic device 110, the page switching unit 114 sequentially switches subpages subordinate to the 'main page 3 203' according to the operating condition (A). so that it can be displayed on the screen.

In this way, the page switching unit 114 whenever a page switching command is applied from the user, as in the direction of the arrow shown in FIG. 3, 'main page 1 201 -> sub page 1 211 -> sub page Page 2 (221) -> Sub Page 3 (231) -> Main Page 2 (202) -> Sub Page 4 (212) -> Sub Page 5 (222) -> Main Page 3 (203) -> Sub Page 6 Page conversion can be performed in the order of (213) -> sub page 7 (223) -> main page 4 (204) -> sub page 8 (214) -> sub page 9 (224).

At this time, according to an embodiment of the present invention, the electronic device 110 may further include a page inversion unit 115 .

After a slide show execution command for the presentation document is applied by the user, the page inversion unit 115 displays a first subpage, which is any one of at least one subpage subordinate to the first main page, on the screen. In a situation in which the first subpage displayed on the screen is displayed on the screen, when a reverse conversion command to the previous page for the presentation document is applied from the user, the main page allocated to the first main page The third main page having the previous main page number of the page number is switched and displayed.

In this regard, referring to FIG. 4, the operation of the page inversion unit 115 will be described as follows.

First, after a slide show execution command for the presentation document 200 is applied to the electronic device 110 by the user, the first subpage currently displayed on the screen is 'subpage 6 (213)'. Let's assume

In this way, in a situation where the 'subpage 6 (213)' subordinate to the 'main page 3 (203)' is displayed on the screen, a reverse conversion command from the user to the previous page for the presentation document (200) is displayed. When applied to the electronic device 110, the page inversion unit 115 converts 'sub page 6 213' displayed on the screen to 'main page 3 203' as shown in FIG. 4 . It can be displayed by switching to 'main page 2 202', which is a main page having '2', which is the previous main page number of '3', which is the main page number assigned to .

In this way, after the screen is switched and displayed to 'main page 2 (202)', when a reverse conversion command is additionally applied to the electronic device 110 from the user, the page reverse conversion unit 115 as shown in FIG. As shown in the figure, the 'main page 2 (202)' displayed on the screen can be additionally reversed to the 'main page 1 (201)' having the previous main page number '1'.

As a result, when a page inversion command is applied from the user while a specific subpage is being displayed on the screen, the page inversion unit 115 does not reverse the previous page in units of subpages, but returns to the immediately previous main page. You can reverse the page. That is, the page inversion unit 115 may invert a page to a previous page in units of main pages according to a page inversion command applied by a user.

Also, according to an embodiment of the present invention, the electronic device 110 may further include a main page conversion unit 116 .

After a slide show execution command for the presentation document is applied by the user, the main page switching unit 116 converts the first subpage, which is any one of at least one subpage subordinate to the first main page, to the main page. In a situation where it is being displayed on the screen, if a main page conversion command for the presentation document is applied from the user, the main page number assigned to the first sub-page displayed on the screen is assigned to the first main page. Switches to the second main page having the next main page number of and displays it.

In this regard, referring to FIG. 5, the operation of the main page switching unit 116 will be described as follows.

First, after a slide show execution command for the presentation document 200 is applied to the electronic device 110 by the user, the first subpage currently displayed on the screen is 'subpage 4 (212)'. Let's assume

In this way, in a situation where the 'subpage 4 (212)' subordinate to the 'main page 2 (202)' is displayed on the screen, a command to switch to the main page for the presentation document 200 from the user is sent to the electronic device ( 110), the main page switching unit 116 allocates the 'subpage 4 212' displayed on the screen to the 'main page 2 202' as shown in FIG. It can be displayed by switching to 'main page 3 (203)', which is a main page having '3', which is the next main page number of '2', which is the main page number.

In this way, after the screen is switched to 'main page 3 (203)' and displayed, when a main page switching command is additionally applied to the electronic device 110 from the user, the main page switching unit 116 is shown in FIG. 5. As shown in the figure, the 'main page 3 (203)' displayed on the screen can be additionally converted to the 'main page 4 (204)' having the next main page number '4'.

As a result, when a main page switching command is applied from the user in a situation where a specific subpage is displayed on the screen, the main page switching unit 116 does not switch to the next page in units of subpages, but to the immediately following main page. You can turn pages. That is, the main page switching unit 116 may convert a page to a subsequent main page in units of main pages according to a main page switching command applied by a user.

According to an embodiment of the present invention, the electronic device 110 may further include a region divider 117, a ratio calculator 118, a region selector 119, and a main page display unit 120.

After a slide show execution command for the presentation document is applied by the user, the area divider 117 displays the first subpage, which is any one of at least one subpage subordinate to the first main page, on the screen. When a simultaneous display command of the main page is applied from the user, the first subpage is divided into rectangular regions having a predetermined size, and n (n is a natural number equal to or greater than 2) divided regions. create them

The ratio calculation unit 118 checks whether there is an inserted object in the first subpage, and if it is confirmed that at least one first object is inserted in the first subpage, for each of the n divided areas , A ratio occupied by an area of a portion overlapping the at least one first object on the first subpage is calculated.

The area selector 119 selects a split area calculated with the smallest ratio among the n split areas as a simultaneous display area for displaying a main page.

When the simultaneous display area is selected, the main page display unit 120 additionally displays the first main page in the simultaneous display area on the first sub-page displayed on the screen.

Hereinafter, with reference to FIGS. 6, 7, and 8, operations of the region divider 117, the ratio calculation unit 118, the region selector 119, and the main page display unit 120 will be described in detail by way of example. I'm going to do it.

First, the first main page, which is any one of the plurality of main pages, 'Main Page 1 (201), Main Page 2 (202), Main Page 3 (203), and Main Page 4 (204)' is called 'Main Page'. 3 (203)', and any one of 'subpage 6 (213) and subpage 7 (223)', which are at least one subpage subordinate to the 'main page 3 (203)', which is the first main page. , the first subpage is called 'subpage 7 223', and as shown in FIG. 6, three objects 611 and 612 are included in , 613) is inserted.

Here, an object means an item such as text, figure, table, image, etc. that can be inserted into an electronic document such as a presentation document.

In this case, after a slide show execution command for the presentation document 200 is applied to the electronic device 110 by the user, at least one sub-subordinate to the 'main page 3 203', which is the first main page, is displayed. In a situation where the first subpage 'Subpage 7 (223)', which is any one of the pages 'Subpage 6 (213) and Subpage 7 (223)', is displayed on the screen, the main page from the user When the simultaneous display command of is applied to the electronic device 110, the region divider 117 divides the 'subpage 7 223' into rectangular regions of a preset size, thereby generating 12 divided regions. .

Then, the ratio calculation unit 118 may check whether there is an object inserted into the 'subpage 7 (223)'. In relation to this, in the figure shown in FIG. 7, since three objects 611, 612, and 613 are inserted into 'subpage 7 223', the ratio calculation unit 118 converts the at least one first object to , three objects 611, 612, and 613 can be identified.

Then, the ratio calculation unit 118 determines the ratio occupied by the area of the portion overlapping with the at least one first object 611, 612, 613 on the 'subpage 7 223' for each of the 12 divided areas. can be computed.

In this regard, in the figure shown in FIG. 7 , the divided area 614 indicated by reference numeral 614 among the 12 divided areas does not overlap with at least one first object 611, 612, and 613. , the ratio calculation unit 118 may calculate the ratio for the divided area 614 as '0%'. In addition, since each of the remaining 11 divided regions excluding the divided region 614 among the 12 divided regions has an overlapping portion with at least one first object 611 , 612 , and 613 , the ratio calculation unit 118 divides The ratio for each of the remaining 11 divided regions excluding the region 614 may be calculated as a value greater than '0%'.

Then, the area selector 119 may select the partition area 614 whose ratio is calculated as '0%', which is the smallest value among the 12 divided areas, as a simultaneous display area for displaying the main page.

In this way, when the divided area 614 is selected as the simultaneous display area for displaying the main page by the area selection unit 119, the main page display unit 120 displays the area displayed on the screen as shown in FIG. 8 . 'Main page 3 (203)' can be additionally displayed in the simultaneous display area 614 on 'sub page 7 (223)'.

In this way, when the 'main page 3 (203)' is additionally displayed in the simultaneous display area 614 on the 'sub page 7 (223)', observers watching the slide show view the 'sub page 7 (223)' through the screen. 223)', you can also see 'Main Page 3 (203)', which is the main page to which 'Sub Page 7 (223)' is subordinated, so you can understand the contents of 'Sub Page 7 (223)' more easily and quickly. You will be able to.

At this time, according to an embodiment of the present invention, the region selection unit 119 may include a separation distance calculation unit 121 , an average calculation unit 122 , and a selection unit 123 .

The separation distance calculation unit 121 determines, when there are two or more divided regions whose ratio is the smallest among the n divided regions, the center point of each of the two or more divided regions and the at least one first divided region. Calculate the separation distance between the center points of each object.

For each of the two or more divided regions, the average calculation unit 122 calculates an average value of a separation distance between a center point of each of the two or more divided regions and a center point of each of the at least one first object. do.

The selector 123 selects a divided area obtained by calculating the largest average value among the two or more divided areas as the simultaneous display area.

Hereinafter, with reference to FIGS. 9, 10, and 11, operations of the separation distance calculation unit 121, average calculation unit 122, and selector 123 will be described in detail, for example.

First, the first main page, which is any one of the plurality of main pages, 'Main Page 1 (201), Main Page 2 (202), Main Page 3 (203), and Main Page 4 (204)' is called 'Main Page'. 3 (203)', and any one of 'subpage 6 (213) and subpage 7 (223)', which are at least one subpage subordinate to the 'main page 3 (203)', which is the first main page. , the first subpage is referred to as 'subpage 7 223', and as shown in FIG. ) is inserted. In addition, when a simultaneous display command of the main page is applied to the electronic device 110 from the user, the first subpage 'subpage 7 223' is displayed in a rectangular area having a preset size by the area divider 117. Assume that 12 divided areas are created as shown in FIG.

At this time, the ratio calculation unit 118 can identify two objects 911 and 912 as at least one first object inserted into the 'subpage 7 223', which is the first subpage, and A ratio occupied by an area of a portion overlapping at least one first object 911 or 912 on the 'subpage 7 223' may be calculated for each of the divided areas.

In relation to this, in the figure shown in FIG. 10 , the divided areas 913 and 914 indicated by reference numerals 913 and 914 among the 12 divided areas include at least one first object 911 and 912. Since there is no overlapping portion, the ratio calculation unit 118 may calculate the ratio as '0%' for each of the divided areas 913 and 914 . In addition, since each of the remaining 10 divided regions excluding the divided region 913 and the divided region 914 among the 12 divided regions has an overlapping portion with at least one first object 911 and 912, the ratio calculation unit In (118), the ratio for each of the remaining 10 divided regions excluding the divided region 913 and the divided region 914 among the 12 divided regions may be calculated as a value greater than '0%'.

At this time, since there are two or more divided areas among the 12 divided areas, the split area calculated as '0%', which is the smallest value of the ratio, is the split area 913 and the split area 914, the separation distance calculation unit 121 also As shown in the dashed-dotted line shown in FIG. 11, a separation distance between the center points of each of the divided areas 913 and 914 and the center points of each of the at least one first object 911 and 912 may be calculated.
