Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hypermedia system and a hypermedia document creating / editing method, and more particularly, to placing a multimedia document on a plurality of cards,
The present invention relates to a hypermedia system that handles a hypermedia document that can dynamically associate information in the document by defining links between the cards, and a method of creating / editing the hypermedia document.

[0002]

2. Description of the Related Art In recent years, there are many tools for displaying or creating hypermedia documents on a computer such as an electronic manual and an electronic book.

Hypermedia documents are characters, moving images,
Multimedia documents that allow mixed audio, images, etc.
Irrespective of the document structure defined by the conventional concept of lines and pages, by arranging the information contained therein on multiple cards, one information can be viewed from related information in multiple directions and other information can be viewed. To provide higher-dimensional information by dynamically connecting with.

At present, such hypermedia documents are not only used for digitizing books such as the above-mentioned electronic manuals and electronic books, but are also being applied to CAI systems and expert systems.

[0005] Such a hypermedia document usually has a stack structure composed of a plurality of cards, and the cards related to each other are linked by some means.

Conventionally, when creating a stack,
The user himself had to define a link button from one card to a card related to that card and associate the cards with each other.

However, since the amount of information is large and the links between the information are complicated, setting the link information is a labor-intensive work. Further, it is necessary to refer to the created hypermedia document while turning the cards one by one by clicking the link button arranged on the card with a mouse or the like. For this reason, when it is desired to switch from a specific card to a related card for display, it may be necessary to flip through a plurality of cards before the target card is reached, and there is a drawback that it takes time to search.

Especially at seminars, education, various presentations,
In the process of creating a hypermedia document for a presentation to be used as a substitute for an OHP or a slide, it is necessary to confirm what kind of card is used in an existing hypermedia document in order to decide a card to be used in the presentation. May occur.
In this case, it is necessary to check the contents of the cards while flipping the cards one by one, but this work is very troublesome and troublesome for the user.

Even when the card to be used is determined, it is usually necessary to change the link structure of the card in accordance with the content and time of the presentation. In this case, the user himself / herself has to perform an operation of connecting the link buttons arranged on the related card. In addition, when giving a presentation, the presentation time (presentation execution time) is usually specified in advance, so it is necessary to edit the hypermedia document so that the card reproduction by the computer is completed within the presentation time. . Therefore, it is very difficult to create a hypermedia document for presentation.

[0010]

As described above, conventionally, it is necessary to refer to each card by flipping the cards one by one by clicking the link button arranged on the card with a mouse or the like. When creating a hypermedia document for presentation by diverting the card used in the document, work to check the contents of the card used in the existing hypermedia document and make sure that it fits within the presentation time. There is a drawback in that it is necessary to select cards and redefine links, which requires a lot of time and effort.

The present invention has been made in view of the above circumstances, and makes it possible to easily execute card confirmation, card selection operation, etc. for creating a presentation document in consideration of the presentation time. It is an object to provide an excellent hypermedia system and a hypermedia document creating / editing method.

Means and Actions for Solving the Problems
When a scenario information is specified by an input command in a hypermedia system that creates and edits a hypermedia document consisting of multiple cards in which text or image information is placed and links are defined for each card, the card A means for displaying a scenario creation screen including a time scale for defining a playback time and displaying a list of a plurality of cards constituting the hypermedia document on the screen, and a time for each of the cards on the scenario creation screen. A means for creating scenario information for defining a card display order and a display switching time at the time of playing a card by moving and rearranging the scale, and at the time of playing the card, the plurality of cards are created according to the created scenario information. Card playback means that switches and displays in order Characterized by comprising.

In this hypermedia system, when a hypermedia document is edited to newly create a hypermedia document for presentation, for example, the scenario creation function is selected by the user from the edit menu displayed on the screen. Then, a command for instructing the creation of scenario information is input. In response to this input command, a scenario creation screen including a time scale is displayed, and a list of all cards in the hypermedia document is displayed on the screen. Therefore, it is possible to confirm at a glance what kind of card is used in the hypermedia document.

Then, on the scenario creation screen, by moving the cards to be used on the time scale and rearranging them, scenario information for defining the card display order and the display switching time at the time of playing the cards is automatically created. It During reproduction of the presentation document, a plurality of cards are sequentially switched and displayed according to the created scenario information.

In this case, the cards may be automatically switched in accordance with the display switching time of the scenario information, or a command for designating the next card may be input by a user's button operation or the like and switched according to the command. good. When switching by command input, based on the display switching time specified by the scenario information,
A progress status is displayed on the screen showing whether the progress is behind or ahead of schedule.

Therefore, an existing hypermedia document or the like can be read as an input document from a disc or the like, and can be easily converted into a hypermedia document for presentation in consideration of the presentation time. The cards used and the links can be redefined automatically.

Further, the card switching timing can be automated by the display switching time set on the time scale, and the presenting status can be supported by displaying the progress status on the screen when the card is manually turned. Becomes

Further, according to the present invention, in a hypermedia system for creating / editing a hypermedia document composed of a plurality of cards in which text or image information is arranged and link relationships are defined with each other, scenario information is input by an input command. And a means for displaying a list of a plurality of cards constituting the hypermedia document on a screen for displaying a scenario creation screen including a time scale for defining a card playing time, and the scenario. A means for creating scenario information for defining the card display order and the display switching time at the time of playing a card by moving and rearranging each of the cards on the creation screen and arranging them on the time scale. One or more cards that are key among multiple cards A means for setting key card information in the scenario information by designating, and a plurality of cards are sequentially switched and displayed according to the created scenario information when playing the card, and a command for designating the next key card is input. And a card reproducing means for switching the display to the first key card following the currently displayed card according to the key card information.

In this hypermedia system, a card, which is particularly important for presentation, can be designated as a key card when creating scenario information. When a command for designating the next key card is input during card reproduction, the current card display is forcibly terminated and the display is switched to the first key card following it. This allows you to skip the display of less important cards and call up important ones immediately, for example, if the presentation is delayed, and adjust the time to finish the presentation in time. .

As shown in the figure, each card is composed of a title area 201, a paragraph area 202, and a link button area 203 arranged on the card mount. The title area 201 serves as the title of the card itself, and the content of the "headline" of the document corresponding to the card is placed here. In the paragraph area 202, the body part of the paragraph corresponding to the “heading” is arranged. The link button area 203 is an area for defining a link with another card, and the title of the linked card is arranged as a label in this area.

Next, with reference to FIG. 4, a specific description will be given of how a document structured in a tree structure is assigned to a card. Here, as shown in FIG. 4 (A), the document is classified into three nodes, which are composed of headings "Introduction", "Specifications", and "Summary" and paragraphs subordinate thereto. Suppose that.
In addition, in the paragraph of “specification”, a figure is referred to in the text, whereby the reference part (text) and the reference body (figure) referred to by the reference part (text) are combined.

The document structured as shown in FIG.
It is converted into a stack as shown in FIG. This stack is composed of a table of contents card C1, a card C2 corresponding to a node (first), a card C3 corresponding to a node (specification), and a card C4 corresponding to a node (collective).

The table-of-contents card C1 is created in order to immediately call the target card.
In 1, the headings of all cards (here, cards C2 to C4) are centrally managed.

That is, the table-of-contents card C1 is assigned with three link buttons L1 to L3 for realizing links between the card C1 and the cards C2 to C4, respectively, and the link button L1 has the links. The heading "Introduction" of the preceding card C2, the heading "Specification" of the linking card C3 on the link button L2, and the heading "Summary" of the linking card C4 on the link button L3 are respectively arranged as labels. . Further, in the specification card C3, a link button L4 for realizing a reference link with a drawing is assigned, and "drawing" is arranged as a label there.

Each of these cards also holds a link (bidirectional) to the linked card, and can return from the link destination to the link source. Further, according to the route (contents card C1, card C2, card C3, card C4, contents card C1), it also holds a link to the next card. The data structure of each of these cards C1 to C4 is shown in FIG.
Shown in

As shown in FIG. 5, each card includes title information, body information, and link button information. For the table of contents card C1, title information and text information are undefined, and for the link button information, a pointer and a script (go to “Introduction”) for linking with the card C2, and a link with the card C3. Pointer and script (go to
"Specification"), and a pointer and a script (go to "end") for linking with the card C4 are defined.

For the card C2, the link button information is undefined, and the title information of "Introduction" and the body information including the pointer indicating the content file holding the text document corresponding to "Introduction" are defined. .

For the card C3, the title information of "specification" and the text information including the pointer indicating the content file holding the text document corresponding to the "specification" are defined, and the link button information includes the text in the text. A pointer and a script (go to “figure”) for linking with an external file holding the figure referred to by are defined.

For the card C4, the link button information is not defined, and the title information of "End" and the body information including the pointer indicating the content file holding the text document corresponding to "End" are defined. ing.

As described above, in the hypermedia system of FIG. 1, the hypermedia document is created by automatically defining the card link according to the result of the structural analysis of the document. Further, the created hypermedia document is stored in the file device 13 as a card file.

Next, the scenario creating function of the hypermedia system shown in FIG. 1 will be described with reference to FIGS. 6 and 7 show the scenario creation screen provided by the hypermedia system of FIG. 1, and FIG. 8 shows the procedure for displaying the scenario creation screen.

To execute the scenario creation function, as shown in FIG. 6, the edit icon 102 is selected from the menu bar 101 on the screen by operating the mouse to display the edit function submenu 103. 103
It is performed by selecting the item 104 of the scenario creating function from among the items by operating the mouse.

As a result, the command for instructing the scenario creation is sent from the input unit 11 of FIG. 1 to the hyper editor 15, and the scenario creation process is performed as follows according to the procedure of FIG.

First, a time scale 1 showing time on the horizontal axis
05 is displayed on the screen as shown in FIG. 6 (step S101). Next, the cards constituting the stack to be displayed as a list are read from the card file of the file device 13, and each of these cards (including the text document arranged on the card) is reduced in size on the memory (step S102). Then, after serial numbers are assigned to the cards in the link order according to the logical description file 131, the cards are arranged in the numerical order as shown in FIG. 6 and displayed as a list as scene icons on the screen (steps S103 and S104). By this card list display,
It is possible to check at a glance what kind of card is used in the hypermedia document without turning the cards one by one.

Next, the scene icon used for the presentation is selected by operating the mouse or the like, moved to the time scale 105, and arranged on the time scale 105 according to the time series of the order of the actual presentation (step S105). Step S105
This process is repeatedly executed until the user inputs a scenario creation end command, and the selected scene icons are sequentially arranged on the time scale 105 (steps S105 and S106). This is shown in FIG.

FIG. 7 shows one of the scenes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 among the 12 scene icons.
It is shown that 0 scene icons were selected and they were placed on the 60 minute time scale. The time of the entire time scale can be arbitrarily specified.

When it is notified that the arrangement of all the scene icons is completed by the user's keyboard or mouse operation (step S106), the card is displayed according to the arrangement order of the scene icons on the time scale 105 and the arrangement position of each scene icon. Scenario information that defines the switching order and switching time is created (step S10).
7).

In the card reproduction mode, the card reproduction display unit 157 refers to the scenario information, and the cards are switched and displayed according to the scenario information. In this case, the card switching may be executed in response to the user's operation, or may be automatically switched according to the switching time defined by the scenario information.

When switching the cards according to the user's operation, the presenter can switch the cards by operating the next card button arranged on the card or a predetermined key. Further, in this case, the switching time defined by the scenario information is used to notify the presenter of the progress status (advance or delay) of the presentation.

When creating a scenario, it is possible to create key information in the scenario information and incorporate it into the scenario information. The key information specifies an important scene in a series of scenes arranged in the order of the scenario.

That is, as shown in the flow chart of FIG. 10, in a series of scenes arranged in the order of the scenario, the presenter selects a scene icon that is judged to be particularly important in the presentation with the mouse or the like. By doing so (step 201), it can be designated as a key scene. This state is shown in FIG.

FIG. 9 shows a state in which among the 10 scene icons arranged on the time scale 105, scenes 1, 3, 4, 5, 8 and 10 are selected as key scenes. ing.

The information of the key scene designated in this way is incorporated into the scenario information as key information (step S202). Next, with reference to FIG. 11 to FIG. 13, a description will be given of processing in the case of displaying the progress status of the presentation on the screen by using the switching time defined by the scenario information.

FIG. 11 shows an example of a display screen at the time of presentation. Thus, an icon indicating whether the progress status of the presentation is ahead of schedule or behind the schedule is displayed at the screen corner of the display screen. One black circle icon indicates a one-minute delay, two black circle icons indicate a two-minute delay, and three black circle icons indicate a three-minute delay. Also, one white circle icon indicates one minute advance, two white circle icons indicate two minutes advance, and three white circle icons indicate three minutes advance.

As a result, the presenter can accurately grasp the progress without being aware of the listening. The display process of the icon indicating the progress status is performed according to the procedure of FIG.

During the presentation, the time management mechanism of the card playback / display unit 157 displays the time (Tc) elapsed from the presentation start time to the present and the scheduled start time of the scene next to the currently displayed scene (Tc). t
s) (difference time td) (step S3)
01-S304). For example, as shown in FIG. 13, the time elapsed from the start time of the presentation to the present is Tc = 18 minutes and 20 seconds, and the scheduled start time of the scene next to the currently displayed scene is ts = 15 minutes. In the case of, it is recognized that the shift time of −3 minutes and 20 seconds (delay of 3 minutes and 20 seconds) occurs.

Next, the card reproduction / display unit 157 rounds the deviation time td to a preset unit time (for example, 1 minute unit) (step S305), and associates 1 unit time with one icon, As described with reference to FIG. 11, the deviation time td is graphically displayed on the screen (step S30).
6). In the example of FIG. 13, three black circle icons are displayed at the left corner of the screen.

Next, the card switching process using the key information will be described with reference to FIGS. 14 and 15. The card playback display unit 157 is for moving to the important scene [NEXT], which is a key when the presentation is executed.
The [PREV] button is constantly displayed on the screen as shown in FIG. 14 (step S401). When the presenter presses the [NEXT] button during the presentation,
The currently displayed scene is forcibly terminated and the screen is switched to the next key scene closest to the current scene (steps S402 and S403).

For example, as described with reference to FIG. 9, among the 10 scene icons, scenes 1, 3, 4, 5, 8, 10
If is set as a key scene, pressing the [NEXT] button while scene 6 is displayed
As shown in FIG. 14, scene 6 is forcibly ended,
The screen is switched to scene 8, which is the next key closest to scene 6.

When the presenter presses the [PREV] button during the presentation, the currently displayed scene is forcibly terminated and the screen is switched to the scene of the previous key closest to the current scene ( Steps S404 and S405).

As a result, when the progress time of the presentation is delayed, the display of the less important scenes is omitted and an important scene is called, and when the progress time is advanced, the previous important scene is displayed. It is possible to adjust the time such as returning to.

As described above, in the hypermedia system of this embodiment, attention is paid to the fact that the text document included in the input document usually has some logical structure, and the hypermedia document is based on that logical structure. Is created and edited, an existing document created by a word processor or the like can be read as an input document from a disk or the like, and it can be easily converted into a hypermedia document.

When a card used in the created hypermedia document is diverted to create a new hypermedia document for presentation, all cards in the hypermedia document are listed on the screen. By arranging the displayed and listed cards on the time scale, scenario information including time information can be automatically created, and various support regarding the presentation time can be performed using the time information. .

[0072]

As described above, according to the present invention, it is necessary to perform an operation for creating or editing a hypermedia document, especially for creating a new document for presentation by using an existing card. The card confirmation operation and the link redefinition operation can be easily performed while considering the presentation time, and a hypermedia system with excellent operability can be realized.
