DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for presenting plural information, and more particularly to a method and apparatus for presenting plural information in a cooperative manner via a communication line such as the Internet.

[0002]

2. Description of the Related Art With the development of information communication infrastructure in recent years, it has become possible for a personal computer (PC) to participate in a network as an information terminal to transmit and obtain various information. . Recently, the Internet has been known as a network that can be used easily, and information can be easily exchanged only by preparing a PC including a communication device, that is, bidirectional information exchange is possible. By taking advantage of this network, it is becoming possible to take seminars and lectures via a network such as personal computer communication or the Internet, even if the user is at a remote location.

When attending a lecture in a remote place, the user views the image information and the audio information of the lecture through a network, and the user selects a desired lecture. At this time, in general, a desired course can be selected without being restricted by time. Then, from the side where the course is held, image information and audio information are presented so as to be viewable, and the user views the presented information using a personal computer or the like, thereby individually viewing the desired course. When a lecture is held via such a network, it is necessary to present a plurality of pieces of information in a coordinated manner.

[0004]

However, when a plurality of pieces of information are presented in a cooperative manner, there is a case where it is desired to shift to an arbitrary position in a time series with reference to one of the pieces of presentation information. For example, in a course that a user is attending, there may be a request that the user wants to quickly move to a desired lecture content while referring to the lecture content displayed during the lecture. For this purpose, it is necessary to predict and consider the intention of the user in advance. However, it is not practical to predict and consider the intention of the user for all information in advance.

An object of the present invention is to provide a method and an apparatus for presenting a plurality of pieces of information that can easily and with a high degree of freedom and present a plurality of pieces of information in a coordinated manner. is there.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for presenting a plurality of pieces of information whose presentation contents change in a time-series manner through a communication line in a mutually cooperative manner. And so that each is presented in cooperation,
The plurality of pieces of presentation information are transmitted to the operation-side terminal via a communication line, and the time series of the presentation information belonging to any one of the pieces of presentation information specified by the operator and received through the communication line are transmitted. Identifying information corresponding to a specific position, generating new presentation information so as to be presented in a coordinated manner in accordance with the identified identification information, and transmitting the generated new presentation information via a communication line. To the operation side terminal.

In the present invention, a plurality of pieces of presentation information whose presentation content changes in a time-series manner are presented in cooperation with each other via a communication line such as the Internet. The plurality of pieces of presentation information are transmitted to the operation side terminal via the communication line so as to be presented in a coordinated manner. This allows the operating terminal to view a plurality of pieces of presentation information presented in cooperation with each other. Thereafter, the operator specifies a shift to an arbitrary position in a time series. For this designation, identification information corresponding to a time-series position in the presentation information is indicated. The identification information corresponding to the time-series position in the presentation information belonging to any one of the presentation information specified by the operator and received via the communication line is specified. Then, new presentation information is generated so as to be presented in cooperation with each of the identified identification information, and the generated new presentation information is transmitted to the operation-side terminal via the communication line. This makes it possible to easily and quickly provide presentation information of the transition position intended by the operator.

[0008] The presentation information, when presenting course information related to a predetermined course via a communication line, to a lecture course designated by the student side terminal as the operation side terminal connected to the communication line. Relevant course information can be adopted.

[0009] When presenting course information related to a predetermined course via a communication line such as the Internet, the course information related to the specified course is presented from a student terminal connected to the communication line. In the designation of the course to be attended, the course to be attended is specified in advance by the student, and is specified by receiving it via a communication line.

The course information is transmitted to a student terminal via a communication line. The course information includes predetermined moving image information and slide information related to the moving image information, and is transmitted to the student terminal so as to be cooperatively displayed on the same screen. The moving image information includes dynamic information such as video information of a lecturer, video video information of teaching materials, and live video currently being captured. This moving image information is associated with slide information. In general, a lecturer presents figures, tables, characters, and the like in order to effectively proceed with the lecture. The charts and characters are static contents and can be presented as slide information. Since the slide information is presented in association with the moving image information, it corresponds to the presentation position of the moving image information. Therefore, by presenting the moving image information and the slide information, the course can be effectively advanced.

By the way, students often take memos in time series while attending lectures. Therefore, in the presentation information,
In addition to the video information and the slide information, input information by the student may be added. In this case, the input information may be stored, and the stored input information may be held in association with one of the moving image information and the slide information.

[0012] In the multiple information presentation method, the identification information may be generated corresponding to a change point of the presentation content that changes in time series of the presentation information, and the generated identification information may be transmitted together with the presentation information. .

A plurality of pieces of presentation information, that is, a plurality of pieces of presentation information whose presentation contents change in a time series are presented in a coordinated manner, but each of the presentation contents changes in a time series. By generating the identification information, the identification information can be generated as a feature portion of the presentation information corresponding to a time-series position in the presentation information. For example,
In a moving image, a change point is classified according to a scene or within a certain range of a frame including a characteristic image. In this way, a characteristic image of the moving image can be adopted as the identification information.

In this case, the identification information can extract a part of the presentation information. By extracting a part of the presentation information, the identification information can be generated by a simple process of only extracting an existing image without generating new information.

[0015] The presentation information may include information that changes in a time series and is input by an operator. The operator often makes a note of what is considered to be an idea or important at any time. Such a memo is information that changes over time. Then, the input information by the operator is received via the communication line and presented. It should be noted that the information that changes in a time series need not be real time, but only needs to change in a time series. This allows the operator to simultaneously view information such as character information that changes in time series.

The above multiple information presentation method can be realized by the following multiple information presentation device. Specifically, a multiple information presentation device that presents a plurality of pieces of presentation information whose presentation contents change in a time-series manner through a communication line in cooperation with each other,
The plurality of pieces of presentation information are transmitted to the operating terminal via a communication line so as to be presented in a coordinated manner, and any one of the pieces of presentation information specified by the operator and received via the communication line is transmitted. The identification information corresponding to the chronological position in the presentation information belonging to the specified identification information, and corresponding to the identified identification information, new presentation information is generated so as to be presented in cooperation with each other. Control means for controlling transmission of new presentation information to the operation-side terminal via a communication line is provided.

[0017] The presentation information, when presenting course information related to a predetermined course via a communication line, to a lecture course designated from the student side terminal as the operation side terminal connected to the communication line. Relevant course information can be adopted. In addition, the presentation information may employ dynamic content including moving image information and a plurality of static contents. Further, the presentation information may include information that changes in a time series and is input by the operator.

[0018] The identification information may be generated corresponding to a change point of the presentation content that changes in time series of the presentation information, and the generated identification information may be transmitted together with the presentation information.
Further, the identification information can extract a part of the presentation information.

ce Locator).

First, when the user computer 85 requests the server computer 83 to access the seminar site (course center), the server computer 83 executes the processing routine shown in FIG. Specifically, it is executed in the application interface unit 12 constituting the server computer 83. In step 100 of FIG. 4, as an initial setting,
It generates format information of a screen to be displayed on the user computer 85 and also generates data. Specifically, the information generation unit 1 in the server computer 83
The processing is performed so that various contents (dynamic contents and static contents) of the moving image information and audio information generated in step 4 and various data (tables and the like) stored in the database unit 16 can be referred to. Thereby, the information generation unit 14, the database unit 16, and the index generation unit 18
The information (static content) and the dynamically arranged information (dynamic content) are read out. Then, the data is transmitted to the user computer 85. Accordingly, the user computer 85 presents a list of courses at the course center.

The information may be dynamically generated with reference to various data (tables and the like) stored in the database unit 16. In this case, a search result using attribute information such as an index and an ID as a keyword can be used.

The student refers to or searches for detailed data of courses that can be taken while referring to the course list presented on the user computer 85, and selects a course to be taken. When the course is selected by the student, a request is made from the user computer 85 to the server computer 83, and the server computer 83
In step 102 of FIG. 3, the determination of the course selection is affirmed, and the process proceeds to step 104.

At step 104, the attendance state registered in advance for the attendee ID is read. Here, the attendance state refers to a state in which a student refers to a course that can be attended by its ID, or a state of a course that has been previously taken and interrupted, and the appropriate course is selected for the course selected by the student. This means reading information for determining that a selection has been made, or information for resuming from a halfway state if the course is halfway. Although illustration is omitted, if the course selected by the student cannot be selected,
By transmitting data indicating that selection is not possible to the user computer 85, the student is notified and the present routine is terminated.

Next, in step 106, detailed data (course information) of the available course selected by the student is generated. Then, the data is transmitted to the user computer 85. Thus, the user computer 85 presents the course information of the course to be taken.

FIG. 5 shows an example of a screen displayed on the user computer 85 based on data transmitted from the server computer 83 in the course of taking a course. FIG. 5 is an example of a screen displayed on the user computer 85 when an image of a lecturer and data on a slide of a lecture are output as lecture information. Screen 200

02, a display area 204 of a slide image used for a course, and a display area 206 in which a result (note) of a student who takes the course writes text data such as a memo is displayed.
Contains.

The slide image display area 204 includes a display area 218 for displaying a characteristic image of a moving image as an index image (details will be described later). This display area 218 also has a button function,
As will be described later, it also functions as an instruction area for displaying a moving image at a position represented by the displayed characteristic image. The display area 206 also serves as an input area, and functions as a note in which text data or the like is displayed at the input position.

In the display area 202, buttons 212 to be pressed according to the operation of the instructor's photographed image (moving picture information) are arranged, and in the display area 204, the slide image (slide information) used in the lecture is operated. Buttons 214 to be pressed are arranged. In the display area 206, a button 216 to be pressed when saving text data input by the student is arranged. These buttons are set so that an instruction equivalent to a button press is made by an instruction input of an input device represented by a mouse click or the like. The student presses (eg, clicks with a mouse) one of these buttons,
The corresponding data is transmitted online to the server computer 83.

In the screen 200, buttons 222, 224, 226, and 228 are arranged at the lower right portion. The button 222 is an instruction area to be pressed when shifting to the initial screen of this site, that is, the course selection screen. The button 224 is an instruction area to be pressed when displaying data (notes) input by the student in the display area 206, and the button 226 is a list of data (notes) input so far (list information of the present invention). Is an instruction area to be pressed when displaying. Button 22
Reference numeral 8 denotes an instruction area for implementing the BBS function. B
The BS function, which will be described later in detail, is a place where one or more other participants participate and exchange opinions as a BBS.
By pressing the button 228, the title and content of the opinion are displayed in the display area 206 as a shared area.

The operation buttons 212 include various function buttons as shown in FIG. In the example of FIG. 6, the configuration includes buttons 230 to 237. A button 230 is an instruction area to be pressed when shifting from a scene being reproduced to a previous scene in a moving image of a lecturer composed of a plurality of scenes.
Is an instruction area to be pressed when rewinding the instructor's moving image, and the button 232 is an instruction area to be pressed when playing back the instructor's moving image in reverse. Button 233
Is an instruction area to be pressed when stopping (stopping) the reproduction of the instructor's moving image, and the button 234 is an instruction area to be pressed when temporarily stopping the instructor's moving image. The button 235 is an instruction area to be pressed when the instructor's moving image is reproduced, the button 236 is an instruction area to be pressed when the instructor's moving image is fast-forwarded, and the button 237 is a reproducing area. This is the designated area to be pressed when shifting from the current scene to the next scene.

The operation button 212 includes a button 238
Can be included. Button 238
Is an instruction area to be pressed when synchronizing a moving image of the lecturer with a slide image of the lecture. This button 2
By pressing 38, in synchronization with the playback of the moving image of the instructor,
The slide image of the lecture is displayed.

The operation button 214 is the operation button 2
12, the detailed description is omitted. However, since the slide image is a still image, the buttons 231 and 236 are not particularly necessary in the example of FIG. When the operation button 214 functions in the example of FIG.
Is an instruction area to be pressed when shifting to the first slide image, and the button 232 is an instruction area to be pressed when reproducing the immediately preceding slide image.
The button 233 is an instruction area to be pressed when stopping (stopping) the reproduction of the slide image.
Is an instruction area to be pressed when the reproduction of the slide image is paused, the button 235 is an instruction area to be pressed when the next slide image is reproduced, and the button 237 is This is the designated area to be pressed when shifting to the slide image. The button 238 for synchronizing the instructor's moving image and the lecture slide image may be provided on one of the operation buttons 212 and 214.

Next, in step 108, it is determined whether or not an input has been made for the presented course. in this case,
The determination is made based on whether the button based on the information (FIG. 5) presented to the student is pressed or input is performed on the display area 206. Therefore, in step 108, the determination is repeated until the student makes an input, and the determination is repeated. If the determination in step 108 is affirmative, in step 110, the input by the student is grasped, and when it is not the instruction to end the learning (including the interruption of the learning) (negative in step 112),
After the process corresponding to the input by the student is performed in step 114, the process returns to step 108.

On the other hand, if the instruction is a course end instruction (Yes at step 112), the routine is ended after the end processing is performed at step 114. The termination process of step 116 includes at least storing a state in which attendance has been completed (or interrupted). Thus, the next time this process is executed, another course can be taken or can be taken again. In the case of interruption, it is also possible to resume from the suspended state.

Therefore, the student proceeds with the lecture while referring to the screen 200 described above. Hereinafter, an example of the processing corresponding to the input by the student in Steps 108 to 114 will be described.

For example, when starting a lecture, the button 23
5 is pressed to give an instruction. This is received by the server computer 83, and the photographed image (moving image information) of the instructor
Then, the data of the slide image used for the lecture is transmitted in synchronization with the moving image. Thereby, the student can take the lecture while referring to the image of the lecturer and the slide synchronized with the progress of the lecture.

On the screen 200, text data such as a memo can be entered according to the progress of the lecture (note: display area 206). The entered text data is transmitted from the user computer 85 when the button 216 is pressed, is received by the server computer 83, and is stored in the note table of the database unit 16 corresponding to the student ID. . Thus, the moving image, the slide image, and the note are associated with each other.

During the course of the lecture, when one of the moving image and the slide image is stopped or moved forward or backward due to a desire to look closely, any one of the buttons 212 or 214 is pressed. At this time, the moving image and the slide image are asynchronous, but are adjusted again by pressing the button 238, and the moving image and the slide image are synchronized.

By the way, the student enters text data such as a memo according to the progress of the lecture (note: display area 20).
6) In the case where the student attempts to stop after instructing the stop of the moving image and the slide image, the student must perform the pressing of the button and the entry of the text data in order, and the operation is complicated. Therefore, in the present embodiment, at least the progress of the slide image is stopped when the input of the text data is started by the student. This is because notes such as memos are often generated along with slide images used for lectures, that is, slide images currently referred to. As described above, the progress of the slide image is stopped by one operation of inputting the text data, and the student can write a note while referring to the slide image. This note is associated with the slide image.

The stopped slide image can be synchronized with the moving image by pressing the button 238.
The attendance can be resumed by synchronizing the moving image and the slide image.

When the moving image is paused and the progress of the moving image is easy to stop, such as when playing back a video image, it is easy to resume the moving image. In the case of, the stop itself is difficult. in this case,
If a configuration is adopted in which the stopped moving image is temporarily held and output in the order stored when the moving image is resumed, the information on the time when the moving image is temporarily stopped is delayed, and the student side (user computer 8)
Data can be transmitted to 5).

When the BBS button 228 is pressed on the course screen displayed on the user computer 85 by the data transmitted from the server computer 83, the BBS function is realized. The BBS function is a place for exchanging information between students related to the lecture being taken.
Multiple participants can participate and exchange opinions. Therefore, the student can use this BBS function to present a question or refer to a comment made by another student on a slide image basis. Therefore, it is easy to display or refer to the object of discussion. For this reason, it is possible to improve the degree of understanding for each slide image. In addition, BBS
Instead of the function, a slide image or a question and answer information summarizing a question and answer about the lecture content may be displayed.

When the note list button 226 is pressed on the course screen displayed on the user computer 85, a list function is realized. The list function is a function of displaying a list of input information related to slide images belonging to the lecture being attended together with the slide images. In this list display, input information is sequentially arranged in combination with one slide image.

In the above description, a case has been described in which a result (note) of a student who attends the course writing text data such as a memo is displayed in the display area 206, but the note is shared by a plurality of students. You can also. In this case, a setting for instructing a plurality of students to share the notes may be further added.

Here, an index image, which is a feature image of a moving image, displayed in the slide image display area 204 will be described. First, the concept of generating an index image will be described. FIG. 1 shows a chronological relationship between a moving image to be presented to a student and a slide image, and a chronological relationship between index images (feature images) generated from the moving image.

In general, a moving image 300 is composed of a large number of image frames 302 so that a large number of still images (image frames) are successively presented in time series. Normal,
The moving image 300 has a plurality of scenes (scenes), and the moving image 300 can be classified for each scene (scene). This moving image 300 is associated with slide information 310 including at least one slide image 312. In the example of FIG. 1, an example is shown in which a slide image 312 is associated with a moving image 300 having scenes S1 to Sn for each scene. The association between the moving image and the slide image is made according to the intention of the creator of the course, the intention of the lecturer, or the like. Therefore, the lecture is smoothly understood by presenting the associated slide images to the student in chronological order along with the presentation of the moving image.

The moving image 300 may include a characteristic image. The characteristic image refers to a characteristic image along with a time-series flow of the moving image or a characteristic image in which the characteristics of the subject have appeared, and may be related to a scene of the moving image or may be irrelevant. For example, an image including a specific subject in the background when the lecturer is photographed or a smile image of the lecturer can be used as a feature image as a condition. In the example of FIG. 1, until the feature image according to the above-described arbitrary condition appears irrespective of the scene of the moving image 300, the interval between frames is set to L1 to Lm.
Is shown.

Therefore, the index generator 18 (FIG. 2)
Then, the characteristic image 320 included in the moving image 300 is extracted as image frames K1 to Km. Thus, the image frames K1 to Km become an image database representing a characteristic portion of the moving image 300. This image database is preferably stored in the database unit 16. Note that an image frame represented by a scene change or the like may be used as the characteristic image.
Therefore, the relationship between the moving image 300 and the slide information 310 reflects the intention of the creator, whereas the relationship between the moving image 300 and the characteristic image 320 reflects the characteristics of the moving image itself. become. The index image (feature image) may be generated in advance, or may be generated by designating an image frame.

Therefore, the slide image display area 204
Then, by displaying the characteristic image 320 (index image), the moving image 300, the slide image 312, and the index image 322 are displayed in a time-series manner. Thus, along with the progress of the lecture, for example, a moving image of the lecturer is displayed in the display area 202, a slide image intended by the lecturer is displayed in the display area 204, and a characteristic image included in the moving image is displayed in the display area 218. The lecture contents can be presented in a multifaceted manner as the lecture progresses.

By pressing the display area 218, the student can instruct to display a moving image at a position represented by the displayed characteristic image. The display area 2
The characteristic image displayed on 18 can be moved forward and backward by pressing the operation button 214. This instruction is received by the server computer 83, the inter-frame of the corresponding moving image is specified, and the image of the instructor (moving image information) and the data of the slide image used for the lecture are transmitted in synchronization with the moving image. As a result, the student can view the range of the moving image specified by the feature image.

Next, the timing of extracting the index image and the index image will be described. FIG. 7 shows a flow of a moving image, a slide image, and a text input for a lecture which is the basis of the following description. In the moving image, scenes S1, S2, and S3 are started at timings t1, t4, and t5, and the slide image is a slide image P1,
P2 and P3 are presented at times t2, t6 and t8, and the text input of the student is performed by texts T1, T2 and T8.
3 is input at the timings of times t3, t7, and t9.

These timings (time t1 to t9)
Corresponds to an event (change point) in the lecture being taken. Further, these timings can be detected by detecting the instruction of the student or reading the data stored as data. An event can be considered a characteristic point in time for a lecture. Therefore, a first process for generating an index for a moving image will be described. The first process is a process of generating an index based on an event generated for a moving image and a slide image.

As shown in FIG. 8, the moving image and the slide image are time-sequentially represented by time t1, t2, t4, t5, t6,
At t8, an event has occurred. Therefore, the index generation unit 18 (FIG. 2) extracts an image corresponding to each event and sets it as an index image. By referring to the extracted index image, it is possible to view that the event has occurred, and it becomes an image database representing the characteristic portion of the moving image. In the above description, the case where the index image is extracted from one of the moving image and the slide image has been described. However, the present invention is not limited to the image, and may be any corresponding information. For example, the IP address or UR of another computer corresponding to the file name or image data
L may be used.

Next, a second process for generating an index for a moving image will be described. The second process is a process of generating an index using all of the images corresponding to the event generated for the moving image and the slide image.

As shown in FIG. 9, the moving image and the slide image are chronologically represented by time t1, t2, t4, t5, t6,
At t8, an event has occurred. This is the same as the event in FIG. 8, but in the second processing, both the moving image and the slide image corresponding to each event are extracted as images corresponding to each event in the index generation unit 18 (FIG. 2). Let it be an index image. In the example of FIG.
Images directly attributable to each event are represented by solid lines, and images to which they belong are represented by dotted lines. Since both images are extracted as described above, the student can select which image to view.

Next, a third process for generating an index for a moving image will be described. The third process is a process of generating an index using all pieces of information corresponding to an event generated for a moving image, a slide image, and a text input.

As shown in FIG. 10, in a moving image, a slide image, and a text input, events occur in time series at times t1 to t9. In the third process, the index generation unit 18 (FIG. 2) converts all of the moving image, slide image, and text information corresponding to each event into an index.
The information is extracted as information corresponding to each event and used as index information. In the example of FIG. 10, information directly attributable to each event is represented by a solid line, and information to which the event belongs is represented by a dotted line.
Since all the information has been extracted in this way, the student can selectively view and instruct the information.

In the above, in the course of taking the course,
As an example of a screen displayed on the user computer 85 based on the data transmitted from the server computer 83, a display area 218 in the slide image display area 204 is displayed.
In the above, the case where the characteristic image of the moving image is displayed as the index image has been described (the screen 200 in FIG. 5), but the present invention is not limited to the index image.
As shown in FIG. 11, a keyword representing an event or index information such as a time at which the event occurred may be displayed.

In the above description, the user computer 8
As an example of the screen displayed on the screen 5, the case where the display area 218 is provided in the display area 204 of the slide image to display the index image and the index information has been described, but the present invention does not use the display position. Absent. For example, FIG.
As shown in 2, photographed image (moving image) of the lecturer who gives the lecture
An area 217 may be provided in the display area 202 to display index information such as a keyword indicating a display event and a time at which the event occurred.
