Since the computer has a general and general hardware configuration, detailed description thereof is omitted.
[0025]
FIG. 2 is a functional block diagram showing information exchange by the computer having the above-described configuration. This system can be classified into server computer 83 and user computer 85. These computers are not limited to a single computer, and a plurality of computers may be connected via a network and function as a system.
[0026]
The server computer 83 includes an application interface unit 12, an information generation unit 14, and a database unit 16. Each of these units may be configured by a computer and connected so as to be able to exchange information. The application interface unit 12 is a functional unit that mainly performs information exchange with other computers and various processes. The information generation unit 14 is a functional unit that generates real-time information mainly by shooting to generate moving image information or recording to generate audio information. The database unit 16 is a functional unit that refers to and extracts various tables and data.
[0027]
As an example of what is included in the database unit 16, a student master that stores data such as a student ID that can be attended, a lecturer master that stores data such as a lecturer ID in charge of a course, and data of a lecture ID that can be held There is a course master in which is stored. Further, in relation to each of the held lectures, there are a moving image table storing moving image information, a slide table storing slide information, and a note table storing input information input by students. Furthermore, there is a BBS table that stores remark information and question information related to each of the held courses or between a plurality of courses.
[0028]
The application interface unit 12 includes a delay synchronization unit 20. As shown in FIG. 3, the delay synchronization unit 20 included in the application interface unit 12 includes a holding controller 22, an interface unit 24, and a buffer unit 26.

In addition, the information generation unit 14 and the database unit 16 are connected to the buffer unit 26 so as to be able to exchange information.
[0029]
Next, the operation of this embodiment will be described. In the present embodiment, a case will be described in which the server computer 83 functions as a WWW (World Wide Web) server and the user computer 85 functions as a WWW client. In this case, a network-accessible program (a so-called WWW browser) is installed in the user computer 85, and the server computer 83 can be accessed via the network 88 by starting the WWW browser. The access position (data constituted by the position of the server computer 83 to be accessed and the position of information in the server computer 83) is designated by a so-called URL (Uniform Resource Locator).
[0030]
First, when an access request is made from the user computer 85 to the server site 83 to 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, format information of a screen to be displayed on the user computer 85 is generated and data is generated as an initial setting. Specifically, moving image information and audio information generated by the information generation unit 14 in the server computer 83, various contents (dynamic content and static content) of various data (tables and the like) stored in the database unit 16 ) Is made available for reference. Thereby, information (static content) statically arranged in the information generation unit 14 and the database unit 16 and information (dynamic content) dynamically arranged are read out. Then, data is transmitted to the user computer 85. Accordingly, the user computer 85 presents a list of courses at the course center.
[0031]
The information may be dynamically generated while referring to various data (tables and the like) stored in the database unit 16. In this case, a result of searching using attribute information such as ID as a keyword can be used.
[0032]
The student refers to the detailed data of the lectures that can be taken while referring to the course list presented on the user computer 85, and selects the 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. In the server computer 83, the judgment of course selection is affirmed in step 102 of FIG. .
[0033]
In step 104, the attendance state registered in advance for the student ID is read. Here, the attendance state means a state in which a student refers to a lecture that can be attended by the ID, or a state of a course that has been interrupted by a previous attendance. This means reading information for determining that the selection has been made, or reading information for resuming from the halfway state when the course is in the middle. Although not shown in the figure, when the course selected by the student is not selectable, the data indicating that selection is not possible is transmitted to the user computer 85 to notify the student and the present routine is terminated. To do.
[0034]
Next, in step 106, detailed data (course information) of courses that can be taken by the student is generated. Then, data is transmitted to the user computer 85. As a result, the user computer 85 presents the course information of the attended course.
[0035]
FIG. 5 shows an example of a screen displayed on the user computer 85 by 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 the lecturer image and the data related to the lecture slide are output as the lecture information. The screen 200 displays a photographed image (moving image) display area 202 of a lecturer who conducts a course, a slide image display area 204 used for the course, and a result of text data such as a memo written by a student attending the course (notes). ) Is displayed. The display area 206 also serves as an input area, and functions as a note in which data is displayed at a position where text data or the like is input.
[0036]
In the display area 202, a button 212 to be pressed according to the operation of the photographed image (moving picture information) of the instructor is arranged, and the display area 204 is pressed according to the operation of the slide image (slide information) used in the lecture. A power button 214 is arranged. In the display area 206, a button 216 to be pressed when storing the text data input by the student is arranged. These buttons are set so that an instruction corresponding to pressing of the button is given by an instruction input of an input device represented by a mouse click or the like. The student presses one of these buttons (for example, clicks with a mouse) to transmit the corresponding data online to the server computer 83.
[0037]
The screen 200 has buttons 222, 224, 226, and 228 arranged at the lower right part thereof. 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. A button 224 is an instruction area to be pressed when displaying data (notes) input by the student in the display area 206, and a button 226 is a list of data (notes) input so far (list information of the present invention). This is an indication area to be pressed when displaying. The button 228 is an instruction area for realizing the BBS function. Details of the BBS function will be described later. As a BBS, one or a plurality of other students participate and exchange opinions. When the button 228 is pressed, the title and content of the opinion are displayed as a shared area. It is displayed in 206.
[0038]
The operation button 212 includes various function buttons as shown in FIG. In the example of FIG. 6, the buttons 230 to 237 are included. The button 230 is an instruction area to be pressed when moving from the scene being reproduced to the previous scene of the moving image of the instructor composed of a plurality of scenes, and the button 231 winds the moving image of the instructor. An instruction area to be pressed when returning, and a button 232 is an instruction area to be pressed when reversely reproducing a lecturer's moving image. The button 233 is an instruction area to be pressed when stopping (stopping) 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 reproducing the instructor's moving image, the button 236 is an instruction area to be pressed when fast-forwarding the instructor's moving image, and the button 237 is being reproduced. This is an instruction area to be pressed when moving from one scene to the next.
[0039]
This operation button 212 can be configured to include a button 238. The button 238 is an instruction area to be pressed when synchronizing the lecturer's moving image and the lecture slide image. By pressing the button 238, a slide image of the lecture is displayed in synchronization with the reproduction of the moving image of the lecturer.
[0040]
Since the operation button 214 has substantially the same configuration as the operation button 212, detailed description thereof 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. It is. When the operation button 214 is caused to function in the example of FIG. 6, the button 230 is an instruction area to be pressed when moving to the first slide image, and the button 232 is used when reproducing the previous slide image. This is an instruction area to be pressed. The button 233 is an instruction area to be pressed when the slide image reproduction is stopped (stopped), and the button 234 is an instruction area to be pressed when the slide image reproduction is temporarily stopped. Is an instruction area to be pressed when reproducing the next slide image, and a button 237 is an instruction area to be pressed when moving to the last slide image. Note that the button 238 for synchronizing the above-described lecturer moving image and lecture slide image may be provided on either one of the operation buttons 212 and 214.
[0041]
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 side is pressed or the display area 206 is input. Accordingly, in step 108, the determination is repeated until input by the student is made, and the determination is repeated. If the determination in step 108 is affirmative, in step 110, the input by the student is grasped, and if it is not the instruction to end the learning (including interruption of the learning) (No in step 112), the processing corresponding to the input by the student is performed in step 114. Then, the process returns to step 108.
[0042]
On the other hand, when the instruction is an instruction to end attendance (Yes at step 112), the routine ends after the end processing is performed at step 114. The termination process in step 116 includes at least saving the state in which the course has been completed (or interrupted). Thereby, when this process is executed next time, another course can be taken or can be taken again. Moreover, when interrupted, it can also restart from the interrupted state.
[0043]
Accordingly, the student advances the lecture while referring to the screen 200 described above. Hereinafter, an example of processing corresponding to input by the student in Step 108 to Step 114 will be described.
[0044]
For example, when starting a lecture, an instruction is given by pressing the button 235. This is received by the server computer 83 and the photographed image (moving image information) of the lecturer and the slide image data used in the lecture are 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.
[0045]
On the screen 200, text data such as a memo can be written in accordance with 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, and is received by the server computer 83 and stored in the notebook table of the database unit 16 corresponding to the student ID. . Thereby, the moving image, the slide image, and the note are associated with each other.
[0046]
During the course of a lecture, when either a moving image or a slide image is to be stopped or advanced or retracted due to a desire to take a close look, any of the buttons 212 or 214 is pressed. At this time, the moving image and the slide image become asynchronous, but are readjusted by pressing the button 238, and the moving image and the slide image are synchronized.
[0047]
By the way, when a student enters text data such as a memo in accordance with the progress of a lecture (note: display area 206), if the student tries to do so after instructing to stop the moving image and the slide image, The pressing and text data entry must be performed in order, and the operation is complicated. Therefore, in the present embodiment, at least when the student starts inputting text data, the progress of the slide image is stopped. This is because a note such as a memo is often generated accompanying a slide image used in a lecture, that is, a slide image currently referred to. Thus, the progress of the slide image is stopped by one operation of inputting the text data, and the student can write the note while referring to the slide image. This note is associated with the slide image.
[0048]
The stopped slide image can be synchronized with the moving image by pressing the button 238, and the attendance can be resumed by synchronizing the moving image and the slide image.
[0049]
Also, when it is easy to stop the progress of the moving image, such as playing a video image, when the moving image is paused, it is easy to resume, but in the case of simultaneous screening or live video It is difficult to stop itself. In the present embodiment, the stopped moving image can be temporarily held in the delay synchronization unit 20. That is, usually, a moving image or the like passes through the buffer unit 26 and is transmitted to the student side (user computer 85) via the interface unit 24.
[0050]
Here, when the student gives an instruction to suspend, the interface unit 24 notifies the holding controller 22 to that effect. The holding controller 22 controls the buffer unit 26 to start holding data. Thus, the stopped moving image is temporarily held in the buffer unit 26. When the student gives a resumption instruction, the interface unit 24 notifies the holding controller 22 to that effect. The holding controller 22 controls the buffer unit 26 so as to output the held data in the order in which the held data is held in a so-called first-in-first-out manner. As a result, the moving images temporarily held in the buffer unit 26 during the stop are output in the time series in which they are held. Thereby, data transmission is restarted to the student side (user computer 85) via the interface unit 24, and it can be restarted from the interrupted state.
[0051]
FIG. 7 shows an example of a screen 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. When the button 228 is pressed, the BBS function is realized. The BBS function is a place for exchanging information between students related to the lectures they are taking, and multiple students can participate and exchange opinions.
[0052]
FIG. 7 shows an example in which the title and contents of the opinion are displayed in the display area 206 as the shared area 242 in the display area 206. A button 244 to be pressed when the student speaks on the slide image is arranged at the upper part of the shared area 242, and the information in the shared area 242, that is, the comment is updated to new information next to the button 244. A button 246 to be sometimes pressed is arranged. Below these buttons 244 and 246, a display area 245 in which a comment related to the slide image displayed in the display area 204 is presented is arranged.
[0053]
In the display area 245, the title 248 of the message is displayed for each item, and an icon corresponding to the content of the item is displayed adjacent to the item (in the example of FIG. 7, the case where the content is a sentence) is displayed. Next to that, a mark 250 representing the addition of a comment from the student is displayed in the comment item. By pressing this mark 250, a comment for the target utterance is expanded and displayed. In the example of FIG. 7, the shared area 242 is displayed instead of the display area 206. However, the display area 206 and the shared area 242 corresponding to the above-described note may be displayed on the same screen. Good.
[0054]
Accordingly, the student can use this BBS function to present a question in units of slide images and to refer to comments made by other students. Therefore, it becomes easy to display or refer to the object of discussion. For this reason, it is possible to improve the degree of understanding in units of slide images.
[0055]
In addition, instead of the BBS function, questions regarding slide images and lecture contents and answers to questions may be displayed.
[0056]
FIG. 8 shows a screen example when the note list button 226 is pressed on the course screen displayed on the user computer 85 by the data transmitted from the server computer 83. When the button 226 is pressed, the list function is realized. The list function is a function for displaying a list of input information related to slide images belonging to the lectures being taken together with the slide images. The screen 260 includes a display area 278 for displaying a list and a display area 279 for displaying environment setting information for display.
[0057]
In the display area 278, a course name display area 262 is provided above. Below that, a slide image number display area 264, a slide image display area 266, and an input information display area 268 for the slide image are arranged in combination for one slide image.
[0058]
The display area 279 includes a display area 270 of the type of environment setting information to be displayed, a display area 272 for selecting display settings below it, a button 274 for instructing the setting area 278 to reflect the setting, and a setting. A button 276 for resetting is provided. In the example of FIG. 8, a title indicating that the display format of the note is set is displayed as the type of the environment setting information, and whether to display each of the slide display, the creation date, and the update date is displayed as a display setting selection. Has been. This selection of availability can be realized by arranging check boxes used in the user interface of the computer. The student selects the check box (for example, clicks the slide display item with the mouse), the corresponding part is highlighted and can be designated.
[0059]
When the student presses the button 274, the selection or non-selection of the check box is scanned, and the state, that is, the state of the check box is transmitted as data from the user computer 85 to the server computer 83. As a result, the server computer 83 generates list information data in accordance with the environment setting information set by the student and transmits it to the user computer 85. As a result, the list information according to the environment setting information is displayed on the user computer 85. Accordingly, the student can view the text data input for each slide image in relation to the slide image.
[0060]
In the above description, a case has been described in which a result (note) in which text data such as a memo is entered by a student attending a course is displayed in the display area 206, but the notebook can be shared by a plurality of students. . In this case, a setting for instructing to share the note among a plurality of students may be further added.
[0061]
FIG. 9 shows an example of a screen displayed on the user computer 85 for enabling a notebook to be shared by a plurality of students. The screen 280 is substantially the same as the screen 200 of FIG. 5, and a different part instructs the display area 206 to share the result (note) in which the students who take the course enter text data such as a memo. The point is that the display area 207 is added with a button 217 to be sometimes pressed.
[0062]
The button 217 is set so that an instruction corresponding to pressing of the button is given by an instruction input of an input device represented by a mouse click or the like. The student presses the button 217 (for example, clicks with the mouse), thereby transmitting an instruction to share the currently input data to the server computer 83 online. As a result, a notebook as input data can be shared by a plurality of students.
[0063]
The students to be shared can be set separately on the setting screen. FIG. 10 shows an example of the setting screen. The setting screen 282 includes a sharing target student display area 284 and a setting display area 286 in which a button for setting a sharing level is arranged for each sharing target student. In the example of FIG. 10, the students who are to be shared are the person himself / herself, a predetermined specific user, users included in a predetermined disclosure list, all the students, and a course administrator. A browse button 286A, an additional write button 286B, an erase button 286C, and a change button 286D are provided for each target person as buttons for setting a sharing level. The browse button 286A is a setting button that enables only browsing of notes, the append button 286B is a setting button that allows additional writing to notes, and the delete button 286C deletes written data of notes. The change button 286D is a setting button that allows the access item itself to be changed. By pressing these buttons 286A to 286D, it is possible to make detailed settings for sharing a note for each subject.
[0064]
In this way, by sharing the input information of the students, it is possible to deepen the sharing of knowledge among the students even between remote locations. In addition, since the level can be set for sharing, the sharing can be changed for each input information, and fine settings can be made for the input information.
[0065]
This setting information is preferably interpolated in combination with personal note data in the system. In addition, for access from other students (users), for example, a list of notes for any slide image, etc. is displayed, and the name of the student who wrote the note is displayed and given to that student It is preferable that the notes can be opened (referenced or updated) according to the sharing level.
[0066]
By the way, when taking a course at a remote location via a communication line, there is a case where it is desired to temporarily interrupt the course due to an emergency or the like during the course. In this case, it is preferable that the interrupted lecture is restarted easily and efficiently. Therefore, in the present embodiment, a resume function for resuming a lecture that is temporarily interrupted can be added. In the resume function, when an instruction to interrupt the course is given by the student, the system stores the playback position of the moving image, the slide image being displayed, and the BBS state in association with each other, and a playback request is instructed by the student. At the time, the stored state is reproduced so that the lecture can be resumed, that is, the course can be started immediately.
[0067]
In the case of saving the BBS state, other students may write while the student is interrupting the lecture. Therefore, while the student interrupts the course, input information such as text added by other students is displayed with a difference when resumed. For example, the character color is changed, the font is changed, or the character is decorated. In addition, the student may be notified visually that the added input information exists. Furthermore, since the instructor's writing is assumed to be an important content, it is preferable to highlight such as bolding or underlining. Furthermore, the interrupted time may be automatically entered. These resumed states can be recorded in the server computer 83.
[0068]
FIG. 11 shows an example of a screen displayed on the user computer 85 when the lecture is interrupted and resumed while taking a lecture while performing BBS (presentation of online information). Screen 290 includes an online display area 292 of the BBS. In this online display area, input information is displayed in time series. First, when the student A writes the input information 293 when the lecture is interrupted, the system automatically writes the interrupted student and the interrupted time as the input information 294. While the student A is interrupting the course, the input information 295 such as text added by the other student B is displayed differently from the input information 293 (for example, the color is changed) (resume). And display them with a difference). The input information 296 written by the lecturer is underlined and highlighted so as to attract attention. When the student A instructs to resume, the time when the student A resumes is automatically entered as input information 297 by the system. In this way, even if an instruction to interrupt the course is given by the resume function by the resume function, the interruption state is stored in the system, and when the reproduction request is instructed, each stored state is reproduced or interrupted. Since it makes a difference in the information inside, it is possible to immediately resume the lecture, that is, to take the course, and to grasp the information change during the interruption.

The record of the state at the time of resume can include device information of the user computer 85 when the lecture is interrupted. By recording the resume state including the device information of the user computer 85 in the server computer 83, when a suspended lecture is resumed, even a different user computer 85 can be easily reproduced. As an example, there are specifications of the main body of a computer and a display device. In this case, when it is difficult for the different user computer 85 to display information equivalent to the computer before the interruption, it is preferable to display the information in accordance with the computer specifications after the resume. For example, when the number of colors decreases, a corresponding process of selecting a color as appropriate, or when the number of image pixels decreases, appropriately selecting the number of pixels is added. This correspondence processing can be considered to process data using the attendance environment that is currently used, and to pull out separately prepared data from the course side.
