DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an information display program, an information display method, and an information display device according to the present invention will be described in detail below with reference to the drawings.

(Embodiment 1)
FIG. 1 is an explanatory diagram showing an example of the information display method according to the first embodiment. In FIG. 1, an information display device 101 is a computer capable of displaying moving images. In a moving image, the image changes depending on the elapsed time. The moving image is, for example, a class video such as an online class. Online classes are classes conducted via the Internet. Further, the moving image may be an introduction video or a how-to video of a product or service.

University classes often use a lot of technical terminology and the content is sophisticated, so not all students in attendance understand everything. Additionally, during face-to-face classes, some students were hesitant to ask questions out loud in the large classrooms even if they had questions during class.

On the other hand, in the case of online classes, for example, when a student has a question during class, a method can be considered in which the student tags the student and directly informs the teacher of the question. The tagging operation is an operation of attaching a tag to an image included in a moving image. By checking the parts of the video that students have tagged, teachers can understand the parts that students have questions about.

However, with this method, the action is between the teacher and each student, so it is difficult for students to know which areas other students are interested in or have questions about. For example, unless a student is able to understand the parts that other students have tagged, he or she will not be able to know the parts that other students have questions about and use them for his or her own learning.

Therefore, in Embodiment 1, an information display method for visualizing a portion of a moving image that has been selected by a viewer will be described.

In the example of FIG. 1, the information display device 101 displays a moving image 110 on the display screen 102. At this time, if there is an image that has been selected by one or more viewers of the video 110 among the multiple images included in the video 110, the information display device 101 displays a bar (seek bar) 120 and a bar (seek bar) 120. The icon associated with the position corresponding to the image for which the selection in step 120 has been accepted is displayed.

The moving image 110 is, for example, a lesson moving image. The viewers are, for example, university students. The bar 120 is a bar that can specify the current playback location from the start to the end of the moving image 110. The image for which the selection has been accepted is, for example, an image on which a tagging operation has been performed by the viewer. For example, the viewer tags parts of the video 110 that he or she does not understand or parts that he or she would like to ask questions about later.

The icon is, for example, a figure or symbol indicating the existence of the image for which selection has been accepted. The shape and size of the icon can be set arbitrarily. Here, icons 131, 132, and 133 are displayed on the bar 120 above positions 121, 122, and 123 corresponding to the images for which selection has been accepted.

Note that the icons 131, 132, and 133 may be displayed at the bottom of the positions 121, 122, and 123, or may be displayed at the positions 121, 122, and 123. Further, the display screen 102 may be included in the information display device 101 or may be included in another computer different from the information display device 101. When the other computer has the display screen 102, the information display device 101 controls the other computer to display the moving image 110 on the display screen 102, for example.

In this way, according to the information display device 101 according to the first embodiment, it is possible to visualize the portion of the moving image for which the selection has been received from the viewer. Thereby, the information display device 101 can display in an easy-to-understand manner which parts other viewers are interested in or have questions about, allowing them to efficiently check the content of the moving image.

In the example of FIG. 1, the user (student) can, for example, operate the slider 140 on the display screen 102 to check the images of the portions of the moving image 110 that correspond to the icons 131, 132, and 133. The slider 140 is an operation component for changing the playback location. As a result, the user (student) can, for example, learn about parts that other students have doubts about, notice things that he or she has overlooked, and deepen their understanding of the lesson.

(Embodiment 2)
Next, the information display device 101 according to the second embodiment will be explained. Note that descriptions of the same parts as those described in Embodiment 1 will be omitted.

First, a system configuration example of an information processing system 200 including the information display device 101 according to the second embodiment will be described. The information processing system 200 is applied, for example, to a service that supports learning using online classes in educational institutions and companies.

FIG. 2 is an explanatory diagram showing an example of the system configuration of the information processing system 200. In FIG. 2, an information processing system 200 includes an information display device 101 and a plurality of client terminals 201. In the information processing system 200, the information display device 101 and the client terminal 201 are connected via a wired or wireless network 210. The network 210 is, for example, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), or the like.

Here, the information display device 101 has a tagging history DB (Database) 220 and displays moving images. The moving image is, for example, a lesson video of an online class. The tagging history DB 220 records a log (tagging history) regarding tagging operations performed during playback of a moving image. The storage contents of the tagging history DB 220 will be described later using FIG. 4. Information display device 101 is, for example, a server.

Client terminal 201 is a computer used by a user. The users are, for example, teachers and students who give online classes. Client terminal 201 has a display dv1 and an input device dv2. The display dv1 is a display device that displays data such as a cursor, icons, or toolbox, as well as documents, images, and functional information. The display dv1 is, for example, a liquid crystal display or an organic EL (electroluminescence) display.

The input device dv2 has keys for inputting characters, numbers, various instructions, etc., and inputs data. The input device dv2 may be a keyboard, a mouse, or the like, or may be a touch panel type input pad, a numeric keypad, or the like. Although not shown, the client terminal 201 includes a camera, a speaker, a microphone, and the like.

A camera is a photographing device that photographs images (still images or moving images) and outputs image data. For example, the camera is installed at a position where it can photograph the user using the client terminal 201. The speaker converts the electrical signal into sound and outputs the sound. A microphone receives sound and converts it into an electrical signal. The client terminal 201 is, for example, a PC (Personal Computer), a tablet PC, a smartphone, or the like.

In the information processing system 200, a teacher (for example, a university professor) can use the client terminal 201 to conduct online classes. Furthermore, students can use the client terminal 201 to participate in online classes and view class videos after the online class ends.

Note that although the information display device 101 is provided separately from the client terminal 201 here, the present invention is not limited to this. For example, the information display device 101 may be realized by each client terminal 201.

(Example of hardware configuration of information display device 101)
Next, an example of the hardware configuration of the information display device 101 will be described.

FIG. 3 is a block diagram showing an example of the hardware configuration of the information display device 101. In FIG. 3, the information display device 101 includes a CPU (Central Processing Unit) 301, a memory 302, a disk drive 303, a disk 304, a communication I/F (Interface) 305, and a portable recording medium I/F 306. , and a portable recording medium 307. Further, each component is connected to each other by a bus 300.

Here, the CPU 301 is in charge of overall control of the information display device 101. CPU 301 may have multiple cores. The memory 302 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), a flash ROM, and the like. Specifically, for example, the flash ROM stores an OS program, the ROM stores an application program, and the RAM is used as a work area for the CPU 301. The program stored in the memory 302 is loaded into the CPU 301 and causes the CPU 301 to execute the coded processing.

The disk drive 303 controls reading/writing of data to/from the disk 304 under the control of the CPU 301 . The disk 304 stores data written under the control of the disk drive 303. Examples of the disk 304 include a magnetic disk and an optical disk.

The communication I/F 305 is connected to a network 210 through a communication line, and is connected to an external computer (for example, the client terminal 201 shown in FIG. 2) via the network 210. The communication I/F 305 serves as an interface between the network 210 and the inside of the device, and controls data input/output from an external computer. For example, a modem or a LAN adapter can be used as the communication I/F 305.

The portable recording medium I/F 306 controls reading/writing of data to/from the portable recording medium 307 under the control of the CPU 301 . The portable recording medium 307 stores data written under the control of the portable recording medium I/F 306. Examples of the portable recording medium 307 include a CD (Compact Disc)-ROM, a DVD (Digital Versatile Disk), and a USB (Universal Serial Bus) memory.

Note that the information display device 101 may include, for example, an input device, a display, etc. in addition to the above-described components. Further, the client terminal 201 shown in FIG. 2 can also be realized with the same hardware configuration as the information display device 101. However, in addition to the components described above, the client terminal 201 includes, for example, a display dv1 (see FIG. 2), an input device dv2 (see FIG. 2), a camera, a speaker, a microphone, and the like.

(Memory contents of tagging history DB 220)
Next, the storage contents of the tagging history DB 220 included in the information display device 101 will be explained using FIG. 4. The tagging history DB 220 is realized by a storage device such as a memory 302 and a disk 304, for example. Here, it is assumed that the video is a "class video of an online university class" and the viewers of the video are "university students."

FIG. 4 is an explanatory diagram showing an example of the storage contents of the tagging history DB 220. In FIG. 4, the tagging history DB 220 has fields for lecture ID, student number, tag, and elapsed time, and by setting information in each field, tagging history information (for example, tagging history information 400-1 , 400-2) is stored as a record.

Here, the lecture ID is an identifier that uniquely identifies a moving image. The student number is an identifier that uniquely identifies the viewer. The tag indicates a tag added by a viewer. For example, there are five types of tags, tags T1 to T5. Tag T1 is a tag indicating "I don't know." Tag T2 is a tag indicating "Ask a question later."

Tag T3 is a tag indicating "important point". Tag T4 is a tag indicating "memo". Tag T5 is a tag indicating "I want to discuss." The elapsed time is the elapsed time (hours: minutes: seconds) since the start of playback of the moving image, and indicates the timing at which the video was tagged. However, the elapsed time is the elapsed time when the video is played back at 1x speed from the start of the video.

For example, the tagging history information 400-1 indicates that the position of the tag T4 attached by the viewer S1 in the moving image K1 is at the timing when 3 minutes and 14 seconds have passed from the start of the moving image K1. Note that the moving image K1 is a moving image with the lecture ID "K1". Viewer S1 is a viewer with student number "S1".

(Example of tagging operation screen)
Next, an example of a tagging operation screen displayed on the display dv1 of the teacher's or student's client terminal 201 when conducting an online class will be described.

FIG. 5 is an explanatory diagram showing an example of the tagging operation screen, and is an example of the operation screen displayed on the student's client device 201. In FIG. 5, a tagging operation screen 500 is an example of an operation screen displayed when conducting an online class. The tagging operation screen 500 displays a moving image K3 and face images f1 to f5.

The moving image K3 is an example of a lesson moving image in which the image changes depending on the elapsed time. The face image f1 is a face image of a teacher who gives an online class. The facial images f2 to f5 are facial images of students participating in the online class. For example, the student's face image changes randomly.

On the tagging operation screen 500, the user (student) can, for example, input a tag using the input device dv2 (see FIG. 2) by moving the cursor cr and selecting one of the buttons b1 to b5. You can perform attach operations. Buttons b1 to b5 correspond to tags T1 to T5 described in FIG. 4, respectively.

Which of the buttons b1 to b5 is selected depends on, for example, the user's (student's) understanding and impression of the content of the video image K3.

For example, if a user (student) has a question while viewing an image included in video K3 and selects button b1, he or she can add tag T1 to the currently displayed image in video K3. can. Further, when the user (student) wishes to ask a question while viewing the moving image K3, by selecting the button b2, the user (student) can attach the tag T2 to the currently displayed image of the moving image K3.

Moreover, when the user (student) selects the button b3 when he/she thinks that there is an important part while viewing the moving image K3, the user (student) can attach the tag T3 to the currently displayed image of the moving image K3. Further, when the user (student) wishes to take notes while viewing the moving image K3, by selecting the button b4, the user (student) can attach a tag T4 to the currently displayed image of the moving image K3.

Further, when the user (student) desires to have a discussion while viewing the moving image K3, by selecting the button b5, the user (student) can attach a tag T5 to the currently displayed image of the moving image K3. Note that a seek bar indicating the elapsed time since the start of the online class may be displayed on the tagging operation screen 500.

(Functional configuration example of information display device 101)
FIG. 6 is a block diagram showing an example of the functional configuration of the information display device 101. As shown in FIG. In FIG. 6, the information display device 101 includes a first reception section 601, a recording section 602, a second reception section 603, a display control section 604, and a storage section 610. The first reception unit 601 to display control unit 604 are functions of the control unit 600, and specifically, they are stored in a storage device such as the memory 302, disk 304, or portable recording medium 307 shown in FIG. The function is realized by causing the CPU 301 to execute the program or by the communication I/F 305. The processing results of each functional unit are stored in a storage device such as the memory 302 or the disk 304, for example. Furthermore, the storage unit 610 is realized by a storage device such as the memory 302 and the disk 304, for example. Specifically, for example, the storage unit 610 stores the tagging history DB 220 shown in FIG. 4.

The first receiving unit 601 receives a selection of any one of the plurality of images included in the moving image from a viewer of the moving image. Selection of images is, for example, a tagging operation. Furthermore, selecting an image may be an operation of attaching a tag selected from a plurality of tags. A plurality of tags can be set arbitrarily, and each tag has a different attribute. Each tag represents, for example, the viewer's understanding, impression, evaluation, etc. of the content of the moving image. The plurality of tags are, for example, tags T1 to T5 described in FIG. 4.

Image selection is performed, for example, on a tagging operation screen 500 as shown in FIG. Specifically, for example, during playback of a class video of an online class (for example, video K3 shown in FIG. 5), the first reception unit 601 receives multiple messages included in the class video from the student's client terminal 201. The selection of one of the images is accepted.

When receiving an image selection, the recording unit 602 records operation history information regarding the selection in the storage unit 610. The operation history information includes information that allows identification of the image for which selection has been accepted among the plurality of images included in the moving image. For example, assume that a tagging operation for any one of a plurality of images included in a lesson video is received from a student's client terminal 201.

The tagging operation is, for example, an operation of attaching a tag selected from tags T1 to T5 (see FIGS. 4 and 5). In this case, the recording unit 602 may record, for example, tagging history information regarding the tagging operation in the tagging history DB 220 as shown in FIG. 4 . Tagging history information is an example of operation history information.

The tagging history information includes, for example, a lecture ID, student number, tag, and elapsed time as shown in FIG. 4. The lecture ID uniquely identifies the moving image. The student number uniquely identifies the viewer. The viewer is a user (student) of the client terminal 201. The tag is a tag added by a viewer. The elapsed time corresponds to information representing the time point at which an image is reproduced, and is information that allows identification of a tagged image (location) in a moving image.

The second receiving unit 603 receives an instruction to display the selection status of images included in a moving image. Specifically, for example, the second reception unit 603 receives an instruction to display the tagging status of a moving image from the teacher's or student's client terminal 201. The tagging status display instruction includes, for example, a lecture ID.

When displaying a moving image, if there is an image that has been selected by one or more viewers of the moving image among a plurality of images included in the moving image, the display control unit 604 displays the seek bar and the seek bar. The icon associated with the position corresponding to the selected image is displayed. The seek bar is a bar that allows you to specify the current playback location from the start to the end of the video.

The icon is, for example, a figure or symbol indicating the existence of the image for which selection has been accepted. The shape and size of the icon can be set arbitrarily. Further, the display position of the icon can be arbitrarily set, and may be, for example, at the top or bottom of the corresponding position on the seek bar.

The corresponding position is a position on the seek bar that corresponds to the image for which the selection has been accepted. The corresponding position is, for example, a position on the seek bar that corresponds to a time period including the image for which the selection has been accepted, among a plurality of time periods divided by fixed time intervals from the start to the end of the moving image.

Specifically, for example, the display control unit 604 refers to the tagging history DB 220 in response to a video tagging status display instruction, and selects one or more of the multiple images included in the video. It is determined whether or not there is an image that has been selected by a viewer. Then, when displaying a moving image, if the display control unit 604 determines that there is an image for which the selection has been accepted, it displays an icon associated with the corresponding position on the seek bar.

At this time, the display control unit 604 may display an icon in a manner corresponding to the number of tags attached to the selected image in association with the corresponding position on the seek bar. The number of tags attached to an image is specified, for example, from the tagging history DB 220.

Here, the number of tags attached to an image is determined by, for example, the number of tags attached to a time period that includes the image among multiple time periods divided by a certain period of time from the start to the end of the video. expressed. The certain period of time can be set arbitrarily, and is set to, for example, about 5 minutes to 10 minutes.

Specifically, for example, the display control unit 604 may display the icon in a color that corresponds to the number of tags. Further, the display control unit 604 may display icons in a pattern according to the number of tags. Further, the display control unit 604 may display the icon in a size corresponding to the number of tags. Further, the display control unit 604 may display the icons with brightness depending on the number of tags. Furthermore, the display control unit 604 may display the icons with a saturation that corresponds to the number of tags.

Depending on the number of tags, the color, pattern, etc. to be used to display the icon can be arbitrarily set in advance. For example, the display control unit 604 may display a red icon if the number of tags attached to an image is a predetermined number or more, and may display a green icon if the number is less than a predetermined number.

In addition, the display control unit 604 associates icons with a mode corresponding to the ratio of the number of specific tags attached to the selected image to the total number of tags attached to the moving images with the corresponding position on the seek bar. May be displayed. Here, the total number of tags attached to a moving image is the total number of tags attached from the start to the end of the moving image.

Further, the number of specific tags attached to an image is represented by, for example, the number of specific tags attached in a corresponding time period. Note that the relevant time period is a time period that includes the image for which the selection has been accepted, from among a plurality of time periods divided at fixed time intervals from the start to the end of the moving image. The specific tag can be set arbitrarily, and is, for example, tag T1 or tag T2.

Tag T1 indicates "I don't know." Tag T2 indicates "Ask a question later." Tags T1 and T2 are tags that tend to be attached, for example, when the user's (student's) level of understanding is low. For example, it can be said that a portion of the lesson video with a large number of tags T1 and T2 is a portion where students have a low degree of understanding.

In addition, the display control unit 604 displays an icon in a form corresponding to the ratio of the number of specific tags attached to the image for which the selection has been accepted to the total number of tags attached to the image for which the selection has been accepted, at the corresponding position on the seek bar. It may be displayed in association with. The number of tags attached to an image is represented by, for example, the number of tags attached in a corresponding time period.

To explain in more detail, for example, the display control unit 604 may determine the color of the icon by referring to coloring reference information 701 as shown in FIG. 7A. Further, the display control unit 604 may determine the size of the icon by referring to size standard information 702 as shown in FIG. 7B.

FIG. 7A is an explanatory diagram showing a specific example of coloring reference information. In FIG. 7A, coloring standard information 701 indicates the correspondence between colors and standards. For example, the display control unit 604 refers to the coloring standard information 701 and changes the color of the icon to "red" when the number of tags T1 and T2 attached in the corresponding time period is 30% or more of the total amount. ” is decided. The total amount corresponds to the total number of tags attached from the start to the end of the video.

In addition, the display control unit 604 refers to the coloring standard information 701, and if the number of tags T1 and T2 attached in the corresponding time period is 10% or more and less than 30% of the total amount, the display control unit 604 controls the coloring of the icon. is set to "yellow". Further, the display control unit 604 refers to the coloring standard information 701, and if the number of tags T1 and T2 attached in the corresponding time period is less than 10% of the total amount and is one or more, the display control unit 604 displays the icon. Set the color to "white". Further, the display control unit 604 refers to the coloring standard information 701, and if the number of tags T1 and T2 attached in the corresponding time period is 0 and the number of other tags is 1 or more, the icon color is set to "green".

Thereby, the display control unit 604 can control the icon so that the color of the icon becomes more reddish as the number of tags T1 and T2 attached to the corresponding time period increases.

FIG. 7B is an explanatory diagram showing a specific example of size reference information. In FIG. 7B, size standard information 702 indicates the correspondence between sizes and standards. For example, the display control unit 604 refers to the size standard information 702 and determines the size of the icon to be "large" if the number of tags attached in the corresponding time period is 20% or more of the total amount. do.

Further, the display control unit 604 refers to the size standard information 702, and if the number of tags attached in the relevant time period is 10% or more and less than 20% of the total amount, the display control unit 604 changes the size of the icon to "medium". ” is decided. Further, the display control unit 604 refers to the size standard information 702 and changes the size of the icon to " Decided on "Small".

Thereby, the display control unit 604 can perform control such that the larger the number of tags attached to the corresponding time period, the larger the size of the icon.

Returning to the explanation of FIG. 6, the second reception unit 603 receives the designation of the first icon among the icons displayed in association with the corresponding position on the seek bar. The designation of the first icon is performed, for example, on a tagging status display screen 800 as shown in FIG. 8, which will be described later. Specifically, for example, the second reception unit 603 receives the designation of the first icon from the teacher's or student's client terminal 201.

In addition, the display control unit 604 associates each tag with the moving image and displays the tag in any one of a plurality of time periods divided by a certain period of time from the start to the end of the moving image. Display the number of each tag attached. Specifically, for example, when receiving the designation of the first icon, the display control unit 604 displays the number of each tag attached to the time period corresponding to the first icon. The number of each tag attached to the time period corresponding to the first icon is specified from the tagging history DB 220, for example.

At this time, the display control unit 604 may display the number of each tag attached to the time period corresponding to the first icon in a table format or a graph format. Further, the display control unit 604 may display the number of each tag attached to the time period corresponding to the first icon in a window different from the window that displays the moving image.

To explain in more detail, for example, when the first icon is specified on the tagging status display screen 800, the display control unit 604 may display a tag window as a pop-up on the tagging status display screen 800. The tag window includes information representing the number of each tag attached to the time period corresponding to the first icon in a table format or a graph format.

Further, the second reception unit 603 may accept the designation of the first tag among the plurality of tags as a result of displaying the number of each tag attached to the time period corresponding to the first icon. The first tag is specified, for example, in the tag window. Specifically, for example, the second reception unit 603 receives the designation of the first tag from the teacher's or student's client terminal 201.

When the display control unit 604 receives the designation of the first tag, it may display a graph representing the change in the number of first tags attached during playback of the video in association with the video. . The transition in the number of first tags is specified, for example, from the tagging history DB 220. Specifically, for example, the display control unit 604 displays the number of first tags attached to each time period of a plurality of time periods divided into fixed time intervals from the start to the end of the moving image in a time series. Display the graph in the tag window.

The display contents of the tag window may be changed depending on, for example, from which client terminal 201, the teacher's or the student's, the designation of the first icon or the designation of the first tag is received. Display examples of the tag window will be described later using FIGS. 9A, 9B, 10A, and 10B.

(Screen example of tagging status display screen 800)
Next, a screen example of the tagging status display screen 800 will be described using FIG. 8. The tagging status display screen 800 is displayed on the teacher's or student's client terminal 201, for example, in response to a video tagging status display instruction from the teacher's or student's client terminal 201.

FIG. 8 is an explanatory diagram showing an example of the tagging status display screen 800. In FIG. 8, a tagging status display screen 800 is an example of an operation screen that visualizes and displays the tagging status of images included in the moving image K3. The tagging status display screen 800 displays a moving image K3 and a seek bar 810.

The moving image K3 is an example of a lesson moving image. The seek bar 810 is a bar that can specify the current reproduction location from the start (numeral 811 in FIG. 8) to the end (numeral 812 in FIG. 8) of the moving image K3. The current playback location is indicated by a slider 813. On the seek bar 810, marks in the shape of an inverted triangle (for example, marks m1 to m4) are displayed at positions corresponding to the images for which the tagging operation has been accepted.

The mark is an example of an icon that indicates the existence of an image for which a tagging operation has been accepted from a student who is a viewer of the moving image K3. Each mark corresponds to a time period including the image for which the tagging operation has been accepted, among a plurality of time periods divided into fixed time periods (for example, 10 minutes) from the start to the end of the moving image K3.

Here, the size of each mark is controlled according to the number of tags attached to each time period. For example, for mark m4, the number of tags attached to the time period corresponding to mark m4 is greater than the number of tags attached to the time period corresponding to other marks m1 to m3. It is larger than the size.

Further, the color of each mark is controlled according to the ratio of the number of tags T1 and T2 attached in each time period to the total number of tags attached to the video image K3 (for example, the color shown in FIG. 7A (See coloring standard information 701). However, in the example of FIG. 8, the difference in color of each mark is expressed by a difference in pattern. For example, the pattern of mark m1 corresponds to green. Further, the pattern of the mark m2 corresponds to white. Further, the pattern of mark m3 corresponds to yellow. Further, the pattern of mark m4 corresponds to red.

For example, assume that the tagging status display screen 800 is displayed on the student's client terminal 201. In this case, by referring to the position corresponding to each mark on the seek bar 810, the user (student) can easily understand the parts of the moving image K3 that have been tagged by himself or other students. Note that the contents of the tagged locations can be confirmed by moving the slider 813 to the position corresponding to each mark.

In addition, by referring to the size of each mark, the user (student) can easily grasp how many students are interested in or have questions about the section. For example, the user (student) can understand from the size of mark m4 that the time period corresponding to mark m4 is a time period in which many students have interests and questions.

Furthermore, by referring to the color of each mark, the user (student) can easily understand where specific tags are concentrated. For example, the user (student) can understand from the color of mark m4 that the time period corresponding to mark m4 is where tags T1 and T2 are concentrated, and that this is the time period where many students have questions. can.

As a result, users (students) can easily see parts of the video K3 that other students are interested in or have questions about, and can notice things they have overlooked and improve their understanding of the lesson. You can deepen it.

Further, on the tagging status display screen 800, if one of the marks (first icon) displayed on the seek bar 810 is selected by the user's (student) operation input using the input device dv2 shown in FIG. , a tag window can be displayed as a pop-up on the tagging status display screen 800.

A display example of the tag window displayed on the student's client terminal 201 will be described later using FIGS. 9A and 9B.

Next, assume that the tagging status display screen 800 is displayed on the teacher's client terminal 201. In this case, the user (teacher) can easily understand the portion of the moving image K3 that has been tagged by the student by referring to the position corresponding to each mark on the seek bar 810.

Furthermore, by referring to the size of each mark, the user (teacher) can easily grasp how many students are interested in or have questions about a particular section. Furthermore, by referring to the color of each mark, the user (teacher) can easily understand where specific tags are concentrated.

From these facts, the user (teacher) can easily know which parts of the moving image K3 the students are interested in or have questions about. For example, users (teacher) can follow up on lessons and improve class videos by accurately understanding the parts that students showed interest in, and parts that were difficult for students to understand due to lack of explanation. can.

Further, on the tagging status display screen 800, if one of the marks (first icon) displayed on the seek bar 810 is selected by the user (teacher) operation input using the input device dv2 shown in FIG. , a tag window can be displayed as a pop-up on the tagging status display screen 800.

A display example of the tag window displayed on the teacher's client terminal 201 will be described later using FIGS. 10A and 10B.

Note that when displaying each mark on the tagging status display screen 800, the information display device 101 does not display information on the user (student) who performed the tagging operation. Thereby, the information display device 101 can prevent other students from knowing the degree of understanding of each student regarding the lesson.

(First display example of tag window)
Next, a display example of the tag window displayed on the student's client terminal 201 will be described using FIGS. 9A and 9B. Here, a display example of a tag window that is displayed when mark m4 is selected by a user (student) operation input on the tagging status display screen 800 shown in FIG. 8 will be described.

9A and 9B are explanatory diagrams showing a first display example of the tag window. In FIG. 9A, the tag window 900 includes a tag list 910 and a tag summary list 920. The tag list 910 includes tags T1 to T5 attached to the time period corresponding to the mark m4 among a plurality of time periods divided into fixed time periods from the start to the end of the moving image K3 shown in FIG. This is information that represents numbers in a tabular format.

According to the tag list 910, the user (student) can accurately grasp the number of each tag T1 to T5 attached to the time period corresponding to the mark m4. For example, a user (student) can accurately grasp how many or how few certain tags there are compared to other tags.

In addition, the tag tally list 920 is a graph showing the number of tags T1 to T5 attached to the time period corresponding to the mark m4 among a plurality of time periods divided into fixed time periods from the start to the end of the moving image K3. This is information expressed in a format.

According to the tag tally list 920, the user (student) can intuitively grasp the number of each tag T1 to T5 attached to the time period corresponding to the mark m4. For example, the user (student) can intuitively understand at what rate each tag was attached during the time period corresponding to mark m4.

Note that the display content of the tag window 900 may be updated, for example, in response to movement of the slider 813 on the seek bar 810 of the tagging status display screen 800. For example, in response to the movement of the slider 813, the information display device 101 displays a tag list 910 and a tag summary list 920 indicating the number of each tag T1 to T5 attached to the time period corresponding to the slider 813. You may.

In the tag window 900, the user (student) can change the number of tags by moving the cursor cr and selecting one of the buttons b1 to b5 using an input device dv2 (see FIG. 2), for example. It is possible to display a graph showing the transition of Buttons b1 to b5 correspond to tags T1 to T5, respectively.

For example, when button b1 is selected, a graph representing changes in the number of tags T1 can be displayed. When button b2 is selected, a graph representing changes in the number of tags T2 can be displayed. When button b3 is selected, a graph representing changes in the number of tags T3 can be displayed. When button b4 is selected, a graph representing changes in the number of tags T4 can be displayed. When button b5 is selected, a graph representing changes in the number of tags T5 can be displayed.

Here, it is assumed that button b1 is selected. In this case, a graph 930 is displayed in the tag window 900, as shown in FIG. 9B. A graph 930 represents a change in the number of tags T1 attached during playback of the moving image K3. Bar 931 corresponds to the time period corresponding to mark m4.

According to the graph 930, the user (student) can understand how the number of tags T1 indicating "I don't understand" changed while playing the moving image K3. For example, the user (student) can see which parts of the video K3 are difficult to understand.

(Second display example of tag window)
Next, a display example of the tag window displayed on the teacher's client terminal 201 will be described using FIGS. 10A and 10B. Here, a display example of a tag window that is displayed when mark m4 is selected by a user (teacher) operation input on the tagging status display screen 800 shown in FIG. 8 will be described.

FIGS. 10A and 10B are explanatory diagrams showing a second display example of the tag window. In FIG. 10A, the tag window 1000 includes a tag list 1010, a tag summary list 1020, a graph 1030, and a student list 1040.

The tag list 1010 includes tags T1 to T5 attached to the time period corresponding to mark m4 among a plurality of time periods divided by fixed time intervals from the start to the end of the moving image K3 shown in FIG. This is information that represents numbers in a tabular format.

According to the tag list 1010, the user (teacher) can accurately grasp the number of each tag T1 to T5 attached to the time period corresponding to the mark m4.

In addition, the tag tally list 1020 is a graph showing the number of tags T1 to T5 attached to the time period corresponding to mark m4 among a plurality of time periods divided into fixed time periods from the start to the end of the video image K3. This is information expressed in a format.

According to the tag tally list 1020, the user (teacher) can intuitively grasp the number of each tag T1 to T5 attached to the time period corresponding to the mark m4.

Further, a graph 1030 represents a change in the number of tags T1 attached during playback of the moving image K3. Note that the graph 1030 is displayed when the button b1 is selected in the tag window 1000. Bar 1031 corresponds to the time period corresponding to mark m4. According to the graph 1030, the user (teacher) can grasp how the number of tags T1 indicating "I don't understand" changed while playing the moving image K3.

The student list 1040 is a list of students who performed the tagging operation with the tag T1 during the time period corresponding to the mark m4. However, in the examples of FIGS. 10A and 10B, some of the students who have performed the tagging operation are excerpted and displayed. The student list 1040 is displayed, for example, when the button b1 is selected in the tag window 1000.

In the student list 1040, student names and the total number of tags are displayed in association with each other. The student name is the name of the student who is the viewer of the moving image K3. The total number of tags is the total number of tags attached during playback of the moving image K3. According to the student list 1040, the user (teacher) can know the students who performed the tagging operation with the tag T1 during the time period corresponding to the mark m4. This allows the user (teacher) to identify students who were unable to understand the content of the lesson during the time period corresponding to mark m4.

Note that although the student list 1040 displays students who performed the tagging operation with the tag T1 during the time period corresponding to the mark m4, the present invention is not limited thereto. For example, the information display device 101 may display a list of students who performed any tagging operation during the time period corresponding to the mark m4 in the student list 1040. Further, the information display device 101 may form a list of all students who participated in the online class and display the list in the student list 1040. Further, in the student list 1040, for example, students who have performed a tagging operation may be sorted in descending order of the total number of tags.

In addition, in the student list 1040, the user (teacher) can, for example, make contact by moving the cursor cr and selecting one of the buttons b11 to b13 using the input device dv2 (see FIG. 2). You can display a window for

For example, when button b11 is selected, a contact window for contacting the student whose student name is "Mr. A" can be displayed. Furthermore, when the button b12 is selected, a contact window for contacting the student whose student name is "Mr. B" can be displayed. Furthermore, when the button b13 is selected, a contact window for contacting the student whose student name is "Mr. C" can be displayed.

Here, it is assumed that the button b11 is selected. In this case, as shown in FIG. 10B, a contact window 1050 is displayed in the tag window 1000. In the communication window 1050, the user (teacher) can send a message to the student whose name is "Mr. A" by inputting the text in the box 1051 and selecting the send button 1052. Note that each student's address is stored in the information display device 101 in association with, for example, the student name and student number.

Thereby, the user (teacher) can contact the student who has added the tag T1 indicating "I don't know" by performing a simple operation of selecting buttons b11 to b13 in the student list 1040, for example. At this time, since there is no need to perform troublesome operations such as inputting a destination address, convenience for the user (teacher) can be improved.

The status of contact with students is managed using a contact status table 1100 as shown in FIG. 11, for example. The contact status table 1100 is realized, for example, by a storage device such as the memory 302 or the disk 304 of the information display device 101.

FIG. 11 is an explanatory diagram showing an example of the contents stored in the contact status table 1100. In FIG. 11, the contact status table 1100 has fields for lecture ID, student number, and sent flag, and by setting information in each field, contact status information (for example, contact status information 1100-1, 1100- 2) is stored as a record.

Here, the lecture ID is an identifier that uniquely identifies a moving image. The student number is an identifier that uniquely identifies the student who is the viewer. The sent flag is a flag indicating the message sending status. The sent flag "0" indicates that the message has not been sent yet. The sent flag "1" indicates that the message has been sent.

For example, suppose that a message is sent to a student whose name is "Mr. A" from the communication window 1050 shown in FIG. 10A. In this case, "1" is set in the sent flag of the contact status information corresponding to the lecture ID "K3" and the student number of the student with the student name "Mr. A."

Thereby, the information display device 101 can determine the contact status of each student by referring to the contact status table 1100 when displaying the student list 1040 as shown in FIG. 10A. For example, assume that the sent flag in the contact status information corresponding to the lecture ID "K3" and the student number of the student with the student name "Mr. A" is set to "1".

In this case, when displaying the student list 1040, the information display device 101 disables the button b11 corresponding to the student with the student name "Mr. A" or displays a label on the button b11 indicating that the student has been contacted. You can

Thereby, the user (teacher) can grasp the status of communication to each student regarding the moving image K3. For example, the user (teacher) can prevent the user (teacher) from accidentally sending the same message multiple times to the student with the student name "Mr. A."

(Tagging history recording processing procedure of information display device 101)
Next, the tagging history recording processing procedure of the information display device 101 will be described using FIG. 12.

FIG. 12 is a flowchart illustrating an example of the tagging history recording processing procedure of the information display device 101. In the flowchart of FIG. 12, first, the information display device 101 determines whether an online class has started (step S1201). Here, the information display device 101 waits for the online class to start (step S1201: No).

If the online class has started (step S1201: Yes), the information display device 101 displays a tagging operation screen on the student's client terminal 201 (step S1202). The tagging operation screen is an operation screen for performing a tagging operation, and corresponds to, for example, the tagging operation screen 500 shown in FIG. 5.

Next, the information display device 101 determines whether a tagging operation for any one of the plurality of images included in the lesson video has been received (step S1203). Here, if the tagging operation is not accepted (step S1203: No), the information display device 101 moves to step S1205.

On the other hand, when a tagging operation is accepted (step S1203: Yes), the information display device 101 records tagging history information about the accepted tagging operation in the tagging history DB 220 (step S1204). The information display device 101 then determines whether the online class has ended (step S1205).

Here, if the online class has not ended (step S1205: No), the information display device 101 returns to step S1202. On the other hand, if the online class has ended (step S1205: Yes), the information display device 101 ends the series of processes according to this flowchart.

Thereby, the information display device 101 can record the operation history regarding the tagging operation performed by the student while playing the class video of the online class. The tagging history information includes, for example, a lecture ID, student number, tag, and elapsed time. Note that the tagging operation for the class video of the online class may be performed in real time during the online class, or may be performed after the online class ends.

(Tagging status display processing procedure of information display device 101)
Next, the tagging status display processing procedure of the information display device 101 will be described using FIG. 13.

FIG. 13 is a flowchart illustrating an example of the tagging status display processing procedure of the information display device 101. In the flowchart of FIG. 13, the information display device 101 first determines whether or not it has received an instruction to display the tagging status of the class video of the online class from the teacher's or student's client terminal 201 (step S1301).

Here, the information display device 101 waits to receive a tagging status display instruction (step S1301: No). When the information display device 101 receives the tagging status display instruction (step S1301: Yes), the information display device 101 extracts tagging history information corresponding to the lecture ID included in the tagging status display instruction from the tagging history DB 220 (step S1301: Yes). S1302).

Next, the information display device 101 refers to the extracted tagging history information and tags each time slot for each of a plurality of time slots that are divided into fixed time intervals from the start to the end of the lesson video. The number for each tag is counted (step S1303).

Then, the information display device 101 determines the size of the mark corresponding to each time period based on the total number of tags for each time period (step S1304). Next, the information display device 101 determines the color of the mark corresponding to each time period based on the total number of tags for each time period (step S1305).

Then, the information display device 101 displays a tagging status display screen on the client terminal 201 (step S1306). The tagging status display screen is an operation screen that displays a lesson video and a seek bar, and corresponds to, for example, the tagging status display screen 800 shown in FIG. 8. A mark of the determined size and color is displayed above each time period on the seek bar.

Next, the information display device 101 determines whether any mark displayed on the tagging status display screen has been selected (step S1307). Here, if no mark is selected (step S1307: No), the information display device 101 moves to step S1309.

On the other hand, if the mark is selected (step S1307: Yes), the information display device 101 executes tag window display processing (step S1308). The specific processing procedure of the tag window display processing will be described later using FIGS. 14 and 15.

The information display device 101 then determines whether the reproduction of the lesson video of the online class has ended (step S1309). Here, if the reproduction of the lesson video has not finished (step S1309: No), the information display device 101 returns to step S1307. On the other hand, if the reproduction of the lesson video has ended (step S1309: Yes), the information display device 101 ends the series of processes according to this flowchart.

Thereby, the information display device 101 can display a mark representing the tagging status of each time slot for each of a plurality of time slots divided into fixed time intervals from the start to the end of the lesson video.

Note that in step S1302, if the tagging history information corresponding to the lecture ID is not extracted, the information display device 101 selects a tagging operation from one or more viewers among the plurality of images included in the lesson video. It is determined that the received image does not exist. In this case, the information display device 101 may, for example, omit the processing of steps S1303 to S1305 and display a tagging status display screen on which no mark is displayed.

Next, the specific processing procedure of the tag window display processing in step S1308 will be explained. First, the specific processing procedure of the first tag window display processing will be described using FIG. 14. The first tag window display process is executed, for example, when a mark displayed on the tagging status display screen is selected on the student's client terminal 201.

FIG. 14 is a flowchart illustrating an example of a specific procedure for the first tag window display process. In the flowchart of FIG. 14, the information display device 101 first extracts tagging history information of the time period corresponding to the mark selected in step S1307 shown in FIG. 13 from the tagging history DB 220 (step S1401).

Note that the tagging history information for the time period corresponding to the selected mark is the time period whose elapsed time corresponds to the selected mark among the tagging history information corresponding to the lecture ID included in the tagging status display instruction. This is tagging history information included in the band.

Next, the information display device 101 generates a tag list that represents, in a table format, the number of each tag attached to the selected mark in the time period corresponding to the selected mark, based on the extracted tagging history information (step S1402 ). Next, the information display device 101 generates a tag summary list that represents the number of each tag attached to the selected mark in the time period corresponding to the selected mark in a graph format based on the extracted tagging history information (step S1403). ).

Then, the information display device 101 displays a tag window including the generated tag list and tag total list (step S1404). Next, the information display device 101 determines whether any one of the plurality of tags is selected in the tag window (step S1405).

Here, if no tag is selected (step S1405: No), the information display device 101 returns to the step that called the first tag window display process.

On the other hand, if a tag is selected (step S1405: Yes), the information display device 101 extracts tagging history information corresponding to the selected tag from the tagging history DB 220 (step S1406). Note that the tagging history information corresponding to the selected tag is tagging history information corresponding to the lecture ID included in the tagging status display instruction and the selected tag.

Next, the information display device 101 generates a transition graph representing the transition in the number of selected tags added during playback of the lesson video, based on the extracted tagging history information (step S1407). Then, the information display device 101 displays the generated transition graph in the tag window (step S1408), and returns to the step that called the first tag window display process.

As a result, the information display device 101 displays information (tag list, tag tally list) representing the number of each tag attached in the time period corresponding to the mark selected on the tagging status display screen in a separate window. be able to. Further, the information display device 101 can display a transition graph representing a transition in the number of tags attached during playback of a lesson video, for tags selected from a plurality of tags.

Next, the specific processing procedure of the second tag window display processing will be explained using FIG. 15. The second tag window display process is executed, for example, when a mark displayed on the tagging status display screen is selected on the teacher's client terminal 201.

FIG. 15 is a flowchart illustrating an example of a specific procedure for the second tag window display process. In the flowchart of FIG. 15, the information display device 101 first extracts tagging history information of the time period corresponding to the mark selected in step S1307 shown in FIG. 13 from the tagging history DB 220 (step S1501).

Next, the information display device 101 generates a tag list that represents, in a table format, the number of each tag attached to the selected mark in the time period corresponding to the selected mark, based on the extracted tagging history information (step S1502 ). Next, the information display device 101 generates a tag summary list that represents the number of each tag attached to the selected mark in the time period corresponding to the selected mark in a graph format based on the extracted tagging history information (step S1503 ).

Then, the information display device 101 displays a tag window including the generated tag list and tag total list (step S1504). Next, the information display device 101 determines whether any one of the plurality of tags has been selected in the tag window (step S1505).

Here, if no tag is selected (step S1505: No), the information display device 101 returns to the step that called the second tag window display process.

On the other hand, if a tag is selected (step S1505: Yes), the information display device 101 extracts tagging history information corresponding to the selected tag from the tagging history DB 220 (step S1506). Next, the information display device 101 generates a transition graph representing the transition in the number of selected tags added during playback of the lesson video, based on the extracted tagging history information (step S1507).

Next, the information display device 101 refers to the tagging history DB 220 and generates a list of students who have performed the tagging operation with the selected tag during the time period corresponding to the selected mark. (Step S1508). The student list is, for example, the student list 1040 shown in FIG. 10A.

Then, the information display device 101 displays the generated transition graph and student list in the tag window (step S1509), and returns to the step that called the second tag window display process.

As a result, the information display device 101 displays information (tag list, tag tally list) representing the number of each tag attached in the time period corresponding to the mark selected on the tagging status display screen in a separate window. be able to. In addition, the information display device 101 displays a transition graph representing the transition in the number of tags attached during playback of the lesson video and a list of students who have performed the tagging operation for the tag selected from the plurality of tags. A list of students can be displayed.

As described above, according to the information display device 101 according to the second embodiment, when displaying a moving image, one or more viewers of the moving image select from among a plurality of images included in the moving image. If there is an image whose selection has been accepted on the seek bar, a seek bar and an icon associated with the position corresponding to the image whose selection has been accepted on the seek bar can be displayed. The seek bar is a bar that allows you to specify the current playback location from the start to the end of the video.

Thereby, the information display device 101 can visualize a portion of the moving image for which selections have been received from one or more viewers. For example, when displaying a moving image, the information display device 101 can display in an easy-to-understand manner which part the viewer is interested in or has questions about, so that the viewer can efficiently check the content of the moving image. I can do it.

Further, according to the information display device 101, icons in a mode corresponding to the number of tags attached to the selected image can be displayed in association with the corresponding position. Selection of images is a tagging operation. Further, the corresponding position is a position on the seek bar that corresponds to the image for which the selection has been accepted.

Thereby, the information display device 101 can easily display, for example, a portion of a moving image that has been tagged with a large number of tags and that many viewers have expressed interest or doubts about.
