An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an outline of a video education system according to an embodiment of the present invention.
The video education system of this example includes a distribution server 10 that distributes lecture videos and a video playback device 20 that receives and plays lecture videos from the server 10.

The distribution server 10 is a device used by a lecture video distributor, a lecture video DB for managing a lecture video to be distributed, a student DB for managing a student (user) who views the lecture video, and a viewing result of the lecture video. A viewing result DB to be managed is provided.
The distribution server 10 may be configured by a single device, or may be configured by distributing each function to a plurality of devices.

  The video playback device 20 is a user terminal device used by a user who views a lecture video, and various types of stationary and portable terminal devices that can communicate with the distribution server 10 by wire or wireless can be used. Examples of the portable terminal device include a mobile PC, a tablet PC, a mobile phone, a smartphone, and the like.

FIG. 2 shows an example of the processing flow of the video playback device 20.
The video playback device 20 requests the distribution server 10 for a lecture video that the user desires to view, and receives the lecture video distributed from the distribution server 10 in response to this (S1).
Next, the reproduction of the lecture video received from the distribution server 10 is started (S2).

Thereafter, during the reproduction of the lecture video, the presence / absence of a specific operation indicating the user's reaction to the content of the lecture video (in this example, the understanding of the lecture content is insufficient) is monitored (S3).
When a specific operation is detected (S3; Yes), the moving image playback time and moving image capture (moving image) at that time are acquired (S4), and the acquired moving image playback time and moving image capture are stored in the memory inside the apparatus. (S5). Here, the moving image capture is a snapshot image (still image) obtained by shooting a video at a certain point in the moving image.
The processes of S3 to S5 are repeated until the reproduction of the lecture video is finished (S6).

When the playback of the lecture video is finished (S6; Yes), if one or more specific operations are detected during the playback of the lecture video, the accumulated video capture and video playback time list is displayed in the order of the video playback time. It is displayed (S7), and the input of the question text relating to the video capture selected by the user is received (S8).
Thereafter, the detection notification of the specific operation is transmitted to the server in association with the accumulated moving image reproduction time history, the selected moving image capture, and the question text relating to the moving image capture (S9).

  When the distribution server 10 receives the detection notification of the specific operation from the moving image playback device 20, the distribution server 10 displays the history of the moving image playback time, the selected moving image capture, and the question text related to the moving image capture transmitted in association with this in the viewing result DB. Remember. These pieces of information are stored in association with the identification information of the user of the video playback device 20 (that is, the student who has viewed the lecture video).

The moving image capture and the question sentence stored in the viewing result DB are browsed by the teacher in charge. Since the teacher in charge can view the video capture together with the question text, it is easy to grasp what content the lecture video is about. The teacher in charge responds to the question text from the user at the place of contact with the user such as a cram school or an individual classroom, or through a communication means such as e-mail.
Further, the history of the video playback time stored in the viewing result DB is information for identifying a part of the lecture video that is not fully understood by the user, and can be used for the subsequent creation of the lecture video. It is also possible to analyze which lecture videos are being viewed by other users who have the same level of understanding as that user, and to help select the lecture videos that the user is recommended to view next. .

FIG. 3 shows an example of a video playback screen by the video playback device 20.
In the moving image playback screen of this example, a specific operation button 32 is provided in the moving image playback area 31, and the specific operation button 32 is responded to when the user presses (clicks) the specific operation button 32 during playback of the moving image. Is detected as a specific operation, and the moving image playback time and moving image capture at that time are acquired and stored in the memory inside the apparatus.

  In the case of using a portable terminal device (for example, a smartphone) provided with vibration detecting means such as an acceleration sensor that detects acceleration applied to the device as the video playback device 20, the device is shaken during video playback. Can be detected by assuming that the shake of the apparatus is a specific operation, and the moving image reproduction time and moving image capture at that time can be acquired and stored in the memory inside the apparatus. In this case, in order to allow the user to recognize that the shake of the device has been detected as a specific operation, a distinctive sound is generated when a specific operation based on the shake is detected, or a predetermined detection mark is displayed on the screen. Notification may be performed.

FIG. 4 shows an example of a specific operation list screen by the moving image playback device 20.
In the specific operation list screen of this example, a list of reduced images (thumbnail) and video playback time of the video capture acquired each time a specific operation is detected during video playback is selected by the user in order of video playback time. Display in a possible format. Selection by the user is performed by pressing (clicking) a question button 41, a delete button 42, and a play button 43 provided for each list.

When the question button 41 is pressed, a question text input screen relating to the list is displayed, and the input of the question text is accepted.
When the delete button 42 is pressed, the list is deleted from the list display, and the corresponding video playback time and video capture are deleted from the memory inside the apparatus. In this case, if the user performs a specific operation by mistake, the specific operation is canceled afterwards.
When the play button 43 is pressed, the moving image is replayed starting from a time point that is a predetermined time after the moving image playing time. As a result, the user can review, for example, a part for which understanding is insufficient. Note that the moving image may be divided into a plurality of sections, and the moving image may be replayed from the beginning of the section including the moving image playing time of the list in which the play button 43 is pressed. As a result, if the moving image is divided into sections with a unit of content, the user can easily understand the content when reviewing from the middle of the moving image.

  In this example, the specific operation list screen is automatically displayed after the reproduction of the moving image on the moving image reproduction screen. However, in response to the instruction from the user to display the specific operation list screen from the user, A specific operation list screen may be displayed.

  In addition, a specific operation history transmission button (not shown) is provided on the specific operation list screen, and when a specific operation history transmission button is pressed by the user, a detection notification of the specific operation is sent to the video playback time. Are transmitted to the distribution server 10 in association with the history. When there is an input of a question text related to the displayed list, the question text and the corresponding video capture are also transmitted to the distribution server 10. Note that the specific operation history transmission button may not be provided, and a specific operation detection notification may be transmitted to the distribution server 10 in response to the closing of the specific operation list screen.

FIG. 5 shows an example of a question sentence input screen by the moving image playback apparatus 20.
The question sentence input screen of this example includes a moving picture capture display area 51, a moving picture capture save button 52, a question sentence input unit 53, and a question confirmation button 54.

The video capture save button 52 is a button for instructing to save the video capture displayed in the video capture display area 51. When the moving image capture save button 52 is pressed, the corresponding moving image capture is stored in another area of the memory inside the apparatus so that it can be referred to later.

The question sentence input unit 53 is an area where the user inputs a question sentence related to the content of the moving image near the moving image capture displayed in the moving image capture display area 51.
The question confirmation button 54 is a button for instructing confirmation of the question text input to the question text input unit 53. When the question confirmation button 54 is pressed, the question text input to the question text input unit 53 is stored in the internal memory in association with the corresponding video playback time and video capture, and the question text input screen is closed. Return to the specific operation list screen.

  As described above, the video playback device 20 of the present example detects a specific operation indicating a user's reaction to the content of the video during the playback of the video, and acquires the playback time of the video when the specific operation is detected. Then, a detection notification indicating that the specific operation has been detected is transmitted to the server 10 in association with the playback time of the moving image. For this reason, it becomes possible to grasp the user's reaction to the content of the moving image during the reproduction of the moving image on the server side. Here, the above example deals with a reaction that the understanding of the video content is insufficient, but there are various reactions such as a reaction that the video content is fully understood and a response that the video content is sympathetic. Can be applied to.

  Moreover, when using a portable terminal device as the moving image reproducing device 20, an operation of shaking the portable terminal device is detected as a specific operation. For this reason, the user who is watching the moving image can simply notify the server side that the user has some reaction to the content of the moving image at that time simply by shaking the portable terminal device. Here, the shake of the portable terminal device is not only an operation in which the user shakes the portable terminal device with his / her hand, but also an operation such as an operation of applying vibration by hitting the portable terminal device with a fingertip. The operation includes generating various types of vibrations that can be detected by the portable terminal device.

  In the detection of the specific operation, the intensity of the specific operation may also be detected and transmitted to the server 10 in association with the detection notification of the specific operation. This makes it possible to notify the server side of the degree of user reaction. Here, as the strength of the specific operation, for example, the number of clicks of the specific operation button 32 within a predetermined time, the number of shakes of the video playback device 20 within a predetermined time, the measured value of the shake momentum of the video playback device 20, etc. A classification value obtained by classifying these measurement values based on a predetermined standard can be used.

In addition, the moving image playback apparatus 20 of this example acquires a moving image (moving image capture) at the time when the specific operation is detected, and the acquired moving image and reproduction time each time the specific operation is detected. The list is displayed in a format that can be selected by the user, data input is received from the user for the list selected from the list, and the detected data related to the selected list is associated with the input data to the server 10. Send. For this reason, the user can input data about a part having some reaction during the reproduction of the moving image and notify the server side. Data can be input by various input methods such as voice input as well as text format input. Further, the data may be not only questions about the content of the moving image but also opinions and impressions about the content of the moving image, and various information regarding the content of the moving image can be input.
In addition, the moving image playback device 20 of this example transmits the image of the moving image in the list to the server 10 in association with the detection notification related to the selected list. For this reason, it becomes easy for a person who has seen the data received from the moving image playback device 20 to understand which content in the moving image is the input data.

  Here, in the above description, a specific operation is detected during the reproduction of the moving image, the history is accumulated, and after the moving image is reproduced, it is presented to the user together with the moving image capture in a list format to accept data input. The data input may be accepted in response to the detection of the specific operation during the reproduction of the moving image.

  In other words, the video playback device 20 acquires the playback time of the video at the time when the specific operation is detected in response to the detection of the specific operation during playback of the video, and temporarily stops the playback of the video and asks the question. Calls the sentence input screen and accepts data input from the user. When the user finishes inputting data, the video playback device 20 transmits a detection notification indicating that the specific operation has been detected to the server 10 in association with the playback time of the video and the input data. Resume playback of. Thereby, the user of the moving image reproduction device 20 can input data (for example, a question sentence) and transmit it to the server 10 at any time during viewing of the moving image.

Even in this case, if the moving image playback device 20 acquires the image of the moving image at the time when the specific operation is detected and transmits the image to the server 10 in association with the detection notification, the moving image playback device 20 receives the image from the moving image playback device 20. It becomes easy for a person who has seen the input data (for example, a teacher in charge) to understand which content in the video is the input data. Further, since the playback time of the moving image is also transmitted to the server 10, the moving image can be played back and provided to a person who views the input data received from the moving image playback device 20 from the time when the specific operation is detected. It should be noted that a video is played starting from a point that is a predetermined time after the point when a specific operation is detected, or the beginning of a section that includes a point when a specific operation is detected for a video that has been divided into multiple sections. You may make it reproduce a moving image from.
In consideration of the possibility of unintentional vibration being applied to the portable terminal device, when a shake is detected, the question text input screen is not called immediately after the video playback is paused. Inquires the user whether or not the sentence input screen can be called, calls the question sentence input screen when there is a clear instruction to call, and inputs a question when there is an instruction to cancel (cancel) You may make it resume reproduction | regeneration of a moving image, without calling a screen.

  Further, instead of detecting a specific operation only during reproduction of a moving image, an operation with the same manner may be detected during non-reproduction of the moving image to receive data input. That is, the shake is detected regardless of whether or not the moving image is being reproduced, and the subsequent processing contents are changed depending on whether or not the moving image is being reproduced when the shake is detected.

  Specifically, for example, in a configuration in which a portable terminal device is used as the moving image playback device 20 and an operation of shaking the portable terminal device is detected as a specific operation, an operation (shaking) that is the same as the specific operation even during non-playback of a moving image. ), And accepting data input from the user in response to the detection of the shake of the portable terminal device during non-playback of the video, and input of an image including a problem to be questioned A notification indicating that a shake of the portable terminal device has been detected is transmitted to the server 10 together with data and an image input by the user.

  According to such a configuration, when a user who uses a portable terminal device as the moving image playback device 20 has a question about an object other than a moving image (for example, a text teaching material), the portable terminal device is shaken to obtain data ( For example, by calling a question text input screen for accepting input of a question text) and an image and inputting data and an image, the input data and the image can be transmitted to the server 10 together with a shake detection notification. The image may be input by calling the shooting application from the above input screen and shooting the target on the spot, or by inputting the target image that has been shot in advance from the memory. May be. The image of the object is not limited to an image obtained by photographing a physical object, and may be an electronic object such as snapshot images of various sites that can be browsed through the Internet.

The question text input screen of this example has a subject selection unit 61, an image input unit 62, a question text input unit 63, and a question confirmation button 64, and an operation in the same manner as a specific operation is detected during non-playback of a moving image. Called in response to what has been done. In consideration of the possibility of unintentional vibration being applied to the portable terminal device, is it possible to call the question text input screen instead of calling the question text input screen immediately when a shake is detected? The question message input screen may be called when a user is inquired of whether or not and there is a clear instruction to call.

The subject selection unit 61 is an area that accepts selection of a subject to be questioned from the user. In the example of FIG. 6, it is possible to select from five subjects of English, mathematics, Japanese language, science, and society, but these are only examples, and various subjects can be selected.
The image input unit 62 is an area for receiving an input of an image related to the question from the user. In this example, when an area of the image input unit 62 is touched, an image of an object that has been captured in advance can be specified and input from the memory. You may make it input by another method, such as photographing a target object in the field. Note that the input of an image may be omitted in consideration of a question in which the content can be sufficiently understood without adding an image.

The question sentence input unit 63 is an area where the user inputs a question sentence about the subject selected by the subject selection unit 61.
The question confirmation button 64 is a button for instructing confirmation of the question sentence input to the question sentence input unit 63. When the question confirmation button 64 is pressed, each information of the subject selected by the subject selecting unit 61, the image input to the image input unit 62, and the question sentence input to the question sentence input unit 63 is included in the portable terminal device.
