In the present embodiment, the questioner can transmit captured image data (question image data) obtained by capturing the handwritten question content with the camera unit 14 to the management server 3 as question data. The external communication unit 15 performs data communication with an external device such as the management server 3 through the communication network under the control of the control unit 11.

  Similarly to the questioner terminal 1, the respondent terminal 2 includes the CPU 21, the ROM, the RAM, and the like. The operation unit 22 is also a touch panel type like the questioner terminal 1, receives various operation inputs from the respondent, and sends the received operation input contents to the control unit 21. The display unit 23 displays an image on the touch panel under the control of the control unit 21. The camera unit 24 images a predetermined imaging area under the control of the control unit 21 and sends the captured image data to the control unit 21. In the present embodiment, the respondent can transmit captured image data (answer image data) obtained by capturing the handwritten answer content with the camera unit 14 to the management server 3 as answer data. The external communication unit 25 performs data communication with an external device such as the management server 3 through the communication network under the control of the control unit 21.

  The control unit 31 in the management server 3 is also configured by a CPU, a ROM, a RAM, and the like, and controls each unit constituting the management server 3 and performs various data processing.

  Further, the question image data storage unit 32 of the management server 3 stores the question image data received from the questioner terminal 1 via the communication network under the control of the control unit 31. Each question image data in the present embodiment is stored in association with the student ID (questioner specifying information) of the questioner who uses the questioner terminal 1 that transmitted the question image data. Further, in this embodiment, as will be described later, each question image data is classified for each lecture (group) related to the question, and therefore is associated with a lecture ID (group specifying information) for specifying the lecture. And memorized.

  In addition, the answer image data storage unit 33 of the management server 3 stores the answer image data received from the respondent terminal 2 through the communication network under the control of the control unit 31.

Each answer image data is also stored in association with the student ID (questioner specifying information) of the questioner who uses the questioner terminal 1 that transmitted the corresponding question image data. As a result, each answer image data is stored in association with the lecture ID into which the corresponding question image data is classified.

  The point storage unit 34 of the management server 3 functions as a question number remaining amount information storage unit and an evaluation acquisition amount information storage unit, and as question number remaining amount information of each questioner in association with the student ID and the respondent ID. Point data and point data as evaluation acquisition amount information of each respondent are stored. In the present embodiment, the number-of-questions remaining amount information and the evaluation acquisition amount information are point data having quantity information of the same dimension, but may be quantity information of different dimensions. However, even in this case, it is preferable that the number-of-questions remaining amount information and the evaluation acquisition amount information be quantity information that can be converted into each other.

  The point data stored in the point storage unit 34 is increased or decreased by a point subtraction process as a question number remaining amount reduction process or a point addition process as an evaluation acquisition amount information increase process executed by the control unit 31. In this embodiment, each student is given a predetermined amount of points (remaining number of questions) according to the number of lectures that the student takes, for example, and each student (questioner) When asking questions, pay points and ask questions. Each respondent is given a predetermined amount of points (evaluation acquisition amount) when an answer that has received a predetermined or higher evaluation from the questioner is made. The method of using the points acquired by the respondent is arbitrary.

  The external communication unit 35 of the management server 3 performs data communication with external devices such as the terminals 1 and 2 via the communication network under the control of the control unit 31.

Next, processing of the video education system in this embodiment will be described.
FIG. 3 is a flowchart showing the flow of processing of the video education system including question registration processing of the question answering system in the present embodiment.
The management server 3 publishes a video education system website that can be accessed from the terminals 1 and 2 via the communication network. The students (questioners) and respondents can use the terminals 1 and 2 to A website can be accessed. A student who accesses the Web site uses the terminal 1 to input login information such as a student ID and a password. Then, the login information is transmitted to the management server 3 via the communication network. The management server 3 that has received the login information transmits the information for displaying the lecture selection screen to the terminal 1 that is the transmission source of the login information after executing the authentication process by the control unit 31. Thereby, the lecture selection screen is displayed on the display unit 13 of the terminal 1.

  When the student selects a lecture that the student wants to attend according to the lecture selection screen displayed on the display unit 13 of the terminal 1, the lecture selection information is transmitted to the management server 3 via the communication network. Upon receiving the lecture selection information, the management server 3 causes the control unit 31 to execute video distribution processing for distributing a lecture video corresponding to the lecture selection information. Thereby, the video data of the lecture related to the lecture selection information is transmitted to the terminal 1 that is the transmission source of the lecture selection information. Then, the lecture video selected by the student is displayed on the display unit 13 of the terminal 1, and the student can view the lecture through the terminal 1.

  When viewing of the lecture by the student ends, the display unit 13 of the terminal 1 displays an understanding level selection screen for allowing the student to select an understanding level of the lecture content. This understanding level selection screen, for example, prompts selection of two choices of “I understand (OK)” and “I can't understand (NG)”. When the student selects an understanding level according to the understanding level selection screen, the understanding level selection information is transmitted to the management server 3 via the communication network. If the understanding level selection information is “I understand (OK)”, the management server 3 that has received the understanding level selection information ends the lecture video distribution and displays the lecture selection screen on the terminal 1 again. Information is transmitted, and a lecture selection screen is displayed on the display unit 13 of the terminal 1.

  On the other hand, if the understanding level selection information is “Unrecognizable (NG)”, the management server 3 uses the control unit 31 to display information for displaying a question input screen on the terminal 1 that has transmitted the understanding level selection information. Send. Thereby, the question input screen is displayed on the display unit 13 of the terminal 1. On this question input screen, for example, the student selects whether to input text using a keyboard or the like, whether to use a camera input for capturing a handwritten question with a camera, or not to ask a question.

  When the student selects camera input according to the question input screen, the control unit 11 of the terminal 1 activates the camera unit 14 and transmits captured image data (question image data) captured by the camera unit 14 to the management server 3. The question input process is executed. In this question input process, the imaging area of the camera unit 14 is displayed on the display unit 13 of the terminal 1 and a release operation button is displayed on the display unit 13. When a student inputs the contents of a handwritten question with a camera, first, the release operation button on the display unit 13 is touched with a finger and the state is continuously maintained. When the operation content is received by the operation unit 12, the control unit 11 performs the autofocus function of the camera unit 14 while the release operation button is being touched to focus the question content. When the student performs an operation of releasing his / her finger from the release operation button on the display unit 13, the operation content is received by the operation unit 12, and the control unit 11 captures an image on the camera unit 14 in accordance with the operation timing. The captured image data including the question content is acquired from the camera unit 14.

  In the present embodiment, the release operation is performed according to the operation timing when the student releases his / her finger from the release operation button on the display unit 13, but the student operates the release operation button on the display unit 13. The release operation may be performed according to the operation timing of touching with a finger. However, the operation of touching with a finger tends to increase the movement (blurring) of the terminal 1 of the student who performs the operation compared to the operation of releasing the finger. Therefore, performing the release operation in accordance with the operation timing when the finger is released from the release operation button as in the present embodiment has an advantage that the blur of the captured image and the shift of the focus are reduced.

  The control unit 11 of the terminal 1 performs various image processing on the captured image data acquired from the camera unit 14 and then performs data compression processing to associate the question image data with the student ID and lecture ID. Transmit to the management server 3. The image processing performed here is not particularly limited, but necessary image processing is appropriately performed from the viewpoint of reducing the amount of data communication with the management server 3 and managing question image data in the management server 3. Specific examples include perspective conversion processing for converting perspective image data obtained by obliquely photographing a sheet describing the contents of a question into front-view image data, and color reduction processing for reducing the amount of data. In addition to the binarization process, the color reduction process includes a process of reducing the color to, for example, three colors of black, white, and red. When reducing to three colors of black, white, and red, for example, a red detection process is performed to extract a red image and a non-red image, and a process in which binarization processing is performed on each image is combined Can be realized.

  The question image data transmitted from the terminal 1 in this way is received by the external communication unit 35 and the control unit 31 as information receiving means of the management server 3. Here, in the present embodiment, the control unit 31 of the management server 3 functions as a point process execution unit and is associated with the student ID of the student (questioner) who uses the terminal 1 that is the source of the question image data. Then, a point subtraction process for subtracting a predetermined point from the point data in the point storage unit 34 is executed. That is, in this embodiment, each student (questioner) pays his / her points when asking questions regarding the contents of each lecture. Note that the amount of points to be subtracted at the time of question is 10 points here, but can be arbitrarily set.

  At this time, if the point data associated with the student ID corresponding to the question image data is less than the point amount to be subtracted at the time of the question, a processing result notification indicating that the point subtraction process cannot be completed, Transmit to the terminal 1. Thereby, a notification that the registration of the question could not be completed due to insufficient points is displayed on the display unit 13 of the terminal 1. Thereafter, the management server 3 ends the lecture video distribution, transmits information for displaying the lecture selection screen to the terminal 1 again, and displays the lecture selection screen on the display unit 13 of the terminal 1.

  On the other hand, when the control unit 31 completes the process of subtracting the points to be subtracted at the time of the question from the point data associated with the student ID corresponding to the question image data, the question image data storage unit stores the question image data. The question registration process to be registered in 32 is executed. In this question registration process, the question image data is registered in the question image data storage unit 32 in association with the student ID and lecture ID corresponding to the question image data. Thereafter, the management server 3 transmits a processing result notification to the terminal 1 that is the transmission source of the question image data by the control unit 31. As a result, a notification that the registration of the question is completed is displayed on the display unit 13 of the terminal 1. Thereafter, the management server 3 ends the lecture video distribution, transmits information for displaying the lecture selection screen to the terminal 1 again, and displays the lecture selection screen on the display unit 13 of the terminal 1.

When text input using a keyboard or the like is selected in accordance with the question input screen, the content of the text input by the student is transmitted as question data to the management server 3 in association with the student ID and lecture ID. As a result, the question data input as text is also registered in the question image data storage unit 32 as in the case of the question image data.
If the student selects not to ask a question according to the question input screen, the lecture video distribution ends without performing the question registration process, and information for displaying the lecture selection screen on the terminal 1 is transmitted again. Then, the lecture selection screen is displayed on the display unit 13 of the terminal 1.

  According to this embodiment, the question image data from the questioner terminal 1 of the student (questioner) with insufficient points is not registered (not accepted) in the question image data storage unit 32. For this reason, the number of times that the question image data from each student (questioner) can be registered is limited within a certain range. Specifically, in the present embodiment, as described above, a predetermined amount of points according to the number of lectures attended by the student is given to each student, for example. Here, 30 points are given per lecture, but can be arbitrarily set. In this embodiment, since the amount of points to be subtracted in the above-described question is 10 points, on average, question image data can be registered three times per lecture. However, the amount of points given per lecture In addition, the number of registrations of question image data can be arbitrarily adjusted by appropriately setting the amount of points to be subtracted at the time of a question.

  As described above, in the present embodiment, the number of registrations of the question image data from each student (questioner) is limited, and as a result, many questions including inappropriate questions are overburdened to the questioner. Can be encouraged to ask questions by focusing on appropriate questions. As a result, it is possible to reduce inappropriate questions that prevent proper answers or quick answers by respondents.

  In addition, in the present embodiment, the number of registrations of the question image data can be adjusted by setting a point grant amount per lecture, a point amount to be subtracted at the time of a question, or the like. Therefore, it is possible to control how much the registration number of the question image data is limited by the administrator side of the question answering system of the present embodiment. This makes it possible to achieve a balance that can reduce inappropriate questions without unduly limiting appropriate questions.

  In this embodiment, the method of registering the question image data by the student is limited to the method of registering the question image data from the student by displaying the question input screen at the end of the lecture viewing as described above. Absent. For example, the logged-in student performs an operation for inputting a predetermined question on the website (for example, touching a question input button displayed on the lecture selection screen, etc.), so that the above-described question input screen is displayed. Also included is a method of registering the question image data from the student to be displayed.

Next, the presentation of answers in the present embodiment will be described.
FIG. 4 is a flowchart showing the flow of answer presentation processing of the question answering system in the present embodiment.
The respondent who has accessed the Web site published by the management server 3 uses the terminal 2 to input login information such as the respondent ID and password. Then, the login information is transmitted to the management server 3 via the communication network. After receiving the login information, the management server 3 executes the authentication process by the control unit 31, and then the control unit 31 of the management server 3 identifies and identifies the lecture ID associated with the respondent ID related to the login information. A process of extracting the question image data registered in association with the lecture ID from the question image data storage unit 32 is performed. The association between the respondent ID and the lecture ID is, for example, by associating the lecture ID corresponding to the lecture or the course selected by the respondent when applying for the respondent with the respondent ID of the respondent. Can be obtained.

  Then, the control unit 31 of the management server 3 displays information for displaying a question selection screen for selecting an answer target from the extracted question image data as a terminal of a login information transmission source. 2 to send. Thereby, the question selection screen is displayed on the display unit 23 of the terminal 2. The question selection screen includes one or more question image data associated with the lecture ID corresponding to the respondent ID of the respondent, that is, one or more questions about the lecture that the respondent can answer. Image data is displayed. In addition, on this question selection screen, selection of which question image data the question is to be answered, and as the answering method, text input using a keyboard or the like, or camera input for imaging a handwritten answer with a camera Or not to answer.

  When the respondent selects the question image data to be answered according to the question selection screen and selects the camera input, the control unit 21 of the terminal 2 activates the camera unit 24 and the captured image data captured by the camera unit 24. An answer input process for transmitting (answer image data) to the management server 3 is executed. This answer input process is the same as the question input process in the questioner terminal 1 described above. The control unit 21 of the terminal 2 performs various image processes on the captured image data acquired from the camera unit 24, Compression processing is performed, and the response image data is transmitted to the management server 3 in association with the respondent ID and lecture ID.

  The reply image data transmitted from the terminal 2 is received by the external communication unit 35 and the control unit 31 as information receiving means of the management server 3. Thereby, the control unit 31 of the management server 3 executes an answer registration process for registering the answer image data in the answer image data storage unit 33. In this answer registration process, the answer image data is registered in the answer image data storage unit 33 in association with the question image data corresponding to the answer image data, the answerer ID, and the lecture ID.

  In the present embodiment, the question image data is presented to the respondent who has accessed the website, and the answer target is selected and the answer is input. For example, if the question image data is registered, The question image data may be push-distributed from the management server 3 to the respondent terminal 2 of the respondent ID associated with the lecture ID corresponding to the question image data. Further, for example, when the question image data is registered, the management server 3 informs the respondent terminal 2 of the respondent ID associated with the lecture ID corresponding to the question image data that the question has been registered. It is also possible to push-distribute information to urge the respondent to access the website.

  On the other hand, for the logged-in student (questioner), the control unit 31 of the management server 3 displays the question image data registered in association with the student ID related to the login information. The answer image data extracted from the answer image data and the answer image data associated with the question image data is extracted from the answer image data storage unit 33. And the information for displaying the question answer screen which presents these question image data and answer image data is transmitted. Thereby, the question answer screen including the question contents asked by the student (questioner) and the answer contents answered by the answerer is displayed on the display unit 13 of the terminal 1. As a result, the student can confirm the content of the answer to the question he asked.

  In addition, on this question answer screen, selection of whether or not the presented answer contents are appropriate is selected, for example, two choices of “I understand (OK)” and “I cannot understand (NG)” Prompt. When the student selects evaluation according to the question answer screen, the answer evaluation information is transmitted to the management server 3 via the communication network. If the answer evaluation information is “Unrecognizable (NG)”, the management server 3 that has received the answer evaluation information transmits an evaluation result notification indicating that to the terminal 2 that has transmitted the answer image data. Thereby, a notification that the answer evaluation is low is displayed on the display unit 23 of the terminal 2.

  On the other hand, when the response evaluation information is “I understand (OK)”, the control unit 31 of the management server 3 functions as a point processing execution unit and uses the terminal 2 that is the transmission source of the response image data. A point addition process of adding a predetermined point to the point data in the point storage unit 34 associated with the respondent ID is executed. That is, in this embodiment, the respondent can obtain points by receiving high evaluation from the questioner regarding his / her answer content. Thereby, it is possible to prompt the respondent to get a better answer.

  Here, in this embodiment, the point amount to be added to the respondent in the point addition process is larger than the point amount paid by the questioner when registering the question image data (that is, the point amount subtracted by the point subtraction process). For example, 8 points. As a result, it is possible to perform point processing in which a part of the point amount reduced from the questioner's points is added to the respondent's points and the rest is received by the system administrator. According to such point processing, the point balance of the entire system is clear and appropriate system operation can be realized.

  In this embodiment, the answer image data is presented to the questioner who accesses the website. For example, if the answer image data is registered, the answer image data is associated with the answer image data corresponding to the answer image data. The response image data may be push-distributed from the management server 3 to the terminal 1 of the questioner with the questioner ID. Further, for example, if the answer image data is registered, the management server 3 indicates that the answer has been registered to the questioner's terminal 1 having the questioner ID associated with the question image data corresponding to the answer image data. Information to be guided may be distributed by push to prompt the questioner to access the website.

  Moreover, in this embodiment, as above-mentioned, the question content of a questioner is shown to a respondent by the question image data which imaged the handwritten question content. In order to appropriately convey the contents of the question and the intention of the question to the respondent, the text information alone may be insufficient or inappropriate. For handwritten question images that contain analog information other than character information (character size and position, character color, pen pressure, symbols such as ○ and underline), the question information with only character information is insufficient or inappropriate. It is also possible to convey adequately or appropriately to the respondents about the contents of questions. Further, the questioner can ask a question by writing the contents of the question by hand on a sheet at hand, capturing it with the camera unit 14 of the terminal 1, and transmitting the question image data. Such an operation can be performed more easily and quickly than the operation of inputting text using the keyboard of the interrogator terminal 1 or the like, and the workability when asking questions is improved.

  Similarly, in the present embodiment, as described above, the answer content of the respondent is presented to the questioner by the answer image data obtained by imaging the handwritten answer content, so that the answer information with only character information is insufficient or inappropriate. It is also possible to convey the correct answer contents to the questioner sufficiently or appropriately. In addition, the respondent can also give a reply by the work of writing the reply content by hand on a sheet at hand, capturing the reply with the camera unit 14 of the terminal 1, and transmitting the reply image data. Such an operation can be performed more easily and quickly than an operation for inputting text using the keyboard or the like of the respondent terminal 2, and the workability at the time of answering is improved.
