In addition, after making the material inaccessible, if the unauthorized person is no longer detected, the material is displayed again and changed to a state in which it can be viewed. A person who is not permitted to view the document is an example of a person who does not have the authority to view the document.

[Functional configuration of electronic conference system]
FIG. 3 is a block diagram showing a functional configuration example of each device constituting the electronic conference system according to the present embodiment. As shown in the figure, the electronic conference system in the present embodiment includes a master terminal 10, a slave terminal 30, and a server 50. As described above, there may be two or more slave terminals 30, but only one is shown here.

First, a functional configuration example of the master terminal 10 will be described. As shown in the figure, the master terminal 10 includes a transmission unit 21, a reception unit 22, an operation reception unit 23, and a display control unit 24.

When starting the conference, the transmission unit 21 transmits the conference start information indicating that the conference is to be started to the server 50. Further, when displaying the material on the master terminal 10, the material ID is transmitted to the server 50.

When displaying the material on the master terminal 10, the receiving unit 22 receives the material from the server 50. Further, when the approach of a person who is not permitted to browse is detected, the server 50 receives the non-display instruction information instructing to hide the displayed material. Further, when the separation (moving away) of the person who is not permitted to browse is detected, the server 50 receives the non-display release instruction information instructing to cancel the non-display state of the material.

When starting a meeting, the operation reception unit 23 receives an operation for starting the meeting. Further, when displaying the material on the master terminal 10, the operation of inputting the material ID is accepted.

When displaying the material on the master terminal 10, the display control unit 24 controls the display device 15 so as to display the material. Further, when the approach of a person who is not permitted to browse is detected, the display device 15 is controlled so as to hide the material being displayed. For example, when the material is displayed as an image in JPEG format or the like by a web browser, it may be hidden by displaying a blank image. Further, when the separation of the person who is not permitted to browse is detected, the display device 15 is controlled so as to cancel the non-display state of the material.

Next, a functional configuration example of the slave terminal 30 will be described. As shown in the figure, the slave terminal 30 includes a transmission unit 41, a reception unit 42, an operation reception unit 43, and a display control unit 44.

The transmission unit 41 does not particularly function when the display state of the material is changed due to the approach or distance of a person who is not permitted to browse, but transmits operation information indicating various operations in other situations to the server 50.

When displaying the material on the slave terminal 30, the receiving unit 42 receives the material from the server 50. Further, when the approach of a person who is not permitted to browse is detected, the server 50 receives the non-display instruction information instructing to hide the displayed material. Further, when the separation (moving away) of the person who is not permitted to browse is detected, the server 50 receives the non-display release instruction information instructing to cancel the non-display state of the material.

The operation reception unit 43 does not particularly function when changing the display state of the material due to the approach or distance of a person who is not permitted to browse, but accepts various operations in other situations.

When displaying the material on the slave terminal 30, the display control unit 44 controls the display device 35 so as to display the material. Further, when the approach of a person who is not permitted to browse is detected, the display device 35 is controlled so as to hide the material being displayed. For example, when the material is displayed as an image in JPEG format or the like by a web browser, it may be hidden by displaying a blank image. Further, when the separation of the person who is not permitted to browse is detected, the display device 35 is controlled so as to cancel the non-display state of the material.

Next, a functional configuration example of the server 50 will be described. As shown in the figure, the server 50 includes a transmission unit 61, a reception unit 62, a material storage unit 65, a material management unit 66, a conference management unit 67, an approach detection unit 68, and a distance detection unit 69. Be prepared.

The transmission unit 61 transmits the material to the master terminal 10 when displaying the material on the master terminal 10, and also transmits the material to the slave terminal 30 when displaying the material on the slave terminal 30. Further, when the approach of a person who is not permitted to browse is detected, the non-display instruction information instructing to hide the displayed material is transmitted to the master terminal 10 and the slave terminal 30. Further, when the separation of the person who is not permitted to browse is detected, the non-display release instruction information instructing to cancel the non-display state of the material is transmitted to the master terminal 10 and the slave terminal 30. In the present embodiment, as an example of the display control means for controlling the display device or the display means so as to display the document, and as a non-display control means for controlling the display device or the display means so as to hide the document. As an example, a transmission unit 61 is provided.

When starting the conference, the receiving unit 62 receives the conference start information indicating that the conference is to be started from the master terminal 10. Further, when displaying the material on the master terminal 10, the material ID is received from the master terminal 10.

The material storage unit 65 stores the material registered in the server 50.

When displaying the material on the master terminal 10, the material management unit 66 acquires the material identified by the material ID received from the receiving unit 62 from the material storage unit 65.

When the meeting is started, the meeting management unit 67 stores the state of being in a meeting (hereinafter, referred to as “in-meeting state”). Further, in response to the inquiry from the approach detection unit 68, it returns whether or not the in-meeting state is stored, that is, whether or not the meeting has started.

When the approach detection unit 68 inquires of the conference management unit 67 and returns a response that the conference has started, the approach detection unit 68 detects a person approaching the master terminal 10 or the slave terminal 30 as a viewing disallowed person. For example, if a physical sensor is installed in a conference room, this is connected to the server 50 via a communication line, and the physical sensor notifies that a person who has entered the conference room has been detected after the start of the conference, that person cannot be viewed. As an authorized person, the approach may be detected. In addition, when an access point near the conference room is connected to the server 50 via a communication line and the access point notifies that a radio wave having a strength equal to or higher than the threshold value has been received from the notebook PC or the like after the start of the conference, the notebook PC or the like is used. The approach may be detected by regarding the owner as a person who is not permitted to browse. Alternatively, if there is a person who has logged in to the electronic conference system after the start of the conference, that person may be regarded as an unauthorized person to view and the approach may be detected. This is based on the assumption that a person who intends to enter the conference room after the start of the conference may log in to the electronic conference system from a notebook PC or the like on the way to the conference room, for example. Further, the approach detection unit 68 shall pass the information of the viewing disallowed person who has detected that the person is approaching to the distance detection unit 69.

The distance detection unit 69 detects that a person who is not permitted to browse has moved away from (away from) the master terminal 10 or the slave terminal 30. For example, when the physical sensor notifies that the person who is not permitted to browse has left the conference room, which is detected by the approach detection unit 68, the distance of the person who is not allowed to browse may be detected. In addition, when the access point notifies that the access point has received a radio wave having a strength equal to or lower than the threshold value from a notebook PC or the like owned by the browsing disallowed person detected by the approach detection unit 68, the separation of the browsing disallowed person is detected. You may. Alternatively, when the viewing disallowed person detected by the approach detection unit 68 logs out from the electronic conference system, the separation of the viewing disallowed person may be detected.

[Operation of electronic conference system]
FIG. 4 is a sequence diagram showing an operation example when starting a conference of the electronic conference system according to the present embodiment and displaying materials.

As shown in the figure, in the master terminal 10, when the master performs an operation to start a conference, the operation reception unit 23 accepts this operation (step 101). Then, the transmission unit 21 transmits the conference start information indicating that the conference is to be started to the server 50 (step 102).

Then, in the server 50, the receiving unit 62 receives the conference start information from the master terminal 10 (step 501). Then, the conference management unit 67 stores the state during the conference (step 502).

After that, in the master terminal 10, when the master performs an operation of selecting the material ID, the operation receiving unit 23 accepts this operation (step 103). At this time, the operation of selecting the material ID may be performed, for example, by specifying the material ID on the list including the material ID displayed on the master terminal 10. Then, the transmission unit 21 transmits the selected material ID to the server 50 (step 104).

Then, in the server 50, the receiving unit 62 receives the material ID from the master terminal 10 (step 503). Then, the material management unit 66 acquires the material corresponding to the material ID from the material storage unit 65 (step 504). After that, the transmission unit 61 transmits the material to the master terminal 10 and the slave terminal 30 (step 505).

As a result, in the master terminal 10, the receiving unit 22 receives the material (step 105). Then, the display control unit 24 controls the display device 15 so as to display the material (step 106).

Further, in the slave terminal 30, the receiving unit 42 receives the material (step 301). Then, the display control unit 44 controls the display device 35 so as to display the material (step 302).

FIG. 5 is a sequence diagram showing an operation example when the approach or distance of a person who is not permitted to view the electronic conference system in the present embodiment is detected and the material is hidden or displayed.

As shown in the figure, in the server 50, the approach detection unit 68 detects the approach of the unauthorized person to the master terminal 10 or the slave terminal 30 (step 521). For example, when a new terminal is connected to the server 50, if the conference management unit 67 is inquired and a response indicating that the conference has started is returned, the owner of the terminal is detected as a viewing disallowed person. Then, the transmission unit 61 transmits the non-display instruction information instructing to hide the displayed material to the master terminal 10 and the slave terminal 30 (step 522).

As a result, in the master terminal 10, the receiving unit 22 receives the non-display instruction information from the server 50 (step 121). Then, the display control unit 24 controls the display device 15 so as to hide the displayed material (step 122).

Further, in the slave terminal 30, the receiving unit 42 receives the non-display instruction information from the server 50 (step 321). Then, the display control unit 44 controls the display device 35 so as to hide the displayed material (step 322).

On the other hand, in the server 50, the distance detection unit 69 detects the distance from the master terminal 10 or the slave terminal 30 of the person who is not permitted to browse (step 523). Then, the transmission unit 61 transmits the non-display release instruction information instructing to cancel the non-display state of the material to the master terminal 10 and the slave terminal 30 (step 524).

As a result, in the master terminal 10, the receiving unit 22 receives the non-display release instruction information from the server 50 (step 123). Then, the display control unit 24 controls the display device 15 so as to cancel the non-display state of the material (step 124).

Further, in the slave terminal 30, the receiving unit 42 receives the non-display release instruction information from the server 50 (step 323). Then, the display control unit 44 controls the display device 35 so as to cancel the non-display state of the material (step 324).

In this operation example, a person who entered the conference room after the start of the conference or a person who logged in to the system is detected as a person who is not permitted to browse without exception, but this is not the case. A person to be excluded from the target to be detected as a person who is not permitted to browse may be registered in advance, and control may be performed so that the material is not hidden when the person is detected. This is to prevent the materials from being hidden more than necessary when the participants enter and leave the room during the meeting.

By the way, in the present embodiment, when it is detected that there is a person who has entered the conference room after the start of the conference or there is a person who has logged in to the system after the start of the conference, the displayed material is hidden. However, this is not the case. When it is detected that another event indicating that the master terminal 10 or the slave terminal 30 is approaching has occurred, the displayed material may be hidden. In this sense, the fact that some people have entered the meeting room after the start of the meeting or that some people have logged in to the system after the start of the meeting means that a person who does not have the authority to view the document is approaching the display device. This is an example of a predetermined event shown. The conference room is an example of a space in which a display device exists.

Alternatively, instead of a person who does not have the authority to view the document approaching the display device, an attempt by a person who does not have the authority to view the document to display the document is used as a predetermined event. May be good. In this case, when it is detected that a person who does not have the authority to view the document tries to display the document, the displayed document is hidden. For example, when user D enters the same chat while three users A, B, and C are chatting, it is conceivable to temporarily hide the chat history so far. Furthermore, when it is detected that another event has occurred in a person who does not have the authority to view the document, the displayed material may be hidden. In this sense, if a person who does not have the authority to view the document is approaching the display device or a person who does not have the authority to view the document tries to display the document, he / she has the authority to view the document. This is an example of a predetermined event in a person who does not.

Further, in the present embodiment, when it is detected that a person who is not permitted to browse has left the conference room or logged out of the system, the hidden material is displayed again, but this is limited to this. is not it. When it is detected that another event indicating that the user has moved away from the master terminal 10 or the slave terminal 30 has occurred, the hidden material may be displayed again. In this sense, the fact that an unauthorized person leaves the conference room or logs out of the system is a predetermined event indicating that a person who does not have the authority to view the document has left the display device. This is an example.

Further, in the present embodiment, the slave terminal 30 has been mainly described as one, but a configuration in which the material is shared and displayed by a plurality of slave terminals 30 is also conceivable. In such a configuration, when the occurrence of an event is detected, all the slave terminals 30 may hide the material. Alternatively, the material may be hidden on the master terminal 10 and all the slave terminals 30. Then, after the material is hidden, if an instruction to allow the display of the document is input by either the master terminal 10 or the plurality of slave terminals 30, the hidden state is canceled and the material is displayed. May be displayed again.

Further, in the present embodiment, after the conference room can be entered even after the start of the conference, when a person who has entered the conference room is detected, the material displayed on the master terminal 10 or the slave terminal 30 is hidden. I made it into a state, but this is not the case. After the meeting starts, you may not be able to enter the meeting room. For example, it is conceivable to provide an entry / exit management system using an ID card, cooperate with an electronic conference system, and perform control such as prohibiting entry with the entry / exit management system after the start of the conference.

Further, in the present embodiment, after enabling login to the system even after the start of the conference, when a person who has logged in to the system is detected, the material displayed on the master terminal 10 or the slave terminal 30 is hidden. However, this is not the case. You may not be able to log in to the system after the meeting has started.

Further, in the present embodiment, the case where the present invention is applied to the electronic conference system has been described, but the present invention may be applied to a system other than the electronic conference system. As a system other than the electronic conference system, for example, a lecture system in a school or the like can be considered. In such a system, the master is the teacher and the slave is the student. Further, in such a system, the object for controlling display and non-display may be not a material but a teaching material. Alternatively, assuming a system other than the electronic conference system in general, the object for controlling display and non-display may be a document. Here, as mentioned above, the document also includes historical information such as characters indicating the result of communication such as chat performed between a plurality of display devices via input of characters and the like. do.

Furthermore, in the present embodiment, the server 50 is provided with a function of detecting the approach or separation of a person who is not permitted to view and controlling the display and non-display of the document, but the present invention is not limited to this. For example, the master terminal 10 may have such a function. In that case, the master terminal 10 is an example of the document display control device. A display control unit 24 is provided as an example of the display control means and the non-display control means when the display device 15 is an example of the display device or the display means, and the display device 35 is an example of the display device or the display means. As an example of the display control means and the non-display control means at a certain time, the transmission unit 21 is provided. Alternatively, the slave terminal 30 may have such a function. In that case, the slave terminal 30 is an example of the document display control device. A display control unit 44 is provided as an example of the display control means and the non-display control means when the display device 35 is an example of the display device or the display means, and the display device 15 is an example of the display device or the display means. As an example of the display control means and the non-display control means at a certain time, the transmission unit 41 is provided.
