<Functional configuration of the electronic blackboard according to the first embodiment>
Next, the functional configuration of the electronic blackboard 2 will be described. FIG. 4 is a block diagram illustrating an example of the functional configuration of the electronic blackboard 2 according to the present embodiment. As shown in FIG. 4, the electronic blackboard 2 has a storage unit 20 and a control unit 21.

The storage unit 20 can input and store the information output by the storage control unit 25. Further, the storage unit 20 has a first recording unit 261 and a second recording unit 262. Whether the information input from the storage control unit 25 is recorded in the first recording unit 261 or the second recording unit 262 is controlled by the storage control unit 25 as described later. The first recording unit 261 can be realized by the RAM 203A or the like, and the second recording unit 262 can be realized by the RAM 203B or the like. Here, the first recording unit 261 and the second recording unit 262 are examples of "plurality of recording units".

The control unit 21 has an information input unit 22, an event detection unit 23, a time measurement unit 24, a storage control unit 25, and a transmission unit 26, and stores the minutes information of the meeting using the electronic blackboard 2. The electronic blackboard 2 can be controlled to be stored in the unit.

The information input unit 22 is realized by an external device connection I / F 206, an electronic pen controller 216, a contact sensor 214, etc., and can input the above-mentioned "input information" and output it to the event detection unit 23 and the storage control unit 25. it can.

The event detection unit 23 detects the occurrence of a predetermined event. Here, the predetermined event is an event used for estimating the period that is the main point of the meeting among the events performed on the electronic blackboard 2. The predetermined event includes an event that the PC 6 is connected to the electronic blackboard 2, an event that the user inputs (draws) with the electronic pen 290 or the user's hand H, or a predetermined keyword. Includes an event that the corresponding audio information has been entered.

It is highly possible that the time when the PC 6 is connected to the electronic blackboard 2 is the time when the user participating in the conference starts the presentation. And, such a presentation is related to the main agenda of the meeting, and the content of the presentation, the question and answer session for the presentation, the discussion, etc. are likely to be the main points of the meeting. Therefore, the period before and after the time when the PC 6 is connected is one of the periods in which the main point information of the conference can be obtained.

In addition, the time when the user inputs (draws) with the electronic pen 290 or the user's hand H is a period before and after that time, and the user explains more specific opinions using characters and figures. , There is a high possibility that the discussion will be summarized. Therefore, the period before and after the time when the input (drawing) by the electronic pen 290 or the user's hand H is performed is one of the periods in which the main point information of the conference can be obtained.

Furthermore, the wording included in the agenda of the meeting is defined in advance as a keyword, and the time when such a keyword is included in the voice collected by the microphone 240 is the period before and after that time, and the meeting There is a high possibility that discussions will be held directly on the agenda. Therefore, the period before and after the time when the voice information including the predetermined keyword is input is one of the periods in which the main point information of the meeting can be obtained.

Here, the keyword extraction unit 231 included in the event detection unit 23 has a function of extracting the above-mentioned keywords from the voice information input by the information input unit 22. As an example, if the agenda of the meeting is "project schedule", the word "delivery date" is likely to be important, so "delivery date" is set in advance as a keyword. The keyword extraction unit 231 extracts the "delivery date" of the keyword from the voice information input by the information input unit 22. The event detection unit 23 detects the occurrence of an event when the keyword “delivery date” is extracted by the keyword extraction unit 231.

In this way, the event detection unit 23 can detect the occurrence of a predetermined event and notify the time measurement unit 24 of the occurrence of the predetermined event.

The time measuring unit 24 includes a timer for measuring the time, measures the elapsed time from the occurrence of a predetermined event by using the time when the event detection unit 23 notifies the event as a trigger, and the elapsed time is predetermined. When the predetermined time Δt is reached, the storage control unit 25 is notified to that effect.

Further, the time measurement unit 24 also has a function of determining whether or not the timer is performing the time measurement operation and resetting the timer. The timer can measure the time by counting the clock of the CPU 201 or the like.

The storage control unit 25 causes at least one of the first recording unit 261 and the second recording unit 262 to record the input information by the information input unit 22. Further, the storage control unit 25 is input in a predetermined period of the input information recorded in at least one of the first recording unit 261 and the second recording unit 262 in response to the occurrence of the predetermined event described above. The input information is stored in the storage unit provided in the server 5. Further, the storage control unit 25 can have the other recording units of the first recording unit 261 and the second recording unit 262 record the input information input during the predetermined period.

As a more specific example, the storage control unit 25 causes the first recording unit 261 to record the input information by the information input unit 22. Then, after the event detection unit 23 detects the occurrence of a predetermined event, when the time measurement unit 24 notifies that the predetermined time Δt has elapsed, the storage control unit 25 sends the input information to the first recording unit 261. Of the input information recorded in the first recording unit 261, the process of cutting out the input information input in a predetermined period is executed. Such a cutting process can be executed by the information cutting unit 251 included in the storage control unit 25.

More specifically, the information cutting unit 251 refers to the first recording unit 261 and has a predetermined time Δt with respect to the time notified from the time measuring unit 24 among the input information recorded in the first recording unit 261. The input information of the period from the time two times before to the time when the notification is received from the time measurement unit 24 is cut out.

In other words, the information cutting unit 251 cuts the input information in the period of the predetermined time Δt before and after the time when the predetermined event occurs. As described above, the period before and after the time when a predetermined event occurs is the period during which the main point information of the meeting can be obtained. Therefore, by cutting out the input information in this period, the main point information of the meeting can be obtained. it can. Then, the storage control unit 25 transmits the input information cut by the information cutting unit 251 to the server 5 via the transmitting unit 26, and stores the input information in the storage unit 52 provided in the server 5. The predetermined time Δt is set in advance by the user (meeting organizer, participants, etc.) and stored in SSD 204 or the like with an appropriate length of time according to the agenda of the meeting or the like.

Here, if the electronic blackboard system as a comparative example has only one recording unit, the input information for a predetermined period is cut out from the input information recorded in one recording unit and stored in the storage unit. During that time, the input information by the information input unit 22 cannot be recorded. Therefore, the input information during this period cannot be stored in the storage unit 52.

On the other hand, in the present embodiment, the storage control unit 25 cuts out the input information for a predetermined period from the input information recorded in the first recording unit 261 and inputs the information while storing it in the storage unit 52. The input information by the unit 22 is recorded in the second recording unit 262. As a result, the period during which the input information cannot be recorded can be eliminated, and the input information can be continuously recorded in at least one of the plurality of recording units.

The transmission unit 26 is realized by the network I / F205 or the like, and has a function of transmitting the input information cut by the information cutting unit 251 to the server 5 via the communication network 9.

Next, FIG. 5 is a block diagram illustrating an example of the functional configuration of the server 5 according to the present embodiment. As shown in FIG. 5, the server 5 has a receiving unit 51 and a storage unit 52.

The receiving unit 51 is realized by the network I / F 509 or the like, receives the input information cut by the information cutting unit 251 from the transmitting unit 26 of the electronic blackboard 2 via the communication network 9, and outputs it to the storage unit 52. ..

The storage unit 52 is realized by the HDD 504 or the like, and can input and store the input information cut by the information cutting unit 251 from the receiving unit 51. The input information that is the main point of the meeting cut out by the information cutting unit 251 is stored in the storage unit 52 as the minutes information.

<Operation of the electronic blackboard according to the first embodiment>
Next, the operation of the electronic blackboard 2 will be described. FIG. 6 is a flowchart showing an example of the operation of the electronic blackboard 2 according to the present embodiment.

First, in step S61, the storage control unit 25 causes the first recording unit 261 to start recording the input information by the information input unit 22.

Subsequently, in step S62, the event detection unit 23 determines whether or not an external input device such as a PC 6 is connected to the electronic blackboard 2.

If it is determined in step S62 that the external input device is connected (step S62, Yes), the event detection unit 23 notifies the time measurement unit 24 to that effect, and proceeds to step S65. On the other hand, if it is determined that the external input device is not connected (step S62, No), the process proceeds to step S63, and the event detection unit 23 determines whether or not the input has been made by the electronic pen 290 or the like.

If it is determined in step S63 that the input has been made by the electronic pen 290 or the like (step S63, Yes), the event detection unit 23 notifies the time measurement unit 24 to that effect, and proceeds to step S65. On the other hand, if it is determined that the input by the electronic pen 290 or the like has not been performed (step S63, No), the process proceeds to step S64, and the event detection unit 23 determines whether or not the input information includes the voice of the keyword. judge.

If it is determined in step S64 that the voice of the keyword is included (step S64, Yes), the event detection unit 23 notifies the time measurement unit 24 to that effect, and proceeds to step S65. On the other hand, if it is determined that the voice of the keyword is not included (step S64, No), the process returns to step S62, and the operations after step S62 are performed again.

In other words, the operations of steps S62 to S64 are operations in which the event detection unit 23 detects whether or not a predetermined event has occurred, and when a predetermined event occurs, the event detection unit 23 measures the time to that effect. Notify department 24. The order of the operations of steps S62 to S64 can be changed as appropriate, and the operations of steps S62 to S64 may be executed in parallel.

Subsequently, in step S65, the time measuring unit 24 determines whether or not the timer is running. If it is determined in step S65 that the timer is not running (step S65, No), the process proceeds to step S67. On the other hand, if it is determined that the timer is running (step S65, Yes), the time measuring unit 24 resets the timer in step S66.

Subsequently, in step S67, the time measurement unit 24 starts the timer and starts the time measurement. In other words, the time measuring unit 24 starts measuring the elapsed time after the occurrence of a predetermined event.

Subsequently, in step S68, the time measuring unit 24 compares the elapsed time with the predetermined predetermined time Δt, and determines whether or not the predetermined time Δt has elapsed after the occurrence of the predetermined event.

If it is determined in step S68 that the predetermined time Δt has elapsed (step S68, Yes), the time measuring unit 24 notifies the storage control unit 25 to that effect, and proceeds to step S69. On the other hand, if it is determined that the process has not elapsed (step S68, No), the operation of step S68 is repeated.

Subsequently, in step S69, the storage control unit 25 causes the first recording unit 261 to stop recording the input information.

Subsequently, in step S70, the storage control unit 25 causes the second recording unit 262 to start recording the input information.

Subsequently, in step S71, the information cutting unit 251 starts from a time that is twice as long as the predetermined time Δt with respect to the time notified by the time measuring unit 24 among the information recorded by the first recording unit 261. The input information for the period up to the time when the notification is received from the time measurement unit 24 is cut out. In other words, the information cutting unit 251 cuts the input information in the period of the predetermined time Δt before and after the time when the predetermined event occurs. Then, the information cutting unit 251 outputs the cut input information to the transmitting unit 26.

Subsequently, in step S72, the transmission unit 26 transmits the input information cut by the information cutting unit 251 to the server 5 via the communication network 9. The receiving unit 51 of the server 5 outputs the input information cut by the information cutting unit 251 to the storage unit 52, and the storage unit 52 stores this.

In this way, the electronic blackboard 2 can acquire the information that becomes the main point of the meeting and store it in the storage unit 52 as the minutes information.

Here, FIGS. 7 to 9 are diagrams for explaining an example of the minutes information stored in the electronic blackboard system according to the present embodiment. 7 to 9 show the minutes information when the user accesses the minutes information stored in the storage unit 52 by using the PC 4 connected to the communication network 9 and displays the minutes information on the screen of the monitor provided in the PC 4.
