Description

  The present invention relates to a system for recording events that occur during a presentation by a computer.

Conventionally, presentation materials and events during a presentation are recorded in association with the presenter's video and audio so that they can be viewed repeatedly after the presentation. In particular, various efforts have been made centering on the method of detecting individual events that occur during a presentation and the mechanism of content for reproducing a recorded presentation.
For example, Patent Document 1 discloses a technique for creating a presentation file by associating sound during presentation, event information such as mouse cursor trajectory, page turning information with image data, and time code.
However, the conventional technology does not take into account when the event is recorded. In other words, in order to avoid operational failures during the presentation, and when special software and hardware used for the presentation are necessary, it is desirable to use the computer that the presenter himself uses regularly. Event recording is required only during the presentation, and recording of the presentation event during practice is unnecessary.
On the other hand, if the presenter activates software that records a presentation event at the start of the actual presentation, the presenter may forget to activate the software.
On the other hand, in order to prevent forgetting to start, if the event recording software for presentations is always started, unnecessary presentation events will be recorded. Work to identify the event is required.

[Processing in event recording software]
FIG. 4 is a diagram showing the configuration of the event recording software.
As shown in FIG. 4, the event recording software 101 executed on the PC 1 monitors the connection of the presentation software monitoring unit 101b that monitors the operation of the presentation software 100 to the PC 1 and the external display device in addition to the event recording unit 101a. The external display device connection monitoring unit 101c that performs, the system operator name acquisition unit 101d that acquires the operator name of the PC 1, the date and time acquisition unit 101e that acquires the date and time, and the schedule acquisition that acquires the schedule information of the presentation from the schedule information database of the server 2 The unit 101f is composed of a data transmission unit 101g which transmits a recorded event and presentation slide material to the server in association with video / audio.
The event management software 101 has a function of monitoring the presentation.
The presentation can be monitored by monitoring the operation of the presentation software 100 by the presentation software monitoring unit 101b and detecting that the slide show has started.

Further, when the projector 3 is connected to the notebook PC 1 by using an external display cable by the external display device connection monitoring unit, it may be automatically detected, and it may be determined that the presentation has been performed with the connection of the projector.
When these two monitoring functions are effective and either the start of the slide show in the presentation software 100 or the connection of the projector 3 is detected, the event recording software 101 determines whether or not to start recording the event during the presentation. Then, process.
The event recording software 101 can previously set a mode for instructing the operator whether or not to record an event and a mode for unconditionally recording when the start of the presentation is detected.
The event information recorded by the event recording software 101 records the event recording start date and time, the type of event that occurred, and the date and time when the event occurred. The latter may be an elapsed time from the event recording start date and time.

FIG. 5 is a flowchart for explaining the flow of processing in the event recording software.
As described above, the event recording software 101 is executed on the PC 1 to monitor the presentation (S100).
When the presentation software monitoring unit 101b does not detect the start of the presentation (start of the slide show) (No in S101), the external display device connection monitoring unit 101c monitors the presentation external display output (projector connection) (S102).
When the start of a slide show or an external display output is detected (Yes in S101 or Yes in S103), and a mode is set in which the operator himself instructs whether to start recording an event of a presentation (in S104) Yes) presents to the display device 11 a dialog as to whether or not to start recording a presentation event and a YES / NO button to the operator (S105).
If the button is selected using the mouse 12 and the keyboard 13 (S105), and YES is selected (Yes in S106), the event recording unit 101a starts recording a presentation event (S109).
If NO is selected (No in S106), the process returns to S100 and the monitoring process is repeated.

If the mode in which the operator instructs to start event recording is not set, the following processing is performed (No in S104). That is, if the mode for starting the recording of the presentation event unconditionally is set (Yes in S107), the recording of the presentation event is started (S109).
If neither a mode instructed by the operator nor a mode for unconditionally starting event recording is set (No in S107), an automatic determination process for determining whether or not to start recording a presentation event, which will be described later, is performed. (S108).
If the determination result is YES (Yes in S108), recording of the presentation event is started (S109). If the determination result is NO (No in S108), the process returns to S100 and the monitoring process is repeated.
In this way, the system operator is inquired whether to start recording the event during the presentation, triggered by the presentation (start of the slide show) or the output of the presentation to the external display device (connection of the external device). Recording is started according to the conditions, or it is automatically determined, and by recording the event in the presentation together with information corresponding to the date and time, the event of the presentation can be surely recorded without forgetting.

FIG. 6 is a diagram showing a dialog for allowing the operator to select whether or not to start recording a presentation event.
Next, in the processing of FIG. 5, neither the mode instructed by the operator nor the mode to start recording an event unconditionally is set in the event recording software 101, and it is automatically determined whether or not to start event recording. The processing of the event recording software when making a judgment will be described.
The event recording software 101 acquires the information of the system operator name (presenter name) by the system operator name acquisition unit 101d described above, acquires the date and time of determination by the date and time acquisition unit 101e, and schedule information of the server 2 It is automatically determined that the recording of the presentation event is started by comparing the information included in the individual schedule included in the schedule information recorded in advance in the database with the acquired system operator name and date.

FIG. 7 is a flowchart showing the flow of processing in the event recording software when it is automatically determined to start recording an event.
First, the event recording software 101 acquires the name of the operator who uses the PC 1 by the system operator name acquisition unit 101d (S200).
For example, an account logged in to the Windows (registered trademark) OS may be acquired, or a character string specifying a system operator name can be set in the event recording software itself, and the acquired character string is acquired. May be.
Next, the date and time at the time of determination is acquired by the date and time acquisition unit 101e (S201).
Next, the schedule acquisition unit 101 f acquires individual schedules one by one from the schedule information database of the server 2.
If there is an unacquired individual schedule (Yes in S203), an unacquired individual schedule is acquired from the schedule information (S204). If there is no unacquired individual schedule information (No in S203), presentation event recording is not started (S208), and the process returns to S100 in FIG.
Then, the event acquisition unit 101a determines whether the scheduled person name included in the acquired individual schedule information matches the system operator name (S205).
If they match (Yes in S205), it is determined whether the date and time at that time is between the scheduled start date and time and the scheduled end date and time in the individual schedule information. If so (Yes in S206), the recording of the presentation event is started. (S207).

The event acquisition unit 101a determines that the scheduled person name included in the acquired individual schedule information and the system operator name do not match (No in S205), and the date and time is not between the scheduled start date and time and the scheduled end date and time in the individual schedule information. (No in S206), does not start event recording (S208), and returns to S203 to check whether there is an unacquired individual schedule.
As described above, the event recording software has the function of acquiring the system operator name and the function of acquiring the date and time at that time, and the system operation is performed on the individual schedule included in the schedule information stored in the server 2. By comparing the name of the person and the date and time at that time, it is possible to appropriately and automatically determine whether or not to start recording the presentation event according to the schedule.
When the presentation ends, the data transfer unit 101g transmits the recorded event and the system operator name to the server.

[Processing in video recording software]
The video recording software has the function of automatically recording video and audio based on the schedule information recorded in the schedule information database, and the function of acquiring the date and time at that time. By comparing the date and time at that time, video / audio is automatically recorded based on the schedule information.
FIG. 8 is a diagram showing the configuration of the video recording software.
As shown in FIG. 8, the video recording software 200 controls the video camera 4 to record video and audio of a presentation, a video recording control unit 200a, a system operator name acquisition unit 200b, a date and time acquisition unit 200c, and schedule information acquisition. 200d.
FIG. 9 is a flowchart for explaining the flow of processing in the video recording software.
First, the date and time at that time is acquired by the date and time acquisition unit 200c (S301).
Next, the schedule information acquisition unit 200d acquires the schedule information of the presentation managed in the schedule information database 203.
First, when there is an unacquired individual schedule (Yes in S302), individual schedules are acquired one by one from the schedule information (S303), and the recording state included in the acquired schedule information is “before video recording”. If the current date and time acquired in S300 is after the scheduled start date and time (Yes in S305), the video recording control unit 200a starts video / audio recording on the video camera 4 (S306). ).

If the recording state of the presentation is not “before video recording” and the recording state of the presentation is video recording (Yes in S307), if the current date and time is after the scheduled end date and time (Yes in S308), The recording of video / audio is terminated (S309). In addition, when the recording state of the presentation is after video recording (No in S307), no processing is performed.
When the process is completed for the acquired individual schedule (S310), the process returns to S302 to further determine whether there is an unacquired individual schedule, and if not, the process ends.
As described above, the start / end date and time included in the schedule information and the date and time at that time are acquired and compared, so video and audio are automatically recorded at the appropriate date and time based on the schedule information. Can do.

[Processing of event / schedule association software]
Next, the server side performs processing for associating the slide material of the presentation and the video / audio recorded by the video recording software with the schedule information by the event / schedule association software.
Next, processing in the event / schedule association software will be described.
FIG. 10 is a diagram showing the configuration of the event / schedule association software.
As shown in FIG. 10, the event / schedule association software 202 includes an event / schedule association unit 202a that performs an actual association process, a data acquisition unit that performs a process of acquiring a system operator name, event information, and slide material from the terminal side. 202b includes a schedule acquisition unit 202c that acquires schedule information from the schedule management database.

FIG. 11 is a flowchart for explaining the flow of processing in the event / schedule association software.
First, the event / schedule association software 202 acquires the operator name transmitted from the PC 1 by the data acquisition unit 202b (S401).
Further, the data acquisition unit 202b acquires the date and time when the event was recorded from the event information transferred from the PC 1 (S402).
Next, the schedule acquisition unit 202c acquires individual schedules stored in the schedule information database 203 of the server 2 one by one.
If there is an unacquired individual schedule (Yes in S403), an unacquired individual schedule is acquired from the schedule information (S404). If there is no unacquired individual schedule, the process ends.
Then, it is determined whether the scheduled person name included in the acquired individual schedule information matches the system operator name transmitted from the PC 1 (S405).
If they match (Yes in S405), it is determined whether the recording date / time of the event acquired from the PC 1 is between the scheduled start date / time and the scheduled end date / time in the individual schedule information. If so (Yes in S406), the event schedule The associating unit 202 requests the data transfer unit 101g of the PC 1 to transfer the slide material used for the presentation, and when the slide material is transferred from the PC 1, it associates it with the presentation schedule (S407).

When the scheduled person name included in the acquired individual schedule information does not match the system operator name (No in S405), and when the date / time is not between the scheduled start date and time and the scheduled end date / time in the individual schedule information (No in S406). Returning to S403, it is checked whether there is an unacquired individual schedule.
In this way, the event / schedule association software 202 can associate the event being presented, slide material, and video / audio with the presentation schedule.
Also, by associating these, it is possible to acquire video / audio, slide material, and event information at the time of presentation from schedule information stored on the server.
