Description

The present invention relates to a conference system, a deletion method, and a program.

For example, there is a technology that electronically records the contents written on a handwriting board such as a whiteboard used in a meeting. Conventionally, there is known a technology that electronically captures the contents written on a whiteboard during a meeting, stores the captured data, and enables a user to retrieve the contents written on the whiteboard at any time during the meeting (see, for example, Patent Document 1).

Some conventional electronic whiteboards have a function that allows users to input strokes that disappear after a few seconds, in other words, strokes that are displayed temporarily. For example, a user who uses an electronic whiteboard in a meeting can input content that he or she does not want to save using strokes that are displayed temporarily.

However, strokes that are temporarily displayed cannot be kept displayed even if the user expects them to continue. For example, it would be convenient for a user who uses an electronic whiteboard in a meeting to be able to input strokes that are not to be saved and that are displayed until the end of the meeting. However, Patent Document 1 does not address this issue.

The objective of an embodiment of the present invention is to provide a conference system that continues to display strokes that are not to be saved.

In order to achieve the above-mentioned object, claim 1 of the present application provides a conference system having an electronic device that receives input of strokes and displays the strokes, and an information processing device that stores information on the strokes, the electronic device having a mode switching means that receives an operation to switch between a first mode that receives input of the strokes to be saved and a second mode that receives input of the strokes other than the strokes to be saved, an input receiving means that receives input of the strokes in the first mode or the second mode, a display control means that displays the strokes that have been input, and a transmission means that transmits information on the strokes that have been input in the first mode or the second mode to the information processing device in a state in which the strokes that have been input in the second mode can be identified, and the information processing device has a deletion means that deletes information on the strokes that have been input in the second mode before saving the information on the strokes.

According to an embodiment of the present invention, a conference system can be provided that continues to display strokes that are not to be saved.

The stroke information storage unit 54 stores a list of information on strokes to be saved after the information on strokes not to be saved has been deleted by the deletion unit 44.

<Screen image>
5 is a diagram showing an example of a screen image of the interactive whiteboard 10 according to the present embodiment. In the interactive whiteboard 10 according to the present embodiment, a user interface 1000 is displayed on the display 680. A user can select and use various functions of the interactive whiteboard from the user interface 1000.

The user interface 1000 includes a mode switching button 1002. The mode switching button 1002 accepts an operation from the user to switch between a first mode that accepts input of strokes to be saved and a second mode that accepts input of strokes other than those to be saved. In the following description, the first mode is referred to as the normal mode, and the second mode is referred to as the erase mode. Note that the operation to switch between the normal mode and the erase mode may be accepted from the user by, for example, operating a specific key on the keyboard or operating a specific button on the electronic pen 690.

For example, when the electronic whiteboard 10 receives input of a stroke to be saved from a user in normal mode, it displays a stroke 1004 in normal mode on the display 680, for example, as shown in FIG. 5. Also, when the electronic whiteboard 10 receives input of a stroke other than the stroke to be saved from a user in erase mode, it displays a stroke 1006 in erase mode on the display 680, for example, as shown in FIG. 5.

Figure 5 shows an example in which the display form of the normal mode stroke 1004 and the erase mode stroke 1006 are made different to make it easier to visually distinguish between the normal mode stroke 1004 and the erase mode stroke 1006. Note that the display form of the normal mode stroke 1004 and the erase mode stroke 1006 is made different by changing the transparency, for example. The display form of the normal mode stroke 1004 and the erase mode stroke 1006 may also be made different by changing the line type, for example, between a solid line and a dotted line. Note that the display form of the normal mode stroke 1004 and the erase mode stroke 1006 may be the same.

<Processing>
Fig. 6 is a sequence diagram showing an example of a processing procedure for strokes other than those to be saved in the conference system 1 according to the present embodiment. Fig. 6 shows an example of a process for deleting information on strokes other than those to be saved at a predetermined timing when input of strokes other than those to be saved is received from a user.

In step S10, the user performs an operation to change the mode from the normal mode to the erase mode, for example, using the mode switching button 1002 in FIG. 5. In step S12, the electronic whiteboard 10 changes the stroke input mode to the erase mode.

In step S14, the user performs an operation on the electronic whiteboard 10 to input the stroke 1006 in the erase mode. The electronic whiteboard 10 displays the stroke 1006 in the erase mode on the display 680, for example, as shown in FIG. 5.

In step S16, the electronic whiteboard 10 transmits information about the stroke 1006 input by the user in the erase mode to the information processing device 12 in the erase mode. In step S18, the information processing device 12 adds the received information about the stroke 1006, the input mode indicating the erase mode, and the time when the user input the stroke 1006 to the list held by the stroke list holding unit 52.

Note that FIG. 6 shows the process when the stroke 1006 in the erase mode is input once by the user. The stroke 1006 in the erase mode may be input by the user multiple times. FIG. 6 may also include the process when the stroke 1004 in the normal mode is input by the user. When the stroke 1004 in the normal mode is input by the user, the electronic whiteboard 10 transmits information about the stroke 1004 input by the user in the normal mode to the information processing device 12 in the normal mode. The information processing device 12 adds the received information about the stroke 1004, the input mode indicating the normal mode, and the time when the user input the stroke 1004 to the list held by the stroke list holding unit 52.

Steps S20 to S26 in FIG. 6 show the processing that occurs when a user performs a PDF save operation on the electronic whiteboard 10 to save the image displayed on the display 680 in PDF format.

In step S20, the user performs a PDF save operation on the electronic whiteboard 10. In step S22, the electronic whiteboard 10 notifies the information processing device 12 of the PDF save. In step S24, the information processing device 12 deletes the information of the strokes in erase mode from the list stored in the stroke list storage unit 52. When the information processing device 12 has completed the deletion of the information of the strokes in erase mode, it notifies the electronic whiteboard 10. The deletion of the information of the strokes in erase mode performed by the information processing device 12 is reflected in the image displayed on the display 680 of the electronic whiteboard 10. Note that the information of the strokes in normal mode is not deleted and continues to be displayed. In step S26, the electronic whiteboard 10 creates a PDF file of the image displayed on the display 680 and saves it.

In this way, in the conference system 1 according to this embodiment, it is possible to continue displaying strokes in erase mode until a PDF save operation is received from the user, and it is possible to create and save a PDF file after deleting the information about strokes in erase mode.

Steps S30 to S34 in FIG. 6 show the processing that is performed when it is determined that the meeting is to end. In step S30, the user operates the electronic whiteboard 10 to select the end of the meeting.

In step S32, the electronic whiteboard 10 notifies the information processing device 12 of information indicating the end of the meeting. In step S34, the information processing device 12 deletes the information of the stroke in the erase mode from the list stored in the stroke list storage unit 52.

In this way, in the conference system 1 according to this embodiment, the display of strokes in erase mode can be continued until it is determined that the conference has ended, and the stroke information can be stored in the stroke information storage unit 54 after the information of the strokes in erase mode has been deleted.

Steps S40 to S42 in FIG. 6 show the process when detecting information about a stroke in erase mode that has been input for a certain amount of time. In step S40, the information processing device 12 detects information about a stroke in erase mode that has been input for a certain amount of time from the list in the stroke list storage unit 52. In step S42, the information processing device 12 deletes the information about the stroke in erase mode from the list stored in the stroke list storage unit 52.

In this way, in the conference system 1 according to this embodiment, it is possible to continue displaying strokes in erase mode until a certain time has passed since they were input, and it is possible to delete information about strokes in erase mode that have been input for a certain time, and then store the information about the strokes in the stroke information storage unit 54.

Each function of the above-described embodiments can be realized by one or more processing circuits. In this specification, the term "processing circuit" includes a processor programmed to execute each function by software, such as a processor implemented by an electronic circuit, and devices such as an ASIC (Application Specific Integrated Circuit), DSP (digital signal processor), FPGA (field programmable gate array), and conventional circuit modules designed to execute each function described above.
