Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telewriting device for exchanging handwritten images while talking with a communication partner.

[0002]

2. Description of the Related Art A telewriting device for exchanging handwritten images while talking with a communication partner is known. In such a telewriting device, two people communicate with each other 1:
Not only one communication but also N: N communication in which a plurality of people communicate at the same time is possible. Therefore, it is also used as a part of a video conference system.

By the way, in the case of a conference by N: N communication, each participant arbitrarily speaks. In this case, in order for the conversation to proceed smoothly, all the participants need to know the name, affiliation, and post of the speaker at that time.

However, in the conventional telewriting device, it has been difficult to judge who the speaker is from the voice of the speaker. In addition, even if the name of the speaker is known, the affiliation or post of the person may not be known because he does not know it.

Incidentally, for example, JP-A-59-221092
As can be seen in the publication, it has been proposed that during a communication conference, information about which microphone is transmitting is transmitted to the communication partner, and the identification information of the speaker is displayed on the screen at the communication partner. . However, this proposal is not applicable to a telewriting device because it transmits the above information together with a video signal to display the identification information on a television screen. In addition, it is impossible to display specific information such as the name of the speaker.

[0006]

As described above, in the conventional telewriting device, when a plurality of people communicate, information about the speaker such as the speaker's name, affiliation, or job title can be easily read by another person. There was a problem that I could not know.

It is an object of the present invention to solve the above problems and to provide a telewriting device which allows other persons to easily know information about a speaker when a plurality of people communicate with each other.

[0008]

To this end, according to one invention of the present application, information relating to a user of each device is stored in advance for each device, and when a call voice is transmitted to another device,
When the identification information of the own device is transmitted and the identification information is received from another device, the information about the corresponding user is displayed on the screen.

Another aspect of the present invention is that the characteristics of the utterance sound of the user of each device and the information about the user are stored in advance, and when a call voice is received from another device,
The feature of the utterance sound of the call voice is analyzed, and the information about the user corresponding to the feature of the utterance sound is displayed on the screen.

[0010]

As a result, by previously storing the user's name, affiliation, job title, etc., the above information of the speaker is displayed on each device during communication, so that other people can easily know it. become able to.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a system configuration diagram of a telewriting communication system according to an embodiment of the present invention. This system includes multiple telewriting devices 1
And one multipoint control unit 2 are connected to the ISDN network.

FIG. 2 is a block diagram of the telewriting device 1. In the figure, the screen display device 101 is a liquid crystal display device or the like for displaying an image. An operator touches the touch panel 102 with a touch pen 103.
Then, by tracing on the panel, characters and images are input by handwriting. The scanner 104 reads a document image. The image processing unit 105 executes control for inputting and displaying an image, data compression of image information, decompression processing of compressed data, and the like. The image memory 106 stores image information.

The microphone 107 is for inputting the transmitted voice, and the speaker 108 is for outputting the received voice.
The transmission detection unit 109 detects the start of transmission. The voice processing unit 110 transmits the voice signal by
Mutual conversion between an analog signal and a digital signal, data compression of digital information, and restoration processing of compressed data are executed.

The communication unit 111 is for transmitting and receiving image information and audio information which are data-compressed. System memory 11
2 stores information to be registered in advance, or temporarily stores various information during communication operation. Control unit 113
Is a microcomputer for monitoring and controlling each of the above parts.

With the above configuration, the telewriting communication system of the present embodiment has a function in which a plurality of users use the telewriting devices 1 one by one and hold a communication conference while viewing the same document image. It's

When such a communication conference is held, any one of the telewriting devices 1 performs preprocessing before the conference is held. This preprocessing is executed by, for example, one of the users who organizes the conference.

When executing the pre-processing, the user is
As shown in FIG. 3, the telewriting device 1 creates a document to be used in a conference. This document is processed by the image processing unit 105.
It is created by reading a document with or by inputting by handwriting on the touch panel 102 (process 1001). The created document is stored in the image memory 106 (process 1002).

Next, the ISDN number of each telewriting device 1 for which a conference is to be held and information regarding the user are input. The information about the user is, for example, the user's name, affiliation, and post. Such user information is sequentially input (process 1003).

The telewriting device 1 stores the input information as user correspondence information in the system memory 112 as shown in FIG. 4 (process 100).
4).

After that, by a predetermined operation, it is transmitted to each telewriting device 1 which holds the conference, and the created document image and the user correspondence information are transmitted (process 100).
5).

In this case, the receiving side stores the received document image in the image memory 106 and stores the user correspondence information in the system memory 112 as in the transmitting side.

Next, when a communication conference is to be held, as shown in FIG. 5, any one of the telewriting devices 1 calls the multipoint control device 2. Then, an N: N communication link for communicating with a plurality of other telewriting devices 1 via the multipoint control device 2 is formed according to a known procedure (process 2001). After that, the telewriting device 1 starts a predetermined telelighting communication (process 2).
002).

As a result, the transmitted voice input by any one of the telewriting devices 1 is transmitted to all the other telewriting devices 1 and the speaker 10 of each device is transmitted.
It is output from 8. An image input on one touch panel 102 is displayed on the screen display 101 of each of the other devices. This allows a plurality of users to exchange images while talking to each other.

During this operation, each telewriting device 1
Monitors the transmission of its own device (process 2003). The transmission is monitored by the transmission detecting unit 109. For example, when the voice signal obtained from the microphone 107 reaches a certain level or higher, it is determined that the transmission has started.

When the start of transmission is detected in this way (Y in process 2003), the ISDN number of the own device is transmitted to all the other telewriting devices 1 (process 2004).
As this transmission method, for example, it is conceivable to newly define a dedicated transmission frame in addition to the transmission frame of audio information or image information, or to transmit by a user / user signal on the D channel.

After this transmission, the same monitoring operation is returned to (process 2003). Then, when no call is transmitted (Processing 2)
003 N), ISD from other telewriting devices 1
It is monitored whether the N number is transmitted (process 200).
5). If the ISDN number is not sent (procedure 20)
(N in 05), it is determined whether or not there is an instruction to end communication (process 2006). If communication is not ended (N in process 2006), the same monitoring is continued (to process 2003).

Then, when the ISDN number is transmitted from the other telewriting device 1 (Y in process 2005), the ISDN number is received and the corresponding user information in the system memory 112 is displayed on the screen display 101. (Process 2007). Then, the process returns to the monitoring operation (process 200).
3).

As a result, when a user speaks on any one of the telewriting devices 1, the information such as the name, affiliation, and post of the speaker is displayed on each of the other telewriting devices 1 each time. Like

When ending the communication conference, each user performs a predetermined communication end operation. When the operation is performed (Y in process 2006), the telewriting device 1 disconnects the communication link and ends the telewriting communication (process 2008).

As described above, in this embodiment, each telewriting device 1 is connected to the ISDN of another device before the communication conference.
The number and the user information are stored, and the ISDN number of the own device is transmitted to another device at the time of transmission during the communication conference,
When the ISDN number is received from another device, the corresponding user information is displayed on the screen.

As a result, when the user speaks during the communication conference, the corresponding user information is displayed on each of the other telewriting devices 1, so that the other users can easily know the speaker. become.

In the above embodiment, the ISDN number is transmitted from the telewriting device 1 that is speaking to each of the other devices, but the user information itself may be transmitted. In addition, in order to reduce transmission information, ISDN
Instead of the number, other identification information for identifying each device may be defined and transmitted.

Next, a second embodiment of the present invention will be described.

FIG. 6 shows a part of the telewriting device 1 of this embodiment. Other parts not shown have the same configuration as in FIG. That is, in this embodiment, the transmission detection unit 109 of FIG. 1 is removed, and the voiceprint analysis unit 114 and the reception detection unit 115 are newly provided. The voiceprint analysis unit 114
This is to determine what is called a voiceprint, which is a feature of a user's vocal sound. The reception detection unit 115 detects a reception from a communication partner.

With this configuration, when conducting a communication conference,
In advance, documents are stored in all the telewriting devices 1 and user correspondence information is stored in the procedure shown in FIG.

When carrying out a communication conference, as shown in FIG. 7, each user first causes the telewriting device 1 to store his or her own voiceprint. In this process, for example, the user utters a specific word, the uttered sound is analyzed by the voiceprint analysis unit 114, and the obtained voiceprint information is stored (process 3001).

Thereafter, a predetermined N: N communication link is formed between the telewriting devices 1 (process 3002).
Next, each telewriting device 1 transmits its own ISDN number and the voiceprint information of the user to the other telewriting device 1. In addition, the information transmitted from each of the other devices is received and stored. In this way, the voiceprint information is exchanged between the devices (process 3003).

After this, telewriting communication is started (process 3004). The telewriting device 1 monitors the reception during this communication (process 3005). This monitoring is
This is executed by the reception detection unit 115, and the reception detection unit 1
For example, 15 determines that the received voice signal is received when the received voice signal exceeds a certain level.

When the reception is detected in this way (Y in process 3005), the voiceprint of the voice signal is analyzed by the voiceprint analysis unit 11.
Analyze according to 4. In addition, when a plurality of users simultaneously speak, the voiceprint of each person is analyzed. Then, the analysis result and the stored voiceprint information are collated to determine the ISDN number of the other party (process 3006). Then, the user information corresponding to the determined ISDN number is displayed (process 3007).

After that, the process returns to the above monitoring (process 3005).
What). If the call is not received (N in process 3005), it is determined whether the communication has ended (process 300).
8) If the communication is not completed (N in process 3008), the monitoring operation is continued (to process 3005). When the operator performs a communication end operation (Y in process 3008), the communication link is disconnected and the communication ends (process 30).
09).

As described above, in this embodiment, before the communication conference, the telewriting device 1 stores the user information of each of the other devices and the voiceprint information of the user, and the communication conference is performed. In this case, the voiceprint is analyzed from the received voice signal and the corresponding user information is displayed.

As a result, similarly to the above-described embodiment, when a user speaks during a communication conference, the user information is displayed on each device, so that other users can easily know the speaker. it can.

Further, in the present embodiment, each telewriting device 1 determines the speaker based on the received audio signal. Thus, it becomes unnecessary to transmit the device identification information such as the ISDN number.

Even if a plurality of users speak at the same time during the communication conference, the voiceprint of each person is discriminated and the respective user information is displayed, so that the speaker can be known at any time. .

In each of the above embodiments, only the user information of the speaker is displayed, but it may be displayed, for example, as shown in FIG. That is, during a communication conference, the operator's display request is monitored (N loop of process 4001), and if a display request is made (Y of process 4001), a list of stored ISDN numbers and user information is displayed. The screen is displayed (process 4002). In general, members who have never talked with each other rarely hold a teleconference, and thus it is also useful to simply display a list of members' names, affiliations, positions, etc.

Further, in each of the above-mentioned embodiments, the user correspondence information is input by one telewriting device and the information is transferred to another telewriting device.
The same information may be input to each telewriting device.
