In the system of FIG. 1, the site 1 and the site 2 conduct a video conference by using the

video conference devices

112 and 122. At this time, all members participating in the video conference wear name tag type portable electronic terminals of the same type as the name tag type portable

electronic terminals

113, 114, 123, and 124. Each of these name tag type portable

electronic terminals

113, 114, 123, and 124---has a unique identifier (ID), and it is possible to detect who and who are facing each other by transmitting and receiving this ID by infrared rays. I can do it. In addition, each of the

infrared transmitters

111 and 121 transmits a unique ID, and when the ID of the

infrared transmitters

mobile terminals

113, 114, 123, and 124---, which participant Can see if they are participating in a video conference at specific locations such as Site 1 and Site 2.

The name tag type portable

infrared transmitters

111 and 121, but each have a unique ID and perform communication using infrared rays. As a result, the face-to-face contact between members wearing name tag type portable

In addition, the name tag type mobile

electronic terminals

113, 114, 123, and 124--を-are equipped with illuminance sensors, acceleration sensors, temperature sensors, and microphones to acquire and collect data, so that the movement of members during the meeting, the amount of speech, etc. From this it is possible to measure the activity of the conference. As for the specific configuration of the name tag type portable electronic terminal, FIG. 2A showing the name tag type sensor node of Patent Document 3 previously filed by the present applicant, Japanese Patent Application Laid-Open No. 2008-129684, also filed by the present applicant, and the like. Is disclosed.

That is, although not shown, in the name tag type portable electronic terminal, predetermined processing is performed on the output of the built-in microphone, and various data are acquired from sensors such as an illuminance sensor, an acceleration sensor, and a temperature sensor. The built-in infrared transmitter / receiver performs data communication with other name tag type portable electronic terminals and infrared transmitters by performing the above-described infrared communication, and stores the data in a memory as a storage device.

In this embodiment, the data acquired by the name tag type portable electronic terminal is inserted into the charger /

data transfer device

115, 125 as described above, and wired or wirelessly via the

personal computers

116, 126 and the Internet 101. And stored in the server 102. When the video conference ends or returns home, the user can insert the name tag type

portable terminal

portable terminals

113, 114, 123, and 124---are inserted, the acquired data in the memory can be stored in the server 102 via a wired or wireless connection.

Here, the unique ID transmitted by the

infrared transmitters

111 and 121 is linked to the

video conference devices

112 and 122 so that infrared rays are transmitted only during the video conference. If a different ID is sent to each destination, that is, each site, the IDs received by the name tag type portable

electronic terminals

113, 114, 123, and 124 ------- You can know if you went.

Here, an example in which a video conference is performed at two sites has been described, but it goes without saying that a video conference at three or more sites can be similarly performed.

FIG. 2 is a diagram illustrating an example of a processing sequence for acquiring face-to-face information when a video conference is performed at a specific location of the two

sites

1 and 2 according to the first embodiment.

Since the same processing is performed at site 1 and site 2, the processing at site 1 will be described here. The infrared transmitter 1 periodically transmits a unique ID, and the name tag type terminal 1 which is a name tag type portable electronic terminal receives this ID irregularly. Since the name tag type terminal 1 is worn by the user as described above, whether or not to receive the ID transmitted by the infrared transmitter 1 is irregular because it depends on the direction of the body. The infrared transmitter 1 is preferably installed in accordance with the direction of the user. For example, in the case of a video conference, it is one idea to install it around the screen of the television. Depending on how accurately the conference time is measured, the interval at which the infrared transmitter 1 transmits the ID may be, for example, about once per second. Even in a short meeting of about 10 minutes, the probability that the name tag type terminal 1 will receive the ID is sufficient.

The name tag type terminal 1 that has received the ID executes the infrared reception process 201 of FIG. 2 in order to analyze the ID and store it in a memory (not shown) that is an internal storage device. A plurality of receptions are performed in one meeting, and each time infrared reception processing 201 is executed and recorded in the name tag type terminal 1. The name tag type terminal 1 not only receives the ID transmitted by the infrared transmitter 1 but also transmits and receives IDs between the name tag type terminals by infrared and obtains face-to-face information between users, and each name tag type terminal To record.

As described above, the name tag type terminal 1 is inserted into the data transfer device 1 at the end of the conference or when the user returns home, and the data recorded on the name tag type terminal 1 is transmitted to the server by the data transmission processing 203 via wired or wireless connection. Forward.

By executing the same processing at the site 2, the recorded data is transferred to the server, so that the server 102 can detect the meeting of the members between the

sites

1 and 2 that are conducting the video conference. .

3 is an example of an infrared transmitter ID table required when performing data analysis in the server 102 in this embodiment.

In this example, the conference room A and conference room B, which are specific locations, are located at the site 1, and the conference room 1001, conference room 1002, and conference room 1003, which are specific locations, are located at the site 2. Assume that there is a conference device. As shown in FIG. 3, the ID transmitted by the infrared transmitter of the conference room at each site has a value unique to the combination of a plurality of conference rooms at site 1 and site 2. Therefore, each name tag type terminal that has received this ID can determine which conference room and which conference room it has received when the video conference is being held. For example, if a name tag type terminal receives 0x20011001 (first line of the ID table) as an ID, it means that it participated in a video conference between the conference room A at site 1 and the conference room 1001 at site 2. I understand. Note that the ID table shown in FIG. 1 only needs to be held by the server that analyzes the data (the server 102 in FIG. 1).

FIG. 4 shows an example of analyzing the result of obtaining the face-to-face information when performing a video conference at two sites in the present embodiment, and displaying the face-to-face information on the display displays of the

PCs

116, 126, the server 102, and the like based on the analysis result. It is an example of the network diagram displayed above.

Here, A01, A02, A03, and A04 are members of site 1, and B01, B02, B03, B04, B05, and B06 are members of site 2. In the figure, a solid line indicates that there was a meeting between members within the site. For example, the solid line 411 represents that the members A01 and A02 face each other. On the other hand, a broken line shows that there was a meeting of members between sites. For example, the broken line 421 indicates that the member A01 and the member B01 face each other. The meeting in the site is detected by transmitting and receiving each other's ID by infrared communication between name tag type portable electronic terminals as described above. In addition, the meeting between the sites was detected when the name tag type portable electronic terminal received the ID of the infrared transmitter in the video conference. From this, it can be seen that A01 and B01, B02, and B02 and A01, A03, A04 at least once held a video conference.

Here, when outputting the analysis result to the display screen of the display, the length of the solid line and the broken line may be changed according to the facing time between the members. For example, the distance between members having a long meeting time may be shortened. In this way, the internal and external relationships are displayed in an easy-to-understand manner.

From the network diagram based on the analysis result of the face-to-face information by the system of this embodiment, it is possible to analyze the cooperation between the members in the organization, the identification of the members that are joined between the organizations, and the like. Based on this, it can be used for efficient management of the organization. For example, it can be used to activate the organization and review the organization organization.

FIG. 5 is a diagram showing a system configuration for acquiring face-to-face information when conducting a video conference at two sites according to the second embodiment. In this embodiment, instead of the

infrared transmitters

111 and 121 of the first embodiment, infrared transmitters / receivers connected to personal computers as information processing units are used.

Here, 101 is the Internet, 102 is a server, 511 is an infrared transmitter / receiver at

site

1, 112 is a video conference device at

site

1, 113 and 114 are name tag type portable electronic terminals at

site

1, and 115 is at site 1 A charger / data transfer device, 116 is a personal computer (PC) at site 1, 521 is an infrared transmitter / receiver at

site

2, 122 is a video conference device at

site

2, 123 and 124 are name tag type mobile phones at site 2 An electronic terminal, 125 is a charger / data transfer machine at

site

2, and 126 is a personal computer (PC) at site 2.

In the system of the present embodiment, the site 1 and the site 2 perform the video conference by the

video conference devices

112 and 122 in the same manner as the first embodiment. At this time, all members participating in the video conference wear name tag type portable electronic terminals of the same type as the name tag type portable

electronic terminals

113, 114, 123, and 124. Each of these name-tag type portable electronic terminals has a unique ID, and it is possible to detect who and who are facing each other by transmitting and receiving this ID by infrared rays as in the system of the first embodiment. .

In the present embodiment, the infrared transmitters / receivers 511 and 521 are different from the first embodiment in that the members participating in the video conference are detected by receiving the ID transmitted by the name tag type portable electronic terminal. .

Data obtained by the name tag type portable electronic terminal is transferred to the server 102 via the

personal computers

116 and 126 and the Internet 101 by inserting each terminal into the charger /

data transfer devices

115 and 125 as in the first embodiment. Stored. Similar to the first embodiment, the user may insert the name tag type portable electronic terminal into the charger /

data transfer device

115 or 125 when the video conference ends or returns home.

As described above, the infrared transceivers 511 and 521 are connected to the

personal computers

116 and 126, and the received infrared ID information is stored in the server 102 via the Internet 101. Here, the operation of the infrared transmitters / receivers 511 and 521 to receive the infrared ID is linked with the video conference apparatus so that the infrared rays are received only during the video conference.

Further, the infrared ID received by the infrared transmitter / receiver 511 of the site 1 may be transmitted from the infrared transmitter / receiver 521 of the site 2 via the personal computer 116, the Internet 101, and the personal computer 126. By receiving the infrared ID transmitted from the infrared transmitter / receiver 521 of the site 2 by the name tag type portable electronic terminal worn by the member of the site 2, the facing between the

sites

1 and 2 can be detected. Similarly, the infrared ID received by the infrared transmitter / receiver 521 of the site 2 may be transmitted from the infrared transmitter / receiver 511 of the site 1 via the personal computer 126, the Internet 101, and the personal computer 116. By receiving the infrared ID transmitted from the infrared transmitter / receiver 511 by the name tag type portable electronic terminal 113 or the like worn by the meeting participant member of the site 1, the meeting between the

sites

1 and 2 can be detected. I can do it. As described above, according to the present embodiment, it is possible to acquire face-to-face information between sites regardless of which site is conducting the video conference.

Here, an example in which a video conference is performed at two sites, that is, specific locations has been described, but a video conference at three or more sites can be similarly performed. In addition, by attaching an acceleration sensor or microphone to the name tag type mobile terminal and acquiring and collecting data, it is possible to measure the activity level of the conference from the movement of members and the amount of speech during the conference. Quality assessment is possible.

FIG. 6 is a diagram showing an embodiment of the internal block configuration of the infrared transceivers 511 and 521 of the present embodiment.

Here, 611 is an infrared transceiver, 601 is a microcomputer, 602 is an infrared transceiver driver, 603 is an infrared transceiver module, 604 is a pyroelectric motion sensor, 605 is a USB (Universal Serial Bus) module, and 606 is a power regulator.

Microcomputer (microcomputer) 601 performs infrared transmission / reception control and data transmission / reception control via USB. The infrared transmission / reception driver 602 processes a signal for performing infrared transmission / reception. The infrared module 603 has an infrared transmission device and an infrared reception device, and performs infrared transmission and reception.

The USB module 605 converts the serial communication of the microcomputer 601 to the USB standard. The power regulator 606 is a stabilized power source for operating the infrared transmitter / receiver 611 by USB power supply. Here, the 5 V voltage supplied from the USB is converted to 3 V used internally.

Pyroelectric motion sensor 604 detects human movement. Since the infrared transmitter / receiver 611 does not need to operate when there is no person, the infrared transmitter / receiver 611 can be shifted to the sleep state when there is no movement by the pyroelectric motion sensor 604 for a certain period of time. Thereby, power consumption can be reduced.

FIG. 7 shows a more specific configuration of the circuit diagram of the infrared transceiver 611 of the present embodiment shown in FIG. Here, 701 is a microcomputer, 702 is an infrared transmission / reception driver, 703 is a 4-input OR circuit, 704-707 is an infrared transmission / reception module, 708 is a pyroelectric motion sensor, 709 is a USB-serial conversion circuit, 710 is a USB connector, Reference numeral 711 denotes an ID setting switch for setting the ID of each infrared transmission / reception module from the P10-P13 terminals of the microcomputer 701.

When using a general-purpose product for the infrared transmission / reception module, there are problems such as a narrow communication angle and a short communication distance. Therefore, these problems can be solved by using a plurality of infrared transmission / reception modules as in this embodiment. Even if a plurality of infrared transmission / reception modules are used, the production cost can be significantly reduced by using a general-purpose product.

In order to use a plurality of infrared transmission / reception modules 704-707, the transmission signal TD from the microcomputer 701 may be simply distributed, but the reception signal RD is logically summed by the OR circuit 703 as in this embodiment. There is a need. As a result, any infrared module 704-707 can receive it into the infrared transmission / reception driver 702. Here, an example of positive logic is shown, but when the received signal RD is negative logic, a logical product may be taken.

The infrared transmission / reception driver 702 is connected to the microcomputer 701 by serial communication SCI2. The chip enable signal CE of the infrared transmission / reception module 704-707 is connected to the port of the microcomputer 701. By enabling individually, current consumption can be cut when unnecessary, and power consumption can be reduced. The USB-serial conversion circuit 709 is connected to the microcomputer 701 and the infrared transmission / reception driver 702 by serial communication SCI1 different from the microcomputer 701. By connecting the infrared transmission / reception driver 702 and the USB-serial conversion circuit 709 to different serial communications, it is possible to perform parallel processing and to operate at high speed. For this reason, the microcomputer 701 does not need such high performance, and an inexpensive microcomputer can be used.

The pyroelectric motion sensor 708 is connected to the interrupt pin IRQ of the microcomputer 701. As a result, it is possible to operate by detecting the movement of a person.

FIG. 8 is an example of a component layout diagram of the infrared transceiver according to the present embodiment shown in FIGS. The left side of the figure shows the outer surface viewed from the front, top, and back, and the right side shows the corresponding interior.

801-804 is an infrared transmission / reception module, 810 is a pyroelectric motion sensor, 820 is a USB connector, and 830 is a housing. By arranging the infrared transmission / reception modules 801-804 at an angle as shown in the figure, it is possible to solve the problem that the communication angle is narrow by one and secure a wide communication angle.

FIG. 9 is an example of a flowchart for explaining the operation of the infrared transceiver according to the second embodiment, particularly the operation of the microcomputer 701 in FIG. FIG. 9A shows a main loop. Here, initialization is executed in process 902, infrared reception interruption and motion sensor interruption are permitted in process 903, and it is confirmed whether there is an ID to be transmitted in process 904. Send ID. As an outline, it is an operation of waiting for an infrared reception interrupt and a motion sensor interrupt while periodically transmitting an infrared ID.

(B) in FIG. 9 shows the operation when the infrared transmission / reception module 801-804 receives an infrared reception interrupt due to the reception of the infrared radiation. The received data is read in process 912, the received ID is analyzed in process 913, and whether the ID is correct is determined in process 914. If correct, the received ID is transmitted to the personal computer in process 915. Since there is a lot of noise in the received infrared data, it is necessary to analyze whether the ID is correct. Therefore, the process 914 determines whether the ID is correct.

(C) of FIG. 9 is an operation when a motion sensor interrupt from the motion sensor 708 is entered. Here, the main operation is to transmit to the

personal computer

116 or 126 that the motion sensor 708 has reacted by the process 922.

FIG. 10 shows an example of the infrared ID communication signal in this embodiment.

Here, in the byte string 1001, the ID is 2-byte data. Then, a 2-byte CRC 16 is added so that the signal can be correctly identified even if noise is present. Therefore, the total amount of information is 4 bytes.

In the

bit string

1002, 1 bit of a start bit of

logical value

0 and 1 bit of stop bit of logical value 1 are added for every transmission of 1 byte, that is, 8 bits. This enables asynchronous serial communication.

And information is communicated according to whether or not the infrared ray 1003 emits 1-bit information. The logic is negative logic, light is emitted when the logical value is 0, and light is not emitted when the logical value is 1. In the case of light emission, the first 3 μs of 16 μs is emitted. Shortening the light emission time has the effect of reducing power consumption.

FIG. 11 is a diagram showing a third embodiment in which the installation position of the infrared transceiver in the second embodiment is changed. Since the configuration other than the installation position is the same as that of the second embodiment, description of inserting the charger /

data transfer devices

115 and 125 to transfer the acquired data, etc. will be omitted.

Here, 1101 is an infrared transceiver, 1102 is a personal computer body, 1103 is a display connected to the

personal computer body

1102, and 1104 is a USB cable for connecting the infrared transceiver 1101 and the personal computer body 1102. Here, an infrared transmitter / receiver 1101 is installed near the display 1103 of the personal computer, which is a feature of the configuration of this embodiment. When each user wearing a name tag type portable electronic terminal stands in front of the display 1103, the infrared transmitter / receiver 1101 receives the infrared ID transmitted from the name tag type portable electronic terminal, and the ID is transmitted to the personal computer 1102 via the USB cable 1104. Send to. In this way, it is possible to identify the ID of the user wearing the name tag type portable electronic terminal and display information unique to the user of the ID on the display 1103.

Here, 1201 is a display constituting the display unit, 1202 is the name of the user, 1203 is an action index which is one of analysis examples, 1204 is a graph showing the analysis result as an overall distribution, and 1205 is a comment regarding the analysis result. .

In the screen configuration of the present embodiment, both the amount and quality of the meeting are analyzed, and the meeting time, the number of meeting persons, the bias of the meeting members, the amount of speech, the moving time, and the meeting time are displayed as action indicators 1203. Among these, the meeting time, the number of meeting persons, and the bias of meeting members can be made by analyzing data acquired by infrared ID communication. The amount of speech can be acquired by a microphone equipped in a name tag type portable electronic terminal. The travel time can be acquired by a change in the user's movement measured by an acceleration sensor equipped in the name tag type portable electronic terminal. These data can be acquired by data transfer similar to that of the second embodiment. An example of the specific method of data analysis is disclosed in Patent Document 3 described above.
