Description

  The present invention is connected to a first system including a sensor that senses information related to a person's presence, movement, or environment, a second system that is connected to the first system and includes a display device, and the second system. The present invention relates to a communication system including a center server and a communication method in the communication system.

  When using a conventional communication system, for example, when making a phone call, the parties who make the call directly feel the presence of a person by talking to each other.

  In this case, since the other party who answers the telephone interrupts the thought that was performed immediately before, the work that was being performed until immediately before the telephone is interrupted.

  To avoid interrupting the other person's thoughts, use email instead of the phone. Since the e-mail can be read at the convenience of the other party, the other party's thinking is not interrupted.

  However, since e-mail lacks real-time properties, there are problems that the other party is present or cannot have a presence or the like in real time.

  Therefore, when knowing the presence information of the other party, the person's thoughts are not interrupted, and the presence of the other party can be held in real time. There is a method of transmitting a sense of connection without any information (for example, see Patent Document 1).

  In the method described in Patent Document 1, a communication terminal is used in which a sensor detects information on the presence, movement, or environment of a person, outputs sensor information, and transmits and receives the sensor information to and from a partner apparatus. The communication terminal includes: a transmission unit that transmits sensor information acquired by a sensor to a communication network; a reception unit that receives the sensor information transmitted by the counterpart device via the communication network; and the reception unit that receives the sensor information. An operation execution unit that executes an operation according to the sensor information. As a result, the motion execution unit executes an operation according to information on the movement or environment of the remote person, thereby semi-explicitly transmitting the movement of the remote person.

  In the method described in Patent Document 1, for example, a sensor is installed at an end user house to be watched, and a display device is installed at the end user house to be watched. At the end user's home to be monitored, sensor information is acquired from the monitored end user's home. At the end user's home to watch, a predetermined program generates display information for display on the display device from the acquired sensor information.

Various types of sensors included in the first user system 11 and display devices included in the second user system 21 can be considered. For the sensor and the display device, the type of the display device to be displayed may be determined according to the type of the sensor. Here, an example of the sensor will be described with reference to FIGS.

  A sensor 101 shown in FIG. 2 is a speed sensor 101. The speed sensor 102 includes an ultrasonic sensor main body 101a, an ultrasonic transmission unit 101b, an ultrasonic reception unit 101c, and a speed sensor board 101d. The temperature sensor board 101d includes a temporary storage unit 101e, a calculation unit 110f, an external interface 101g, and a bus 101h. The bus 101h connects the ultrasonic sensor main body 101a, the temporary storage unit 101e, the calculation unit 101f, and the external interface 101g.

  The speed sensor 102 transmits an ultrasonic wave forward from the ultrasonic transmission unit 101b, and the transmitted ultrasonic wave is reflected by an object existing in front and is input to the ultrasonic reception unit 101c. At this time, a time T0 [s] from transmission to input is measured, and the measured time is sent to the calculation unit 101f. The calculation unit 101f obtains the distance L0 [m] to the object from the sound speed V [m / s] and the time T0. The distance data L0 [m] is stored in the temporary storage unit 101e. After T [s] from the previous measurement, the speed sensor 101 performs the same measurement as described above, and measures the distance L1 [m] to the object.

  Next, the calculation unit 101f obtains the average moving speed (L1-L0) / T [m / s] of the object based on the distance data L0 and the distance L1 stored in the temporary storage unit 101e, and obtains this. The result is transmitted via the external interface 101g.

  A sensor 102 illustrated in FIG. 3 is a temperature sensor 102. The temperature sensor 102 includes an infrared CCD sensor 102a, a temporary storage unit 102b, a calculation unit 102c, an external interface 102d, and a bus 102e.

At this time, the potential detection unit 102c transmits information that a person has touched it via the external interface 103d.

  Next, an example of a display device will be described.

  The display device includes, for example, a motor and a driven member that is driven by the motor. When the display device receives speed information from the speed sensor as sensor information from the first user system 11, the display device controls the rotational speed of the motor according to the size of the received speed information and changes the way the driven member swings. Let The display device represents the movement of the person in the first user system 11 by the second user system 21 by the shaking of the driven member.

  The display device includes, for example, a plurality of LEDs, an optical fiber, and a motor that drives the optical fiber. When the display device receives speed information from the speed sensor as sensor information from the first user system, the display device controls the rotation speed of the motor according to the magnitude of the speed information, and changes the manner of shaking of the optical fiber. Further, the display device controls the intensity of the LED light or the way it shines according to the address information of the user system 11 that is the transmission source. Thereby, the display device can express the movement of the person in the first user system 11 by the second user system 21.

  The display device is, for example, a speaker. When the contact information by the touch sensor is received as sensor information from the first user system 11, the display device outputs a preset sound from the speaker. As a result, the display device can express the contact state of the touch sensor installed in the first user system 11 with the second user system 21.

  The display device is, for example, a computer including a display device. When the speed information by the speed sensor or the contact information by the touch sensor is received as sensor information from the first user system 11, the display device displays a moving image corresponding to the speed information or the contact information on the display device. For example, when the speed information has a speed equal to or higher than a certain value, a moving image in which the character moves quickly can be created and displayed on the display device. In addition, when the frequency of contact information by the touch sensor is high, a moving image including a large number of characters can be created and displayed on a display device.

  As mentioned above, although an example of the sensor and the display apparatus was demonstrated, it is not restricted to these. Further, a case where display information is generated by combining a plurality of sensor information and displayed on a plurality of display devices is also conceivable.

The display device type, the sensor type of the first sensor, the sensor type of the second sensor, and the sensor type of the third sensor are not extracted. Similarly, in the display device information data 303a, since the third display device 203 of the display device type D203 cannot correspond to the third sensor 103 of the sensor type S103, the third display from the program corresponding data 301a. It is not necessary to search for a program in which the display device type of the device is associated with the sensor type of the first sensor, the sensor type of the second sensor, and the sensor type of the third sensor. As described above, the transmission / reception analysis unit 306 takes into consideration the incompatible sensor type for each display device when searching for a program for creating display information for displaying all sensor information included in the transmission information on the display device. Search for a program.

  Further, the transmission / reception analysis unit 306 searches the management data 304a to determine whether or not these programs are held by the second user system 21. Specifically, the transmission / reception analysis unit 306 determines whether or not the identifiers P17, P23, and P33 of these programs are associated with the identifier G102 of the second user system 21 in the management data 304a. In the example shown in FIG. 10, since the identifiers P17, P23 and P33 of these programs are not associated with the identifier G102 of the second user system 21, the transmission / reception analysis unit 306 includes the program identifier P17 together with the transmission information. The programs corresponding to P23 and P33 are transmitted to the second user system 21 via the transmission / reception means 305.

  Further, when the transmission of the program is completed, the transmission / reception analysis unit 306 registers in the management data 304a that the second user system 21 has the program. Specifically, the transmission / reception analysis unit 306 inserts a record that associates the identifier G102 of the second user system 21 with the identifiers P17, P23, and P33 of the transmitted program into the management data 304a. FIG. 11 shows the data of the management data 304a in that case. The management data 304a shown in FIG. 11 includes a record that associates the identifier G102 of the second user system 21 with the identifiers P17, P23, and P33 of the transmitted program.
