FIELD OF THE INVENTION
The present invention relates to a technology for teaching or giving a training to trainees on how to operate a device by an instructor. The instructor and the trainees are located at remote places.

In recent years, space development has become increasingly progressive, and tests of new materials under conditions of weightlessness in space, and life science tests to determine the effects of weightlessness on life, are being carried out.
To conduct a great number of tests in a limited number of days in outer space, the test device is prepared for testing on earth, provided in a rack, and loaded into a test module of the spacecraft. The test module is launched from the earth. While in space, the spacecraft carries out the tests over a period of days while following a predetermined orbit.
For example, when testing a material, minimal operations, such as loading and interchanging the material, are performed manually at the start and end of the test. On the other hand,

a range of operations such as melting by heating (setting the time, temperature, etc.) and analyzing the components of the melted metal are performed by connecting a computer for control to a microcomputer provided in the test device via a cable, and inputting a test sequence, a control quantity, and the like, from the computer for control to the microcomputer.
Based on the test sequence and the control quantity, the microcomputer melts the material by heat and analyzes its components by controlling various apparatuses provided in the test device, such as a heating furnace and a handling apparatus. In addition, the microcomputer creates a graph from the resulting data of the component analysis.
Since the number of researchers aboard the test module orbiting the earth in outer space is severely restricted, a great number of tests must be performed by a small number of people. For this reason, prior to travelling to outer space, the researchers must undergo training in each of the individual tests, and practice the operations.
The people (trainees) who undergo this training, technicians (instructors) adept at operating the test device, and where necessary other people (assistants) who have detailed knowledge of the contents of the tests, such as the people who devised the tests, meet at a place (training center) where the tests are to be carried out.
During training, the instructors (and where necessary the

assistants) teach the trainees how to input the test sequences, the control quantities, and the like, into the computer for control. Workers are responsible for operations such as loading and interchanging the materials.
However, in such training, since the instructors, the trainees, and where necessary the assistants, must meet at the training center, the time and costs required to reach the training center when the above personnel reside in remotely separated locations, cannot be overlooked.
In particular, when tests are carried out with international cooperation, personnel must travel from other countries to perform the tests. In order to accommodate the schedules of the personnel involved, there are inevitable restrictions on the test period and the cost of transporting and housing the personnel is high.
SUMMARY OF THE INVENTION .
It is an object of this invention to provide a remote training method, a remote training device, a remote training system. It is another object of this invention to provide a remote teaching method, a remote teaching device, a remote teaching system. It is still another object of this invention to provide a computer-readable recording medium which records a computer program which when executed realizes the methods according to the present invention. The present invention aims

to provide the technology which enables teaching or training to the trainees easily and at low cost.
According to the present invention, identical formats for training are displayed with respect to the instructor and the trainee. Incidentally, computers with display sections are provided at the respective sides, that is the instructor side and the trainee side, and the corresponding information is displayed on the corresponding display section. The instructor and the trainee communicate (audio communication) with each other, and any one of the instructor and the trainee enters predetermined data into the formats. If the instructor enters the data, it is transmitted to the computer provided at the trainee side and displayed with respect to the trainee. On the other hand, if the trainee enters the data, it is transmitted to the computer provided at the instructor side and displayed with respect to the instructor. Thus, the instructor and the trainee perform training based on audio communications exchanged via a communications line. Therefore, the instructor and the trainee do not need to meet, enabling various types of training to be carried out easily and at low cost, and time restrictions to be reduced.
Other objects and features of this invention will become apparent from the following description with reference to the accompanying drawings.

The status of a lamp inside the test device 110 is displayed in the lamp status region Z20. The status of a back light is displayed in the back light region Z21. Control quantity input sections Z23 and Z24 which input control quantities for controlling the movement of the material and various types of apparatus in the test device 110, and buttons Z25, Z26, and the like, for executing the movement-control, are displayed in the movement control region Z22.
Returning to Fig. 1, the support server 160 is connected to the local area network 140, and supports tests and the like of the test device 110 . The computer for training 310 is provided in Japan 300, and is connected to the network 200. The computer for training 310 is operated by an instructor 320 or an assistant who has been trained to operate the test device 110 and the computer for control 120. The computer for training 310 is used to train

a trainee 420 based in the USA 400 how to operate the computer for control 120.
The computer for training 310 comprises a main body 311, a display 312, a keyboard 313, and a mouse 314. The display 312 displays an input format FA which is identical to the input format F0 displayed in the display 122 of the computer for control 120 in the training center 100. That is, the computer for training 310 is a terminal capable of the same operations as the computer for control 120.
A telephone 330 is connected to the network 200, and is used to enable the instructor 320 and the trainee 420 to communicate by voice when contacting each other during training relating to the computer for control 120.
On the other hand, the computer for training 410 is provided in the USA 400, and is connected to the network 200 . The computer for training 410 is operated by the trainee 420 who requires a training by the instructor 320 on how to operate the computer for control 120. The trainee 420 receives instruction from the instructor 320 in Japan 300, and undergoes training to operate the computer for control 120 using the computer for training 410.
The computer for training 410 comprises a main body 411, a display 412, a keyboard 413, and a mouse 414. The display 412 displays an input format FB which is identical to the input format F0 displayed on the display 122 of the computer for control

120 in the training center 100. That is, the computer for training 410 is a terminal capable of the same operations as the computer for control 120.
A telephone 430 is connected to the network 200, and is used to enable the instructor 320 and the trainee 420 to communicate by voice when contacting each other during training relating to the computer for control 120.
The constitution of the computers for training 310 and 410 will be explained in detail with reference to Fig. 4. The computer for training 310 comprises a communications section 315, a control section 316, an input/output interface 317, and a memory 318. The communications section 315 controls communications in compliance with a predetermined communications protocol.
The control section 316 controls all sections of the computer for training 310 . The operation of this control section 316 will be explained in detail later. The memory 318 stores all types of data input to the input format FA, and an input format creationprogram319whichautomaticallycreates the input format FA. The input/output interface 317 functions as an interface between the control section 316 and the display 312, the keyboard 313, and the mouse 314.
On the other hand, the computer for training 410 comprises a communications section 415, a control section 416, an input/output interface 417, and a memory 418. The

communications section 415 controls communications in compliance with a predetermined communications protocol.
The control section 416 controls all sections of the computer for training 410 . The operation of this control section 416 will be explained in detail later. The memory 418 stores all types of data input to the input format FB, and an input format creationprogram419 which automatically creates the input format FB. The input/output interface 417 functions as an interface between the control section 416 and the display 412, the keyboard 413, and the mouse 414.
The operation of the first embodiment will be explained here. The instructor 320 and the trainee 420 talk to each other
using the telephones 330 and 430. This process is the start
i
of the training. Thereafter, the instructor 320 and the trainee 420 continue to talk to each other using the telephone till the end of the training.
The instructor 320 activates the computer for training 310 and inputs a command, using the keyboard 313, to instruct to create an input format. Accordingly, the control section 316 creates the input format FA which is identical to the input format F0 by executing the input format creation program 319. The input format FA is displayed with respect to the instructor 320 on the display 312.
The trainee 420 also activates the computer for training 110 and inputs a command, using the keyboard 413, to instruct

to create an input format. Accordingly, the control section 416 creates the input format FB which is identical to the input format FO by executing the input format creation program 419. The input format FB is displayed with respect to the trainee 420 on the display 412.
At this point, the display 312 in Japan 300 and the display 412 in the USA 400, shown in Fig. 1, are displaying identical input/output formats (input format FA and input format FB). Therefore, the state is virtually the same as if the instructor 320 and the trainee 420 were meeting at the training center 100.
In this state, the instructor 320 uses input devices such as the mouse 314 and the keyboard 313 to input data which is required to operate the test device 110 into the input format FA. When inputting the data, the instructor 320 contacts the trainee 420 by telephone, and informs himof precise instructions, methods, etc.
The control section 316 controls the operation so that the data input by the instructor 320 is displayed in the input format FA displayed on the display 312, and is also sent via the communications section 315 and the network 200 to the computer for training 410 of the trainee 420.
Consequently, the data is input via the communications section 415 to the control section 416, which controls the operation so that the data is displayed in the input format FB on the display 412. That is, the display 312 and the display

412 both display the same data input by the instructor 320. The trainee 420 is trained by the instructor 320 while contacting him by telephone and viewing the display 412.-
The data input by the trainee 420 is also sent to the computer for training 310 of the instructor 320. That is, in compliance with the control section 416, the data input by the trainee 420 is displayed in the input format FB displayed on the display 412, and in addition, is sent via the communications section 415 and the network 200 to the computer for training 310 on the instructor 320 side.
Therefore, the above data is input via the communications section 315 to the control section 316, and displayed in the input format FA on the display 312 in compliance with the control section 316. That is, the display 312 and the display 412 both display the same data input by the trainee 420. Consequently, by checking the data displayed on the display 312, the instructor 320 is able to learn the training results and progress of the trainee 420.
The above explanation of the first embodiment described an example in which the input format creation program 319 and the input format creation program 419 are held in the computer for training 310 and the computer for training 410, and respectively create the input format FA and the input format FB. Alternatively, however, an input format creation program may be held in only one of the computers for training.

As an example, the input format creation program 319 is held in the computer for training 310, but the input format creation program 419 is not held in the computer for training 410. In this case, the input format FA created by executing the input format creation program 319 of the computer for training 310 need only be sent via the network 200 to the computer for training 410. Therefore, the computer for training 410 displays the received input format FA on the display 412. According to this constitution, the memory region of the memory 418 in the computer for training 410 can be made smaller.
The above first embodiment described an example in which the telephones 330 and 430 were used for audio contact during training. However, training may be conducted using a television conference system which transmits audio and visual signals between the two sides. This case will be explained below as a second embodiment.
Fig. 5 is a diagram showing the constitution of the second embodiment. In the diagram, parts corresponding to those of Fig. 1 are represented by the same reference codes. In Fig. 5, the telephones 330 and 430 shown in Fig. 1 are substituted by television conference devices 340 and 440, and a television conference controller 500, for realizing a tele vis ion conference system.
The television conference device 340 is provided in the vicinity of the computer for training 310, and effectively

realizes training between the instructor 320 and the trainee 420 using audio and visual signals (television conferencing). The television conference device 340 is connected to the network 200, and comprises a main body 341, a monitor 342, a microphone 343, a speaker 344, and a CCD camera 345.
The main body 341 controls coding/decoding of audio data, coding/decoding of visual data, communications, and the like. The monitor 342 displays an image of the trainee 420 captured by a CCD camera 445 (described later) in compliance with the main body 341. The microphone 343 mainly converts the voice of the instructor 320 into audio data, and outputs this audio data to the main body 341.
The speaker 344 reproduces audio data, which has been decoded by the main body 341, as the voice of the trainee 420. The CCD camera 345 is provided directly behind or diagonally behind the instructor 320, and films him operating the computer for training 310. The CCD camera 345 sends the image as image data to the main body 341. The main body 341 controls the zoom and angle of the CCD camera 345.
On the other hand, the television conference device 440 provided on the trainee 420 side is connected to the network 200, and comprises a main body 441, a monitor 442, a microphone 443, a speaker 444, and a CCD camera 445.
The main body 441 controls coding/decoding of audio data, coding/decoding of visual data, communications, and the like.

In compliance with the main body 441, the monitor 442 displays an image of the instructor 320 captured by the CCD camera 345. The microphone 443 mainly converts the voice of-the trainee 420 into audio data, and outputs this audio data to the main body 441.
The speaker 444 reproduces audio data, which has been decoded by the main body 441, as the voice of the instructor 320 . The CCD camera 445 isprovided directly behind or diagonally behind the trainee 420, and films him operating the computer for training 410. The CCD camera 445 sends this image as image data to the main body 441. The main body 441 controls the zoom and angle of the CCD camera 445.
The television conference controller 500, which is connected to the network 200, temporarily receives audio data and image data from the main body 341 and the main body 441, and sends them to the counterpart (i.e. the main body 441 or the main body 341).
The operation of the second embodiment will be explained here. The instructor 320 and the trainee 420 start the training using the television conference device 340 and the television conference device 440. The voice of the instructor 320 is transmitted to the trainee 420 via the microphone 343, the main body 341, the network 200, the television conference controller 500, the network 200, the main body 441, and the speaker 444.
Simultaneously, the image of the instructor 320 is

transmitted to the trainee 4.20 via the CCD camera 345, the main body 341, the network 200, the television conference controller 500, the main body 441, and the monitor 442.-
The voice of the trainee 420 is transmitted to the instructor 320 via the microphone 443, the main body 441, the network 200, the television conference controller 500, the network 200, the main body 341, and the speaker 344.
Simultaneously, the image of the trainee 420 is transmitted to the instructor 320 via the CCD camera 445, the main body 441, the network 200, the television conference controller 500, the main body 341, and the monitor 342 . Thereafter, the instructor 320 and the trainee 420 continue to contact each other by exchanging audio and image data using the television conference system, while performing training in the same manner as in the first embodiment.
The first and second embodiments described examples in which the instructor 320 and the trainee 420 perform training relating to the operation of the computer for control 120, but the training may comprise direct operation of the test device 110. This case will be explained as a third embodiment.
Fig. 6 is a block diagram showing a constitution of the third embodiment. In this diagram, parts corresponding to those of Fig. 1 are represented by the same reference codes. In Fig. 6, a sample container 113, a laser oscillator 114, a CCD camera 115, an image processor 170, and a display 171, are provided

in the training center 100.
The sample container 113 is provided in the test device 110, and contains a sample for testing. The laser oscillator 114 radiates laser light onto the sample in the sample container 113 . The CCD camera 115 films changes and the like of the sample in the sample container 113.
That is, the images taken by the CCD camera 115 show the status of the test in the test device 110. The image processor 170, which is connected to a local area network 140, processes the image data from the CCD camera 115, and displays is on the display 171. For example, a test status screen Y0 (see Fig. 8) is displayed on the display 171.
Fig. 7 is a block diagram showing a detailed constitution of the third embodiment. In this diagram, parts corresponding to those of Fig. 6 are represented by the same reference codes. A support server 160 shown in Fig. 7-comprises a control section 161, a memory 162, and a network card 163.
The control section 161 controls the execution of commands relating to operating the test device 110. The operation of the control section 161 will be explained in detail later. The memory 162 stores the management database DB shown in Fig. 9. The management database DB contains various types of data such as "receiving order", "operation command", "completion flag", "action result data", and "sender data".
The "receiving order" comprises data showing the sequence

in which the support server 160 has received the operation commands from the computer for training 310 and the computer for training 410. Here, operation commands are commands for controlling all parts of the test device 110. In outer space, the astronaut inputs the operation commands using the computer for control 120.
The "operation command" comprises data showing the type of the operation command sent from the computer for training 310 and the computer for training 410. The "completion flag" is a flag showing whether the execution of the operation command has been completed, a value of "1" signifying completion of the command, and "0" signifying that the execution is incomplete. The "action result data" comprises data showing an action result of the test device 110 after the operation command has been completed. The "sender data" is data for identifying the sender of the operation command. "PA" = the instructor 320, and "PB" = the trainee 420.
The operation of the third embodiment will be explained with reference to the flowchart shown in Fig. 10. At Step SA1, the control section 161 of the support server 160 determines whether or not an operation command has been received from the computer for training 310 or the computer for training 410. When a result of this determination is "No", the control section 161 repeats the same determination.
When, for the purpose of training, the instructor 320 uses

the keyboard 313 to input an operation command CA to the input format FA (see Fig. 3) , the control section316 sends the operation command CA, together with sender data PA identifying the instructor 320, to the support server 160 via the communications section 315, the network 200, the router 150, and the local area network 140.
When the control section 161 receives the operation command CA and the sender data PA via the network card 163, the result of determination at Step SA1 will be "Yes". At Step SA2, the control section 161 sets the operation command CA and the sender data PA in one record (receiving order = 1) of the management database DB shown in Fig. 9.
At Step SA3, the control section 161 sends the operation command CA to the test device 110 via the network card 163, the local area network 140, the computer for control 120, and the cable 130 . Consequently, the test device 110 acts in compliance with the operation command CA.
At Step SA4, the control section 161 determines whether or not the action based on the operation command CA has been completed. When a result of this determination is "No", the control section 161 repeats the determination until the action is completed. When the action is completed, the control section 161 determines a result of "Yes" at Step SA4. At Step SA5, the control section 161 sets the completion flag to 1 (completion) in one record (receiving order = 1) of the management database

DB shown in Fig. 9.
At Step SA6, the control section 161 extracts an action result data JA from the test device 110 via the test device 110, the cable 130, the computer for control 120, the local areanetwork 140, and the network card 163. Then, the control section 161 sets the action result data JA in one record (receiving order = 1) of the management database DB shown in Fig. 9.
At Step SA7, the control section 161 sends the action result data JA via the network card 163, the router 150, and the network 200, to the computers for training 310 and 410. Consequently, the action result data JA corresponding to the operation command CA input by the instructor 320 is displayed on the displays 312 and 412.
At Step SA8, the control section 161 determines whether or not the next operation command (in this case, operation command CC, receiving order = 2) is set in the management database DB. When the determined result is "No," the control section 161 executes the processing from Step SAl onwards. Further, when the result determined at Step SA8 is "Yes", the control section 161 executes the processing from Step SA3 onwards.
During the above training, the image recorded by the CCD camera 115 (the state of the sample in the sample container 113 (see Fig. 6} ) is input to the image processor 170 as image data, and image-processed. Consequently, the test status screen Y0 shown in Fig. 8 is displayed on the display 171.

Further,- the support server 160 sends the image data from the-image processor 170 via the router 150 and the network 200 to the computer for training 310 and the computer for training 410.
As a consequence, a test status screen YA, which is identical to the test status screen Y0, is displayed on the display 312 of Fig. 6, and a test status screen YB, which is identical to the test status screen Y0, is displayed on the display 412. Therefore, the instructor 320 and the trainee 420 are able to confirm both screens, and carry out training on the test device 110 based on the operation commands while being located at a remote distance from each other.
The above third embodiment described an example comprising the telephones 430 and 330 shown in Fig. 6, but these may be substituted by the television conference system mentioned in the second embodiment. This case will be explained as a fourth embodiment.
Fig. 11 is a block diagram showing a constitution of the fourth embodiment. In this diagram, parts corresponding to those of Fig. 6 are represented by the same reference codes. In Fig. 11, the telephone 330 and telephone 430 are substituted by a television conference device 340, amicrophone343, aspeaker 344, a television conference device 440, a microphone 443, a speaker 444, and a television conference controller 500. The detailed constitutions of the television conference device 340

and the like have already been described in the second embodiment.
Fig. 12 shows a detailed constitution of the fourth embodiment. In Fig. 12, parts corresponding to those of Fig. 7 and Fig. 11 are represented by the same reference codes.
The operation of the fourth embodiment will be explained here. In Fig. 12, the instructor 320 and the trainee 420 start the training using the television conference device 340 and the television conference device 440 in the same manner as in the second embodiment.
