When the student operates the CAD device 1 and inputs a questionnaire response (in the example of FIG. 4, a check is put in □), the CAD device 1 sends the questionnaire response to the CAD development device 2 via the network 4. Send.

As described above, when the CAD device 1 transmits a questionnaire response, the response collection processing unit 12 of the CAD development device 2 performs a process of collecting the questionnaire response via the network I / F 11 (Step S1). ST1).
For example, if the number of students performing this exercise item is 100, answers to questionnaires of 100 students are collected.

The response aggregation processing unit 13 of the CAD development apparatus 2 has a predetermined number of questionnaire responses collected by the response collection processing unit 12 (for example, a predetermined number if the number of students performing this exercise item is 100). When “100” is reached (step ST2), a process of collecting the questionnaire responses collected by the answer collection processing unit 12 is performed (step ST3). The predetermined number “100” is merely an example, and may be “80”, for example.
Specifically, it is as follows.
For example, when collecting the answers to the question (1), the answer aggregation processing unit 13 compares the selection numbers of the answers A, B, and C with respect to the question (1), and selects the answer as the answer to the question (1). Aggregate the answers with the largest number.
For example, if the number of answers A selected is “20”, the number of answers B selected is “30”, and the number of answers C selected is “50”, the answers of question (1) are collected in the answer C. That is, the answer to the question (1) is unified so that the answer C is the only answer.

The modification processing unit 14 of the CAD development apparatus 2 performs a process of modifying the processing program of the CAD apparatus 1 according to the answers after the aggregation when the answer aggregation processing unit 13 aggregates the answers of the questionnaire (step ST4).
For example, if the answer to question (1) is answer A, the modification contents that enlarge the text of the CAD operation explanation text. If the answer to question (1) is answer C, the text of the CAD operation explanation text is reduced. If the answer to question (1) is answer B, if the contents for maintaining the size of the CAD operation description text are prepared in advance, for example, the answer after aggregation is the answer C If so, the processing program or the like of the CAD device 1 is modified so that the characters in the CAD operation description are reduced.
Further, if the answer after aggregation is answer A, the processing program of the CAD device 1 is modified so that the text of the operation description of the CAD becomes larger. If the answer after aggregation is answer B, the CAD Keep the text size of the operation description.
When the modification processing unit 14 of the CAD development device 2 modifies the processing program of the CAD device 1, the modification processing unit 14 transmits the modified processing program to the ASP server 3 via the network 4 (step STST5).

As a result, the ASP server 3 discards the old processing program and stores the modified processing program.
At this stage, the CAD device 1 has been repaired once.
When the university student again operates the CAD device 1 and instructs to start the processing program, the CAD device 1 is a version of the processing program installed inside and the version of the processing program stored in the ASP server 3. If the version of the processing program stored in the ASP server 3 is newer, the processing program stored in the ASP server 3 is downloaded and stored in the internal memory, and then the processing program is started. To do.
Hereinafter, since the operation after starting the processing program is as described above, the description thereof will be omitted. In this case as well, a questionnaire response regarding each exercise item is transmitted to the CAD development device 2, and the CAD development device 2. Revises the processing program of the CAD device 1 according to the answer of the questionnaire.

  As is apparent from the above, according to the first embodiment, the answer collection processing unit 12 that collects the questionnaire responses regarding the field test of the CAD device 1 and the questionnaire responses collected by the answer collection processing unit 12 When the number reaches a predetermined number, a response aggregation processing unit 13 that aggregates the responses of those questionnaires is provided, and the CAD device 1 is modified according to the responses of the questionnaires aggregated by the response aggregation processing unit 13 As a result, it is possible to easily reflect the demands and indications of students who actually use the CAD device 1 on the CAD device 1.

  Further, according to the first embodiment, when the field test is composed of a plurality of exercise items, each time one exercise item is completed, the questionnaire responses regarding the exercise item are collected. Before you forget the experience of this exercise item, you can answer the questionnaire.

  In the first embodiment, the components of the CAD development device 2 (network I / F 11, answer collection processing unit 12, answer aggregation processing unit 13, and modification processing unit 14) are configured by individual hardware. However, when the CAD development apparatus 2 is configured by a computer, a program describing the processing contents of the components of the CAD development apparatus 2 is stored in the memory of the computer, and the CPU of the computer is stored in the memory. The program may be executed.

Embodiment 2. FIG.
In Embodiment 1 described above, the answer aggregation processing unit 13 of the CAD development apparatus 2 compares, for example, the selection numbers of the answers A, B, and C with respect to the question (1), and the answer to the question (1) In the above description, the answers that are aggregated into the most frequently selected answers are shown. However, the answers to the question (1) may be aggregated in consideration of the balance of the number of answers A, B, and C selected.

For example, when the number of answers A selected is “30”, the number of answers B selected is “30”, and the number of answers C selected is “40”, the answer having the largest number of choices as in Embodiment 1 above. If they are aggregated, the answer to question (1) is aggregated into answer C.
In this case, the selection rate of the answer C that “Large text” is 40%, whereas the selection rate of the answers A and B that deny “Large text” is 60%. It exceeds the rate.
For this reason, even if the answers to the question (1) are collected in the answer C, there is a possibility that the modification of the processing program of the CAD device 1 is not in line with the student's request.

Therefore, in the second embodiment, when the selection rate of the answer having the largest selection number does not exceed the majority, the selection numbers of the answers A, B, and C are weighted without being aggregated to the answer having the largest selection number. To obtain the center of gravity (average answer) of the answers.
For example, when the number of answers A selected is “30”, the number of answers B selected is “30”, and the number of answers C selected is “40”, the center of the answer is located in the vicinity of the answer B (answer B A position slightly shifted to the answer A side), the answer of the question (1) is collected in the answer B.
In this case, the size of the character of the CAD operation description is not modified, and the size of the character is maintained.

  As apparent from the above, according to the second embodiment, since the questionnaire responses are aggregated in consideration of the balance of the answers in the questionnaire, the CAD apparatus 1 is more effective than the first embodiment. There is an effect that the demands and indications of students actually used can be appropriately reflected in the CAD device 1.

Embodiment 3 FIG.
FIG. 5 is a block diagram showing a CAD development apparatus according to Embodiment 3 of the present invention. In the figure, the same reference numerals as those in FIG.
The implementation status collection processing unit 21 of the CAD development apparatus 2 is composed of, for example, a semiconductor integrated circuit such as an MPU, and the practice period (field test) stored in the ASP server 3 via the network I / F 11. Implementation status). The network I / F 11 and the implementation status collection processing unit 21 constitute implementation status collection means.
The refurbishment processing unit 22 of the CAD development device 2 performs a process of refurbishing the processing program of the CAD device 1 according to the questionnaire responses aggregated by the response aggregation processing unit 13 in the same manner as the remediation processing unit 14 of FIG. At the same time, when the processing program or the like is modified, the processing program or the like of the CAD device 1 is modified in consideration of the implementation period of the exercise items collected by the implementation status collection processing unit 21. The repair processing unit 22 constitutes a repair means.

Next, the operation will be described.
When a university student operates the CAD device 1 and executes field test exercise items, the CAD device 1 generates CAD data and conducts a questionnaire, as in the first embodiment, The answer is transmitted to the CAD development device 2, but the execution period of the exercise item is transmitted to the ASP server 3.
When the ASP server 3 receives the execution period of the exercise item from the CAD device 1, the ASP server 3 obtains an average value of the execution period by a plurality of students and stores the average value of the execution period.
The implementation status collection processing unit 21 of the CAD development device 2 collects the average value of the implementation period stored in the ASP server 3 via the network I / F 11.

The refurbishment processing unit 22 of the CAD development apparatus 2 is configured such that when the response aggregation processing unit 13 aggregates questionnaire responses and the implementation status collection processing unit 21 collects the average value of the implementation period, the post-consolidation answer and the average value of the implementation period In response to this, processing for modifying the processing program of the CAD device 1 is executed.
Here, for example, it is assumed that “A. Complexity, B. Normal, C. Simple” is prepared as an answer to the question content “Is CAD operation complicated?”.
Further, if the answer to the question is answer A, the modification contents to reduce the CAD operation items, if the answer to the question is answer C, the modification contents to increase the CAD operation items, and if the answer to the question is answer B, It is assumed that contents for maintaining CAD operation items are prepared in advance.

For example, if the response after the aggregation by the response aggregation processing unit 13 is the response C, the modification processing unit 22 recognizes that the operation is simple and the CAD processing is performed according to the methods of the first and second embodiments. Renovation will increase the number of operation items.
However, if the average value of the implementation period collected by the implementation status collection processing unit 21 is longer than the implementation period assumed in advance, there is a high possibility that the operation of the CAD is confused. The CAD operation items are maintained without renovation to increase the operation items.
Therefore, even when the aggregated response is the response C, the refurbishment processing unit 22 performs renovation that increases the operation items of CAD only when the average value of the execution period is shorter than the presumed execution period. To.

On the other hand, if the answer after the aggregation by the answer aggregation processing unit 13 is the answer A, the modification processing unit 22 recognizes that the operation is complicated if the methods of the first and second embodiments are described above. Renovation will reduce the number of operation items.
However, if the average value of the implementation period collected by the implementation status collection processing unit 21 is shorter than the implementation period assumed in advance, there is a low possibility of being confused by the CAD operation. The CAD operation items are maintained without renovation to reduce the operation items.
Therefore, even when the response after aggregation is the answer A, the refurbishment processing unit 22 performs renovation that reduces the number of CAD operation items only when the average value of the execution period is longer than the expected execution period. To.

  As is apparent from the above, according to the third embodiment, the implementation status collection processing unit 21 that collects the average value of the exercise items performed by the students is provided, and the repair processing unit 22 is operated by the implementation status collection processing unit 21. Since the processing program of the CAD apparatus 1 is modified in consideration of the collected average value of the implementation period, the modification according to the implementation status of the student is achieved.
