Description

The present invention distributes questionnaire questions via a two-dimensional code to an answering terminal that can read the two-dimensional code, and uses a random number when selecting a question to generate a population for each question. In addition, the present invention relates to a technical field for constructing a system including an algorithm that equalizes the attributes of under statistically constant reliability, obtains a load on a server and a communication line, and changes a query transmission method according to the load value.

There is a questionnaire as one of the means for conducting customer research and marketing research. By investigating a user's opinion through a questionnaire, it is possible to acquire data for improving existing products and services or determining products and services to be newly developed. Previously, many questionnaire surveys were in the form of paper media, but in recent years, with the spread of mobile phones and personal computers, the cost of communications using communication means such as the Internet has been reduced. The questionnaire method using a computer has become common.

When paper media was used for the questionnaire, a large amount of manpower was required for distribution, collection, and tabulation. On the other hand, using a computer eliminates the hassle and only manages server computers. Questionnaire management is realized.

In a questionnaire using a computer, a server computer for generating a questionnaire question and distributing it to an answering terminal and receiving an answer result transmitted from the answering terminal and recording / statistically is first required. And as a terminal for an answer, the computer provided with the input means for a user to receive and display the question delivered from a server computer and to input an answer is required. Some terminals for answering use a dedicated terminal, while others use a personal computer or a mobile phone. In particular, when a mobile phone is used, there is an advantage that questionnaires can be distributed and answer results can be collected regardless of where the respondent is, and it is easy to conduct a large-scale survey.

An advantage of a questionnaire using a computer is that the contents of a question can be changed by each answering terminal. This operation can be automated by a program, and an operation of distributing different questions according to individual characteristics can be realized very easily as compared with a questionnaire using a paper medium.

In addition to this, an operation of changing the contents of a question to be distributed afterward depending on the answer result of a certain question can be automatically realized by a program in the case of a questionnaire using a computer.
JP 2007-102647 A

A questionnaire using a computer can deliver a large number of questions. However, if a large number of questions are delivered at once, the respondent's willingness to answer will be reduced, and the number of valid answers will decrease. Also, if the number of questions is reduced, the information obtained about the respondent's attributes decreases. In either case, there arises a problem that the amount of information related to answers decreases.

However, when a questionnaire composed of a small amount of questions is generated and a large amount of information is extracted from the questionnaire, a huge amount of answer samples are required, and access to the server computer becomes excessive.

Further, if a huge amount of samples are collected, it is not practical to require the respondent to register in advance. However, collecting the attributes of each respondent is extremely difficult without prior registration.

The present invention has been made in view of the above problems, and its purpose is to grasp the detailed attributes of respondents and generate statistics in a questionnaire system using a computer while generating a questionnaire consisting of a small number of questions. To create a questionnaire system.

In order to solve the above-mentioned problems, the invention of claim 1 in the present invention is connected to a server computer 1 having a server program for sending a questionnaire and receiving and recording a response to the questionnaire. A database 2 for accumulating information on the questionnaire, and a computer connected to the server computer 1 via communication means to receive a questionnaire, which is a server for displaying a questionnaire form, accepting questionnaire response input, and answering results A questionnaire statistical system comprising a response terminal 3 provided with a terminal program for transmission to the computer 1, wherein the server program determines a question content in the questionnaire using random numbers, and two or more steps Sending questions and receiving answers Flop and the survey statistics system characterized in that it comprises the step of recording the two or more answer information questions each in association with each other in the database 2.

The invention of claim 2 further includes a server computer 1 having a server program for transmitting a questionnaire and receiving and recording a response thereto, a database 2 connected to the server computer 1 and storing information related to the questionnaire, A computer that is connected to the server computer 1 via communication means and receives a questionnaire, and includes a terminal program that displays a questionnaire form, accepts a questionnaire response input, and transmits a response result to the server computer 1 And a means for transmitting the identification number 3A to the server computer 1 and having an identification number 3A that is unique to each terminal. The server program is provided in the questionnaire Determining the contents of the question using random numbers, receiving the identification number 3A, and associating the identification number 3A with an answer result and recording the result in the database 2. A questionnaire survey system is used.

The invention according to claim 3 is the questionnaire statistical system according to claim 1 or 2, wherein the server program further acquires a line occupancy ratio in the communication means and a processing capacity occupancy ratio in the server computer 1. And a questionnaire statistical system comprising a step of adding the line occupancy and the processing capacity occupancy as factors when determining the number and contents of the questions to be transmitted to the answering terminal 3 and the answering method. .

The invention according to claim 4 is the questionnaire statistical system according to any one of claims 1 to 4, wherein the server program further generates a two-dimensional code 7 and a questionnaire from the answering terminal 3 A step of transmitting a question in response to a transmission request, and a step of adding, as a factor, data transmitted in response to the transmission request when determining the number, contents, and answer method of the question to be transmitted to the answer terminal 3 Further comprises reading means for reading the two-dimensional code 7 and obtaining data encoded therein, and the terminal program further sends the transmission request to the server computer 1 based on the data obtained by the reading means. It is set as the questionnaire statistics system characterized by providing the step performed with respect to it.

Further, the invention of claim 5 is the questionnaire statistical system according to any one of claims 1 to 5, wherein the server program is further recorded in the database 2 which is already obtained answer data. An analysis step for statistically analyzing the data being included, and a step of adding the result obtained by the analysis step as a factor when determining the number of questions to be transmitted to the answering terminal 3, the contents, and the answering method Statistical system.

According to the first aspect of the present invention, the server program selects two or more questions by using a random number when determining the contents of the question to be transmitted to the answering terminal. At this time, the contents of the question delivered to each answering terminal are different. As for a single question, it is the same as extracting the target audience to be distributed randomly from the survey target population, and the target audience and the survey target population have a certain level of trust. The attributes can be considered equal under the degree / confidence interval. Therefore, by making the question delivered to each respondent different and determining the question using random numbers, the attributes of the population are estimated while keeping the number of questions delivered to each respondent small. It becomes possible. And the correlation which exists between the answers of each question can be calculated | required by making the number of the questions delivered to each answer terminal into two or more.

In the invention of claim 2, each reply terminal has a unique identification number, and the server computer obtains the identification number when sending the reply. As a result, the history information such as when and how to answer what question by each answering terminal is accumulated in the database 2. For example, when a mobile phone is used as the answering terminal, the attributes of the owner of the mobile phone can be analyzed. In this case, unlike the invention of claim 1, even if the number of questions delivered at one time is one, a correlation between the answers of the questions can be obtained. Therefore, the number of questions delivered at one time can be extremely small (at least one), and the possibility of damaging the respondents' willingness to answer can be minimized.

In the invention of claim 3, the server program can acquire the line occupation ratio in the communication means and the processing capacity occupation ratio in the server computer. For example, in Japan, there is almost no track record of a questionnaire server computer that can handle thousands of accesses per second. However, preparing a large number of questions in advance, distributing one or two of each question to each answering terminal, and estimating the correlation between each question with sufficient confidence, Distribution of a huge amount of questionnaires may be required. In such a case, if the line occupancy rate or the processing capability occupancy rate approaches the limit, the risk of the server computer going down increases.

In order to deal with such dangers, when setting question items, the load on the line and processing capacity in operations such as distribution of each question, reception of answers, and recording in a database are set in advance as numerical values. . Regarding the answer to the question, for example, the load value is set in advance in the two-choice type, the five-choice type, the free description type, or the like. Furthermore, when the above two types of occupancy rates are approaching the limit, a load value is set for the case where an error is delivered to the answering terminal without delivering the question. The question to be distributed to each answering terminal is determined in consideration of the numerical values set by these. Thereby, the buffer effect can be brought about with respect to the increase / decrease of the load with respect to a communication means and a server computer, and the management of a questionnaire can be stabilized.

In the invention of claim 4, it is possible to participate in the questionnaire by using a mobile phone or the like as the answering terminal and reading the two-dimensional code generated by the server program by the answering terminal. As an example of the effect, an example of a movie theater ticket will be described. The two-dimensional code issued by the server computer is printed on the movie theater admission ticket. Then, the two-dimensional code is read by a mobile phone (used as an answering terminal), and the data is transmitted to the server computer, whereby a questionnaire transmission request is made. As a result, movie theater visitors can participate in the questionnaire only by reading the two-dimensional code, and the server computer can automatically grasp which movie is viewed in which movie theater and in which screening schedule.

In the invention of claim 5, the server program statistically analyzes the answers made in the past, and determines the question to be delivered to the answering terminal from the result. Thereby, it is possible to increase a probability that a question with a small number of answers, which becomes a bottleneck in performing statistical analysis, is distributed. This makes it possible to collect data with high reliability even if the number of questions distributed at a time is small.

Embodiments of the invention will be described below.

As an embodiment of the present invention, a questionnaire method at an event venue will be described. In this embodiment, an event participant reads a two-dimensional code using a portable answering terminal, connects to a server computer using data encoded in the two-dimensional code, It is an Example regarding the questionnaire statistical system which performs reception and transmission of an answer.

First, a block diagram showing the configuration of the answering terminal 3 will be described with reference to FIG.

The answering terminal 3 is connected to the server computer 1 via the communication means 5 and can communicate with each other. When connecting, the network interface 340 is used to connect to the server computer 1 via the communication means 5.

If the Internet is used as the communication means 5, this embodiment can be easily realized. Communication means other than the Internet may be used.

The answering terminal 3 includes a photographing unit 311 and can photograph a still image or a moving image. The CPU 320 includes an imaging unit control unit 321 and controls the imaging unit 311 to perform an imaging operation. At this time, the holder 4 of the answering terminal 3 takes an image by operating the input unit 312.

Further, the CPU 320 includes a two-dimensional code decoding unit 322. The two-dimensional code decoding unit 322 recognizes whether or not the two-dimensional code is included in the still image or the moving image photographed by the photographing unit 311, and when the two-dimensional code is included, the two-dimensional code Is decoded and the encoded data is obtained.

Further, the CPU 320 includes a questionnaire transmission request unit 323. The questionnaire transmission request unit 323 connects to the server computer 1 based on the data obtained as a result of decoding the two-dimensional code by the two-dimensional code decoding unit 322, and makes a questionnaire transmission request. When connecting to the server computer 1, the identification number 3 A stored in the ROM unit 350 is transmitted to the server computer 1.

The server address 1A for connecting to the server computer 1 that is data recorded in the two-dimensional code may be in the URL format, or the server address 1A may be stored in the answering terminal 3 in advance. good.

When performing these processes by the CPU 320, the memory 330 is used as a temporary storage area.

The questionnaire in the questionnaire is transmitted from the server computer 1 to the answering terminal 3 in response to the questionnaire transmission request. The contents of the question are displayed on the display unit 313. The answer is made when the holder 4 performs an input operation using the input unit 312.

The storage unit 360 is a storage area in which information related to a question display style and information related to a question history can be stored. When displaying a question, HTML or XML may be used, or dedicated software for displaying may be used.

Such an answering terminal 3 can be easily realized by using a mobile phone as hardware and incorporating a program for realizing the above functions. In addition to a mobile phone, it may be a PDA, a mobile personal computer, a game machine, a digital camera, an electronic wallet, or any other computer.

Next, the network configuration in the present embodiment will be described with reference to FIG.

A plurality of server computers 1 that distribute questions and receive answers in questionnaires and answer terminals 3 that are terminals for answering questions are connected via communication means 5. Mutual communication is possible between the server computer 1 and the answering terminal 3. The operation of each answering terminal 3 is performed by each owner 4. There is a one-to-one correspondence between the answering terminal 3 and the holder 4. Therefore, an answer by the answering terminal 3 having a certain identification number 3A is an answer by the holder 4 corresponding thereto. Therefore, the expression “owner” in the present embodiment represents the target of the questionnaire.

The server computer 1 and the two-dimensional code display computer 8 are connected to each other via the communication means 5. The computer includes a display program as a program built in the two-dimensional code display computer 8 and controls the display of the two-dimensional code 7 on the display means 6.

The server computer 1 is connected to the database 2 and can read and rewrite data in the database 2.

As described above, the answering terminal 3 has means for reading the two-dimensional code (photographing and acquiring the resulting data, further decoding the data, and acquiring the resulting data). By this means, the two-dimensional code 7 can be read.

Next, a flowchart for carrying out the present invention will be described with reference to FIG. As depicted in FIG. 4, the steps assigned with the numbers S1000, S8000, and S3000 are mainly operated by the server computer 1, the two-dimensional code display computer 8, and the answering terminal 3, respectively. It is clear. The description of the operation subject that is obvious in each step is omitted.

First, the start input for starting operation with respect to the server computer 1 is made.

In step S1001, a two-dimensional code ID 7A is generated. This ID is a unique number for each two-dimensional code.

In step S1002, the data including the server address 1A for connecting to the server computer 1 via the communication means 5 and the two-dimensional code ID 7A is encoded, and the two-dimensional code 7 is generated.

In step S1003, the two-dimensional code 7 generated in the previous step is transmitted to the two-dimensional code display computer 8.

In step S8001, the two-dimensional code 7 transmitted from the server computer 1 is received. At this time, the data before encoding may be received and encoded by the two-dimensional code display computer 8.

In step S8002, the two-dimensional code 7 is displayed on the display device 6.

In step S8003, an interrupt instruction for terminating the display of the two-dimensional code 7 is permitted.

In step S8004, the two-dimensional code 7 displayed on the display device 6 is controlled as a moving image.

Here, the reason why the two-dimensional code 7 is a moving image is that it can be read from anywhere in the event venue. For example, when the two-dimensional code 7 is a moving image whose size changes with the passage of time, it can be read at a position close to the display device 6 when displayed small, and from the display device 6 when displayed large. It can be read at a far position.

The processing in step S8004 ends after a certain time has elapsed or when more than a certain number of responses have been collected.

Next, in order to read the two-dimensional code 7 displayed on the display device 6, the holder 4 performs an input operation for starting reading on the answering terminal 3. Thereby, step S3001 is started.

In step S3001, the two-dimensional code 7 is read. As a result of reading, the two-dimensional code ID 7A, the server address 1A, and other information are obtained.

In step S3002, connection is made to the address on the network indicated by the server address 1A. As a result, the answering terminal 3 is connected to the server computer 1. When the connection is established, the reply terminal 3 transmits the two-dimensional code ID 7A to the server computer 1. Here, the identification number 3A is also transmitted when the two-dimensional code ID 7A is transmitted. This corresponds to a questionnaire transmission request.

The server computer 1 receives the questionnaire transmission request in S1004. Next, the line occupancy ratio in the communication means and the processing capacity occupancy ratio in the server computer 1 are acquired, and how much each has room is calculated. Details of branching by occupation ratio will be described in a fourth embodiment.

In addition, it is effective to improve the willingness of the answer of the holder 4 as the answer format in the present embodiment, but a format for selecting from three or more options and a format for free description are available. Very good.

When the process proceeds to step S1005 after step S1004, error information is transmitted to the answering terminal 3.

Subsequently, the reply terminal 3 receives the error information in step S3003, displays that an error has occurred and cannot participate in the questionnaire, and the process ends.

When the process proceeds to step S1006 after step S1004, a question to be transmitted to the answering terminal 3 is determined.

Subsequently, in step S1007, the question is transmitted to the answering terminal 3.

The answering terminal 3 receives and displays the question in step S3004.

In step S3005, an input of an answer to the question is accepted.

In step S3006, the answer result is transmitted to the server computer 1.
The server computer 1 records the answer result in the database 2 in step S1008.

In step S1009, the reply terminal 3 is notified that the questionnaire has ended. A lottery may be performed at this time.

The answering terminal 3 displays that the questionnaire is finished in step S3008, and the process is finished.

When a questionnaire is transmitted to the answering terminal 3, as a transmission method thereof, a voice barcode may be used, or distribution may be performed by mail. Further, wireless communication or infrared communication using WI-FI or BLOUTOOTH may be used. When such a questionnaire transmission method is used, there is an advantage that it is easier to control the timing of transmitting the questionnaire to the survey target person on the server computer 1 side than when the questionnaire transmission request is transmitted. However, in the case of mail distribution, pre-registration of the mail address is required.

When sending a questionnaire to the answering terminal 3 or sending a lottery result, an advertisement may be displayed on the answering terminal 3. In the case of displaying an advertisement, it is possible to distribute an advertisement that seems to have the highest advertising effect by analyzing the past answer tendency with respect to the answering terminal 3.

Information exchange between the server computer 1 and the answering terminal 3 is preferably performed using an encryption technique. For example, consider a case in which a URL is included in text data encoded in a two-dimensional code and a questionnaire transmission request is made by connecting to the URL. In this case, a “question mark” is added to the end of the URL, and the two-dimensional code ID 7A is included in the subsequent character string. If the holder 4 can freely generate a URL including the two-dimensional code ID 7A, the server computer 1 can be accessed illegally. Unless such unauthorized access is prevented, the reliability of the system decreases.

For example, as a preventive measure, there is a method of encoding the two-dimensional code 7 after encrypting the two-dimensional code ID 7A. In order to further enhance security, different keys are generated at the time of encryption of each two-dimensional code ID, a key number is assigned to each key, and stored only in the server computer 1. Then, the two-dimensional code ID 7A is encrypted, and the data with the key number corresponding to the key used for encryption is further encrypted. Then, the URL to which the encrypted data is added is encoded into a two-dimensional code. As a result, when the holder 4 illegally modifies the encrypted part at the end of the URL, the decryption becomes impossible, so that it can be understood that the illegal modification has been made. As a result, unauthorized access to the server computer 1 can be determined and rejected.

An embodiment in which a two-dimensional code is printed on a ticket in a movie theater and a questionnaire in the movie theater is performed will be described.

The network configuration of the entire system will be described with reference to FIG.

The server computer 1 is connected to a plurality of answer terminals 3 via communication means 5. The response terminal 3 and the holder 4 have a one-to-one correspondence. Therefore, each owner 4 is a survey target person in the questionnaire. That is, the owner 4 is a visitor who watches a movie, and the answer is an answer by each viewer.

The server computer 1 and the printer server computer 9 are connected via communication means.

The printer server computer 9 is connected to the printer 10 and includes a print program for sending a print operation command to the printer 10.

The printer 10 includes means for printing the ticket 11. Note that a two-dimensional code 7 is printed on the ticket 11. By reading the two-dimensional code 7 by the answering terminal 3, the holder 4 can participate in the questionnaire.

The ticket consists of two stubs, and the two-dimensional code 7 is printed on the stub that is not collected when entering the hall. The holder 4 who has finished watching the movie uses the answering terminal 3 to read the two-dimensional code 7 and participates in the questionnaire.

The block diagram showing the configuration of the answering terminal 3 in this embodiment has the configuration shown in FIG. 2 as in the first embodiment. Similar to the first embodiment, such an answering terminal 3 can be easily realized by using a mobile phone as hardware and incorporating a program for realizing the above functions. In addition to a mobile phone, it may be a PDA, a mobile personal computer, a game machine, a digital camera, an electronic wallet, or any other computer.

Next, a flowchart showing the execution procedure of the present embodiment will be described with reference to FIGS. The data structure in the database 2 is shown in FIG. Note that the database 2 has a relational structure, and the description of PK in FIG. 10 indicates PRIMARY KEY (primary key), and the description of FK indicates FOREIGN KEY (foreign key). Elements with numbers in the 200s represent data tables.

Similar to the first embodiment, the description of the execution of each step is omitted when the operation subject is clear.

The operation is started when a start input of the program is given to the server computer 1.

In step S1101, a new record is generated in the movie project 201. The movie plan 201 is a data table that defines combinations of the two-dimensional code 202, the lottery 203, the movie theater 204, and the movie 205 (refer to FIGS. 8 and 9 for the description of the database 2).

In step S1102, a record generated with the record generated in the previous step is generated. In other words, settings regarding which movie is shown in which movie theater and what question is distributed along with it, the display size of the two-dimensional code 7 and the like are recorded as a record in the movie theater planning 201.

The question set statement 207 defines the association between the movie theater plan 201 and the question 206. That is, when selecting a question by a questionnaire for the movie theater plan 201, one of the questions defined by the question set description 207 is selected.

Here, the structure of the database 2 will be described with reference to FIG. FIG. 9 shows an example of a table that can be created from the database structure shown in FIG. In the description in this paragraph, the number or character string in “” is irrelevant to the reference numeral on the drawing, and indicates a value recorded in the database. According to the example shown here, the question codes “1” to “4” are “Is it interesting”, “Do you recommend it to others”, “Do you want to see it again” and “Do you recommend it to others” The question “Is the screening time appropriate?” Corresponds to each question. In addition, the movie theater project indicated by the movie theater code “1” indicates that the movie “Story I” indicated by the movie code “9” will be screened in the movie theater “Umeda” indicated by the movie theater code “20”. Show. Further, the question detail code “1” represents the association between the question “Is it interesting” indicated by the question code “1” and the movie theater plan indicated by the movie theater code “1”?

Subsequently, in step S1103, the two-dimensional code ID 7A is set. The two-dimensional code ID 7A is substituted for the two-dimensional code ID in the data table two-dimensional code 202 to generate a record.

The execution order of these steps S1101 to S1103 is arbitrary.

In step 1104, the two-dimensional code 7 is generated from the two-dimensional code ID 7A and the server address 1A.

In step S 1105, the two-dimensional code 7 and data indicating the required number of prints are transmitted to the printer server computer 9.

In step S9101, the printer server computer 9 receives the two-dimensional code 7 and data indicating the number of printed sheets.

In step S9102, the printer 10 is used to print the required number of tickets 11.

The ticket 11 printed by the procedure so far is used as a movie admission ticket. From the two-dimensional code ID 7 </ b> A in the two-dimensional code 7 printed on the ticket 11, it is possible to trace information on a movie to be screened and a movie theater on the database 2.

Next, the holder 4 performs an input operation on the answering terminal 3 and reads the two-dimensional code 7 printed on the ticket 11 to execute step S3111. As a result of reading here, a server address 1A and a two-dimensional code ID 7A are obtained.

In step S3112, the server address 1A obtained in the previous step is used to connect to the server computer 1, and the two-dimensional code ID 7A is transmitted, the identification number 3A is transmitted, and a questionnaire transmission request is made.

The server computer 1 receives a questionnaire transmission request in step S1111. Based on the two-dimensional code ID 7A acquired there, the movie ticket from which the holder 4 made the transmission request is acquired. Here, the movie screening schedule corresponding to the two-dimensional code 7 is matched with the time when the transmission request is made. That is, it is grasped whether the transmission request is made before the start of the movie, during the movie, or after the movie is finished. If it has been done before the start of the screening, in step S1114, the reply terminal 3 is notified that it can only participate in the questionnaire after the end of the screening of the movie. If a transmission request is made during the screening, it can be notified in step S1114 that using the answering terminal 3 during the screening is a violation of manners. As described above, when the reply terminal 3 is notified that the screening is not finished, the reply terminal 3 displays a warning in step S3113, and the process ends. If the time when the transmission request is made is after the movie, the process proceeds to step S1113.

When the process proceeds to step S1113, a question to be transmitted to the answering terminal 3 is determined in this step. This is selected using a random number from the questions 206 belonging to the question set 207 associated with the two-dimensional code ID 7A printed on the ticket. The number of questions to be transmitted is set in advance.

Next, in step S3114, a question is displayed.

In step S3115, an input of an answer by the holder 4 is accepted.

In step S3116, the input result of the answer in the previous step is transmitted to the server computer 1.

The server computer 1 receives the answer result in step S1116.

In step S1117, the answer result is recorded in the database 2. At this time, a record is added to the data table answering terminal 209 using the identification number 3A as a primary key. If a record having the identification number 3A as a primary key already exists, no record is added. The answer details 208 define the association of which answering terminal answered which question in which movie.

In addition, when a record by the answer terminal 3 having a certain identification number 3A and the question set detail code already exists on the answer detail 208 and it is requested to overwrite the same record again, the data is not overwritten. Notify the answering terminal that the answer has been made.

A lottery is performed in step S1118. When this lottery is won, the holder 4 can obtain prizes and money. The lottery is very effective for improving the willingness of the holder 4 to participate in the questionnaire.

In step S1119, the lottery result in the previous step is transmitted to the answering terminal 3.

The answering terminal 3 displays the lottery result in step S3117.

In the present embodiment, a product comprising a container 12 is assumed, a two-dimensional code is attached to the product, and the questionnaire for the product is implemented by reading the two-dimensional code with an answering terminal.

First, the configuration of the entire system will be described with reference to FIG.

The server computer 1 is a computer that generates a two-dimensional code and updates the database 2. Server computer 1 is connected to database 2. The database 2 stores data on questionnaires, two-dimensional codes, and answering terminals in this system. The manufacturing server computer 13 is a computer that manages information related to attachment of the two-dimensional code 7 and shipment of the product when the product including the container 12 is manufactured. The manufacturing server computer 13 is connected to the printer 10 and has a function of controlling print output in the printer 10.

The answering terminal 3 is a computer connected to the server computer 1 via communication means. The internal structure of the answering terminal 3 is the same as that shown in the first embodiment (see FIG. 2). The answering terminal 3 includes means for reading the two-dimensional code 7 and transmitting a questionnaire transmission request based on the result to the server computer 1. The server computer 1 receives the questionnaire transmission request and distributes the question to the answering terminal 3. There is a one-to-one correspondence between the answering terminal 3 and the holder 4. Therefore, when participation in the questionnaire is made by reading the two-dimensional code 7 by the answering terminal 3, the answer is the answer by the holder 4. That is, the questionnaire survey in this case is an opinion survey with respect to the owner 4 with respect to the product comprising the container 12.

Next, referring to FIG. 14, an execution procedure until the product with the two-dimensional code 7 attached is shipped will be described. The omission of the description of the execution subject is the same as in the first and second embodiments.

The program is started in response to the start input.

In step S1201, a new record is generated in the product plan 250. Here, the product plan 250 defines how the lottery 203, the two-dimensional code 202, and the product 251 are associated (see FIG. 13 for the structure of the database 2). In other words, information such as what lottery is performed for what two-dimensional code and the two-dimensional code is attached to which product is provided as a record.

In step S1202, a record accompanying the record generated in the previous step is generated. Where

In step S1203, the two-dimensional code ID 7A is set.

The execution procedure of steps S1202 to S1203 may be arbitrary.

In step S1204, the two-dimensional code 7 is generated from the two-dimensional code 7A and the server address 1A.

In step S 1205, the two-dimensional code 7 and data indicating the required number of prints are transmitted to the manufacturing server computer 11.

In step S 13201, the manufacturing server computer 13 receives the two-dimensional code 7 and data indicating the number of printed sheets.

In step S13102, the two-dimensional code 7 is printed using the printer 10.

In step S13104, an input indicating that the two-dimensional code is attached to the inner surface of the container 12 is received.

In step S13103, the input content made in the previous step is recorded.

In step S13105, an input indicating shipment of the container 12 is received.

In step S13106, the input contents made in the previous step are recorded.

By the steps up to here, the commodity consisting of the container 12 and attached with the two-dimensional code 7 is shipped. In this case, the shipping time is also recorded in association with the two-dimensional code ID 7A.

Next, an execution procedure after the answering terminal 3 reads the two-dimensional code 7 will be described with reference to FIG.

When the holder 4 performs an input operation on the answering terminal 3, step S3211 is executed. At this time, the answering terminal 3 reads the two-dimensional code 7 in step S3211. In addition, since the container 12 is sealed and the two-dimensional code 7 is attached to the inside thereof, the two-dimensional code 7 cannot be read without performing an opening operation.

In step S3212, a questionnaire transmission request is made to the server computer 1 based on the reading result in the previous step.

In step S1211, the server computer 1 receives the questionnaire transmission request. When the answering terminal 3 is connected to the server computer 1, the identification number 3A can be acquired from the server computer 1. Furthermore, the server computer 1 can also acquire the time. Since the container 12 has a structure in which the two-dimensional code 7 cannot be read unless the container 12 is opened, the time acquired by the server computer 1 at this time indicates the opening time of the container 12. Further, when food is contained in the container 12, a question for investigating the evaluation of the food can be set as the content of the question in the questionnaire.

In step S1212, the line occupation ratio in the communication unit 5 and the processing capacity occupation ratio in the server computer 1 are acquired. If these occupancy rates have no allowance, the process proceeds to step S1214. If there is a margin, the process proceeds to step S1213. Details of the branching using the occupation rate will be described in the fourth embodiment.

In step S1212, it is determined whether or not the answer is the first time, and the process branches. When the answering terminal 3 answers the question of the questionnaire read with respect to a certain two-dimensional code 7, the result is recorded in the data table answer details 208. By examining this record, the same two-dimensional code 7 It is possible to determine whether or not an answer from the same answering terminal 3 has already been made.

In step S1214, the reply terminal 3 is notified that it cannot participate in the questionnaire.

In step S3213, when the notification that the user cannot participate in the questionnaire is received from the server computer 1, the answering terminal 3 displays a warning and ends the process.

In step S1215, a question to be transmitted to the answering terminal 3 is determined.

In this step, for example, when one question is transmitted from 10 questions, it is checked by accessing the database 2 how many answers are recorded for each question. And it correct | amends so that the frequency with which the question with few number of answers recorded most is sent to the reply terminal 3 increases. If two questions are sent out of 10 questions, there are 45 combinations for selecting the two questions. Of these 45 combinations, corrections are made so that the frequency with which combinations with few answers obtained in the past are sent to the answering terminal 3 is increased.

In step S1216, the question is transmitted to the answering terminal 3.

The answering terminal 3 receives the question in step S3214 and displays the content.

In step S3215, an answer to the question is received.

In step S3216, the answer result is transmitted to the server computer 1.

In step S1217, the server computer 1 receives the answer result.

In step S1218, the response result received in the previous step is recorded in the database 2.

A lottery is carried out in step S1219.

In step S1220, the lottery result is transmitted to the answering terminal 3.

In step S3217, the answering terminal 3 receives the lottery result and displays the content. Thus, the process ends.

Further, when there are a plurality of questions, if one answer is transmitted to the server computer 1 one by one, the processing load on the communication line and the server computer 1 increases. Therefore, data regarding answers to a plurality of questions may be transmitted to the server computer 1 at once. For this function, dedicated software may be incorporated into the answering terminal 3, or a program in a script language may be sent to the answering terminal 3 when sending a question from the server computer 1.

In this embodiment, the questionnaire is started when the answering terminal 3 reads the two-dimensional code 7 and requests the server computer 1 to send a questionnaire. The role of the two-dimensional code 7 is replaced by RFID or the like. You can also. In this case, the answering terminal 3 is configured to have an RFID reading function.

The example given here represents an example of the embodiment of the present invention, and the present invention is not limited to the example given here.

A method for determining a question in a questionnaire using the line occupation rate in the communication means 5 and the processing capability occupation rate in the server computer 1 will be described.

A method of dealing with each occupation rate will be described with reference to FIG. A, B, C, and D respectively represent four categories according to the level of processing capacity occupation and the level of line occupation. In the following description, the high occupation rate exceeds a certain reference value, and if a normal operation is performed, the processing capacity of the communication line and the server computer 1 is not sufficient, and the operation becomes extremely unstable. Represents a state. A low occupancy rate is a state where normal operation is possible. A represents a state in which the processing capacity occupation ratio is high and the line occupation ratio is also high. In this state, no question is transmitted. B represents a case where the processing capacity occupation ratio is high and the line occupation ratio is low. In this case, the question is not transmitted at all. C indicates a state in which both occupancy rates are low. In this case, normal question transmission is performed. D represents a state in which the line occupation ratio is high but the processing capacity occupation ratio is low. Processing in this case will be described in the following paragraphs.

In the database 2, there is a data table having a question code as a primary key. For each question, as shown in FIG. 16, “transmission load” indicating the load on the line when transmitting from the server computer 1 to the answering terminal 3, and the answer line sent from the answering terminal 3 to the server computer 1 “Reception load” indicating the load on the response, “Reply time” indicating the average value of the time required from the transmission of the question to reception of the response, and “Standard deviation” indicating the variation of the response time are recorded. The values of the reply time and the standard deviation are corrected each time a question is transmitted and a reply is received. When the answer format is a descriptive formula, the load on the line when the answer is transmitted to the server computer 1 with the maximum number of characters is the “reception load”.

Next, description will be made with reference to FIG. The load value in FIG. 18 represents the load value for the communication line. Assume that the server computer 1 receives a questionnaire transmission request at a certain time T0. Then, when a question to be transmitted is determined, a time obtained by adding a reply time corresponding to the question to T0 is defined as T1. Here, the time distribution of the expected value of the load given to the line by the answer corresponding to the question is calculated. It is assumed that this distribution is a normal distribution centered on T1. This probability distribution becomes a value less than 1 when the entire range is integrated. This value represents the rate at which answers are returned when a question is sent. If the answer is 100%, the integrated value is 1. Also, the expected value of the load on the line by receiving the answer at each time is added to a variable array (referred to as a load variable array for convenience of explanation) representing the load value corresponding to each time. In this case, only the range where the magnitude (difference) of the expected value to be added exceeds the preset threshold TH0 is added. When the value of the variable included in the load variable array exceeds the threshold value TH1, the transmission question is changed to one having a small reception load, and the load variable array is calculated again. When there is no question that can prevent the value of the variable included in the load variable array from exceeding the threshold value TH1, the question is not transmitted to the answering terminal 3.

TH1 is set with a certain margin with respect to a load value that causes the communication line to go down when TH1 is exceeded.

By using the system in the present invention, it is possible to track the behavior of the holder 4 who has the answering terminal 3 having a certain identification number 3A. This is because the history is accumulated in the database 2 when the answering terminal 3 reads the two-dimensional code 7 according to the present invention. For example, by providing the database 2 with information related to the region where the product is sold in association with the product to which the two-dimensional code 7 is attached, it is also possible to grasp the history regarding the movement of the answering terminal 3 between regions. . This may be configured such that the answering terminal 3 has a GPS function and the server computer 1 side can acquire the position information of the answering terminal 3 when connecting to the server computer 1. Furthermore, by acquiring location information, it is possible to distribute advertisements for facilities in the vicinity.

Further, as a method for grasping the history regarding movement between regions, the two-dimensional code 7 according to the present invention may be printed on a ticket for transportation. By reading this two-dimensional code 7 at the answering terminal 3 and answering the questionnaire, a system for giving the carrier 4 mileage enough to correspond to the moving section by ticket or giving points by other point services It can also be constructed. Further, the point service in this case is not limited to a ticket for transportation, but can be realized by attaching the two-dimensional code 7 to a general product.

For example, when a questionnaire survey is conducted with a two-dimensional code 7 according to the present invention attached to a certain food product, the weather at the time when the answer result is sent and the answer result in the area where the answer result is sent are matched. It is good also as a structure. In this case, it is possible to investigate how the questionnaire survey result for a certain food changes depending on the weather and what correlation there is with the weather.

The two-dimensional code 7 according to the present invention can be attached to a product lent to the holder 4 in a rental format. For example, when renting a video product using DVD media, the two-dimensional code 7 according to the present invention is displayed as image data or moving image data at the end of the video. When the holder 4 reads the two-dimensional code 7 using the answering terminal 3 and participates in the questionnaire, the questionnaire is a questionnaire survey for the video.
