DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, the present embodiment will be described with reference to the drawings.

[0016] 1. Survey feature The questionnaire system according to this embodiment provides a function for conducting a questionnaire for users (hereinafter, simply referred to as a "questionnaire function.") Fig. 1 is a conceptual diagram for explaining the basic functionality of the questionnaire function.

[0017] In this embodiment, the process relating to the questionnaire function is executed by the server 100. The server 100 is communicably connected to a user terminal operated by a user.

[0018] In the survey function, users include a user 1 who conducts the survey (hereinafter referred to as "survey user 1") and a user 2 who is the subject of the survey (hereinafter referred to as "target user 2"). Here, it is generally assumed that there are multiple target users 2 for one survey. FIG. 1 shows a case where there are three target users 2.

[0019] 1 also shows, as user terminals, a user terminal 200a operated by a survey user 1 and a user terminal 200b operated by a target user 2. The user terminal 200a has an HMI (Human Machine Interface) function for the survey user 1. For example, the user terminal 200a has an input device (keyboard, switch, touch panel, etc.) that accepts input from the survey user 1 to the server 100, and a display that displays the output of the server 100 to the survey user 1. Similarly, the user terminal 200b has an HMI function for the target user 2.

[0020] The user terminal according to the present embodiment may be a dedicated terminal for the questionnaire system, or may be a computer that functions as a user terminal on a specific application. For example, the user terminal may be a personal computer, tablet, smartphone, etc. on which a specific application is installed.

[0021] In the survey function, first, the server 100 acquires information (survey information) about a survey that the investigating user 1 is going to take from the user terminal 200a. Here, the investigating user 1 inputs the survey information by operating the user terminal 200a.

[0022] Next, the server 100 generates a questionnaire based on the questionnaire information and transmits the generated questionnaire to the user terminal 200b. The user terminal 200b accepts the response from the target user 2 to the received questionnaire and transmits the accepted response to the server 100. Here, the target user 2 responds to the questionnaire by operating the user terminal 200b.

[0023] The server 100 then transmits the received answers to the user terminal 200a as the survey results. The survey user 1 checks the survey results by operating the user terminal 200a.

[0024] The questionnaire system according to this embodiment relates to a questionnaire system that provides such basic functions.

[0025] 2. Description of the assignment Examples of the survey that the research user 1 intends to conduct include a survey of users who have purchased a product or introduced a service, a survey of users who have participated in a particular event (an exhibition, a convention, etc.), a survey of users who have become product monitors, etc. Examples of the research user 1 include product or service developers, event organizers, product manufacturers, etc. For example, the research user 1 may intend to conduct a survey using the survey function as an evaluation of test marketing or demonstration experiments of a product.

[0026] When conducting such a survey, the survey user 1 is expected to want to obtain more information from the survey responses. For example, in a survey of users who have purchased a product, the survey user 1 is expected to want to obtain from the survey responses sufficient information about "when and what actions" the target user 2 took from the time he or she became aware of the product until the time he or she purchased it. However, when trying to obtain such a large amount of information from one survey, the survey will end up being composed of a huge number of questions that need to be confirmed one by one. If the number of questions in the survey becomes huge, the target user 2 will find it troublesome to answer the survey, resulting in a decrease in the survey response rate. In particular, the fact that the survey contains many questions that are unrelated to the user himself or herself is a factor that reduces the survey response rate.

[0027] Thus, the survey function provided by the survey system is required to improve the survey response rate and obtain more meaningful responses.

[0028] 3. Survey system The configuration of the questionnaire system according to this embodiment will be described below. Fig. 2 is a block diagram showing an example of the configuration of the questionnaire system 10 according to this embodiment.

[0029] In the questionnaire system 10, the server 100 is communicatively connected to one or more user terminals 200 (hereinafter simply referred to as "user terminals 200") and a monitoring system 300. For example, the server 100 is connected to the user terminals 200 and the monitoring system 300 via the Internet. In this case, the server 100 is typically a computer accessible via the Internet.

[0030] In this embodiment, the user terminal 200 is configured to transmit information that can be acquired by the functions of the mounted device or the application (hereinafter, referred to as "user terminal information") to the server 100. Examples of the user terminal information include location information acquired by a GNSS receiver, operation information about an operation performed by a user, travel route information acquired by a map application, payment information about a payment performed on a payment application, information about a site viewed in a browser, and the like. The user terminal information transmitted by the user terminal 200 may be suitably determined according to the form of the behavior information D12 described later. The user terminal 200 may also be configured to be able to set the user terminal information to be transmitted to the server 100 by a user operation. For example, the user terminal 200 may be configured to be able to set the user terminal information to be transmitted to the server 100 by a user operation.

[0031] The monitoring system 300 is a system that monitors a user and detects information about the user. For example, the monitoring system 300 is composed of a camera, a biosensor, a security gate, a card reader, and the like. The monitoring system 300 transmits the detected information to the server 100. Examples of the detected information include information on the user's movement line, biosensor information, and a log of entry and exit to a specified area. The configuration of the monitoring system 300 may be appropriately determined according to the behavior information D12 described later.

[0032] The server 100 includes one or more processors 110 (hereinafter simply referred to as "processor 110") and one or more storage devices (hereinafter simply referred to as "storage device 120"). The processor 110 executes various processes. The processor 110 may be configured, for example, as a central processing unit (CPU) including an arithmetic unit, a register, and the like. The storage device 120 is coupled to the processor 110 and stores various information required for the processor 110 to execute the processes. The storage device 120 may be configured, for example, as a recording medium such as a read only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), or a solid state drive (SSD).

[0033] The storage device 120 stores a computer program 121, a user database D10, and a question database D20.

[0034] The computer program 121 is made up of a plurality of instructions 122 and is stored in a computer-readable recording medium. The processor 110 operates in accordance with the plurality of instructions 122, thereby realizing the execution of various processes by the processor 110.

[0035] The user database D10 manages various data for each user. For example, the user database D10 manages data by linking it to a user ID that identifies each user. The data managed by the user database D10 includes attribute information D11 and behavior information D12.

[0036] The attribute information D11 manages the attributes (age, sex, occupation, etc.) of each user. The attribute information D11 may be configured to be updatable by each user. For example, each user transmits attribute information to the server 100 by operating the user terminal 200. Then, the processor 110 updates the attribute information D11 according to the attribute information for each user received by the server 100.

[0037] The behavior information D12 is stored in the storage device 120 by a process executed by the processor 110. The processor 110 acquires the behavior information D12 of each user from the information received by the server 100, and stores it in the storage device 120.

[0038] FIG. 3 shows an example of behavioral information D12 managed by the user database D10. In particular, FIG. 3 shows a history of behavioral information D12 for a certain user (user ID: 1111). The behavioral information D12 shown in FIG. 3 is, for example, behavioral information D12 acquired for a user living in a specific area. In this case, the monitoring system 300 is, for example, a camera or a security system installed in a facility or a path in the specific area. The processor 110 can acquire the behavioral information D12 from the detection information transmitted by the monitoring system 300.

[0039] For example, the monitoring system 300 includes an entrance / exit gate installed at an exhibition held in a specific area, and transmits the matching results of a user who has passed through the entrance / exit gate (for example, a user ID matched by face recognition or fingerprint recognition) as detection information to the server 100. Then, from the matching results, the processor 110 obtains "entered the exhibition" and "left the exhibition" as behavior information D12 for a certain user.

[0040] For example, the monitoring system 300 includes multiple cameras that capture the situation at an exhibition, and transmits image recognition results (e.g., information on the movement of each user using object tracking technology) of images captured by the multiple cameras to the server 100 as detection information. Then, from the image recognition results, the processor 110 obtains "visited the booth of product A at the exhibition" and "visited the booth of product B at the exhibition" as behavior information D12 for a certain user. Alternatively, the processor 110 may be configured to obtain such behavior information D12 from the position information of the user terminal 200.

[0041] Furthermore, the processor 110 can acquire the behavior information D12 from the user terminal information transmitted by the user terminal 200.

[0042] For example, the user terminal 200 is configured to transmit web tracking information as user terminal information to the server 100. From the web tracking information, the processor 110 obtains, as behavioral information D12 for a certain user, "checked the website for product A," "checked an advertisement for a demonstration experiment of product A," "applied to participate in the demonstration experiment of product A," and "submitted an evaluation of the demonstration experiment of product A as 'satisfactory'."

[0043] For example, the user terminal 200 is configured to transmit the usage status of the application to the server 100 as user terminal information. From the usage status of the application, the processor 110 acquires "connected with the inventor of product A on SNS" as behavioral information D12 for a certain user.

[0044] Also, for example, the user terminal 200 is configured to transmit payment information as user terminal information to the server 100. Then, from the payment information, the processor 110 obtains "Product A purchased on an EC site" as behavior information D12 for a certain user.

[0045] In this way, the behavior information D12 is stored in the storage device 120 as the user database D10 by the process executed by the processor 110. The processor 110 may be configured to acquire the behavior information D12 only from users who satisfy a predetermined gaze condition. Examples of the predetermined gaze condition include entering a specific area, agreeing to the acquisition of the behavior information D12, and agreeing to participate in answering a questionnaire. By adopting such a configuration, it is possible to take into consideration the user's intention regarding the acquisition of the behavior information D12.

[0046] Furthermore, the processor 110 may be configured to terminate acquisition of the behavior information D12 for a user who satisfies a predetermined release condition, such as leaving a specific area or purchasing a specific product.

[0047] Referring again to FIG. 2, the question database D20 manages question items for each survey that the survey user 1 intends to conduct. FIG. 4 shows an example of question items managed by the question database D20. As shown in FIG. 4, the survey that the survey user 1 intends to conduct is a survey (Product A Purchaser Survey) intended for users who have purchased Product A as target users 2. In FIG. 4, the titles of questions are shown as question items for the "Product A Purchaser Survey." The question items managed by the question database D20 may further include information on the answer format (multiple choice, free description, etc.) and options.

[0048] The question database D20 may be configured to be updatable by the survey user 1. For example, the survey user 1 transmits information on the designation of a survey to be conducted and question items to the server 100 as survey information. Then, the processor 110 updates the question database D20 according to the survey information received by the server 100.

[0049] As described above, the questionnaire system 10 according to the present embodiment is configured.

[0050] 4. Processing The processor 110 according to this embodiment executes a process (hereinafter simply referred to as the "survey generation process") to generate a survey to be presented to the target user 2 when the target user 2 is specified for any of the surveys managed by the question database D20.

[0051] Here, the target user 2 is specified, for example, by the survey user 1. For example, the survey user 1 specifies the attributes of a user to be the target user 2 for the survey to be conducted by operating the user terminal 200. In this case, the processor 110 refers to the attribute information D11 and specifies a user who matches the specified attributes as the target user 2. Alternatively, the survey user 1 may directly specify a user to be the target user 2 by a user ID or the like.

[0052] Furthermore, in this embodiment, the survey user 1 can also specify the behavior of the user who is the target user 2. For example, when the survey user 1 is going to conduct a survey of a user who has purchased a certain product A or a user who has introduced a certain service B as the target user 2, the survey user 1 can specify "purchase product A" or "introduce service B" as the behavior of the user who is the target user 2. Also, for example, when the survey user 1 is going to conduct a survey of a user who has visited a certain exhibition X as the target user 2, the survey user 1 can specify "enter exhibition X" as the behavior of the user who is the target user 2. In such a case, the processor 110 refers to the behavior information D12 and specifies a user who matches the specified behavior as the target user 2. Furthermore, the user behavior specified by the survey user 1 may include the date and time when the behavior information D12 is acquired and the area.

[0053] Alternatively, the question database D20 may be configured to manage the behavior of a user who is to be a target user 2 (hereinafter referred to as a "trigger behavior") for each questionnaire. Then, the processor 110 may be configured to designate a user who has performed a trigger behavior for each questionnaire as a target user 2 for each questionnaire based on the behavior information D12. In this case, the processor 110 may be configured to execute a questionnaire generation process for the designated target user 2 each time a user who has performed a trigger behavior for any questionnaire is designated as a target user 2.

[0054] For example, a trigger action for the "Survey for Product A Purchasers" shown in Fig. 4 is "Purchase Product A". In this case, when each user performs the action of "Purchase Product A", the user is designated as a target user 2 of the "Survey for Product A Purchasers". Then, processor 110 executes a survey generation process for the "Survey for Product A Purchasers".

[0055] Other examples of trigger actions include leaving a particular area (an exhibition, a shopping mall, an administrative district, etc.), receiving a particular service, participating in a particular event, etc. These trigger actions may be determined according to the survey to be conducted.

[0056] By adopting such a configuration, it is possible to configure the survey system 10 that automatically specifies the target user 2 and transmits the survey according to the behavior information D12 and the question database D20. As a result, it is possible to improve the efficiency of conducting the survey.

[0057] The processing executed by the processor 110 will now be described.

[0058] In the questionnaire generation process, the processor 110 sets one or more question items (hereinafter referred to as "questionnaire items") that constitute the questionnaire based on the history of the behavioral information D12 of the target user 2. Then, the processor 110 generates a questionnaire that is composed of the set questionnaire items.

[0059] For example, assume that the behavioral information D12 shown in Fig. 3 and the question database D20 shown in Fig. 4 are given. Now consider a case where a user with user ID: 1111 is designated as target user 2 for the "Survey on Product A Purchasers." In this case, the processor 110 sets the survey items for the "Survey on Product A Purchasers" based on the history of the behavioral information D12, for example, as follows:

[0060] First, the processor 110 excludes questions No. 1, 3, 4, 6, 7, 8, 9, and 11 from the questions in the "Survey for Product A Purchasers" shown in FIG. 4. This is because these questions can be determined to be known or irrelevant by referring to the behavioral information D12. For example, it can be seen that question No. 4, "Did you participate in the demonstration experiment of Product A?", is known from "Apply to participate in the demonstration experiment of Product A" in the behavioral information D12. By excluding questions in this way, it is possible to reduce the number of questionnaire items to be set. In turn, it is possible to reduce the hassle of answering the questionnaire.

[0061] Secondly, the processor 110 changes the titles of questions No. 2 and 13 of the "Product A Purchaser Survey" shown in FIG. 4 and sets them as survey items. These questions can be given more specific titles by referring to the behavior information D12. For example, the processor 110 changes the title of question No. 2 to "What was your impression of product A at the exhibition?" and sets it as a survey item. For example, the processor 110 changes the title of question No. 13 to "How was the purchase procedure on the EC site?" and sets it as a survey item. By changing the title and setting the survey items in this way, it is possible to reduce the occurrence of a difference in recognition between the survey user 1 and the target user 2 regarding the content of the questions.

[0062] Thirdly, the processor 110 further sets the remaining Nos. 5, 10, and 12 as survey items.

[0063] Fig. 5 shows an example of a questionnaire generated by processor 110 when questionnaire items are set as described above. As shown in Fig. 5, the questions of the generated questionnaire are carefully selected and specified based on the behavior information D12 of target user 2. This is expected to improve the response rate to the questionnaire and the quality of the responses to the questionnaire.

[0064] In addition, for a question item whose answer is known based on the behavior information D12 of the target user 2, the known answer may be presented to the research user 1 as the answer of the target user 2.

[0065] Fig. 6 is a flowchart showing an example of processing executed by the processor 110 in the questionnaire system 10 according to this embodiment. The flowchart shown in Fig. 6 particularly shows an example in which a user who has performed a triggering behavior is the target user 2. The flowchart shown in Fig. 6 is repeatedly executed at every predetermined control period.

[0066] In step S100, the processor 110 acquires the behavior information D12 of each user and stores it in the storage device 120. After step S100, the process proceeds to step S200.

[0067] In step S200, the processor 110 determines whether or not the user has performed a triggering behavior based on the behavior information D12.

[0068] If the user has not performed the triggering behavior (step S200; No), the current process ends without sending the questionnaire.

[0069] If the user has performed the triggering behavior (step S200; Yes), processor 110 designates the user who performed the triggering behavior as target user 2 (step S300). After step S300, the process proceeds to step S400.

[0070] In step S400, the processor 110 acquires the history of the behavior information D12 of the target user 2 specified in step S300. Then, the processor 110 sets questionnaire items based on the history of the behavior information D12 of the target user 2. After step S400, the process proceeds to step S500.

[0071] In step S500, the processor 110 generates a questionnaire made up of the questionnaire items set in step S500. After step S500, the process proceeds to step S600.

[0072] In step S600, the processor 110 transmits the questionnaire generated in step S600 to the target user 2. After step S600, the current process ends.

[0073] In this manner, in the questionnaire system 10 according to the present embodiment, the processor 110 executes the processing. The questionnaire method according to the present embodiment is realized by the processor 110 executing the processing in this manner. Furthermore, the questionnaire program according to the present embodiment is realized by configuring the computer program 121 that causes the processor 110 to execute the processing in this manner.

[0074] 5.Effects As described above, according to this embodiment, the questions constituting the questionnaire are set based on the history of the behavioral information D12 of the target user 2. This makes it possible to carefully select and specify the questions of the questionnaire presented to the target user 2 according to the behavior of the target user 2. This in turn improves the response rate to the questionnaire, and allows the survey user 1 to obtain more meaningful answers from the questionnaire responses.

[0075] 6. Variations The questionnaire system 10 according to the present embodiment may adopt the following modified aspects: In the following description, parts that overlap with the above content are omitted as appropriate.

[0076] 6-1. First modified example The question database D20 may be configured to manage behavioral conditions of the target user 2 that are set as questionnaire items for each question item. Fig. 7 shows an example of question items managed by the question database D20 according to the first modified example. According to the first modified example, in the questionnaire generation process, the processor 110 refers to the behavior information D12 of the target user 2 and sets question items that satisfy the behavioral conditions as questionnaire items.

[0077] For example, assume that the behavioral information D12 shown in Fig. 3 and the question database D20 shown in Fig. 7 are given. Now consider a case where a user with user ID: 1111 is designated as target user 2 for the "Survey on Product A Purchasers." In this case, the processor 110 sets, from the behavioral information D12 shown in Fig. 3, question items No. 2, 4, 6, 8, 9, and 10 of the "Survey on Product A Purchasers" shown in Fig. 7 as survey items.

[0078] By adopting the first modified example, it is possible to obtain the same effect as the above-mentioned configuration. Furthermore, the first modified example can be adopted in combination with the above-mentioned configuration. For example, the question database D20 can be configured to manage the question items shown in FIG. 4 as basic question items, and manage the question items No. 6 and No. 9 and the behavioral conditions shown in FIG. 7 as additional question items. In this case, according to the behavioral information D12 shown in FIG. 3, the questionnaire generated by the processor 110 is the questionnaire shown in FIG. 5 to which the question items No. 6 and No. 9 shown in FIG. 7 have been added. In this way, by adopting the first modified example in combination, it is possible to generate a questionnaire that allows for in-depth digging and hearing of question items. In turn, the survey user 1 can obtain more meaningful answers from the answers to the questionnaire.

[0079] 6-2. Second modified example In the questionnaire generation process, the processor 110 may be configured to determine the order of the questionnaire items based on the order of the behavior of the target user 2 in the history of the behavior information D12. Typically, the processor 110 determines the order of the questionnaire items such that the question items related to the behavior of the target user 2 follow the order of the behavior of the target user 2.

[0080] For example, it is assumed that the behavioral information D12 shown in FIG. 3 and the question database D20 shown in FIG. 4 are given, similarly to the questionnaire shown in FIG. 5. It is also assumed that the processor 110 sets the same questionnaire items as those shown in FIG. 5. According to the second modification, the processor 110 further determines the order of the questionnaire items in the questionnaire to be generated based on the order of the behavior of the target user 2. FIG. 8 shows an example of a questionnaire generated by the processor 110 according to the second modification. The questionnaire shown in FIG. 8 has a different order from Q2 onwards compared to the questionnaire shown in FIG. 5. In particular, the order of the questionnaire items shown in FIG. 8 conforms to the order of the behavior of the target user 2 shown in FIG. 3.

[0081] By adopting the second modified example in this way, the target user 2 can proceed with answering the questionnaire in accordance with the order of his / her own actions. As a result, the stress of the target user 2 in answering the questionnaire can be reduced, and the response rate of the questionnaire can be improved.

[0082] 6-3.Third modified example In the questionnaire generation process, the processor 110 may be configured to determine the order of the questionnaire items based on the ease of answering the questions. The ease of answering the questions can be, for example, an index of the answer speed, the number of characters, the answer rate, etc. for each question item in a past questionnaire. In this case, the processor 110 may be configured to collect these indexes as the questionnaire results. In addition, the ease of answering the questions can also be an index of the behavioral information D12 of the target user 2. For example, the ease of answering the question item "What was your impression at the exhibition booth?" can be determined to be higher the longer the target user 2's stay time at the exhibition booth in the behavioral information D12.
