Description

  The present invention relates to a profiling apparatus, a profiling method, and a program for performing profiling on a user for the purpose of extracting a user's profile.

  There is a questionnaire method in psychology as a way to explain the personal profile (personality and nature) and the state of the inside by verbalization and numericalization. The questionnaire method is similar to a questionnaire, but the content of the question is not a question that appears in marketing or surveys, for example, “YES” or “NO” such as “residence is rented” . For the purpose of extracting a person's characteristics, for example, for questions such as "I will speak to a stranger casually", enter the answer such as "How does it apply" to "How does it apply"? It is what makes you. In the analysis, answer results indicating the degree are handled.

  For example, Patent Document 1 discloses an information providing device that wears a wearable computer and selects and distributes only an advertisement that seems to be effective by acquiring and analyzing a user's stress / fatigue level from a sensor. ing. As a sensor to be used, there is an acceleration sensor, and an action state (walking, running, bicycle, car, train, etc.) can be grasped from data of the acceleration sensor.

  Non-Patent Document 1 presents a human resource management application that presents a questionnaire on a monitor and acquires the facial expression of the user viewing the monitor with a camera to record and analyze facial expression changes together with answers. A research paper on the measurement and comparison of nonverbal attitudes and cognitive behaviors. In this case, the user's situation at the time of answering, such as answering the question while worrying or answering intuitively, can be acquired simultaneously with the answer. By considering the response status at the time of analysis, it seems that the answer is “applicable” but seems to be worried, so it is possible to perform a more accurate analysis that does not seem to match completely.

  Patent Document 2 is a question and answer system using a network system, which shows a change in the form of the respondent, a change in facial expression, a change in voice, a change in pulse rate, a change in sweating amount, a change in body temperature, or a body odor. A question-and-answer system has been disclosed that can detect a person's personality more accurately by detecting and analogizing information such as whether the person is calm or impatient and adding it to the answer result.

  In addition, Patent Document 3 can continuously measure the biological information of the wearer's daily life in a time series and efficiently collect the mental state at that time by conducting an inquiry when the biological information changes greatly. A portable biological information collecting apparatus that can be worn on a human body is disclosed.

  The act of examining the user's profile and inner surface with a questionnaire has the disadvantage that it takes time to execute the question. For example, if you answer 70 questions, if it takes 10 seconds on average to read one question and finish entering the answer, it will take nearly 12 minutes. For example, if it is done at work, the work will be completely interrupted. There is a heavy burden on the user.

  However, since such surveys are mainly focused on the situation at that time, there are elements that vary in the morning and evening, and elements that change from day to day. It will be necessary to carry it out in the form of every day. In such a situation, a device for reducing the burden on the user is necessary for repeated implementation.

  On the other hand, in addition to environmental stimuli that are placed, such as temperature, humidity, and brightness, which are relatively small changes in the office, the user receives large changes from the voices of people around the phone and the eyes of people walking. Stress and tension change with stimulation. Especially in places where it is difficult to protect privacy, such as in offices, it is easy to be affected by stimuli while inputting answers to questionnaires about your personality and inside, and the state changes at the time of responses are severe. There is a possibility.

  As a method of reducing the unevenness of answers when the state of the inner surface changes in this way, there is a method of increasing the number of questions and averaging by repeating the same question over and over again. However, for example, there is no distinction between results that are confidently answered and those that are not confidently answered, so even if you look at the results alone, you will not know the difference in the judgment process. I have to do it many times. According to this method, the number of answers increases more than necessary, which imposes a burden on the user.

  In other words, in order to examine a user's profile and inner surface using a questionnaire in a place where there are many stimuli such as in offices and where the answer is likely to be uneven, consider changes in the internal situation such as stress and tension It is necessary to reduce the burden on the user.

  In addition, although patent document 2 has the description that the property is estimated from the change of a respondent's state, the specific analogy method is not described. Patent Document 2 is intended to make it possible to accurately grasp and evaluate the character of a person, and does not re-question based on biological information for the purpose of reducing the burden on the user. Absent. Patent Document 3 collects answer information by conducting an inquiry when biometric information changes greatly, and reduces the burden on the user in profiling in which a question for examining the characteristics of the user is presented to the user to obtain an answer. For this purpose, the question is not re-questioned based on the biological information.

  The present invention has been made in view of such problems, and can reduce the burden of performing profiling many times on a user during profiling in which a question for examining a user's characteristics is presented to the user to obtain an answer.

  In the present invention, biometric information refers to, for example, myoelectric potential, heart rate (HR), respiration rate, blood pressure, volume pulse wave, pupil diameter, body surface skin temperature, and utterance unit capable of measuring tension and stress. These include the number of words per hour, the number of nods per unit time, the number of body shaking vibrations, the number of blinks per unit time, myoelectric potential, and brain waves. For example, the number of blinks increases according to interest and stress on the subject. The number of heartbeats and spoken words varies depending on the degree of tension. The opening of the pupil varies depending on the degree of arousal. The number of nods and shaking varies depending on the degree of calmness. The biological information uses information representing the state of the body such as the degree of tension, stress, arousal level, calmness, etc. that change in these situations.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail with reference to drawings. In addition, the same code | symbol is attached | subjected to the part which is the same or it corresponds in a figure.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of a profiling system according to Embodiment 1 of the present invention. The profiling system 101 includes a profiling device 1 and a user terminal 6. The profiling device 1 and the user terminal 6 can communicate with each other via a network (not shown). Although one user terminal 6 is shown as a representative, a plurality of user terminals 6 may be connected to the network. Further, the user terminal 6 may be a part of the profiling device 1 or an attached device.

  The profiling device 1 includes an information acquisition unit 11, an information storage unit 12, an answer determination unit 13, an output screen generation unit 14, and a question information storage unit 15. The information storage unit 12 and the question information storage unit 15 may be different devices connected to the profiling device 1 via a network. The user terminal 6 includes an input unit 61, a display unit 62, and a biological information acquisition unit 63.

  The information acquisition unit 11 of the profiling device 1 receives response information indicating an answer input by the user from the user terminal 6. Further, the information acquisition unit 11 receives user biometric information transmitted from the user terminal 6. Note that the user terminal 6 may transmit the biometric information when the user answers to the information acquisition unit 11 in association with the response information, or the information acquisition unit 11 acquires the response information at the same time. The biological information may be associated with the answer information.

  The information storage unit 12 stores the response information received by the information acquisition unit 11, the response time information indicating the acquired time, and the question information in association with each other. Further, the information storage unit 12 assigns the current time to the user's biometric information sequentially received from the user terminal 6 by the information acquisition unit 11 and stores it in time series. The information storage unit 12 stores these pieces of information for each user. When the user terminal 6 or the information acquisition unit 11 associates biometric information with answer information, the information storage unit 12 stores the acquired answer information, biometric information corresponding to the answer information, and question information in association with each other.

  The answer determination unit 13 determines whether or not to re-question based on the biological information corresponding to the answer information.

  The output screen generation unit 14 calls the question information from the question information storage unit 15 described later, and generates an output screen for displaying the question information. If the answer determination unit 13 determines that the re-question is to be performed, the output screen generation unit 14 calls re-question information that is different question information classified into the same survey characteristics as the question information, and the re-question Generate an output screen that displays the information.

  The question information storage unit 15 classifies and stores the question information indicating the question for checking the user characteristics according to the survey characteristics indicating the user characteristics checked by the question information.

  The input unit 61 of the user terminal 6 receives an answer from the user. The display unit 62 displays the output screen sent from the output screen generation unit 14 of the profiling apparatus 1. The biometric information acquisition unit 63 acquires the biometric information of the user from a myoelectric sensor or a heart rate monitor (not shown) worn by the user. The user terminal 6 may be a PC via a network such as the Internet or a mobile phone. Moreover, the input of the answer may be performed on a Web page or an e-mail may be used.

  FIG. 2 is a diagram for explaining an example of an output screen according to the first embodiment. In the example of FIG. 2, the output screen 621 displayed on the display unit 62 of the user terminal 6 displays the question information 623 “I don't sleep well recently”, and the user can input 1 to the answer. 5 key buttons 622 are displayed. The key button group 622 has a symbol 1 “not so”, a symbol 2 “not so”, a symbol 3 “neither”, a symbol 4 “somewhat”, and a symbol 5 “yes” "Is". That is, as the number of key buttons input by the user is larger, it means that the user is more applicable to the items indicated in the question information 623. The information acquisition unit 11 acquires response information indicating which key button the user has pressed from the user terminal 6, and the information storage unit 12 receives the question information 623 and the response time information indicating the time when the response information is acquired. It is stored in association with the answer information.

  Note that the user terminal 6 may transmit the time when the user answers as response time information to the information acquisition unit 11 in association with the response information. At this time, since the user completes the answer input by simply pressing any one of the key buttons 622, the user terminal 6 sets the time at the moment of pressing as the answer time information. However, when it takes time for the user to answer, as in the case where the answer is a descriptive formula, the user terminal 6 associates the answer start time and the answer end time with the answer information as the answer time information, and the information acquisition unit 11 to be transmitted.

  FIG. 3 is an example of a graph in which the value of the user's biometric information is plotted on the vertical axis and the time is plotted on the horizontal axis. In the example of FIG. 3, the myoelectric potential is measured as biological information to measure the degree of tension, and the higher the myoelectric potential, the higher the degree of tension. The output screen generation unit 14 generates an output screen 621 that displays question information as illustrated in FIG. 2 and transmits the output screen 621 to the user terminal 6. The time when the output screen 621 for displaying the first question is transmitted to the user terminal 6 is the presentation time t1. The user terminal 6 displays the received output screen 621 on the display unit 62. The user presses one of the key buttons 622 as an answer to the question displayed on the presented output screen 621. The information acquisition unit 11 acquires response information indicating the user's response from the user terminal 6. The time when the answer information is acquired is the answer time t2, and the information storage unit 12 stores the answer time t2 as the answer time information in association with the answer information and the question. Similarly, the time when the output screen 621 displaying the second question is transmitted to the user terminal 6 is the presentation time t3, and the time when the information acquisition unit 11 acquires the answer information for the question is the answer time t4, the third question The time when the output screen 621 for displaying the message is transmitted to the user terminal 6 is the presentation time t5, and the time when the information acquisition unit 11 acquires the answer information for the question is the answer time t6.

  Since the information storage unit 12 stores the user's biometric information in time series, the information storage unit 12 can search for the degree of tension at the time of answering at the answering time. In the example of FIG. 3, the tension at the answer time t2 is y1, the tension at the answer time t4 is y2, and the tension at the answer time t6 is y3. For example, for the tension of the question, the average of the biological information from the presentation time t1 to the answer time t2 may be used as the tension, or the average of the biological information from the answer time t2 to the presentation time t3 is set as the tension. It is good. As described above, when the user takes time to answer, the answer start time and answer end time are set as answer time information. In this case, the degree of tension may be the average of the values of the biological information from the answer start time to the answer end time, or a function that can approximate the value of the biometric information from the answer start time to the answer end time may be used. Good.

  FIG. 4 is a diagram illustrating the data structure of information stored in the information storage unit in the first embodiment. The information storage unit 12 stores a data table as shown in FIG. 4A as information in which question information, answer time information, and answer information are associated with each other. In the order that the output screen generation unit 14 calls from the question information storage unit 15, the question information, the survey characteristics, the response information, and the response time information are stored in association with each other. FIG. 4B is a data table of biometric information corresponding to the response time information included in the data table of FIG. The biometric information corresponding to the answer time information may be made into a data table as shown in FIG. 4B, or may be searched as needed. A data table as shown in FIG. 4 is created every time profiling is performed. That is, the reply information stored in the same data table is a result of profiling performed in the same time zone.

  In FIG. 4, the first question Q1 is “A1”, and the survey characteristic that is the user's characteristic investigated by the question information A1 is “XXX”. The user's answer to the question information A1 is “4”, and the time when the answer information “4” is acquired is “t2”. Furthermore, the degree of tension retrieved at the answer time “t2” is “y1”. The time and tension in FIG. 4B correspond to the answer time and tension in FIG. In the example of FIG. 4, the characteristics of the user investigated by the question information are associated with the answer information as the investigation characteristics, but the investigation characteristics may not be associated with the answer information.

  The answer determination unit 13 refers to the data table shown in FIG. When the information acquisition unit 11 acquires the answer information “4” for the question information A1, the answer determination unit 13 refers to the past answer information associated with the question information A1 stored in the information storage unit 12, and Biometric information is searched from past answer time information associated with the information A1. For example, when the average of the values of the biometric information searched for in the past answer time information whose past answer information is “4” is “y1”, the answer determination unit 13 determines “do not re-question”. . On the other hand, if the average of the values of the biometric information retrieved with the past answer time information whose past answer information is “4” is not “y1”, the answer determination unit 13 determines “re-question”. .

  Also, if the average of past answer information whose biometric information retrieved from past answer time information is “y1” is “4”, the answer determination unit 13 determines that “no re-question”. . If the average of the past answer information whose biometric information retrieved from the past answer time information is “y1” is not “4”, the answer determination unit 13 determines “re-question”. If the average of past response information is a value that approximates “4”, it is treated as “4”, and the average of the values of biometric information retrieved from past response time information is a value that approximates “y1”. For example, the width may be given so as to be handled as “y1”. Alternatively, for example, if the biometric information indicates a degree of tension, the value is classified into three stages of biometric information classifications of “high tension”, “medium tension”, and “low tension”, and the answer determination unit 13 selects past answer information. If the average of the values of the biometric information retrieved with the past answer time information with the same is not the same biometric information classification, or the biometric information with the same biometric information retrieved with the past answer time information When the averages of past answer information as classifications are not the same or approximate values, it may be determined that “re-question”. The biometric information classification will be described in detail in Embodiment 3.

  In the example of FIG. 4, it is assumed that the output screen generation unit 14 calls the question information one by one in the order of XX, △△, xx, and □□. The question Q1 is determined to be re-questioned, and the second question Q2 is re-questioned by the user with question information A2 having the same investigation characteristics as the question information A1. The question Q2 is determined not to be re-questioned, and the third question Q3 is questioned to the user by question information B1 for examining the next investigation characteristic ΔΔ. The question Q3 is determined to be re-questioned, and the fourth question Q4 is re-questioned by the user with question information B2 having the same investigation characteristics as the question information B1. Hereinafter, the question Q4 is determined not to be re-questioned, the fifth question Q5 and the sixth question Q6 are determined to be re-questioned, and the seventh question Q7 is determined not to be re-questioned.

  The answer determination unit 13 may determine that the question is re-questioned when the biometric information corresponding to the answer information exceeds a preset threshold value, or the biometric information corresponding to the immediately previous answer information may be set to a preset threshold value. If it exceeds, the tension state of the person changes but is hard to change suddenly. Therefore, it may be determined that the next question also exceeds the threshold value and the question is re-questioned.

  FIG. 5 is a diagram illustrating a data structure of information stored in the information storage unit when the user terminal or the information acquisition unit associates biometric information with answer information. When the information acquisition unit 11 receives biometric information at the same time as the answer information and stores the response information and biometric information acquired by the information storage unit 12 in association with the question information, the information storage unit 12 associates with the question information. A data table as shown in FIG. 5 is stored as answer information and biometric information corresponding to the answer information. In the order that the output screen generation unit 14 calls from the question information storage unit 15, the question information, the survey characteristics, the response information, and the biological information corresponding to the response information are stored in association with each other. In this case, there is no need to search the biometric information at the answer time.

  FIG. 6 is a flowchart showing an example of the profiling operation according to the first embodiment. First, the output screen generation unit 14 calls the question information from the question information storage unit 15 (step S11), and generates an output screen that displays the question information (step S12). The output screen generation unit 14 transmits the generated output screen to the user terminal 6 (step S13). The user terminal 6 displays the received output screen on the display unit 62 and presents question information to the user. The user inputs an answer to the question information to the input unit 61, and the user terminal 6 transmits answer information indicating the answer to the information acquisition unit 11.

  The information acquisition unit 11 acquires the response information from the user terminal 6 (step S14), and the information storage unit 12 stores the response time information indicating the time when the response information is acquired, the question information, and the response information in association with each other. (Step S15).

  Next, the answer determination unit 13 searches for and calls the biometric information at the time indicated by the answer time information (step S16). The answer determination unit 13 further calls the biometric information retrieved by the past answer information stored in the information storage unit 12 in association with the question information and the answer time information corresponding to the answer information (step S17). Next, the answer determination unit 13 determines that the average of the values of the biometric information retrieved with the past answer time information with the same past answer information is not the same as the value of the biometric information, or the past answer When the average of the past answer information in which the value of the biometric information searched for by the time information is the same as the value of the biometric information is not the same, it is determined to “re-question” (step S18; YES).

  When the answer determination unit 13 determines to “re-question”, the output screen generation unit 14 calls re-question information, which is different question information classified into the same survey characteristics as the question information, from the question information storage unit 15 ( Step S19), an output screen for displaying the re-question information is generated (Step S12). If the answer determination unit 13 determines “re-question” in step S18, the process repeats step S19 and steps S12 to S18.

  On the other hand, the answer determination unit 13 determines whether the average of the values of the biometric information retrieved from the past answer time information with the same past answer information is the same as the value of the biometric information, or the past answer time information. When the average of the past answer information in which the value of the biometric information retrieved in step 1 is the same as the value of the biometric information is determined to be “no re-question” (step S18; NO). If the answer determination unit 13 determines that “do not re-question”, if there is next question information (step 20; YES), the process repeats steps S12 to S20. If there is no next question information (step 20; NO), the process ends.

  When the user terminal 6 or the information acquisition unit 11 associates the biological information with the answer information, the information storage unit 12 stores the answer information, the question information, and the biological information corresponding to the answer information in association with each other in step S15. To do. In this case, step S16 is not necessary. In the flowchart shown in FIG. 9 described later, when the user terminal 6 or the information acquisition unit 11 associates the biological information with the answer information, the same processing is performed.

  As described above, according to the profiling system 101 of the first embodiment, during profiling, it is compared with past biometric information and answer information, and only questions that have different biometric information or answer information are re-questioned. Eliminate waste and reduce the burden of profiling multiple times on the user. As a result, the answer information necessary for profiling can be efficiently collected, and the efficiency of profiling can be expected.

(Embodiment 2)
The configuration of the profiling system according to the second embodiment of the present invention is the same as that of the profiling system 101 according to the first embodiment. In the second embodiment, the answer determination unit 13 determines whether or not to confirm the answer to the user based on the biological information at the time indicated by the answer time information associated with the answer information. The output screen generation unit 14 calls confirmation information asking whether or not to change the answer from the question information storage unit 15 and generates an output screen that displays the confirmation information. The question information storage unit 15 stores confirmation information for asking the user whether or not to change the answer. The confirmation information is not limited to the question information storage unit 15 and may be stored in another storage unit or storage device.

  FIG. 7 is a diagram illustrating an example of an output screen according to the second embodiment. In the example of FIG. 7, the output screen 621 displayed on the display unit 62 of the user terminal 6 displays the question information 624 “No appetite recently”, and the user presses a key button for the question information 624. A state in which the answer information “4” is input by pressing 625 is displayed. The key button 625 is displayed so that it can be distinguished from other key buttons when pressed by, for example, clicking with a mouse. In response to this answer information, the output screen generation unit 14 displays confirmation information 626 as a popup for asking the user whether or not to change the answer. The confirmation information 626 includes a question sentence “Is this OK?”, A “Yes” selection button 627, and a “Change” selection button 628. The user presses the selection button 627 if the input answer information “4” is correct, and presses the “change” selection button 628 to change it.

  When the user presses the “change” selection button 628, the output screen 621 transitions to a state before the user inputs the answer information, and the user can input the answer information again. At this time, the information storage unit 12 overwrites and stores the answer information newly input by the user as answer information for the question information 624.

  FIG. 8 is a diagram for explaining the data structure of information stored in the information storage unit in the second embodiment. In the second embodiment, the information storage unit 12 stores a data table as shown in FIG. 8A as answer information in which question information and answer time information are associated with each other. In the order that the output screen generation unit 14 calls from the question information storage unit 15, the question information, the survey characteristics, the response information, and the response time information are stored in association with each other. FIG. 8B is data obtained by converting the biological information corresponding to the response time information included in the data table of FIG. The biometric information corresponding to the answer time information may be converted into data as shown in FIG. 8B, or may be searched as needed.

  The answer determination unit 13 determines whether or not to check with reference to the data table shown in FIG. When the information acquisition unit 11 acquires the answer information “3” for the question information B1, the answer determination unit 13 acquires the tension y2 searched at the answer time t4 indicated by the answer time information and the answer time indicated by the immediately previous answer time information. Call the tension y1 retrieved at t2. The answer determination unit 13 obtains a difference between y1 and y2, and determines that “confirm” if the difference is larger than a preset threshold value. It is determined that “do not check”. Each time the answer determination unit 13 acquires answer information, the answer determination unit 13 compares the degree of tension corresponding to the answer time information with the degree of tension corresponding to the immediately previous answer time information to obtain a difference.

  In the example of FIG. 8, it is assumed that the output screen generation unit 14 repeatedly calls the question information one by one in the order of XX, △△, xx, and □□. When the answer determination unit 13 acquires the answer information 4 of the fourth question Q4, the answer determination unit 13 searches for the tension y4 searched at the answer time t8 indicated by the answer time information and the answer time t6 indicated by the immediately previous answer time information. Call the tension y3 and find the difference between y3 and y4. Here, the difference between y3 and y4 is larger than a preset threshold value, and the answer determination unit 13 determines “confirm”. When the answer determination unit 13 determines “confirm”, the output screen generation unit 14 calls the confirmation information from the question information storage unit 15 and generates an output screen that displays the confirmation information. The user terminal 6 displays this on the display unit 62, and the user can input the answer again. In the example of FIG. 8, the user changes the answer information of the question Q4 and inputs the answer information “3” again. As a result, the information storage unit 12 overwrites and stores the response information from “4” to “3”. Here, for the sake of convenience, overwrite save is indicated by an arrow, but only answer information “3” is actually stored as answer information of question Q4.

FIG. 9 is a flowchart showing an example of the profiling operation according to the second embodiment. First, the output screen generation unit 14 calls the question information from the question information storage unit 15 (step S21), and generates an output screen that displays the question information (step S22). The output screen generation unit 14 transmits the generated output screen to the user terminal 6 (step S23). The user terminal 6 displays the received output screen on the display unit 62 and presents question information to the user. The user inputs an answer to the question information to the input unit 61, and the user terminal 6 transmits answer information indicating the answer to the information acquisition unit 11.
The information acquisition unit 11 acquires the response information from the user terminal 6 (step S24), and the information storage unit 12 stores the response time information indicating the time when the response information is acquired, the question information, and the response information in association with each other. (Step S25).

  Next, the answer determination unit 13 searches for and calls the biometric information at the time indicated by the answer time information (step S26). The answer determination unit 13 further calls the biometric information searched with the answer time information immediately before the answer time information (step S27). Next, the answer determination unit 13 calculates the difference between the value of the biometric information at the time indicated by the answer time information and the value of the biometric information retrieved from the immediately previous answer time information, and this difference is a preset threshold value. If it is larger than that, it is determined to “confirm” (step S28; YES).

  If the answer determination unit 13 determines “confirm”, the output screen generation unit 14 calls confirmation information asking whether or not to change the answer from the question information storage unit 15 (step S29). An output screen to be displayed is generated (step S30). The output screen generation unit 14 transmits the generated output screen to the user terminal 6 (step S31). The user terminal 6 displays the received output screen on the display unit 62 and presents confirmation information to the user. The user inputs an answer to the confirmation information to the input unit 61, and the user terminal 6 gives the information acquisition unit 11 information indicating that the answer is changed when the answer is changed, and information indicating that the answer is not changed when the answer is not changed. Send.

  When the user changes the response and the information acquisition unit 11 acquires the response information (step S32; YES), the information storage unit 12 overwrites and stores the response information and the original response information (step S33). When the user does not change the answer and the information acquisition unit 11 acquires information indicating that the answer is not changed (step S32; NO), it is determined whether there is next question information (step 34).

  On the other hand, if the difference between the value of the biometric information at the time indicated by the answer time information and the value of the biometric information searched for by the immediately previous answer time information is smaller than a preset threshold, “No confirmation” is determined (step S28; NO). If the answer determination unit 13 determines that “do not confirm”, if there is next question information (step 34; YES), the process repeats steps S21 to S34. If there is no next question information (step 34; NO), the process ends.

  As described above, according to the profiling system of the second embodiment, during the profiling, by confirming whether or not to change the answer for which there has been a sudden change in biometric information, the user calms down and answers again. It is possible to reduce unevenness in answering by the user himself / herself. This can reduce the burden of performing profiling again for the user for averaging. In addition, it is possible to efficiently collect answer information necessary for profiling, and it can be expected that profiling will be more efficient.

  FIG. 11 is an example of a graph in which the value of the user's biological information is plotted on the vertical axis and the time is plotted on the horizontal axis. In the example of FIG. 11, the myoelectric potential is measured as biometric information in the same manner as in FIG. 3, and the degree of tension is measured. The higher the myoelectric potential, the higher the degree of tension. The biometric information classifying unit 17 sets threshold values α and β in advance for the degree of tension, sorts biometric information having a value larger than α into “high tension” biometric information classification, and biometric information having a value smaller than α and a larger value than β. Are classified into the “medium tension” biometric information classification, and the biometric information having a value smaller than α is classified into the “low tension” biometric information classification. Here, since the tension y1 searched at the answer time t2 is larger than α, it is classified into the “high tension” biological information classification, and the tension y2 searched at the answer time t4 is smaller than α and larger than β. The biological information classification of “tension” is sorted, and the tension y3 searched at t6 is smaller than β, so the biological information classification of “low tension” is sorted.

  FIG. 12 is a diagram for explaining the data structure of answer information for each biometric information category according to the third embodiment. The biometric information classifying unit 17 sorts the answer information stored in the information storage unit 12 into each biometric information class based on the value of the corresponding biometric information. FIG. 12A is a data table that stores the averaged response information of each survey characteristic for each time when profiling is performed on the response information belonging to “high tension”. FIG. 12B is a data table that stores, for the answer information belonging to “medium tension”, values obtained by averaging the answer information of each survey characteristic for each profiling time. FIG. 12C is a data table in which the response information belonging to “low tension” is stored with a value obtained by averaging the response information of each survey characteristic for each profiling time. Here, it is assumed that profiling was performed at morning time T1, daytime time T2, and night time T3 on the same day.
