  If the received data is a questionnaire response (YES in step S104), CPU 110 stores the answer in answer table 124 (step S106). CPU 110 updates tabulation table 125 based on the new answer (step S108). CPU110 performs the process from step S118.

  If the received data is not a questionnaire response (NO in step S104), CPU 110 determines whether or not the number of consecutive message exchanges N is greater than a predetermined number, for example, three (step S112). When the number of consecutive message exchanges N is equal to or less than the predetermined number (NO in step S112), CPU 110 creates a normal message (step S118) and increments the number of consecutive times N (step S120). . CPU110 performs the process from step S136.

  When the number N of consecutive message exchanges is greater than the predetermined number (YES in step S112), CPU 110 reads out other predetermined conditions (step S114). CPU 110 determines whether or not other predetermined conditions are satisfied (step S116).

  In the present embodiment, as another predetermined condition, CPU 110 determines whether or not the user has shown interest in the topic or theme of the most recent message or the most recent message (step S116). For example, when the message from the user includes a positive keyword such as “I love!” Or “Like” or a question from the user, the user shows an interest in the topic or theme. (If YES in step S116), the process from step S132 is executed.

  On the other hand, when a positive keyword is not included in the message from the user, CPU 110 determines that the user has not shown interest in the series of messages (NO in step S116), and the processing from step S118. Execute.

  The CPU 110 asks the user “Yes” or “Yes” after asking the user “Is interested?” Or “Can you cooperate with a simple questionnaire?” Via the electrical device 300. When there is an answer such as, it is determined that the user has expressed interest in the topic or theme, that is, the predetermined condition is satisfied (in the case of YES in step S116), and “No” for the question. If there is an answer “Yes” or no answer, it may be determined that the user did not show interest in the topic or theme, that is, the predetermined condition was not satisfied (in step S116). If NO).

In step S132, the CPU 110 reads the next problem from the problem table 123 and resets the number of consecutive times N (step S134). CPU110 converts the question and message of a questionnaire into audio | voice data (step S136). CPU110 transmits audio | voice data to the electric equipment 300 via the communication interface 160 (step S138).
<Third Embodiment>

  Furthermore, it is preferable that the questionnaire provider can set a situation that the user wants to answer for each problem. For example, it is preferable that a problem to be answered in a cold morning, a problem to be answered on a rainy day, a problem to be answered by a user living near the sea, or the like can be specified.

  In the present embodiment, the memory 120 of the server 100 may store an output condition table 126 as shown in FIG. The output condition table 126 includes a condition ID, a questionnaire ID, a problem number, a day of the week, a time zone, weather, and the like for each output condition, that is, for each problem or questionnaire for which a condition suitable for output is set. Including the corresponding relationship. For example, the CPU 110 of the server 100 receives questionnaire questions and setting conditions from the input terminal 200 via the communication interface 160 and accumulates them in the output condition table 126.

  In the present embodiment, in step S110 of FIG. 8, step S116 of FIG. 12, etc., CPU 110 determines whether or not the current day of the week, time, weather, temperature, etc. match the output conditions of the next question in the questionnaire. to decide. Then, the CPU 110 executes the process from step S132 when the current day of the week, time, weather, temperature, and the like match the output condition of the next question in the questionnaire, and executes the process from step S118 when they do not match. .

  Alternatively, the memory 120 of the server 100 may store a second output condition table 126B as shown in FIG. The output condition table 126B includes a correspondence relationship between a condition ID, a questionnaire ID, a problem number, a user address, a user postal code, a user age, a user gender, and the like for each output condition. Also in this case, for example, the CPU 110 of the server 100 receives questionnaire questions and setting conditions from the input terminal 200 via the communication interface 160 and accumulates them in the output condition table 126B.

Then, in step S110 of FIG. 8, step S116 of FIG. 12, etc., the CPU 110 matches the output condition of the next question in the questionnaire such as the user's address, the user's postal code, the user's age, and the user's gender. Judge whether to do. And CPU110 performs the process from step S132, when a user's address, a user's postal code, a user's age, a user's sex, etc. match the output conditions of the next problem of a questionnaire, and does not match In this case, the processing from step S118 is executed.
