The message output method of the present invention is a message output method in a tutorial system having an input means and an output means, and a progress confirmation means for confirming the progress of the user from a tutor, and a time confirmation means for confirming an elapsed time from a timer. A membership function specifying means for specifying a membership function from a section of the membership function group stored in the membership function storing means based on an instruction from the user via the input means, and the membership function specifying means Fuzzy inference means for performing fuzzy inference on message output based on the progress of the user passed from the membership function and message selection means specified by, and message storage that stores some messages to be output to the user By means and the time confirmation means Each time the permitted elapsed time reaches a certain time, the user's progress is passed to the fuzzy inference means to perform fuzzy inference on the message output, and the fuzzy inference means stores the fuzzy inference result in the message saving means based on the inference result. Message selection means for selecting a message to be output to the user via the output means from the group of stored messages.

[Action]

In the message output system of the present invention, the progress confirmation means confirms the progress of the user from the tutor, the time confirmation means confirms the elapsed time from the timer, and the membership function designation means gives an instruction from the user via the input means. A user who specifies a membership function from the membership function group stored in the membership function storage means based on the above, and the fuzzy inference means is passed from the membership function specified by the membership function specification means and the message selection means. Fuzzy inference based on the progress of the message output, the message storage means stores some messages to be output to the user, and the message selection means reaches a certain time that is confirmed by the time confirmation means. Each time, the progress of the user is passed to the fuzzy inference means and a message is displayed. Selecting a message to be output to the user via the output means from among the group messages stored in message storage means based on the inference result of the fuzzy inference by the fuzzy inference means to perform the fuzzy inference for the output.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the message output system of the present invention. In FIG. 1, 1 is an input means, 2 is an output means, 3 is a tutor, 4 is a progress check means, 5 is a timer,
6 is a time confirmation means, 7 is a message selection means, 8 is a membership function designation means, 9 is a membership function storage means, 10 is a fuzzy inference means, and 11 is a message storage means. is there.

FIG. 2 is a flow chart showing a specific example of the processing of the message selecting means 7. The processing of the message selection means 7 is performed by inputting an elapsed time value step 21, determining whether a predetermined time has elapsed after outputting the previous message step 22, and inputting a progress value value step 23.
, A fuzzy inference step 24, a message retrieval step 25, and a message output step 26.

FIG. 3 is a flow chart showing a specific example of the processing of the membership function designating means 8. The processing of the membership function specifying means 8 includes a user desired input step 31, a user desired matching membership function specification step 32, and a specified membership function output step 33.

FIG. 4 is a diagram showing a concrete example of a message stored by the message storage means 11 and a graph of a fuzzy function corresponding thereto.

Next, the operation of the message output method of the present embodiment configured as described above will be described.

When the user is using the tutor 3 via the input means 1, the progress confirmation means 4 confirms the progress of the user from the tutor 3 (inputs a value indicating the progress), and the time confirmation means 6 uses a timer. Confirm the elapsed time (use time of the tutorial system by the user) from 5 (enter a value indicating the elapsed time).

When the message selecting means 7 determines that a certain time has elapsed from the previous message output based on the elapsed time confirmed by the time confirming means 6, the fuzzy state of the user confirmed by the progress confirming means 4 is fuzzy. The fuzzy inference regarding the message output is performed by passing it to the inference means 10.

Prior to this, the membership function designating means 8 designates the membership function in accordance with the user's desire (preference regarding the strictness of the educational method) inputted through the input means 1, and the membership function storing means in advance. The membership function is retrieved from the membership function group stored in 9 and passed to the fuzzy inference means 10. The membership function storage unit 9 stores the membership function input (can be added later) from the user or the like via the input unit 1 and the membership function designating unit 8.

When the fuzzy inference means 10 receives a fuzzy inference instruction from the message selection means 7, it converts a membership function to a fuzzy function that the user desires, and uses the fuzzy function to perform fuzzy inference on message output. .

Based on the inference result of the fuzzy inference by the fuzzy inference means 10, the message selection means 7 selects a message to be output from the message group stored in the message storage means 11 and outputs it to the user via the output means 2. Output.

Next, a specific operation will be described with reference to FIGS.

The message selection means 7 inputs the value of the elapsed time indicated by the timer 5 confirmed by the time confirmation means 6 (step
21), a certain time since the last message output (here,
It is determined whether 15 minutes have elapsed (step 22).

If 15 minutes have not passed in this judgment, check the time again 6
(Step 21), and if 15 minutes have elapsed, the value of the user's progress indicated by the tutor 3 confirmed by the progress confirmation means is input (step 23).

On the other hand, the membership function specifying means 8 is the input means 1
The user's wish (a value indicating the wish) is input via (step 31), and the user's wish is selected from among the membership function groups stored in the membership function storing means 9 based on the input value. The matching membership function is designated (specified) (step 32), and the designated membership function is passed to the fuzzy inference means 10 (step 33).

The fuzzy inference means 10 uses the membership function passed in step 33 according to the instruction from the message selection means 7 to perform fuzzy inference based on the user's progress value input in step 23 and execute the inference result. Is output (step 24).

The message selecting means 7 extracts the message to be output from the message storing means 11 based on the inference result (step 25), and outputs the extracted message via the output means 2 (step 26).

Further, a specific example of the message shown in FIG. 4 will be described.

The value of the elapsed time confirmed by the time confirmation means 6 has reached 15 minutes, the value of the user's advancement confirmed by the advancement confirmation means 4 is "50", and the membership function is designated by the user's instruction. The graph of the fuzzy function based on the specification of means 8 is shown in Fig. 4 (message "Very enthusiastic, please do your best", message "Fight! Fight! Fair" and message "Are you tired? Graph of fuzzy function corresponding to each message of "sho"
Fuzzy inference means 10 according to an instruction from the message selection means 7
Performs fuzzy inference based on the values of the message goodness of fit of “1.5”, the message goodness of fit of “4.8”, and the message goodness of fit of “1.0”, and identifies the message as the message with the highest goodness of fit. Output the result.

The message selection means 7 determines, based on the inference result,
The message “Fight! Fight! Fair” is selected in the message storage means 11 and is output to the user via the output means 2.

〔The invention's effect〕

As described above, according to the present invention, the message output when the tutorial system is used is performed according to the inference result of the fuzzy inference based on the progress of the user at regular time intervals, so that the user can be finely managed with respect to the tutorial system. It is possible to output an appropriate message at regular time intervals that incorporates an educational method and a sense of ambiguity that suits the user's wishes, and even if the user's progress is slow, the message from the tutor to the user will be sufficient. The effect is that it can be output.
