The configuration in the determination stage for determining is separately shown.

[Preparation stage]
First, the configuration of the subjective evaluation value determination apparatus 1 in the preparation stage will be described with reference to FIG. In FIG. 1, the subjective evaluation value determination device 1 includes a user behavior data acquisition unit 11, a user behavior data storage unit 12, a classification unit 13, a subjective evaluation value assignment unit 14, and a behavior pattern data storage unit 15 with subjective evaluation values. Prepare.

  The user behavior data acquisition unit 11 acquires user behavior data indicating the behavior of the user when specific type information is presented to the user. The specific type information is information belonging to a specific information type. Specific information types include, for example, problems (for example, problems with English words, expertise, etc.), news, information generation notification (for example, information generation notification in social network service (SNS)), and the like. .

  In the preparation stage, the user behavior data acquisition unit 11 acquires user behavior data indicating the behavior of the user when the specific type information with the objective evaluation value is presented to the user. The specific type information with an objective evaluation value is specific type information to which a predefined objective evaluation value is assigned. For example, for the problem of English words, the difficulty level of the problem is an objective evaluation value, and the problem of English words to which a predetermined difficulty level is assigned becomes specific type information with an objective evaluation value. As the objective evaluation value, in addition to the difficulty level, for example, a frequency, a utilization rate, a validity rate, and the like can be given.

  The user behavior data acquisition unit 11 receives a specific type information presentation timing signal with an objective evaluation value. The specific type information presentation timing signal with objective evaluation value indicates the timing at which the specific type information with objective evaluation value is presented to the user. The user behavior data acquisition unit 11 acquires user behavior data indicating the behavior of the user who is presented with the specific type information with the objective evaluation value, triggered by the input of the specific type information presentation timing signal with the objective evaluation value. To do.

  Examples of user behavior include head movement and utterance. The user behavior data acquisition unit 11 has detection means for acquiring user behavior data. Examples of the detecting means include an acceleration sensor, a direction sensor, and a volume sensor.

  The user behavior data storage unit 12 stores the user behavior data acquired by the user behavior data acquisition unit 11 and the objective evaluation value in association with each other when the specific type information with the objective evaluation value is presented. The user behavior data storage unit 12 objectively evaluates the specific type information with the objective evaluation value presented to the user at the timing indicated by the specific type information presentation timing signal with the objective evaluation value to the user behavior data acquisition unit 11. A value is entered. The user behavior data storage unit 12 stores the input objective evaluation value and the user behavior data acquired by the user behavior data acquisition unit 11 in association with each other.

  The classification unit 13 classifies the user behavior indicated by the user behavior data stored in the user behavior data storage unit 12 into a plurality of behavior patterns. For this classification, cluster analysis is used. By the cluster analysis, a plurality (N) of user behavior data is classified into a plurality (K) of clusters Ci (i = 1,..., K). One cluster Ci corresponds to one action pattern.

  The subjective evaluation value assigning unit 14 sets the objective evaluation value associated with the corresponding user behavior data stored in the user behavior data storage unit 12 for each of the plurality of behavior patterns classified by the classification unit 13. Based on the subjective evaluation value. Specifically, a subjective evaluation value corresponding to an average value of objective evaluation values of user behavior data belonging to the same cluster Ci is assigned to the cluster Ci. At this time, the average value of the objective evaluation values of each cluster Ci may be normalized, and a subjective evaluation value corresponding to the normalized value may be assigned to the cluster Ci.

  For example, for the problem of English words, the degree of understanding is used as the subjective evaluation value corresponding to the difficulty level (objective evaluation value). First, for each cluster Ci regarding the English word problem, an average value of the difficulty levels of the user behavior data belonging to the same cluster Ci is calculated. Next, the clusters Ci are arranged in descending order of the average difficulty level. Next, the lowest comprehension level “1” is assigned to the cluster Ci having the maximum difficulty level. Next, an understanding level “j” is assigned to the cluster Ci having the j-th highest difficulty level. However, j is 1 or more and K or less. The degree of understanding only needs to be defined so as to be uniquely determined with respect to the degree of difficulty, and a method for obtaining the degree of understanding from the degree of difficulty is arbitrary. For example, the reciprocal of the average value of the difficulty level may be used as the degree of understanding. Moreover, you may obtain | require an understanding level from the value after normalization of the average value of difficulty.

  The behavioral pattern data storage unit 15 with subjective evaluation value stores data of a plurality of behavior patterns (behavior pattern data) to which the subjective evaluation value is assigned by the subjective evaluation value giving unit 14. In the behavior pattern data storage unit 15 with a subjective evaluation value, identification information and subjective evaluation values of user behavior data belonging to the cluster Ci are stored as behavior pattern data for each cluster Ci.

As a result, user action data acquisition unit 11 acquires user action data indicating actions taken by the user 40 looking at the English words displayed on the head mounted display 30.

(Step S13) The user behavior data storage unit 12 stores the user behavior data acquired by the user behavior data acquisition unit 11 in step S12 in association with the corresponding difficulty level.

  Here, user behavior data according to the present embodiment will be described. The English word learning program 60 defines an application operation illustrated in FIG. FIG. 7 shows application operations for user actions 1, 2, 3, and the like. For example, when a user action 1 “device turns right” is detected, an application operation “display Japanese translation of English words” is performed. When the user action 2 “device turns to the left” is detected, an application operation “display hints related to English words” is performed. When the user action 3 “device faces down” is detected, the application operation “End English word display” is performed. In the present embodiment, the device refers to the head mounted display 30.

  The user 40 looks at the English words displayed on the head mounted display 30 and takes actions such as user actions 1, 2, 3 and the like. User behavior data indicating the behavior of the user 40 is acquired by the user behavior data acquisition unit 11.

The user action data illustrated in FIG. 8 includes, for each English word, a word identifier (word ID), a difficulty level, a detection value of the sensor unit 34, and user actions 1, 2, and 3 shown in FIG. Etc. (such as the number of times user actions have been performed and the time). By including the actual values of predetermined user actions such as user actions 1, 2, and 3 in the user action data, it becomes easier to cluster the actions of the user 40. Thereby, effects, such as the classification accuracy improvement of the action pattern by the classification | category part 13, are acquired.

(Step S14) It is determined whether or not the presentation of English words to the user 40 has been completed. If completed, the process proceeds to step S15. If not finished yet, the process returns to step S11.

(Step S15) The classification unit 13 classifies the behavior of the user 40 indicated by the user behavior data stored in the user behavior data storage unit 12 into a plurality of behavior patterns.

(Step S16) The difficulty in which the subjective evaluation value assigning unit 14 is associated with the corresponding user behavior data stored in the user behavior data storage unit 12 for each of the plurality of behavior patterns classified in Step S15. Gives understanding based on degree. Data of a plurality of behavior patterns to which the degree of understanding is assigned is stored in the behavior pattern data storage unit 15 with a degree of understanding (subjective evaluation value).

  Next, the determination step will be described (see FIGS. 2 and 4).

(Step S21) An understanding level determination target English word is presented to the user 40. Thereby, an English word presentation timing signal (corresponding to a subjective evaluation value determination target specific type information presentation timing signal) is input to the user behavior data acquisition unit 11.

(Step S22) The user behavior data acquisition unit 11 acquires user behavior data indicating the behavior of the user 40 on which the comprehension level determination target English word is presented, triggered by the input of the English word presentation timing signal. As a result, user behavior data indicating the behaviors of the user behaviors 1, 2, 3, etc., as seen by the user 40 looking at the comprehension-determining target English words displayed on the head-mounted display 30, is obtained from the user behavior data acquisition unit 11.
