[0016] <1> How to select cosmetics and / or beauty treatments (excluding medical procedures) suitable for the subject The present invention is a method for selecting a cosmetic and / or cosmetic method (excluding medical procedures) suitable for a subject, comprising an application step of applying a cosmetic and / or cosmetic method (excluding medical procedures) to a subject, an electroencephalogram acquisition step of acquiring electroencephalograms of the subject after the application step, and a determination step of determining that the cosmetic and / or cosmetic method (excluding medical procedures) is suitable for the subject by applying the electroencephalograms obtained in the electroencephalogram acquisition step to an electroencephalogram index prepared in advance.

[0017] The cosmetic preparation and / or cosmetic method of the present invention (excluding medical procedures) can be applied without any particular limitation as long as it is commonly known.

[0018] Examples of the cosmetic material of the present invention include basic cosmetic materials such as lotions, essences, milky lotions, and creams; makeup cosmetics such as under make-up, emulsion foundations, cheek colors, mascaras, and eyeliners; and hair cosmetics such as hair creams.

[0019] Here, the cosmetic may contain a component that has an effect of improving skin condition.

[0020] Examples of the cosmetic method of the present invention (excluding medical procedures) include face packs, massage techniques, aromatherapy, and the like.

[0021] As described above, in the present invention, the cosmetic method does not include medical procedures. Here, the term "medical procedure" in the present invention refers to the procedure in which a doctor (including a person under the instructions of a doctor) performs surgery, treatment, or diagnosis on a human being.

[0022] Below, we will explain how to select cosmetics and / or beauty treatments (excluding medical procedures) suitable for the subject, with reference to FIG. 1.

[0023] First, in an application step S11, a cosmetic and / or a cosmetic method (excluding medical procedures) is applied to a subject.

[0024] Then, in an electroencephalogram acquisition step S12, an electroencephalogram of the subject is acquired. In the present invention, the method of acquiring an electroencephalogram is not particularly limited, and for example, an earphone-type electroencephalogram acquisition device (VIE ZONE; VIE STYLE Co., Ltd.) can be used to acquire an electroencephalogram.

[0025] The electroencephalogram obtained in the present invention is preferably an electroencephalogram obtained from the external auditory canal. The present invention makes it possible to easily select a cosmetic material and / or a cosmetic method (excluding medical procedures) suitable for a subject by using an electroencephalogram obtained from the ear canal.

[0026] In the present invention, when acquiring electroencephalograms from the external auditory canal, it is preferable to acquire the electroencephalograms using an earphone-type electroencephalogram acquiring device.

[0027] Furthermore, the electroencephalogram in the present invention may be a measured value obtained by measuring the intensity of the electroencephalogram, or may be a time waveform obtained by plotting the intensity of the electroencephalogram. The electroencephalogram in the present invention is preferably a measured value of an electroencephalogram.

[0028] In the determination step S13, the electroencephalogram of the subject acquired in the electroencephalogram acquisition step S12 is applied to an electroencephalogram index prepared in advance. Here, the electroencephalogram index can be obtained by preparing, for example, an electroencephalogram when a cosmetic product and / or a beauty method (excluding medical procedures) suitable for the subject is applied to the subject, an electroencephalogram when the subject is in a mindfulness state, an electroencephalogram when the subject is in a stress state, etc.

[0029] Then, based on the results of applying the subject's brain waves acquired in the brain wave acquisition process S12 to previously prepared brain wave indices, it is determined that the cosmetic and / or beauty method (excluding medical procedures) applied to the subject in the application process S11 is a cosmetic and / or beauty method (excluding medical procedures) suitable for the subject.

[0030] Here, in the present invention, the suitability of a cosmetic and / or a cosmetic method may be judged by a quantitative evaluation, or may be a relative and qualitative evaluation using other cosmetic products as a standard. In the present invention, the index for judgment can be a continuous evaluation axis (for example, any value from 0 to 1, evaluation A to C) for the psychological state from the mindfulness state to the stress state, and the evaluation can be performed.

[0031] The following provides a more detailed explanation of how to determine the suitability of a cosmetic product and / or a cosmetic method.

[0032] In the present invention, when the information acquired in the electroencephalogram acquisition step S12 is a time waveform of an electroencephalogram when a cosmetic product and / or a beauty treatment method (excluding medical procedures) is applied to the subject, When the time waveform of the subject's electroencephalogram acquired in the electroencephalogram acquisition step S12 is similar / close to the mindfulness state reference electroencephalogram obtained in the specific psychological state reference electroencephalogram setting step described below, it can be determined that the cosmetic and / or beauty method (excluding medical procedures) applied to the subject in the application step S11 is a cosmetic and / or beauty method (excluding medical procedures) suitable for the subject.

[0033] In the present invention, when the information acquired in the electroencephalogram acquisition step S12 is a measurement value of an electroencephalogram when a cosmetic product and / or a beauty treatment method (excluding medical procedures) is applied to the subject, When the measured value of the subject's brain waves acquired in the brain wave acquisition step S12 is close to the mindfulness state reference brain waves obtained in the specific psychological state reference brain wave setting step described below, it can be determined that the cosmetic and / or beauty method (excluding medical procedures) applied to the subject in the application step S11 is a cosmetic and / or beauty method (excluding medical procedures) suitable for the subject. Here, "when the value is close to the mindfulness state reference electroencephalogram" preferably means when there is a statistically significant difference between the electroencephalogram measurement value of the subject acquired in the electroencephalogram acquisition step S12 and the electroencephalogram measurement value of the subject in a control state such as a resting state, and the electroencephalogram measurement value of the subject acquired in the electroencephalogram acquisition step S12 is closer to the mindfulness state reference electroencephalogram than the electroencephalogram measurement value of the subject in a control state.

[0034] <2> Preparation of EEG indices Hereinafter, an embodiment in which the electroencephalogram indices are prepared in advance will be described with reference to Fig. 2. Note that the description of the electroencephalogram acquiring step S12 is cited for the method of acquiring the electroencephalogram.

[0035] In the present invention, it is preferable that the electroencephalogram index is prepared by a method having a specific psychological state inducing step S21 of applying any specific psychological state inducing stimulus (excluding medical procedures) to induce the same subject as in the selection method into a specific psychological state, a specific psychological state electroencephalogram acquiring step S22 of acquiring the electroencephalogram of the subject after the specific psychological state inducing step S21 by the same method as in the electroencephalogram acquiring step, and a specific psychological state reference electroencephalogram setting step S23 of setting the electroencephalogram in the specific psychological state electroencephalogram acquiring step S22 as a specific psychological state reference electroencephalogram.

[0036] First, in a specific psychological state inducing step S21, a specific psychological state inducing stimulus (excluding medical procedures) for inducing the subject into a specific psychological state is applied to the subject.

[0037] The "specific psychological state" in the present invention is preferably a mindfulness state and / or a stress state.

[0038] In the present invention, the term "mindfulness state" means that the subject is in a meditative state, preferably an insightful meditative state, which may also be called a drowsy state.

[0039] In the present invention, the "stress state" refers to a state in which the subject feels a decrease in vitality, irritation, anxiety, depression, and the like.

[0040] In the present invention, the "specific psychological state inducing stimulus (excluding medical procedures)" can be applied without any particular limitation as long as it is a stimulus (excluding medical procedures) that can induce the subject into a specific psychological state.

[0041] When the specific psychological state is a mindfulness state, examples of the "specific psychological state inducing stimulus (excluding medical procedures)" include music, sound, scent, images, movement, breathing techniques, massage, touch, temperature, humidity, etc. (excluding medical procedures) that are known to induce the subject into a meditative state, and recollection of a memory or episode that the subject understands as being able to induce him or her into a meditative state.

[0042] Furthermore, when the specific psychological state is a mindfulness state, the "specific psychological state inducing stimulus (excluding medical procedures)" may be a cosmetic product known to have the effect of inducing a subject into a meditative state. The preferred form of the cosmetic product is as described above.

[0043] When the specific psychological state is a stressful state, examples of the "specific psychological state inducing stimulus (excluding medical procedures)" include music, sounds, scents, images, movements, textures, temperature, humidity, etc. (excluding medical procedures) that are known to induce a stressful state in the subject, and recollection of memories or episodes that the subject understands as being able to induce the subject into a stressful state.

[0044] Then, in a specific psychological state electroencephalogram acquisition step S22, an electroencephalogram of the subject to which a specific psychological state inducing stimulus (excluding medical procedures) has been applied is acquired. The electroencephalogram acquired in the specific psychological state electroencephalogram acquiring step S22 is preferably a measured value of the electroencephalogram.

[0045] Thereafter, in a specific psychological state reference electroencephalogram setting step S23, the electroencephalogram of the subject acquired in the specific psychological state electroencephalogram acquisition step S22 is set as a specific psychological state reference electroencephalogram.

[0046] The electroencephalogram index may be prepared as a reference electroencephalogram for a particular psychological state by combining an electroencephalogram when in a mindfulness state with an electroencephalogram when in a stress state.

[0047] Now, if a particular psychological state is a mindfulness state, It is preferable that the electroencephalogram index is prepared by a method having a mindfulness state induction step of applying any mindfulness state induction stimulus (excluding medical procedures) to induce the same subject as in the selection method into a mindfulness state, a mindfulness state electroencephalogram acquisition step of acquiring the electroencephalograms of the subject after the mindfulness state induction step by the same method as in the electroencephalogram acquisition step, and a mindfulness state reference electroencephalogram setting step of setting the electroencephalograms in the mindfulness state electroencephalogram acquisition step as mindfulness state reference electroencephalograms.

[0048] Also, if a particular psychological state is stressful, It is preferable that the EEG index is prepared by a method having a stress state induction step of applying any stress state inducing stimulus (excluding medical procedures) to induce the same subject as in the selection method into a stress state, a stress state EEG acquisition step of acquiring the subject's EEG after the stress state induction step by the same method as in the EEG acquisition step, and a stress state reference EEG setting step of setting the EEG in the stress state EEG acquisition step as a stress state reference EEG.

[0049] By using the reference electroencephalogram of the specific psychological state of the subject prepared in this manner as the electroencephalogram index, it is possible to select cosmetics and / or beauty treatments (excluding medical procedures) that are suitable for the subject. Furthermore, according to the present invention, it is possible to provide a method for selecting cosmetics and / or beauty treatments (excluding medical procedures) that are more suitable for a personal prescription, in the sense of cosmetics and / or beauty treatments (excluding medical procedures) that are tailored to each individual.

[0050] In the present invention, the specific psychological state reference electroencephalogram setting step S23 is preferably repeated at least twice, more preferably at least three times, to obtain the electroencephalogram index. Specifically, it is preferable to repeatedly measure the electroencephalogram when in a mindfulness state and / or the electroencephalogram when in a stress state. By adopting the above-mentioned form, it is possible to select cosmetics and / or beauty treatments (excluding medical procedures) that are suitable for the subject with greater accuracy.

[0051] In the present invention, the specific psychological state reference electroencephalogram may be calculated using a learning device equipped with a trained model constructed by performing a learning process using a learning data set.

[0052] The training data set is a training data set in which the electroencephalograms of the subject are associated with the degree of a specific psychological state corresponding to the data relating to the electroencephalograms.

[0053] It is preferable that the trained model is constructed by a model construction means (not shown). The model construction means performs a learning process using a learning data set based on the collected data in a machine learning model, and constructs a trained model.

[0054] Furthermore, the learning data set may include collected data that has been subjected to data pre-processing such as data shaping, or may include collected data that has been normalized. The learning dataset is collected data that has been annotated, and the probability or the presence or absence of the subject's state (mindfulness state, stress state) is associated with a combination of various data constituting the collected data (electroencephalogram). Note that the model construction means may perform fine tuning when constructing the trained model, and may adjust hyperparameters of the machine learning model.

[0055] Here, the machine learning model may be selected from a group including neural network models such as a convolutional neural network model, a recurrent neural network, etc. In this case, the machine learning model is not limited in the number of layers, the type of the activation function, or the type of the model, and any known or conventional method may be appropriately adopted.

[0056] By using a learning device equipped with a trained model, the psychological state from the mindfulness state to the stress state can be evaluated on a continuous evaluation axis (e.g., any value between 0 and 1, or a rating of A to C), making it possible to select cosmetics and / or beauty methods that are suitable for the subject with greater certainty.

[0057] <3> A selection device for selecting cosmetics and / or beauty treatments (excluding medical procedures) suitable for the subject The selection device of the present invention for selecting a cosmetic product and / or a cosmetic method (excluding medical procedures) suitable for a subject will be described below with reference to FIG. <1> The present invention relates to an apparatus for implementing the selection method described above. <1> The explanation in item (1) also applies to the selection device described below.

[0058] The selection device 1 of the present invention comprises an electroencephalogram acquisition means 12 for acquiring electroencephalograms of a subject after applying cosmetics and / or a beauty treatment method (excluding medical procedures) to the subject, and a determination means 111 for determining that the cosmetics and / or beauty treatment method (excluding medical procedures) are suitable for the subject by applying the electroencephalograms of the subject acquired by the electroencephalogram acquisition means 12 to electroencephalogram indices of the subject prepared in advance.

[0059] As shown in FIG. 3, the selection device 1 includes a CPU (Central Processing Unit) 11 having a determination means 111, an electroencephalogram acquisition means 12, a ROM (Read Only Memory) 13 having a storage means 131, and a determination result display unit .

[0060] The storage means 131 stores the electroencephalogram indices of the subject that are prepared in advance.

[0061] The judgment result display unit 14 is preferably a display that displays the result of the judgment made by the judgment means 111 .

[0062] The selection device 1 configured in this way can easily determine that a cosmetic product and / or a beauty method (excluding medical procedures) is suitable for the subject, simply by measuring the subject's brain waves.

[0063] In addition, in another embodiment, instead of the electroencephalogram acquiring means 12, an electroencephalogram measurement value input section may be provided for inputting the measurement value of the electroencephalogram of the subject, which is separately measured.

[0064] In this embodiment, the selection device 1 is configured to include all of the above-mentioned means. Here, in the present invention, each of the above means may be realized by an individual device, and further, each means and each storage unit may be realized by a different device, and each functional configuration may be realized by a group of devices of an arbitrary configuration.

[0065] <4> A selection program in which subjects select cosmetics and / or beauty methods (excluding medical procedures) that are appropriate for them The present invention also relates to a selection program for causing a computer to execute the above-mentioned method for selecting cosmetics and / or beauty treatments (excluding medical procedures) suitable for a subject. The program of the present invention will be described with reference to the symbols in Fig. 3, since each unit in the CPU included in the above-mentioned selection device of the present invention corresponds to each unit.

[0066] The selection program of the present invention causes a computer to function as a determination means 111 that determines that a cosmetic and / or beauty method (excluding medical procedures) is suitable for a subject by applying the measured electroencephalogram of the subject after the cosmetic and / or beauty method (excluding medical procedures) is applied to the subject to pre-prepared electroencephalogram indices of the subject. EXAMPLES

[0067] <Preparation of EEG indices> (1) Setting the Mindfulness State Reference EEG Waves (1-1) Mindfulness state induction process First, the subjects were induced into a mindfulness state by following audio instructions for mindfulness meditation (Mindfulness Leadership Institute, General Incorporated Association) for 10 minutes.

[0068] (1-2) Mindfulness state EEG acquisition process The time waveform of the subject's electroencephalogram in (1-1) above was obtained using an earphone-type electroencephalogram acquisition device (VIE ZONE; VIE STYLE Co., Ltd.).

[0069] (1-3) Mindfulness state reference EEG setting process The time waveform (collected data) of the subject's EEG obtained in (1-2) above was applied to a trained model constructed by performing a learning process using a training dataset that matches the time waveform (collected data) of the subject's EEG with the probability of the subject's state (mindfulness state) or the presence or absence of such a state. By applying the time waveform (collected data) of the subject's EEG to the above trained model, a reference EEG for the subject's mindfulness state was obtained.

[0070] At this time, the mindfulness state reference electroencephalogram when the subject is induced into the mindfulness state can be set to 1 (corresponding to the electroencephalogram index in the present invention; see FIG. 4).

[0071] (2) Setting the reference brainwaves in stress states (2-1) Stress state induction process Next, the subjects were asked to recall an episode that reminded them of anger or irritation, and the subjects were induced into a non-mindfulness state, preferably a stressful state (although it is difficult to say that this was definitely a mindfulness state).

[0072] (2-2) Stress state EEG acquisition process The time waveform of the subject's electroencephalogram in (2-1) above was obtained using an earphone-type electroencephalogram acquisition device (VIE ZONE; VIE STYLE Co., Ltd.).

[0073] (2-3) Stress state reference EEG setting process The time waveform (collected data) of the subject's EEG obtained in (2-2) above was applied to a trained model constructed by performing a learning process using a learning dataset that matches the time waveform (collected data) of the subject's EEG with the probability of the subject's state (stress state) or the presence or absence of such a state. By applying the time waveform (collected data) of the subject's EEG to the above trained model, a reference EEG for the subject's stress state was obtained.

[0074] At this time, the stress state reference electroencephalogram when the subject is induced into a stress state can be set to 0 (corresponding to the electroencephalogram index in the present invention; see FIG. 4).

[0075] In this embodiment, (1) the mindfulness state reference electroencephalogram setting process and (2) the stress state reference electroencephalogram setting process were repeated twice to obtain electroencephalogram indices (see FIG. 4).

[0076] <Selection of cosmetics and / or beauty methods (excluding medical procedures) applied to subjects: Screening> Hereinafter, a method for determining the suitability of a cosmetic product and / or a cosmetic method (excluding medical procedures) applied to a subject based on the above electroencephalogram indices will be described.

[0077] (3) Method of selection of cosmetics and / or beauty treatments (excluding medical procedures) applied to subjects (3-1) Applicable process First, the cosmetic product and / or beauty method (excluding medical procedures) to be evaluated is applied to the subject.

[0078] (3-2) EEG acquisition process Next, the time waveform of the subject's electroencephalogram after the application step is acquired using an earphone-type electroencephalogram acquisition device (VIE ZONE; VIE STYLE Co., Ltd.).

[0079] (3-3) Judgment process Finally, the data (EEG) collected in the EEG acquisition process was applied to the trained model used in (1) and (2) and compared with the subject's EEG indices prepared in advance in (1) and (2).

[0080] Here, the further the brain waves in the brain wave acquisition process are from the stress state reference brain waves (the aforementioned "0") and the closer they are to the mindfulness state reference brain waves (the aforementioned "1"), the more the cosmetic and / or beauty method (excluding medical procedures) being evaluated can be determined to be a cosmetic and / or beauty method (excluding medical procedures) that is suitable for the subject. [Industrial Applicability]

[0081] The present invention can be used in a method for selecting a cosmetic and / or a cosmetic method (excluding medical procedures) suitable for a subject. [Explanation of symbols]
