It can be performed in

First, the psychological control device can acquire biometric information, which is information related to the user's biological state to estimate the user's psychological state, through a sensing module included in the psychological control device (S310).

Here, the specific process of acquiring biometric information, which is information related to the biological state for estimating the psychological state of the user, in the psychological control device through the sensing module included in the psychological control device will be described in more detail with reference to FIG. 4 below. You can.

Figure 4 is a flowchart illustrating a method of obtaining biometric information in a psychological control method based on biometric information according to an embodiment of the present invention.

Referring to FIG. 4, a psychological control device that performs a psychological control method based on biometric information according to an embodiment of the present invention measures the user's electrodermal activity (EDA) based on a first sensing module, which is one of the sensing modules. Information about and the user's body temperature can be obtained (S311).

Specifically, the psychological control device may include a plurality of sensing modules capable of detecting changes in the state of the user's body.

For example, the plurality of sensing modules include a skin conductance sensing module, an electrocardiogram (ECG) sensing module, a photoplethysmogram (PPG) sensing module, a respiration rate (RESP) sensing module, and a thermal sensing module. , heart rate variability (HRV) sensing module, etc.

Here, the first sensing module among the plurality of sensing modules included in the psychological control device refers to a skin conductance sensing module capable of determining the value of the user's skin conductance and a body temperature sensing module capable of determining the value of the user's body temperature. can do. Specifically, the value of skin conductance for the user determined by the first sensing module may mean information about the user's skin conductance, and the value of body temperature for the user determined by the first sensing module may be the user's body temperature. It can mean information about.

Afterwards, the psychological control device may acquire information about the user's heart rate variability (HRV) based on the second sensing module, which is one of the sensing modules (S312).

Here, the second sensing module among the plurality of sensing modules included in the psychological control device may refer to a heart rate variability sensing module capable of determining the value of the user's heart rate variability, and more specifically, by the second sensing module. The determined heart rate variability value for the user may mean information about the user's heart rate variability.

Thereafter, the psychological control device can acquire biometric information about the user by setting it to include information about the obtained skin conductance, information about the obtained body temperature, and information about the obtained heart rate variability (S313).

In other words, the psychological control device converts information about skin conductance obtained about the user, information about body temperature obtained about the user, and information about heart rate variability obtained about the user into biometric information about the user using the psychological control device. A decision can be made, and biometric information about the determined user can be obtained.

Again, referring to FIG. 3, a psychological control device that performs a psychological control method based on biometric information according to an embodiment of the present invention measures the arousal and valence of the user's psychology based on the acquired biometric information. ) can be analyzed to infer the user's psychological state (S320).

Here, the specific process of inferring the user's psychological state by analyzing the psychological arousal and favorability of the user based on the biometric information obtained about the user using the psychological control device in the psychological control device, see FIG. 5 below. This can be explained in more detail.

Figure 5 is a flowchart illustrating a method for estimating a psychological state in a psychological control method based on biometric information according to an embodiment of the present invention.

Referring to Figure 5, a psychological control device that performs a psychological control method based on biometric information according to an embodiment of the present invention is based on information about the user's skin conductance and body temperature obtained for the user. Arousal, which refers to the degree of arousal related to the psychological state, can be determined (S321).

Specifically, the psychological control device can confirm the value of the user's skin conductance through information about the user's skin conductance, and determines the value of the height of arousal for the user based on the size of the confirmed skin conductance value of the user. You can judge.

For example, the psychological control device may determine that the higher the skin conductance value for the user is, the more sweat, etc., is formed on the user's skin. This may determine that the user is psychologically tense and the degree of arousal is high. You can. Accordingly, the psychological control device can determine that the higher the skin conductance value for the user, the higher the level of arousal for the user.

Additionally, the psychological control device can check the value of the user's body temperature through information about the user's body temperature and determine the value of the height of the user's arousal based on the size of the user's body temperature value.

For example, the psychological control device may determine that the greater the value of the user's body temperature, the higher the level of psychological tension and arousal in the user. Accordingly, the psychological control device may determine that the higher the value of the user's body temperature, the higher the level of arousal for the user.

Thereafter, the psychological control device may determine liking, which means the degree of liking related to the user's psychological state, based on information about the user's heart rate variability obtained for the user (S322).

Specifically, the psychological control device can confirm the value of the user's heart rate variability through information about the user's heart rate variability, and determines the value of the increase or decrease in favorability for the user based on the size of the confirmed user's heart rate variability value. You can judge.

For example, the psychological control device may determine that the higher the heart rate variability value for the user, the faster the user's heart beats, which indicates that the user has a high level of liking due to the psychological sense of relaxation or stress. can do. Accordingly, the psychological control device may determine that the greater the heart rate variability value for the user, the greater the increase in liking for the user.

Thereafter, the psychological control device may determine a psychological state value corresponding to the determined arousal and the determined likeability for the user among a plurality of psychological state values representing the user's psychological state (S323).

Here, the specific process of determining the psychological state value corresponding to the determined arousal and the determined favorability for the user among a plurality of psychological state values representing the user's psychological state in the psychological control device is described in more detail below with reference to FIG. 6. It can be explained clearly.

Figure 6 is a flowchart illustrating a method of determining a psychological state value in a psychological control method based on biometric information according to an embodiment of the present invention.

Referring to FIG. 6, a psychological control device that performs a psychological control method based on biometric information according to an embodiment of the present invention divides the range of values in which arousal changes by the size of a preset value to distinguish psychological state values. Multiple awakening areas used for this purpose can be created (S323-1).

Specifically, the psychological control device can check the lowest and highest values at which the user's arousal can change, and determine the range between the lowest and the highest values as the range of values at which the user's arousal can change. In other words, the psychological control device can generally determine the range in which arousal can be changed corresponding to the range in which the value of skin conductance can be changed and the range in which the value of body temperature can be changed.

For example, the psychological control device can collect information about the user's age and gender in advance, and the change range of average skin conductance and average body temperature are pre-matched based on the information about the user's age and gender, etc. collected in advance. You can check information about the scope of change. That is, the psychological control device may have information on the range of change in average skin conductance and the range of change in average body temperature pre-matched based on information about the user's age and gender.

Thereafter, the psychological control device may divide the entire range of the determined arousal level based on the size of a preset value, thereby creating a plurality of arousal areas with different ranges of the arousal value. In other words, the psychological control device can create a plurality of arousal areas that can be used as a standard for distinguishing the degree to which the user is aroused.

Afterwards, the psychological control device can divide the range of values in which favorability changes into the size of a preset value to create a plurality of favorability areas used to distinguish psychological state values (S323-2).

Specifically, the psychological control device can check between the lowest and highest values at which the user's favorability can change, and can determine the range between the lowest and highest values as the range of values at which the user's favorability can change. In other words, the psychological control device can generally determine the range in which liking can be changed corresponding to the range in which the value of heart rate variability can change.

For example, the psychological control device may collect information about the user's age and gender in advance, and may collect information about the range of change in average heart rate variability that is pre-matched based on the pre-collected information about the user's age and gender. You can check it. That is, the psychological control device may have information about the range of change in average heart rate variability pre-matched based on information about the user's age and gender stored in advance.

Afterwards, the psychological control device can divide the entire range of the judged likeability based on the size of a preset value, and thereby create a plurality of likeable areas with different ranges of likeability values. In other words, the psychological control device can create a plurality of liking areas that can be used as a standard for distinguishing the user's liking level.

Here, the sizes of preset values used to create a plurality of arousal areas and a plurality of liking areas in the psychological control device may be the same, but may not necessarily be limited thereto. That is, the sizes of preset values used to create a plurality of arousal areas and a plurality of liking areas in the psychological control device may not be the same.

Thereafter, the psychological control device may match the user's psychological state value to a plurality of psychological regions divided based on the plurality of generated arousal regions and the plurality of generated liking regions (S323-3).

Specifically, the psychological control device can set the overall value range in which arousal changes and the overall value range in which favorability changes as the overall area. Thereafter, the psychological control device may divide the overall area set based on the overall value range into a plurality of arousal areas and a plurality of liking areas. Thereafter, the psychological control device may determine a plurality of areas divided based on a plurality of arousal areas and a plurality of liking areas into a plurality of psychological areas used to distinguish the user's psychological state.

Thereafter, the psychological adjustment device may match the user's psychological state value corresponding to the determined plurality of psychological areas. For example, the user's psychological state values corresponding to the plurality of psychological domains determined by the psychological control device may be 'surprised', 'angry', 'sad', 'excited', 'happy' and 'calm', etc. It can refer to a value that can represent a person's psychological state.

At this time, the psychological control device can match the values of psychological states with a high degree of arousal, such as 'surprise' and 'excited', to a plurality of psychological areas with a high arousal value, and a plurality of psychological areas with a medium arousal value. In psychological domains, values of psychological states with a medium level of arousal, such as 'angry' and 'happy', can be matched, and in multiple psychological domains with low arousal values, such as 'sadness' and 'calm'. It is possible to match the value of a psychological state with a low arousal value.

Meanwhile, the psychological control device can match the values of negative psychological states, such as 'surprise', 'angry', and 'sadness', to a plurality of psychological areas with low likability values, and to a plurality of psychological areas with high likability values. Values can be matched to positive psychological states such as 'excited', 'happy', and 'calm'.

Thereafter, the psychological control device may extract the matched psychological state value corresponding to the area of the determined arousal and the judged likability for the user among the plurality of psychological state values generated through matching (S323-4).

Specifically, the psychological control device may identify an area corresponding to the arousal value determined for the user and an area corresponding to the likability value determined for the user in the overall area set based on the overall value range. Afterwards, the psychological control device can extract the psychological state value matched to the identified area as a psychological state value corresponding to the user's arousal and likability.

For example, the psychological control device may generate a psychological state value for a user that has been previously matched to an area identified based on an area corresponding to the value of arousal determined for the user and an area corresponding to the value of likability judged for the user. In the case of 'surprise', the psychological state value 'surprise' can be extracted.

Thereafter, the psychological control device may determine the extracted psychological state value as a psychological state value corresponding to the arousal and favorability obtained for the user using the psychological control device (S323-5).
