Anxiety and stress are increasing due to the occurrence of various social problems such as the rapidly changing social environment of modern society, excessive competition, dehumanization, social and psychological crimes, the emergence of contagious diseases and aging, which are factors that greatly threaten mental and physical health. It's working.

In particular, after the general public experienced emotional stress such as anxiety and despair due to infectious diseases such as swine flu, SARS, and MERS a few years ago, the recent pandemic situation such as Corona 19 (COVID-19) has made the public feel an unprecedented 'social distance'. The quality of life is greatly deteriorated due to the stress caused by experiencing 'putting'. In addition, the emergence of these infectious diseases leads to restrictions on the use of religious facilities, entertainment facilities, and sports facilities, which change the daily life of our people and seriously affect the increase in stress and anxiety.

In this situation, students have difficulties in participating in classes and adapting to class progress due to the new and changed learning management system, such as the postponement of the start of classes due to the inability of face-to-face classes and the replacement of face-to-face classes with non-face-to-face remote classes. has been reported to feel

In a situation where there are many difficulties due to increased social stress, continuous stress exposure may physiologically increase heart rate and blood pressure, as well as the cardiovascular system, as well as changes in the digestive system and increase in muscle tension, and psychologically, depression and anger. , excitement, emotional instability, and nervousness.

Exposure to these stressors can lead to increased anxiety and depression if not immediately resolved, chronically, or dealt with in an inappropriate way, which not only increases national medical expenses and lowers the quality of life of the people, but also affects disease morbidity. Therefore, appropriate interventions for stress relief are needed.

Recently, as programs and interventions to relieve stress, a Mind-fullness-Based Stress Reduction (MBSR) program, a type of meditation training, a composite art education program that combines choral singing and breathing training, and aroma essential oil There are research results and reports that aromatherapy foot baths are helpful in reducing stress and calming down.

However, since the MBSR program can only be conducted by experts who have completed a trained instructor course, it is not only difficult to access and it is not easy to relieve stress immediately. It is difficult to apply because of its limited effect. In addition, aromatherapy foot bath is also a stress relief method that is difficult to use in everyday life because there is a limit to immediate application when exposed to a stress source.

Figure 2 is a block diagram showing the configuration and connection relationship according to an embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings, the configuration of the stress relief system of the wearable device interlocking method of the present invention will be described in detail.

1 is a conceptual diagram of the present invention, which can be efficiently applied without time and place limitations when exposed to a stress source as an auditory-based stress mediation method.

In particular, auditory-based devices are very accessible due to the recent spread of smartphones and the increase in the use of various apps that support sound source playback, etc., and are very economical in terms of cost and complementary and alternative therapy with little side effects.

In addition, listening to music has the characteristic of inducing an alpha wave state by directly affecting brain conduction, stabilizing a person, and inducing relaxation of mental and physical tension. has the effect of causing

In addition, previous studies have shown that listening to music directly affects the brain and autonomic nervous system, causing physiological changes and reactions, and has positive effects such as relieving tension, relieving stress, and reducing anxiety, as well as improving concentration. It is becoming.

The present invention is a technology that applies the Healing Rhythm system as an intervention. It is an intervention method that induces sedation in a stressful situation in stages by an intervention method supplemented and applied by extracting the ECG waveform and the same sound wave.

2 is a block diagram showing the configuration and connection relationship according to an embodiment of the present invention. For the aforementioned functions, the present invention includes a wearable device 110, an analysis module 120, and a monitoring module 130 as main components. ), a sound source control module 140, an output module 150, a support module 160 for supporting additional functions, and a recommendation module 170.

The wearable device 110 is worn on the body by the user and is configured to measure the user's behavior or posture determined based on biometric information represented by heart rate and electrocardiogram signals and the user's location or device, including a wristwatch, It can be configured to be worn on the body in various forms, such as bracelets, anklets, necklaces, canes or other types of portable devices, and when necessary, devices that can be in contact with the body.

The wearable device 110 includes a first sensor unit 111 that measures heart rate and electrocardiogram signals through electrodes installed on the body contact part, and a second sensor unit 112 that measures user's location and behavioral information. ) is provided.

The first sensor unit 111 is configured to induce the action current generated in the myocardium according to the heartbeat to two suitable places on the body surface, record it with an ammeter, and obtain a record of the myocardial action current. In the present invention, the measured An ECG waveform acts as a very important factor in an ECG signal.

1 includes a graph showing a typical electrocardiogram waveform, P in the curve represents atrial contraction, and QRST is derived from ventricular contraction.

At this time, the interval of PQ shows the time when excitation occurs in the sinus node and is conducted to the atrioventricular node of the stimulation conduction system.

In addition, in the QRS group, R shows the largest voltage change as it coincides with the beginning of the heartbeat and the first heart sound in terms of time, and the part between S and T is when the entire ventricle is contracting on average. , the elevation of T occurs because the contraction of the base of the heart remains even when the contraction of the apex ends. The end of T coincides in time with the beginning of the second heart sound.

The second sensor unit 112 basically consists of a GPS module, an IMU sensor, or a 3-axis acceleration sensor, and measures the user's position, attitude change, change speed for position movement, and displacement amount. Basically, it is possible to identify where the user is moving in which direction, in which direction and at what speed, information related to major actions such as walking or running, as well as sitting or standing, can be identified as behavioral information.

The analysis module 120 is a component that collects and analyzes waveform information including the amplitude and frequency of a heartbeat through the measured electrocardiogram signal and extracts waveform information of a psychological stability period. In order to obtain an ECG signal in a stable state or a state maximally close thereto, it is preferable to obtain an ECG signal determined to be in the most stable state through a number of measurements over time in a state in which a stress source is removed. In addition, as will be described later, a signal determined to be in the most stable state may be used from ECG signals measured at all times, and ECG waveform information is extracted from the ECG signal of the psychological stability period.

The monitoring module 130 is a component that analyzes the user's location and behavioral information measured through the second sensor unit 112 to determine an operating mode based on a life pattern. Various operation modes can be set, and the present invention suggests a sleep mode, an exercise mode, a concentration mode, and a stress relief mode as preferred modes for applying the healing beat. It provides a mode that helps sleep, a mode that helps during exercise and recovery, a mode that helps improve concentration during study or work, and a mode that helps relieve stress in various stress situations.

That is, the behavioral information is information that includes what actions the user performs at which position, and in particular, the operation in each situation is based on situations such as sleep, exercise, and learning to which the present invention can be effectively applied among life patterns. mode can be set.

If it is difficult to grasp a standardized behavioral pattern, the corresponding operation mode can be set by allowing the user to directly input a situation requiring study, exercise, sleep, or stress relief.

Basically, each operation mode is the same in that it outputs the sound source processed through the waveform information of the psychological stabilizer, but it can be output with a different type of sound source, playback time, and change in playback volume.

For example, in the concentration mode, the user is configured to maintain the same volume for the set time corresponding to the sound source so that the user can listen to the sound source to the end. It may be configured so that volume control is performed in a manner of fading out within a set time. In this case, a lullaby or a calm sound source is also applied to the genre of the sound source.

On the other hand, in the case of the exercise mode, sound sources with fast beats and vigorously repeated rhythms can be applied to improve the exercise effect, and in the case of stress relief mode, sound sources of a wider range of genres can be provided by reflecting the user's taste.

The sound source control module 140 is configured to process the same sound source as the BPM according to the waveform information of the psychological stabilizer from the management of the sound source by reflecting the sound wave information, and includes a sound wave generator 141 and a sound source processing unit 142 and a sound source management unit 143, an exercise mode support unit 144 and a sleep mode support unit 145.

The sound wave generator 141 is a component that generates sound wave information by extracting a feature vector for the amplitude and frequency of the waveform information of the stabilizer, and analyzes the normal rhythm P-QRS-T waveform change of the electrocardiogram in the user's stable state. After extracting the feature vector for the amplitude and frequency, it is converted into the same sound wave.

The sound source processing unit 142 is configured to process the sound wave information to be reflected in a sound source having the same BPM as the heart rate of the psychological stabilizer according to the operation mode. To this end, a method of receiving and storing a plurality of sound sources having BPM within a set range or artificially adjusting the speed of a specific sound source to have a set BPM may be used. In addition, the sound source is processed by reflecting the sound wave generated by the sound wave generator 141, and the sound wave characteristics of the sound source are processed to be the same as the sound wave extracted from the feature vector of the user's resting heart rate waveform.

The sound source management unit 143 controls the type of sound source and output time according to the set operation mode, classifies the type of sound source that can be output for each set operation mode, presents a list, and as mentioned above, Depending on the playback time, the volume control is changed.

In particular, in the present invention, it can be applied as a method of increasing the BPM step by step to increase the exercise effect in the exercise mode and lowering the BPM again after the exercise is over.

To this end, the exercise mode support unit 144 provides a function of increasing the BPM of the sound source to a set value during exercise and lowering the BPM of the sound source to the BPM of the resting heart rate for a target time after exercise. At this time, the highest BPM, steps for ascending and descending, and sound source playback time for each step can be individually set according to the exercise program.

The sleep mode support unit 145 is a component for inducing deeper sleep and improving the quality of sleep by controlling the playback time and volume of the sound source as the user enters the sleep state during the aforementioned sleep mode. After analyzing the real-time change of the electrocardiogram signal collected through the first sensor unit during the operating time of the output module, when it is determined as a stable sleep progression range, the sound source output time is reset and the volume corresponding to the output time is faded out by reflecting the change speed Control the change to happen.

That is, real-time changes in the user's electrocardiogram signal are analyzed during the output time of the sound source in the sleep mode, and when the user enters sleep normally, the electrocardiogram changes are alleviated the same as during sleep.

Depending on the person, the changes in the electrocardiogram during sleep may vary slightly, but basically, it is common to show a pattern of gradually decreasing until falling into deep sleep and then recovering gradually until waking up, or continuously falling until waking up. may rise for a certain period of time when going to bed late or when melatonin is initially excessively secreted to help sleep, out of the usual pattern.

Preferably, it is determined that sleep is progressing by measuring and applying the heart rate during stable sleep of the individual in advance or by comparing it with the resting electrocardiogram. If dreaming or REM sleep disorder results in an unstable electrocardiogram, it is necessary to continuously secure the playing time of the sound source even during actual sleep.

Then, when it is determined as a stable sleep progress range as a result of electrocardiogram signal analysis, the sound source output time is reset by reflecting the change speed, and the volume fade-out change corresponding to the reset output time is controlled.

In other words, when the volume is not properly controlled when you go to sleep, playing the sound source may rather interfere with the improvement of the quality of sleep. Therefore, when entering into a stable sleep state is confirmed, gradually reduce the volume and stop playing the sound source, so that stable sleep can continue. do.

At this time, when the speed of ECG change is reflected and stabilization is fast, the volume fades out and the sound source playback stops within a short time. In the case of slow stabilization, the volume fades out and the sound source playback stops over a relatively long period of time. there is In other words, a slow stabilization speed means that it takes more time to fall asleep, which means that there is a high risk of waking up from sleep easily due to changes in the surrounding environment in a sensitive state.

Therefore, it is desirable to fade out the volume over the set time by applying a time equal to or a set time proportional to the time from the beginning of the sound source playback to the point of stabilization of the ECG signal, and to stop playing the sound source at the point when the final volume reaches 0. do.

The output module 150 is configured to output the processed sound source so that the user can hear it, and can basically correspond to a speaker, earphone, or headphone. Preferably, bone conduction earphones can be used, and a linked operation with a separate audio system is also possible, and the sound source processed through the sound source control module 140 is output at an appropriate volume so that the user can hear it.

The support module 160 is a configuration for analyzing and controlling stress in connection with the user's behavioral information, and includes a pattern generator 161, a recognition unit 162, a reset unit 163, and operation as detailed configurations. A recommendation unit 164 is provided.

The subject of the present invention, that is, most of the users wearing the wearable device 110 have behavioral patterns by time including a moving path, and each user has a unique activity range and behavioral habits. The pattern generation unit 161 is to identify such a pattern through the accumulated ECG signal behavioral information, and analyzes the collected ECG behavioral information to obtain life pattern information reflecting frequently traveled routes and behavioral habits through analysis. is created In particular, in the case of students or office workers during the semester, life pattern information at school or work other than personal life is generated.

The recognition unit 162 is a component that recognizes a stress change situation in real time through a change in heart rate. In other words, by determining the stress change factor corresponding to the behavioral state, it is possible to recognize stressful situations in various daily activities, including school or work, and to check behavioral information corresponding to this, or in unusual situations that are different from the behavioral information collected normally. Behavioral information reflecting the is confirmed.

The resetting unit 163 is a component that analyzes the generated life pattern information in association with real-time stress change and behavior information, and then generates reference information that can be determined as a stable period by the analysis module. That is, as the stress change recognized through the aforementioned cognitive unit 162, that is, the increase in stress determined through an increase in heart rate and the specific behavioral state collected through the second sensor unit 112 accumulate, it is analyzed correlations can be derived. In addition, the reset unit 163 connects the generated life pattern information with real-time stress changes and behavior information to generate reference information for the analysis module 120 to determine as a stable period.

As mentioned above, the analysis module 120 may generate reference information in advance in a specific situation in which a stress source is blocked, but it is determined that the user is in a psychologically stable state through information collected during daily life, and through this, the reference information can also create

The motion recommendation unit 164 is configured to present a recommended mode and a sound source to the user's real-time stress change and behavioral information. In particular, in the case of real-time stress changes and behavioral information learning or work-related situations, the concentration mode, in the case of other forms of stress, the sound source can be recommended according to the stress relief mode, and in the situation of rest, the sleep mode And a corresponding sound source may be recommended.

The recommendation module 170 compares and analyzes stress-related evaluation results from users, data collected from a plurality of users having the same or similar physical and occupational conditions, and results according to the application of the present invention to provide more accurate status identification and customized therapy. As a configuration to support the progress, a personal information input unit 171, an evaluation input unit 172, an information management unit 173, and a sound source recommendation unit 174 are provided as detailed configurations.

The personal information input unit 171 is a component that receives personal information including the user's age, gender, occupation, life, and physical conditions.

The above personal information includes the user's gender and age, as well as physical conditions related to various medical conditions that can lead to stress, as well as contents related to daily life patterns such as work, study, and hobbies, or in the case of jobs, work types, work hours, and workload, etc. Subdivided management can be performed by receiving conditions. In particular, in the case of a job, the type of work, working hours and workload may include the range of hours of work and rest, whether the work type is full-time or part-time, day or night work, and the like.

The evaluation input unit 172 is configured to receive evaluation information including current stress, emotion, sleep quality, and amount of exercise as a score obtained by measuring positive and negative values from the user. In other words, you can receive questions and answers on a scale of 3 to 10 points, and you can receive evaluation information through the linked web or application.

For the main question, the evaluation of information including current stress, current mood, sleep evaluation, and amount of exercise is input as a subjective numerical index, and based on the midpoint of the total score, whether positive or negative was evaluated. to judge

The information management unit 173 is configured to accumulate the personal information and evaluation information to form groups for each condition, and classifies users having the same or similar age group, gender, occupational group, and other similar information into groups, in particular, Each user's stabilizer BPM is classified and managed together.
