Biofeedback measures the body and mind response through the bio attachment sensor and informs the measured information to the patient in the form of sounds or graphs that can be perceived by the patient so that the patient can train himself to adjust his relaxation or tension, It monitors the various physiological activities that are under the control of the autonomic nervous system such as blood pressure, electrocardiogram, skin temperature, skin conduction, respiratory muscle tension, self-monitoring the change state, It says.

A variety of methods for reducing stress using biofeedback have been developed. The prior art (Korean Patent Registration No. 10-1224346) discloses a biofeedback system that uses biofeedback to reduce stress and obtain regular respiration, Feedback technology.

The conventional stress reduction method using biofeedback including the prior art has a problem in that the user can manifest the effect by checking and controlling the stress index by himself or herself, which is inevitably affected by the surrounding environment or the situation.

Further, in order to overcome the above-mentioned problem, the conventional biofeedback device provides a photograph, an image, or an image to a user, but there is a problem that biofeedback is not performed effectively to relieve tension and reduce stress do.

Referring to FIG. 1, a method for reducing a user's stress using a virtual reality and a biofeedback according to an embodiment of the present invention includes a method of reducing stress on a user of the virtual reality apparatus 100, (S100) of measuring related biometric information as reference data, measuring (S200) the change of the biometric information due to stress of the user as comparison data (S200), and comparing the analyzed data with the virtual reality device A step S300 of providing a relaxation image for reducing stress to a user and a step S400 of providing a user with stress feedback by measuring a user's stress index in real time and reducing the stress.

The bio-information related to stress according to an embodiment of the present invention may include at least one of brain waves, heart rate, heart beat variability, muscle tone, skin conductivity, respiration rate, blood volume pulse (BVP) and body temperature. In this case, the parameters for measuring the heart beat variability in the biometric information can be divided into the time domain and the frequency domain, and detailed parameters of each domain can be confirmed by referring to Table 1 below.

[Table 1]

The stress index according to an exemplary embodiment of the present invention may include at least one of a heart rate change, a respiration rate change, or a tension change of a user. That is, at least one of a change in heart rate, a change in respiratory rate, or a change in a degree of tension as a stress index can be grasped and the voice feedback can be provided based on the measurement and change of the biometric information.

According to an embodiment of the present invention, the voice feedback may be provided when the user's stress index is measured in real time and the stress index is increased beyond a predetermined ratio. For example, if at least one of the user's heart rate, breathing rate, or tension is measured in real time and if it is determined that at least one of the user's heart rate, breathing rate, or tension is increased by 15% or more, &Quot;, " breathing is accelerating ", or " tension is increasing ", can be provided to the user through the virtual reality apparatus 100. In addition, the user may be provided with spoken feedback on the physical condition of the user, such as " the body is comforting overall " or " the body is not yet sufficiently relaxed " With this spoken feedback, the user can effectively control the stress.

In addition, according to an embodiment of the present invention, the voice feedback is stored in a pre-recorded form and is provided through the voice feedback unit 40 or an external person other than the user checks the stress index in real time and provides voice feedback can do. For example, spoken feedback can be provided through the spoken feedback provider 40 in accordance with a stress indicator measured in real time in a state where a woman or a male voice with a quiet bass is pre-recorded and stored on the system, An outsider (eg, a parent or a lover) who gives a sense of security can identify stress indicators measured in real time and provide spoken feedback through direct nurturing.

According to an embodiment of the present invention, a method of reducing a user's stress using virtual reality and biofeedback includes a step S500 of measuring a change in a user's biological function by the provided relaxation image as feedback data (S500) And a step S600 in which the relaxation image is classified according to the degree of stress experienced by the user based on the data. That is, the present invention aims at providing a biofeedback tailored to a user's condition as well as a purpose of effectively reducing the stress by using the biofeedback by the user himself. Therefore, the biofilm change due to the relaxation image is measured Based on the degree of stress, relaxation images to be provided can be classified. In addition, the relaxation image can be quantified by classifying the new relaxation image according to the degree of stress based on the image classified through the above-described process.

Referring to FIG. 3, a method for reducing a user's stress using virtual reality and biofeedback according to an exemplary embodiment of the present invention includes a method of changing a state of a user before, during, and after use of the virtual reality apparatus 100 And a step S700 of estimating through a post-use questionnaire. In other words, the user state estimating unit 70, before and after the use of the virtual reality apparatus 100 and the after-use state estimating unit 70 of the virtual reality apparatus 100 may be provided to the user so that the user can evaluate and confirm the change of the physical and psychological states, , Which can be used to estimate changes in psychological and physical conditions such as depression and anxiety.

According to one embodiment of the present invention, the questionnaire for estimating changes in the above-mentioned physical and psychological state may include a screening test, PSS-10, STAI, PANAS, EQ-5D-5L, SDS and ESM. In the Kessler Psychological Distress Scale-6, there was a Mini-International Neuropsychiatric Interview (MINI) screening test. In the Kessler Psychological Distress Scale-6, stress was scored from 0 to 24 points. If the score is higher than 13 points, it is classified as experiencing severe psychological stress.

PSS-10 (Perceived Stress Scale) is a subjective index that can quantify perceived stresses over the past month. It can add 10 items, but scores 4, 5, 6 and 8 can be scored in reverse to evaluate the stress level . The State-Trait Anxiety Inventory (STAI) is a state-trait anxiety scale consisting of 20 items asking how to feel special situations at the moment and 20 items asking about the inherent innate emotional anxiety characteristics of individuals. Positive and Negative Affect Schedules (PANAS) are characterized by compressing 20 independent positive and negative emotions into 10 items, reflecting 10 positive emotions and 10 adjectives reflecting negative emotions .

The EQ-5D-5L is composed of five areas of exercise, self-management, daily activities, special / discomfort, and anxiety / depression, and each area can be divided into five levels to judge the quality of life of the user. The self-report questionnaire for measuring the degree of damage is composed of three items. Each item is divided into 11 levels from 0 to 10 points. The Experience Sampling Method (ESM) is a technique that can be continuously evaluated over several days about the annoying moments, psycho-emotional experience, and negative emotions that face daily with structured reporting techniques.
