FIELD OF THE INVENTION [0001] The present invention relates to a system and a method for a patient-

The present invention relates to a system and method for treating addiction, and more particularly, to a system and a method for treating a patient-tailored addiction using a biological signal.

Cognitive behavioral therapy is a technique that treats the social behavioral dysfunction as a result of repeatedly performing cognitive and behavioral corrections on the premise that it is caused by misconceptions about an event or situation.

Conventional cognitive behavioral therapy is a method performed by a user according to fixed scenarios determined according to the treatment purpose presented by the medical staff. However, this approach has realistic limitations in continuously communicating the status of continuously changing users to clinical or psychological counselors. In addition, there is a limitation in objectifying the comprehensive state of the user's perception (concentration, executive power, etc.), emotion (anger, depression, etc.) and degree of cravings.

Hereinafter, the structure and characteristics of the present invention will be described with reference to examples, but the present invention is not limited to these examples.

1 is a block diagram of a patient-specific addiction treatment system 1000 based on bio-signals in accordance with an embodiment of the present invention. 1, a patient-customized addiction treatment system 1000 based on a bio-signal may include a sensor 100, a state determination unit 200, a cognitive behavior therapy image determination unit 300, and an image providing unit 400 have.

The sensor 100 may measure a biological signal from a user. The sensor 100 may include at least one of an electroencephalogram (EEG) sensor, a photoplethysmographic (PPG) sensor, a galvanic skin reflex (GSR) sensor, a respiration sensor, and an electromyography (EMG) . Therefore, the bio-signal described above may include at least one of EEG, pulse wave, skin conductivity, respiration, and rhythm. The sensor 100 according to an embodiment of the present invention can measure a user's central signal or an autonomic nervous system biological signal. The present invention is characterized in that the bio signal of the central signal (EEG) or the autonomic nervous system (GSR, PPG, respiration) is used as described above.

Also, in one embodiment, a skin conductivity sensor or an EMG sensor attached to a user for bio-signal measurement of a user may be attached to any part of the user's body.

The state determination unit 200 can determine the user state based on the bio-signal measured by the sensor 100. [ The user state may include a pre-classified category, such as a conventional clinical or psychological counselor, used to determine a user's psychological state. For example, the user state may include at least one of a cognitive state, an emotional state, and an aspiring state. Here, the recognition state may include a state relating to concentration, enforcement, etc., and the emotion state may include states such as anger, depression, and sadness, and the desire state may include desire.

2 shows the relationship between the user's state 20 and the bio-signal 10 measured by the sensor 100. Fig. The state determination unit 200 may determine the user state 21-23 based on at least one of the bio-signals 11-14 measured by the sensor 100. [

Referring to FIG. 2, in one example, the state determination unit 200 may determine the perceived state 21 of the user by combining the EEG signal 11 and the PPG signal 12. The connection relationship (arrow) between the bio-signal 11-14 and the user state 21-23 represented in FIG. 2 is exemplary and further a bio-signal not shown may be used to determine a specific user state. For example, the state determination unit 200 may further use the EEG signal in addition to the GSR and the respiration signal to determine the craving state.

In one embodiment, the state determination unit 200 can determine the user state based on the measured bio-signal while the first cognitive behavior therapy image is reproduced. The first cognitive behavioral therapy image may be any image provided to analyze the user's psychology. For example, in order to treat a user who is a PC game addict, the first cognitive-behavioral therapy image includes "a situation in which a PC is seen in a room", "a situation in which a PC is turned on and a game is executed in a room" Quot; and "connected state ". Here, the cognitive behavior therapy image may include a static image or a dynamic image, and may also include sound information.

In the above example, when the sensor measures the user's biomedical signal in the "situation in which the PC is seen in the room ", the state determination unit 200 can determine the state of the desire based on the measured biomedical signal. In one example, the state determination unit 200 may calculate the value of the user state. For example, the state determining unit 200 may calculate the degree of state as a numerical value, as long as the desire has a value of 2 or anger has a value of 6. [

Also, in one example, at least one of the cognitive, emotional, and cognitive states of the user may be determined based on the measured vital sign while the user views the first cognitive behavior therapy image. For example, a result with a cognitive state of 3 and a craving of 5 may be derived.

In one embodiment, the state determiner 200 may provide the clinician or psychologist with a specific value (such as concentration, enforcement, etc.), emotion (anger, depression, etc.), and degree of cravings. Thus, a clinician or psychologist can provide the treatment program needed for the current user condition. The treatment program may include a video or action instruction to be reproduced later.

In one embodiment of the present invention, the cognitive behavior therapy image determining unit 300 and the image providing unit 400 may provide the user with the above-described treatment program (action instruction, warning, etc.) for the next image or user.

In one embodiment, the cognitive behavior therapy image determining unit 300 can determine the cognitive behavior therapy image based on the determined user state. In another embodiment, the cognitive behavior therapy image determining unit 300 can determine the cognitive behavior therapy image to be reproduced subsequently based on the determined user state and stimulus information of the regenerated cognitive behavior therapy image.

To this end, the patient-specific addiction treatment system 1000 based on bio-signals may further include a database (not shown) storing stimulus information on the cognitive behavior therapy image and the cognitive behavior therapy image. The database may be contained within a patient-specific addiction treatment system 1000 based on a bio-signal, or may be stored in an external device. The stimulus information may include the type and degree of the stimulus.

3 is a block diagram of a cognitive behavior therapy image determining unit 300 according to an embodiment of the present invention. Referring to FIG. 3, the cognitive behavior therapy image determining unit 300 determines a type of a stimulus to be provided to the user based on the determined user state, a cognitive behavior evaluating unit 310 for determining the degree of stimulation, And a second cognitive-behavior-therapy-image determiner 320 for determining a second cognitive-behavioral therapy image having a degree of cognitive-behavioral therapy.

For example, if the user state acquired from the user who watches the first cognitive behavior therapy image is desire 2, the cognitive behavior evaluation unit 310 determines the type of stimulus to be provided to the user and determines the degree of stimulation to 1 Or 3, respectively. Here, the stimulus may be cognition, emotion, or desire corresponding to the user state. It provides a smaller stimulus when the degree of cravings is 1 and provides a greater stimulus than the degree of cravings of 3.

4 is a diagram for explaining a step of determining a second cognitive behavior therapy image, in an embodiment. Referring to FIG. 4, the horizontal axis represents time t, and alphabets and numbers displayed on the right side of each image 51-54 indicate the type and degree of the stimulus. For example, A1 indicates the degree of craving is 1, and B2 indicates the degree of anger.

Referring to FIG. 4, the stimulus information of the first cognitive behavior therapy image 51 is B1. Assuming that the user state obtained from the user viewing the first cognitive behavior therapy image 51 is B1, the cognitive behavioral therapy image determination unit 300 determines the user state B1 and the reproduced first cognitive behavioral treatment image 51 The second cognitive behavior therapy image can be determined based on the stimulation information B1. Referring to FIG. 4, the cognitive behavior therapy image determining unit 300 may determine a second cognitive behavior therapy image 54 that provides anger 2 (B2) from the second cognitive behavior therapy images 52-54. Accordingly, the user can view the second cognitive-behavior therapy image 54 having the stronger degree of anger after watching the first cognitive-behavioral treatment image 51.

In one embodiment, the state determination unit 200 can determine the second user state based on the measured biometric signal while the second cognitive behavior therapy image is reproduced. Thereafter, the cognitive behavior therapy image determining unit 300 may determine the third cognitive behavior therapy image based on the second user state. That is, according to an embodiment of the present invention, an appropriate image can be determined based on continuous image reproduction and biometric information obtained from each image, and can be provided to a user.

In one embodiment, the second cognitive behavioral therapy image may be an image that is reproduced after the first cognitive behavior therapy image, or an image that is displayed together with a portion of the first cognitive behavior therapy image. This relationship is equally applicable to the relationship between the second cognitive-behavioral therapy image and the third cognitive-behavioral therapy image.

Referring to FIG. 4, after the first cognitive behavior therapy image is reproduced, a second cognitive behavior therapy image is reproduced. Since the first and second cognitive-behavioral therapy images have different types and degrees of stimuli, the user can experience cognitive-behavioral therapy by receiving different experiences and stimuli from each image.

5 shows a state in which a second cognitive behavior therapy image is provided according to another embodiment of the present invention. In FIG. 4, the abscissa indicates time, whereas FIG. 5 shows a scene of the first cognitive behavior therapy image 51A displayed on the display. Referring to FIG. 5, the second cognitive behavior therapy image 55 is displayed overlapping with a part of the first cognitive behavior therapy image 51A.

Fig. 5 is an image showing a situation where the bus is missed, and it is assumed that it has stimulus information of anger 3. When it is determined that the user state obtained from the measured bio-signal while the user views the first cognitive behavior therapy image 51A exceeds the degree of the determined anger, the cognitive behavior therapy image determination unit 300 determines The second cognitive behavior therapy image 55 may be provided to the user as a warning message. Accordingly, the user can recognize that the current state has an excessive rage.

The video data providing unit 400 may provide the user with the determined cognitive behavior therapy image. That is, the image providing unit 400 may provide the user with the first to third cognitive behavior therapy images.

Also, in one embodiment, the image data providing unit 400 may include at least one of a flat display, a curved display, and a head-mounted display (HMD). In order to improve the immersion level of the user, the image providing unit 400 may provide the cognitive behavior therapy image in the virtual reality environment through the head-mounted display. For example, a virtual reality environment can provide a situation where a user is waiting for a bus at a stop and then misses the bus.
