The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the term " comprising " or " consisting of ", or the like, refers to the presence of a feature, a number, a step, an operation, an element, a component, But do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms such as those defined in commonly used dictionaries are to be interpreted as having a meaning consistent with the contextual meaning of the related art and are to be interpreted as either ideal or overly formal in the sense of the present application Do not.

It is to be understood that the first to second aspects described in the present specification are merely referred to in order to distinguish between different components and are not limited to the order in which they are manufactured, It may not match.

In explaining the present invention, it is first revealed that the 'size' of a pupil, which will be described later, means a diameter.

In addition, according to the published research data, it can be seen that the size of the pupil increases in the stimulation of interest or interest. However, since the purpose of the present system (D) is to be used for psychotherapy, It is based on measuring only the degree of negative attitude of the patient (subject) and thus not considering the change in pupil size for positive stimulation (interest, interest).

The present invention relates to a psychological state diagnosis system (D) for measuring a change in a pupil size of a subject for use in psychotherapy, analyzing a current psychological state according to the change value, and diagnosing a psychological state based on the analyzed psychological state.

The pupil is an empty space in the center of the iris, and the amount of light entering the eye depends on the size of the pupil. The size of the pupil is controlled autonomously by contraction and relaxation of the pupillary sphincter and syngeneic muscle, and it is known that the size of the pupil changes reflexively according to the amount of light entering the eye.

However, the size of the pupil does not simply change due to the surrounding brightness. As described in many medical papers and journals, changes in human psychological states affect the pupil size.

For example, given the fear stimulus, the size of the pupil becomes larger, as described in 'Understanding the intention through the user's gaze feature and the selective attention model based on understanding brain function information' (Prof. Lee Min- ho, Kyungpook National University, 2011. Seminar data) When the comfortable stimulus is given, the size of the pupil changes according to the magnitude of the stimulus (change) and the type of stimulus (magnification or reduction), as the size of the pupil decreases.

In order to utilize the change in pupil size according to the psychological state, the pupil size is measured in a normal state, the pupil size in a state in which a psychological state is to be determined is measured, the two values are compared to calculate a change amount, And to analyze the psychological state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of the present invention.

As shown in Fig. 1, the system D comprises a measurement module 1, a processing module 2, a storage module 3 and an analysis module 4.

The modules may be provided in a single housing, or may be provided in a plurality of housings, and each of the modules may be formed of a single unit.

First, the measurement module 1 captures the pupil of the subject and acquires the image. Generally, the measurement module 1 may correspond to the camera.

Next, the processing module 2 is configured to derive the pupil size (diameter) value of the subject by processing the pupil image acquired by the measurement module 1. The processing module 2 can be implemented by a central processing unit (CPU) Language and can perform the functions described above.

Next, the storage module 3 stores the psychological state analysis information corresponding to each level according to the pupil size change. The storage module 3 can be implemented by a memory, and the psychological state analysis information is previously stored in the memory . More specific psychological state analysis information will be described later.

Next, the analysis module 4 may be implemented by a central processing unit (CPU), such as the processing module 2, and may be coded in a programming language to perform the functions.

In particular, the analysis module 4 constituting the core of the present invention includes a calculation unit 41, an allocation unit 43 and a determination unit 45 as shown in FIG.

The calculation unit 41 is configured to calculate the change value of the pupil size by comparing the reference pupil size value of the subject measured in the normal state with the pupil size value derived from the processing module 2. Here, Means a relaxed state without stimulation and is preferably measured before starting the psychological diagnosis.

The assigning unit 43 assigns a level according to the change value of the pupil size calculated by the calculating unit 41. The level to be assigned can be matched with the psychological state analysis information stored in the storage module 3 It is obvious that the level interval should be set so that

The determination unit 45 is configured to determine the psychological state of the subject by comparing the level assigned by the assignment unit 43 with the psychological state analysis information stored in the storage module 3, The current psychological state of the subject can be derived by determining which level section the psychological state corresponds to.

2 illustrates an example of psychological state analysis information utilized in the present invention. Such psychological state analysis information is derived by repeated experiments and research as described above.

As shown in Fig. 2, the assigning unit 43 is set to Level 1 when the pupil diameter is less than -3.0 mm and less than -2.0 mm, and to Level 2 when the pupil diameter is less than -2.0 mm and less than -1.0 mm. Level 4 is assigned when level is less than +1.0 mm and not more than 1.0 mm. Level 4 is assigned when level is less than + 1.0 mm or more + 1.5 mm. Level 5 is assigned when level is less than + 1.5 mm or more + 2.0 mm.

The psychological state analysis information stored in the storage module 3 is composed of [Level 1 = very positive], [Level 2 = Positive], [Level 3 = Normal], [Level 4 = Negative], and [Level 5 = .

Previous studies have shown that when performing difficult tasks, the size of the subject's pupil increases with difficulty. (Source: S. Ahern & JB eatty, Pupillary responses during information processing vary with scholastic aptitude test scores. Science, 1979))

In addition, it can be seen that the size of the pupil of the subject becomes larger when viewing a horror or a disgusting picture. (Seminar data on "understanding of brain function information and understanding of intention through selective attention model". . 2011.)

Based on these data, it can be seen that the size of the pupil increases when a person reacts negatively, and the size of the pupil decreases when a positive response occurs.

The setting of the level interval of the assigning unit 43 is derived by an average value obtained by repeated experiments and the psychological state analysis information stored in the storage module 3 is also derived based on the questionnaire preparation of the subject.

The level 0 of the level section of the assigning section 43 corresponds to a change in the size of an abnormal pupil that does not correspond to any level section. In the case of level 0, the measurer recognizes the value as unreliable and re- something to do.

On the other hand, in using the system D, in order to turn on / off a power by using a remote controller (a remote controller) or perform a data processing operation in a power off state, It is necessary to generate operating power so that it can operate. If it does not supply the operating power through its own circuit configuration, such a power supply must be made using the battery. The system (D) further comprises operating power supply means for supplying such operating power.

Hereinafter, the implementation of the power supply means 5, which is one embodiment of the present invention, will be described with reference to the accompanying drawings (FIG. 3).

Particularly, the power supply unit 51 operates the external power supply circuit 511 during the ON operation of the switch unit 52 to generate the power supply using the external power supply s. In the off operation of the switch unit 52, The power supply circuit 513 is operated to generate an internal power source from the external power source s, and the power source is generated by using the internal power source.

Here, the power supply is a power generated by the external power supply (s) or the internal power supply and applied for operation of each configuration.

More specifically, the external power supply circuit 511 of the power supply unit 51 includes a capacitor C1 and a third bridge diode BD3 connected in series to the external power source s, a charge capacitor C5 connected in parallel thereto, .

The internal power supply circuit 513 includes a first bridge diode BD1 connected in parallel to the external power supply s, a transformer T1 and a second bridge diode BD2 connected in parallel thereto, And a capacitor C5.

In the above description, the charging capacitor C5 has the same configuration and is configured to be charged by the current rectified by the DC by the first and second bridge diodes BD1 and BD2, and stores and outputs the supplied power.

The output terminals of the external power supply circuit 511 and the internal power supply circuit 513 are connected to each other. That is, the output terminal of the first bridge diode BD1 and the output terminal of the second bridge diode BD2 are connected to each other.

 The switch unit 52 is configured to select the operation of the external power supply circuit 511 or the internal power supply circuit 513. The switch unit 52 includes a triac Q1 (Triac) connected in series with the third bridge diode BD3, Lt; / RTI > The ON / OFF determination signal of the switch unit 52 can be received from outside or inside the apparatus. The signal generating circuit of the switch unit 52 is not shown in the drawings, but a person skilled in the art If you are a person, you can only understand and reason.

The control unit 53 includes resistors R1 and R2 and capacitors C2 and C3 connected to the third bridge diode BD3 or the transformer T1 that are connected in parallel to each other at one end and connected to the ground at the other end . The control unit 53 may be connected to both the transformer T1 and the third bridge diode BD1.

3, the external power supply circuit 511 is connected to the first bridge diode BD1 at one end and to the ground at the other end, and a drop resistor R3. It is possible to prevent the first bridge diode BD1 from being destroyed by the high voltage of the external power source s due to the dropout resistor R3.

The power supply unit 51 further includes a stabilization circuit provided at the output terminals of the first bridge diode BD1 and the second bridge diode BD2. The stabilization circuit includes a first bridge diode BD1 and a second bridge diode BD2, A capacitor C4 connected in parallel to the zener diode ZD1 and a capacitor C4 connected in parallel to the output terminal of the inductor L1 connected to the charge capacitor C5 and the zener diode ZD1, .

3, the circuit operation of the power supply unit 5 will be briefly described. First, when a switch-on signal is inputted to the switch unit 52 (supply of the external power supply s is stopped) (The external power supply s is supplied), the switch unit 52 is turned off and the third bridge diode BD3-triac Q1 is short-circuited 3 bridge diode (BD3) -triac (Q1) 'are mutually opened. Therefore, as described above, the power supply unit 51 provides the power supply in two cases when the switch unit 52 is on and off.

In this case, the triac Q1 is short-circuited and a current flows through the third bridge diode BD3-triac Q1 ', so that a voltage drop . The voltage across the third bridge diode BD3 is transformed by the transformer T1 and rectified to the direct current through the second bridge diode BD2 and then charged into the charge capacitor C5.

Thus, when the supply of external power supply s is interrupted, the generation of the internal voltage utilizes the voltage drop across the third bridge diode BD3, the role of the original bridge diode being for rectification (the first and second bridges (BD1) (BD2)), the voltage drop can be induced by shorting two non-adjacent rectifying terminals of the bridge diode (the bridge diode consists of four rectifying terminals connected in circulation). The generation of such internal power supply has the same effects as those of the bridge circuit using four separate diodes, but also has the effects of reducing the number of parts, reducing the size of the mounting, reducing the cost, and reducing the probability of occurrence of failure.

Next, the operation of the circuit when the switch unit 52 is turned off will be described. The triac Q1 is opened and the transformer T1, the resistor R1, and the capacitor C2, which are the primary side of the transformer T1, (C1) -the first bridge diode (BD1) -drive resistance (R3) 'due to the impedance difference between the line' C1 'and the line' C1 '- the first bridge diode (R3) 'line. Therefore, the AC current from the external power source s flows to the first bridge diode BD1 through the capacitor C1, and is rectified by the first bridge diode BD1 to be charged to the charge capacitor C5.

The Zener diode ZD1 connected in parallel to the output terminals of the first bridge diode BD1 and the second bridge diode BD2 which are stabilizing circuits prevents the overvoltage and the inductor L1 and the capacitor C4 are connected in series, The noise component included in the signal is removed.

The delay circuit 553 is connected to the output terminal of the operational amplifier OP1 of the detection circuit 551 and includes a reverse diode D3 connected in parallel with each other and a resistor R11 and a capacitor C10. Since the noise is not generated continuously but is intermittently generated, if there is no delay circuit 553, the relay circuit 555 repeatedly turns on / off quickly, The delay circuit 553 does not turn off the relay circuit 555 for a certain period of time after the relay circuit 555 has been operated, Lt; / RTI >
