Hereinafter, a detailed configuration of a spectacle device for improving concentration according to an embodiment of the present invention will be described with reference to the drawings.

The present invention is based on a shutter glass type 3D glasses (three-dimensional glasses) having a plurality of shutters corresponding respectively to the left and right eyes to alternately open and close the shutters at specific frequencies, The user can implement the eyeglass device 1 and manipulate the shutter with a low frequency (particularly, an EEG) such that the user can see the flicker, thereby inducing the EEG associated with the improvement of the concentration.

1 and 2 are a perspective view and a structural view of a spectacle device 1 for improving concentration. As shown in the figure, the spectacle device 1 for improving the concentration is composed of a main body constituting a shutter glass type eyeglass .

The body portion may include a frame portion 11 constituting the spectacle frame and a plurality of spectacle leg portions 12 coupled to both sides of the frame portion 11 so as to be rotatable.

In addition, the spectacle device 1 may include a plurality of shutter portions 20 that are configured to be openable and closable as the lens of the spectacles in the main body portion.

The plurality of shutter units 20 may include a liquid crystal material that changes the polarization direction of light according to a current or a voltage applied to the shutter unit 20. The shutter unit 20 may selectively open and close the shutter unit 20, .

The plurality of shutter units 20 may include a left shutter unit 20a corresponding to the left eye and a right shutter unit 20b corresponding to the right eye. The left shutter unit 20a and the right shutter unit 20a 20b may be coupled to the lens portion of the frame portion 11.

The frame portion 11 of the main body may be configured to include a control portion 50 for controlling the opening and closing of the shutter portion 20 and a sensor portion 30 for generating sensing information by measuring the external light amount. (30) may be formed in the frame part (11).

At this time, the controller 50 executes the overall control function of the spectacle device 1 and can perform various functions described in the present invention. In addition, the controller 50 may include a RAM, a ROM, a CPU, a GPU, and a bus, and the RAM, the ROM, the CPU, and the GPU may be connected to each other via a bus.

In addition, the frame unit 11 of the main body may be configured with a user input unit 40 for receiving user input.

In addition, the frame unit may include a power supply unit (not shown) for supplying power to a component requiring power supply among various components included in the main body unit.

According to the above-described configuration, the present invention operates to stimulate eyes that have the greatest influence on the brain waves of the user's sensory organs to improve the concentration of the user wearing the spectacle device 1 for improving the concentration, The stimulation and induction of the beta wave and the alpha wave associated with the stimulation can be performed. This will be described in detail with reference to the drawings based on the above-described configuration.

3, a frequency range corresponding to an alpha wave and a beta wave may be preset in the controller 50 to improve concentration, and the alpha and beta waves of the user may be stimulated and / Scheduling information for one or more frequency-dependent schedules belonging to the frequency range may be preset in the control unit 50 so as to induce the scheduling.

For example, the schedule information may include information that is set so that a plurality of different frequencies are varied in a predetermined order according to a preset pattern at a predetermined cycle (predetermined cycle).

Accordingly, the controller 50 varies the frequency within the frequency range according to the schedule information, and controls the plurality of shutter units 20 according to the current frequency to open / close each of the plurality of shutter units 20 .

The control unit 50 may control the plurality of shutter units 20 to synchronize with each other at a specific frequency according to the schedule information or may control the plurality of shutter units 20 at different frequencies .

That is, the control unit 50 opens and closes each of the plurality of shutter units 20 according to the frequency to alternate transmission and blocking of natural light through the shutter unit 20, Can be visually confirmed.

At this time, it may be more effective to improve the concentration when flicker of different patterns occurs in the right eye and left eye, rather than providing flicker stimulation of the same pattern (or synchronized pattern) in the right eye and left eye.

Accordingly, the controller 50 can operate in either a synchronous mode or an asynchronous mode, which is preset based on user input through the user input unit 40. This will be described in detail with reference to FIG.

4 (a), when the control unit 50 operates in the synchronous mode based on the user input, the controller 50 controls the plurality of shutter units 20 according to a specific frequency selected according to the schedule information, It is possible to control opening and closing with the same flicker pattern.

As shown in FIG. 4B, the controller 50 may operate in an asynchronous mode based on the user input to maximize improvement in concentration through the flicker stimulus. In the asynchronous mode, When controlling (opening and closing) the plurality of shutter portions 20 according to the specific frequency, any one of the plurality of shutter portions 20 can be controlled according to a frequency having a phase opposite to the phase of the specific frequency.

That is, the control unit 50 adjusts the phase of the specific frequency so that the plurality of shutter units 20 have different flicker patterns so that any one of the plurality of shutter units 20 is in phase By controlling according to the frequency, it is possible to perform opening / closing control so that the plurality of shutter portions 20 have different flicker patterns.

When the control unit 50 controls the plurality of shutter units 20 at a specific frequency, the control unit 50 controls the opening and closing of any one of the plurality of shutter units 20 at a frequency opposite to the specific frequency, When the transmittance of the right eye shutter portion 20b is high, the transmittance of the left eye shutter portion 20a is low. When the transmittance of the right eye shutter portion 20b is low, the left eye shutter portion 20a ). Thus, it is possible to induce EEG with higher efficiency than stimulation with a mutually synchronized pattern in the left eye and right eye, as well as to provide a high concentration effect.

As described above, the user wearing the spectacle apparatus 1 is stimulated by the opening and closing operation of the shutter unit 20 in accordance with the frequency-based control of the control unit 50, so that at least one of the alpha wave and the beta wave Can be activated (induced), which can improve concentration.

In addition, the present invention provides different flicker in the left and right eyes of a user by differentiating the frequency used for the opening / closing control of one of the plurality of shutter portions 20 and the frequency used for the other opening / closing control, It is possible not only to increase the efficiency of inducing EEG, but also to improve the concentration of users.

Meanwhile, in the above-described configuration, the reference duty ratio of the frequency is preset to the controller 50, and the controller 50 controls the shutter unit 20 at a frequency corresponding to the reference duty ratio The brightness of the light transmitted through the shutter unit 20 is applied to the eye of the user at a reference brightness corresponding to a predetermined reference stimulus intensity to obtain a reference brightness corresponding to the most suitable stimulus intensity Can be adjusted.

However, when the amount of ambient light is high according to the change of the ambient light amount, the intensity of the stimulus transmitted to the eye may be higher than necessary, and when the amount of ambient light is low, the stimulus intensity is low, And thus it may be difficult to generate a desired brain wave if the light of appropriate brightness according to the amount of ambient light is not transmitted to the eye.

5, the controller 50 may receive the sensing information from the sensing unit, determine the amount of ambient light based on the sensing information received from the sensing unit, The transmittance of the shutter unit 20 can be adjusted by adjusting the duty cycle of the frequency according to a preset duty ratio corresponding to the intensity of the stimulus corresponding to the intensity of the stimulus corresponding to the intensity of the stimulus, The brightness of the light or the brightness of the shutter unit 20 can be adjusted according to the ambient light amount.

At this time, the controller 50 may store setting information for a duty ratio corresponding to the ambient light amount, and the controller 50 may select a duty ratio corresponding to the ambient light amount according to the setting information, The duty cycle of the frequency may be adjusted according to the selected duty ratio, and the shutter unit 20 may be controlled according to the duty cycle of the duty cycle.

Here, the setting information may include information on duty ratios of different light amount ranges, and the controller 50 may select a duty ratio corresponding to the light amount range to which the light amount corresponding to the sensing information belongs, The duty cycle of the frequency may be adjusted.

5 (a), the control unit 50 controls the duty cycle of the frequency according to the first duty ratio preset to the setting information corresponding to the amount of ambient light when the amount of ambient light is high, for example, And controls the shutter unit 20 based on a frequency whose duty cycle is adjusted (changed) in accordance with the first duty ratio, thereby controlling the transmittance of the shutter unit 20 to the shutter unit 20 according to the reference duty ratio. Lt; / RTI > transmittance.

The controller 50 controls the exposure time of the light through the shutter unit 20 based on the first duty ratio that is lower than the reference duty ratio when the amount of ambient light of brightness corresponding to the reference duty ratio is detected, The brightness of the light passing through the shutter unit 20 (or the brightness of the shutter unit 20) can be reduced by decreasing the exposure time of the light according to the duty ratio, So that the user's eyes can be stimulated.

5 (b), when the brightness of the ambient light is low, the controller 50 controls the brightness of the frequency according to the second duty ratio preset to the setting information, And controls the shutter unit 20 based on a frequency whose duty cycle is adjusted (changed) according to a second duty ratio to adjust the transmittance of the shutter unit 20 to the shutter speed Can be adjusted to be higher than the transmittance of the light emitting portion (20).

The control unit 50 determines the exposure time of the light through the shutter unit 20 based on the second duty ratio that is higher than the reference duty ratio when the ambient light amount lower than the brightness corresponding to the reference duty ratio is detected. It is possible to increase the brightness of the light passing through the shutter unit 20 (or the brightness of the shutter unit 20) by increasing the exposure time of the light according to the reference duty ratio, It is possible to stimulate the user's eyes with brightness.

In the above-described configuration, the controller 50 can adjust the duty cycle through PWM (Pulse Width Modulation) control, adjusts the transmittance of the shutter unit 20 by adjusting the duty cycle, The intensity of the stimulus can be adjusted.

At this time, the controller 50 may control the duty cycle of the PWM system to adjust the transmittance of the shutter unit 20 so that the transmittance change has a specific pattern. For example, The shutter unit 20 can be controlled so as to have a pattern such that the shutter unit 20 becomes gradually brighter or darker by adjusting the cycle.

As described above, according to the present invention, the spectacle device 1 for improving the focusing ability controls the shutter unit 20 according to the amount of ambient light to adjust the brightness of light applied to the user's eyes, Stimulation of the user's eyes by the stimulation intensity of the stimulus, thereby enhancing the accuracy and efficiency of the induction of brain waves for improving the concentration, as well as minimizing the user's rejection through the binocular stimulation based on natural light.

On the other hand, in the above-described configuration, when the illumination is present in the environment using the spectacle device 1 and the flicker frequency (lighting frequency) of the illumination and the frequency for controlling the plurality of shutter portions 20 are not integral multiples The blinking occurs at a frequency different from the intended frequency through the control of the plurality of shutter units 20 due to the beat phenomenon, so that the desired EEG induction is not properly performed and inconvenience may occur in the use process.

Therefore, the controller 50 controls the user to input the user's input through the user input unit 40 so as to prevent the beating phenomenon from occurring, And a plurality of shutter portions 20 can be controlled to open and close at the selected frequency.

At this time, all the frequencies included in the schedule information may be set to have an integral multiple of the flicker frequency of the illumination.

For example, when the spectacle device 1 is used in a country using a 60 Hz power source, the lighting flicker frequency (ambient lighting frequency) of 60 Hz, 40 Hz, 30 Hz, 24 Hz, 20 Hz, 17.14286 Hz, (50 Hz, 33.333 Hz, 25 Hz, 20 Hz, 16.6666 Hz, etc.) having integer multiples when using the spectacle apparatus (1) in a country using a 50 Hz power source And may be set in the controller 50.

The control unit 50 may generate and store the schedule information in at least one frequency having an integer multiple of an ambient illumination frequency set according to a commercial power source frequency based on a user input through the user input unit 40, One or more frequencies having an integer multiple of the peripheral illumination frequency may be set in the schedule information.

At this time, the schedule information is set to an integer multiple of a sequence (or a cycle) that constitutes a schedule according to the schedule information for setting the frequency related to the opening / closing control of the shutter unit 20 corresponding to the peripheral illumination frequency And the control unit 50 calculates the frequency per sequence by applying an integer multiple of the schedule information to the peripheral illumination frequency for each sequence according to the schedule information when the ambient illumination frequency is set based on the user input, The schedule information may be updated by storing the schedule information corresponding to the peripheral illumination frequency and may be stored in the schedule information or may be set to the schedule information.

That is, the control unit 50 may automatically generate and store schedule information corresponding to the peripheral illumination frequency in the setting of the peripheral illumination frequency based on the user input, the schedule information having at least one frequency relationship with the peripheral illumination frequency according to the user input Setting).

For example, when an integer multiple of 1 is previously set in the first sequence constituting the schedule according to the schedule information, an integer multiple of 2 is preset in the second sequence, and when 50 Hz is set according to the user input, The control unit 50 calculates 50 Hz by applying an integral multiple of the first sequence to the ambient illumination frequency in correspondence with the first sequence, sets the schedule information in the schedule information, and sets an integer multiple of the second sequence corresponding to the second sequence It is possible to update the schedule information by generating 25 Hz by calculating the frequency of 25 Hz according to the peripheral illumination frequency, or to generate new schedule information in which the frequency is set according to the sequence, and to store the schedule information in which the frequency for each sequence is set.

Accordingly, the controller 50 can control the opening / closing of the plurality of shutter units 20 at a frequency having an integer multiple of the ambient lighting frequency according to the schedule information.

At this time, the integer multiples of the sequences set in the schedule information may be set to different integer times from each other.

Meanwhile, the eyeglass device 1 for improving concentration of attention according to the embodiment of the present invention not only provides a function of inducing brain waves for guiding a user's sleeping, but also provides a function of improving the user's amblyopia (amblyopia correction function) Function to provide versatility, which will be described in detail below with reference to the drawings.

6, the control unit 50 operates in a first mode related to the concentration-enhancing effect through stimulation of alpha waves and beta waves, as well as a second mode related to sleep induction through stimulation of delta waves and seta waves And can support sleep induction of the user.

For example, the control unit 50 may include a first mode for improving concentration and second mode related mode information for inducing sleep, and may include information on mode information based on a user input through the user input unit 40 Can be selected from among a plurality of modes corresponding to the plurality of modes.

In addition, the controller 50 operates as described above in the case where the mode selected according to the user's input is the concentration-related improvement first mode, and when the selected mode is the second mode related to the sleep induction, The first frequency range corresponding to the alpha waves and the beta waves for improving the concentration can be changed to the second frequency range corresponding to the delta waves and the set waves and can operate in the same manner as the operation configuration for improving the concentration.

In addition, the schedule information may include schedule-related first information corresponding to the alpha and beta waves for improving the concentration, second information related to the delta waves and the schedule, and the controller 50 may select When the mode is the first mode, the shutter unit 20 can be controlled while varying the frequency within the first frequency range based on the schedule according to the first information, and when the selected mode is the second mode, The controller 20 controls the shutter unit 20 while varying the frequency within the second frequency range based on the schedule according to the second information, thereby stimulating the user's optic nerve and inducing the user's sleeping-related electroencephalogram.

In this case, the first frequency range may be 8 to 50 Hz including the low band of the gamma wave in consideration of the frequency range of the alpha wave (8 to 13 Hz) and the beta wave (13 to 30 Hz) The frequency range may be 0.5 to 8 Hz, including the delta wave (0.5 to 4 Hz) and the frequency range of the setter (4 to 8 Hz).

In addition, as described above, the control unit 50 may select the second mode for the sleep-inducing mode in the second frequency range in the same manner as the operation configuration in the first mode for improving the concentration, The frequency can be adjusted according to the amount of ambient light to stimulate the user's eyes by providing light of suitable brightness to induce sleeping-related EEG.

As shown in FIG. 7, the controller 50 may operate in a third mode for improving ambience according to user input through the user input unit 40 among a plurality of modes according to the mode information.

In addition, the controller 50 selects the first shutter unit 20a corresponding to the eyes of the plurality of shutter units 20, which are not amblyopic, based on the user's input during the operation in the third mode, And controls the duty cycle of a preset frequency corresponding to the third mode according to a duty ratio selected in accordance with the third mode or a preset duty ratio corresponding to the third mode, and controls the first shutter unit 20a to correspond to the third mode And the brightness of the light passing through (passing) the first shutter unit 20a can be adjusted by opening and closing the duty cycle according to the adjusted frequency.

The controller 50 may also be configured to open the second shutter unit 20b corresponding to the observer's eyes so that the brightness of the light transmitted through the second shutter unit 20b is transmitted through the first shutter unit 20a It can be controlled to be brighter than the brightness of light.

Alternatively, the mode information may include frequency-related information corresponding to the third duty ratio corresponding to the third mode, the fourth duty ratio corresponding to the eye having an ambiguous eye, The control unit 50 generates a first frequency by adjusting a preset frequency corresponding to the third mode to have a duty cycle according to the third duty ratio based on the mode information, And a second frequency can be generated by adjusting a preset frequency to have a duty cycle according to the fourth duty ratio.

Accordingly, the control unit 50 opens and closes the first shutter unit 20a corresponding to the non-amblyopia selected according to the user's input among the plurality of shutter units 20 according to the first frequency, The second shutter portion 20b corresponding to the eye is opened or closed according to the second frequency so that the brightness of the light transmitted through the first shutter portion 20a and the brightness of the light passing through the second shutter portion 20b Brightness can be adjusted differently.

At this time, the first frequency and the second frequency may be different from each other.

That is, the controller 50 generates a plurality of different frequencies corresponding to the third mode, and controls the transmittance of the first shutter unit 20a and the transmittance of the second shutter unit 20b to be different from each other, The first and second shutter portions 20a and 20b can be controlled based on a plurality of different frequencies.

Accordingly, the controller 50 may be configured to provide strong stimulation by external light rather than eyes that are not amblyopic in the eye of the user, or to provide strong stimulation by the external light in the same brightness between the eyes, So that the amblyopic eye can be improved.

That is, the control unit 50 can independently control each of the plurality of shutter units 20, thereby adjusting the brightness of light according to the degree of amblyopia of the eyes of the user, .

In addition, the controller 50 may operate in a fourth mode for protecting a user's eyesight according to user input among a plurality of modes according to the mode information.

At this time, when the controller 50 operates in the fourth mode, the controller 50 sets a duty cycle corresponding to the fourth mode so as to have a predetermined duty ratio or a duty cycle according to a user input, And the plurality of shutter portions 20 can be simultaneously opened and closed according to a frequency corresponding to the fourth mode and having a variable duty cycle, thereby controlling the transmittance and lightness of the plurality of shutter portions 20, Can be adjusted.

Accordingly, the control unit 50 can control the degree of light transmission according to the transmittance of the plurality of shutter units 20 to protect the user's visual acuity.

The control unit 50 can reduce a bad EEG by corresponding to a use purpose corresponding to a mode selected by a user among a plurality of use applications respectively corresponding to the plurality of modes according to a user's EEG state, It can operate on the basis of neurofeedback techniques.

The controller 50 may be configured to measure the user's brain waves to generate state information on the state of the user's brain wave and provide the state information to the controller 50. In addition, May determine the current state of the user's brain wave according to the state information received from the brain wave measuring unit (60).
