Description

[Technical field]

[0001] The present invention relates to a treatment light control system, a treatment light control method, and a treatment light control program. [Background technology]

[0002] It is known that continuous daily light therapy can prevent diseases related to brain activity, such as Alzheimer's disease and seasonal affective disorder. Patent Document 1 discloses a glasses-type treatment light irradiating device that prevents brain diseases through such phototherapy. In this treatment light irradiation device, an LED is placed close to the user's eyes and the LED emits treatment light that flashes at a predetermined frequency, providing the user with visual stimulation that helps prevent brain diseases.

[0003] [Patent Document 1] Special Publication No. 2020-501853 Summary of the Invention [Problem to be solved by the invention]

[0004] However, while the treatment light irradiation device described in Patent Document 1 can reliably perform treatment by irradiating light from a position close to the eye, the user may feel strong discomfort because the light is irradiated from a device fixed to the face at close range. In addition, in general, during the prevention stage, patients are living the same lifestyle as healthy people and do not feel any significant harm from the disease being prevented. For this reason, the stress caused by the preventive treatment may be greater than the anxiety of developing the disease in the future, and the preventive treatment may be discontinued.

[0005] In other words, with conventional treatment light irradiation devices, there was a trade-off between therapeutic effectiveness and ease of continued use by users, and there was a demand for the development of a system that had high therapeutic effectiveness and was easy for users to use on a continuous basis.

[0006] The present invention is characterized by providing a treatment light control system that has a high therapeutic effect and is easy for users to use continuously. [Means for solving the problem]

[0007] One aspect of the present invention is a treatment light control system comprising a light source that emits flashing light, a controller that controls the flashing frequency of the light source so that it falls within a predetermined frequency band, and a particle group emission means that emits particle groups into a spatial region into which the light source emits light. Effect of the Invention

[0008] According to the treatment light control system of the present invention, it is possible to realize both a high therapeutic effect and continuous ease of use for the user. [Brief description of the drawings]

[0010] First Embodiment Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In the drawings for explaining the embodiments, the same components are generally designated by the same reference numerals, and repeated explanations thereof will be omitted. Fig. 1 is an external view of a treatment light control system 1 according to a first embodiment of the present invention.

[0011] (1) Overview of the First Embodiment The outline of this embodiment will be described. The treatment light control system 1 (hereinafter simply referred to as the system 1) according to this embodiment is a system having a function of outputting treatment light for performing a treatment required for a user as a light stimulus acting on the user's eye.

[0012] (1-1) Overview of System 1 configuration and usage FIG. 1 is a diagram showing a configuration of a system 1 according to a representative embodiment (first embodiment). The system 1 according to the first embodiment is used to provide gamma frequency light and sound stimulation in a bathroom for the purpose of preventing, improving, and slowing the progression of dementia. Generally, in the cerebral cortex of the brain, a group of neurons fires in synchronization, generating synaptic activity, resulting in periodic neural activity (oscillation). These neural activities are classified into the theta band (4-12 Hz) and gamma band (25-100 Hz) depending on the frequency. In this explanation, gamma frequency refers to a frequency equivalent to neural activity classified into the gamma band (25-100 Hz). Gamma band neural activity is thought to be deeply involved in cognitive functions, particularly attention, memory, and judgment, and it is said that external input can have an effective effect on cognitive functions. In the following explanation, 25 Hz to 100 Hz is called the gamma band. As shown in FIG. 1, after entering the bathtub 100, the user instructs the smart speaker 61 to start treatment, and the communication function of the smart speaker 61 is used to operate surrounding devices to perform treatment using light and sound stimuli.

[0013] First, the bathroom lighting device 80 is turned off, and then the optical sensor 81 confirms that there is no optical noise that may affect the treatment. Next, the light source 11 irradiates a gamma frequency optical stimulus, an image is displayed on the liquid crystal display (image display unit 12), and mist is emitted from the mist generator 32 toward the bathtub 100.

[0014] FIG. 2 is a cross-sectional view of the system 1 shown in FIG. As shown in Fig. 2, a moving image of a landscape such as a sea of ​​clouds at sunset is particularly desirable as an image to be displayed on an LCD display. The sea of ​​clouds displayed at the bottom of the screen is integrated with the mist emitted from the mist generator 32 to create a composite visual effect, providing the user with a more realistic experience. In addition, by generating gamma frequency sound stimuli using the speaker 63 function of the smart speaker 61, treatment combining light stimuli and sound stimuli becomes possible.

[0015] FIG. 3 is a diagram showing the flow of data when the system 1 shown in FIG. 1 starts to be used. As shown in Fig. 3, when using the system 1, the user starts up a management application on the user terminal 5 as a preliminary step, and sets a protocol for treatment using light and sound stimulation (treatment protocol). The treatment protocol includes the video content to be displayed on the liquid crystal display, the amount of mist to be generated, the audio content to be used for sound stimulation, the treatment time, etc. The data for the treatment protocol is transmitted to the controller 20 in advance.

[0016] After entering the bathtub 100, the user instructs the bath pillow-type smart speaker 61 to start treatment, and the communication function of the smart speaker 61 is used to operate surrounding devices (lighting, treatment light source, LCD display, valves) to perform treatment using light stimulation. First, after turning off the lights in the bathroom, the optical sensor 81 confirms that there is no optical noise that may affect the treatment.

[0017] Next, the controller 20 for the treatment light source and liquid crystal display irradiates a gamma frequency light stimulus from the light source 11 and displays an image on the liquid crystal display. In addition, the controller 20 opens the IoT valve to start supplying hot water, and the mist generator 32 releases mist toward the bathtub 100.

[0018] Furthermore, treatment combining light and sound stimuli becomes possible by generating gamma frequency sound stimuli from the speaker 63 mounted on the smart speaker 61. Noise that impedes the effect of sound stimuli is detected by the microphone 64 of the smart speaker 61 and can be reduced by the noise canceling function of the speaker 63. A treatment log, such as the time when the light and sound stimulation treatment was performed, is transmitted from the controller 20 to the management application and stored on the cloud server 82 via an Internet line.

[0019] System 1 outputs light stimuli from a liquid crystal panel, making it possible to display a variety of images that match the differences in preferences of each user and changes in the user's preferences. It is generally known that if a person continues to be given the same visual stimuli, they will become visually accustomed to them and their attention to the object will decrease (they will become bored). On the other hand, System 1 dynamically changes the light transmission pattern by operating the liquid crystal panel, making it possible to provide images that match the diverse changes in preferences.

[0020] However, while a variety of images can be displayed using liquid crystal panels, when considering the preventive effect of light stimuli against dementia, assuming that the size of light source 11 is 1m x 0.6m (similar to a 46-inch TV), the light intensity is approximately 1200cd / m 2 A brightness of at least this level is required. A typical work display has a maximum brightness of 300cd / m 2 Considering that the brightness of the display is about the same as that of the conventional display, the user will be faced with a display image that is quite dazzling.

[0021] FIG. 4 shows the difference in positional relationship between a sea of ​​clouds at sunset as it is displayed on a display and when you actually view it. For example, a sea of ​​clouds at sunset is known as a scene that people find pleasing even when it is illuminated with strong light, as shown in Figure 4. As shown in the middle of Figure 4, strong light is illuminated from the area where the sun is visible, but the light is diffused and flickered by the cloud area in front, so it can be viewed as a pleasing scene. On the other hand, when a similar image is displayed on an LCD display, as shown in the lower part of Figure 4, the clouds are on the same plane as the display panel, so the strong light from the area showing the sun is shone directly on the user.

[0022] (1-2) Overview of the effects of System 1 Therefore, in addition to the liquid crystal display, the system 1 is equipped with a particle emission device 30 that emits particle groups such as mist. This allows the light emitted from the display to fluctuate three-dimensionally, providing the user with a pleasant visual effect similar to that of a fluctuating natural landscape. In other words, the user can prevent dementia while having fun without feeling any discomfort.

[0023] In this way, the present invention solves the problems of boredom and discomfort caused by light stimulation through the diverse images provided by the video output device and the three-dimensional fluctuation of light provided by the mist (group of fine particles), allowing users to continue treatment with light stimulation without stress and preventing dementia.

[0024] In addition to Alzheimer's disease, the system 1 can also be used to treat other neurological and psychiatric disorders, such as Parkinson's disease and depression. For example, it has been shown that gamma frequency stimulation of the skin is effective in improving the motor symptoms of Parkinson's disease. The system 1 can also stimulate the skin of the user using the skin stimulation device 70, which will be described later, so that the use of the system 1 may further enhance the therapeutic effect.

[0025] (2) System 1 Configuration A description will now be given of the configuration of the system 1. Fig. 5 is a block diagram showing the configuration of the system 1 shown in Fig. 1.

[0026] 5, the system 1 includes a light stimulation device 10, a controller 20, a fine particle group emission device 30, a user analysis device 40, a voice recognition device 50, a sound stimulation device 60, and a skin stimulation device 70. The system 1 is communicatively connected to a lighting device 80, a light sensor 81, and a cloud server 82 by wire or wirelessly. The system 1 is also communicatively connected to a user terminal 5 used by a user by wirelessly.

[0027] (2-1) Configuration of the optical stimulation device 10 The light stimulation device 10 is an image output device including a light source 11 and an image display unit 12 . The light source 11 of the light stimulation device 10 mainly emits blinking light forward. A panel-shaped LED light source can be used as the light source 11. FIG. 6 is a diagram showing the panel-shaped LED light source of the light stimulation device 10. As shown in Fig. 6, the panel-shaped LED light source has a structure in which many LEDs are arranged in a grid pattern vertically and horizontally. The panel-shaped LED light source mainly emits light forward (toward the user's position). That is, the light source 11 occupies a certain area perpendicular to the main emission direction.

[0028] To be able to emit a strong light stimulus, it is desirable to adopt an LED array in which LEDs are arranged in a grid pattern across the entire panel as the light source 11. By using an LED array as the light source 11, there is less loss of light compared to a structure in which light is emitted via a scattering plate and a reflector, which will be described later, and high-brightness LEDs can be arranged at a high density.

[0029] As shown in Fig. 1, the image display unit 12 of the light stimulation device 10 is disposed in front of the light source 11, and displays a predetermined image on the image surface by transmitting the light irradiated from the light source 11. A variety of images that match the diverse preferences of users are displayed on the image display unit 12, and the mist creates a three-dimensional fluctuation of light. These means allow the user to receive the light stimulation comfortably while enjoying the realistic changes.

[0030] The liquid crystal display used as the image display unit 12 controls the pattern through which light is transmitted. Liquid crystal display structures are broadly divided into two types, a passive type and an active type, and it is preferable to use an active type liquid crystal display that has excellent responsiveness.

[0031] In an active-type liquid crystal panel, each pixel is equipped with an active element (transistor). Each transistor is connected to an X electrode that switches the transistor and a Y electrode that lights up the pixels in each row, and the display level of each pixel can be adjusted by the voltage applied to the X electrode. It is also desirable to place a color filter on the display side to enable color display.

[0032] (2-2) Configuration of controller 20 Next, the configuration of the controller 20 will be described. First, the hardware configuration of the controller 20 will be described.

[0033] (2-2-1) Hardware configuration of controller 20 FIG. 7 is a block diagram showing the hardware configuration of the controller 20. As shown in FIG. As shown in FIG. 7, the controller 20 includes a processor 21, a memory 22, a storage 23, a communication IF 24, and an input / output IF 25.

[0034] The processor 21 is hardware for executing an instruction set written in a program stored in the memory 22, and is composed of an arithmetic unit, a register, peripheral circuits, and the like. The processor executes a program related to the management application to perform, for example, the following processes. Processing information related to the light source 11, such as light intensity and wavelength, input to the user terminal 5 Processing related to the generation of images displayed by video output devices Processing related to emission of fine particles from the fine particle emission device 30 A process for determining the amount of control for each device based on user information input from the user analysis device 40 These processes will be described in detail later.

[0035] The memory 22 is for temporarily storing programs and data to be processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory). The programs include, for example, the following programs: ·OS (Operating System) programs - Programs that are downloaded and stored in memory to control each device Web browser program that processes information

[0036] The storage 23 is a storage device for saving data, such as a flash memory, a hard disc drive (HDD), or a solid state drive (SSD).

[0037] The communication IF 24 is an interface for inputting and outputting signals so that the system 1 can communicate with an external device. Specifically, the communication IF 24 desirably uses a module compatible with a general-purpose communication standard.

[0038] The input / output IF25 functions as an interface with an input device (e.g., a pointing device such as a mouse, a keyboard) for receiving input operations from the user, and an output device (a display, a speaker 63, etc.) for presenting information to the user. The controller 20 may be, for example, open source hardware or an industrial CPU board.

[0039] (2-2-2) Functional configuration of controller 20 Next, a description will be given of the functional configuration of the controller 20. FIG. The controller 20 functions as a communication unit 201 , a storage unit 202 , and a control unit 203 . The communication unit 201 performs processing for the controller 20 to communicate with an external device.

[0040] The storage unit 202 stores data and programs used by the controller 20. The storage unit 202 stores treatment protocols, voice command data, and treatment content.

[0041] The treatment protocol is data regarding the control of each device when performing a treatment. The voice command data is data in which the contents of control for each device of the system 1 are associated with the user's spoken voice. The treatment content is data including video data (light stimulation) and audio data (sound stimulation) that are output to the user when the treatment is performed.

[0042] The control unit 203 functions as a transmission / reception unit 2031, a content generation module 2032, a content output module 2033, a device control module 2034, a noise detection module 2035, and a user analysis module 2036 by the processor 21 of the controller 20 performing processing according to a program.

[0043] The transmission / reception unit 2031 controls the process in which the controller 20 transmits a signal to an external device in accordance with a communication protocol, and the process in which the controller 20 receives a signal from an external device in accordance with the communication protocol.

[0044] The content generation module 2032 generates treatment contents that are optical and acoustic stimuli. For example, when the system 1 is used in the treatment of dementia, the treatment contents are composed of video data and audio data whose intensity oscillates at a blinking frequency close to gamma waves. The treatment contents do not need to include audio data. In this description, the blinking frequency refers to the frequency at which the maximum peak is obtained in the frequency spectrum obtained by Fourier transforming the waveform of the change in illuminance over time. The blinking frequency of the treatment contents is preferably less than 100 Hz. That is, in the system 1, the light source 11 irradiates blinking light with a blinking frequency of less than 100 Hz in at least a part of the area.

[0045] That is, the content generation module 2032 converts the video data and audio data contained in the video content material into a blinking frequency of less than 100 Hz. The content generation module 2032 also converts the audio content into an audio signal modulated according to a predetermined cycle. The converted audio signal is output by the content output module 2033. A specific method for generating the treatment content will be described later.

[0046] Here, in the system 1, the treatment content may be generated in advance using the content generation module 2032. In this case, the content output module 2033 outputs a blinking video signal as a video from the video output device. On the other hand, in the system 1, the content output module 2033 may perform output control for general video content, which will be described later, to output the content from the light stimulation device 10 and the sound stimulation device 60. In this case, it is not necessary to generate treatment content.

[0047] When the treatment content has already been generated, the content output module 2033 outputs the treatment content from the light stimulation device 10 and the sound stimulation device 60 as is. On the other hand, when the treatment content has not yet been generated, the content output module 2033 controls the output modes of the light stimulation device 10 and the sound stimulation device 60 when outputting the video content as the material. That is, the content output module 2033 controls the blinking frequency of the light stimulation and sound stimulation output from the light stimulation device 10 and the sound stimulation device 60 to be less than 100 Hz, which is a preset predetermined frequency band.

[0048] The content output module 2033 controls the blinking frequency of the light source 11 so that it falls within a preset predetermined frequency band. When adjusting the intervals between lighting and blinking of the light and providing light stimuli of different frequencies, it is necessary to control ON / OFF of the light source 11. Also, a means for adjusting the light intensity while the light is ON is required.

[0049] As a specific example, a control method will be described in which the content output module 2033 applies a light stimulus in the gamma band of 25 to 100 Hz from an LED light source. Fig. 9 is a diagram showing the pulse waveform of light output at a gamma frequency. This diagram shows examples of pulse waveforms of 25 Hz, 40 Hz, and 100 Hz with a duty ratio (proportion of ON time in one cycle) of 50%, respectively.

[0050] As shown in Figure 9, when turning on and off repeatedly at a fixed cycle, if the duty ratio is 50%, the ON time varies within a range of 5 to 20 msec. The following methods can be used to adjust the amount of light emitted during this ON time. -Methods for controlling the current flowing through LEDs, OLEDs (organic light-emitting diodes), etc. How to adjust the ON time length (duty ratio) -How to include PWM control in the ON time

[0051] However, when controlling the current flowing through LEDs, OLEDs (organic light-emitting diodes), etc. in stages, it is necessary to switch the circuit every time the current is changed, making the control circuit complex. For this reason, the content output module 2033 adjusts the length of the ON time and applies PWM control to the ON time. Fig. 10 is a diagram showing the pulse waveform of light generated by applying PWM control during lighting.

[0052] 10, when the content output module 2033 generates a light stimulus of a gamma frequency while adjusting the light amount by PWM control, "light irradiation by PWM control" and "light-off" are repeated at 10 to 40 msec per cycle. In addition, it is desirable that the frequency used for PWM control is 60 Hz or more, similar to the general display light source.

[0053] FIG. 11 is a diagram comparing pulse waveforms of light amount adjustment by PWM control and light amount adjustment by only the ON time interval. As shown in Figure 11, when the light intensity is not adjusted by PWM control, the interval visually recognized as the "light emission time" is shorter than when the light intensity is adjusted by PWM control. This tendency is more noticeable when the required light intensity is small, and when an image is projected onto a display, the time to recognize the image is shorter, which may result in the user being unable to clearly recognize the video content.

[0054] For this reason, it is desirable for the content output module 2033 to adjust the light intensity of the light source 11 by PWM control during the ON time. Also, considering that a past study on optical stimulation of gamma frequencies showed that the duty ratio of the optical pulse was 50% or less, it is desirable for the OFF time interval to be at least 5 msec, which is 50% of the 100 Hz cycle.

[0055] In other words, in generating a light stimulus of a gamma frequency, it is desirable to repeat a certain light ON / OFF pattern with one cycle of 10 to 40 msec, and to include "a period of time in which the light is continuously off for 5 msec or more" in one cycle. Such control by the content output module 2033 can be used not only for LEDs but also for other light sources 11 such as OLEDs.

[0056] The device control module 2034 shown in FIG. The controls performed by the device control module 2034 include the following. Control of releasing fine particles from the fine particle releasing device 30 Control of outputting skin stimulation from the skin stimulation device 70 - Controlling the operation of various IoT devices used in System 1

[0057] The noise detection module 2035 uses the sensing data of the optical sensor 81 to detect optical noise entering the environment (bathroom) in which the system 1 is used. Furthermore, the noise detection module 2035 detects sound noise entering the environment (bathroom) in which the system 1 is used, using sensing data relating to sound sensed by the microphone 64 of the smart speaker 61 (see FIG. 16).

[0058] The user analysis module 2036 analyzes the state and behavior of the user using the sensing data of the user analysis device 40. The sensing process performed by the user analysis device 40 will be described later.

[0059] (2-2-3) Method for generating treatment content Next, a method for generating treatment contents (light stimuli and sound stimuli) by the content generation module 2032 will be described. First, video content can be general still images such as photographs, illustrations, and paintings, as well as videos of movies and natural scenery. As file formats, image files such as JPEG, PNG, GIF, PSD, and TIFF, and video files such as AVI, MOV, WMV, and MPEG can be used as video content. In other words, the content generation module 2032 converts the video content into a video signal that blinks at a predetermined cycle.

[0060] In addition to video content, audio content such as music, natural sounds, radio, and podcasts can be used. Audio file formats include MP3, WAV, AIFF, AAC, FLAC, and Opus.

[0061] A method for generating treatment content output at gamma frequencies by the content generation module 2032 will now be described. When generating light and sound stimuli outputted at gamma frequency, the content generation module 2032 controls ON / OFF of the light source 11 and sound source, adjusts the intervals of turning on and off the light source 11 and the sound ON / OFF, and generates light and sound stimuli of different frequencies. Fig. 12 is a diagram showing an example of a method for generating treatment contents.

[0062] The example shown in FIG. 12 explains an algorithm for generating treatment content (light stimuli, sound stimuli) in the gamma band from video data with audio. As shown in Figure 12, when generating content that provides light and sound stimuli in the gamma band of 25 to 100 Hz, for example, a process can be used to insert intervals of light OFF (black screen) and sound OFF at equal intervals in a cycle of 10 to 40 msec. This process can convert general video content with sound into treatment content (light and sound stimuli). In addition, by processing the video and sound collectively in this way, the phases of the light and sound stimuli can be easily aligned.

[0063] FIG. 13 is a diagram showing a process of inserting light and sound OFF. As shown in FIG. 13, there are two ways to insert light and audio OFF. - Cutting out the original video and audio and inserting OFF (see the left side of Figure 13) A method of compressing the original video and audio by, for example, double the playback speed, and inserting OFF periods according to the shortened time (right side of Figure 13) Considering that it is recommended that the duty ratio of the light pulse be 50% or less for gamma frequency light stimulation, it is desirable that the OFF time interval be at least 5 msec, which is 50% of the 100 Hz cycle.

[0064] Next, a method for correcting the treatment content will be described. As a first example of correction of the treatment content, the timing of the light stimulation and the sound stimulation included in the treatment content can be shifted when the treatment content is actually output from the system 1. In such a case, the insertion position of OFF of one of the light stimulation and the sound stimulation can be offset with respect to the insertion position of OFF of the other.

[0065] For example, if there is a 5 msec phase difference between the neural excitation of a user in response to light stimulation and the neural excitation in response to sound stimulation, the phase of the induced neural excitation can be aligned by offsetting the sound stimulation by 5 msec relative to the light stimulation. Since the phase difference of neural excitation varies from person to person, it can be adjusted for each user.

[0066] Next, as a second example of correcting the treatment contents, a process of correcting a portion that is not suitable for treatment will be described. For example, the brightness of a part of the image of the treatment content may be outside the range suitable for treatment, or the volume of a part of the treatment content may be outside the range set for treatment. In such cases, the intended effect may not be obtained by using the treatment content.

[0067] Therefore, the video data and audio data included in the treatment content are scanned, and error portions where the brightness or volume is outside the appropriate range are corrected so that they fall within the appropriate range. Specifically, one of the following processes is performed as shown in Fig. 14. Fig. 14 is a diagram showing a process of detecting and correcting a portion unsuitable for treatment from treatment content. -Replace the erroneous portion with the video or audio from the original data (video data with audio) - Correct the brightness of the error area - Correct the volume of the error part

[0068] Although the method of generating the treatment content has been described by inserting OFF into both the video and audio files, the insertion process may be performed in only one of the files. Also, the ON / OFF of light and sound has been described as a method of newly generating data of treatment contents from audio-accompanying video data, but it may be performed by controlling the output device (video output device and speaker 63). For example, if the video output device has a backlit liquid crystal display, the treatment contents can be output by controlling the ON / OFF of the backlight and speaker 63 without processing the data into audio-accompanying video data.

[0069] Furthermore, even if the video output device displays a black screen, if the backlight is on, optical noise will occur, which may reduce the effectiveness of the treatment. Therefore, it is desirable to use a system that controls the lighting of the backlight in accordance with the image. In high-performance LCD displays, the backlight is controlled to be turned off when the image is in black. By using a similar system, the backlight is also turned off when a black image is displayed, preventing optical noise.

[0070] (2-3) Configuration of the fine particle emission device 30

[0071] The particle emission device 30 shown in FIG. 5 emits particles into a spatial region where the light source 11 irradiates light. The fine particle emission device 30 applies energy from the outside to a liquid or solid to generate fine particles. The fine particle emission device 30 applies energy to water, oil, and inorganic matter to turn them into fine particles. The energy applied by the microparticle group emission device 30 may be various types of energy such as ultrasonic waves, electricity, heat, etc.

[0072] As shown in Fig. 1, the fine particle emitting device 30 is provided with a mist generator 32 used in mist saunas and the like as an appliance for generating mist. A hot water supply section 31 in which hot water is stored is connected to the mist generator 32. Fig. 15 is a diagram showing the structure of a head section 33 of the mist generator 32 provided in the fine particle emitting device 30. 15, a plurality of nozzles that turn water into mist and emit it are formed in the head portion 33 of the mist generator 32. The head portion 33 emits mist from each nozzle when hot water is supplied thereto. Note that cold water may be supplied to the head portion 33 of the mist generator 32 instead of hot water.

[0073] A water supply valve as an IoT device having a communication control function for turning on / off the hot water supply may be provided in the hot water supply unit 31 for the mist generator 32. By communication-controlling the hot water supply, for example, using a voice recognition function of the user terminal 5, the mist generator 32 can be made to automatically start generating mist. Also, the fine particle emission device 30 may generate mist in the bathroom by emitting hot water from a shower, without emitting mist from a mist generator. However, considering that complex visual effects can be obtained by the Brownian motion of the mist, it is preferable to use the mist as the fine particle emission device.

[0074] (2-4) Configuration of the user analysis device 40 The user analysis device 40 shown in FIG. 5 has a function of detecting any one of the user's position, posture, line of sight direction, and sleep state. The user analysis device 40 includes an image sensor such as a CMOS, a CCD, etc. The user analysis device 40 includes, for example, a USB camera with a pixel count of about 100,000 to 10 million pixels.

[0075] The user analysis device 40 measures the user's position, body movement, face direction, eye opening and closing, etc. to analyze the user's condition. By analyzing the user's condition, the user analysis device 40 can determine whether the user is looking away from the light stimulus or closing their eyes, and can evaluate whether the treatment is being performed properly.

[0076] Moreover, a radio wave sensor that detects the blinking of the user can be used as the user analysis device 40. In this case, there is no need to capture images like a camera, which is advantageous in terms of user privacy.

[0077] Other examples of user analysis device 40 that can be used include a system that determines the user's location using an infrared distance sensor, an obstruction sensor, or an ultrasonic motion sensor, and a system that predicts when the user will fall asleep by measuring the body surface pulse wave. The mounting position of each sensor constituting the user analysis device 40 may be on the video output device, but it may also be placed at any position in the room, such as on a light or window.

[0078] Furthermore, when the system 1 is used in a bathroom as in this embodiment, a sensor installed in the bathtub 100 may be used as the user analysis device 40 as a means for monitoring the state of the user during treatment. For example, a sound sensor, pressure sensor, or temperature sensor that detects the user's breathing, pulse, body movement, body temperature, etc., may be used as the user analysis device 40 to prevent accidents such as falling asleep while bathing. This makes it possible to issue an alarm sound from the speaker 63 or perform processing to call for safety confirmation when an abnormality is detected in the user's heart rate, breathing sound, body temperature, etc.

[0079] (2-5) Configuration of voice recognition device 50 and sound stimulation means The voice recognition device 50 has a function of recognizing the user's spoken voice. The sound stimulation means has a function of outputting a stimulation having a certain periodicity and inputted to the user via the sense of hearing. In this embodiment, a smart speaker 61 in which a voice recognition device 50 and a sound stimulation means are integrally formed will be described.

[0080] In the system 1, it is desirable to adopt a waterproof bath pillow type smart speaker 61 as the smart speaker 61 that can be used in the bathroom. As shown in Fig. 1, the smart speaker 61 is placed in a part of the bathroom that is located at the head of a user who enters the bathtub 100. Fig. 16 is a diagram showing the structure of the bath pillow type smart speaker 61.

[0081] As shown in FIG. 16, a bass pillow type smart speaker 61 includes a support part 62 that supports a head, and a pair of audio output parts arranged on either side of the head. Each of the pair of audio output units has a built-in speaker 63 and a microphone 64. The pair of left and right speakers 63 are disposed in positions close to both ears of the user who uses them. In addition, the sound stimulation means has a built-in sound sensor.

[0082] In this way, the smart speaker 61 is placed in a position that supports the head of the user who uses it, and therefore can smoothly provide the user with sound stimulation from a position close to the user's ears. In addition, since it is desirable to provide the user with sound stimuli under conditions that eliminate sound noise as much as possible, a shape that covers the user's ears from both the left and right, as shown in the figure, is desirable.

[0083] The smart speaker 61 performs at least the following functions by having the internal processor execute voice application software. - Voice control function that recognizes user spoken commands -Remote control of each device and surrounding IoT devices These functions allow the user to instruct the start of treatment by speaking, without using the user terminal 5. Furthermore, by providing a biometric authentication function such as a voiceprint authentication function, the user using the system 1 can be identified, making it possible to call up a treatment protocol specific to that user.

[0084] The voice recognition means and the sound stimulation means may be separate devices instead of the bass pillow type smart speaker 61. For example, in addition to the voice recognition means equipped with a microphone 64, waterproof headphones or earphones, or a bone conduction speaker 63, etc. may be used as the sound stimulation means.

[0085] The smart speaker 61 may also be equipped with an ultrasonic motion sensor, an infrared sensor, a human sensor, a contact sensor, a strain sensor that detects changes in the shape of the device due to contact by the user, etc. Using these sensors, it is possible to detect that the user's head is near the speaker 63 and confirm that the position of the user's head is appropriate, thereby preventing problems such as excessive sound stimulation caused by the user's ears being too close to the speaker 63.

[0086] (2-6) Configuration of skin stimulation device 70 The skin stimulation device 70 outputs a stimulation having a certain periodicity by electricity or ultrasound, which is input to the user via the sense of touch. Note that the skin stimulation device 70 may combine electrical stimulation and ultrasound stimulation.

[0087] A device that uses electrical stimulation to treat a neurological disorder can be used as the skin stimulation device 70. Such devices include devices of various structures, such as wristwatch type, earphone type, headband type, bedgear type, eyeglasses type, nose plug type, mouthpiece type, and patch type.

[0088] In particular, by adopting a device that applies gamma frequency electrical stimulation as the skin stimulation device 70 and combining it with treatment using gamma frequency light and sound stimulation, it becomes possible to induce oscillations (neural vibrations) that are effective in preventing and treating dementia and improving cognitive ability. In fact, treatments using 40 Hz electrical stimulation to the head of subjects have already been carried out using these devices, with the aim of improving cognitive ability.

[0089] (3) Other devices and software Other devices and software that can be used simultaneously with System 1 will be described.

[0090] (3-1) Configuration of Illumination Device 80 The lighting device 80 in the space (a bathroom in this embodiment) in which the system 1 is installed is an IoT device that is remotely controlled by a communication function. The lighting device 80 is operated by inputting to the user terminal 5 using a communication function compatible with various communication standards such as Bluetooth (registered trademark). To avoid optical noise, it is necessary to turn off the indoor lights when applying gamma frequency light stimuli using the system 1. For this reason, to save the user the trouble of manually turning off the lights, a lighting device 80 is used as an IoT device with a communication function.

[0091] (3-2) Configuration of the optical sensor 81 An optical sensor 81 is provided in the space in which the system 1 is installed. The optical sensor 81 has a communication function and measures the amount of light (i.e., optical noise) in the space in which the system 1 is installed and in which the user receives treatment when the lights are turned off. The optical sensor 81 is an IoT device that transmits detected data to the user terminal 5 by the communication function. The optical sensor 81 may be built into any of the devices used simultaneously, such as the liquid crystal display, the sound stimulation means, and the lighting.

[0092] (3-3) Configuration of User Terminal 5 The system 1 may be operated by a user terminal 5. The user terminal 5 is a terminal on which various application software can be installed and operated. Specifically, a desktop PC, a smartphone, a VR device, an AR device, or the like can be adopted as the user terminal 5. Examples of application software that the user terminal 5 installs include the following. ·Management application for managing system 1 · A voice application that manages a smart speaker 61 (voice recognition device 50 · sound stimulation device 60) - Applications for remotely controlling other IoT devices The user terminal 5 is preferably equipped with a Graphical User Interface (GUI) such as a touch panel for operating applications and checking data, etc. Considering ease of operation and the popularity of such devices, a general-purpose smartphone is suitable.

[0093] (3-4) Waterproofing means Furthermore, the system 1 may be provided with a waterproofing means. Specifically, it is desirable for the light source 11 and the image display unit 12 to have waterproof and dustproof properties. For this reason, it is desirable to use a completely sealed structure that is used in outdoor displays, for example.

[0094] (3-5) Anti-fogging measures The system 1 may also include a means for preventing fogging. Since a clearer image can be displayed if no water droplets are formed on the image surface, it is desirable for the image display unit 12 to take measures to prevent fogging caused by the adhesion of mist generated by the mist generator 32. For this reason, it is desirable to use a hydrophilic or hydrophobic film or coating agent on the image surface of the image display unit 12. Also, for example, a hydrophilic film or coating that can smooth water droplets by spreading may be used.

[0095] (3-6) Configuring the management application Next, the management application of the system 1 will be described. Application software used on PCs, smartphones, etc. can be used as an application to manage the content of treatments using light and sound stimulation. For example, application software compatible with general-purpose smartphones can be used as the management application. Fig. 17 is a diagram showing an example of a display screen of the management application.

[0096] As shown in FIG. 17, it is desirable for the display screen of the management application to have a menu for managing treatment protocols, such as content data used for light and sound stimulation, and a menu for managing treatment logs. The user selects the following from the treatment protocol management menu: Content data used for the treatment (type of video data, image data) Irradiation time -Brightness and intensity range of light stimuli output from the display -Intensity range of sound stimulation output from speaker 63 This allows the user to set up a treatment protocol according to their desired behavior.

[0097] In addition, the user can check the history of the procedures he or she has performed from the procedure log management menu. In addition, the user can check, for example, the degree of achievement of a target total procedure time. This can increase the motivation of the user to continue the treatment. In addition, in order to make the management application available on multiple devices, an application in which data is stored on the cloud server 82 is preferable.

[0098] (3-7) Cloud Server 82 The system 1 is communicatively connected to a cloud server 82 via a network. The cloud server 82 stores at least a treatment protocol for each user and a log related to the treatment.

[0099] (4) System 1 Processing Next, the process when a user uses the system 1 will be described. FIG. 18 is a diagram showing the state of data communication when the system 1 is in use. As shown in FIG. 18, the management application of the user terminal 5 transmits the treatment protocol selected by the user and the voice command set by the user to the controller 20, and these are stored in the storage unit of the controller 20.

[0100] When a voice command is input to the smart speaker 61 by a spoken voice from the user, the voice application inputs the voice command to the controller 20. The controller 20 controls each device according to a treatment protocol associated with the voice command.

[0101] The controller 20 outputs a log of the action to the management application. The management application transmits the following data to the cloud server 82: Action Log Data on the user's status analyzed by user analysis means The cloud server 82 stores each transmitted data.

[0102] FIG. 19 is a diagram showing a process for using the system 1. First, in the system 1, a user's voice is registered (step S101). Specifically, in order for the smart speaker 61 to identify the user, the user registers his or her own voice in a voice application.

[0103] The user logs in to a voice application (hereinafter, voice application) of the smart speaker 61 from the user terminal 5, and registers his / her own voice information on the voice application started up on the user terminal 5. For example, by uttering words specified by the voice application to the user terminal 5, the characteristics of the user's voice are stored in the voice application.

[0104] The voice application performs data communication with the smart speaker 61 through wireless communication conforming to a general-purpose communication standard. The voice application transmits user voice information to the smart speaker 61 together with device information such as the device name and a device-specific address, enabling identification of the user by voice in subsequent operations.

[0105] After step S101, the user operates the user terminal 5 to link the voice application with the management application (step S102). Specifically, the voice application is linked to the management application of the system 1, and the voice information of the user registered in the voice application is linked to the user's identification information in the management application (such as a user's unique user ID).

[0106] This operation makes it possible to call up a treatment protocol corresponding to the voice when the user inputs a voice instruction to the smart speaker 61. The voice application and the management application may be integrated into one application.

[0107] After step S102, the user operates the user terminal 5 to perform pairing between the smart speaker 61 and another device (step S103). Specifically, the smart speaker 61 is paired with the controller 20, that is, communication settings are made for transmitting commands from the smart speaker 61, so that an instruction to start a process can be transmitted from the smart speaker 61 to the controller 20 when the user issues a spoken instruction to the smart speaker 61. Similarly, pairing is also made between the smart speaker 61 and other IoT devices (such as the water supply valve of the mist generator, the lighting device 80, and the light sensor 81).

[0108] After step S103, the user operates the user terminal 5 to set a treatment protocol and a voice command (step S104). Specifically, the user logs into the management application from the user terminal 5 and selects the details of the treatment protocol (video and audio content, amount of mist, treatment time, etc.). For example, if you are undergoing treatment while taking a bath in the evening, you can prevent disruptions to your circadian rhythm, which is your biological rhythm that follows a 24-hour cycle, by selecting video content with less blue, such as a sunset.

[0109] Next, the user sets a voice command for calling the selected treatment protocol on the management application. The voice command may be a combination of the name of the smart speaker 61 and a command, such as speaking "start treatment" after the name of the smart speaker 61. A command for interrupting or ending the treatment may also be set.

[0110] In addition, when setting the voice command, a plurality of combinations of treatment protocols and voice commands may be set so that the treatment protocol corresponding to the voice command can be called up. The management application transmits the set treatment protocol and voice command from the user terminal 5 to the controller 20. These data are stored in the memory unit of the controller 20, and each device becomes ready to start treatment. Note that the processes from step S101 to step S104 can be omitted when the system 1 is used for the second time or later.

[0111] After step S104, the user issues a verbal instruction to start the treatment (step S105). Specifically, after entering the bathtub 100 in the bathroom in which the system 1 is installed, the user inputs a voice command by speaking into the microphone 64 built into the smart speaker 61 to instruct the start of treatment. At this time, the voice application transmits the voice command to the controller 20.

[0112] After step S105, the system 1 checks the user's location (step S106). Here, if the user is not positioned appropriately, the following problems are expected to occur. - The user may not be positioned properly, which could result in ineffective light stimulation. -If the user is not positioned properly, excessive sound stimulation may occur. To prevent these problems, the user's position is sensed by a sensor mounted on the smart speaker 61. The user analysis module 2036 of the controller 20 analyzes the sensed information. The sensor that checks the user's position may be mounted on a light source 11, indoor lighting, etc., or may be installed as a standalone user analysis device 40, but it is more effective to mount it on a smart speaker 61 located close to the user's head.

[0113] In step S106, if the user is not in the appropriate position (No in step S107), the system 1 prompts the user to move to an appropriate position (step S108). Specifically, the user analysis module 2036 of the controller 20 causes the speaker 63 of the smart speaker 61 to output a voice alert indicating that the user's position is not appropriate. After that, the user's position is confirmed again (step S106).

[0114] On the other hand, if it is determined in step S106 that the user is in an appropriate position (Yes in step S107), the system 1 turns off the lights and checks for noise (step S109). Specifically, the device control module 2034 of the controller 20 turns off the lighting device 80. Then, the noise detection module 2035 of the controller 20 acquires sensing data from the optical sensor 81 and checks whether there is any optical noise that may interfere with the treatment. In addition, the noise detection module 2035 acquires sensing data from the microphone 64 of the smart speaker 61 and checks whether there is any sound noise that may interfere with the treatment.

[0115] If there is optical noise or sound noise that interferes with the treatment (Yes in step S110), the noise detection module 2035 prompts the user to block light and sound by outputting a sound alert from the smart speaker 61 (step S111). In addition, the sound noise may be reduced by the noise canceling function of the speaker 63.

[0116] On the other hand, if there is no optical noise or sound noise that would interfere with the treatment (No in step S110), the treatment is carried out (step S112). Specifically, the content output module 2033 of the controller 20 outputs light stimuli according to the protocol from the video output device. At the same time, the content output module 2033 outputs sound stimuli from the smart speaker 61. The content output module 2033 outputs selected treatment content to the user according to the contents set in the treatment protocol. In addition, the device control module 2034 of the controller 20 controls the particle group emission module to emit the particle group into the bathroom.

[0117] Here, while the procedure is being performed, the user analysis module 2036 of the controller 20 analyzes the user's condition. FIG. 20 is a diagram illustrating the process of analyzing a user's state. As shown in FIG. 20, the user analysis module 2036 checks the user's position and face direction (step S121).

[0118] In step S121, if the user's position and face orientation are not within the appropriate range (No in step S122), the user analysis module 2036 outputs an alert from the smart speaker 61 to prompt the user to move to an appropriate position.

[0119] On the other hand, in step S121, if the user's position and face orientation are within the appropriate range (Yes in step S122), the user analysis module 2036 does not output an alert. Thereafter, the content output module 2033 and the device control module 2034 of the controller 20 continue the process (step S124).

[0120] When the treatment corresponding to the treatment protocol selected in step S112 is completed, the system 1 completes the treatment and stores the data (step S113). Specifically, when the treatment time set in the treatment protocol is reached, the content output module 2033 of the controller 20 ends the output of the treatment content. The control unit of the controller 20 generates a treatment log and transmits it to the management application of the user terminal 5, and the transmitted data is stored in the cloud server 82 via the network. This completes all the processing in the system 1.

[0121] In addition, the bathroom-based system 1 described above may be used not only to treat dementia, but also to treat other health conditions such as seasonal affective disorder (SAD), winter depression, jet lag, retinal disease, pain suppression, and wellness improvement.

[0122] (5) Summary As described above, in the system 1 according to the first embodiment, optical stimuli are output to the user by the optical stimulation device 10. Therefore, by stimulating concentration and reducing the number of blinks, the amount of light entering the user's eyes per certain period of time can be increased, thereby improving the effectiveness of the treatment. In addition, since the treatment content is generated from general video content, it is possible to generate treatment content that is preferred by each of the users, who have individual differences in taste.

[0123] In addition, even if a user gets tired of a particular treatment content, new treatment content can be generated according to the user's preferences. In other words, unlike conventional treatment light such as a constant blinking light, it is possible to provide the user with a new light stimulus that is preferable to the user and allows for switching. This makes it possible to provide treatment content that has a high therapeutic effect and can be used continuously by the user.

[0124] In addition, the image display unit 12 can display a variety of images to suit the diverse preferences of the user, and the mist can change the light transmission and reflection pattern three-dimensionally, and visual targets can be created other than the display surface. With these means, the user can receive treatment using light stimulation comfortably while enjoying the changes with a sense of realism.

[0125] Furthermore, the particles such as mist and bubbles emitted by the particle emission device 30 cause Brownian motion in a medium such as air or water, scattering the light stimuli output by the video output device, providing a visual "fluctuation" to the user. Brownian motion is a phenomenon commonly seen in nature, but does not generally occur in artificial objects, so the particles fluctuating due to Brownian motion have favorable psychological effects on the user, such as a "natural feel," a "relaxing effect," and a "restored focus."

[0126] For this reason, because the microparticles create an atmosphere close to nature, it is expected that the image will give the user a realistic impression even if the resolution of the image (light stimulus) output by the image output device is low. In addition, while devices such as liquid crystal displays are prone to deterioration due to strong light, the microparticles are generated and disappear on the spot, so there are no problems due to deterioration.

[0127] In addition, unlike flat displays, the particles create a sense of depth, making it difficult for the viewpoint to become fixed. When the user looks at the light stimuli scattered by the particles, it is expected that this will have the effect of relieving eye fatigue. In addition, the patterns created by the light reflected by the particles are constantly changing, providing visual effects such as rainbows and vortexes at random times, stimulating the user's anticipation of accidental aesthetic pleasure (activating the brain's reward circuitry) and helping them maintain concentration.

[0128] Furthermore, by adding fragrances or chemicals to the hot water supplied as microparticles, it is possible to add a scent or impart deodorizing or bactericidal effects, so air purification and deodorizing effects can also be expected. In addition, it is possible to provide users with tactile stimulation that cannot be obtained through video alone, such as the sensation of touching groups of fine particles carried by the air currents in the space in which the device is being used.

[0129] In addition, when the system 1 is used in a bathroom, the act of soaking in the bathtub 100 is part of daily life, and the user can prevent dementia by using existing habits without having to acquire new habits. In this regard, since it is difficult for busy users to make new time for prevention, there is a great advantage in terms of saving the user's time and making prevention a habit. In addition, there is an advantage in using the system 1 in a bathroom in that water and hot water, which are the raw materials for the fine particles, are easily available, and there is no harmful effect of releasing the fine particles into the air.

[0130] In addition, since the system 1 has a user analysis device 40, it is possible to check the user's position and face orientation before performing a treatment such as optical stimulation. If the user is outside the range suitable for treatment, it is possible to control the system by, for example, encouraging the user to move to an appropriate position or correcting the position of the light source 11. In addition, the user analysis device 40 can measure the distance between the user and the light source 11 and adjust the light intensity according to the distance, and can also measure the frequency with which the user blinks, making it possible to evaluate the user's level of concentration during treatment.

[0131] (6) Variations Modifications of each of the above-mentioned devices will now be described.

[0132] (6-1) Modifications of the light source 11 FIG. 21 is a diagram showing a modified example of the light source 11. In FIG. As shown in FIG. 21, a light source 11 according to a modified example has a surface structure that utilizes a scattering plate 11C and a reflecting plate 11B. The light source 11 has a scattering plate and a reflector 11B arranged side by side in the front-rear direction. A plurality of LEDs are provided on both the left and right sides of the scattering plate 11C. The scattering plate 11C scatters the light from the LEDs, and the reflecting plate 11B reflects the scattered light toward the scattering plate 11C side, so that the light source 11 as a whole irradiates light forward.

[0133] The light source 11 may use light of multiple wavelengths. In this case, it is preferable to arrange LEDs with different wavelengths evenly. LEDs with different wavelengths may be arranged on each of the four sides of the scattering plate 11C, i.e., top, bottom, left, and right. For example, when using blue, green, and red LEDs, it is desirable to use LEDs with the following peak wavelengths. Blue: Around 480 nm (can be effective in regulating circadian rhythms, etc.) Green: Around 525 nm (can be expected to be effective in suppressing pain, etc.) Red: Around 670 nm (potentially effective for activating cells)

[0134] Alternatively, an organic light emitting diode (OLED), in which an organic substance emits light, may be used as the light source 11. Alternatively, a laser diode can be used. For example, a method can be used in which a structure combining a laser diode and a light guide rod is arranged vertically to create a surface light source. Furthermore, as the light source 11 other than the LED and OLED, various light sources 11 such as a xenon lamp, a halogen lamp, a deuterium lamp, a mercury lamp, an excimer lamp, and an incandescent lamp can be used.

[0135] Instead of the light source 11 and the image display unit 12, a light-emitting display can also be used. In a light-emitting display such as an organic EL display or a plasma display, the pixels of the display emit light, so that the display itself can be used as the light source 11. In addition, in plasma displays, cells coated with phosphors are arranged in a grid pattern on the display surface. A discharge phenomenon is caused in each cell to generate ultraviolet light, which excites the phosphors to emit light. By using phosphors that emit light with wavelengths suitable for optical treatment, they can be effectively used as optical stimuli for treatment.

[0136] When using a field emission display, it can also be used as an optical stimulus for treatment by using a phosphor that emits light of a wavelength suitable for treatment as an illuminant that is irradiated with an electron beam when a voltage is applied. Alternatively, a micro LED display having a structure in which an LED is arranged for each pixel may be used.

[0137] Alternatively, a display may be used in which an LED array is rotated at high speed and emits light in time with the LED array passing a specific position, creating an afterimage that can be viewed as an image. In addition to being used as a 2D display like a television or PC monitor, these displays can also be used for VR devices and 3D displays. In that case, a stereoscopic image can be generated by displaying images for the right and left eyes, respectively.

[0138] Also, a projector that projects an image onto a projection surface can be used as light source 11. FIG. 22 is a diagram showing the positional relationship when a projector is used as light source 11. As shown in Figure 22, when a projector is used as light source 11, the user does not look directly at light source 11, but rather sees an image projected onto a screen, panel, or the like. The projector may be an early CRT type that projects an image created by a cathode ray tube onto a screen. In this case, light with a wavelength suitable for the treatment is projected onto the screen. To ensure the amount of light required for the treatment, it is desirable to use a screen that is highly reflective, such as white.

[0139] The micro LED display may also be used as a projector. In this case, a projector using quantum photonic imaging (QPI) technology is particularly preferable because it can project high-resolution, high-brightness images in a small size. Each pixel of a QPI display has a three-layer structure of red, green, and blue light-emitting elements, with a logic circuit on the bottom and a light-guiding structure on the top. Suitable objects for projection include a user's hand or the translucent display of AR glasses.

[0140] When a QPI display is used in the system 1, it is desirable to select and use a light-emitting element with a wavelength suitable for the treatment. In addition, devices such as AR glasses that reflect light close to the user's eyes require less light for treatment compared to when light is projected from a distance, making them suitable for use with small projectors for treatment.

[0141] FIG. 23 is a diagram showing a state in which treatment light is projected from a projector onto the group of fine particles. As shown in Fig. 23, in addition to the output of the light stimulus from the video output device, another image may be projected from the projector onto the particle group. In this case, the image projected onto the particle group becomes an additional light stimulus. When performing treatment using the gamma frequency light stimulus, it is desirable to blink the light stimulus projected by the projector and the treatment light source output from the video output device in synchronization.

[0142] In addition, when a small projector using a micro LED or the like is used as the light source 11, a wearable device such as AR glasses equipped with a small projector is also included in the image output device. Fig. 24 is a schematic diagram of AR glasses equipped with a small projector. As shown in Figure 24, smart glasses equipped with two small projectors on the sides can be used as a video output device.

[0143] The small projectors are placed on the lens side of each of the left and right temples of the glasses. The small projector irradiates treatment light toward a lens formed by a partially transparent plate. The treatment light is reflected by the lens and projected as an image into the eye box, a space where the image can be clearly seen. Another option is to install a small projector in the watch and project images onto the palm of your hand or other parts of your body.

[0144] A near-infrared light source of 700 to 1400 nm (typical peak wavelengths are 850 nm, 940 nm, and 1064 nm) may be added to the light source 11 described above. Near-infrared light is known to have effects such as improving health by activating mitochondrial function, inhibiting aging, and improving the condition of the retina.

[0145] (6-2) Modifications of the image display unit 12 A passive type liquid crystal display may be used as the image display unit 12 instead of the above-mentioned active type liquid crystal display. In a passive type liquid crystal display, transparent electrodes are arranged to sandwich an alignment film in which liquid crystal is sealed. By adopting the passive type, the structure becomes simple, which is advantageous in terms of cost. By arranging a color filter on the display side, it can be used as a color liquid crystal display.

[0146] Alternatively, an electro-wetting panel may be used as the liquid crystal display. In this case, the wettability of the surface of the water-repellent insulating layer of each pixel is changed by applying a voltage, and the shape of the oil contained in the pixel is changed to control the transmission of light.

[0147] When no voltage is applied, the oil covers the surface of the water-repellent insulating layer, blocking the light from the backlight. However, when a voltage is applied to the transparent electrode, the surface of the insulating layer becomes hydrophilic, repelling the oil and allowing the light from the backlight to pass through. By switching the light transmission on and off for each pixel, it is possible to display images. To display color, it is possible to use oils of multiple colors or to layer color filters.

[0148] Alternatively, an electrochromic panel may be used as the liquid crystal display, in which case the color of each pixel is changed by electrical stimulation (application of voltage) to control the wavelength of light that passes through. The panel has a structure similar to that of passive LCD displays, with cells sandwiched between transparent electrodes from above and below, and when a voltage is applied to the transparent electrodes, the redox state of the color-producing layer formed on the electrodes changes, causing it to emit color. By making each cell emit color individually, it is possible to display a desired image. Metal oxides are often used as materials for the color-developing layer, and well-known examples include tungsten oxide (WO3), Prussian blue, NiO, and Ir(OH)x.

[0149] Recently, electrochromic panels have been developed that can express a wider variety of colors by stacking different color-producing layers and adjusting the color of each layer. For example, a panel has already been successfully manufactured that combines a layer of SVO (stabilized vanadium oxide) with a layer of tungsten oxide, and changes color two-dimensionally depending on the combination of voltages applied to each layer. Using such technology, the wavelength of transmitted light can be precisely controlled.

[0150] In addition, the aforementioned organic EL panel itself serves as the light source 11. However, since there is a disadvantage that the life span of the panel is shortened when it emits strong light, the light source 11 may be provided separately, and a transparent organic EL panel may be used as a liquid crystal display that transmits the treatment light irradiated from the light source 11. In this case, two methods can be used to make the OLED display transparent: sandwiching it between transparent electrodes from above and below, as in passive LCD displays, or providing a transparent area between the OLED cells that allows light to pass through. When providing gaps between organic EL cells, a structure in which transparent cells are arranged to separate rows of RGB cells, for example, can be considered. You may control it.

[0151] In this way, the liquid crystal display combined with the light source 11 in the video output device can be used as a 2D display such as a television or PC monitor, as well as a VR device or a 3D display. In that case, it becomes possible to generate a stereoscopic image by displaying images for the right eye and the left eye, respectively.

[0152] The treatment light transmitted through the transmissive display may be displayed on a screen or panel. In this case, the light source 11 and the transmissive display function as a projector. When a projector using a transmissive display such as a transmissive liquid crystal panel is used, the light source 11 is placed at a position corresponding to the light source 11 of the projector. For example, in the case of a color projector using a transmissive liquid crystal panel, the light emitted from the light source 11 is separated into red, green, and blue by a dichroic mirror, and the images of each color created by the transmissive liquid crystal panel are synthesized and projected from a pair of lenses.

[0153] For color display, instead of splitting the image with a dichroic mirror, a method of lighting up LEDs of different colors may be used. Also, a monochromatic image may be projected. Also, the transmissive panel may use image display means other than liquid crystal, such as an electrowetting method or an electrochromic method.

[0154] As described above, the modification of image display unit 12 may be configured integrally with light source 11 like a general display, but may also be configured separately from light source 11. Furthermore, the light irradiated to the light transmission control portion does not have to be directly irradiated from the light source 11, but may be irradiated via a reflector or the like.

[0155] For example, it is possible to use a mechanism that does not transmit backlight, like electronic paper, as the optical stimulation device 10, and that controls the reflection pattern of light irradiated from the front. For example, one of the earliest examples of electronic paper was a reflective panel based on the Gyricon beads method, which uses solid particles painted in two colors, called Gyricon beads.

[0156] The top and bottom of the Gyricon beads are painted black and white, and are negatively and positively charged, respectively. The bead rotates due to the charge of the electrode (driver layer) in contact with the bead, switching between black and white. By controlling this for each pixel, it is possible to display images. It is also possible to produce a color display by using beads in a combination of colors other than black and white, or by stacking color filter layers.

[0157] Alternatively, electronic paper with an electrophoretic reflective panel may be used. In electrophoretic panels used in electronic paper, etc., two colored pigment particles, each positively and negatively charged, and microcapsules containing oil are used as pixels. By applying a voltage to the electrodes above and below the microcapsule, one color of pigment moves to the display side. By doing this for each pixel, it is possible to display an image. Color images can also be displayed by using pigments of different colors such as RGB or by stacking color filter layers.

[0158] Also, electronic paper equipped with an electronic liquid powder type reflective panel may be used. Unlike electrophoretic panels, electronic powder panels do not use oil, but have a structure in which two colored electronic powder particles, each positively and negatively charged, move through the air. In this structure, applying a voltage to the upper and lower electrodes of the cell causes one color of electronic powder to move to the display side. By doing this for each pixel, it is possible to display an image. Color images can also be displayed by using electronic powders of different colors such as RGB, or by overlaying color filter layers.

[0159] In addition to the above, liquid crystal panels having various structures as described above (for example, electrowetting type or electrochromic type panels, or transparent organic EL panels) may be used as image output devices by disposing a reflector on the back of the panels.

[0160] Furthermore, a reflective liquid crystal on silicon (LCoS) projector may be used as the image output device. When a reflective liquid crystal projector is used as the light stimulation device 10, light is reflected by a reflective liquid crystal panel and then projected as an image through a lens.

[0161] For example, in a three-panel LCoS projector, the light emitted from the light source 11 is separated into red, green, and blue by a dichroic mirror, and the images of each color created by the reflective LCD panel are synthesized and projected through a pair of lenses. For color display, instead of using dichroic mirrors to separate the images, it is also possible to use LEDs of different colors, or to limit the number of colors to one and project a monochrome image. As the reflective panel, in addition to liquid crystal, electrowetting type, electrochromic type, gyricon bead type, electrophoretic type, and electronic powder type panels may be used.

[0162] Furthermore, a DLP (Digital Light Processing) type projector may be used as the video output device. When using a DLP projector as an image output device, light is reflected by the DLP chip (also known as the Digital Micromirror Device; DMD) and then projected as an image through a lens. The DLP chip is equipped with tiny mirrors equal to the number of pixels, and by changing the direction of the mirrors, the display of each pixel can be controlled to be turned on or off.

[0163] For example, in an RGB color DLP projector, the light emitted from the light source 11 passes through a color wheel that rotates at high speed, and is reflected by the DLP chip and projected as an image. A color image can be synthesized by superimposing the images generated for each RGB color. For color display, instead of a color wheel, you could use high-speed switching red, green, and blue LEDs, or you could limit the display to one color and project a monochrome image.

[0164] In addition, AR glasses that generate images using a laser light source and a reflector may be used as the image output device. When projecting an image directly onto the retina rather than observing an image projected onto a screen or panel, a system using a laser light source can be used as the image output device.

[0165] For example, a technology is known in which light emitted by an RGB laser is reflected off a MEMS mirror and a reflector, and the angle of the MEMS mirror is quickly adjusted to project an image onto the user's retina. In this case, the MEMS mirror and the reflector serve as a reflective image display unit 12 , and the RGB laser serves as a light source 11 .

[0166] The image output device may also project an image as the treatment light onto a transparent medium, i.e., the image output device outputs an image projected onto a medium such as a partially reflective panel. In this case, a light source 11 for optical stimuli is provided in addition to a projector that projects a general image onto a screen or the like, and the user sees the light from the light source 11 and the image projected by the projector at the same time.

[0167] Specific mechanisms that can be used include the projector and AR glasses mentioned above. The image output device may also project an image onto the particle cluster, which will be described later. When using blinking light as treatment light, it is desirable to make the image on a projector such as a projector blink in synchronization with the blinking of the treatment light.

[0168] (6-3) Modifications of the fine particle emission device 30 Next, a modified example of the fine particle emission device 30 will be described. The fine particle emission device 30 of the system 1 is not limited to the mist generated from the hot water by the mist generator 32 described above, and various fine particle groups can be used. The types of fine particle groups, generation means, and possible means for controlling the spatial arrangement of the fine particle groups are described below.

[0169] (6-3-1) Solid fine particles The particulate emission device 30 may emit solid particulates. Materials for the solid particles can include plant materials such as the bark of the tabu tree, which is used in incense sticks, and tobacco leaves. Ice particles can also be used under low-temperature conditions. When burning to generate smoke, additives such as fats and oils to aid combustion and adhesives to solidify the material can be used.

[0170] Alternatively, the fine particle emission device 30 may emit a dry powder for use in a dry powder inhaler (DPI).

[0171] Specifically, sugar alcohols, polyols, crystalline sugars, inorganic salts, organic salts, etc. can be used as components of carrier particles. On the other hand, examples of active particles having medicinal properties include the following. Steroids, bronchodilators, nitrates, antihistamines, anti-inflammatory agents, anticholinergic agents, leukotriene receptor antagonists, antiallergic agents, antiemetics, hormones, sympathomimetics, opioids, analgesics, immunomodulators, hypoglycemic agents, anesthetic agonists, opiate antidotes, phosphodiesterase inhibitors, seinhibitor), antidepressants, serotonin agonists, serotonin antagonists, adrenergic agonists, adrenergic neuron blockers, benzodiazepines, antibiotics and antibacterial agents, antibacterial agents, antiviral agents, vaccines, immunoglobulins, local anesthetics, antispasmodics, angiotensin converting enzyme inhibitors, angiotensin II receptor blockers, α-blockers, antiarrhythmic agents, anticoagulants, potassium channel regulators, cholesterol lowering agents, diuretics, smoking cessation agents, bisphosphonates, dopamine agonists, nucleic acid medicines, antipsychotics Other pharma- ceutically acceptable salts or derivatives of any of the above.

[0172] As a method for generating fine particles, for example, the following method can be used. Mechanical crushing of solids - Method of releasing air from a nozzle by pressurizing it - Heating the material and burning it, releasing it as smoke When fine particles are generated by combustion, the fine particles that are carbonized from the material are carried upward by the rising air currents caused by heating.

[0173] (6-3-2) Liquid particles As a representative example of the liquid fine particles, the mist of fine particles of hot water (water) described above can be used. Instead of the mist generator 32, the fine particle group emitting device 30 may include the following device as a device for generating mist. - Ultrasonic atomizer that uses ultrasonic vibrators to break up liquids Fog machine that cools and discharges heated liquid A spraying device that simultaneously sprays pressurized air and liquid from a nozzle The fine particle emission device 30 may also use a method of atomizing water in the air or in the surrounding area, or water vapor in the air, using dry ice. The particle emitting device 30 can also be used to atomize liquids such as alcohol and oil.

[0174] The fine particle emission device 30 may also emit a scented mist used in electronic cigarettes, etc. Generally, electronic cigarettes have a structure in which a liquid containing a flavoring such as mint or coffee is heated and atomized, and then supplied as a mist. As a specific example of the raw material components of the fine particles, a liquid in which a flavoring is mixed with propylene glycol, glycerol, etc. can be used. As examples of the flavoring, fruity scents, herbal scents, and woody scents can be used. Both natural and artificial flavoring substances can be used.

[0175] The fine particle emission device 30 may use a solution containing a medicinal ingredient used in a pressurized metered dose inhaler (PMDI). Specific components of the solution may be those obtained by dissolving the various medicinal ingredients described above in a solvent such as alcohol. Salts such as acetates and benzenesulfonates may also be used. The particulate mass emission device 30 may also emit a mixture of the solid and liquid particulates described above.

[0176] Furthermore, the system 1 may use water droplets discharged from a shower or flowing water such as a fountain as the microparticle group by placing the water within the irradiation range of the light source 11.

[0177] (6-3-3) Gas particles in liquid Furthermore, the particles used in the system 1 are not limited to those floating in the air. Gas particles floating in a liquid may also be used as the particles. Specifically, a technique can be used in which an aerator is installed as a fine particle emission device 30 on the bottom of the bathtub 100, and air bubbles are generated in accordance with the image projected on the water surface. In addition to air, carbon dioxide gas and nitrogen gas can also be used as components of the air bubbles.

[0178] As a method for generating such bubbles, a method in which gas taken in by a motor-type or piezoelectric diaphragm pump is released into the liquid can be used. In addition, the following method can be used to create fine bubbles such as microbubbles and nanobubbles. -Ultrasonication method A method that uses plasma called excimer laser ablation - Method using emulsification Inkjet printing method The microbubbles and nanobubbles thus released into the bathtub 100 undergo Brownian motion in the hot water of the bathtub 100 and remain for a long time, making them suitable for creating visual effects due to their irregular movement.

[0179] The system 1 may also use liquid particles (such as oil in water) that separate from the solvent, or solid particles (such as metal powders and resin powders) in the liquid. When magnetic particles or liquids are used, it is also possible to control their behavior by magnetism. It is also possible to use an aquarium containing aquatic animals, seaweed, plankton, etc. as a device for scattering the treatment light.

[0180] (6-4) Particle Group Control Device 34 Furthermore, the system 1 may include a particle group control device 34 that controls the spatial arrangement of the particle group released by the particle group release device 30 so as to keep the particle group at an appropriate position. The particle group control device 34 can use a technique for controlling the movement of the particle group or a technique for removing the particle group as a method for controlling the spatial arrangement of the particle group. Specific examples are described below.

[0181] (6-4-1) Structural control measures The movement of particles can be restricted by providing a physical barrier such as a partition. For example, a cup-shaped structure can be used to accumulate particles inside, or a box-shaped or cylindrical structure can be used to keep particles in a specific location.

[0182] (6-4-2) Control methods using air flow and liquid flow A flow generating means can be used as a method for directing the particles released into the air to a desired location or for removing them. For example, a fan can be used as a means of generating airflow. It is preferable to use a fan that is moisture-proof and dust-proof so that it can be used in environments filled with fine particles such as fog. In addition, a compressor or vacuum pump can be used to generate positive and negative pressure to create a flow.

[0183] In addition, technology that releases a mass of gas can be used as a means of transporting a group of particles to a specific location. For example, a technology that releases gas in a vortex shape can be used. The aforementioned aromatic components or active particles with medicinal properties can be used as ingredients to be contained in the released gas.

[0184] When magnetic particles are used, it is also possible to use an electromagnet or a ferrite magnet as a means for controlling the flow of the particles in the direction of movement.

[0185] In addition, when creating a liquid flow, an underwater motor can be used, and when using a magnetic fluid as the liquid, an electromagnet or ferrite magnet can be used as a means for controlling the flow.

[0186] (6-4-3) Means for removing fine particles By removing the fine particles and leaving the fine particles in the area where they are not removed, it is also possible to control the area in which the fine particles float. Specific removal methods are described below. Infrared radiation can be used to remove particles such as fog and ice particles by heating them. Carbon fiber heaters and infrared semiconductor lasers can be used as infrared radiation sources. It is also possible to irradiate gas particles in a liquid with infrared light, heating the gas and causing the bubbles to expand, causing them to rise to the liquid surface and be removed.

[0187] There is also a method of using discharge in gas to block the flow of solid particles. For example, a mechanism can be used in which a high voltage is applied to a needle electrode and an attractor electrode, and an ion wind (a flow of ionized dust or gas molecules) is generated by emitting electrons from the needle electrode. Ionic wind can also be used to make liquid particles condense and fall as water droplets. For example, ion wind could be used to irradiate fog, causing water droplets to fall and creating the appearance of rain. On the other hand, in addition to the infrared rays mentioned above, other methods of removing air bubbles from liquids include a method of expanding and removing the air bubbles using heat or negative pressure, a method of shrinking the air bubbles using pressure to make them invisible, or a method of dissolving the bubbles in the liquid.

[0188] (6-5) Particle Recognition Device 35 Furthermore, the system 1 may include a particle group recognition device 35 that recognizes the positional state of the particle group released by the particle group release device 30 in order to grasp the positional state of the particle group and to keep it in an appropriate position. The particle group recognition device 35 is provided with an image sensor such as a CMOS or a CCD in order to observe the arrangement state of the particle groups.

[0189] The particle group recognition device 35 may be, for example, a USB camera with a pixel count of about 100,000 to 10 million pixels. The particle group recognition device 35 records an image before the particle groups are generated as an initial state, compares the image after the particle groups are generated with the initial state, and recognizes the range of the particle groups from the difference in RGB values ​​for each pixel.

[0190] Furthermore, the particle group recognition device 35 may recognize an area where fog exists (or an area where fog does not exist) by using an infrared distance sensor, an interruption sensor, an ultrasonic motion sensor, or the like. In these cases, the mounting position of each sensor may be on the device used for the light treatment, or may be any position in the room, such as a light or a window. Furthermore, the particle group recognition device 35 may utilize a camera mounted on a general-purpose indoor robot.

[0191] (6-6) Modifications of anti-fogging means A liquid or gas spray can be used to remove fogging or dirt from the image output device. For example, a mechanism for spraying a cleaning liquid can be used. Other available mechanisms include a mechanism that blows dry or hot air, a mechanism that sucks up dirt using negative pressure, and a mechanism that physically removes water droplets and dust using a wiper.

[0192] (6-7) Modifications of the voice recognition device 50 Instead of the smart speaker 61, the voice recognition device may be a tablet, smartphone, PC, or the like that is operated via a touch panel or the like. In addition, a device that recognizes the user's position and movement may be used as a trigger for starting or ending treatment. For example, there are known IoT devices that can detect user actions using image sensors such as CMOS, ultrasonic motion sensors, infrared sensors, human presence sensors, etc., and operate other devices such as lighting. These devices may be used to start and end the optical treatment of the present invention. For example, it is possible to start treatment by detecting that the user has woken up.

[0193] (6-8) Modifications of treatment contents Next, a modified example of the processing content will be described.

[0194] (6-8-1) Content for VR devices and stereoscopic displays The treatment content may be a content for a VR device or a stereoscopic display. In such a case, the content generation module 2032 generates image data for the left eye and the right eye separately. The content output module 2033 displays each image on the display of the VR device or the stereoscopic display as a video output device, so that the user can use the stereoscopic video as content. In particular, images that are highly effective in enticing the user to pay attention include, in addition to natural landscapes, "flames," "paintings," "photographs of people," "photographs from the user's album," "stock price charts," and "patterns."

[0195] (6-8-2) Game Content The treatment content may be a video game or other content. A liquid crystal display, an organic electroluminescence display, or the like may be used as a device for displaying game images.

[0196] (6-8-3) Modification of the treatment content generation method FIG. 25 is a diagram showing a method for generating treatment contents according to a modified example. As shown in FIG. 25, in the method for generating contents for treatment according to the modified example, a contents generating module 2032 generates contents for treatment by embedding images and sounds. That is, the content generation module 2032 generates treatment content by inserting prepared image and audio files into the ON portion of template data in which ON / OFF timing is arranged at a constant cycle.

[0197] By adopting this generation method, it is possible to randomly play back photos from a user's album, for example. The treatment content obtained by this generation method has the disadvantage of being less varied than videos, but it has the advantage of being simple in structure, saving file size, and providing uniformity of stimulation.

[0198] Furthermore, the content generation module 2032 may perform color conversion on the video data of the treatment content in order to irradiate light with a wavelength suited to the purpose. The content generation module 2032 performs processing to change the color tone of images and videos in order to enhance specific wavelengths in order to improve the effects of light treatment. For example, to generate content for treatment using red light, a process of converting green and blue parts to red can be used. More specifically, processes such as converting tree leaves from green to red to express autumn leaves, or converting blue skies to red to express a sunset can be used.

[0199] In addition, the system 1 may use the emitted particle group to perform visual effects on the treatment content. For example, clouds, smoke, etc. can be expressed using particle group emitted in front of the image screen of the video output device. In this case, the content generation module 2032 causes the particle group emission module to accumulate particle groups such as fog in front of the video output device.

[0200] That is, when a picture of the sky with clouds is output from a video output device, the content generation module 2032 grasps the relative spatial area in which the clouds exist in the picture. Then, the content generation module 2032 makes the particle group emission device 30, the particle group control device 34, and the particle group recognition device 35 each execute a control program for controlling the emission and arrangement of the particle group so that the particle group floats in the grasped spatial area.

[0201] FIG. 26 is a diagram showing an example of visual presentation of treatment content by a group of fine particles. As shown in Fig. 26, when the image (target image) to be shown to the user is screen X, the content generation module 2032 causes the particle group emission module to execute control regarding emission of the particle group so that the particle group floats below the image. Such control of the arrangement of the particle group will be described in detail below. Fig. 27 is a diagram showing the state of screen X in Fig. 26.

[0202] FIG. 27 is a diagram showing the state of the system 1 corresponding to the screen X in FIG. As shown in Figure 27, when clouds are located below, fine particles are generated below and accumulated. When the fine particles are mist, they tend to move in the direction of gravity, so if there is a part that can serve as a receiver, the mist can be accumulated in the target area without airflow control or removal.

[0203] FIG. 28 is a diagram showing the state of the system 1 corresponding to the screen Y shown in FIG. As shown in Figure 27, when clouds are located at the top, the particles are also generated at the top. When the particles are fog, a suction fan is used to move the fog upwards to prevent it from flowing downward, and the fog that has flowed off the screen is removed by infrared rays, making it appear as "clouds floating in a fixed position."

[0204] In these examples, it is desirable to display the background image variably on a display or the like, but it is also possible to represent the sun or moon by placing a spherical light source 11 in front of a fixed background such as a painting, or to represent the scenery using three-dimensional models of mountains, trees, etc. In addition, the infrared irradiator used to control the shape of the mist may function not only to remove the mist but also as a heater to warm the user's body.

[0205] Furthermore, in the system 1, fine particles in the liquid may be used to provide a visual effect to the treatment content. For example, when accumulating particles such as air in a liquid, the position at which the particles are to be accumulated can be specified using a target image or the like, as in the above-mentioned processing, and the particles can be generated, moved, removed, etc. so that they are accumulated at the specified position.

[0206] The position where the particles are to be accumulated can be read from the target image, or the user can specify a new position for the particles to be accumulated. For example, the user can use the software's drawing function to draw a picture of clouds in the image content to be displayed, and generate a control program that creates and removes fog in an arrangement that corresponds to the drawn cloud position.

[0207] The target image may be either a 2D image or a 3D image. When performing control in accordance with a 3D image, it is necessary to control the generation, movement, and removal of the particle group in a more complicated manner. For this reason, it is desirable to provide multiple means for controlling the spatial arrangement of the particle group, or to provide an actuator for moving the spatial arrangement control means.

[0208] (6-9) Modifications of the user analysis device 40 Next, a description will be given of modified examples of the user analysis device 40. Here, a configuration in which various wearable devices are used as the user analysis device 40 will be described. When the user is wearing a wearable device, the wearable device can be used as a user analysis device 40, and control such as interrupting treatment can be performed when an abnormality in the user is detected based on biometric information obtained from the wearable device.

[0209] (6-9-1) Watch-type wearable devices The user analysis device 40 may be a smart watch capable of acquiring biometric information of the user. In this case, the user analysis device 40 can, for example, measure heart rate, breathing rate, blood oxygen concentration, blood pressure, body temperature, etc., estimate blood volume, etc. In particular, the heart rate and breathing rate are indicators of the user's mental state and concentration state, and can be used to understand the compatibility between the user and the treatment content. They can also be used to check the safety of the user by checking whether there are any abnormalities in their breathing or heart rate.

[0210] In addition, many smartwatches are also equipped with the ability to operate external devices, so they can also be used as terminals for starting and ending treatments. Furthermore, when a smartwatch equipped with a CMOS sensor, CCD, spectrometer, hyperspectral camera, or the like is used as the user analysis device 40, a log of the wavelengths of light the user is exposed to during the day can be obtained. Then, it is possible to grasp the tendency according to the user's lifestyle, for example, excessive exposure to blue light or insufficient exposure to light during the day. Therefore, the log of the wavelengths of light the user is exposed to during the day can be used when recommending suitable treatment for the user.

[0211] (6-9-2) Glasses and contact lens-type wearable devices As the user analysis device 40, a wearable device such as glasses or contact lenses can be adopted. For example, a device shaped like glasses and capable of tracking the view seen by the user with a mounted camera or the like can be adopted as the user analysis device 40. By using this, during the treatment of the system 1, the user analysis device 40 can acquire information such as whether the user is actually looking directly at the light, the actual intensity of the light input to the user, or the health condition of the user's eyes.

[0212] Also, for example, a device capable of grasping eye activity such as blinking by a camera, an infrared sensor, or an electrooculogram (EOG) sensor may be adopted as the user analysis device 40. In this case, it is possible to grasp whether the user is concentrating on observing the light during the light treatment of the system 1.

[0213] A wearable device having a function for testing each area of ​​the retina may also be used as the user analysis device 40. In this case, the condition of the retina can be tested for each area. The same device can also be used as a red light irradiation device, so that red light therapy can be performed only on areas where the condition of the retina has deteriorated.

[0214] In addition, when smart glasses equipped with a CMOS sensor, CCD, spectrometer, hyperspectral camera, etc. are used as the user analysis device 40, a log of the wavelengths of light to which the user is exposed during the day can be obtained. In this configuration, the log of the wavelengths of light to which the user is exposed during the day can be measured at a position closer to the eye than with a smartwatch-type user analysis device 40, so the wavelengths of light that enter the user's eye can be measured more accurately.

[0215] Furthermore, a contact lens type wearable device may be employed as the user analysis device 40. In this case, it is possible to measure the concentrations of melatonin, interleukin-6, and the like contained in tears. Furthermore, when the system 1 is used for circadian rhythm regulation or treatment of Seasonal Affective Disorder (SAD), the phase of the user's circadian rhythm estimated from the measurement results can be used as reference data for determining the timing of treatment.

[0216] In addition to the above, various wearable devices such as earphone type, headphone type, and clothing type can also be used as the user analysis device 40. In addition, various types of biometric sensors mounted on bedding, a toilet, a bathtub 100, etc. can also be used as the user analysis device 40.

[0217] (6-10) Other devices Next, other devices that can be added to the system 1 will be described.

[0218] (6-10-1) Light-shielding device The system 1 may further comprise a shading device. In treatments that require timing when light does not enter the eye, such as gamma frequency light stimulation, light entering through a bathroom window, for example, can become noise and adversely affect the effectiveness of the treatment. For this reason, it may be necessary to use a light-shielding device to prevent the intrusion of light noise.

[0219] An example of a light-blocking device is a remote-controlled window that uses an electrochromic system to control the light transmittance. When a voltage is applied to a transparent electrode, the oxidation state of the color-forming layer changes, causing the window to change color, blocking external light. Moreover, the light blocking device may be a shutter or blinds with an automatic opening and closing function.

[0220] (6-10-2) Sound insulation devices The system 1 may further comprise a sound insulating device. For example, when a user receives sound stimuli from a wearable device used as earphones or headphones, the wearable device can also function as a sound-blocking device by adopting a wearable device with a noise canceling function.

[0221] Furthermore, when the user receives sound stimuli from a distant position, the speaker 63 having a spatial noise canceling function can be used so that the speaker 63 also functions as a sound insulation device. In this case, for example, the sound insulation device estimates the sound noise that reaches the user's ear from the input information of the sound sensor and the user's position information, and generates a sound with the same amplitude and opposite phase as the sound noise to cancel the noise. Additionally, structures such as soundproofing materials may be employed as sound insulating devices.

[0222] (6-10-3) Indoor robots The system 1 may further include an indoor robot. Robots that support safety management and communication in homes and offices may be used in the system 1. Various sensing functions installed in these robots may be used for sensing the state of the user implemented in the present invention. For example, an indoor robot may monitor the user during treatment to ensure that they do not fall or have abnormal breathing, and sound an alarm if an abnormality occurs. These robots may also monitor the spatial arrangement of the aforementioned particle groups, observe the direction of the user's face and whether their eyes are open or closed, and operate other devices.

[0223] (7) Other uses Next, a configuration in which the system 1 is used in a place other than the bathroom will be described.

[0224] (7-1) Use in the toilet FIG. 29 is an external view of the system 1 when used in a toilet. As shown in Fig. 29, when the system 1 is used in the toilet, it has the same configuration as when it is used in the bathroom described above. Then, other devices are operated by a user's voice command to the smart speaker 61. The specific process flow in this case is the same as the process described above.

[0225] Here, the effect of the smart speaker 61 is maximized when it is placed close to the user's ears, just like in a bathroom, so it is desirable to place it above the backrest of the toilet. In addition, since getting wet is a bigger problem in a toilet than in a bathroom, it is preferable that the fine particle emission device 30 be an ultrasonic atomizer that can generate mist gently.

[0226] In addition, toilets are used more frequently than bathrooms, and are used many times a day, so the contents of the treatment protocol may be changed each time. For example, it is possible to irradiate the user with light stimuli with wavelengths that correspond to the change in wavelength of sunlight depending on the time of day. It is also desirable for the video content to be displayed in accordance with the time of day.

[0227] Furthermore, when the system 1 is used in a toilet, a biological information sensor installed on the toilet bowl that comes into contact with the user may be used as the user analysis device 40. For example, a technology can be used to monitor the user's condition using a blood concentration sensor, pressure sensor, potential sensor, etc. installed on the toilet seat. By using these technologies, it is possible to obtain the user's health data during treatment, detect abnormalities in the user, and sound an alarm.

[0228] In addition, since the time spent using the toilet varies each time, the user may input a voice command to stop the treatment before the time set in the treatment protocol is reached, and the treatment may be terminated. In addition, the treatment may be terminated when a motion sensor or a contact sensor detects that the user has stood up. The toilet system described above may be used for gamma stimulation therapy, as well as for the prevention and treatment of other health conditions, such as seasonal affective disorder, winter depression, jet lag, retinal disorders, pain suppression, and wellness improvement.

[0229] (7-2) Use in entertainment facilities such as discos and karaoke booths FIG. 30 is an external view of the system 1 when used in an entertainment facility such as a disco or karaoke booth. In addition to a display, a discos typically uses multiple stage lights and speakers 63. In this example, the display and stage lighting output light stimuli by synchronizing the gamma frequency and cycle timing. Whether there is any deviation in the light and sound stimuli generated for each device is checked by looking at the waveforms of the light sensor 81 and microphone (sound sensor) 64 installed on the display, etc., and the content generation unit of the controller 20 corrects by applying an offset.

[0230] Furthermore, when the system 1 is used in a disco, a fog machine used in stage equipment and the like can be used as the fine particle generating device. Fog machines create large amounts of mist by heating liquid (such as a mixture of ethylene glycol and water) supplied from a tank and then discharging it while cooling it, making them suitable for use in large spaces such as discos.

[0231] In addition, since constantly generating gamma frequency light and sound stimuli may tire the user, it is possible to provide timing for generating gamma stimuli between music and video playback, similar to that of a regular disco. One method for aligning the timing of stimulus generation is to attach a timestamp to the data and synchronize the output timing of multiple devices. For example, if the content generation unit attaches a timestamp to each of the video content and audio content, it becomes possible to output both light and sound stimuli from multiple devices in a synchronized manner.

[0232] (7-3) Use in the bedroom System 1 can also be used to regulate circadian rhythms to treat or prevent Seasonal Affective Disorder (SAD) and winter depression. Many SAD patients suffer from a lack of light, which causes a decline in energy, and early morning light exposure is a solution. FIG. 31 is an external view of the system 1 when used in a bedroom. As shown in FIG. 31, when used for circadian rhythm regulation, the system 1 is installed in a bedroom.

[0233] FIG. 32 is a diagram showing the process when the system 1 is applied to circadian rhythm regulation. In the circadian rhythm adjustment, first, a management application for the light stimulation treatment is set (step S201). Specifically, the user logs into the management application from the user terminal 5 and sets the target wake-up time and the details of the treatment protocol (video content, amount of mist, treatment time, etc.). Here, in circadian rhythm regulation, it is desirable to irradiate light having a light intensity of 1000 to 5000 Lux, which is used in general phototherapy, and light having a wavelength of about 480 nm as the light stimulus. In order to obtain a sufficient amount of light, a high-brightness liquid crystal display is suitable for the image display unit 12.

[0234] In addition, in the circadian rhythm adjustment, a morning atmosphere can be created by selecting, for example, a sunrise image as the processing content. It is preferable to use mist generated by an ultrasonic atomizer as the fine particle group generated in front of the display. The management application transmits the set treatment protocol to the controller 20. The data is stored in the memory of the controller 20, and the controller 20 is ready to start the treatment.

[0235] After step S201, a treatment protocol is executed (step S202). Specifically, when the set wake-up time arrives, the content output unit drives the video output device to generate light stimuli according to the protocol. The light stimuli themselves also function as an alarm clock, facilitating the user's awakening. Furthermore, in order to promote the user's awakening, sound may be output from the sound stimulation device 60, or gas may be released in a vortex shape. For example, a vortex ring of air scented with a citrus fruit or the like that promotes awakening may be supplied to the vicinity of the user's face.

[0236] After step S202, the system 1 records data during the treatment (step S203). Specifically, since the user may close his / her eyes when waking up, the user analysis device 40 analyzes the user's behavior to check whether the treatment is being performed normally. For example, the user analysis device 40 uses a camera to record the user's face direction and eye movement, as well as the amount and time of light that was irradiated when the user's eyes were open. In addition, the user's concentration level is evaluated by measuring the number of blinks per certain period of time.

[0237] Here, if the user is wearing a wearable device, data such as heart rate and blood oxygen saturation obtained from the wearable device may be simultaneously acquired. By grasping the stress felt by the user during treatment from data such as heart rate and accumulating it as data, a treatment protocol suitable for the user can be grasped. In addition, control such as interrupting treatment may be performed when an abnormality of the user, such as a sudden increase in heart rate, is detected.

[0238] After step S203, the system 1 completes the procedure and stores the data (step S204). Specifically, the controller 20 ends the operation of each device when the treatment time set in the protocol is reached. A treatment log is transmitted from the controller 20 to the management application, and the transmitted data is stored in the cloud server 82 via the network.

[0239] This use of System 1 in the bedroom can be used to treat not only SAD and winter depression, but also other health conditions such as dementia, jet lag, retinal disorders, pain management, and improved wellness.

[0240] Next, a method for monitoring the effect of the light stimulation treatment will be described. In order to understand the effects of the above treatment, a wristwatch-type wearable device as the user analysis device 40 or sensors built into the bedding can be used to measure body temperature, pulse rate, heart rate, blood pressure, breathing sounds, etc. From this data, the timing of falling asleep and waking up can be understood, and the phase of the user's circadian rhythm can be estimated.

[0241] The data from these sensing devices can be accessed from a management application installed on the user terminal 5. By knowing whether the user's sleep onset and wake-up rhythm is approaching the target, the effectiveness of the treatment can be monitored. Because the timing of sleep onset and wake-up varies from day to day, it is desirable to compile data for about one week to one month and evaluate the average and median values.

[0242] Furthermore, when a contact lens type wearable device is used as the user analysis device 40, it is also possible to measure the concentrations of cortisol, interleukin-6, etc. in tears. This is because the phase of the circadian rhythm is clinically identified by measuring the changes over time in melatonin concentration and cortisol concentration, and can be grasped by testing the user's saliva, blood, etc.

[0243] Other methods that use electrodes attached to the body, such as electroencephalography (EEG), electrooculography (EOG), electromyography (EMG), and electrocardiography (ECG), can also be used to accurately monitor sleep. However, these methods require cumbersome procedures such as sampling bodily fluids and attaching electrodes, making them difficult to use on a daily basis, so sensing using wearable devices is preferable.

[0244] In addition, in the case of diseases such as SAD, in which multiple factors, such as serotonin disturbances in addition to circadian rhythm disturbances, are involved, symptoms may not improve even if the phase misalignment of the circadian rhythm is eliminated. On the other hand, by using System 1, it is possible to report that the phase shift of the circadian rhythm has been resolved using data accumulated as a treatment log, thereby providing doctors and other medical professionals with information to consider other treatment methods, such as medication.

[0245] In addition, the system 1 can be used to prevent or treat jet lag, delayed sleep phase syndrome (DSPS), advanced sleep phase syndrome (ASPS), etc. When treating ASPS, it is preferable to perform light stimulation treatment in the evening or at night rather than early in the morning.

[0246] (7-4) Using System 1 to improve cognitive performance with red light Other applications of System 1 include photobiomodulation therapy (PBMT) with red and infrared light, and improving cognitive performance. PBMT is a therapy that aims to inhibit retinal aging, repair damage, and prevent and treat diabetic retinopathy (DR) and age-related macular degeneration (AMD).

[0247] In the case of the light stimulation treatment using red light, first, the management application for the light stimulation treatment is set up as in FIG. The user logs into the management application from the user terminal 5 and sets the details of the treatment protocol (video content, amount of mist, treatment time, etc.). In this case, the optical stimulus is light in the red region (620 to 760 nm), particularly light with a wavelength of 670 nm, which is scattered by the fine particles, and it is desirable that the image input to the user be an image with a lot of red, such as a sunrise or sunset. It is also desirable to use light in the near infrared region (780-825 nm), especially light with a wavelength of 810 nm. A liquid crystal display is suitable as a mechanism that can utilize a high-brightness red LED.

[0248] As a specific treatment content, it is desirable to display an image that goes well with artificial clouds made of fine particles, such as a sea of ​​clouds at sunset. Also, since it is known that red light irradiation in the morning (especially light of 630 nm) improves cognitive ability when waking up and is effective against sleep inertia, it is also possible to display image content that mimics a sunrise in the early morning. It is preferable to use mist generated by an ultrasonic atomizer as the fine particle group generated in front of the display.

[0249] The management application sends the set treatment protocol to the controller 20. The controller 20 stores this data in its memory and is ready to start treatment. Next, the system 1 executes the treatment protocol, records data during the treatment, completes the process, and stores the data in the cloud server 82, similar to FIG. 32 above. Here, since PBMT is effective not only for improving the condition of the retina of the eye, but also for improving the condition of the body, such as muscle damage, it may be used in a bathroom to improve the condition of the entire body, including the eyes. In this case, the bathroom described in the embodiment related to the treatment of dementia can be used.

[0250] To understand the effects of the red light treatment, visual acuity tests can be conducted using an application on a smartphone or retinal tests can be conducted using a wearable eyeglass device. In addition, more accurate diagnostic results can be obtained by undergoing tests at a medical institution, such as visual acuity tests, fundus examinations, retinal imaging diagnostics, and contrast sensitivity (CCS) tests.

[0251] (7-5) Method of using the present invention to suppress pain by green light Other uses of the system 1 include treatment with green light for the purpose of suppressing pain in episodic migraine (EM), chronic migraine (CM), post-operative pain, etc. In this explanation, as in FIG. 31, we will assume a user who is recuperating after surgery, and explain the configuration for use on a hospital bed.

[0252] In the light stimulation treatment using green light, first, the management application for the light stimulation treatment is set up as in FIG. The user logs into the management application from the user terminal 5 and sets the details of the treatment protocol (video content, amount of mist, treatment time, etc.). In this case, light with a wavelength in the green region (490 to 550 nm), particularly around 525 nm, is irradiated as the light stimulus. In addition, since strong light can cause pain, it is desirable to irradiate light with low luminance of 300 Lux or less. As a display, in addition to a liquid crystal display, an organic EL display or the like is also suitable.

[0253] As a specific treatment content, it is desirable to use images with a lot of green, such as forests. It is desirable to use fog generated by an ultrasonic atomizer as the fine particles generated in front of the display, to create the appearance of a "foggy forest." The pain-suppressing effect can be further improved by using, as the components of the fine particles, the scent of lavender, which has a pain-suppressing effect, terpene compounds such as linalool, and phenols such as methyl salicylate.

[0254] The management application sends the set treatment protocol to the controller 20. The controller 20 stores this data in its memory and is ready to start treatment. Next, the system 1 executes the treatment protocol, records data during the treatment, completes the process, and stores the data in the cloud server 82, similar to the above-described Fig. 32. The user may operate the user terminal 5, but it is preferable that the treatment be started by voice or action in order to avoid pain caused by contact stimulation as much as possible.

[0255] To understand the effect of the above green light treatment, sensors built into the bedding can be used to measure body temperature, pulse, heart rate, blood pressure, breathing sounds, etc. From this data, the user's stress level and sleep quality can be estimated and it can be determined whether the treatment is effective. Although measurements can be made using a wearable device, it is preferable to use a device built into the bedding, considering the stress that wearing the device causes to the user. In addition, tests at medical institutions can include interviews about pain levels, measuring the concentrations of serotonin and norepinephrine in the blood and saliva, and recording brain waves using EEG.

[0256] (7-6) Using System 1 to improve health and mood Another use of the system 1 is treatment for improving health and mood. In this case, the system 1 uses light stimuli whose wavelength changes over time. Figure 33 shows an example of an image whose wavelength changes over time. As shown in Fig. 33, an image simulating the change in sunlight outdoors is used as an image in which the wavelength changes over time. As shown in the figure, the wavelength of light in the image changes over time.

[0257] In this usage, in order to display the change from sunrise to sunset outdoors, it is desirable to display the outdoor scenery according to the time of day. The scenery of the area where the user lives can be displayed, but it is also possible to reproduce and display scenery from all over the world, including changes over time. In addition, in system 1, when controlling light stimuli by combining a display and a group of particles, it is desirable for the display to display an image that is compatible with the artificial clouds created by the group of particles, such as a combination of the sea and the sky. Furthermore, the system 1 may employ a simple configuration in which, instead of a video output device, a group of particles simulating clouds is emitted in front of a spherical light simulating the sun.

[0258] (7-6) System 1: Promoting relaxation and sleep by flashing light at long intervals Another way to use System 1 is to use it to emit a light that flashes at long intervals in order to create a relaxing effect. Slowly blinking light has a relaxing effect and is suitable for inducing sleep, so for example in a bedroom, images of night scenes or other patterns could be displayed on a display while blinking to encourage falling asleep. In addition, by flashing the aforementioned green light for pain suppression, it is possible to provide the user with a pain suppression effect due to the green light and a relaxing effect due to the flashing. In either case, it is desirable for the blinking period to be at least 2 seconds.

[0259] (7-7) A system that recommends appropriate measures So far, we have described embodiments that are targeted at the prevention and treatment of specific diseases and ill health, but there are also cases where the user is not clear about "what disease he or she should take measures against." In particular, since there are no subjective symptoms during the prevention stage, it is desirable for the diagnostic device to detect the signs and recommend appropriate treatment. In addition, in order to support a plurality of treatments, the treatment device is also required to be configured to support a plurality of treatments. The following describes a process of estimating an appropriate treatment and recommending it to a user.

[0260] First, the user sets up the application of the testing device (wearable device, sensing device, smartphone, etc.) to send data to the treatment management application. The treatment management application analyzes the user's condition based on the received data and estimates the necessary treatment.

[0261] For example, if behavioral data indicates that a user's cognitive ability is declining, treatment using gamma frequency light and sound stimuli can be recommended.Also, if a user's sleep rhythm is estimated to be disrupted, treatment using blue light in the early morning can be recommended.

[0262] In addition, the user analysis device 40 equipped with the various image sensors described above can grasp the history of the light the user was exposed to throughout the day and estimate the wavelengths of light that are lacking. For example, for a user who rarely goes outside and is exposed to little red light, treatment using red light in the bathroom can be recommended. In addition, medical institution test data can be entered into a treatment management application and used as material for determining appropriate treatment. For example, a person who is found to have the ε4 / ε4 allele of ApoE (a factor related to cholesterol metabolism) from the results of a genetic test has about four times the risk of dementia compared to ε3 / ε3 (neutral type). For this reason, it can be recommended that treatment using gamma frequency light and sound stimulation be performed for a longer period of time than other users.

[0263] (7-8) Configuring devices for multiple procedures The device to be used for the treatment is an LCD display with the following three color LED light sources mounted on the backlight. To ensure the necessary brightness, it is desirable to place the LEDs densely across the entire panel. Blue: Around 480 nm (Applications: dementia treatment, circadian rhythm regulation, etc.) Green: Around 525 nm (Applications: dementia treatment, pain control, etc.) Red: Around 670 nm (Applications: dementia treatment, PBMT, etc.) The above configuration makes it possible to generate light stimuli corresponding to various treatments, thereby providing content with appropriate wavelengths and frequencies according to the user's condition.

[0264] It is also possible to perform multiple treatments simultaneously. For example, by providing gamma frequency light stimulation when waking up, using video content with a lot of blue (such as a blue sky), it is possible to prevent and treat both dementia and SAD. In addition, by providing gamma frequency light stimulation using video content with a high red content (such as a sunset video), it is possible to simultaneously treat dementia, retinal diseases, skin diseases, etc. The video output device may be installed in a specific room or facility, but may also be made portable as a tablet device and installed and used wherever necessary.

[0265] (7-8) Use as a game Images from a display or projector used as a video output device in the system 1, particles emitted from the particle emission device 30, and the like can be used as game content. For example, when performing therapy using light and sound stimuli in the gamma band (25-100 Hz), the aforementioned OFF insertion process is performed on the game's images and sounds, generating images and sounds that alternate between ON and OFF at a regular interval.

[0266] Because image flickering occurs, video-based content such as shooting games, racing games, and action games are preferable over content that involves reading text, such as role-playing games and quiz games. The present invention can also be used as a video for content that combines games and fitness. For example, there is known content in which a player in a game moves forward when the user pedals a bicycle.

[0267] By modifying these contents for dementia treatment, it is possible to carry out dementia treatment through exercise and light and sound stimulation treatment in parallel. In addition, by converting the images in the game into colors with specific wavelengths, such as blue, red, or green light, suitable for treatment, it is possible to perform treatment while playing the game. In addition, devices that generate electrical or ultrasonic stimulation to the skin can be built into the game console.

[0268] (7-9) Use in rooms for yoga, meditation and religious ceremonies System 1 can be used in a room for yoga, meditation, mindfulness, etc. For example, viewing images of natural scenes has been shown to reduce the effort required to practice mindfulness, and it is desirable for the images output by the light stimulation device 10 to mimic natural scenes. In addition, when performing yoga or meditation, it is important that the user is relaxed, and the state of relaxation can be understood by a wearable device such as a smart watch that records the heart rate, etc. Data from these wearable devices may also be acquired as treatment history data.

[0269] System 1 can also be used in rooms where religious ceremonies such as prayers are held. Images of Buddhist statues, religious paintings, temples, shrines, churches, sacred mountains, etc. can be displayed on the LCD display, and mist can be generated in front of the room to create a sense of solemnity and holiness. In addition, there are also existing products such as Buddha statues with LEDs. It is also possible to place a treatment light source on such structures with religious significance and add a group of fine particles such as mist to them and use them as treatment devices.

[0270] <Second embodiment> (8) Application examples of System 1 Next, an application example of the system 1 will be described as a second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

[0271] First, the combination of System 1 and a dementia testing system will be described. As mentioned above, System 1 reduces the burden on the user to continue performing treatment, but by understanding the effects of the treatment from measurements and test results, the user can realize the concrete benefits of the treatment, which increases the incentive to continue using System 1. In addition, highly effective treatment protocols can be identified from test results.

[0272] For example, it is possible to link the implementation log of stimulation treatment with rewards. This will solve the problem of not being able to continue light treatment, which could not be solved by existing systems, by linking the implementation of light treatment with rewards and providing a monetary incentive, making it possible to improve intractable diseases including dementia.

[0273] In addition, by linking with insurance and financial services, monetary benefits such as points that can be used for shopping or loans will be directly linked to the continuation of treatment, increasing the incentive for users to continue treatment. As a result of the above effects, as the number of people undergoing treatment increases, the need for content included in treatment protocols also increases, and the market for treatment content also expands. Content creators also find it easier to invest in content creation, and the quality of content improves. As the quality of content improves, users have an even greater incentive to undergo treatment, which leads to better health, creating a virtuous cycle.

[0274] The content used by System 1 is intended to improve the user's health, so content creators can feel a sense of fulfillment knowing that their work contributes to society. In addition, by evaluating the treatment contents based on the test data, it is possible to select and provide to the user "contents whose improvement effects are supported by objective indicators" by evaluating the treatment contents based on the test results. In addition, the user's sense of trust and security in the treatment is improved. An examination system using such a system 1 will be described in detail.

[0275] (8-1) Business model in which an inspection system using System 1 is used In this inspection system, for example, the system 1 can be used in conjunction with a business model to provide content tailored to user preferences. Here, we will explain the business model and distribution flow in which a specific company provides a platform for various devices that deliver light and sound stimuli, management applications, and testing devices (such as wearable devices) for evaluating the effects of treatment.

[0276] 34 is a diagram showing a business model in which an inspection system using the system 1 is used. In this diagram, the flows of "various data," "things (devices)," and "money" are shown as the flows of merchandise in the business model. As shown in Figure 34, the following players appear in this business model: User: A person who uses System 1 to take necessary measures (mainly general consumers) Treatment / examination device manufacturer: An entity that manufactures System 1, provides it to users, and proposes appropriate processing to users using System 1 (mainly companies that manufacture medical devices) Content maker: A person who generates and provides video data that will be used as content for processing in System 1 (mainly companies such as video production companies, or individuals)

[0277] In this business, the device manufacturer provides the users with each device constituting the system 1 together with a treatment management application. At this time, the device manufacturer may provide the users with individual devices for testing. In return for the provision of each device, the user pays a usage fee to the device manufacturer. In this case, the user may purchase each device or may rent it and pay a usage fee according to usage by subscription.

[0278] The device manufacturer creates a sales platform on the management application where content manufacturers can sell the video and audio content used in the treatment, and collects platform usage fees from the content manufacturers. A content maker provides the treatment content that he / she has created to a sales platform and collects a content usage fee according to the user's usage.

[0279] The user operates the user terminal 5 to select the treatment contents he / she wishes to use from among those registered in the management application in registering a treatment command, and uses the system 1. At this time, the user acquires points according to the frequency of use. In addition, the user may perform a test described later using the system 1. The test result is recorded as a cognitive length measure score.

[0280] The management application started on the user terminal 5 acquires a log of the actions taken by the system 1. Furthermore, when the user performs an inspection using the system 1, the management application acquires the inspection results. Here, the inspection may be performed in exchange for the usage points acquired by the user. In other words, the system may be configured to perform the inspection when the user continuously performs the treatment by the system 1. In this way, the inspection can be used as an incentive for the continuous use of the system 1.

[0281] Device manufacturers obtain usage logs of content selected by users from the data of the management application. By analyzing the content usage logs, a system can be built that recommends content suitable for each user. This benefits both manufacturers and users, as users can efficiently obtain information about content that matches their preferences.

[0282] In addition, the device manufacturer may simultaneously provide a device for testing dementia to monitor the effect of the treatment. For example, the system 1 may build a system for evaluating the cognitive function of the user as the user analysis device 40 to test dementia, as shown below. A system for measuring the user's motor function using motion sensors (accelerometers, gyro sensors, etc.) built into wearable devices and smartphones - Circadian rhythm evaluation system using sleep monitoring devices - A system for evaluating a user's cognitive function by analyzing the user's typing speed on a smartphone

[0283] Although the accuracy of tests of the user's cognitive function using the above-mentioned System 1 is lower than tests at medical institutions, it can be used on a daily basis and is therefore particularly suitable for detecting changes in the early stages of dementia. A monitoring system using the devices that make up System 1 allows the user to continue treatment while checking with concrete data that dementia is not progressing or is improving. In addition, if the measurement results from the testing system indicate a tendency toward a decline in cognitive function, the user can be prompted to undergo testing at a medical institution, preventing delays in the start of treatment.

[0284] (8-2) Business model using insurance and financial systems based on System 1 Next, we will explain how to use and the business model when the system 1 is applied to the insurance business or the financial business. Figure 35 is a diagram showing a business model in which an insurance / financial system using the system 1 is used. In this figure, the same flow of products as in Figure 34 is shown with dashed lines, and their explanation will be omitted. The other players who appear in this business model are as follows: Medical institution: For example, an institution that provides medical treatment for a specific disease such as dementia (assuming a hospital) Insurance companies, financial companies: Those who provide insurance services or loans by assessing the user's physical risk based on information obtained from system 1

[0285] In this business model, users register with a specific insurance or financial system and link it to a treatment management application. Logs of treatments received by users and test results obtained by testing devices are sent to the insurance or financial service application and reflected in the evaluation of insurance premiums, loans, etc.

[0286] In addition, the history of medical examinations at medical institutions can also be subject to evaluation. For example, tests such as fMRI brain imaging, amyloid PET imaging, blood tests (amyloid peptide amount, etc.), genetic tests (APoE genotype, etc.), cerebrospinal fluid tests (CSF tau, amyloid beta, ferritin, iron-related proteins), electroencephalography (EEG), cognitive ability tests, and retinal imaging can be used. The test results are sent by the user to insurance and financial service applications.

[0287] The above data and diagnostic results will be evaluated, for example, from the following perspectives, and users will be provided with benefits such as points, discounts, and preferential treatment when applying for loans based on the evaluation score. The treatment is performed at a certain frequency and for a certain period of time (total treatment time in various places such as the bathroom, toilet, bedroom, etc.) - Regularly undergoing medical checkups - Test results must meet or improve a certain standard.

[0288] For example, a user who undergoes daily gamma frequency stimulation treatments and whose cognitive performance and amyloid-β accumulation levels are within normal ranges may be deemed to have a high likelihood of maintaining cognitive ability over the long term, and may be eligible for rewards such as lower insurance premiums or lower interest rates on loans.

[0289] In addition, by displaying advertisements for medical institutions that perform dementia tests on the screens of management applications and insurance / financial system management applications, it is possible to provide information on tests that meet the needs of users. This also leads to an increase in users for testing companies, which can be expected to increase revenue, creating a system that is mutually beneficial. In addition, as test data is accumulated, effective content for maintaining and improving cognitive function becomes clearer, so the more users use the app, the more effectively they can prevent dementia.

[0290] The above system may be applied not only to gamma stimulation therapy, but also to the prevention and improvement of other health conditions that are expected to be improved by the use of System 1, such as seasonal affective disorder, winter depression, jet lag, retinal disease, pain suppression, and wellness improvement.

[0291] (8-3) When insurance companies provide a platform for dementia treatment and testing As a more specific example, we will explain an ICT system that combines System 1 with insurance services. In a typical insurance service, the user (or the user's company) pays a premium to the insurer (such as an insurance company), and the insurer pays for medical fees when the user visits a medical institution and a portion of the compensation for time off work due to illness. There are also cases where the insurer pays medical expenses to the medical institution. Therefore, if the health condition of the user, including the cognitive function, is improved by using the system 1, the insurer can reduce the burden and increase the profit, and therefore it is possible to lower the insurance premium. Specific examples of insurance services are described below.

[0292] Fig. 36 is a diagram showing a business model in which an insurance company provides a platform for stimulation treatment and testing for dementia. In this figure, parts similar to those in Figs. 34 and 35 described above are indicated by dashed lines, and their explanations are omitted. As shown in Fig. 36, the user pays the insurer a service fee, and the insurer provides the user with devices (stimulation treatment device, inspection device) purchased from a device manufacturer and a management application (hereinafter referred to as insurance application). The devices may be purchased by the user or the company to which the user belongs.

[0293] A user uses the insurance application on a smartphone or other terminal and uses the stimulation treatment device and the inspection device according to the application's guide. It is desirable that the insurance application be a web application that can be accessed from a web browser so that it can be accessed from various terminals.

[0294] The insurance application evaluates the user's dementia prevention level based on the user's treatment log and test results, and provides the user with rewards such as discounts on insurance premiums based on the evaluation results. In addition, the application recommends the content of treatments that the user should take in the future (such as treatment content) based on the evaluation of the content.

[0295] Users who take appropriate measures against dementia will receive more rewards, providing an incentive for them to continue their treatment. In addition, users will receive recommendations on what measures to take in the future, allowing them to take more effective measures, and the more the user uses the service, the better their health will improve.

[0296] In addition, since the effectiveness of treatment can be objectively evaluated from the log of the test results, it is possible to select highly effective content, and content makers who create high-quality content can sell more content. The insurance system 2 that performs such processing is described below.

[0297] (8-3-1) Configuration of insurance management server 90 FIG. 37 is a diagram showing the state of data communication at the start of use of the insurance system 2 using the system 1. As shown in FIG. As shown in FIG. 37, the insurance system 2 includes an insurance management server 90 (hereinafter simply referred to as the management server 90) that is used together with the system 1. The management server 90 includes a processor 91 , a memory 92 , a storage 93 , a communication IF 94 , and an input / output IF 95 .

[0298] The processor 91 is hardware for executing an instruction set written in a program stored in the memory 99, and is composed of an arithmetic unit, a register, peripheral circuits, and the like. The processor executes a program related to the insurance application to perform, for example, the following processes. - Log of actions taken by System 1 Obtaining test results Analysis of action logs and test results (evaluation of users and quality content) -Recommendations of high-quality content These processes will be described in detail later.

[0299] The memory 92 is for temporarily storing programs and data to be processed by the programs, and is a volatile memory such as a DRAM (Dynamic Random Access Memory). The programs include, for example, the following programs: ·OS (Operating System) programs · Insurance application programs Web browser program that processes information

[0300] The storage 93 is a storage device for saving data, such as a flash memory, a hard disc drive (HDD), or a solid state drive (SSD).

[0301] The communication IF 94 is an interface for inputting and outputting signals so that the system 1 can communicate with an external device. Specifically, the communication IF 94 desirably uses a module compatible with a general-purpose communication standard.

[0302] The input / output IF 95 functions as an interface with an input device (e.g., a pointing device such as a mouse, a keyboard) for receiving input operations from the user, and an output device (a display, a speaker 63, etc.) for presenting information to the user.

[0303] Next, a description will be given of the functional configuration of the management server 90. FIG. The management server 90 functions as a communication unit 901 , a storage unit 902 , and a control unit 903 . The communication unit 901 performs processing for the management server 90 to communicate with external devices.

[0304] The storage unit 902 stores data and programs used by the management server 90. The storage unit 202 stores user information, usage logs, scores, inspection results, evaluation rules, and processing contents.

[0305] User information is personal information of a user stored for each user ID, and includes the user's name, age, sex, place of residence, occupation, etc. The user information may include the following information: Device information of the user terminal 5 used by the user The contents of the user's insurance contract · Functional goals of the body that you want to achieve by using System 1 System 1 Favorite Treatment Content - Rating score given to the user

[0306] The usage log is information indicating the history of actions taken by a user using the system 1. The usage log includes at least the following: ·Date and time of use User ID of the user who used the service - Contents of the treatment protocol (information on treatment contents, output intensity, output time, etc.)

[0307] The test result is information that associates the test result by the test device with the user ID. The test results may include the results of a medical examination entered by a user that does not involve a testing device.

[0308] The evaluation rules are information that prescribes the criteria for evaluation in the insurance system 2. The evaluation rules include at least the following information. - Evaluation criteria for the primary score given according to the frequency of use by the user Evaluation criteria for weighting factors given according to test results - Regulations regarding rewards according to evaluation scores · Criteria for evaluating quality content The evaluation score is calculated by multiplying the primary score by a weighting coefficient.

[0309] The content data is content data as material before being converted into content for treatment. The content data may be stored in association with the content score.

[0310] The control unit 203 performs functions as a transmission / reception unit 9031, a log acquisition module 9032, a test result acquisition module 9033, an evaluation module 9034, and a recommendation module 9035 by the processor 21 of the management server 90 executing the insurance application.

[0311] The transmitting / receiving unit 2031 controls the process in which the management server 90 transmits a signal to an external device in accordance with a communication protocol, and controls the process in which the management server 90 receives a signal from an external device in accordance with the communication protocol.

[0312] The log acquisition module 9032 acquires a log of the treatment by the system 1 from an application of the user terminal 5. The log acquisition module 9032 stores the acquired log in the storage unit 902. That is, the log acquisition module 9032 records the treatment time and the treatment frequency in the storage unit 902 as the results of the light treatment.

[0313] The test result acquisition module 9033 acquires the test results of the user from the test device. The test result acquisition module 9033 stores the acquired test results in the storage unit 902. That is, the test result acquisition module 9033 acquires the test results regarding the cognitive ability of the user.

[0314] The evaluation module 9034 evaluates the user and assigns an evaluation score based on the user's usage history of the system 1 and the test results in accordance with the processing described below. The evaluation module 9034 stores the evaluation results in the storage unit 202. That is, the evaluation module 9034 evaluates the user based on the recorded light treatment results and the progress of the user's cognitive ability confirmed by the light treatment results and the test results. The evaluation module 9034 also evaluates the treatment contents by comparing the test results of a plurality of users, and identifies superior contents. The evaluation module 9034 stores the evaluation results in the storage unit 202.

[0315] The recommendation module 9035 recommends excellent content to the user based on the evaluation result of the content to be processed by the evaluation module 9034.

[0316] Next, the processing by the insurance system 2 will be described. The processing by the insurance system 2 is divided into the following steps: Step 1: Start using the insurance application and register your device Step 2: Obtaining treatment logs and test results Step 3: Analyze the log of actions and evaluate the user's dementia prevention level · Step 4: Recommendations to users based on content ratings Each of these steps is described below.

[0317] (8-3-2) Step 1: Start using the insurance application and register your device The user registers to use the insurance application using the user terminal 5. The user inputs user information such as a user ID (for example, an email address), password, age, and gender using an input device such as a keyboard or a touch panel. 37, the input user information is transmitted from the user terminal 5 to a management server 90 that manages insurance applications via a network. The transmitted information is stored in a user database in memory via a communication module of the management server 90.

[0318] Next, the user registers the treatment device and the inspection device to be used in the insurance application. Address information of the device information is transmitted from the communication module of the device to the communication module of the user terminal 5 by short-range wireless communication or via a wireless communication network, and is stored in the memory of the user terminal 5. The stored device information is transmitted from the user terminal 5 to the management server 90 via a network such as the Internet, and is stored in the storage unit 902. Through the above process, the device information of the user terminal 5 linked to the user ID is stored as user information in the storage unit 902 of the management server 90.

[0319] (8-3-3) Step 2: Obtaining treatment logs and test results FIG. 39 is a diagram showing the state of data communication when the insurance system 2 using the system 1 is used. First, in the insurance system 2, the system 1 executes a procedure and obtains a log of the procedure. The content data used in the process is generated in advance by a producer such as a content maker or creator. The content data, together with text data such as the title, the producer's name, and the category, is transmitted to the communication module of the management server 90 via the network and stored in the storage unit 902.

[0320] The available content is displayed on a Graphical User Interface (GUI) of the insurance application. Furthermore, the user can operate an insurance application running on the user terminal 5 to search for content to be output when using the system 1 by category or keyword.

[0321] For example, a user sends a request via the network from a search menu of an insurance application. The processor of the management server 90 compares the contents of the request with the text data in the storage unit 902, identifies content that matches the request, sends it via the network, and displays it on the GUI of the insurance application. The user selects the content that suits his / her preferences and other settings (light intensity, treatment time, etc.) and determines the treatment protocol.

[0322] The insurance application transmits the treatment protocol selected by the user from the user terminal 5 to the controller 20 of the system 1 by wireless communication, and the user receives treatment according to the specified protocol. The log acquisition module 9032 of the management server 90 acquires the log of the action. Specifically, the log of the action is transmitted from each device to the user terminal 5 by wireless communication and stored in the memory of the user terminal 5. The stored log of the action is transmitted from the user terminal 5 to the management server 90 via a network such as the Internet. The log acquisition module 9032 stores the transmitted log of the action in the storage unit 902 as a usage log of the user.

[0323] Next, acquisition of the test results from the test device will be described. The user uses the test device to test the cognitive function. Here, the test may be performed using a test device constituting the user analysis device 40 of the system 1, or a separate test device may be used. Specific test devices and test contents include, for example, the following contents.

[0324] First, examples of testing using a smartphone, tablet or PC include the following: -Typing speed from input device Dementia test app score -Subjective scores for sleep quality, mood, etc. based on questionnaires -Evaluating exercise volume based on changes in smartphone location information

[0325] Examples of testing using wearable devices include the following: -Evaluation of user's exercise volume -Evaluation of circadian rhythm phase using user's biological information Sleep quality assessment (assessed based on duration and frequency of nighttime activity)

[0326] Examples of tests using sleep monitoring devices include the following: -Evaluation of circadian rhythm phase using user's biological information Sleep quality assessment (assessed based on duration and frequency of nighttime activity)

[0327] In addition, examples of the inspection data from the inspection agency (manually entered by the user from the insurance application) include the following: fMRI imaging Amyloid PET imaging ·Blood tests (amyloid peptide levels, etc.) Genetic testing (APoE genotype, etc.) Cerebrospinal fluid test (CSF tau, amyloid beta, ferritin, iron-related proteins) Electroencephalography (EEG) Cognitive ability test results Retinal imaging In addition, tests other than these may be performed.

[0328] The test data obtained from each of the above tests is transmitted from each test device to the user terminal 5 and stored in the memory of the user terminal 5. The stored treatment log is transmitted from the user terminal 5 to the management server 90 via the network. The test result acquisition module 9033 acquires the transmitted test results and stores them in the memory unit 902.

[0329] (8-3-4) Step 3: Analyzing the log of actions and evaluating the user's dementia prevention level FIG. 40 is a diagram showing the processing performed by the evaluation module 9034 of the management server 90. As shown in FIG. As shown in FIG. 40, the evaluation module 9034 of the management server 90 receives an evaluation instruction (step S301). Specifically, the evaluation instruction input from the insurance application is accepted at preset time intervals (for example, every other day).

[0330] Next, the evaluation module 9034 queries the user information to identify the target user (step S302). Specifically, the evaluation module 9034 refers to the user information for the user to be evaluated, identifies the user ID from the device information, and identifies the usage log and the inspection result linked to the user ID.

[0331] Next, the evaluation module 9034 assigns a primary score according to the frequency of treatment (step S303). Specifically, the evaluation module 9034 refers to the log of the actions and the evaluation criteria stored in the storage unit 902, and calculates a primary score according to the frequency and time of the actions. Fig. 41 is a diagram showing an example of evaluation criteria related to the primary score given according to the frequency of use by the user.

[0332] As shown in FIG. 41, a primary score according to the frequency of treatment is set as an evaluation rule. In the illustrated example, for example, the evaluation rules are set such that a user who performs a procedure 5 or more times a week is given 30 points, a user who performs a procedure 2 to 4 times a week is given 20 points, and a user who performs a procedure 1 time a week or less is given 5 points. Note that the evaluation criteria for the primary score according to the frequency of performing the procedure can be changed arbitrarily.

[0333] After step S303, the evaluation module 9034 refers to the inspection data (step S304). Specifically, the evaluation module 9034 uses the user ID to identify the test results stored in the storage unit 902 for the user to be evaluated.

[0334] After step S304, the evaluation module 9034 calculates weights according to the inspection data (step S305). Specifically, the evaluation module 9034 evaluates the test results based on the target range of the test score. That is, the evaluation module 9034 evaluates the transition of the user's cognitive ability by comparing a preset reference value with a value indicated by the test result. Here, the following patterns are included as cases in which the transition of cognitive ability is evaluated. - When cognitive ability improves through the use of System 1 Cognitive abilities are maintained by the use of System 1 - When it is recognized that the decline in cognitive ability has been suppressed more than expected by utilizing System 1 The target range of test scores can be set based on the average score data of healthy individuals (those who do not have mild cognitive impairment or dementia) and those with cognitive impairment. For example, the following standards are known for typing speed: Healthy subjects had an average of 115 keystrokes / min (95% confidence interval ±11). Those with symptoms of cognitive impairment had an average of 87 keystrokes / min (95% confidence interval ±10). Taking this into consideration, the target range can be set at 115±11.

[0335] The data of the target range is created in advance by an insurance company or the like, and is stored as an evaluation criterion in the storage unit 902. Fig. 42 is a diagram showing an example of an evaluation criterion related to a weighting coefficient assigned according to the test result. In the example of FIG. 42, the weighting coefficients (Y values) are set as follows: - 3 users with test scores above the target range · 2 users within the target range - 1 user below the target range 0.5 if no test was performed In this example, by giving a higher value to users who take the test than to users who do not, even if the initial score based on frequency of use is low, the evaluation score can be increased by taking the test, giving users an incentive to take the test.

[0336] Then, the evaluation module 9034 compares the test result of the user to be evaluated with the target range data stored as the evaluation criterion, and calculates a weighting (Y value) from the comparison between the test result and the target range. The target range may be set for each user. In this case, the user ID is linked to the evaluation rule stored in the storage unit 902.

[0337] After step S306, the evaluation module 9034 determines a reward for the user (step S306). Specifically, the evaluation module 9034 calculates a value obtained by multiplying the X value and the Y value as a score indicating the dementia countermeasure level, and determines a reward to be provided to the user based on the calculated value. Fig. 43 is a diagram showing an example of a provision regarding the content of the reward according to the evaluation score.

[0338] In the example shown in Fig. 43, a discount on insurance premiums is set as the reward. As shown in the figure, the higher the evaluation score of a user, the higher the discount rate, and the more benefits the user can obtain. The determined reward is stored in the storage unit 902 in association with the user information.

[0339] After step S306, the evaluation module 9034 notifies the user of the content of the reward (step S308). Specifically, the evaluation module 9034 transmits information regarding the content of the reward to the user terminal 5 via the network. The user terminal 5 displays the information regarding the content of the reward on the GUI of the launched insurance application, thereby presenting to the user that the reward will be given. This completes the processing by the evaluation module 9034.

[0340] Next, the process of determining remuneration for corporate services will be described. FIG. 44 is a diagram showing a process for providing a reward to a corporation. As shown in Figure 44, when this system is provided as a service for corporations, the insurance premium is paid by the company to which the user belongs, not by the user. In this case, the remuneration for the corporation is determined, for example, by the average or median value of the evaluation index of all users belonging to the corporation. The above process is carried out at regular intervals designated by the service provider, such as weekly, monthly, or yearly, and data is accumulated.

[0341] Specifically, first, the evaluation module 9034 calls up data of users who belong to the target company (step S401). Specifically, the evaluation module 9034 uses the company ID of the target company to extract corresponding users from the user DB, and identifies the treatment log and test result data for each user.

[0342] After step S401, the evaluation module 9034 calculates the average or median of the evaluation indexes of the users (step S402). After step S402, the evaluation module 9034 determines a reward according to the calculated value (step S403).

[0343] After step S403, the evaluation module 9034 notifies the relevant company of the details of the remuneration (step S404). Specifically, the evaluation module 9034 transmits information regarding the content of the reward to the computer system of the corporation being evaluated. This completes the process of determining remuneration for corporate services.

[0344] (8-3-5)Step 4: Recommendations to users based on content evaluations Furthermore, the insurance system 2 can make recommendations to users based on the evaluation of the content. That is, the insurance system 2 evaluates and recommends treatment content based on comparative analysis for each user. The recommendation module 9035 performs comparative analysis for each user based on the accumulated data. First, the recommendation module 9035 reads the data in the user database, and extracts "users whose values ​​are continuously improving" or "users who always achieve high values" from the trend of Y values ​​(weighting based on the test results) for a certain period (e.g., one month). In other words, the recommendation module 9035 extracts a group of users who show a favorable tendency in the transition of cognitive ability in the test results, and identifies video content that is used frequently by the extracted group of users. Here, the group of users who show a favorable tendency in the transition of cognitive ability includes the following: -Users whose cognitive abilities improved through the use of System 1 -Users whose cognitive abilities were maintained by using System 1 - A group of users whose cognitive decline was less than expected due to the use of System 1

[0345] FIG. 45 is a diagram showing an example of the evaluation of excellent content. As shown in FIG. 45, the score of each piece of content can be calculated based on the cumulative number of times it is used, as follows: ·Content α: 2+4=6 · Content β: 10 + 10 = 20 · Content γ: 5+5=10

[0346] Then, the evaluation module 9034 calculates the treatment content used by the extracted user (good user) over a specified period (e.g., three months) and the number of times it was used, and identifies the content that the good user tends to use frequently. As a specific calculation method, for example, the number of times good users use the content is calculated as an evaluation score for the content, and the evaluation score for the content is found by summing up the values ​​calculated for all good users.

[0347] Here, content that is repeatedly used by good users is considered to be high quality content because it is likely to satisfy both the "cognitive ability improvement effect" and "desirability." Content evaluation is performed repeatedly, and the content score is constantly updated.

[0348] Next, when the user opens a screen for setting a treatment protocol or searches for content, the recommendation module 9035 of the management server 90 transmits a command to call up the content to be displayed to the management server 90 via the network. The recommendation module 9035 refers to the score of the content, and transmits the content in order of the highest score. The submitted content is displayed on the insurance application as "recommended content" or "top search results." Through the above process, users can easily select high-quality content and receive more favorable and effective treatment.

[0349] (9) Other modifications The configuration of the system 1 can be changed as appropriate. For example, in each of the above embodiments, the system 1 is shown to include the light stimulation device 10 having the light source 11 and the image display unit 12, and the particle group emitting device 30, but this is not limited thereto. The system 1 may include the light source 11 and the particle group emitting device 30 without including the image display unit 12. This is because the light stimulation output from the light source 11 is scattered by the particle group, and can be input to the user as a light stimulation with an appropriately weakened intensity.

[0350] That is, in the system 1, the image display unit 12 and the particle group emitting device 30 have a common function in that they soften the treatment light emitted from the light source 11. For this reason, only one of the image display unit 12 and the particle group emitting device 30 may be provided, or they may be interchangeable.

[0351] Furthermore, the system 1 may not include at least any of the user analysis device 40, the voice recognition device 50, the sound stimulation device 60, and the skin stimulation device 70. In this case, the convenience of each device is reduced, but treatment can be performed using the light stimulation device 10 and the fine particle group emission device 30.

[0352] Furthermore, the blinking of the light source 11 in the system 1 does not necessarily mean repeatedly turning on (ON) and off (OFF). In other words, blinking refers to repeated increases and decreases in illuminance of light with wavelengths in the visible light region, and includes a state in which the illuminance changes according to a predetermined frequency while the light source is always on (ON). This is because a change in illuminance can input a visual stimulus to the user. In other words, the light source 11 only needs to alternate between high and low illuminance states, so it is not necessary to completely turn off the light source 11 at a low timing.

[0353] In addition, the frequency of the output current waveform of general LED lighting is required to be 100 Hz or more to prevent issues such as light flicker. In contrast, the light source 11 of the system 1 preferably has a blinking frequency of less than 100 Hz (a period of more than 10 msec) in order to utilize the effect obtained from the visual stimulation of light that blinks at a low frequency.

[0354] FIG. 46 is a diagram showing an example of a periodic change in illuminance in another modified example of the light source 11. In FIG. The light source 11 of the system 1 may vary its illuminance, for example, according to the following waveform: Figure 46A: Illuminance change along a square wave Figure 46B: Illuminance change along a sine wave Figure 46C: Illuminance change along a triangular wave Figure 46D: The frequency of the pulses changes, resulting in periodic fluctuations in the average illuminance.

[0355] If the illuminance is repeatedly increased and decreased at a constant cycle T, a frequency spectrum will be created by decomposing the waveform through a Fourier transform into sine and cosine waves with constant frequencies, and the maximum peak will be obtained at a frequency of f = 1 / T. For example, if the cycle is 25 msec, the maximum peak will be obtained at a frequency of 40 Hz. In other words, as mentioned above, the blinking frequency in System 1 refers to the frequency at which the maximum peak is obtained in the frequency spectrum obtained by the Fourier transform of the waveform of the change in illuminance over time.

[0356] FIG. 47 is a diagram showing another modified example of the light source 11. In FIG. As shown in Fig. 47, the light source 11, whose illuminance changes, is used together with an illuminance controller 13, which controls the illuminance. The illuminance controller 13 controls the voltage or current input to the light source 11 from an energy source 14, such as a power source, and can change the illuminance of the light source 11 in accordance with the above-mentioned manner of illuminance change.
