Description

Technical Field

[0001] This utility model relates to the field of wearable electronic device technology, and more specifically, to a phototherapy eye mask. Background Technology

[0002] A light therapy eye mask is a wearable electronic device that uses light of specific wavelengths and intensities to simulate the effects of natural light on the body's circadian rhythm, promoting melatonin secretion and thus improving sleep. Specifically, the light therapy eye mask uses a light source to provide precisely controlled light that acts on the retina around the eyes, influencing the brain's central nervous system through the visual pathway, adjusting the circadian rhythm, and improving sleep quality. As a non-drug, non-invasive sleep management tool, it is suitable for individuals who need to improve their sleep in daily life.

[0003] Currently, phototherapy eye masks primarily use a combination of heating, sound, and light to aid sleep. Specifically, they guide breathing through vibration and light, and then use a heating module to specifically heat acupoints around the eyes to meet the sleep needs of people with insomnia. However, existing phototherapy eye masks only improve sleep disorders and cannot regulate emotions. Therefore, if a user is in a bad mood before or during sleep, the eye mask will be ineffective, leading to difficulty falling asleep or interrupted sleep due to negative emotions.

[0004] Therefore, there is an urgent need for a light therapy eye mask that can both regulate emotions and improve sleep. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a phototherapy eye mask that can more accurately determine and adjust the user's emotional state, and can also help the user sleep when they are in a good mood, thereby improving the user's sleep experience.

[0006] This utility model provides a phototherapy eye mask, comprising an eye mask body layer, a hardware layer, a filter layer, and a support layer arranged sequentially from the outside to the inside. The hardware layer includes a main control device, a human body parameter acquisition device, a parameter processing device, and an adjustable light emission color, all of which are communicatively connected to the main control device. The parameter processing device is used to determine the emotional state based on the human body parameters, and the main control device is used to control the light emission device to display the corresponding color based on the determination result.

The EEG ground electrode, the EEG acquisition electrode, the EEG reference electrode, the skin electrical signal acquisition electrode, and the skin electrical reference electrode do not contact the filter layer and the support layer, but directly contact the human skin.

[0008] Preferably, in the above-mentioned phototherapy eye mask, the human body parameter acquisition device further includes a heart rate and blood oxygen acquisition component, and the heart rate and blood oxygen acquisition component is disposed on the hardware layer at a position corresponding to the position of the human temple after wearing the phototherapy eye mask.

[0010] Preferably, the phototherapy eye mask further includes a wireless communication device that is communicatively connected to the main control device. The wireless communication device is used to communicate with a user terminal to synchronize the data in the phototherapy eye mask to the user terminal.

[0011] Preferably, the above-mentioned phototherapy eye mask also includes a display device that is communicatively connected to the main control device. The display device is disposed on the outer side of the eye mask body layer and is used to display human body parameters, emotional state, and sleep state.

[0012] Preferably, the above-mentioned phototherapy eye mask also includes a power supply device that is electrically connected to the main control device, the human body parameter acquisition device, the parameter processing device and the lighting device simultaneously. The power supply device is arranged adjacent to the lighting device and has a charging port located on the hardware layer at a position corresponding to the adjacent part of the human face after wearing the phototherapy eye mask.

[0013] Preferably, in the above-mentioned phototherapy eye mask, the support layer is a silicone support layer, and a forehead protector and a nose pad are provided on it. The forehead protector is positioned at a position corresponding to the forehead of the human body after wearing the phototherapy eye mask, and the nose pad is positioned at a position corresponding to the upper part of the nose of the human body after wearing the phototherapy eye mask. The support layer also has through holes corresponding to the positions of the EEG grounding electrode, the EEG acquisition electrode, the EEG reference electrode, the skin conductance acquisition electrode, and the skin conductance reference electrode.

[0014] Preferably, in the above-mentioned phototherapy eye mask, the lighting device consists of two LED lights that can switch between orange light and full-spectrum white light, and are respectively disposed on the hardware layer at positions corresponding to the human eyes after wearing the phototherapy eye mask;

[0015] It also includes a timing device and a switching device that are communicatively connected to the main control device.

[0016] Preferably, in the above-mentioned phototherapy eye mask, the eye mask body layer includes a light-shielding plate and eye mask straps located on both sides of the light-shielding plate, and the two eye mask straps have detachable connecting parts, which are Velcro or buckles.

[0017] As can be seen from the above technical solution, the phototherapy eye mask provided by this utility model includes a main control device and a human parameter acquisition device, a parameter processing device, and an adjustable light emission color, all of which are communicatively connected to the main control device. The parameter processing device is used to determine the emotional state based on human parameters, and the main control device is used to control the light emission color to be displayed according to the determination result. Thus, when the main control device knows that the user's emotion needs adjustment, it switches the light emission color to one that can regulate the user's emotion; when it knows that the user does not need to adjust their emotion, it switches the light emission color to another that can promote sleep. Therefore, the phototherapy eye mask can not only more accurately determine and adjust the user's emotional state, but also play a role in promoting sleep when the user is in a good mood, thereby improving the user's sleep experience.

[0022] The core of this invention is to provide a phototherapy eye mask that can more accurately judge and adjust the user's emotional state, and can also help the user sleep when the user is in a good mood, thereby improving the user's sleep experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] An embodiment of the phototherapy eye mask provided by this utility model is as follows: Figure 1 and Figure 2 As shown, Figure 1 An exploded view of an embodiment of a phototherapy eye mask provided by this utility model. Figure 2This is a schematic diagram of the control module of an embodiment of a phototherapy eye mask provided by this utility model. The phototherapy eye mask may include, from the outside to the inside, an eye mask body layer 1, a hardware layer 2, a light filter layer 3, and a support layer 4. That is, when a user wears the phototherapy eye mask, the support layer 4 is in direct contact with the human face and can be made of silicone fabric that conforms to the human face to ensure good wearing comfort. A certain distance is maintained between the eyes and the eye mask at the eye socket area. Outwardly, there is a light filter layer 3 for filtering out strong ultraviolet light and harmful light to avoid damage to the human eyes, a hardware layer 2 that can realize multiple functions, and an eye mask body layer 1 for blocking natural light. Layer 1, located on the outermost layer, is the main body of the eye mask that is directly visible from the outside. It is essentially the most basic component of an eye mask, used to block natural light and ensure the accuracy and stability of light color adjustment. This embodiment adds other layers on top of this to achieve more functions. Specifically, hardware layer 2 may include a main control device 21, a human parameter acquisition device 22, a parameter processing device 23, and an adjustable light emission color lighting device 24, all of which are communicatively connected to the main control device 21. The parameter processing device 23 is used to determine the emotional state based on human parameters, and the main control device 21 is used to control the lighting device 24 to display the corresponding color based on the determination result. Specifically, this human body parameter acquisition device 22 can collect various physiological parameters of the human body that can be used to determine the current mood. The appropriate number and type of sensors can be selected according to actual needs. The parameter processing device 23 can process the collected human body parameters, determine the user's emotional state based on these parameters, and send the emotional state determination result to the main control device 21. When the determined emotional state is good, the main control device 21 can directly adjust the light emission color of the lighting device 24 to a color that promotes sleep. Conversely, when the determined emotional state is bad, promoting sleep is ineffective, so the main control device 21 can adjust the light emission color of the lighting device 24 to a color that promotes sleep. The light source emits a different color for the user's mood until the mood is adjusted. Once the user's mood is adjusted, the main control device 21 receives a result indicating a good mood from the parameter processing device 23. At this point, the light emission color of the lighting device 24 can be adjusted to a color that promotes sleep, allowing the user to sleep better while in a good mood. It is evident that the lighting device 24 used in the phototherapy eye mask provided in this embodiment can both adjust the user's mood under the control of the main control device 21 and promote sleep. This demonstrates that it takes into account various situations before the user falls asleep, ensuring that appropriate processing can be carried out for various situations, thereby improving the user's sleep. The main control device 21 may, but is not limited to, use an STM32 main chip.

[0025] As can be seen from the above technical solution, in the embodiment of the phototherapy eye mask provided by this utility model, the hardware layer includes a main control device and a human parameter acquisition device, a parameter processing device, and an adjustable light emission color, all of which are communicatively connected to the main control device. The parameter processing device is used to determine the emotional state based on the human parameters, and the main control device is used to control the light emission device to display the corresponding color based on the determination result. Thus, when the main control device knows that the user's emotion needs adjustment, it switches the light emission device to a color that can regulate the user's emotion; when it knows that the user does not need to adjust their emotion, it switches the light emission device to another color that can promote sleep. Therefore, it can be seen that the phototherapy eye mask can not only more accurately determine and adjust the user's emotional state, but also play a role in promoting sleep when the user is in a good mood, thereby improving the user's sleep experience.

[0026] In a specific embodiment of the aforementioned phototherapy eye mask, refer to Figure 1 The aforementioned human body parameter acquisition device 22 may include an electroencephalogram (EEG) signal acquisition component 221 and an electrodermal (ED) signal acquisition component 222. The EEG signal acquisition component 221 includes an EEG ground electrode 2211, an EEG acquisition electrode 2212, and an EEG reference electrode 2213. The EEG signal acquisition component 222 includes an EEG acquisition electrode 2221 and an EEG reference electrode 2222. The EEG ground electrode 2211, EEG acquisition electrode 2212, EEG reference electrode 2213, EEG acquisition electrode 2221, and EEG reference electrode 2222 do not contact the filter layer 3 and the support layer 4, but directly contact the human skin. It should be noted that this embodiment combines the acquired EEG signals with the EEG signals, thus ensuring more accurate judgment of emotions.

[0027] In further embodiments, reference continues to be made to Figure 1 The human body parameter acquisition device 22 may also include a heart rate and blood oxygen acquisition component 223, and this heart rate and blood oxygen acquisition component 223 may be disposed on the hardware layer 2 at a position corresponding to the position of the temple of the human body after wearing the phototherapy eye mask. Figure 1 As can be seen, a heart rate and blood oxygen acquisition component 223 can be set on each side, and both can simultaneously collect the user's heart rate and blood oxygen information. This can ensure more accurate acquisition. Combining heart rate and blood oxygen information with EEG and EEG signals for analysis can ensure more accurate judgment of emotions, because a bad emotional state will be reflected in parameters such as heart rate and blood oxygen. Therefore, combining these two parameters can better perform emotion analysis.

[0028] In a further embodiment, reference continues to be made to... Figure 1The aforementioned human body parameter acquisition device 22 may further include a body temperature acquisition component 224, which can be positioned on the hardware layer 2 at a location corresponding to the area where the upper part of the nose is pressed after the person wears the phototherapy goggles. It should be noted that this position ensures stable contact between the phototherapy goggles and the human body, preventing significant movement during wear. Therefore, this body temperature acquisition component improves the accuracy of temperature measurement. Only one body temperature acquisition component is needed here; however, in special circumstances, another body temperature acquisition component can be symmetrically arranged. This is not a limitation.

[0029] For further details, please refer to... Figure 1 The aforementioned phototherapy eye mask may also include a wireless communication device 25 that is communicatively connected to the main control device 21. This wireless communication device 25 can be used to communicate with a user terminal to synchronize data from the phototherapy eye mask to the user terminal. Specifically, this wireless communication device is preferably a Bluetooth device. Through such a Bluetooth device, data can be quickly synchronized to a user terminal such as a mobile phone or tablet, allowing users or relevant personnel such as doctors and nurses to quickly understand various physiological parameters, sleep patterns, and emotional states. Data can be summarized to draw relevant conclusions and score sleep or mood to aid in better subsequent mood and sleep regulation. Of course, other types of wireless communication devices, such as Zigbee modules or Wi-Fi modules, can also be selected according to actual needs; there are no limitations here.

[0030] In a further embodiment, reference continues to be made to... Figure 1 The phototherapy eye mask may also include a display device 26 communicatively connected to the main control device 21. This display device 26 can be disposed on the outer surface of the eye mask body layer 1 and is used to display human body parameters, emotional state, and sleep state. Figure 1 As can be seen, an opening is made on the eye mask body layer 1 at the position corresponding to the display device 26, allowing the display device 26 to be exposed for viewing by relevant personnel. This embodiment is applicable to scenarios such as users receiving treatment in hospitals. For example, when a user is lying in a hospital bed receiving treatment for a sleep disorder, this display device allows doctors or nurses to know at any time whether the user is currently asleep or in a process of emotional regulation, thus facilitating the recording of relevant information to assist in treatment. Moreover, the human body parameters displayed by this device can also assist in the treatment of the condition, allowing doctors or nurses to understand at any time whether the user has improved and whether a healthy sleep state has been achieved.

[0031] Based on the above-described embodiments of the phototherapy eye mask, continue to refer to... Figure 1The device may further include a power supply device 27 that is simultaneously electrically connected to the main control device 21, the human body parameter acquisition device 22, the parameter processing device 23, and the lighting device 24. This power supply device 27 can be arranged adjacent to the lighting device 24, and it has a charging port 271 located on the hardware layer 2 at a position corresponding to the cheek of the person wearing the phototherapy goggles. Specifically, the power supply device can be, but is not limited to, a lithium battery; other types of batteries, such as alkaline batteries, can also be used. The charging port allows for convenient charging, ensuring long-term use. This charging port can be paired with a power bank for easy portability, allowing for charging whenever the battery is low.

[0032] For further details, please refer to... Figure 1 The aforementioned support layer 4 is preferably a silicone support layer, on which a forehead protector 41 and a nose pad 42 are provided. The forehead protector 41 is positioned corresponding to the forehead of the person wearing the phototherapy eye mask, thus achieving a certain skin care purpose. It can be detachable, and a new forehead protector can be replaced each time the phototherapy eye mask is used. The nose pad 42 is positioned corresponding to the upper part of the nose of the person wearing the phototherapy eye mask, which prevents the nose from being compressed by the eye mask, thereby further improving the user experience. In addition, the support layer 4 may also include an eye socket placement area 43 to maintain a certain distance between the eyes and the phototherapy eye mask, so that the light can have a certain path to illuminate all parts of the eyes. The support layer 4 also has through holes corresponding to the positions of the EEG grounding electrode 2211, EEG acquisition electrode 2212, EEG reference electrode 2213, skin electric field acquisition electrode 2221, and skin electric field reference electrode 2222, so that these electrodes can directly contact the human skin to achieve effective measurement of relevant signals.

[0033] Based on the aforementioned phototherapy eye mask, continue to refer to... Figure 1 The aforementioned lighting device 24 can preferably be two LED lights that can switch between orange light and full-spectrum white light, and are respectively set on the hardware layer 2 at positions corresponding to the eyes of the human body after wearing the phototherapy eye mask. More preferably, they are ring-shaped RGB LED lights, which can avoid direct exposure to the eyes and cause damage. The orange light has a sleep-inducing effect, while the full-spectrum white light can regulate emotions. By placing the two LED lights at positions corresponding to the eyes, the emitted light can quickly reach the eyes for corresponding light stimulation regulation.

[0034] refer to Figure 3 , Figure 3This is a schematic diagram of the control module of another embodiment of the phototherapy eye mask provided by this utility model. The phototherapy eye mask may also include a timing device 28 and a switch device 29 that are communicatively connected to the main control device 21. The timing device is used to start timing the illumination time after the switch device is turned on, and the main control device is used to turn off the lighting device after the time is reached. Specifically, in this case, after the switch device of the phototherapy eye mask is pressed and started, each hardware device is initialized, and the user can set the illumination time (e.g., 20 minutes to 60 minutes). The timing is started while the light is being emitted, and the light automatically stops once the set time is reached. This embodiment has two advantages: First, this personalized setting can meet the needs of different users, because each person's phototherapy needs may vary depending on their physical condition, lifestyle, or treatment purpose. Therefore, users can set their own usage time, making phototherapy more tailored to their individual circumstances and improving the phototherapy effect. Second, the timer function helps ensure safe use. By setting the light exposure time, users can avoid the potential risks of prolonged use of the eye mask, such as eye fatigue or discomfort. Once the set time is reached, the light exposure automatically stops, effectively protecting the user's eye health and improving user convenience. Users do not need to constantly monitor the light exposure time, allowing them to focus more on other tasks while enjoying the comfortable experience of phototherapy. After the light exposure time is set, the eye mask defaults to sleep aid mode, where the light source is orange-yellow. Then, various sensors start working: the heart rate and blood oxygen sensor monitors the body's heart rate and blood oxygen, the infrared temperature sensor monitors the body temperature, the EEG signal acquisition device monitors brain activity, and the skin conductance signal acquisition device monitors skin conductance. When these signals are analyzed and it is determined that the mood needs to be regulated, the main control device switches the light color to full-spectrum white light with mood-regulating function until the mood regulation is completed, and then switches back to orange-yellow light with sleep aid function. These switching processes are automatically completed without user intervention, thus improving the user experience.

[0035] In yet another embodiment of the aforementioned phototherapy eye mask, continuing to refer to... Figure 1 The eye mask body layer 1 may include a light-blocking plate 11 and eye mask straps 12 located on both sides of the light-blocking plate 11. The two eye mask straps 12 have detachable connecting parts, preferably Velcro or buckles. In this case, the two eye mask straps can be wrapped around the user's head to the back of the head and then fastened together with Velcro or buckles. This ensures that the phototherapy eye mask does not easily fall off when the user is lying down. Of course, other methods can also be used for fixation, such as setting two loops to be placed around the user's ears for fixation. The appropriate fixation method can be selected according to actual needs; there are no limitations here.

[0036] The types of devices specifically used in the aforementioned phototherapy eye mask can be as follows:

[0037] The aforementioned main control device can use the STM32F103C8T6 microcontroller as its core processor. This series of microcontrollers employs a high-performance ARM Cortex-M32 32-bit RISC core, operates at a frequency of 72MHz, has built-in high-speed memory, abundant enhanced I / O ports, and includes both standard and advanced communication interfaces. Its rich peripheral devices make it suitable for a variety of applications. The STM32F103C8T6's peripheral circuitry mainly includes a USB interface circuit, LED control circuit, boot mode selection circuit, reset control circuit, power control circuit, crystal oscillator circuit, and external battery power supply circuit, offering advantages such as high speed, strong expandability, comprehensive peripherals, and low power consumption.

[0038] The aforementioned lighting device can use an RGB LED light strip. This ring-shaped light strip avoids direct light shining into the eyes and can cause eye damage. It consists of red, green, and blue LEDs and uses the PWM (Pulse Width Modulation) function of the STM32 microcontroller to control the color and brightness of the red, green, and blue channels of the RGB lights. These PWM signals consist of high and low levels, and the duty cycle is the ratio of the high-level time to the entire time interval (i.e., duty cycle = PWM pulse width / timer period). In controlling the RGB lights, the output voltage or current can be adjusted by changing the duty cycle of the PWM signal, thereby controlling the brightness of the LED. When the duty cycle of the pulse signal increases, the voltage or current of the output signal also increases accordingly, thus increasing the brightness of the LED; conversely, when the duty cycle decreases, the brightness of the LED decreases. For example, when the duty cycle of the red channel is at its maximum, while the duty cycles of the green and blue channels are zero, the LED will display red. Similarly, by adjusting the duty cycle of each channel, various colors of light can be generated, thus achieving LED color control. The green and blue channels follow the same principle. In RGB color mode, each color is composed of red, green, and blue. Colors are defined by a hexadecimal symbol composed of the values ​​of red, green, and blue (RGB). The minimum value for each color is 0 (hexadecimal: #00), and the maximum value is 255 (hexadecimal: #FF). By calculating 256 * 256 * 256, the values ​​of red, green, and blue from 0 to 255 can combine to create 16 million different colors. Thus, by changing different RGB color values ​​and duty cycles, the color and brightness of RGB lights can be controlled, thereby obtaining the desired orange-yellow light and full-spectrum white light. RGB LED strip interfaces typically use a single-wire (DIN) communication method, requiring both VCC (positive) and GND (ground) power supplies. Specifically, the VCC pin of the RGB LED strip is connected to the 5V power supply pin of the STM32 development board, the GND pin is connected to the GND pin of the STM32 development board, and the data input (DIN) pin is connected to the selected GPIO pin of the STM32.

[0039] The heart rate and blood oxygenation acquisition component can use the MAX30102, which is a pulse oxygen saturation (SpO2) and heart rate (HR) sensor that integrates infrared (IR) and visible light (Red) LEDs. When infrared light passes through the skin, it is absorbed by hemoglobin (Hb), while when red light passes through the skin, it is absorbed by oxyhemoglobin (HbO2). Therefore, SpO2 and HR can be calculated by measuring the intensity of these absorbed light rays. The MAX30102 reads the absorption values ​​of the two light sources and stores them in a buffer that can be read via I2C. Specifically, the SDA and SCL pins of the MAX30102 are connected to the I2C data pin and I2C clock pin of the STM32, respectively; GND is connected to the ground pin of the STM32; and VCC is connected to the power supply pin of the STM32.

[0040] The Gestational Skin Signal Acquisition (GSR) component mainly consists of three parts: a sensor, a signal conversion and transmission circuit, and nerve cells with special proteins. These three components enable the reception, conversion, and transmission of tactile signals. After signal reception, a conversion and transmission circuit converts resistance changes into electrical pulse signals. As pressure increases, the frequency of the electrical pulses also increases accordingly. The amplitude of the stimulus is changed by controlling the sensation and size of the sensory area through the pulse magnitude. An amplifier amplifies the signal recorded by the sensor array. Finally, an LED array converts the electrical signal into a light signal, which is then transmitted to a special nerve cell. This nerve cell absorbs the light signal and converts it into a neural electrical signal, thus realizing the transmission of neural signals. Specific connection method: The GSR output pin (OUT) is connected to the STM32's ADC input pin, and the power supply (VCC) and ground (GND) are connected to the STM32's power supply and ground pins, respectively.

[0041] The EEG signal acquisition component can utilize the TGAM chip module, a highly integrated single-chip EEG sensor. It acquires raw EEG data through three dry electrodes, which are then processed to obtain raw EEG wave data. The electrodes serve as the contact points for EEG wave acquisition. After processing by the microcontroller, the EEG signals are transmitted to the app via Bluetooth to achieve the function of acquiring EEG wave data. Following the internationally accepted electrode placement method for the 10-20 EEG system, the ground electrode is placed in the center of the forehead, 10% backward from the root of the nose. The acquisition electrode is placed on the left side of the forehead, 10% to the left of the FPz (frontal midline), while the reference electrode is placed on the right side of the forehead. The specific connection method is as follows: communication is achieved using a serial interface. The TGAM TX (transmitter) is connected to the STM32's RX (receiver), the TGAM RX (receiver) is connected to the STM32's TX (transmitter), the ground GND is connected to the STM32's GND, and the power supply VCC is connected to the STM32's power pin.

[0042] The display device can use an OLED, with pins VCC, GND, SCL, and SDA. VCC is the power supply pin, used to provide power to the module, connected to the STM32's power supply pin. GND is the ground pin, connected to the STM32's GND. SCL is the clock pin, used for the clock signal during data transmission, connected to the STM32's clock pin supporting IIC communication. SDA is the data pin, used for data transmission, connected to the corresponding IIC data pin on the STM32.

[0043] The temperature sensing element used in the body temperature acquisition component can be the MLX90614 infrared thermopile temperature sensor. The MLX90614 has a small package structure and only 4 pins. When connecting the MLX90614 sensor to the STM32 microcontroller, first connect the GND pin to the STM32's ground, connect VCC to the STM32's power supply pin, and connect SDA and SCL to the STM32's I2C data pin and I2C clock pin, respectively. The STM32 microcontroller can control the timing of the infrared temperature sensor through the MLX_SCL serial clock signal line and read the temperature value measured by the MLX90614 sensor through the MLX_SDA serial data line.

[0044] The wireless communication device can use the HC-05 Bluetooth module, where TX and RX correspond to the TX and RX pins of USART2 on the STM32 board, respectively. On the STM32, the relevant parameters of USART2 need to be configured, including baud rate, data bits, and stop bits, to match the HC-05 settings. After the HC-05 Bluetooth module enters AT command mode, parameters such as master / slave mode, pairing password, and baud rate can be set via AT commands. The specific connection method is as follows: connect the HC-05's RX to the corresponding USART transmit pin on the STM32, connect the HC-05's TX to the STM32's USART receive pin, connect VCC to the STM32's power supply pin, and connect GND to the STM32's GND.

[0045] The following explains the process of using the aforementioned phototherapy eye mask:

[0046] 1. System startup and hardware initialization

[0047] When the user turns on the power switch to start the eye mask, the battery or external power supply powers all hardware modules, and the STM32 main control device starts and initializes all peripheral devices.

[0048] 2. User sets lighting time

[0049] Users input the illumination time (20-60 minutes) via buttons or a touch interface. The STM32 main control device reads the input and records the time using its internal timing device. The timing starts after the illumination is activated, ensuring that the light source is automatically turned off after the set time is reached.

[0050] 3. The eye mask begins to function normally.

[0051] (1) Default sleep aid mode activated

[0052] Orange-yellow sleep-aid light source activation: After initialization, the STM32 main controller can activate the orange-yellow sleep-aid light source via a PWM control output signal. The PWM control signal determines the brightness of the LED, ensuring a soft and moderate light output.

[0053] (2) Sensor module startup:

[0054] Heart rate and blood oxygen sensor (MAX30102): Communicates with STM32 via I2C interface to monitor the user's heart rate and blood oxygen level in real time. The sensor collects data and transmits the results to STM32.

[0055] Infrared temperature sensor (MLX90614): Also communicates with STM32 via I2C to measure the user's body surface temperature in real time, ensuring that the user's body temperature is within a safe range.

[0056] TGAM EEG module: Transmits the user's brainwave data to the STM32 via the UART interface. The EEG data includes alpha waves, beta waves, etc. The system judges the user's emotional state based on different EEG wave types.

[0057] Skin conductance (GSR) module: It collects changes in skin conductivity through the ADC pin. Skin conductance reflects the user's emotional fluctuations, and the signal is transmitted to the STM32 at any time.

[0058] 4. Data processing and sentiment state assessment

[0059] (1) Physiological data collection:

[0060] The STM32 main control chip periodically reads data from sensors such as heart rate, blood oxygen, electroencephalogram (EEG), and electrodermal conductivity (EDS), and processes this data through built-in algorithms.

[0061] (2) Logic of emotion judgment:

[0062] EEG data processing: The STM32 analyzes the EEG data transmitted from the TGAM module. For example, increased beta waves indicate anxiety or emotional fluctuations, while increased alpha waves indicate a relaxed state.

[0063] Electrodermal data processing: Skin conductivity is closely related to emotional state. When a user is nervous, skin conductivity will increase. STM32 judges emotional fluctuations by reading voltage changes through ADC.

[0064] (3) Emotional judgment results:

[0065] If the brainwave and skin conductivity exceed the set threshold, it indicates that the user's emotions are fluctuating greatly (such as anxiety or stress), and the system will trigger a light source switch.

[0066] If the emotional state is normal, the system will maintain the sleep aid mode.

[0067] 5. Automatic light source switching

[0068] (1) Light source switching logic:

[0069] When the STM32 detects fluctuations in the user's emotions, it gradually reduces the brightness of the orange LED light source through PWM output, while increasing the brightness of the full-spectrum white light to ensure a smooth and natural switching process.

[0070] When the mood stabilizes, the STM32 gradually reduces the brightness of the white light using the same PWM adjustment method, restoring the orange light source to continue aiding sleep.

[0071] (2) PWM signal control:

[0072] The brightness of two LED light sources is controlled by the PWM module of STM32, gradually adjusting the brightness of the light sources to avoid discomfort caused by sudden switching.

[0073] Orange-yellow sleep aid light (low-frequency PWM): The light source brightness is suitable for sleep, with a low PWM duty cycle.

[0074] Full-spectrum white light (high-frequency PWM): When emotions fluctuate, the PWM duty cycle increases, providing brighter white light to regulate emotions.

[0075] 6. Timer control and automatic light stop

[0076] (1) Timer function:

[0077] The STM32's timer starts counting down based on the user-defined illumination time. During this time, the system continuously monitors the user's physiological data and adjusts the light source accordingly. When the timer reaches the user-defined time (e.g., 30 minutes or 60 minutes), the STM32 automatically turns off all light sources, and the eye mask stops working.

[0078] (2) Light source shutdown logic:

[0079] When the timer ends, the STM32 uses a PWM signal to gradually reduce the brightness of the LED until it is completely off, so as to avoid disturbing the user by suddenly turning off the light source.
