[0002] In daily life, when engaging in close-range work or study, the required lighting area changes with the user's position and the direction of their gaze. Therefore, effective adjustment of ambient lighting has become a focus of attention. Existing methods for adjusting ambient lighting involve using lighting equipment to capture user images, observing the user's eye movements, analyzing these movements to determine the user's real-time gaze direction, and then adjusting the lighting area accordingly.

[0003] However, existing methods, on the one hand, limit the location of lighting equipment and require it to be user-facing; on the other hand, they determine the lighting area by analyzing data from a single user image, which is not only less accurate but also has the potential to infringe on user privacy.

Therefore, the first communication module and the second communication module should adopt the same communication method. For example, if the first communication module is a Bluetooth communication module, the second communication module is a Bluetooth communication module that matches the first communication module.

[0053] In one specific embodiment, the first communication module may include a signal transmitting antenna, and the second communication module may include a received signal strength indicator (RSSI) and a signal receiving antenna.

[0060] In one specific embodiment, a light sensor can be used to collect light data of the environment in which the target object is located.

[0061] As can be seen from the above embodiments, by collecting the brainwave signal data of the target object through the forehead EEG sensor, the target blink data of the target object can be obtained, and the lighting can be adjusted according to the eye fatigue information corresponding to the target blink data, which can further improve the accuracy of environmental lighting adjustment.

[0062] In an optional embodiment, the lighting device may further include a third communication module, which is electrically connected to the second controller.

[0067] The following describes an ambient lighting adjustment method provided by an embodiment of this application. This method is implemented based on the aforementioned head-mounted wearable device. Figure 3 This is a flowchart illustrating an ambient lighting adjustment method provided in an embodiment of this application. It should be noted that this specification provides the operational steps of the method as described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only execution order. In actual system or product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 3 As shown, the above method may include:

[0068] S301, the head-worn device acquires first position parameters of the target object relative to the head-worn device based on an angle sensor, a range sensor, and a first magnetometer sensor.

[0069] In the embodiments described in this specification, the target object can be the object that is closest to the head-wearing device in the direction of the eye gaze of the target object wearing the head-wearing device.

[0070] In one specific embodiment, the first position parameter may include: viewing angle data of the target object wearing the head-wearing device, first orientation angle data of the head-wearing device, and first distance data between the head-wearing device and the target object;

[0071] Correspondingly, such as Figure 4 As shown, the head-wearing device described above, based on an angle sensor, a range sensor, and a first magnetometer sensor, can acquire first position parameters of the target object relative to the head-wearing device, which may include:

[0072] S401, the head-worn device collects the viewing angle data of the target object through an angle sensor.

[0073] Specifically, the viewing angle data can be the angle between the head position of the target object and the upright position of the head. When the target object is in a level view, the viewing angle data is 0°; when the target object is in a downward view, the viewing angle data is greater than 0°; and when the target object is in a downward view, the viewing angle data is less than 0°.

[0074] S402, the head-worn device collects the first distance data through a ranging sensor.

[0075] Specifically, the first distance data is the distance from the target object's eye gaze direction to the target object's viewing direction.

[0076] S403, the head-worn device collects first orientation angle data through the first magnetometer sensor.

[0077] Specifically, the first orientation angle data can be the angle between the head-wearing device and due north. In an optional embodiment, the first orientation angle data can be a clockwise angle.

[0078] As can be seen from the above embodiments, by collecting the position parameters of the target object through the angle sensor, distance sensor and first magnetometer sensor of the head-worn device, the accuracy of the first position information positioning can be improved, so as to accurately locate the target position information of the target object relative to the lighting device, thereby improving the accuracy of the ambient lighting adjustment.

[0079] S302, the head-worn device sends a target signal to the lighting device, the target signal carrying a first position parameter.

[0080] In the embodiments described in this specification, the head-wearing device sends a target signal to the lighting device through a first communication module, and the lighting device receives the target signal sent by the head-wearing device through a second communication module.

[0081] S303, the lighting device acquires a second position parameter relative to the head-worn device based on the received target signal and the second magnetometer sensor.

[0082] In one specific embodiment, the second position parameter may include: second orientation angle data of the lighting device, downward angle data of the lighting device relative to the head-wearing device, and second distance data between the head-wearing device and the lighting device;

[0083] Correspondingly, such as Figure 5 As shown, the lighting device, based on the received target signal and the second magnetometer sensor, can obtain a second position parameter of the lighting device relative to the head-worn device, which may include:

[0084] S501, the lighting equipment performs signal analysis on the received target signal to obtain the signal strength and signal reception angle.

[0085] In one specific embodiment, the received signal power can be obtained through the Received Signal Strength Indicator (RSSI) in the second communication module, and the signal strength can be measured using the signal power; and the signal receiving angle can be determined through the signal receiving antenna in the second communication module. Specifically, the signal receiving angle can be the angle between the signal receiving direction of the lighting device and the horizontal plane in space.

[0086] S502, the lighting equipment determines the second distance data based on the signal strength.

[0087] In practical applications, a relationship model between signal strength and second distance data can be pre-built based on a large amount of experimental data. Based on the received signal strength and the relationship model, the second distance data corresponding to the received signal strength can be determined.

[0088] S503, the lighting equipment uses the signal reception angle as the depression angle data.

[0089] In practical applications, the signal reception angle is usually equal to the angle of depression of the lighting device relative to the head-mounted device.

[0090] S504, the lighting equipment collects second orientation angle data through the second magnetometer sensor.

[0091] Specifically, the second direction angle data can be the angle between the lighting device and the due north direction. In an optional embodiment, the second direction angle data can be a clockwise angle.

[0092] As can be seen from the above embodiments, the second distance data, depression angle data, and second orientation angle data obtained by the second magnetometer sensor after the lighting device analyzes the received target signal can improve the accuracy of the second position information positioning, so as to accurately locate the target position information of the target object relative to the lighting device, thereby improving the accuracy of the ambient lighting adjustment.

[0093] S304, the lighting device determines the target position information of the target object relative to the lighting device based on the first position parameter and the second position parameter.

[0094] In a specific embodiment, such as Figure 6 As shown, the lighting device, based on the first position parameter and the second position parameter, determines the target position information of the target object relative to the lighting device, which may include:

[0095] S601, the lighting device performs positioning analysis based on the viewing angle data and the first distance data to determine the first position information of the target object relative to the head-worn device.

[0096] In the embodiments of this specification, it is assumed that the head of the target object is facing the target object. Therefore, the orientation angle of the head-wearing device is the same as the orientation angle of the target object. When the orientation angles of the two are the same, the head-wearing device can be used as a reference object to determine the first position information based on the viewing angle data and the first distance data.

[0097] S602, the lighting device performs positioning analysis based on the target direction angle, depression angle data and second distance data to determine the second position information of the lighting device relative to the head-worn device, where the target direction angle is the difference between the first direction angle data and the second direction angle data.

[0098] Specifically, the target orientation angle can be used to determine the orientation between the target object corresponding to the head-mounted device and the lighting device, thereby determining whether the target object is facing the light source or facing away from the light source, and further determining the above-mentioned second position information based on the depression angle data and the second distance data.

[0099] S603, the lighting equipment performs positioning analysis based on the first position information and the second position information to determine the target position information.

[0100] As can be seen from the above embodiments, on the one hand, the lighting device first determines the first position information of the target object relative to the head-mounted device based on the viewing angle data and the first distance data. Then, it determines the second position information of the lighting device relative to the head-mounted device based on the target orientation angle, depression angle data, and the second distance data. Finally, based on the first and second position information, it determines the target position information of the target object relative to the lighting device. This can effectively locate the spatial position relationship between the target object and the lighting device, thereby accurately locating the target lighting area and improving the accuracy of ambient lighting adjustment. On the other hand, there is no need to limit the position of the lighting device. Through data linkage between the head-mounted device and the lighting device, the lighting device performs positioning analysis. While avoiding the power consumption of the head-mounted device, the lighting of the curved light-emitting module can be directly adjusted based on the positioning results, improving the efficiency and flexibility of ambient lighting adjustment.

[0101] S305, the lighting equipment controls the light-emitting unit in the curved light-emitting module that corresponds to the target position information to provide illumination based on the target position information.

[0102] Specifically, different positional information with the lighting device as a reference can be pre-defined to correspond to the orientation of the light-emitting units in the curved surface light-emitting module. Based on the target positional information, the light-emitting units in the curved surface light-emitting module that are in the orientation corresponding to the target positional information can be controlled to illuminate, so that the illumination range can cover the area corresponding to the target positional information.

[0103] As can be seen from the above embodiments, lighting adjustment through curved light-emitting modules can effectively cover all areas of the room, meet the lighting needs of all directions, and improve the universality of environmental lighting adjustment.

[0104] In the embodiments described in this specification, such as Figure 7 As shown, the above method may further include:

[0105] S701, a head-worn device, uses a forehead EEG sensor to acquire target blink data of the target object.

[0106] In the embodiments of this specification, the target blink data can be statistical data associated with the blinking action of the target object. Specifically, the target blink data can include: blinking frequency and the duration of each blink intensity under multiple blink intensities.

[0107] In one specific embodiment, the head-wearing device described above, based on a forehead EEG sensor, can acquire target blink data of the target object, which may include:

[0108] 1) The head-worn device collects the target's brainwave signal data within a preset time period using a frontal EEG sensor.

[0109] Specifically, the EEG signal data can be amplitude statistics of the frontal EEG signal, which may include the amplitude standard deviation. In practical applications, the sampling frequency of the frontal EEG signal can be set according to the sampling precision; in an optional embodiment, the sampling frequency can be 1 kHz.

[0110] 2) The head-worn device traverses the EEG signal data at multiple times within a preset time period.

[0111] Specifically, multiple time points can be set based on the accuracy of eye fatigue monitoring. In an optional embodiment, the multiple time points may include every second within a 60-second period.

[0112] 3) If the current EEG signal data is greater than the blink signal threshold, the head-worn device will add the current EEG signal data to the blink state data group.

[0113] Specifically, at preset judgment frequencies, it is determined whether the current EEG signal data is greater than the blink signal threshold. If the current EEG signal data is greater than the blink signal threshold, the state corresponding to the current EEG signal data is determined to be the blinking state.

[0114] In one specific embodiment, the method for determining the blink signal threshold may include:

[0115] (1) The head-worn device acquires the first EEG signal data during the target object's eye-closing process and the second EEG signal data during the blinking process;

[0116] Specifically, the first EEG signal data can be the amplitude standard deviation of the frontal EEG signal during the target subject's eye-closing process, and the second EEG signal data can be the amplitude standard deviation of the frontal EEG signal during the target subject's blinking process. In an optional embodiment, the first EEG signal data is acquired during the 10-second period when the target subject's eyes are closed, and the second EEG signal data is acquired during the 10-second period when the target subject blinks.

[0117] (2) The head-worn device determines the blink signal threshold based on the first EEG signal data and the second EEG signal data.

[0118] Specifically, the average of the first and second EEG signal data can be calculated and used as the blink signal threshold.

[0119] 4) After traversing the EEG signal data at multiple moments within the preset time period, the head-worn device performs statistical analysis on the EEG signal data in the blink state data group to obtain the blink frequency and the duration corresponding to various blink intensities.

[0120] Specifically, the number of EEG signal data in the corresponding blink state data group within a preset time period is counted to obtain the blink frequency.

[0121] Specifically, multiple intensity thresholds can be set between the blink signal threshold and the aforementioned second EEG signal data. In practical applications, the values ​​of the multiple intensity thresholds can be set in conjunction with the discrimination accuracy of blink intensity. In an optional embodiment, the multiple intensity thresholds may include a first intensity threshold and a second intensity threshold, wherein the first intensity threshold is less than the second intensity threshold. When the EEG signal data is greater than the blink signal threshold but less than or equal to the first intensity threshold, the target blink state corresponding to the EEG signal data is considered to be a low-intensity blink. When the EEG signal data is greater than the first intensity threshold but less than or equal to the second intensity threshold, the target blink state corresponding to the EEG signal data is considered to be a medium-intensity blink. When the EEG signal data is greater than the second intensity threshold but less than or equal to the second EEG signal data, the target blink state corresponding to the EEG signal data is considered to be a high-intensity blink.

[0122] Accordingly, the duration of blinking states corresponding to the EEG signal data within a preset time period is statistically analyzed, thereby determining the duration of low-intensity blinking, medium-intensity blinking, and high-intensity blinking within that time period.

[0123] As can be seen from the above embodiments, by collecting the EEG signal data of the target object, the target blink data of the target object can be obtained, so as to facilitate subsequent eye fatigue detection.

[0124] S702, the head-worn device collects lighting data of the environment in which the target object is located through a light sensor.

[0125] Specifically, illumination data may include, but is not limited to: illuminance, flicker, color rendering index, and color temperature.

[0126] S703, the head-worn device detects eye fatigue based on the target's blink data and viewing angle data, and obtains the target's eye fatigue information.

[0127] In the embodiments of this specification, eye fatigue information can be the degree of eye fatigue, which characterizes the state of eye fatigue.

[0128] In one specific embodiment, eye fatigue information may include eye fatigue values ​​that quantify the degree of eye fatigue according to certain rules.

[0129] In one specific embodiment, the fatigue level corresponding to the eye fatigue value can be determined based on a comparison between the eye fatigue value and the eye fatigue threshold. Optionally, the eye fatigue threshold may include a first fatigue threshold and a second fatigue threshold, wherein the first fatigue threshold is less than the second fatigue threshold. Specifically, when the eye fatigue value is less than the first fatigue threshold, the fatigue level corresponding to the eye fatigue value is mild eye fatigue; when the eye fatigue value is greater than or equal to the first fatigue threshold and less than the second fatigue threshold, the fatigue level corresponding to the eye fatigue value is moderate eye fatigue; and when the eye fatigue value is greater than or equal to the second fatigue threshold, the fatigue level corresponding to the eye fatigue value is severe eye fatigue.

[0130] In practical applications, the first fatigue threshold and the second fatigue threshold can be preset by combining the precision of ambient lighting adjustment and the range of eye fatigue values.

[0131] In one specific embodiment, the aforementioned head-worn device detects eye fatigue based on target blink data and viewing angle data, and the resulting eye fatigue information for the target object may include:

[0132] The head-mounted device inputs the target's blink data and viewing angle data into the eye fatigue detection network to detect eye fatigue and obtain eye fatigue information.

[0133] In practical applications, the aforementioned eye fatigue detection network can be obtained by training a pre-defined eye fatigue detection network using blink data of sample objects that includes labels indicating eye fatigue. Specifically, the aforementioned eye fatigue detection network may include, but is not limited to, GRU (Gated Recurrent Unit Network), RNN (Recurrent Neural Network), or LSTM (Long Short-Term Memory Network).

[0134] As can be seen from the above embodiments, by training a preset eye fatigue detection network based on sample data, an eye fatigue monitoring network with high generalization ability is obtained, thereby improving the accuracy of eye fatigue detection.

[0135] S704, the head-worn device sends eye fatigue information and light data to the lighting equipment.

[0136] S705, when eye fatigue information meets preset conditions, the lighting equipment adjusts the lighting of the curved light-emitting module based on the illumination data.

[0137] In the embodiments of this specification, the preset conditions can be set in combination with the needs of eye health and ambient light adjustment in actual applications. In an optional embodiment, the preset condition can be that the fatigue level corresponding to the eye fatigue information is high eye fatigue.

[0138] In an optional embodiment, the lighting device adjusting the illumination of the curved surface light-emitting module based on illumination data may include:

[0139] When the ambient light intensity indicated by the illumination data is less than the first brightness threshold, the lighting device increases the illuminance of the currently working light-emitting unit in the curved light-emitting module;

[0140] Alternatively, when the ambient light intensity indicated by the illumination data exceeds a second brightness threshold, the lighting device reduces the illuminance of the currently operating light-emitting unit.

[0141] In the embodiments described in this specification, the first brightness threshold may be less than the second brightness threshold. In practical applications, the first brightness threshold and the second brightness threshold can be preset based on the current ambient light intensity requirements, and the variation range of the illuminance of the currently operating light-emitting unit can also be preset based on the eye health requirements of the target object and the current ambient light intensity requirements.

[0142] In another optional embodiment, the lighting device's adjustment of the curved surface light-emitting module's illumination based on illumination data may further include:

[0143] When the ambient light intensity indicated by the illumination data is less than the first brightness threshold, the lighting device increases the number of working light-emitting units in the curved light-emitting module;

[0144] Alternatively, when the lighting data indicates that the ambient light intensity is greater than a second brightness threshold, the lighting device reduces the number of working light-emitting units.

[0145] In practical applications, the variation range of the number of light-emitting units described above can be preset based on the target user's eye health needs and the current ambient light intensity requirements. For example, if 50% of the light-emitting units in the curved surface light-emitting module are currently emitting light, and the current illumination data indicates that the ambient light intensity is less than a first brightness threshold, then 70% of the light-emitting units in the curved surface light-emitting module will be emitting light; if the current illumination data indicates that the ambient light intensity is greater than a second brightness threshold, then 30% of the light-emitting units in the curved surface light-emitting module will be emitting light.

[0146] As can be seen from the above embodiments, when the eye fatigue information meets the preset conditions, adjusting the lighting of the curved light-emitting module based on the illumination data can further improve the accuracy of the ambient lighting adjustment, meet the user's lighting needs, and enhance the user experience.

[0147] As can be seen from the above embodiments of this application, the technical solution provided by this application, on the one hand, firstly, the lighting device determines the first position information of the target object relative to the head-mounted device based on the viewing angle data and the first distance data, then determines the second position information of the lighting device relative to the head-mounted device based on the target orientation angle, depression angle data, and the second distance data, and finally determines the target position information of the target object relative to the lighting device based on the first and second position information. This can effectively locate the spatial position relationship between the target object and the lighting device, thereby accurately locating the target lighting area and improving the accuracy of ambient lighting adjustment. On the other hand, it does not require limiting the position of the lighting device; through data linkage between the head-mounted device and the lighting device, the lighting device can achieve the desired position. The device performs location analysis, avoiding the power consumption of wearable headgear while directly adjusting the lighting of the curved light-emitting module based on the location results, improving the efficiency and flexibility of ambient lighting adjustment. Furthermore, adjusting the lighting through the curved light-emitting module effectively covers various areas of the room, meeting lighting needs from all directions and enhancing the universality of ambient lighting adjustment. Additionally, by collecting EEG signal data from the target object, target blink data is obtained. When the eye fatigue information corresponding to the target blink data meets preset conditions, adjusting the lighting of the curved light-emitting module based on the illumination data further improves the accuracy of ambient lighting adjustment, meeting user lighting needs and enhancing the user experience.
