[0039] Figure 1 This is a schematic diagram of the structural composition of the electronic device in this application. Figure 1This electronic device can be applied to virtual environments, including but not limited to Virtual Reality (VR) devices, Augmented Reality (AR) devices, Mixed Reality (MR) devices, Cognitive Reality (CR) devices, and Extended Reality (XR) devices, such as... Figure 1 As shown, the electronic device includes: a device body 10, a physiological sensor 20, a processor 30, and a controller 40. The device body 10 has a display component 101 and a covering component 102. The display component 101 is used to present a target recommended scene from a virtual environment to the target user. The covering component 102 is used to fit against the target part of the target user to fix the device body 10. The covering component 102 also has multiple mounting slots 1021. Each mounting slot 1021 has a snap-fit ​​structure (not shown) on its inner wall. The physiological sensor 20 is disposed within the mounting slot 1021 and can be fixed to the mounting slot 1021 by snap-fit ​​structure. The physiological sensor 20 is used to collect the target user's biometric data, which is generated based on simulated traffic safety education content in the target recommended scene. The processor 30 is located inside the main body 10 of the device and is connected to the physiological sensor 20. It is used to process and analyze the biometric data of the target user to obtain the emotional state of the target user in relation to the target recommended scene. The controller 40 is located inside the main body of the device and is connected to the processor. It is used to control the display component 101 to update the target recommended scene when the emotional state meets the scene update conditions.

[0040] Here, the display component 101 may include a display screen 1011 and a lens assembly 1012. The display screen 1011 typically includes two screens, corresponding to the left and right eyes respectively, for displaying different images so that the human eye can obtain image information with differences and generate a stereoscopic effect in the mind. The lens assembly 1012 refracts light to bring the image on the display screen 1011 closer to a position that the human eye's retina can clearly see.

[0041] Here, when the covering component 102 is a mask structure, the covering component 102 can fit against the face of the target user; when the covering component 102 is an eyeglass structure or an eye mask structure, the covering component 102 can fit against the eyes and / or forehead of the target user.

[0042] In this application, the covering component 102 can cover the outer surface of the physiological sensor 20, the processor 30 and the controller 40, and the contact surface of the covering component 102 can fit against the face of the target user to limit the target user's vision to the display area corresponding to the target recommended scene; the mounting groove 1021 is disposed at a first position of the covering component 102 facing the contact surface, and the first position can correspond to the forehead area of ​​the target user.

[0043] like Figure 2 As shown, the covering component 102 can be made of a soft-pack material, which may include a medical-grade silicone layer A1, a memory foam layer A2, and a thermally conductive silicone layer A3. The memory foam layer A2 is located between the medical-grade silicone layer A1 and the thermally conductive silicone layer A3, with the thermally conductive silicone layer A3 located on the side facing the user's skin. The medical-grade silicone layer A1 has good biocompatibility, a hardness of 35±5, breathability ≥3000g / m² / 24h, and a thickness of 0.8±0.1mm. The memory foam layer A2 is a high-density polyurethane memory foam with a density of 45±5kg / m³ and a thickness of 4±0.5mm. The thermally conductive silicone layer A3 has electromagnetic compatibility (EMI) shielding capabilities, a thermal conductivity ≥1.5W / m·K, and a thickness of 0.5±0.1mm.

[0044] like Figure 1 As shown, the main body 10 of the device also includes a fixing component 103; the first end and the second end of the fixing component 103 are respectively connected to the two sides of the main body 10 of the device, and are used to fix the main body 10 of the device at the head position of the target user; the fixing component 103 is also provided with an adjustment device 1031, which is used to adjust the length of the fixing component 103 according to the head size of the target user.

[0045] Here, the specific structure of the adjustment device 1031 is not limited, as long as it can achieve the effect of adjusting the length of the fixing component according to the head size of the target user.

[0046] In this application, the physiological sensor 20 may include a heart rate sensor 201, a skin conductance sensor 202, and a temperature sensor 203. The heart rate sensor 201 is located between the skin conductance sensor 202 and the temperature sensor 203, and is situated in the central region of the first position, in contact with the center of the target user's forehead. The skin conductance sensor 202 and the temperature sensor 203 are located on either side of the first position, in contact with the sides of the target user's forehead. The temperature sensor 203 has a measurement range of 32℃-42℃ and an accuracy of ±0.1℃. The skin conductance sensor 202 adopts a dual-electrode design with a response time of less than 100ms; the heart rate sensor 201 uses photoplethysmograph (PPG) technology to shine light into the skin and detect heart rate by collecting the different amounts of light refracted by changes in blood flow and measuring the blood perfusion of the dermis and subcutaneous tissue. Its size can be 4mm × 2mm × 1mm, and its response time is ≤1s.

[0047] Figure 3 This is a schematic diagram of the structural composition of the covering component in this application. Figure 2 ,like Figure 3 As shown, the covering assembly 102 further includes a protective layer A4 formed by a transparent protective layer and an anti-reflective coating, for covering the heart rate sensor 201. The heart rate sensor 201 may include a first sensor body 2011, a photodiode 2012, and a photodetector 2013. The photodiode 2012 and the photodetector 2013 are disposed on the side of the first sensor body 2011 near the skin contact surface of the target user. The photodiode 2012 is used as a light source to emit a first light signal to the skin contact surface. The photodetector 2013 is used to detect a second light signal remaining after the first light signal is transmitted and / or reflected by the skin, and converts the second light signal into an electrical signal and sends it to the first sensor body 2011. The first sensor body 2011 is used to obtain the heart rate data of the target user based on the electrical signal. The protective layer A4 covers the side of the photodiode 2012 and the photodetector 2013 near the skin contact surface, and the total thickness of the protective layer A4 can range from 0.2 mm to 0.5 mm.

[0048] Here, the protective layer A4 not only has high transparency, allowing good transmittance for both visible and near-infrared light, protecting sensitive optical components from dust, moisture, and physical damage, but it can also completely encapsulate the optical component area, allowing light signals to pass through and improving signal quality.

[0049] Figure 4 This is a schematic diagram of the structural composition of the covering component in this application. Figure 3 ,like Figure 4As shown, the covering component 102 further includes a conductive gel layer A5 for covering the surface of the skin conductance sensor 202. Here, the skin conductance sensor 202 may include a second sensor body 2021 and an electrode assembly 2022. The electrode assembly 2022 is disposed on the side of the second sensor body 2021 near the target user's skin contact surface, for transmitting a first electrical signal to the skin contact surface. This first electrical signal can generate a second electrical signal under the action of the skin. The second sensor body 2021 can obtain the target user's skin conductance data based on the second electrical signal. The conductive gel layer A5 covers the electrode surface of the electrode assembly 2022 on the side near the skin contact surface, and can directly contact the user's skin. Its thickness ranges from 0.5 mm to 1 mm.

[0050] In this application, the conductive gel layer A5 can improve the conductivity between the electrode and the skin, reduce the impedance between the skin and the electrode, keep the skin moist, and ensure stable signal quality.

[0051] Here, the conductive gel layer A5 is replaceable; for example, it can be a gel patch, such as Ag / AgCl hydrogel, which has good adhesion and conductivity. The conductive gel layer ensures optimal conductivity for each use of the electronic device, avoiding hygiene risks associated with bacterial growth.

[0052] Figure 5 This is a schematic diagram of the structural composition of the covering component in this application. Figure 4 ,like Figure 5 As shown, a portion of the thermally conductive silicone layer A3 of the covering component 102, specifically a thermally conductive silicone region A6, covers the temperature sensor 203. The temperature sensor 203 may include a third sensor body 2031 and a detection component 2032. The detection component 2032 is disposed on the side of the third sensor body 2031 near the target user's skin contact surface, and is used to detect the skin temperature from that skin contact surface. The third sensor body 2031 can obtain the target user's skin temperature data based on this skin temperature. The portion of the thermally conductive silicone region A6 is disposed on the side of the detection component 2032 near the skin contact surface. Because the thermally conductive silicone layer A6 has soft and deformable properties, it can directly contact the user's skin, adapting to the slight undulations of the skin surface. The portion of the thermally conductive silicone region A6 is circular or square, its size is slightly larger than the size of the temperature sensor 203, and its thickness ranges from 0.3 mm to 0.5 mm. The thermally conductive silicone area A6 not only fills the tiny gap between the temperature sensor 203 and the user's skin, reducing air isolation, but also improves heat conduction efficiency, ensuring accurate temperature measurement.

[0053] Figure 6This is a schematic diagram of the structural composition of the mounting slot in this application, as shown below. Figure 6 As shown, the inner wall of the mounting groove 1021 is also provided with a wiring hole 10211, and the inner wall of the wiring hole 10211 is provided with a ball bearing structure 10212. The signal line of the physiological sensor 20 is connected to the processor 30 through the wiring hole 10211, and the length and angle of the signal line can be adjusted by the action of the ball bearing structure 10212. Through the rolling characteristics of the ball bearing structure 10212, the breakage of the signal line can be avoided, and the wiring sensitivity of the signal line can be improved. The signal line can be composed of a silver-plated conductor layer, an insulation layer, a shielding layer, and a protective layer from the inside out, which has anti-interference capability.

[0054] In this application, the electronic device can store multiple scenarios to be recommended, each scenario having its own scenario attribute features. When a target user wears the electronic device, the electronic device can obtain the target user's user attribute features and match these user attribute features with the scenario attribute features of each scenario to be recommended to obtain the feature similarity between the target user's user attribute features and the scenario attribute features of each scenario to be recommended. The target recommended scenario can be determined through this feature similarity. In this way, it can not only reflect which scenario is more in line with the target user's actual needs, but also improve the accuracy of scenario recommendation.

[0055] Here, the scene attribute characteristics of the scene to be recommended can be set according to the actual purpose of the scene to be recommended.

[0056] For example, for traffic safety education recommendation scenarios, the scenario attribute characteristics may include, but are not limited to, user type and scenario type. The scenario type includes, but is not limited to, urban roads, national and provincial roads, county and township roads, and expressways. Furthermore, under each scenario type, there may be, but are not limited to, detailed scenario attribute characteristics such as inner wheel difference, ghost peek, drunk driving, driving without a driver's license, overloaded driving, U-turn on expressway, crossing the street in a turnaround, getting out of the car and running, and A-pillar blind spot.

[0057] This electronic device can use cosine similarity to calculate the similarity between user A and scene a, and between user B and scene b, using the following formula:

[0058] ;

[0059] ;

[0060] in:

[0061] User A's attribute characteristics are: [1,0,0,0,0, 1,0,0,0], representing a primary or secondary school student driving on urban roads;

[0062] User B's attribute characteristics are: [0,0,1,0,0, 0,0,1,0], representing a courier who drives on county and township roads;

[0063] The attribute characteristics of scenario a are: [0,1,0,0,0, 1,0,0,0], indicating that it is applicable to passenger and freight drivers and urban road scenarios;

[0064] The attribute characteristics of scenario b are: [0,0,1,0,0, 0,0,1,0], indicating that it is applicable to the scenario of deliverymen and county and township roads;

[0065] Based on the above calculation formula, the feature similarity values ​​of user A and user B in scene a and scene b are determined as follows:

[0066] User A:

[0067] Similarity to scene a: 0.5;

[0068] Similarity to scene b: 0;

[0069] User B:

[0070] Similarity to Scene 1: 0;

[0071] Similarity to scene b: 1;

[0072] Based on this feature similarity, the electronic device can sort the feature similarity of each scene to be recommended in descending order and select the scene with the highest feature similarity as the target recommended scene.

[0073] For example, following the example above, we can sort the similarity scores in descending order to generate an initial list of recommended scenarios for the user:

[0074] For user A: Scenario a has a high degree of similarity, so this scenario is recommended.

[0075] For user B: The similarity to scenario b is high, so this scenario is recommended.

[0076] Here, if the electronic device recommends only one target recommended scenario, the target recommended scenario can be presented directly to the target user in the virtual environment; if the scene recommending device recommends multiple target recommended scenarios, a list of recommended scenarios can be displayed to the target user in the virtual environment; then, the specific target recommended scenario determined by the target user for the recommended scenario list is monitored; finally, the specific target recommended scenario is displayed to the target user in the virtual environment.

[0077] In this application, biometric data of the target user is collected by physiological sensor 20. Based on this biometric data, the emotional state of the target user in relation to the target recommended scenario corresponds to a state attribute value. The processor 30 determines the state attribute corresponding to the experience state by comparing this state attribute value with a state threshold. If the state attribute indicates ease, the experience state meets the scenario update condition, thereby triggering the controller 40 to control the display component 101 to update the current target recommended scenario to a first recommended scenario, wherein the difficulty attribute value of the first recommended scenario is higher than the current difficulty attribute value of the target recommended scenario. If the state attribute indicates tension, the experience state meets the scenario update condition, thereby triggering the controller 40 to control the display component 101 to update the current target recommended scenario to a second recommended scenario, wherein the difficulty attribute value of the second recommended scenario is lower than the current difficulty attribute value of the target recommended scenario. If the state attribute indicates moderate tension, the experience state does not meet the scenario update condition, thus maintaining the current target recommended scenario for the target user.

[0078] Here, tension corresponds to a first state threshold range, moderate corresponds to a second state threshold range, and relaxed corresponds to a third state threshold range. The first state threshold range is greater than both the second and third state threshold ranges, and the second state threshold range is greater than the third state threshold range. When the state attribute value falls within the first state threshold range, the state attribute is determined to represent tension; when the state attribute value falls within the second state threshold range, the state attribute is determined to represent moderate; and when the state attribute value falls within the third state threshold range, the state attribute is determined to represent relaxed.

[0079] The electronic device provided in this application, through the combination of virtual technology and physiological sensors, can not only realize personalized traffic safety education for different key groups, but also accurately judge the sensitivity and cognitive level of the user to different dangerous scenarios based on the user's emotional state, realize dynamic adjustment of scenarios for different users, and improve the teaching quality of traffic safety education.

[0080] Figure 7 This is a schematic diagram of the structural composition of the electronic device in this application. Figure 2 ,like Figure 7As shown, the electronic device also includes a video decoder 50, a timer 60, and a time compensator 70. The video decoder 50 is connected to the display component 101 and records the time encoding of the image signal when the display component 101 displays the image signal of the target recommended scene. One end of the timer 60 is connected to the video decoder 50, and the other end is connected to the physiological sensor 20. It triggers the physiological sensor 20 to collect biometric data of the target user within a preset sampling period based on the time encoding recorded by the video decoder 50, thereby achieving synchronization between data collection and scene playback. The time compensator 70 is connected to the physiological sensor 20 and compensates for any response delay in the physiological sensor 20, ensuring synchronization between data collection and scene playback.

[0081] Here, during system initialization, the sampling parameters of temperature sensor 203, skin conductance sensor 202, and heart rate sensor 201 can be configured: temperature sensor 203: sampling rate 100Hz, ADC channel 1; heart rate sensor 201: sampling rate 200Hz, ADC channel 2; skin conductance sensor 202: sampling rate 500Hz, ADC channel 3. Timer 60 can generate a 10ms reference sampling clock based on a preset time interval (e.g., 10ms); the DMA channel is used to implement polling sampling of temperature sensor 203, skin conductance sensor 202, and heart rate sensor 201. Video decoder 50 can output an SMPTE timecode signal by parsing the image signal of the currently output target recommended scene; using the timecode of video decoder 50 as the master clock source, it is synchronized with the master clock through a PLL phase-locked loop. The timecode signal can trigger temperature sensor 203, skin conductance sensor 202, and heart rate sensor 201 to collect data according to the sampling period through GPIO interrupt; and the collected biometric data is stored in data buffer 80 to ensure data continuity.

[0082] The electronic device provided in this application, through virtual simulation, can not only enhance the target user's immersion in learning traffic safety education content, but also strengthen the user's sense of participation and realism, making traffic safety education more vivid and profound. By updating the target recommended scenarios based on the user's emotional state, it provides personalized traffic safety experience content for the user, which can not only accurately match users with content, avoiding the problem of mismatch between user's actual needs and resources, and improving the accuracy and effectiveness of scenario recommendations, but also improve the user experience and learning effect, and enhance the utilization efficiency of educational resources.

[0083] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
