Description

Technical Field

[0001] The present invention relates to the field of motion sickness prevention and treatment, and in particular to a multi-modal motion sickness prevention device. Background Art

[0002] Motion sickness (also known as "motion sickness," "motion sickness," or "motion sickness") is a physiological reaction mainly caused by conflicts in the vestibular-visual-proprioceptive systems. It covers typical scenarios such as motion sickness, seasickness, airsickness, and disembarkation sickness. Its high incidence (according to WHO statistics, about 30% of the population has moderate or above susceptibility) and long-term health effects (such as vestibular function degeneration and spatial cognitive impairment) have become major challenges in the global public health field.

[0003] Current methods for preventing and treating motion sickness mainly focus on the following technical approaches, but all of them have significant limitations:

[0004] 1) Physical adaptability training: Improving the tolerance threshold through systematic vestibular function training (such as rotary chair training and centrifuge exposure). Although it is a standard training program for professional groups such as astronauts and pilots, it has shortcomings such as a long training cycle (usually 6-12 months), strong equipment dependence, and large individual differences, making it difficult to popularize in the general public.

[0005] 2) Drug intervention: Oral antihistamines (such as dimenhydrinate) or transdermal patches (such as scopolamine) relieve symptoms by inhibiting central nervous system excitability, but are accompanied by side effects such as drowsiness, dry mouth, and blurred vision. Long-term use may lead to drug dependence and compensatory damage to vestibular function.

[0006] 3) External treatment of Traditional Chinese Medicine: Although non-invasive methods such as acupoint pressing (such as Neiguan acupoint wristband) and Chinese medicine plasters (such as ginger plasters on the navel) are easy to operate, they lack quantitative physiological indicator monitoring and personalized stimulation parameter control, and the clinical efficacy is less than 40% (according to the 2021 statistics of the "Journal of External Treatment of Traditional Chinese Medicine").

[0007] 4) Small device intervention: Direct current stimulation is used, specifically by applying microcurrent (1-2 mA) through skin electrodes in the vestibular area. However, this has not been widely adopted due to the risk of electrochemical burns (sudden changes in pH at the electrode-skin interface) and the difficulty in dynamically matching stimulation parameters.

[0008] 5) Hydrodynamic visual adjustment: Anti-dizziness glasses that have appeared in recent years simulate motion visual feedback by shaking liquid in a closed cavity. However, they have problems such as high response delay (>500ms) and poor scene adaptability (only effective for shaking of a specific frequency), and their anti-dizziness effect is limited.

[0009] In addition, the inventor has searched and found that the current anti-sickness devices for treating motion sickness include the following:

[0010] Publication No. CN110208949A discloses a VR device that uses electrical stimulation to reduce the feeling of dizziness when wearing. In this patent application, it mainly includes a VR glasses body, wherein the VR glasses body is mainly composed of a glasses shell and a mobile device fixing box, wherein the glasses shell is a hollow box-shaped structure, wherein the front surface and the rear surface of the glasses shell are respectively provided with an objective lens embedding opening and an eyepiece embedding opening. The present invention generates a pulse electric signal through an electronic anti-sickness device, and sticks the patch electrodes of the electronic anti-sickness device to the back side of the ears. The pulse electric signal offsets or weakens the excessive bioelectricity generated by the vestibule due to excessive movement stimulation of the human body, reduces and prevents the vestibular nerve impulses from being transmitted to the central nervous system, which can effectively reduce the feeling of dizziness generated during the wearing of the device. At this time, for application developers who wear the device for a long time, such a structure reduces discomfort, and the use of physical principles can reduce the side effects of drugs.

[0011] Publication number CN205215942U discloses a negative ion anti-sickness device. In this patent application, it includes a main body shell, a battery, a charge and discharge control panel, a negative ion generator, and a main body switch. An earphone cable is provided outside the main body shell. One end of the earphone cable is connected to the negative ion generator inside the main body shell, and the other end of the earphone cable is connected to the earphone. The negative ion potential is directly located and sent to the vestibule of the human ear through the earphone to achieve the treatment purpose.

[0013] Lack of multimodal perception: Head movement, physiological signals, and environmental parameters are not monitored synchronously, resulting in a lack of real-time intervention strategies;

Specific technical effects include the following:

[0027] 1. This invention utilizes a head motion tracking unit and a physiological signal monitoring unit within a multimodal sensor array to simultaneously monitor head motion, physiological signals, and environmental parameters.

[0045] Example 1: Please refer to Figure 1 The present invention provides a technical solution: a multimodal anti-sickness device, including a wearable carrier 1, a restraining component 2 and a full-field wide-angle lens 3.

[0046] See also Figure 2 In this embodiment, the wearable carrier 1 is a mirror-type carrier, which has a light-shielding frame 101 and a power supply, a main control, a full-view integrated or separate wide-angle optical display component 102, a multimodal sensor array 103 and a connection port embedded in the light-shielding frame 101. The light-shielding frame 101 is a flat frame with a nose support or an arc-shaped frame that fits the forehead. The full-view integrated or separate wide-angle optical display component 102 includes a lens-type display screen and an interpupillary distance adjustment unit. The surface of the lens-type display screen is provided with an electrochromic coating. The lens-type display screen is driven by the interpupillary distance adjustment unit to achieve dynamic viewing distance compensation and coordinated adjustment of the field of view angle; the multimodal sensor array 103 includes a head motion tracking unit and a physiological signal monitoring unit, wherein the head motion tracking unit includes at least a UWB ultra-wideband locator and a nine-axis inertial sensor (model MPU-9250 can be selected), and the physiological signal monitoring unit includes at least a forehead PPG sensor (model MAX30102 can be selected) and a nose bridge temperature sensor (model TMP117 can be selected).

[0047] In this embodiment, the restraint member 2 is worn on the user's head and carries the wearing carrier 1. The restraint member 2 includes a front bracket 201 and a restraint unit 202. The lower end of the front bracket 201 is connected to the light-shielding frame 101 of the wearing carrier 1. A full-field wide-angle lens 3 is arranged in the middle of the front bracket 201, and a breathing indicator light 203 is arranged at the upper end of the front bracket 201. The restraint unit 202 is arranged on the rear side of the front bracket 201. The restraint unit 202 is an elastic restraint belt or a locking restraint bracket. The restraint unit 202 is provided with an audio output module 204, and the audio output module 204 is an earphone or a micro speaker.

[0048] Example 1 discloses a multimodal anti-sickness device, which, through the arrangement of a mirror-type wearable carrier 1 and a restraining member 2, realizes all-round accurate monitoring and personalized and efficient intervention of the user's dizziness in a complex riding environment.

[0049] Specifically, the mirror-type wearable carrier 1 is not only ergonomically designed to provide users with a comfortable and stable wearing experience, but also integrates a multimodal sensor array 103. The array includes a head motion tracking unit (equipped with a UWB ultra-wideband locator and a nine-axis inertial sensor IMU) and a physiological signal monitoring unit (including a forehead PPG sensor and a nose bridge temperature sensor). These units can accurately obtain the user's head motion status and multiple key physiological indicators in real time, providing rich and accurate data support for a comprehensive understanding of the user's physical condition. The restraint member 2 ensures that the wearable carrier 1 is firmly fixed on the user's head through the rational combination of the front bracket 201 and various forms of restraint units 202. At the same time, the full-view wide-angle lens 3 set on the front bracket 201 can collect information about the internal and external environments of the vehicle, and integrate it with the data collected by the multimodal sensor array 103, further enriching the system's perception of the scene. Coupled with the integration of the audio output module 204, the anti-sickness device can provide users with personalized anti-sickness intervention measures based on user status and environmental information through multi-channel feedback such as vision and hearing, effectively alleviating or preventing dizziness and discomfort during the ride, and significantly improving the user's riding experience.

[0050] Example 2: Please refer to Figure 1The present invention provides a technical solution: a multimodal anti-sickness device, comprising a wearable carrier 1, a restraining member 2, and a full-view wide-angle lens 3. In this embodiment, the wearable carrier 1 is a mirror-type carrier, comprising a light-shielding frame 101 and a power supply, a main control, a full-view integrated or separate wide-angle optical display assembly 102, a multimodal sensor array 103, and a connection port embedded inside the light-shielding frame 101. The light-shielding frame 101 is a flat frame with a nose and face support or an arc-shaped frame that fits the forehead. The full-view integrated or separate wide-angle optical display assembly 102 includes a lens-type display screen, which includes but is not limited to an integrated lens (single-piece design) and a split lens (independent left and right eye design). The lens-type display screen is used to display, but is not limited to, reality, virtual reality (VR), augmented reality (AR), and mixed reality (MR) information, and can select and switch between multiple display modes.

[0051] In this embodiment, the lens-type display screen deeply integrates virtual reality technology. Through built-in high-precision gyroscopes, accelerometers, magnetometers and other sensors, the vehicle's motion state can be perceived in real time and accurately, including acceleration, deceleration, turning, bumps, etc. Based on these perception data, the main control will quickly transmit the reality, call the pre-stored virtual scene model, or generate a virtual scene that matches it in real time. For example, when the vehicle accelerates, the display screen (VR lens) will present a realistic or dynamic virtual picture accelerating forward, such as the scenery on both sides of the road quickly passing by backward, so that the user's visual system is highly synchronized with the actual movement of the vehicle. This synchronization can effectively reduce the dizziness caused by the inconsistency between the visual and vestibular system information, and create a relatively stable visual environment for the user.

[0052] VR technology also offers users a rich variety of virtual scenes to choose from. In addition to basic scenes that match the vehicle's motion, users can also choose from a variety of themed scenes based on their preferences, such as a tranquil seaside, a lush forest, or the vast universe. These virtual scenes not only distract users, alleviating boredom and anxiety during the ride, but also regulate their physiological state through visual stimulation, further alleviating symptoms of vertigo.

[0053] Finally, the VR lenses also feature a special anti-vertigo design. By optimizing the light refraction path and reducing the frequency of screen flickering, it effectively reduces visual fatigue and dizziness that may be caused by long-term use. Even when worn for long periods of time, users can maintain a comfortable state without visual discomfort affecting the user experience. Moreover, the VR lenses have excellent light transmittance and anti-reflection properties. While ensuring sufficient light enters the eyes, it minimizes interference from external light and reflected light on the lens surface, further improving image clarity and visibility, ensuring that users can obtain high-quality visual effects under different ambient light conditions.

[0054] Example 3: Please refer to Figure 3 、 Figure 4 The present invention provides a technical solution: a multimodal anti-sickness device, including a wearable carrier 1, a restraining component 2, a full-field wide-angle lens 3 and an electrode component 4.

[0055] See also Figure 2 、 Figure 5 In this embodiment, the wearing carrier 1 is a mirror-type carrier, which has a shading frame 101 and a power supply, a main control, a full-field integrated or separate wide-angle optical display component 102, a multimodal sensor array 103 and a connection port embedded in the inner side of the shading frame 101. The restraint component 2 is worn on the user's head and carries the wearing carrier 1. The restraint component 2 includes a front bracket 201 and a restraint unit 202. The electrode assembly 4 is detachably mounted on the restraint unit 202. The electrode assembly 4 includes a storage compartment 401, an elastic energy storage element, an electrode wire 402, and an electrode patch 404. The front side of the storage compartment 401 is provided with at least three slots 403 arranged side by side, and the elastic energy storage element is arranged in the storage compartment 401. The slot 403 is provided with a perforation in the middle, and the slot 403 is a magnetic slot. The back of the electrode patch 404 is adsorbed and connected to the magnetic slot. The electrode wire 402 on the back of the electrode patch 404 passes through the perforation in the middle of the slot 403 and is wrapped around the outside of the elastic energy storage element. The electrode assembly 4 is connected to the restraint unit 202 by means of a snap, magnetic attraction, or the like. The electrode assembly 4 is connected to the connection port on the wearable carrier 1 via a connecting wire.

[0056] See also Figure 3 In this embodiment, a wireless transmitter (not shown in the figure) and a wired transmitter are provided in the wearable carrier 1. The wireless transmitter is a three-mode fusion communication module based on WiFi, Zigbee and 5G, and the wired transmitter is a data transmission cable 5. The rear end of the data transmission cable 5 is arranged in a ring shape along the constraint unit 202 and the front bracket 201. The signal output end of the data transmission cable 5 is connected to the main control of the wearable carrier 1, and the signal input end of the data transmission cable 5 is provided with a plug connected to the audio and video transmission port.

[0057] Example 3 discloses a multimodal anti-sickness device, which realizes personalized stimulation intervention for the user and diversified expansion of the anti-sickness device functions through an electrode component 4 that can be flexibly disassembled and has a skin stimulation function.

[0058] Specifically, the electrode component 4 can be detachably mounted on the constraint unit 202, and a plurality of magnetic suction grooves distributed side by side are provided on the front side of the storage compartment 401 thereof, which cooperate with the elastic energy storage element and the electrode wire 402 so that the electrode patch 404 can be conveniently adsorbed and installed and the wire can be automatically and neatly stored. This design allows users to quickly store it according to actual needs. The electrode patch 404 can output an electrical stimulation signal of a specific frequency and intensity according to the instructions issued by the main control system to moderately stimulate the user's skin. This stimulation can regulate the human body's nerve conduction and physiological functions, such as affecting the signal transmission of the vestibular system of the inner ear, thereby effectively alleviating dizziness caused by sports scenes such as riding in a car, and realizing personalized anti-dizziness intervention. At the same time, the electrode component 4 is flexibly connected to the constraint unit 202 through various methods such as snaps and magnetic suction.

[0059] In combination with the above-mentioned embodiment 1, embodiment 2, and embodiment 3, the present invention further provides the operating principle of a multi-modal anti-sickness device in different scenarios:

[0060] 1) Riding scenario:

[0061] 1.1) Multimodal Perception and Data Acquisition: When the user puts on the multimodal anti-sickness device and turns it on, the multimodal sensor array 103 immediately starts working. The UWB ultra-wideband locator in the head motion tracking unit uses its high-precision positioning capability to obtain real-time information on the position of the user's head in three-dimensional space. The nine-axis inertial sensor accurately captures the movement of the head, such as acceleration, deceleration, and turning, by measuring parameters such as acceleration and angular velocity. The forehead PPG sensor in the physiological signal monitoring unit uses photoplethysmography to continuously monitor the user's heart rate, blood oxygen saturation and other physiological indicators. The nose bridge temperature sensor senses temperature changes in the user's nose bridge in real time. This temperature data can help determine the user's physical condition and emotional fluctuations. At the same time, the full-field wide-angle lens 3 begins to collect environmental image information inside and outside the vehicle, providing more comprehensive scene data to the main control system.

[0062] During specific implementation, the multimodal anti-sickness device can also be connected to the in-vehicle driving recorder or the external camera to communicate and receive video information in real time to perform multi-dimensional and accurate scene perception and dizziness intervention strategy optimization. Specifically, by receiving video information from the in-vehicle driving recorder or the external camera in real time, the multimodal anti-sickness device can obtain richer and more comprehensive vehicle surrounding environment data. These video information and the data collected by the multimodal sensor array 103 are mutually integrated and mutually verified. For example, when the head motion tracking unit detects that the user's head is turning to the left, combined with the real-time image of the road on the left side of the vehicle taken by the external camera, the main control system can more accurately judge the user's visual focus and the actual road conditions on the left side of the vehicle. If there are other vehicles approaching quickly on the left side of the vehicle at this time, the system can perceive potential risk factors in advance and comprehensively assess the risk of dizziness or nervousness in the user based on the user's physiological signal monitoring data (such as increased heart rate, changes in blood oxygen saturation, etc.). Based on these fused data, the multimodal anti-sickness device can further optimize the dizziness intervention strategy. In terms of optical display, the lens display can dynamically adjust the display content based on real-time video information and the user's head movement status. When the vehicle turns, the main control system combines the images of the turning road captured by the external camera with the user's visual display to present a visual scene that matches the actual turning situation, enhancing the consistency of visual and vestibular system information and reducing dizziness. At the same time, the electrochromic coating can adjust the display brightness in real time based on changes in ambient light in the video information, ensuring a clear and comfortable viewing experience under various lighting conditions.

[0063] 1.2) Data Analysis and Dizziness Risk Assessment: The main control unit receives various data from the multimodal sensor array 103 and the full-view wide-angle lens 3 and applies algorithms for analysis and processing. For head movement data, the main control system compares it with the head movement model of a normal passenger to determine whether there is abnormal shaking or excessive movement. For example, when the vehicle is driving normally, the user's head should maintain a relatively stable state. Frequent and violent head shaking may indicate that the user is about to experience dizziness. For physiological signal data, the main control system analyzes the changing trends of indicators such as heart rate and blood oxygen saturation. If the heart rate suddenly increases or the blood oxygen saturation decreases, combined with the head movement data, the likelihood of dizziness is further assessed. Environmental image information is used to analyze the vehicle's motion status, such as the intensity of acceleration, deceleration, and turning movements, as well as the impact of factors such as interior lighting and space on the user's vision. By integrating these multi-dimensional data, the main control system accurately assesses the user's risk level of dizziness in the current passenger scenario.

[0064] 1.3) Personalized Intervention Strategy Development and Implementation: Based on the vertigo risk assessment results, the system develops a personalized intervention strategy. If the risk level is low, the main control system primarily performs adjustments through the full-field integrated or detachable wide-angle optical display assembly 102. The lens-type display screen is driven by the interpupillary distance adjustment unit, which achieves dynamic viewing distance compensation and coordinated adjustment of the field of view angle based on the user's interpupillary distance and current head movement state. For example, when the vehicle turns, the system adjusts the display content of the lens-type display screen to better match the visual information with the motion state perceived by the vestibular system, reducing the feeling of vertigo caused by the inconsistency between visual and vestibular system information. At the same time, the electrochromic coating on the surface of the lens-type display screen adjusts the display effect according to changes in ambient light, such as reducing the display brightness in strong light environments and increasing the brightness in low light environments, providing the user with a clear and comfortable visual experience. If the risk level is high, the system activates the electrode component 4 for electrical stimulation intervention. The electrode component 4 is detachably mounted on the restraint unit 202, and the electrode patch 404 is connected in a specific manner. The system flexibly adjusts stimulation parameters, such as intensity, frequency, and duration, based on the user's sensitivity threshold and current physical condition, as determined by multimodal data analysis. For example, for users with higher sensitivity, lower intensity electrical stimulation is used; for users experiencing more severe vertigo, the intensity and frequency are appropriately increased. Electrical stimulation acts on the body through specific acupuncture points, regulating the function of the nervous system and alleviating vertigo symptoms.

[0065] In addition, the audio output module 204 (earphone or micro speaker) on the constraint unit 202 can play specific audio signals according to the intervention strategy, such as soothing music, white noise or sound waves with specific frequencies, to further help the user relax and reduce dizziness.

[0066] It is worth noting that during the intervention process, the multimodal sensor array 103 continuously collects the user's head movement, physiological signals, and environmental data, and feeds this data back to the main control unit in real time. Based on this feedback information, the main control unit dynamically evaluates the intervention effect. If the user's dizziness symptoms are alleviated, the main control system gradually reduces the intervention intensity until it stops. If the dizziness symptoms do not improve or worsen, the main control system promptly adjusts the intervention strategy, such as increasing the electrical stimulation intensity, changing the optical display parameters, or adjusting the audio signal, to ensure the effectiveness and timeliness of the intervention.

[0067] 2) Navigation scene:

[0068] 2.1) Initial stage of voyage: When the ship sets sail, the swaying of the hull and the change in acceleration will stimulate the human vestibular system and easily cause dizziness. The multimodal sensing array starts working, the head motion tracking unit monitors the swaying and acceleration of the head, and the physiological signal monitoring unit records the user's heart rate, breathing rate and other physiological indicators. The full-field wide-angle lens 3 collects environmental information inside the cabin and on the deck, such as the size of the waves, the tilt angle of the hull, etc. After analyzing the data, the main control unit assesses the risk of dizziness. The full-field integrated or separate wide-angle optical display component 102 adjusts the display content of the lens-type display screen according to the swaying of the hull, so that the visual information is coordinated with the body's swaying sensation. The electrode component 4 applies appropriate electrical stimulation according to the individual differences of the user, regulates the function of the nervous system, and reduces the burden on the vestibular system. The audio output module 204 plays natural sound effects such as the sound of waves to create a comfortable environment and help the user relax.

[0069] 2.2) During the voyage: During the voyage of the cruise ship, the hull will continue to sway with the fluctuation of the waves. The sea conditions in different sea areas are different, and the amplitude and frequency of the swaying are also different. The multimodal perception system monitors the user's head movement, physiological signals and environmental changes in real time. If it is detected that the user's head shaking intensifies or the physiological indicators are abnormal, the system determines that the risk of dizziness has increased. At this time, the full-field integrated or separate wide-angle optical display component 102 dynamically adjusts the viewing distance compensation and field of view to adapt to the constant shaking of the hull. The electrode component 4 flexibly adjusts the electrical stimulation parameters according to real-time data to ensure the intervention effect. The audio output module 204 selects appropriate audio content for playback according to the user's emotional state, such as relaxing music or voice prompts guiding relaxation.

[0070] 2.3) When encountering wind and waves: When the ship encounters wind and waves and the hull shakes violently, the multimodal perception system responds quickly. The head motion tracking unit accurately captures the violent swings and acceleration changes of the head, and the physiological signal monitoring unit closely monitors the sharp fluctuations of the user's physiological indicators such as heart rate and blood pressure. The full-view wide-angle lens 3 promptly obtains environmental information around the hull, such as the height and direction of the waves. The main control unit formulates a strong intervention strategy. The full-view integrated or separate wide-angle optical display component 102 adjusts the display effect to the maximum extent, reducing the inconsistency between the visual and vestibular system information. The electrode component 4 increases the intensity and frequency of electrical stimulation to quickly relieve excessive stimulation of the vestibular system. The audio output module 204 plays a strong calming audio signal to help the user stay calm and reduce dizziness and discomfort. At the same time, the system continuously monitors the intervention effect and adjusts the strategy in real time based on user feedback to ensure that the user can maintain a relatively comfortable state even in harsh sea conditions.
