Description

Technical Field

[0001] This invention relates to the technical field of transportation vehicles, specifically to a visual guidance display system and method for preventing motion sickness in passengers. Background Technology

[0002] With the increasing popularity of electric vehicles and the development of autonomous driving technology, passengers are spending more and more time in the car and engaging in non-driving activities (such as reading, working, and watching videos). This passive riding state can easily lead to a conflict between the passenger's visual perception system and vestibular system (inner ear balance perception), thus triggering motion sickness.

[0003] Currently, some technologies have attempted to alleviate motion sickness by adjusting seats, suspension systems, or air conditioning environments. However, these methods mainly rely on physical environmental adjustments and lack active intervention on the passenger's visual system, thus failing to fundamentally solve the motion sickness problem caused by the inconsistency between visual and motion perception. Summary of the Invention

[0022] The following will be combined with the appendix Figure 1 The technical solution of the present invention will be clearly and completely described below. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0023] A visual guidance display system for preventing motion sickness includes a vehicle motion state acquisition module, a passenger perception state monitoring module, a visual guidance pattern generation module, and an augmented reality display device. The vehicle motion state acquisition module acquires real-time motion state data of the vehicle, which can be implemented via an inertial measurement unit (IMU), GPS, CAN bus, etc. The module can collect dynamic parameters such as vehicle acceleration, steering angle, speed, and yaw rate. The passenger perception state monitoring module acquires the perception state data of passengers inside the vehicle, using eye-tracking cameras, facial expression recognition systems, biosensors, etc., to determine whether passengers are prone to motion sickness. The module can observe whether passengers are reading, have their eyes closed, their head posture, heart rate, etc. The visual guidance pattern generation module is connected to the vehicle motion state acquisition module and the passenger perception state monitoring module. This module generates at least one visual guidance pattern matching the current motion state based on the real-time motion state data and the passenger perception state data. The visual guidance pattern includes at least one of the following: a virtual horizon pattern, a motion trajectory line pattern, a dynamic light and shadow pattern, and a visual focus guidance pattern. The augmented reality display device is connected to the visual guidance pattern generation module. The augmented reality display device is used to display the visual guidance pattern in real time, and the motion state of the visual guidance pattern is synchronized with the motion state of the vehicle in real time.

[0024] This application constructs a multi-dimensional visual reference system that is synchronized with the vehicle's posture in real time, including a virtual horizon, motion trajectory line, dynamic light and shadow, and visual focus guidance. This system reconstructs the horizon perception that humans rely on to maintain balance, provides advance warning of the vehicle's motion trajectory, simulates changes in light and shadow in the natural environment, and guides the gaze to shift periodically outward. Before passengers experience motion sickness symptoms, it eliminates the conflict between visual and vestibular perception, thus achieving motion sickness prevention.

[0025] Since people primarily rely on the horizon as a spatial reference frame while in motion, passengers are prone to disorientation and motion sickness when the horizon is not visible, such as when reading inside a car, driving at night, or in a tunnel. Therefore, displaying a virtual horizon pattern inside the vehicle that matches the real horizon helps passengers maintain their sense of space and reduces conflict between the vestibular and visual systems.

[0026] Because passengers lack perception of changes in the external environment, such as the movement of sunlight and changes in shadows, a discrepancy can easily arise between visual stillness and physical movement. Therefore, dynamic light and shadow patterns are generated to simulate changes in light and shadow in the natural environment outside the vehicle, enhancing the consistency between vision and physical movement and reducing motion sickness. Specifically, based on information such as time, weather, geographical location, and lighting angle, dynamic light and shadow changes synchronized with the real environment are generated, projecting simulated sunlight paths, cloud shadows, and tree shadows onto the car windows. The speed of the light and shadow movement is synchronized with the vehicle speed, enhancing the visual sense of following the movement. It is particularly suitable for automatically enhancing light and shadow simulation in low-light scenarios such as tunnels, nighttime, and cloudy days, and offers multiple light and shadow style options, such as natural, technological, and minimalist styles.

[0027] Since passengers lack the expectation of the vehicle's trajectory while inside the vehicle, especially in autonomous driving scenarios, sudden turns or lane changes can cause discomfort. Therefore, projecting motion trajectory patterns can inform passengers of the vehicle's direction of movement in advance by displaying the trajectory line that the vehicle is about to travel, thereby reducing the risk of motion sickness caused by unexpected movements.

[0028] The visual guide pattern generation module includes a virtual horizon generation unit, which is used for: Receive vehicle roll and pitch angle data collected by the inertial measurement unit; Based on the roll and pitch angle data, a horizontal line is generated that is synchronized with the vehicle's attitude in real time. The tilt angle of the horizon is dynamically adjusted according to the vehicle's posture, and the augmented reality display automatically adjusts the transparency of the horizon based on the interior lighting intensity or the passenger's gaze direction. The virtual horizon generation unit uses real-time synchronization with the vehicle's posture to dynamically adjust visual guidance and alleviate motion sickness.

[0029] According to some embodiments of the present invention, the visual guidance pattern generation module includes a motion trajectory line generation unit, which is used for: Based on the vehicle's current speed, acceleration, steering angle, and path planning data, predict the driving path within the next 5 to 10 seconds; The predicted driving path is generated as a trajectory line, which can be a continuous line or a dashed line. The color of the trajectory line changes dynamically based on the prediction confidence level, and the trajectory line is enhanced before turning, changing lanes, or going uphill / downhill. The motion trajectory line generation unit can obtain real-time synchronized trajectory lines to alleviate motion sickness.

[0030] Because passengers often stare at fixed points inside the vehicle, such as books or mobile phone screens, for extended periods, the conflict between visual and bodily motion perception is exacerbated, a significant contributing factor to motion sickness. Therefore, according to some embodiments of the present invention, an adaptive control module is further included to periodically guide the passenger's gaze to shift outwards by periodically displaying guiding visual elements, thereby reducing the risk of motion sickness. The adaptive control module is connected to a passenger perception state monitoring module and a visual guidance pattern generation module, and is used to determine whether the passenger is in a high-risk state for motion sickness based on the passenger's perception state data. A high-risk state for motion sickness includes at least one of the following: reading, screen viewing, and eyes closed. When a passenger is determined to be at high risk of motion sickness, and the passenger has not been looking out the window for an extended period, a visual focus guidance pattern is triggered. The visual guidance pattern generation module automatically activates the corresponding pattern. The pattern can be a light dot, arrow, pulsed circle, text prompt, etc., and appears periodically at different locations outside the window, simulating natural points of attraction such as roadside signs, trees, and streetlights. Perception data can include eye-tracking information to determine if the passenger has not been looking out the window for an extended period, triggering the guidance mechanism. The guidance frequency can be adjusted according to the passenger's individual needs, such as once every 30 seconds or once every 2 minutes.

[0031] When the passenger perception status monitoring module detects that the original visual guidance has failed—that is, the passenger is engrossed in their phone for an extended period and refuses to look out the window—the visual guidance display system takes the next step. The visual guidance pattern generation module further enhances the brightness and color saturation of the visual guidance pattern and adds a flashing effect. The passenger perception status monitoring module determines whether this has attracted the passenger's attention. If it still determines that the passenger is continuing to be engrossed in their phone, it controls the vehicle's audio playback module to play a voice reminder, and simultaneously automatically dims the windows or turns on the vehicle's lighting module, allowing the passenger to perceive the change in light. Under the combined effect of the light change, voice reminder, and visual guidance pattern, the system encourages the passenger to look out the window. Specifically, dimming the windows during the day creates a sudden darkness in the surrounding environment, while turning on the lighting module at night brightens the environment. Visual guidance primarily guides passengers to look out the window subtly, minimizing disturbance and improving passenger comfort. Voice reminders and changes in light, on the other hand, are more disruptive to passengers, so they are only triggered when visual guidance is ineffective. This approach improves passenger comfort while ensuring effective reminders in special circumstances.

[0032] According to some embodiments of the present invention, the augmented reality display device includes at least one of the following: Augmented reality car windows utilize transparent OLED or projection display technology; Head-up display, located on the vehicle's windshield; Smart glasses or augmented reality glasses, suitable for rear-seat passengers; The presentation of visual guidance patterns on different display devices is adaptively adjusted according to the physical characteristics of the display device and the passenger's position.

[0033] In some embodiments, rear passengers wear dedicated augmented reality glasses, and the visual guidance display system generates dynamic visual guidance based on the vehicle's motion. Alternatively, the vehicle's trajectory lines are displayed in the HUD area on the windshield to help passengers predict vehicle movement; before sudden braking or sharp turns, the trajectory lines change color or flash to alert passengers to the impending change.

[0034] Reference Figure 1 A visual guidance display method for preventing motion sickness in passengers includes the following steps: Step S100: Obtain real-time motion status data of the vehicle; Step S200: Acquire the perception status data of passengers inside the vehicle; Step S300: Based on the vehicle's real-time motion state data and perception state data, generate at least one visual guidance pattern that matches the current motion state. The visual guidance pattern includes at least one of the following: Virtual horizon pattern, used to construct a spatial reference line in the in-vehicle display area that is synchronized with the actual horizon posture; Motion trajectory lines are used to display the vehicle's expected travel path; Dynamic light and shadow patterns are used to simulate changes in light and shadow in the natural environment outside the vehicle; Visual focus guiding patterns are used to periodically direct passengers' gaze toward the outside of the vehicle; Step S400: The visual guidance pattern is displayed in real time on the vehicle display device, and the movement state of the visual guidance pattern is synchronized with the movement state of the vehicle in real time.

[0035] This application constructs a multi-dimensional visual reference system that is synchronized with the vehicle's posture in real time, including a virtual horizon, motion trajectory line, dynamic light and shadow, and visual focus guidance. This system reconstructs the horizon perception that humans rely on to maintain balance, provides advance warning of the vehicle's motion trajectory, simulates changes in light and shadow in the natural environment, and guides the gaze to shift periodically outward. Before passengers experience motion sickness symptoms, it eliminates the conflict between visual and vestibular perception, thus achieving motion sickness prevention.

[0036] According to some embodiments of the present invention, the steps for generating a virtual horizon pattern include: The vehicle's roll and pitch angles are obtained through an inertial measurement unit; Based on the roll and pitch angles, draw a horizontal line in the display area that is synchronized with the vehicle's attitude in real time. The tilt angle of the horizon line is dynamically adjusted according to the vehicle's posture, and its transparency is automatically adjusted based on the interior lighting intensity or the passenger's gaze direction. For example, a transparent OLED window can be used to display a dynamic virtual horizon line on the passenger-side glass. The system incorporates IMU sensor data to ensure that the displayed pattern is synchronized with the vehicle's movement. When the vehicle turns, the horizon line automatically tilts to maintain consistency with the vehicle's actual posture. This embodiment helps passengers maintain a sense of space and reduces conflict between the vestibular and visual systems by displaying a virtual horizon line that matches the real horizon line inside the vehicle.

[0037] According to some embodiments of the present invention, the steps for generating a motion trajectory line pattern include: Based on the vehicle's current speed, acceleration, steering angle, and path planning data, predict the driving path within the next 5 to 10 seconds; The predicted driving path is drawn as a trajectory line in the display area. The trajectory line can be a continuous line or a dashed line. The color of the trajectory line changes dynamically based on the prediction confidence level of the trajectory line, and the trajectory line is enhanced before turning, changing lanes, or going uphill or downhill.

[0038] By displaying the vehicle's upcoming trajectory, passengers are informed in advance of the vehicle's direction of movement, reducing the risk of motion sickness caused by unexpected movements.

[0039] According to some embodiments of the present invention, it further includes: Determine whether a passenger is at high risk of motion sickness based on the passenger's perception status data. High risk of motion sickness includes at least one of the following: reading, watching a screen, and closing one's eyes. When a passenger is determined to be at high risk of motion sickness, the corresponding visual guidance pattern is automatically activated. The visual focus guidance pattern is triggered when the passenger does not look out of the vehicle for an extended period of time. The visual focus guidance pattern includes at least one of the following: a light spot, an arrow, a pulsed circle, or a text prompt.

[0040] Based on vehicle status and passenger perception data, visual guidance is dynamically adjusted. When a passenger is determined to be at high risk of motion sickness, visual guidance patterns are periodically displayed to guide the passenger's gaze to periodically shift out of the vehicle, reducing the risk of motion sickness. The guidance frequency is adjustable and can be adjusted according to passenger needs, such as once every 30 seconds or once every 2 minutes. This method provides special visual guidance patterns for passengers prone to motion sickness, further reducing the likelihood of motion sickness.

[0041] According to some embodiments of the present invention, it further includes: determining the degree of motion sickness of a passenger based on biosignature information in the passenger's perception state data, wherein the biosignature information includes at least one of heart rate, blood oxygen, blood pressure, and body impedance; When the degree of motion sickness exceeds a preset threshold, adjust the display parameters of the visual guidance pattern, including at least one of transparency, brightness, display frequency, or pattern style; The display delay of the visual guide pattern is less than 100 milliseconds.

[0042] By determining the severity of motion sickness in passengers using biometric information, the display effect of visual guidance patterns can be adjusted more promptly and accurately, resulting in better guidance and prevention of motion sickness.
