Description

Technical Field

[0001] The present invention relates to the field of virtual reality (VR) technology, and in particular to a personalized occupant motion sickness relief system and method based on virtual reality. Background Art

[0002] Virtual Reality (VR): Virtual Reality is a general term for virtual scenes and devices developed based on 3D.

[0003] Motion sickness: Motion sickness is a feeling of discomfort caused by movement, which is common when riding in public transportation (such as cars, ships, and airplanes). Symptoms of motion sickness include dizziness, nausea, vomiting, headache, sweating, etc., which may seriously affect an individual's comfort and ability to move.

[0004] With the popularity of self-driving vehicles and long-distance transportation, people often use mobile phones, car screens and other entertainment methods to pass the time in the car. As a potential interactive method, virtual reality (VR) can be widely used in vehicles for casual games, entertainment and more serious immersive applications (such as remote video conferencing). However, improper VR design may aggravate the occurrence of motion sickness.

[0005] When riding in a vehicle, nearly one-third of passengers experience dizziness, pale face, cold sweat, nausea, vomiting and other reactions. We call it motion sickness, which is a disease caused by people being in a moving environment (such as a moving vehicle). Passengers' feelings are directly affected by people, vehicles and the environment. Figure 1 As shown, the main factors are as follows:

[0006] 1. The degree of sensory conflict. That is, the degree of conflict between the human visual organs and the motion perceived by the vestibular system. Road conditions, driving operations, and vehicle properties will determine the vibration input received by passengers in the car, thereby affecting the vestibular perception of motion, and then affecting the degree of motion sickness. According to statistics, more than 70% of people believe that multiple bends / turns, frequent sudden stops and rapid movements will accelerate / aggravate the degree of motion sickness. Increasing visual conflict will also intensify motion sickness symptoms. For example, reading a book or watching a computer screen in a moving vehicle will significantly aggravate motion sickness, and watching moving images (videos) is much less stimulating than watching static content (reading). On the contrary, adequate window views can reduce motion sickness, or the degree of motion sickness of people who look at the road scene outside the window is alleviated compared to those who do not look out the window, especially when looking at the road ahead.

[0007] 2. Environmental comfort. The comfort of the environment will affect a person's state. A comfortable environment will make people more relaxed and less susceptible to motion sickness. Objectively speaking, the comfort of the environment can be evaluated from aspects such as ambient temperature, ambient humidity, air circulation, smell, and seats. Being in an environment with unpleasant smells (leather) will aggravate the symptoms of motion sickness. In addition, a warm and humid environment will make people more prone to motion sickness.

[0008] 3. Personal situation. Individual susceptibility refers to the individual's susceptibility to motion sickness, that is, the individual risk of disease. Through research on the population, it was found that women are more likely to suffer from motion sickness than men. In addition, studies have shown that age is also one of the factors that affect individual susceptibility. Psychologically, psychological factors such as anxiety and tension, fatigue, and lack of concentration may affect the physiological system through neuroendocrine pathways, aggravating or triggering motion sickness. Research by Frank et al. shows that headaches, fatigue, lack of sleep, etc. can also aggravate the degree of motion sickness.

[0009] Existing methods for alleviating motion sickness in virtual reality passengers mostly focus on reducing sensory conflicts. Although this direction has made some progress by simulating car movement and providing visual cues in virtual reality, there is little consideration of individual factors, and there is a lack of personalized settings and the ability to respond to the needs of different passengers.

[0010] It should be noted that the information disclosed in the above background technology section is only used for understanding the background of the present application, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0055] The specific embodiments of the present invention are further described below.

[0056] A personalized passenger motion sickness relief system and method based on virtual reality technology. By collecting the vehicle's motion data (such as speed, acceleration, direction, etc.) in real time and transmitting the data to the virtual reality device, a virtual environment synchronized with the vehicle's motion is generated. The system supports personalized virtual scene selection, scene element customization, personalized motion feedback, and automatic adjustment based on the passenger's physiological state to help passengers relieve motion sickness symptoms.

[0057] Hardware Composition

[0058] Virtual reality equipment: A wearable virtual reality head-mounted display (VR headset), such as the Oculus Quest 3, is used to present virtual scenes. The device needs to be equipped with a high-resolution display and motion sensors to track the passenger's head movement in real time and update the display content.

[0059] Sensor module: including inertial measurement unit (IMU) and global positioning system (GPS) sensors, used to collect vehicle motion data, such as acceleration, angular velocity, direction, speed and location information. IMU is installed inside the vehicle and can monitor the acceleration and steering of the vehicle in real time.

[0060] Physiological monitoring module: This module includes a heart rate monitor, galvanic skin response (GSR) sensor, etc., which is used to monitor the passenger's physiological state, such as heart rate changes, galvanic skin response, etc., to assess their motion sickness symptoms.

[0061] Data processing unit: Built into the virtual reality device or external computing device, it is responsible for processing vehicle motion data and passenger physiological data, generating and adjusting synchronized virtual reality scenes in real time.

[0062] System software design

[0063] Virtual scene generation module: Generates virtual scenes synchronized with actual movement through data collected by vehicle sensors. Virtual scenes can be personalized according to passenger needs, such as natural landscapes, space scenes, or simulated vehicle interior environments. The system also supports the import of scenes developed by third parties.

[0064] Scene element adjustment module: The system supports a personalized interactive interface, and users can adjust the display content according to their own needs, such as adding additional visual information and providing visual clues of vehicle movement (such as navigation data, speed prompts, particles suggesting vehicle movement, etc.).

[0065] Motion feedback control module: According to the real-time motion data of the vehicle (such as acceleration and angular velocity), the motion feedback intensity and synchronization frequency in the virtual scene are adjusted to ensure that the motion perceived by the passengers in the virtual world is consistent with the actual vehicle motion. This module allows users to manually adjust the sensitivity of the feedback to cope with the sensitivity of different passengers to motion sickness.

[0066] Adjustment module based on physiological feedback: The system monitors the physiological feedback of passengers (such as heart rate and skin galvanic response) to determine the motion sickness symptoms of passengers in real time. When the system detects signs of motion sickness such as a fast heart rate, it automatically adjusts the motion feedback in the virtual scene, reduces visual stimulation, and provides a calmer and soothing environment. For example, it slows down the speed of movement in the scene, reduces unnecessary visual complexity in the scene, or switches to a calmer virtual environment.

[0067] System operation process

[0068] 1. Start the system: After entering the vehicle, the passenger wears the VR device and starts the motion sickness relief application. The system first obtains the real-time motion data of the vehicle through the sensor module.

[0069] 2. Personalized selection of virtual scenes: Passengers can choose scenes according to their preferences, such as natural scenery, space scenes, virtual environments inside the car, etc.

[0070] 3. Personalized adjustment of scene elements: Users can adjust the display content according to their own needs, such as navigation information, speed prompts, etc.

[0071] 4. Personalized adjustment of motion feedback: Passengers can adjust the sensitivity of motion feedback based on their personal preferences.

[0072] 5. Physiological feedback monitoring and automatic adjustment: The physiological monitoring module continuously collects the passenger's heart rate and skin electrical response. When the system detects that the passenger may have signs of motion sickness (such as a significant increase in heart rate), the system will automatically adjust the intensity of movement in the virtual scene to reduce the dynamic effect in the virtual environment, or adjust non-motion factors such as sound effects and light to improve comfort. For example, when a passenger feels uncomfortable, the system can automatically switch to a more stable virtual scene, such as a static landscape or a simplified in-car environment, to alleviate the passenger's symptoms.

[0073] 6. End of use: After the trip, the system will analyze the passenger's usage data and provide more personalized motion sickness relief suggestions for subsequent journeys.

[0074] In summary, the present invention proposes a virtual reality system and method for alleviating motion sickness in passengers. By collecting real-time motion data of vehicles, combined with personalized virtual scenes and motion feedback adjustments, personalized scene settings for user experience and automatic adjustment functions based on physiological feedback are provided. Compared with traditional methods, the present invention is a personalized virtual reality system and method for alleviating motion sickness. By selecting personalized virtual scenes, scene elements, setting personalized motion feedback, and automatic adjustment based on physiological feedback, the comfort and experience of passengers are greatly improved. The significant advantages of the present invention are:

[0075] 1. Improved user experience: By providing personalized virtual scenes and motion feedback, the system can better meet the needs of different passengers and improve the comfort of the journey.

[0076] 2. Significant relief of motion sickness: Through personalized content display, motion sickness caused by movement in transportation vehicles can be significantly reduced.

[0077] 3. High scalability: It is not only suitable for various means of transportation (such as cars, airplanes, trains, etc.), but can also be adjusted according to different environments and user needs, and has broad market application potential.
