Passenger Motion Sickness Mitigation Through Real-Time Sensory Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motion sickness reduction technologies, such as medications and limited vibration-based detection systems, are ineffective in accurately addressing motion sickness in vehicle passengers due to mismatched sensory inputs, leading to dissatisfaction and temporary confusion.
Innovation Solution
A motion sickness reduction system that collects passenger state information and real-time vehicle data to generate and output motion sickness reduction information through visual and auditory means, including augmented reality videos, gradation changes, and spatial acoustic sounds, to align perceived and actual motion experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If medications such as suspensions and patches are used to reduce motion sickness, then motion sickness symptoms may be suppressed, but side effects increase and effectiveness varies among individuals
Solution Approach 1:
The patent replaces chemical-based motion sickness prevention (medications) with a sensory-based system that uses visual and auditory feedback to provide motion information to the passenger's brain, thereby reducing motion sickness symptoms without the harmful side effects of drugs
Solution Approach 2:
The system introduces an intermediary information processing mechanism that collects sensor data about vehicle motion and delivers processed motion information to the passenger through displays and speakers, acting as a mediator between the actual vehicle motion and the passenger's sensory perception
2Difficulty of detecting and measuring
If vibration-based detection systems are used to detect motion sickness, then detection capability is provided, but measurement accuracy is insufficient
Solution Approach 1:
The patent merges multiple sensor types (acceleration sensors, gyro sensors, vibration sensors) to collect comprehensive vehicle motion data, combining their outputs to achieve accurate motion sickness detection that overcomes the limitations of any single sensor type
Solution Approach 2:
The system uses a multi-functional sensor array that detects various aspects of vehicle motion (acceleration, angular velocity, vibration) simultaneously, enabling the system to accurately characterize complex motion patterns that cause motion sickness
3Device complexity
If there is no visual or auditory feedback of vehicle motion to the passenger, then the system remains simple, but sensory mismatch increases causing motion sickness
Solution Approach 1:
The system implements feedback by continuously monitoring vehicle motion through sensors and providing real-time visual and auditory feedback to the passenger through displays and speakers, creating a closed-loop system that reduces sensory mismatch by informing the brain of actual vehicle motion
Solution Approach 2:
The patent adds new dimensions of information delivery (visual displays and auditory feedback) beyond traditional vibration-only approaches, creating a multi-dimensional sensory feedback system that more comprehensively addresses the sensory mismatch problem

AI summary
A motion sickness reduction system of a passenger of a vehicle includes a state information acquirer to collect state information of the passenger, a behavior information acquirer to collect real-time driving information of the vehicle from a sensor located in the vehicle, a processor to determine a motion sickness state of the passenger based on the collected state information, and generate motion sickness reduction information based on the determined motion sickness state; and an output unit to output the generated motion sickness reduction information. The generated motion sickness reduction information output by the output unit is at least one of visually recognizable by the passenger, auditorily recognizable by the passenger, or a combination thereof.
