Predictive Display Synchronization for Motion Sickness Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers experience varying levels of motion sickness due to conflicting visual and vestibular perceptions during vehicle travel, and existing display methods fail to provide personalized anti-motion sickness solutions effectively.
Innovation Solution
Predict vehicle acceleration and angular velocity with low or no delay to display synchronized visual anti-motion sickness content based on user and vehicle conditions, adjusting display parameters such as direction, speed, and position to reduce perception conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If visual content is displayed during vehicle travel, then entertainment and navigation functions are provided, but visual-vestibular conflict occurs causing motion sickness
Solution Approach 1:
The system performs preliminary actions by predicting future acceleration and angular velocity before the motion occurs. The prediction module forecasts vehicle motion parameters in advance, allowing the display to prepare anti-motion sickness content that will be synchronized with the actual motion, reducing the visual-vestibular conflict before it fully manifests.
Solution Approach 2:
The display content dynamically adapts to individual user characteristics and real-time vehicle motion parameters. The system adjusts display parameters such as motion intensity, direction, and timing based on user sensitivity profiles and predicted acceleration/angular velocity, making the visual content flexible and responsive to changing conditions.
2Reliability
If display content is synchronized with vehicle motion, then motion sickness is reduced, but system delay causes latency between motion detection and content display
Solution Approach 1:
The system compensates for processing delays by performing preliminary prediction of vehicle motion parameters. Instead of reacting to current motion data, the prediction module forecasts future acceleration and angular velocity, allowing the display to show content that will be synchronized with the actual motion the user experiences, effectively hiding the system latency.
Solution Approach 2:
The system applies a predictive buffer that cushions against the inherent delays in the display system. By predicting motion parameters in advance and adjusting the timing of visual content accordingly, the system creates a temporal buffer that ensures visual feedback arrives at the same time as the vestibular sensation, compensating for processing and display latency.
3Reliability
If generic anti-motion sickness content is displayed, then some users experience relief, but personalized needs of different users are not met
Solution Approach 1:
The system applies local quality by tailoring the display content to each user's specific characteristics and sensitivity profile. Different users receive customized visual parameters such as motion intensity, speed, and type of content based on their individual tolerance levels and preferences, rather than a one-size-fits-all approach.
Solution Approach 2:
The anti-motion sickness content dynamically adapts to both user characteristics and real-time vehicle motion conditions. The system adjusts display parameters on-the-fly based on the user's profile and the predicted acceleration and angular velocity, making the solution both personalized and responsive to changing motion scenarios.
