Virtual Content Evaluation System for Motion Sickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating virtual content in motor vehicles do not effectively identify and address issues such as premature termination of playback, which can be due to factors like motion sickness or user dissatisfaction, limiting the ability to optimize content for different routes and user types.
Innovation Solution
A system and method where data on the route traveled, virtual content played, and occupant states are transmitted to a server for evaluation when playback is interrupted, allowing for comprehensive analysis of usage patterns and user feedback to optimize virtual content, including tracking nausea-inducing movements and user ratings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual content is displayed to vehicle occupants during travel, then user engagement and entertainment value are improved, but motion sickness and simulator sickness occur leading to premature playback termination
Solution Approach 1:
The system continuously monitors playback status and detects premature terminations, then feeds this information back to servers for analysis. By tracking which content causes interruptions and under what conditions, the system learns to optimize content selection and delivery to prevent motion sickness while maintaining user engagement.
Solution Approach 2:
The system analyzes various parameters including route characteristics, content properties, and user states to identify patterns leading to premature termination. By changing content parameters (type, duration, intensity) or playback parameters based on route and user data, the system reduces motion sickness while preserving entertainment value.
2Measurement precision
If data on route, content, and user states is collected and transmitted to external servers for evaluation, then comprehensive analysis capability is improved, but system complexity and data processing requirements increase
Solution Approach 1:
External servers act as intermediaries that handle the complex data processing and analysis tasks. The vehicle systems collect and transmit data, but the heavy lifting of comprehensive evaluation is performed by dedicated server infrastructure, allowing precise analysis without burdening the vehicle systems with excessive complexity.
Solution Approach 2:
The evaluation system is segmented into distributed components: data collection in vehicles, data transmission networks, and analysis servers. This segmentation allows each component to be optimized independently, achieving high measurement precision through specialized servers while keeping individual vehicle system complexity manageable.
3Adaptability or versatility
If playback interruption data is transmitted to servers for evaluation, then content optimization capability is improved, but data transmission overhead and processing time increase
Solution Approach 1:
The system collects and pre-processes data locally in vehicles before transmission, organizing playback interruption data with associated metadata (route, content, user state) in advance. This preliminary action reduces the processing burden on servers and enables faster overall evaluation and optimization cycles.
Solution Approach 2:
The system implements continuous feedback loops where playback interruption data is rapidly transmitted and analyzed, with optimization results fed back to improve content delivery. This iterative feedback process enables efficient adaptation of content strategies without requiring excessive processing time at any single stage.
