In-Car VR Scene Synchronization for Unpredictable Vehicle Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-car VR experiences face challenges in creating a consistent and credible virtual experience due to unpredictable vehicle stops, which disrupt immersion and can cause simulator sickness.
Innovation Solution
A method and control device that determine potential stopping points of a vehicle and synchronize virtual scene staging with the vehicle's deceleration, ensuring a convincing and immersive virtual experience by explaining the stopping process within the virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle stops unpredictably during VR experience, then the vehicle can respond to real-world traffic situations, but the virtual experience consistency is disrupted and immersion is broken
Solution Approach 1:
The system performs preliminary actions by predicting potential stopping points before the vehicle actually stops. Virtual scene staging is prepared in advance and triggered when the vehicle decelerates toward these predicted points, ensuring the virtual environment is ready to explain the stopping before it occurs, thus maintaining immersion consistency.
Solution Approach 2:
The patent introduces an intermediary mechanism - the virtual scene staging - that mediates between the physical vehicle stopping and the virtual experience. This intermediary virtual scene acts as an explanation for the stopping, bridging the gap between real-world traffic requirements and virtual environment consistency.
2Reliability
If the vehicle decelerates abruptly for traffic reasons, then traffic safety is ensured, but simulator sickness is caused and user comfort deteriorates
Solution Approach 1:
The patent converts the harmful effect of abrupt deceleration (which causes simulator sickness) into a beneficial opportunity for enhanced virtual storytelling. By triggering virtual scene staging at predicted stopping points, the system transforms unavoidable vehicle stops into engaging virtual narrative moments, thereby converting a harmful disruption into a beneficial immersive experience.
3Ease of operation
If virtual scene staging is added to explain vehicle stopping, then user immersion is enhanced and simulator sickness is reduced, but system complexity increases
Solution Approach 1:
The control device integrates multiple functions into a single system: it predicts stopping points, triggers virtual scene staging, and coordinates with vehicle movement data. This multi-functional approach consolidates what would otherwise require separate systems, managing complexity while delivering enhanced immersion and reduced simulator sickness.

AI summary
A display device that can be worn on the head of a vehicle occupant of a motor vehicle is controlled to display a virtual environment within which the vehicle occupant wearing the display device virtually moves according to a detected movement of the motor vehicle. A potential stopping point of the motor vehicle is determined. A deceleration of the motor vehicle is detected within a given environment of the potential stopping point and the display device is controlled to output a virtual scene staging within the virtual environment which causes a deceleration of the virtual movement of the vehicle occupant within the virtual environment corresponding to the deceleration of the motor vehicle.
