In-Cabin Visual Media Adjustment for Vehicle Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion sickness in vehicle occupants is a common issue due to mismatched perceived and actual vehicle motion, exacerbated by activities like reading or viewing screens, which existing technologies have not adequately addressed.
Innovation Solution
The technology involves generating motion compensation signals based on detected motion events to adjust display positions or graphics and provide haptic outputs to mitigate motion sickness, using data from various sensors like cameras and LiDAR, and processing this information to preemptively or reactively adjust cabin parameters such as display orientation and seat haptics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual media is displayed in autonomous vehicles, then information delivery and entertainment are improved, but motion sickness in occupants worsens
Solution Approach 1:
The system preemptively adjusts visual media parameters (brightness, contrast, content) before motion events occur based on sensor data predicting upcoming maneuvers. This preliminary adjustment prevents motion sickness before it starts, rather than reacting after symptoms appear.
Solution Approach 2:
The visual media display dynamically adapts its characteristics in real-time based on detected vehicle motion and predicted maneuvers. The system continuously modifies brightness, contrast, and content selection to match current motion conditions, making the display adaptive rather than static.
2Object-affected harmful factors
If display position and graphics are adjusted to reduce motion sickness, then passenger comfort is improved, but device complexity increases
Solution Approach 1:
The system uses existing vehicle sensors (accelerometers, gyroscopes, motion sensors) for multiple purposes: both for autonomous vehicle navigation control and for detecting motion events that cause passenger discomfort. This multi-functionality avoids adding dedicated sensors solely for motion sickness prevention.
Solution Approach 2:
The system automatically detects motion events, selects appropriate visual media adjustments, and applies corrections without requiring manual input from passengers. The entire process is self-regulating, using sensor data to automatically modify display parameters and reduce motion sickness.
3Object-affected harmful factors
If haptic outputs are provided to occupants, then motion sickness mitigation is improved, but energy consumption increases
Solution Approach 1:
Haptic feedback is provided in periodic pulses synchronized with detected motion events rather than continuous operation. The system applies haptic corrections only when motion sickness-triggering events occur, energy-efficiently targeting specific moments rather than constant activation.
