Infotainment Feedback for Passenger Motion Sickness Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively counteract motion sickness in motor vehicle passengers by providing timely and relevant feedback to drivers on their driving style, which is crucial for preventing such discomfort.
Innovation Solution
A method that utilizes a motor vehicle infotainment system to load and evaluate datasets on vehicle movements and passenger activities, using a transfer function with a threshold value to generate an equilibrium metaphor visualization, providing feedback to drivers through displays or data glasses to adjust their driving style and prevent motion sickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feedback is provided to the driver about passenger movements, then motion sickness can be counteracted, but the system complexity increases
Solution Approach 1:
The system continuously monitors passenger movements via sensors and provides real-time visual feedback to the driver through the infotainment system. The transfer function processes sensor data to generate equilibrium metaphors that show the relationship between vehicle movements and passenger stability, enabling the driver to adjust driving behavior to prevent motion sickness
Solution Approach 2:
The infotainment system is utilized for multiple purposes: it displays navigation, media, and now also serves as the feedback interface for motion sickness prevention. The existing display and processing capabilities of the infotainment system are leveraged to avoid adding separate dedicated hardware, thereby reducing overall system complexity
2Reliability
If real-time monitoring of passenger movements is implemented, then motion sickness can be prevented, but energy consumption increases
Solution Approach 1:
Instead of continuous high-frequency monitoring, the system uses periodic evaluation of passenger movement data combined with vehicle acceleration data. The transfer function processes these data streams at intervals to update the equilibrium metaphor display, reducing the computational load and energy consumption while maintaining effective motion sickness prevention
Solution Approach 2:
The system leverages existing vehicle sensors (accelerometers, gyroscopes) and the infotainment system's processing capabilities to perform the monitoring and evaluation functions, avoiding the need for additional dedicated power-intensive hardware. The equilibrium metaphor visualization uses the existing display refresh rates of the infotainment system

AI summary
The disclosure relates to a motor vehicle that loads a motor vehicle movement dataset (KBD) indicative of accelerations of the motor vehicle, loads a passenger movement dataset (PBD) indicative of movements of a passenger of the motor vehicle, evaluate the motor vehicle movement dataset (KBD) and the passenger movement dataset (PBD) by means of a transfer function with a predetermined threshold value (SW) in order to generate an image dataset (BS) for an infotainment system of the motor vehicle, and outputs the image dataset (BS) by means of the infotainment system.
