Vehicle Seat Control for Virtual Reality Motion Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for operating seat devices in motor vehicles during virtual reality applications fail to effectively reduce the risk of seasickness caused by the superimposition of real and simulated movement or acceleration forces on vehicle occupants.
Innovation Solution
A method that involves a seat device connected to both the motor vehicle's sensors and a virtual reality application's computing unit, which detects real and simulated movement or acceleration values to calculate corrective movements or accelerations, allowing the seat unit to compensate for these forces and align the user's sense of balance with the virtual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seat device compensates for real movement forces during virtual reality application, then the user experience is improved and seasickness is reduced, but the device complexity increases due to integration of sensors and control systems
Solution Approach 1:
The patent combines the seat device with sensor units and control devices to create an integrated system that detects vehicle movement and automatically adjusts seat position to compensate for acceleration forces during virtual reality applications
Solution Approach 2:
The system uses sensor units to detect real acceleration values and feeds this information to the control device, which calculates corrective movements and activates the seat drive accordingly, creating a closed-loop feedback system that continuously adapts to vehicle movement
2Object-affected harmful factors
If the seat device actively compensates for acceleration forces, then seasickness risk is reduced, but the energy consumption increases due to continuous sensor operation and seat adjustment
Solution Approach 1:
The control device is configured to calculate and activate corrective movements based on detected acceleration events, operating periodically rather than continuously, which reduces energy consumption while maintaining effectiveness in compensating for seasickness-causing forces
3Adaptability or versatility
If the corrective movement precisely matches the virtual actual value, then the immersion in virtual reality is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The system dynamically adjusts seat position parameters based on detected acceleration values and virtual reality movement data, changing position, orientation, and movement characteristics in real-time to match the virtual environment and enhance immersion
