Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices fail to effectively reduce motion sickness in vehicle passengers by not accurately correlating vehicle acceleration with the modification of displayed content, particularly when the device's orientation is not considered.
Innovation Solution
A method and system that operate a display device by processing both acceleration and orientation information to modify the image content displayed, ensuring a close correlation between the vehicle's acceleration and the visual representation, thereby enhancing the realism of the acceleration experience for the passenger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display device only uses acceleration information to modify displayed content, then the implementation is simple, but the correlation between vehicle acceleration and displayed content is inaccurate, especially when device orientation is not considered
Solution Approach 1:
The patent applies parameter changes by introducing orientation information as an additional parameter to the content modification process. The processing unit modifies displayed content based on both acceleration information and orientation information, where the orientation parameters (roll, pitch, yaw) dynamically adjust how acceleration effects are visualized. This resolves the contradiction by improving correlation accuracy through additional parameters while managing complexity through systematic processing.
Solution Approach 2:
The system implements feedback by continuously obtaining both acceleration information and orientation information, then using this combined feedback to dynamically modify the displayed content. The processing unit adjusts the visualization based on the real-time state of both parameters, creating a closed-loop system that improves accuracy by constantly adapting to the device's actual orientation and acceleration state.
2Measurement precision
If the display device modifies content based on acceleration without considering orientation, then the processing is straightforward, but the visual representation does not accurately reflect the passenger's perceived acceleration
Solution Approach 1:
The patent changes the processing approach by incorporating orientation parameters (roll, pitch, yaw) alongside acceleration data. The processing unit uses these combined parameters to transform the displayed content in a way that accurately reflects the passenger's perceived acceleration. This resolves the contradiction by improving visual representation accuracy while maintaining operational simplicity through automated multi-parameter processing.
3Measurement precision
If the display device processes both acceleration and orientation information, then the correlation between actual acceleration and displayed content is improved, but the processing complexity increases
Solution Approach 1:
The processing unit is designed with multi-functionality to handle both acceleration information and orientation information within a single integrated processing framework. This universal processor can dynamically switch between and combine different types of input data, improving acceleration correlation while avoiding the need for separate processing systems and reducing overall complexity.
Solution Approach 2:
The patent merges the processing of acceleration information and orientation information into a unified content modification process. The processing unit combines both parameter sets to generate the final displayed content transformation, eliminating the need for separate processing pipelines and reducing system complexity while improving correlation accuracy.
