Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face challenges in accurately correcting the displacement of content position in display images, particularly when a vehicle is traveling through sections with changing inclinations or vibrations, leading to unnecessary corrections and misalignment.
Innovation Solution
A display correction system that includes a predictor to determine specific sections of a travel route with changing inclinations and vibrations, allowing for different control settings to minimize corrections in these sections, thereby improving accuracy and reducing unnecessary adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display correction system continuously corrects display position displacement based on orientation information, then the accuracy of content position is improved, but unnecessary corrections occur in specific sections with changing inclinations or vibrations
Solution Approach 1:
The predictor performs preliminary determination of specific sections (sections with changing inclinations or vibrations) before the moving body actually enters them. By using travel route information and speed information to predict upcoming specific sections, the system can prepare to suspend correction in advance, preventing unnecessary corrections from occurring when the moving body enters these sections. This resolves the contradiction by anticipating problematic conditions before they affect display accuracy.
Solution Approach 2:
The correction control dynamically switches between different modes based on the predicted section type. The system transitions from continuous correction (first control) to suspended correction (second control) when entering specific sections, and back to continuous correction when leaving them. This dynamic adaptation allows the system to maintain high reliability by avoiding unnecessary corrections in problematic sections while preserving measurement precision in normal sections.
2Measurement precision
If the system performs correction under first control in normal sections, then content position accuracy is maintained, but corrections continue unnecessarily in specific sections
Solution Approach 1:
The predictor determines specific sections in advance using travel route information and speed information, allowing the system to suspend correction operations before entering these sections. This preliminary identification prevents wasteful correction operations in sections where corrections would be unnecessary due to changing inclinations or vibrations, thereby reducing energy loss while maintaining accuracy in normal sections.
Solution Approach 2:
The system applies different correction control strategies to different sections of the travel route. In normal sections, continuous correction (first control) is applied to maintain accuracy. In specific sections with changing inclinations or vibrations, correction is suspended (second control) to avoid unnecessary operations. This localized differentiation optimizes energy usage by applying corrections only where they are effective.
3Device complexity
If the system uses a single control mode for correction, then the system complexity is low, but the accuracy deteriorates in specific sections with changing conditions
Solution Approach 1:
The correction control dynamically adapts its behavior based on the type of section the moving body is in. The system switches between first control (continuous correction) and second control (suspended correction) according to predictions from the predictor. This dynamic control mechanism maintains high measurement precision in specific sections without requiring a completely complex system architecture, as the switching logic is driven by the predictor's determination of section types.
Solution Approach 2:
The predictor performs preliminary determination of section types using travel route information and speed information, providing advance notice to the correction system. This allows the correction control to switch modes proactively rather than reactively, maintaining accuracy in specific sections while keeping the overall system complexity manageable through a clear prediction-correction workflow.

AI summary
A display correction system includes a first obtainer, a second obtainer, a third obtainer, a predictor, and a corrector. The first obtainer obtains travel route information on a travel route ahead of a moving body. The second obtainer obtains speed information on a speed of the moving body. The third obtainer obtains orientation information on an orientation of the moving body. The predictor predicts, based on the travel route information and the speed information, a time period during which the moving body travels through a specific section in the travel route. The corrector performs correction of a displacement of a display position of a content on a display image based on the orientation information. Based on prediction result of the predictor, the corrector executes first control when the moving body is traveling in a normal section, and executes second control when the moving body is traveling in the specific section.
