Vehicle AR Interface Adjustment for Inaccurate GPS Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle user interface devices face issues with displaying accurate Augmented Reality (AR) graphic objects due to inaccurate position data, leading to user confusion and shaky displays.
Innovation Solution
A vehicle user interface device that adjusts the position, size, moving speed, and display height of AR graphic objects based on distance data and accuracy of GPS data, with the processor determining the degree and type of change using dilution of precision, vanishing line, and vehicle movement data, ensuring the AR graphic objects are displayed correctly even with inaccurate position data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AR graphic objects are displayed using GPS position data, then navigation information can be provided to users, but display accuracy deteriorates when GPS data is inaccurate causing shaky and incorrect positioning
Solution Approach 1:
The patent introduces an intermediary processing system that receives GPS position data and reconciles it with map data and vanishing point information. This intermediary layer filters and adjusts the GPS data through multiple data sources before displaying AR graphics, thereby maintaining display accuracy even when raw GPS data is inaccurate.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the consistency between GPS position data, map data, and vanishing point calculations. When discrepancies are detected, the system adjusts the AR graphic positioning dynamically, creating a closed-loop control system that maintains accuracy despite input data variations.
2Ease of operation
If AR graphic objects are positioned based on raw GPS data, then implementation is simple, but user confusion increases due to shaky and incorrect display positioning
Solution Approach 1:
The patent introduces an intermediary processing system that receives GPS position data and reconciles it with map data and vanishing point information. This intermediary layer filters and adjusts the GPS data through multiple data sources before displaying AR graphics, thereby maintaining display accuracy even when raw GPS data is inaccurate.
Solution Approach 2:
The system prepares compensatory measures in advance by having map data and vanishing point calculation mechanisms ready. When GPS data accuracy deteriorates, these pre-prepared data sources immediately take effect to cushion the impact, preventing user confusion without requiring complex real-time processing.
3Stability of the object's composition
If AR graphic objects are displayed at fixed positions, then display consistency is maintained, but accuracy deteriorates when position data is inaccurate causing mismatch with real-world locations
Solution Approach 1:
The patent implements dynamic positioning by continuously adjusting AR graphic object positions based on real-time analysis of GPS data, map data, and vanishing point calculations. This dynamic approach allows the system to maintain both consistency and accuracy by adapting to changing data quality conditions.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring the consistency between GPS position data, map data, and vanishing point calculations. When discrepancies are detected, the system adjusts the AR graphic positioning dynamically, creating a closed-loop control system that maintains accuracy despite input data variations.
