Dynamic AR-Map Switching for Driving Guidance Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving information display systems using augmented reality and maps often confuse drivers with excessive switching between guidance modes, making it difficult to provide effective route guidance, especially when multiple guidance points are close together or when road conditions change.
Innovation Solution
A driving information display device that dynamically switches between augmented reality-based and map-based guidance based on predetermined reference distances, vehicle speed, road type, and congestion levels, ensuring that guidance information is output effectively by determining the appropriate mode based on the vehicle's proximity to guidance points and lane guidance points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If augmented reality-based guidance is used for short distances, then guidance clarity is improved, but switching frequency increases causing driver confusion
Solution Approach 1:
The system dynamically adjusts the reference distance based on vehicle speed, allowing the switching threshold to adapt to current driving conditions. At higher speeds, the reference distance increases, reducing switching frequency while maintaining appropriate guidance mode selection
Solution Approach 2:
The system changes the parameter of reference distance according to vehicle speed, transforming it from a fixed value to a variable parameter that responds to driving conditions, thereby optimizing both guidance clarity and switching frequency
2Loss of information
If map-based guidance is used for long distances, then overall route awareness is improved, but guidance effectiveness decreases for upcoming turns
Solution Approach 1:
The guidance system segments the driving route into different zones based on distance to guidance points. Map-based guidance is used for distant sections to show overall route, while augmented reality-based guidance is used for near sections to provide precise turn instructions
Solution Approach 2:
Different guidance modes are applied to different spatial zones along the driving route. The system selects map-based guidance for distant locations and augmented reality-based guidance for nearby locations, optimizing the quality of guidance for each specific zone
3Measurement precision
If switching threshold is set low, then augmented reality guidance is used more often improving clarity, but switching frequency increases causing confusion
Solution Approach 1:
The reference distance parameter is dynamically adjusted based on vehicle speed, transforming it from a fixed low threshold to a variable threshold that increases with speed, thereby reducing unnecessary switching while maintaining clarity when appropriate

AI summary
In a driving information display device and method, the driving information display device includes: a processor configured to receive driving guidance information, and to output map-based guidance information or augmented reality-based guidance information based on the driving guidance information; and a storage unit electrically and communicatively connected to the processor and configured to store road information and an algorithm. The processor is further configured to: receive the location information of a vehicle; identify a driving route of the vehicle and a guidance point; determine the augmented reality-based guidance information to be guidance information to be output when the distance from the location of the vehicle to the guidance point is equal to or shorter than a predetermined first reference distance; determine the map-based guidance information to be the guidance information to be output when the distance from the location of the vehicle to the guidance point exceeds the first reference distance; and generate a control command.
