Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges in accurately displaying three-dimensional augmented reality navigation information due to errors caused by the position of the user's eye or vehicle, leading to potential safety risks and reduced user convenience.
Innovation Solution
An electronic device equipped with a communication module, memory, and processor that acquires vehicle position information, determines the availability of high-definition map data, and adjusts navigation information display to either three-dimensional or two-dimensional augmented reality based on this data, using sensors to correct errors and align information with the driver's gaze and lane information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional augmented reality navigation information is displayed using HD map data, then navigation information accuracy and immersion are improved, but position errors occur due to user eye position or vehicle location variations
Solution Approach 1:
The system dynamically switches between 3D and 2D navigation information display modes based on real-time detection of user eye position and vehicle location. When HD map data is available and position errors are within acceptable ranges, 3D augmented reality navigation information is displayed to provide high accuracy and immersion. When position errors exceed thresholds or HD map data is unavailable, the system transitions to 2D navigation information display to ensure reliability and prevent navigation errors.
Solution Approach 2:
The system changes the display parameter (dimensionality) of navigation information based on the availability and quality of HD map data. By monitoring position errors and data availability, the system adjusts between three-dimensional and two-dimensional display modes, optimizing the balance between navigation information accuracy and position reliability under different operating conditions.
2Ease of operation
If three-dimensional augmented reality navigation information is displayed, then user convenience and immersion are improved, but the system complexity increases due to HD map data requirements
Solution Approach 1:
The system dynamically adapts the display mode based on real-time conditions, switching between 3D and 2D navigation information. This dynamic adaptation allows the system to provide high user convenience and immersion when 3D mode is feasible, while automatically falling back to simpler 2D mode when system complexity or data unavailability becomes problematic, thus optimizing the user experience without permanently increasing system complexity.
Solution Approach 2:
The navigation system is designed to support multiple display modes (3D and 2D) within a single unified system. This multi-functionality allows the system to handle various scenarios: providing immersive 3D augmented reality navigation when HD map data is available, and switching to simpler 2D navigation when data is unavailable or system complexity would be excessive, thereby achieving universality across different operating conditions.
3Loss of information
If navigation information is overlaid on actual objects in the real world, then the relevance and usefulness of navigation information are improved, but errors occur due to discrepancies between map data and actual positions
Solution Approach 1:
The system dynamically adjusts the overlay method based on detected position errors and HD map data quality. When position errors are small and HD map data is reliable, the system overlays navigation information on actual objects in the real world to maximize relevance and usefulness. When position errors exceed thresholds or data quality deteriorates, the system switches to alternative overlay methods or 2D display modes to prevent information errors and maintain accuracy.
Solution Approach 2:
The system continuously monitors position errors and HD map data availability, using this feedback to determine the appropriate overlay method. By comparing actual vehicle position with map data and detecting discrepancies, the system adjusts the navigation information display strategy in real-time, switching between 3D object-based overlay and 2D planar display to maintain both relevance and accuracy under varying conditions.

AI summary
A device and a method are provided. The device includes a communication module, a memory, and a processor. The processor is configured to acquire position information of a vehicle via the communication module, determine whether high definition (HD) map information corresponding to the position information is acquired, display three-dimensional (3D) navigation information in augmented reality by using the HD map information when the HD map information is acquired, and display two-dimensional (2D) navigation information in augmented reality when the HD map information is not acquired. The 3D navigation information is information in which virtual 3D graphic information for driving guidance is spatially matched to and displayed on an actual object in the real world by using the HD map information, and the 2D navigation information is information in which virtual 2D graphic information for driving guidance is planarly matched to and displayed on an actual object in the real world.
