Vehicle AR Navigation Map Aligned to Dashboard Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems in vehicles often present users with interpretation difficulties due to vertical display orientations and small details, requiring perspective adjustments that can distract and confuse inexperienced users.
Innovation Solution
An augmented reality display device is calibrated to the interior surface of a vehicle, adapting a three-dimensional navigation map to fit the vehicle's curved surfaces, allowing for a large, intuitively understandable representation that aligns with the user's horizontal perspective, using optical scanning and data communication to ensure seamless integration with the vehicle's environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If navigation displays use vertically oriented display elements in the instrument cluster or central information display, then the display can be integrated into standard vehicle layouts, but the road map becomes difficult to understand intuitively due to rotation and small size
Solution Approach 1:
The patent transitions from traditional 2D vertical displays to a 3D spatial representation where the navigation map is projected onto a transparent surface (windshield or dashboard) in the user's field of view. This dimensional change allows the map to be displayed horizontally in its natural orientation while maintaining integration with the vehicle's existing display architecture through the AR display device.
Solution Approach 2:
The patent introduces an augmented reality display device as an intermediary between the navigation system and the user. This intermediary projects the navigation map onto a transparent surface, mediating the information delivery to preserve both the ease of integration with standard vehicle layouts and the intuitive understanding of the road map through natural horizontal orientation.
2Loss of information
If augmented reality displays are used to show virtual content in relation to the transparent reality, then the information available to the user is improved, but the system requires complex calibration to establish the relationship between display content and the environment
Solution Approach 1:
The patent implements self-calibration functionality where the system automatically performs the calibration process without requiring manual user intervention. The AR display device autonomously establishes the spatial relationship between the projected navigation map and the vehicle interior, reducing device complexity from the user's perspective while maintaining enhanced information delivery.
Solution Approach 2:
The patent performs calibration as a preliminary action during system initialization or setup phase, before the user begins using the navigation system. This preliminary calibration establishes the spatial relationship between the AR display and the vehicle interior in advance, eliminating the need for complex calibration during actual navigation use.
