AR Map Feature Overlay Aligned to the Driver's Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle displays do not consider a driver's specific field of view (FoV) when presenting information, limiting the effectiveness of Roadbook map features in autonomous vehicles.
Innovation Solution
The safety system integrates a processor to analyze sensor data and map data to generate AR display frames that align graphical representations with the driver's FoV, using augmented reality to present road features and information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional in-vehicle displays are used to present Roadbook map features, then the system is simple and easy to implement, but the information is not aligned with the driver's field of view, reducing effectiveness
Solution Approach 1:
The patent transitions from conventional 2D flat displays to 3D spatially-aware augmented reality displays that overlay map features directly onto the driver's field of view. This dimensional change allows information to be presented in the driver's natural viewing space, improving effectiveness without significantly increasing system complexity
Solution Approach 2:
The patent introduces an intermediary processing layer that receives map features, determines their spatial relationship to the driver's field of view, and selectively presents only relevant features. This intermediary component bridges the gap between raw map data and driver needs, improving effectiveness while managing complexity through intelligent filtering
2Loss of information
If all map features are presented on conventional displays, then complete information is provided, but driver attention is分散 and safety is reduced
Solution Approach 1:
The patent applies local quality by selectively presenting map features based on their spatial relationship to the driver's field of view. Only features within or near the driver's FoV are displayed with high prominence, while other features are omitted or shown with reduced detail. This localized approach ensures complete information is available when needed while minimizing distraction
Solution Approach 2:
The patent uses partial action by displaying only the subset of map features that are currently relevant to the driver's view and navigation needs. Rather than presenting all available map information simultaneously, the system selectively displays pertinent features, reducing information overload and driver distraction while maintaining access to complete information when required

AI summary
Techniques are disclosed for using augmented reality (AR) displays to convey graphical representations of different types of information to a user. The information may be obtained from various sources such as objects and/or features that are dynamically detected by a vehicle or user- generated content. The graphical representations may also be based upon information that may be obtained via the use of crowdsourced AV map data. The graphical representations may be presented in as an AR view in a medium (such as a vehicle windshield) that matches a field of view of a user, thus accurately blending holographic information with the physical objects in the scene.
