Windshield AR Navigation Layout for Tactical and Strategic Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional navigation systems in vehicles require drivers to look away from the road to view navigation directions, and existing head-up displays provide only tactical information, which can be cluttered and confusing.
Innovation Solution
A hybrid augmented navigation system that projects tactical and strategic navigation graphics simultaneously on a vehicle's windshield, using a primary viewing envelope divided into tactical and strategic regions, with a tracking camera to monitor the driver's gaze and project navigation data through multiple head-up displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation information is displayed on a traditional infotainment device, then navigation directions are provided to the user, but the user must look away from the road
Solution Approach 1:
The patent transitions navigation display from a traditional 2D infotainment screen to a 3D spatial arrangement using multiple head-up displays positioned at different locations and angles, allowing navigation information to be presented in the driver's peripheral vision without requiring direct gaze
Solution Approach 2:
The patent introduces head-up displays as an intermediary medium between the navigation system and the driver, projecting tactical navigation graphics onto surfaces visible within the driver's field of view, eliminating the need to shift attention from the road
2Reliability
If head-up display is used to project virtual guide, then driver's eyes remain on the road, but only tactical navigation information is provided
Solution Approach 1:
The patent divides navigation information into two distinct segments: tactical navigation graphics (turn-by-turn directions) displayed on head-up displays for immediate guidance, and strategic navigation graphics (landmark information, distance instructions) displayed on a separate strategic display, allowing both types of information to be presented simultaneously without cluttering a single view
Solution Approach 2:
The patent adds a strategic display dimension complementary to the tactical head-up displays, creating a multi-dimensional navigation information architecture where strategic navigation graphics provide contextual information without interfering with tactical guidance visibility
3Loss of information
If traditional map is used for navigation, then comprehensive navigation data is provided, but the display becomes cluttered and confusing for drivers
Solution Approach 1:
The patent segments navigation graphics into tactical elements (arrows, path guidance) and strategic elements (landmark indicia, distance information), distributing them across different display regions and devices to prevent information overload in any single view while maintaining comprehensive navigation data
Solution Approach 2:
The patent applies different display qualities and information densities to different regions: tactical navigation graphics use simplified, high-contrast visual elements for immediate recognition, while strategic navigation graphics provide detailed landmark information in a separate strategic region where comprehensive data can be displayed without interfering with tactical guidance

AI summary
A hybrid augmented navigation system for a vehicle includes a windshield including a primary viewing envelope, the primary viewing envelope including a tactical region and a strategic region, an imaging system including a tracking camera, and a navigation system including navigation data. The hybrid augmented navigation system also includes a controller that is communicatively coupled with the imaging system and the navigation system. The controller is configured to generate a hybrid augmented navigation at the windshield via a hybrid augmented navigation application. The hybrid augmented navigation application includes tactical navigation graphics projected at the tactical region of the primary viewing envelope and strategic navigation graphics projected at the strategic region of the primary viewing envelope. The tactical navigation graphics include a navigation path, and the strategic navigation graphics include landmark indicia based on the navigation data.
