Windshield AR Projector for Driver Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle display screens are small and positioned out of the driver's line of sight, making it difficult for drivers to access important information such as navigation and vehicle parameters while driving.
Innovation Solution
An augmented reality system that projects relevant information, such as route maps and vehicle parameters, onto the windshield using an AR projector, allowing drivers to view critical information without diverting their attention from the road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is displayed on traditional vehicle display screens, then information is provided to drivers, but the screens are small and positioned out of the driver's line of sight requiring attention diversion
Solution Approach 1:
The patent transitions from two-dimensional flat display screens to a three-dimensional augmented reality projection on the windshield, allowing information to be displayed in the driver's forward line of sight without requiring attention diversion to separate display locations
Solution Approach 2:
The patent introduces an augmented reality projection system as an intermediary between the driver and the road, overlaying information directly onto the windshield so the driver can access information while maintaining focus on the road ahead
2Ease of operation
If display screens are positioned within the driver's line of sight, then driver attention is maintained, but the display area becomes limited and may obstruct the view
Solution Approach 1:
The patent uses the windshield's transparent surface as a display medium, utilizing the third dimension of transparency to provide extensive display area without obstructing the driver's view of the road, as information is projected as translucent overlays rather than opaque screens
Solution Approach 2:
The patent projects information at specific locations on the windshield corresponding to the driver's field of view, placing different types of information in different zones to maximize visibility without creating overall obstruction
